Improvement of Vascular Function by Knockdown of Salusin-β in Hypertensive Rats via Nitric Oxide and Reactive Oxygen Species Signaling Pathway.

Purpose: Salusin-β, a multifunctional vasoactive peptide, has a potentially important function in the pathological development of hypertension. However, the exact functional role of salusin-β and the underlying mechanism in this process are still not fully understood. The current study aimed to investigate the effects of silencing salusin-β on vascular function and vascular remodeling, as well as its signaling pathways in spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY).

Imaging manifestations of Caroli disease with autosomal recessive polycystic kidney disease: a case report and literature review.

TISCH: a comprehensive web resource enabling interactive single-cell transcriptome visualization of tumor microenvironment.

Cancer immunotherapy targeting co-inhibitory pathways by checkpoint blockade shows remarkable efficacy in a variety of cancer types. However, only a minority of patients respond to treatment due to the stochastic heterogeneity of tumor microenvironment (TME). Recent advances in single-cell RNA-seq technologies enabled comprehensive characterization of the immune system heterogeneity in tumors but posed computational challenges on integrating and utilizing the massive published datasets to inform immunotherapy.

Carbon nanocage-based nanozyme as an endogenous HO-activated oxygenerator for real-time bimodal imaging and enhanced phototherapy of esophageal cancer.

Intelligent phototherapy by theranostic nanosystems that can be activated by a tumor microenvironment has high sensitivity and specificity. However, hypoxia and low drug accumulation in tumors greatly limit its clinical application. Herein, we have designed a cage-like carbon-manganese nanozyme, which effectively relieves tumor hypoxia and delivers numerous photosensitizers (PSs) to the tumor site, for real-time imaging and enhanced phototherapy of esophageal cancer.

Drug-induced chronic cough and the possible mechanism of action.

Chronic cough is defined as a cough lasting for ≥8 weeks with a normal chest radiograph. The common causes of chronic cough are cough variant asthma (CVA), upper airway cough syndrome/postnasal drip syndrome (UACS/PNDs), eosinophilic bronchitis (EB), gastroesophageal reflux-related chronic cough (GERC) and atopic cough (AC). Drug-induced chronic cough, a rare cause of chronic cough, refers to a chronic cough caused by certain drugs.

Transcriptome profiling analysis reveals that ATP6V0E2 is involved in the lysosomal activation by anlotinib.

Anlotinib is a receptor tyrosine kinase inhibitor with potential anti-neoplastic and anti-angiogenic activities. It has been approved for the treatment of non-small-cell lung cancer. Lysosomes are acidic organelles and have been implicated in various mechanisms of cancer therapeutics.

miR-155 Accelerates the Growth of Human Liver Cancer Cells by Activating CDK2 via Targeting H3F3A.

miR-155 is associated with the promotion of tumorigenesis. Herein, we indicate that abnormal miR-155 was negatively correlated with the expression of P21WAF1/Cip1. Our results suggest that miR-155 alters the transcriptome and inhibits the expression of H3F3A in liver cancer cells.
