ETS1–SENP2 Signaling in Bronchopulmonary Dysplasia
2026-09-01
The reference study identifies ETS1 as a transcriptional regulator of mitochondrial quality control in hyperoxia-induced bronchopulmonary dysplasia. Its central mechanism links ETS1-driven SENP2 expression to FUNDC1 deSUMOylation, HSPA8-dependent FUNDC1 degradation, and suppression of excessive mitophagy, although the reported abstract contains one structural-outcome phrase that requires verification against the full article.

Protein A/G Magnetic Co-IP/IP Kit Workflow
2026-08-31
Build faster, more reproducible immunoprecipitation workflows for protein-complex isolation, western blotting, mass spectrometry, and antibody purification. Magnetic separation and broad Fc-region binding make this format especially useful when sample quantity, complex stability, or processing time is limiting.

Blebbistatin: Mechanism, Uses, and Assay Limits
2026-08-30
(±)-Blebbistatin is a cell-permeable non-muscle myosin II inhibitor that targets the myosin-ADP-Pi intermediate and suppresses actin-activated ATPase activity. Its reversible control of contractility makes Blebbistatin useful for cell migration, adhesion, morphology, and cytoskeletal dynamics assays, but isoform selectivity, solvent handling, and assay-specific potency must be controlled.

Berberine Targets RAGE/POMC in Metabolic Disease
2026-08-28
A 2026 pre-proof study identifies RAGE as a central nervous system target of berberine within Tianhuang Formula and connects RAGE/POMC signaling with hypothalamic neuronal apoptosis, autophagy, and glucolipid regulation. Its integrated computational, cellular, and mouse-model design provides a useful framework for studying neuronal mechanisms of metabolic disease while leaving translation to neurodegenerative disorders unresolved.

SAN-Plexus Assembloids and Pacemaker Maturation
2026-08-28
This Cell Stem Cell study develops human pluripotent stem cell-derived sinoatrial node–cardiac plexus assembloids that reproduce key structural, molecular, and electrophysiological features of neuro-modulated pacemaker systems. By combining assembloid function with spatial transcriptomics of human sinoatrial node tissue, the authors identify a prosaposin–GPR37 signaling axis associated with pacemaker maturation and establish a platform for studying conduction dysfunction.

Tetrazolium (chloride) Workflows for Viability
2026-08-27
Tetrazolium (chloride), also called Tetrazolium Red, converts mitochondrial dehydrogenase activity into a visible red formazan signal for cell and tissue analysis. This guide connects plate-based viability assays with ischemic brain staining, emphasizing controls, quantification, and troubleshooting rather than treating color intensity as a standalone mechanistic answer.

RBMS1 Loss Rewires PD-L1 Immunity in TNBC
2026-08-27
The reference study identifies RBMS1 as an RNA-binding protein that sustains PD-L1 stability in immune-cold triple-negative breast cancer through B4GALT1-dependent glycosylation. Its depletion increased tumor-cell susceptibility to T-cell attack and improved responses to immune-based treatments, providing a mechanistic framework for combination strategies.

Carboplatin Workflows for Cancer Research
2026-08-26
Carboplatin is a platinum-based DNA synthesis inhibitor that supports reproducible cytotoxicity, DNA-damage, and resistance studies across ovarian and lung cancer models. This workflow emphasizes stock preparation, matched 2D–3D testing, proteomics-informed interpretation, and troubleshooting for variable drug response.

Serine/Glycine-Free Diet in CRC Immunity
2026-08-26
Tong et al. show that a serine/glycine-free diet can restrict colorectal cancer growth while increasing cytotoxic T-cell activity, yet simultaneously promote immune escape through PD-L1 lactylation. The study links dietary metabolism to checkpoint regulation and provides early clinical evidence that this intervention is feasible and safe, supporting combination strategies rather than diet-only treatment.

HLTP1 Targets JNK in Hepatic Ischemia–Reperfusion Injury
2026-08-25
A 2026 World Journal of Gastroenterology study used peptidomics of human liver-transplant samples to identify human liver transplantation peptide 1 (HLTP1), an endogenous peptide that reduced hepatic ischemia-reperfusion injury in mice and protected AML12 hepatocytes. The findings connect HLTP1 activity to suppressed Jun N-terminal kinase phosphorylation and provide a mechanistically testable framework for studying apoptosis during liver transplantation.

5X Protein Loading Buffer (Reducing) Guide
2026-08-24
5X Protein Loading Buffer (Reducing) standardizes denaturation, disulfide-bond reduction, and tracking-dye addition before conventional SDS-PAGE electrophoresis. It is intended for reducing, denaturing protein molecular weight separation and should not be used when native structure or intact disulfide bonds must be preserved.
