Intraperitoneal dissemination is the main method of epithelial ovarian cancer (EOC) metastasis, which is related to poor prognosis and a high recurrence rate. Circular RNAs (circRNAs) are a novel class of endogenous RNAs with covalently closed loop structures that are implicated in the regulation of tumor development. In this study, hsa_circ_0001546 is downregulated in EOC primary and metastatic tissues vs. control tissues and this phenotype has a favorable effect on EOC OS and DFS. hsa_circ_0001546 can directly bind with 14‐3‐3 proteins to act as a chaperone molecule and has a limited positive effect on 14‐3‐3 protein stability. This complex recruits CAMK2D to induce the Ser324 phosphorylation of Tau proteins, changing the phosphorylation status of Tau bound to 14‐3‐3 and ultimately forming the hsa_circ_0001546/14‐3‐3/CAMK2D/Tau complex. The existence of this complex stimulates the production of Tau aggregation, which then induces the accumulation of lipid peroxides (LPOs) and causes LPO‐dependent ferroptosis. In vivo, treatment with ferrostatin‐1 and TRx0237 rescued the inhibitory effect of hsa_circ_0001546 on EOC cell spreading. Therefore, based on this results, ferroptosis caused by Tau aggregation occurs in EOC cells, which is not only in Alzheimer's disease‐ or Parkinson's disease‐related cells and this kind of ferroptosis driven by the hsa_circ_0001546/14‐3‐3/CAMK2D/Tau complex is LPO‐dependent rather than GPX4‐dependent is hypothesized.

Objective To analyze the mutations of the RUNX2 gene in a family with cleidocranial dysplasia (CCD). Methods The general health status of family members with CCD was investigated through propositus verification method. Oral specialized examination and radiological examination were performed. The peripheral venous blood of the proband and her parents and sisters was collected. Genomic DNA was extracted, and the RUNX2 gene from this DNA was amplified by polymerase chain reaction (PCR). DNA sequences were analyzed with the Blastn program. Results After Blastn analysis, heterozygous C to T transition mutation at nucleotide 568 occurred in exon 2, which converted arginine to tryptophane at codon 190 (c.568C>T, CGG→TGG). Conclusion RUNX2 gene is responsible for the CCD in the Chinese family under study. The c.568C>T mutation is the molecular basis of the CCD in the family. [ABSTRACT FROM AUTHOR]

Two cases of cleidocranial dysplasia (CCD) were reported and the characteristics of CCD were analyzed. The propositus verification method was used to family members for general health and oral specialized examination. All patients expressed developmental abnormality of crania, teeth and clavicle.

Background: The clinical outcomes of patients with resected T1-3N0–2M0 non-small cell lung cancer (NSCLC) with the same tumor-node-metastasis (TNM) stage are diverse. Although other prognostic factors and prognostic prediction tools have been reported in many published studies, a convenient, accurate and specific prognostic prediction software for clinicians has not been developed. The purpose of our research was to develop this type of software that can analyze subdivided T and N staging and additional factors to predict prognostic risk and the corresponding mean and median survival time and 1–5-year survival rates of patients with resected T1-3N0–2M0 NSCLC. Results: Using a Cox proportional hazard regression model, we determined the independent prognostic factors and obtained a prognostic index (PI) eq. PI = ∑βixi. =0.379X1–0.403X2–0.267X51–0.167X61–0.298X62 + 0.460X71 + 0.617X72–0.344X81–0.105X91–0.243X92 + 0.305X101 + 0.508X102 + 0.754X103 + 0.143X111 + 0.170X112 + 0.434X113–0.327X122–0.247X123 + 0.517X133 + 0.340X134 + 0.457X143 + 0.419X144 + 0.407X145. Using the PI equation, we determined the PI value of every patient. According to the quantile of the PI value, patients were divided into three risk groups: low-, intermediate-, and high-risk groups with significantly different survival rates. Meanwhile, we obtained the mean and median survival times and 1–5-year survival rates of the three groups. We developed the RNSCLC-PRSP software which is freely available on the web at http://www.rnsclcpps.com with all major browsers supported to determine the prognostic risk and associated survival of patients with resected T1-3N0–2 M0 non-small cell lung cancer. Conclusions: After prognostic factor analysis, prognostic risk grouping and corresponding survival assessment, we developed a novel software program. It is practical and convenient for clinicians to evaluate the prognostic risk and corresponding survival of patients with resected T1-3N0–2M0 NSCLC. Additionally, it has guiding significance for clinicians to make decisions about complementary treatment for patients. [ABSTRACT FROM AUTHOR]
