Metastasis is the leading cause of cancer-related mortality. Paneth cells provide stem cell niche factors in homeostatic conditions, but the underlying mechanisms of cancer stem cell niche development are unclear. Here, we report that Dickkopf-2 (DKK2) is essential for the generation of cancer cells with Paneth cell properties during colon cancer metastasis. Splenic injection of Dkk2 knockout (KO) cancer organoids into C57BL/6 mice resulted in a significant reduction of liver metastases. Transcriptome analysis showed reduction of Paneth cell markers such as lysozymes in KO organoids. Single-cell RNA sequencing analyses of murine metastasized colon cancer cells and patient samples identified the presence of lysozyme positive cells with Paneth cell properties including enhanced glycolysis. Further analyses of transcriptome and chromatin accessibility suggested hepatocyte nuclear factor 4 alpha (HNF4A) as a downstream target of DKK2. Chromatin immunoprecipitation followed by sequencing analysis revealed that HNF4A binds to the promoter region of Sox9, a well-known transcription factor for Paneth cell differentiation. In the liver metastatic foci, DKK2 knockout rescued HNF4A protein levels followed by reduction of lysozyme positive cancer cells. Taken together, DKK2-mediated reduction of HNF4A protein promotes the generation of lysozyme positive cancer cells with Paneth cell properties in the metastasized colon cancers.

Abstract Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative diseases that exist on a clinico-pathogenetic spectrum, designated ALS/FTD. The most common genetic cause of ALS/FTD is expansion of the intronic hexanucleotide repeat (GGGGCC) n in C9orf72. Here, we investigate the formation of nucleic acid secondary structures in these expansion repeats, and their role in generating condensates characteristic of ALS/FTD. We observe significant aggregation of the hexanucleotide sequence (GGGGCC) n , which we associate to the formation of multimolecular G-quadruplexes (mG4s) by using a range of biophysical techniques. Exposing the condensates to G4-unfolding conditions leads to prompt disassembly, highlighting the key role of mG4-formation in the condensation process. We further validate the biological relevance of our findings by detecting an increased prevalence of G4-structures in C9orf72 mutant human motor neurons when compared to healthy motor neurons by staining with a G4-selective fluorescent probe, revealing signal in putative condensates. Our findings strongly suggest that RNA G-rich repetitive sequences can form protein-free condensates sustained by multimolecular G-quadruplexes, highlighting their potential relevance as therapeutic targets for C9orf72 mutation-related ALS/FTD.

Here, the authors track the evolution of mass distribution through bird evolution challenging suggested coupling between body shape and centre-of-mass position, and instead showing that crouched bipedalism evolved after powered flight.

Here, the authors examine how body size, shape, and segment proportions correspond to ecology in models of 410 tetrapods. They find variable allometric relationships, differential scaling in small and large animals, and body proportions as a potential niche occupation mechanism.

IntroductionThe visual signals evoked at the retinal ganglion cells are modified and modulated by various synaptic inputs that impinge on lateral geniculate nucleus cells before they are sent to the cortex. The selectivity of geniculate inputs for clustering or forming microcircuits on discrete dendritic segments of geniculate cell types may provide the structural basis for network properties of the geniculate circuitry and differential signal processing through the parallel pathways of vision. In our study, we aimed to reveal the patterns of input selectivity on morphologically discernable relay cell types and interneurons in the mouse lateral geniculate nucleus.MethodsWe used two sets of Scanning Blockface Electron Microscopy (SBEM) image stacks and Reconstruct software to manually reconstruct of terminal boutons and dendrite segments. First, using an unbiased terminal sampling (UTS) approach and statistical modeling, we identified the criteria for volume-based sorting of geniculate boutons into their putative origins. Geniculate terminal boutons that were sorted in retinal and non-retinal categories based on previously described mitochondrial morphology, could further be sorted into multiple subpopulations based on their bouton volume distributions. Terminals deemed non-retinal based on the morphological criteria consisted of five distinct subpopulations, including small-sized putative corticothalamic and cholinergic boutons, two medium-sized putative GABAergic inputs, and a large-sized bouton type that contains dark mitochondria. Retinal terminals also consisted of four distinct subpopulations. The cutoff criteria for these subpopulations were then applied to datasets of terminals that synapse on reconstructed dendrite segments of relay cells or interneurons.ResultsUsing a network analysis approach, we found an almost complete segregation of retinal and cortical terminals on putative X-type cell dendrite segments characterized by grape-like appendages and triads. On these cells, interneuron appendages intermingle with retinal and other medium size terminals to form triads within glomeruli. In contrast, a second, presumed Y-type cell displayed dendrodendritic puncta adherentia and received all terminal types without a selectivity for synapse location; these were not engaged in triads. Furthermore, the contribution of retinal and cortical synapses received by X-, Y- and interneuron dendrites differed such that over 60% of inputs to interneuron dendrites were from the retina, as opposed to 20% and 7% to X- and Y-type cells, respectively.ConclusionThe results underlie differences in network properties of synaptic inputs from distinct origins on geniculate cell types.

