October 2022 "Systolic heart failure (HF) is a chronic clinical syndrome characterized by the reduction salient alterations that confer significant hormonal burden on the already compromised function of the failing mineralocorticoid receptor antagonists, which block the effects of angiotensin II (AngII) and aldosterone on the failing almost all aldosterone, of all epinephrine, and of a significant amount of norepinephrine reaching the failing

October 2022 "The role of different G protein-coupled receptors (GPCRs) in the cardiovascular system is well understood in cardiomyocytes and vascular smooth muscle cells (VSMCs). In the former, stimulation of Gs-coupled receptors leads to increases in contractility, whereas stimulation of Gq-coupled receptors modulates cellular survival and hypertrophic responses. In VSMCs, stimulation of GPCRs also modulates contractile and cell growth phenotypes. Here, we will focus on the relatively less well-studied effects of GPCRs in cardiac fibroblasts, focusing on key signaling events involved in the activation and differentiation of these cells. We also review the hierarchy of signaling events driving the fibrotic response and the communications between fibroblasts and other cells in the heart. We discuss how such events may be distinct depending on where the GPCRs and their associated signaling machinery are localized in these cells with an emphasis on nuclear membrane-localized receptors. Finally, we explore what such connections between the cell surface and nuclear GPCR signaling might mean for cardiac fibrosis." Read more at the source #DrGPCR #GPCR #IndustryNews

When antibodies fail to selectively recognize GPCR targets, the resulting data can be difficult to reproduce

Drug discovery programs rarely fail because an assay produced poor data. They fail because the interpretation of that data did not translate to biology outside the assay system Failure Is the Real Curriculum Drug discovery carries a difficult truth: most programs fail. Yet failure is not a sign of weakness in discovery science. to failure without loss of enthusiasm.

The key is consistency: define which pathway defines “selectivity,” and stay faithful to it. Compounds fail when assumptions about selectivity prove wrong in vivo.
