Q-VD-OPh Protocols for Caspase Inhibition
2026-09-29
Q-VD-OPh (SKU A1901) is a cell- and brain-permeable pan-caspase inhibitor for testing whether caspase activity contributes to cell death, post-thaw loss, or disease-model phenotypes. It is suitable for controlled in vitro and model-specific in vivo workflows, but it should not be treated as proof of a single apoptotic pathway or as a universal dose recommendation.

Cisplatin Activates GSDME-Linked Pyroptosis in Gastric Cance
2026-09-28
A medRxiv preprint reports that cisplatin treatment increases GSDME expression in gastric cancer cells and that GSDME knockdown reduces their sensitivity to the drug. The findings point to pyroptosis as a potential part of cisplatin’s activity, while the preprint’s status and the limits of the reported experiments call for cautious interpretation.

0.4% Trypan Blue Solution: Practical Cell Counting
2026-09-27
0.4% Trypan Blue Solution supports cell viability measurement and cell counting by staining cells with compromised membranes while viable cells remain unstained. Use it as a research-only membrane-integrity readout, not as a diagnostic test or a stand-alone method for identifying apoptosis or other specific cell-death pathways.

Cisplatin Resistance: From DNA Damage to Ferroptosis
2026-09-26
Cisplatin (CDDP) is best known for damaging tumor-cell DNA, but resistance can involve survival pathways and alternative cell-death programs. This article examines a lung adenocarcinoma study linking ferroptosis, PI3K/AKT signaling, and cisplatin sensitivity—and explains what that means for assay design.

Ouabain at the Interface of Ion Transport and Senescence
2026-09-25
Ouabain is more than a classic sodium-potassium pump probe: it can help translational teams connect target engagement, ion homeostasis, and context-dependent cell responses. This article outlines how to use it in cardiovascular and senescence research while separating mechanistic evidence from therapeutic claims.

Coumestrol Drives PMAIP1-Linked Ferroptosis in RA-FLS
2026-09-25
A 2026 study reports that Coumestrol suppresses proliferation and inflammatory outputs in rheumatoid arthritis fibroblast-like synoviocytes while promoting ferroptosis. Its mechanistic model links reduced TRIM3-mediated ubiquitination to greater PMAIP1 protein stability, although the evidence is currently limited to cell-based experiments and does not establish estrogen-receptor dependence or clinical efficacy.

IL-1β Sequence Guides Inflammatory Caspase Processing
2026-09-24
The study reports that IL-1β sequence context around its cleavage site helps determine how inflammatory caspases recruit and process the cytokine. It also identifies direct IL-18 cleavage by human caspases-4 and -5, while showing that their cleavage of IL-1β produces a fragment predicted to lack receptor activity.

From Apoptosis Markers to IAP Targeting in CRC
2026-09-23
MDM1 research links p53-regulated apoptosis to colorectal cancer chemoradiotherapy sensitivity. Birinapant (TL32711) offers a distinct way to functionally probe IAP-mediated survival signaling—while the connection between these findings remains a testable hypothesis, not an established combination strategy.

Z-WEHD-FMK for Caspase-1 and Pyroptosis Studies
2026-09-23
Z-WEHD-FMK is a cell-permeable, irreversible inhibitor for separating inflammatory caspase activity from upstream signaling, pyroptosis, and infection-associated organelle remodeling. This guide translates lung cancer findings on caspase-1 regulation into practical assay design while preserving a distinct workflow for Chlamydia and other infectious disease research.

Ibrexafungerp Against Resistant Candida auris
2026-09-22
Wiederhold and colleagues evaluated ibrexafungerp against fluconazole-resistant Candida auris using both susceptibility testing and a delayed-treatment mouse model of invasive candidiasis. The study’s central contribution is evidence that an orally administered glucan-synthesis inhibitor retained activity after infection was established, supporting further investigation of alternative therapies for resistant Candida infections.

TMEM16F in Kupffer Cells Protects Against Listeria
2026-09-21
This study identifies Kupffer cell-expressed TMEM16F as a critical determinant of hepatic protection during Listeria monocytogenes infection, shifting the focus from lymphocytes to liver-resident macrophages. Its findings connect plasma-membrane repair and lipid scrambling with reduced liver injury, controlled inflammation, and preservation of metabolic balance.

RSL3 and GPX4: Reading Cell Death Mechanisms
2026-09-21
RSL3 is a selective glutathione peroxidase 4 inhibitor for dissecting ferroptosis, oxidative stress, and oncogenic RAS vulnerability. This article adds a practical cell-death interpretation framework by contrasting GPX4-driven ferroptosis with the RNA Pol II degradation-dependent apoptosis described in a recent Cell study.