Abstract Background Canine idiopathic pulmonary fibrosis (CIPF) is a chronic, progressive, interstitial fibrosing lung disease, manifesting as cough, exercise intolerance and ultimately, dyspnea and respiratory failure. It mainly affects West Highland white terriers (WHWTs), lacks curable treatment and has a poor prognosis. Aspiration of gastroesophageal refluxate may play a role in the development of CIPF. In the first part of this study, we completed label-free quantitative proteomic analysis of bronchoalveolar lavage fluid (BALF) from CIPF and healthy WHWTs. In the second part, we evaluated potential protein markers of reflux aspiration from canine gastric juice and vomitus and whether these were present in BALF from the two groups. Results Across all BALF samples, 417 proteins were identified, and of these, 265 proteins were identified by two or more unique tryptic peptides. Using the 265 high confidence assignments, the quantitative proteome profiles were very similar in the two cohorts, but they could be readily resolved by principal component analysis on the basis of differential protein expression. Of the proteins that were differentially abundant in the two groups, several (including inflammatory and fibrotic markers) were elevated in CIPF, and a smaller, more diverse group of proteins were diminished in CIPF. No protein markers indicative of reflux aspiration were identified. Conclusions Label-free proteomics allowed discrimination between CIPF and healthy WHWTs, consistent with fibrotic process but did not provide clear evidence for gastrointestinal aspiration. The measurement of proteins may provide a proteomics signature of CIPF that could be used to evaluate treatment options.

Purpose: High-grade gliomas in infants and very young children (less than 3 to 5 years old) pose significant challenges due to the limited scientific literature available and high risks associated with treatments. This study aims to investigate their characteristics, treatment, and outcomes., Methods: A cohort study was conducted at Children's Cancer Hospital, Egypt. Cases included children aged < 5 years old with confirmed CNS high-grade glioma. Baseline clinical and radiological characteristics, besides potential prognostic factors were assessed., Results: In total, 76 cases were identified, 7 of them were < 1 year old. Gross- or near-total resection (GTR/NTR) was achieved in 32.9% of all cases. Of the tested cases, H3K27M-alteration was present in 5 subjects only. The 3-year OS and EFS for all cases were 26.9% and 15.4%, respectively. Extent of resection was the most important prognostic factor, as those achieving GTR/NTR experienced more than double the survival compared to those who do not (p = 0.05). Age had a "bimodal" effect on EFS, with those aged 1 to 3 years old faring better than younger and older age groups. Subjects with midline tumors had worse survival compared to non-midline tumors (1-year EFS = 18.5% vs 35%, respectively, p = 0.02)., Conclusion: This study in a large cohort of HGG in infants and very young children offers insights into the characteristics and treatment challenges. Extent of resection, age group, and tumor localization are important prognostic factors. Further research with larger sample size is warranted to refine treatment approaches and improve outcomes., (© 2024.

Delayed healing of chronic wounds results in amputation and mortality rates in serious cases. The present study examines the merged wound-restorative efficacy of injectable bone marrow-derived mesenchymal stem cells (BMMSCs) and topical Callyspongia sp. extract in immunocompromised rats. HR-LC-MS analysis of Callyspongia sp. extract tentatively identified twenty-nine compounds (1-29) and highlighted its richness in fatty acids and terpenoids, known for their wound regenerating efficacies. The wound closure was greatly prominent in the BMMSCs/Callyspongia sp. group in contrast to the control group (p<0.001). The RT-PCR gene expression emphasized these results by attenuating the oxidative, inflammatory, and immunity markers, further confirmed by histopathological findings. Additionally, in silico modeling was particularly targeting matrix metalloproteinase-9 (MMP9), a key player in wound healing processes. Computational analysis revealed that compounds 18 and 19 potentially modulate MMP9 activity. The combination of BMMSCs and topical Callyspongia sp. extract holds a promise for regenerative therapy constituting a drastic advance in the wound cure of immunocompromised patients, eventually further safety assessments and clinical trials are required., (© 2024 Wiley-VHCA AG, Zurich, Switzerland.)

