Candida krusei Apoptosis in Bovine Mammary Cells
2026-09-15
Miao et al. show that Candida krusei yeast and hypha phases both trigger apoptosis in bovine mammary epithelial cells, but they preferentially engage different signaling routes. The work links fungal morphology to mitochondrial or death ligand/receptor mechanisms and identifies TLR2/ERK and JNK/ERK signaling as modulatory nodes relevant to Candida mastitis research.

Separating Growth Arrest from Cell Death in Cancer
2026-09-11
Hannah R. Schwartz’s dissertation shows that relative viability and fractional viability measure different dimensions of anticancer drug response and should not be treated as interchangeable. By separating proliferative arrest from cell killing and considering their distinct timing, the study provides a more interpretable framework for in vitro cancer research and assay design.

Cabazitaxel (XRP6258) Resistant Model Guide
2026-09-11
Cabazitaxel (XRP6258) provides a practical taxane option for studying microtubule dynamics disruption in P-glycoprotein-expressing and other taxane-resistant cancer models. It is intended for controlled DMSO- or ethanol-based workflows, not water-based assays, and prepared solutions should be used promptly rather than stored long term.

PGE2-Driven Schwann Cell Dedifferentiation in PDAC
2026-09-09
Wang et al. identify a spatially organized PTGES–PGE2 signaling axis in which pancreatic ductal adenocarcinoma promotes Schwann cell dedifferentiation and the secretion of LIF and ADAMTS-1, thereby supporting perineural invasion. By integrating transcriptomic, spatial, single-cell, coculture, and three-dimensional perturbation experiments, the study connects tumor-derived prostaglandin signaling with neural remodeling and directional invasion.
