CGRP Protects Bladder Smooth Muscle Cells Stimulated By High Glucose through Inhibiting p38 MAPK Pathway In Vitro

Researchers indicated that calcitonin gene-related peptide (CGRP) protected bladder smooth muscle cells from oxidative stress induced by high glucose in vitro, and inhibit the α-SM-actin expression decrease through inhibiting the intracellular p38 MAPK signaling pathway.

Physiological and Pharmacological Stimulation for In Vitro Maturation of Substrate Metabolism in Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes

Researchers investigated substrate metabolism in hiPSC-CMs grown as a monolayer and in 3D, in porous collagen-derived scaffolds and in engineered heart tissue, by measuring rates of glycolysis and glucose and fatty acid oxidation, and changes in gene expression and mitochondrial oxygen consumption.
