Cross-Cell-Line Machine Learning for Compound MoA
2026-09-28
Warchal and colleagues compared morphology-feature tree classification with image-based convolutional neural networks to predict compound mechanism of action across distinct breast cancer cell lines. Both approaches performed comparably within cell lines, but the tree classifier transferred more effectively to an unseen line, highlighting cell context as a central challenge for phenotypic profiling.
ISX-9 Boosts Circadian Amplitude Through BMAL1
2026-09-27
The study identifies ISX-9 as a small molecule that sustains circadian reporter amplitude and improves several daily physiological rhythms in middle-aged mice. Its proposed mechanism links calcium signaling and CaMKIIδ to phosphorylation-dependent activation of BMAL1, suggesting a route to strengthen circadian oscillations without deliberately shifting clock timing.
Bovine Insulin for Melanoma Metabolism Assays
2026-09-26
Use Bovine insulin as a controlled culture variable when testing how kinase inhibitors reshape melanoma-cell growth and metabolism—not as a substitute for the inhibitors or metabolic probes in the research. This practical guide pairs an insulin dose screen with ROS, PDH, and growth readouts, while flagging formulation and interpretation pitfalls.
RP3-340N1.2 Stabilizes IL-6 mRNA in NSCLC
2026-09-26
A 2026 study reports that the lncRNA RP3-340N1.2 supports non-small cell lung cancer cell proliferation and migration by limiting ZC3H12A-associated degradation of IL-6 mRNA. Knockdown reduced these tumor-associated phenotypes and affected macrophage polarization, providing a post-transcriptional mechanism to investigate in NSCLC models.
SmD2 Acetylation Links Splicing to PARP Sensitivity in HCC
2026-09-25
A 2024 study connects acetylation-dependent control of the spliceosome protein SmD2 with BRCA1/FANC alternative splicing, DNA-damage repair, and PARP-inhibitor response in hepatocellular carcinoma.
