Netrin-1 Impairs Adipogenesis in Obesity
2026-09-24
This study identifies adipose-derived Netrin-1 as a brake on adipocyte differentiation, linking its effects to reduced PPARγ activity and increased Wnt/β-catenin signaling. In mice, loss and overexpression experiments associate Netrin-1 with adipose remodeling and glucose regulation, suggesting that the capacity to form new adipocytes may matter as much as total fat mass.

BHQ: SERCA Inhibition in Calcium Signaling Research
2026-09-23
2,5-di-tert-butylbenzene-1,4-diol (BHQ) is a SERCA inhibitor used to investigate intracellular calcium storage and calcium homeostasis disruption. A 2025 mouse study reports that BHQ increased hematopoietic stem cell mobilization through a SERCA–CaMKII–STAT3–CXCR4 pathway, but it does not establish a human treatment effect.

Trilaurin: Practical Protocols for Lipid Workflows
2026-09-22
Trilaurin, also called Glycerol Tridodecanoate, provides a defined C12 triacylglycerol for lipid formulation, enzymatic synthesis, and selected biomedical workflows. It should be used as a lipid-phase component or biocatalytic synthesis substrate after compatibility testing, not as a water-soluble reagent or stand-alone evidence of oral or anticancer efficacy.

2-APB: IP3R Antagonist for Calcium Signaling
2026-09-18
2-APB, also called 2-aminoethoxydiphenyl borate, is a cell-permeable probe for IP3R-mediated calcium release and related TRPC channel activity. Its benchmarked effects support studies of store-operated calcium entry inhibition, calcium oscillations and waves, and ER-Ca2+-dependent cell fate, but its channel selectivity is limited.

Drug Repurposing for CRISPR DNA Repair Control
2026-09-17
This Nature Communications study presents a large drug-repurposing screen that links clinically used compounds to NHEJ, MMEJ, HDR, cell survival, and synthetic-lethal responses after CRISPR-induced DNA breaks. Its combination of mutational outcome profiling and genetic follow-up identifies repair-pathway regulators, including ESR2 and AOX1, while providing a framework for tuning genome-editing outcomes without introducing a new drug discovery program.
