A Decrease of Histone Deacetylase 6 Expression Caused by Helicobacter Pylori Infection is Associated with Oncogenic Transformation in Gastric Cancer.
Histone deacetylase 6 (HDAC6) plays a role in the progression of many tumors. However, the relationship between the level of HDAC6 expression and gastric tumorigenesis is still unclear. Here, we illustrate the potential correlation between Helicobacter pylori (HP) infection and the variation of HDAC6 expression in different gastric lesions, as well as the clinical significance of HDAC6 expression in gastric cancer (GC) patients. ⋯ HDAC6 is a promising biomarker for early diagnosis and prognosis during the oncogenic transformation of gastric cancer.

Roscovitine, a CDK5 Inhibitor, Alleviates Sevoflurane-Induced Cognitive Dysfunction via Regulation Tau/GSK3β and ERK/PPARγ/CREB Signaling.
Multiple exposures to anesthesia in children may increase the risk of developing cognitive impairment. Sevoflurane is an anesthetic that is commonly used in children during surgery. Cyclin-dependent kinase (CDK) 5 is involved in the regulation of sevoflurane-induced cognitive dysfunction, but the mechanistic details remain unclear. The present study evaluated the mechanism by which CDK5 mediates sevoflurane-induced cognitive dysfunction in mice. ⋯ Inhibiting CDK5 with roscovitine has neuroprotective effects against neuronal injury and cognitive dysfunction caused by sevoflurane anesthesia that are exerted via modulation of Tau/GSK3β and ERK/PPARγ/CREB signaling.

Higher Numbers of T-Bet+ Tumor-Infiltrating Lymphocytes Associate with Better Survival in Human Epithelial Ovarian Cancer.
T-bet, a member of the T-box family of transcription factors, is a key marker of type I immune response within the tumor microenvironment, and has been previously reported by us to serve as an important prognostic indicator for human gastric cancer patients and a potential biomarker for immunotherapy. In the present study, we aimed to assess the clinical significance and prognostic value of T-bet+ tumor-infiltrating lymphocytes in human epithelial ovarian cancer. ⋯ Our data indicated that the key transcription factor T-bet might play an important role in the type I immune cells mediated antitumor response, and the density of T-bet+ lymphocytes in human epithelial ovarian cancer tissues could serve as a prognostic predictor for ovarian cancer patients.

Salvianolic Acid A Protects Against Diabetic Nephropathy through Ameliorating Glomerular Endothelial Dysfunction via Inhibiting AGE-RAGE Signaling.
Glomerular endothelium dysfunction leads to the progression of renal architectonic and functional abnormalities in early-stage diabetic nephropathy (DN). Advanced glycation end products (AGEs) and receptor for AGEs (RAGE) are proved to play important roles in diabetic nephropathy. This study investigated the role of Salvianolic acid A (SalA) on early-stage DN and its possible underlying mechanism. ⋯ Our study indicated that SalA restored glomerular endothelial function and alleviated renal structural deterioration through inhibiting AGE-RAGE, thus effectively ameliorated early-stage diabetic nephropathy. SalA might be a promising therapeutic agent for the treatment of diabetic nephropathy.

Heat Shock Protein A12B Protects Vascular Endothelial Cells Against Sepsis-Induced Acute Lung Injury in Mice.
Pulmonary endothelial injury is a critical process in the pathogenesis of acute lung injury (ALI) during sepsis. Heat shock protein A12B (HSPA12B) is mainly expressed in endothelial cells and protects against several harmful factors. However, the effects of HSPA12B in sepsis-induced ALI and its potential mechanisms of action remain unclear. ⋯ HSPA12B protected against sepsis-induced ALI. The potential mechanism may be partly due to the inhibition of ERK phosphorylation and caspase-3 activation. These findings provide a potential therapeutic target for treating sepsis.
