Loss of Ephrin B2 Receptor (EPHB2) Sets Lipid Rheostat by Regulating Proteins DGAT1 and ATGL Inducing Lipid Droplet Storage in Prostate Cancer Cells

Knockdown strategies for EPHB2 were performed in prostate cancer cells to analyze the impact on the net lipid balance, proliferation, triacylglycerol-regulating proteins, effect on lipid droplet (LD) biogenesis, and intracellular localization of LDs.

S-Adenosylmethionine Upregulates the Angiotensin Receptor-Binding Protein ATRAP via the Methylation of HuR in NAFLD

The authors explored the effect of supplementary S-adenosylmethionine, which was the main biological methyl donor in mammalian cells, in regulating AT1R-associated protein (ATRAP), which was the negative regulator of AT1R.

Long QT Syndrome 2 PAS Domain Variant Induces hERG1a/1b Subunit Imbalance in Patient-Specific iPSC-Cardiomyocytes

hiPSCs were derived from a long QT syndrome type 2 (LQT2) patient carrying the Per-Arnt-Sim (PAS) domain variant hERG1-H70R. CRISPR/Cas9 gene editing produced isogenic control iPSC lines. Differentiated iPSC-derived cardiomyocytes were evaluated for their electrophysiology, hERG1a/1b mRNA expression, and hERG1a/1b protein expression.
