Verteporfin can Reverse the Paclitaxel Resistance Induced by YAP Over-Expression in HCT-8/T Cells without Photoactivation through Inhibiting YAP Expression.
Paclitaxel (PTX) is one of the most effective anti-cancer drugs. However, multiple drug resistance is still the main factor that hinders the effective treatment of cancer with PTX. Several factors including YAP over-expression can cause PTX resistance. In this study, we aimed to verify the role YAP plays in PTX resistance, explore the reversal of PTX resistance by verteporfin (VP) and investigate the effect of combination therapy of PTX and VP on the PTX resistant colon cancer cells (HCT-8/T). ⋯ VP can reverse the PTX resistance induced by YAP over-expression in HCT-8/T cells without photoactivation through inhibiting YAP expression.

Circulating miR-181a as a Potential Novel Biomarker for Diagnosis of Acute Myocardial Infarction.
In this study, we tested the hypothesis that miR-181a levels increase during acute myocardial infarction. We investigated circulating miR-181a as a potential novel biomarker for early diagnosis of acute myocardial infarction (AMI). ⋯ Circulating miR-181a levels in patients with AMI were significantly changed in a time-dependent manner, indicating the value of plasma miR-181a as a novel biomarker for diagnosing AMI.

PHLDA1 Promotes Lung Contusion by Regulating the Toll-Like Receptor 2 Signaling Pathway.
Lung contusion is a potentially lethal injury. Pleckstrin homology-like domain family A, member-1 (PHLDA1) is known to play crucial roles in cell proliferation and apoptosis. In this study, we investigated the biological role of PHLDA1 in lung contusion. ⋯ These results demonstrate that PHLDA1 plays a critical role in the development of progressive lung contusion and subsequent inflammation. This information furthers our understanding of the pathogenesis of lung contusion, and suggests that PHLDA1 blockade may represent a potential therapeutic strategy for the treatment of this injury.

MiR-155 is Involved in Renal Ischemia-Reperfusion Injury via Direct Targeting of FoxO3a and Regulating Renal Tubular Cell Pyroptosis.
Ischemia/reperfusion injury (IRI) plays a crucial role in renal transplantation and can cause renal failure associated with pyroptosis, a pro-inflammatory-induced programmed cell death. Small endogenous non-coding RNAs have been shown to be involved in renal ischemia/reperfusion injury. This study was performed to investigate which miRNAs regulate pyroptosis in response to renal ischemia/reperfusion injury and determine the mechanism underlying this regulation. ⋯ Our study proposes a new signaling pathway of miR-155/FoxO3a/ARC leading to renal pyroptosis under ischemia/reperfusion injury conditions.

Geniposide Prevents Hypoxia/Reoxygenation-Induced Apoptosis in H9c2 Cells: Improvement of Mitochondrial Dysfunction and Activation of GLP-1R and the PI3K/AKT Signaling Pathway.
Myocardial ischemia/reperfusion injury is a major cause of morbidity and mortality associated with coronary heart disease. Many studies have demonstrated that natural products are promising chemotherapeutic drugs counteracting the loss of cardiomyocytes. Thus, the purpose of the present study was to investigate the effects of geniposide, a traditional Chinese herb extract from Gardenia jasminoides J. Ellis, on cardiomyocyte apoptosis induced by hypoxia/reoxygenation (H/R) in H9c2 cells, and their underlying mechanisms. ⋯ Our results suggest that geniposide pretreatment inhibits H/R-induced myocardial apoptosis by reversing mitochondrial dysfunction, an effect in part due to activation of GLP-1R and PI3K/AKT signaling pathway.