Background and Objective: PD-1 inhibitors have revolutionized cancer therapies and are being used to treat an expanding array of cancers. To best serve patients, clinicians should be familiar with the spectrum of skin manifestations associated with PD-1 inhibitor therapy. Here, we report a unique case of hypertrophic lichen planus (HLP) in a 64-year-old man treated with pembrolizumab; the presentation initially suggested a squamous cell carcinoma (SCC) morphology, then evolved into a morphology more typical of hypertrophic lichen planus. This case underscores the need for caution in diagnosing eruptive SCCs associated with PD-1 inhibitor therapy. In such instances, maintaining a high suspicion for lichenoid reactions as sequelae of PD-1 inhibitor treatment and starting an empiric trial of therapy for lichenoid dermatitis may be warranted to ensure timely management of lesions., Methods: We describe a case of hypertrophic lichen planus mimicking squamous cell carcinoma in the setting of PD-1 inhibitory therapy with pembrolizumab. A PubMed literature review was conducted to identify other cases and determine the incidence of lichenoid reactions imitating squamous cell carcinoma in the setting of PD-1 inhibitor use., Results: Our case is one of the few available pieces of literature describing eruptive hypertrophic lichen planus imitating SCC in the setting of PD-1 inhibitor use. Initial skin nodule biopsy appeared histologically compatible with squamous cell carcinoma. Repeat biopsy of the skin lesions revealed histological features consistent with hypertrophic lichen planus. Over time, lower extremity lesions evolved into a more typical appearance of hypertrophic lichen planus. Treatment with topical 0.05% clobetasol ointment and oral acitretin 25 mg led to complete resolution of lesions within 2-3 months., Conclusions: This case underscores the significance of maintaining vigilance for lichenoid reactions as potential sequelae of PD-1 inhibitor therapy. It highlights the variability in initial presentation and the potential for lesions to transform over time. Timely recognition and appropriate management, including high-potency topical corticosteroids and oral acitretin, are crucial for achieving favorable outcomes in patients experiencing such reactions. More studies are necessary to fully analyze the rate of HLP occurrence as a consequence of PD-1 inhibitor use., (© 2024. The Author(s).)

Background: Pure germinomas account for 40% of pineal tumors and are characterized by the lack of appreciable tumor markers, thus requiring a tumor biopsy for diagnosis. MicroRNAs (miRNA) have emerged as potential non-invasive biomarkers for germ cell tumors and may facilitate the non-invasive diagnosis of pure pineal germinomas., Material and Methods: A retrospective chart review was performed on all patients treated at the Children's Cancer Hospital Egypt diagnosed with a pineal region tumor between June 2013 and March 2021 for whom a research blood sample was available. Plasma samples were profiled for miRNA expression, and DESeq2 was used to compare between pure germinoma and other tumor types. Differentially expressed miRNAs were identified. The area under the curve of the receive;r operating characteristic curve was constructed to evaluate diagnostic performance., Results: Samples from 39 pediatric patients were available consisting of 12 pure germinomas and 27 pineal region tumors of other pathologies, including pineal origin tumors [ n = 17; pineoblastoma ( n = 13) and pineal parenchymal tumors of intermediate differentiation ( n = 4)] and others [ n = 10; low-grade glioma ( n = 6) and atypical teratoid rhabdoid tumor ( n = 4)]. Using an adjusted p -value <0.05, three miRNAs showed differential expression (miR-143-3p, miR-320c, miR-320d; adjusted p = 0.0058, p = 0.0478, and p = 0.0366, respectively) and good discriminatory power between the two groups (AUC 90.7%, p < 0.001) with a sensitivity of 25% and a specificity of 100%., Conclusion: Our results suggest that a three-plasma miRNA signature has the potential to non-invasively identify pineal body pure germinomas which may allow selected patients to avoid the potential surgical complications., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Fakhry, Elayadi, Elzayat, Samir, Maher, Taha, El-Beltagy, Refaat, Zamzam, Abdelbaki, Sayed, Kieran and Elhaddad.)

