Erythropoietin-Derived Peptide Protects Against Acute Lung Injury After Rat Traumatic Brain Injury.
Traumatic brain injury (TBI) can be complicated by TBI-triggered acute lung injury (ALI), in which inflammation plays a central role. It has been reported that an Erythropoietin-derived peptide (pHBSP) was able to ameliorate TBI; however, its function in TBI-caused ALI has not been reported yet. ⋯ We identified the protective role that pHBSP played in TBI-caused ALI, suggesting that pHBSP is a potent candidate for systemic therapy in TBI patients.

MicroRNA-29b Inhibits Angiogenesis by Targeting VEGFA through the MAPK/ERK and PI3K/Akt Signaling Pathways in Endometrial Carcinoma.
The purpose of this study is to explore the effects of microRNA-29b (miR-29b) regulating MAPK/ERK and PI3K/Akt signaling pathways on angiogenesis in endometrial carcinoma (EC) by targeting VEGFA. ⋯ Our results indicate that miR-29b negatively modulates the MAPK/ERK and PI3K/Akt signaling pathways to inhibit angiogenesis in EC by targeting VEGFA.

Resveratrol Protects Against Pulmonary Arterial Hypertension in Rats via Activation of Silent Information Regulator 1.
The polyphenol resveratrol (Rev) has been found to exhibit various beneficial effects including prevention of pulmonary arterial hypertension (PAH). The present study was designed to investigate the action and potential mechanism of Rev on PAH, focusing on the role of SIRT1 (Silent Information Regulator 1) in apoptosis of pulmonary artery smooth muscle cells (PASMCs). ⋯ Rev produced a beneficial effect partially by enhancing the activation of SIRT1, thus improving RVSP and reducing RVH. SIRT1 activation increased PASMC apoptosis by inducing mPT dysfunction, which might be a novel future strategy for the treatment of PAH.

ReviewAtherosclerosis and the Hydrogen Sulfide Signaling Pathway - Therapeutic Approaches to Disease Prevention.
Hydrogen sulfide (H2S) is now admitted as a third gasotransmitter together with nitric oxide (NO) and carbon monoxide (CO), albeit it was originally considered as a foul and poisonous gas. Endogenous H2S production in mammalian cells is counting on the three enzymes acting on cysteine. Involvement of H2S in various physiological and pathological processes has been extensively studied in the last fifteen years. ⋯ Exogenous H2S supplement has salutary effects on atherogenesis, and reduction of the endogenous H2S level accelerates atherosclerosis. The anti-atherosclerotic mechanisms of H2S have been descried in different aspects, including endothelium preservation, antioxidative action, anti-inflammatory responses, vasorelaxation, regulation of ion channels, etc. However, further investigation is still needed to help us gain more insights into the fundamental underlying mechanisms, and that will allow us to design better therapeutic applications of H2S in the treatment of atherosclerosis.

LncRNA SNHG6 is Associated with Poor Prognosis of Gastric Cancer and Promotes Cell Proliferation and EMT through Epigenetically Silencing p27 and Sponging miR-101-3p.
Background/Amis: Long non-coding RNAs (lncRNAs), a novel class of transcripts, have been shown to play critical roles in diverse cellular biological processes, including tumorigenesis. Small nucleolar RNA host gene 6 (SNHG6) regulates various biological processes in cancer cells. However, the biological role of SNHG6 in gastric cancer still remains to be explored. The aim of this study is to investigate the characteristic of the SNHG6 in gastric cancer.
