Abstract

We aimed to investigate the role and mechanism of LSP1 in the progression of acute myelogenous leukemia. In this study, we established shLSP1 cell line to analyze the function of LSP1 in AML. We observed high expression of LSP1 in AML patients, whereas it showed no expression in normal adults. Furthermore, we found that LSP1 expression was associated with disease prognosis. Our results indicate that LSP1 plays a crucial role in mediating proliferation and survival of leukemia cells through the KSR/ERK signaling pathway. Additionally, LSP1 promotes cell chemotaxis and homing by enhancing cell adhesion and migration. We also discovered that LSP1 confers chemotactic ability to leukemia cells in vivo. Finally, our study identified 12 genes related to LSP1 in AML, which indicated poor survival outcome in AML patients and were enriched in Ras and cell adhesion signaling pathways. Our results revealed that the overexpression of LSP1 is related to the activation of the KSR/ERK signaling pathway, as well as cell adhesion and migration in AML patients. Reducing LSP1 expression impair AML progression, suggesting that LSP1 may serve as a potential drug therapy target for more effective treatment of AML.

Abstract

The study aimed to investigate the effects of different anesthesia methods on the analgesia, inflammation and oxidative stress levels and cognitive function in elderly patients undergoing hip replacement. 100 elderly patients requiring hip replacement and admitted to Tianjin Hospital from March 2017 to March 2019 were enrolled and divided into group A (n=35, general anesthesia with endotracheal intubation), group B (n=35, epidural anesthesia) and group C (n=30, general anesthesia with endotracheal intubation + epidural anesthesia). The basic vital signs, inflammatory factors, stress response indicators and cognitive function changes were compared among three groups. Additionally, the effects of three different anesthesia methods were analyzed based on the differences in postoperative analgesic effect, extubation time and recovery time. The vital signs [systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR)] were lower in group C than those in group A and group B after surgery (p

Abstract

Herkinorin is an opiate analgesic with limited adverse effects, functioning as a primary selective atypical opioid µ agonist. The present study aimed to identify whether herkinorin has a positive effect on ischemic/reperfusion (I/R) injury. Adult male C57BL/6 mice were randomly divided into five groups: i) Naive, ii) sham, iii) I/R, iv) I/R with dimethyl sulfoxide (I/R+D) and v) I/R with herkinorin (I/R+H). The I/R injury model was induced by occluding the middle cerebral artery for 1 h followed by 24 h or 7 days of reperfusion. Neurobehavioral scores and sensorimotor functions were examined 24 h and 7 days following reperfusion. In addition, infarct volumes were examined at these time points using a 2,3,5‑triphenyltetrazolium chloride assay. Herkinorin treatment improved neurobehavioral and sensorimotor functional recovery from I/R‑induced brain injury. There was a significant decrease in infarct volume in the I/R+H group at 24 h or 7 days following reperfusion compared with the I/R and I/R+D groups. Western blotting suggested that the decrease in conventional protein kinase C γ (cPKCγ) membrane translocation in the peri‑infarct region may be attenuated by herkinorin pretreatment. These results indicated that herkinorin may be beneficial in I/R‑induced mouse brain injury, and this may be attributed to the membrane translocation of cPKCγ following activation.