Atypical teratoid rhabdoid tumor (ATRT) is a rare type of potentially fatal childhood brain tumor. The present study aimed to examine the overall survival (OS) and event-free survival (EFS) outcomes of pediatric patients with ATRT and to analyze the impact of different prognostic factors, including age, sex, tumor site and size, metastatic disease, the extent of resection, radiotherapy, and chemotherapy, on survival. The present study included 47 patients with ATRT treated at the Children's Cancer Hospital of Egypt (Cairo, Egypt) between July 2007 and December 2017. These patients were treated according to the Dana-Farber Cancer Institute protocol 02-294 for 51 weeks. Various prognostic factors, including age, sex, tumor size and initial metastatic status, exhibited no impact on the radiological response measured at 6 weeks and at the end of treatment. The primary tumor site significantly affected the response to treatment at 6 weeks (P=0.008). Toxicity-related mortality occurred in 29.8% of patients. The median duration of the treatment protocol was 66.9 weeks. The duration of treatment was in the present cohort was longer than the actual 51 weeks of the protocol due to prolonged supportive care of the included patients. Patients who encountered toxicity received reduced dose of chemotherapy in the subsequent cycles in the protocol. Age, initial metastatic status, tumor site and resection extent did not significantly affect the patient outcomes. Preoperative tumor size significantly affected the EFS (P=0.03) and OS (P=0.04). Radiotherapy administration significantly affected the OS (P<0.001) and EFS (P<0.001). The median EFS and OS of patients were 9.3 and 10.3 months, respectively. A total of 24 (51.1%) patients exhibited disease progression or recurrence. The progression sites were local (n=6), metastatic (n=9) or both local and metastatic (n=9). The results of the present study demonstrated that the therapeutic regimen should be patient-adjusted to maintain the treatment intensity and avoid toxicity-related mortality. In lower middle-income countries, short and intensified induction followed by consolidation of treatment, either by single or tandem autologous stem cell transplant, is needed to avoid prolonged exposure to myelosuppression and toxicity-related mortality., Competing Interests: The authors declare that they have no competing interests., (Copyright: © El-Hemaly et al.)

Background and Objectives: Children and Youth with Special Health Care Needs have high healthcare utilization, fragmented care, and unmet health needs. Accountable Care Organizations (ACOs) increasingly use pediatric care management to improve quality and reduce unnecessary utilization. We evaluated effects of pediatric care management on total medical expense (TME) and utilization; perceived quality of care coordination, unmet needs, and patient and family experience; and differential impact by payor, risk score, care manager discipline, and behavioral health diagnosis., Methods: Mixed-methods analysis including claims using quasi-stepped-wedge design pre and postenrollment to estimate difference-in-differences, participant survey, and semistructured interviews. Participants included 1321 patients with medical, behavioral, or social needs, high utilization, in Medicaid or commercial ACOs, and enrolled in multidisciplinary, primary care-embedded care management., Results: TME significantly declined 1 to 6 months postenrollment and continued through 19 to 24 months (-$645.48 per member per month, P < .001). Emergency department and inpatient utilization significantly decreased 7 to 12 months post-enrollment and persisted through 19 to 24 months (-29% emergency department, P = .012; -82% inpatient, P < .001). Of respondents, 87.2% of survey respondents were somewhat or very satisfied with care coordination, 56.1% received education coordination when needed, and 81.5% had no unmet health needs. Emergency department or inpatient utilization decreases were consistent across payors and care manager disciplines, occurred sooner with behavioral health diagnoses, and were significant among children with above-median risk scores. Satisfaction and experience were equivalent across groups, with more unmet needs and frustration with above-median risk scores., Conclusions: Pediatric care management in multipayor ACOs may effectively reduce TME and utilization and clinically provide high-quality care coordination, including education and family stress, with high participant satisfaction., (Copyright © 2023 by the American Academy of Pediatrics.)

