Nidogen 2 Overexpression Promotes Hepatosteatosis and Atherosclerosis.

Clinical and genetic studies strongly support a significant connection between nonalcoholic fatty liver disease (NAFLD) and atherosclerotic cardiovascular disease (ASCVD) and identify ASCVD as the primary cause of death in NAFLD patients. Understanding the molecular factors and mechanisms regulating these diseases is critical for developing novel therapies that target them simultaneously. Our preliminary immunoblotting experiments demonstrated elevated expression of nidogen 2 (NID2), a basement membrane glycoprotein, in human atherosclerotic vascular tissues and murine steatotic livers.

Smooth muscle cell-specific CD47 deletion suppresses atherosclerosis.

Background: Recent smooth muscle cell (SMC)-lineage tracing and single-cell RNA sequencing (scRNA-seq) experiments revealed a significant role of SMC-derived cells in atherosclerosis development. Further, thrombospondin-1 (TSP1), a matricellular protein, and activation of its receptor cluster of differentiation (CD) 47 have been linked with atherosclerosis. However, the role of vascular SMC TSP1-CD47 signaling in regulating VSMC phenotype and atherogenesis remains unknown.

Near-Infrared Visualization of NAD(P)H Dynamics in Live Cells and Larvae Using a Coumarin-Based Pyridinium Fluorescent Probe.

A near-infrared fluorescent probe, , was designed by substituting the carbonyl group of the coumarin dye's lactone with a 4-cyano-1-methylpyridinium methylene group and then attaching an electron-withdrawing NADH-sensing methylquinolinium acceptor via a vinyl bond linkage to the coumarin dye at the 4-position. The probe exhibits primary absorption maxima at 603, 428, and 361 nm, and fluoresces weakly at 703 nm. The addition of NAD(P)H results in a significant blue shift in the fluorescence peak from 703 to 670 nm, accompanied by a substantial increase in fluorescence intensity.

Anti-tumor efficacy of : Suppressing liver cancer by targeting tumor-associated macrophages.

Despite significant advances in our understanding of the molecular pathogenesis of liver cancer and the availability of novel pharmacotherapies, liver cancer remains the fourth leading cause of cancer-related mortality worldwide. Tumor relapse, resistance to current anti-cancer drugs, metastasis, and organ toxicity are the major challenges that prevent considerable improvements in patient survival and quality of life. (CB), an ancient Chinese medicinal drug, has been used to treat various pathologies, including stroke, convulsion, epilepsy, pain, and cancer.

Hydrogen sulfide donor activates AKT-eNOS signaling and promotes lymphatic vessel formation.

The lymphatic network is pivotal for various physiological functions in the human body. Accumulated evidence supports the role of therapeutic lymphangiogenesis in the treatment of several pathologies. Endogenous gasotransmitter, hydrogen sulfide (H2S) has been extensively studied for its potential as a pro-angiogenic factor and vascular function modulator.