Background: The pediatric pulmonary multisystem Langerhans cell histiocytosis (PPM LCH) is associated with either low risk or high risk organ(s). The nodulo-cystic lung lesions although pathognomonic, yet are very variable in severity and remain a source of controversy in certifying pulmonary LCH diagnosis. The study aimed to examine the prognostic value of clinical respiratory manifestations and radiological lung lesions severity. This is through associating a CT chest triad of bilateral, extensive and diffuse lesions. It is a retrospective study of 350 LCH patients who received systemic treatment at Children's Cancer Hospital Egypt during the period from 2007 to 2020., Results: Sixty-seven patients (67/350-19.1%) had PPM LCH at presentation. Severe lung lesions were present in 24 of them. The median follow-up period was 61 months (IQR: 3.4-8.3). The 5-year overall survival (OS) and event free survival (EFS) was 89% and 56.6% respectively. The EFS, for severe radiological lesions triad was 38% ± 20.7 versus 66% ± 16.2 for non-severe lesions triad p 0.002, while for presence of chest X-ray changes 27% ± 22.344 versus absence of chest X ray changes 66% ± 14.7 p 0.001, for clinical respiratory manifestations 13% ± 13.9 versus none 62% ± 22.9 p < 0.001, for RO- with severe lung lesions 47% ± 30.4 versus RO- without severe lung lesions 69% ± 5.9 p 0.04. There was a tendency for the independent prognostic impact of severe lung involvement; aHR = 1.7 (95% CI 0.92-3.13, p = 0.09)., Conclusion: Although the lung is a low -risk organ per se in LCH, our study demonstrates a non negligeable prognostic impact of severe lung involvement in the risk stratification of pediatric LCH. This warrants further study and external validation., (© 2023. The Author(s).)

Background: Skin lightening products (SLPs) are popular among women for medical and non-medical reasons. Therefore, this study aimed to determine the extent of SLP use among women, identify their sources of information, explore factors associated with SLP use and SLP related knowledge, attitudes, and practices (KAP) among women in the UAE., Methods: A structured questionnaire in English and Arabic was distributed to women in the UAE. The questionnaire included demographic characteristics, knowledge (10 items), attitudes (10 items), practices (9 items), and four additional questions on SLP use. Adequate KAP scores were defined as a score of ≥70% out of the maximum score for each KAP section. Chi-square tests were used to test associations between demographic characteristics, dichotomized KAP scores, and SLP use., Results: The study included 370 participants, 50% of the respondents were aged 18-24, and 40% were from the Middle East, 64.8% were unmarried, 91% had university degrees, and 50% had healthcare related profession. Among the respondents 25% use SLPs, the majority use SLPs for non-medical reasons. Employment status is significantly associated with SLP use. The percentage of participants with a knowledge, attitude, and practice score of ≥70% is 66.48%, 76.75%, and 74.72% respectively. Type of profession was significantly associated knowledge and practice. In addition, nationality was also associated with practice., Conclusion: This study highlighted knowledge, attitude and practice gaps and varied levels of SLP-related KAP among women in the UAE. To promote the rational use of SLPs, educational campaigns and stricter regulations are necessary., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Mitochondria (MT) participate in most metabolic activities of mammalian cells. A near-unidirectional mitochondrial transfer from T cells to cancer cells was recently observed to "metabolically empower" cancer cells while "depleting immune cells," providing new insights into tumor-T cell interaction and immune evasion. Here, we leverage single-cell RNA-seq technology and introduce MERCI, a statistical deconvolution method for tracing and quantifying mitochondrial trafficking between cancer and T cells. Through rigorous benchmarking and validation, MERCI accurately predicts the recipient cells and their relative mitochondrial compositions. Application of MERCI to human cancer samples identifies a reproducible MT transfer phenotype, with its signature genes involved in cytoskeleton remodeling, energy production, and TNF-α signaling pathways. Moreover, MT transfer is associated with increased cell cycle activity and poor clinical outcome across different cancer types. In summary, MERCI enables systematic investigation of an understudied aspect of tumor-T cell interactions that may lead to the development of therapeutic opportunities., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2023 Elsevier Inc.

The treatment of glioblastoma has limited clinical progress over the past decade, partly due to the lack of effective drug delivery strategies across the blood-brain-tumor barrier. Moreover, discrepancies between preclinical and clinical outcomes demand a reliable translational platform that can precisely recapitulate the characteristics of human glioblastoma. Here we analyze the intratumoral blood-brain-tumor barrier heterogeneity in human glioblastoma and characterize two genetically engineered models in female mice that recapitulate two important glioma phenotypes, including the diffusely infiltrative tumor margin and angiogenic core. We show that pulsed laser excitation of vascular-targeted gold nanoparticles non-invasively and reversibly modulates the blood-brain-tumor barrier permeability (optoBBTB) and enhances the delivery of paclitaxel in these two models. The treatment reduces the tumor volume by 6 and 2.4-fold and prolongs the survival by 50% and 33%, respectively. Since paclitaxel does not penetrate the blood-brain-tumor barrier and is abandoned for glioblastoma treatment following its failure in early-phase clinical trials, our results raise the possibility of reevaluating a number of potent anticancer drugs by combining them with strategies to increase blood-brain-tumor barrier permeability. Our study reveals that optoBBTB significantly improves therapeutic delivery and has the potential to facilitate future drug evaluation for cancers in the central nervous system., (© 2023.

MINERvA has measured the ν&#95;{μ}-induced coherent π^{+} cross section simultaneously in hydrocarbon (CH), graphite (C), iron (Fe), and lead (Pb) targets using neutrinos from 2 to 20 GeV. The measurements exceed the predictions of the Rein-Sehgal and Berger-Sehgal PCAC based models at multi-GeV ν&#95;{μ} energies and at produced π^{+} energies and angles, E&#95;{π}>1  GeV and θ&#95;{π}<10°. Measurements of the cross-section ratios of Fe and Pb relative to CH reveal the effective A scaling to increase from an approximate A^{1/3} scaling at few GeV to an A^{2/3} scaling for E&#95;{ν}>10  GeV.

Background: Posterior fossa tumor is a type of brain tumor that is located at the borders of both the brain stem and cerebellum. The cerebellum is the brain region in charge of balance and coordination. Pediatric patients diagnosed with posterior fossa tumor have been reported to fall frequently., Objectives: The aim of this study is to investigate the effectiveness of balance and coordination training in these children., Methods: This randomized control clinical trial (ClinicalTrials.gov Identifier: NCT04528316) was carried out between September 2020 and April 2021 at Children's Cancer Hospital-57357. The inclusion criteria were patients with posterior fossa tumor in maintenance phase and, age between 5 and 12 years. The exclusion criteria were patients who had a genetic disorder or suffer from mental retardation, a chronic lung disease, severe cardiomyopathy, or a neuromuscular disease that does not relate to tumor. The study participants were randomly assigned into three groups: Group I/Control group: they received Pilates core stability exercises program, Group II/Postural stability group: they received the same program plus HUMAC balance program, and Group III/Coordination group: they received the same program plus coordination exercises of BOT-2. The semi-parametric proportional odds model was used to compare follow-up scores of the Postural stability group vs Control, and Coordination group vs Control, while adjusting for baseline values. All tests were two sided, with alpha set to 0.05., Results: Sixty children including 38 boys and 22 girls were enrolled in this study. In all three groups, postural stability and coordination improved significantly in terms of modified clinical test of sensory integration of balance, center of pressure, limits of stability, bilateral coordination, and upper-limb coordination., Conclusion: The current study supports the value of adding postural stability and coordination training to the physiotherapy plan for children with posterior fossa tumor., Trial Registration Number and Date of Registration: ClinicalTrials.gov Identifier: NCT04528316 on August 27, 2020., (© 2022.

Neutrino-induced charged-current single π^{+} production in the Δ(1232) resonance region is of considerable interest to accelerator-based neutrino oscillation experiments. In this Letter, high statistic differential cross sections are reported for the semiexclusive reaction ν&#95;{μ}A→μ^{-}π^{+}+ nucleon(s) on scintillator, carbon, water, iron, and lead targets recorded by MINERvA using a wideband ν&#95;{μ} beam with ⟨E&#95;{ν}⟩≈6  GeV. Suppression of the cross section at low Q^{2} and enhancement of low T&#95;{π} are observed in both light and heavy nuclear targets compared with phenomenological models used in current neutrino interaction generators. The cross sections per nucleon for iron and lead compared with CH across the kinematic variables probed are 0.8 and 0.5 respectively, a scaling which is also not predicted by current generators.
