TPPU: A Soluble Epoxide Hydrolase Inhibitor
2026-09-14
TPPU is a soluble epoxide hydrolase inhibitor with reported IC50 values of 3.7 nM for human sEH and 2.8 nM for mouse sEH under the supplier’s assay conditions. Its research value lies in testing fatty acid epoxide signaling, inflammatory pain, and the sEH–Nrf2–osteoclastogenesis relationship without implying clinical efficacy. Product specifications are available from the [TPPU C5414 product page](https://www.apexbt.com/tppu.html).

25-Hydroxycholesterol Reprograms Tumor Macrophages
2026-09-13
Xiao et al. identify CH25H-derived 25-hydroxycholesterol as an immunometabolic checkpoint that links lysosomal lipid sensing to AMPKα–STAT6 activation and ARG1 production in tumor-associated macrophages. The study further shows that disrupting CH25H can improve T cell surveillance and enhance anti-PD-1 treatment responses in tumor models.

Bufalin Targets STK33 in Triple-Negative Breast Cancer
2026-09-11
A 2025 Advanced Science study identifies serine/threonine kinase 33 (STK33) as a direct binding and degradation-sensitive target of Bufalin in triple-negative breast cancer. By combining chemical proteomics, biophysical validation, genetic perturbation, animal models, and patient-derived organoids, the work connects STK33 destabilization to disruption of the CCAR1 tumor-promoting axis.

hiPSC Intestinal Organoids for Pharmacokinetic Studies
2026-09-10
A 2025 study established a direct three-dimensional culture strategy for generating expandable intestinal organoids from human induced pluripotent stem cells. The organoids can be cryopreserved, expanded, and converted into two-dimensional intestinal epithelial cultures containing functional enterocyte-like cells, supporting more human-relevant drug absorption and metabolism studies.

MEHP, AhR, and Ovarian Follicle Toxicity
2026-09-10
This reference study shows that mono(2-ethylhexyl) phthalate disrupts mouse ovarian follicle growth and estrogen signaling partly through aryl hydrocarbon receptor activation. Pharmacological blockade with CH 223191 reduced several MEHP-associated effects, providing a mechanistic framework for reproductive environmental toxicology research.

OTUD3, SLC7A11, and Ferroptosis in ccRCC
2026-09-09
The reference study identifies OTUD3-mediated deubiquitination of SLC7A11 as a mechanism that stabilizes cystine uptake, suppresses lipid peroxidation, and promotes sunitinib resistance in clear cell renal cell carcinoma. Its findings connect protein turnover with ferroptosis control and suggest that OTUD3 inhibition could improve the response to ferroptosis-inducing therapy, although clinical transferability remains to be established.

Nanocarrier-Mediated dsRNA Transdermal Delivery
2026-09-09
The reference study defines how a star cationic polymer enables dsRNA to cross the insect cuticle by combining nanocomplex formation, improved wetting, wax-layer dissolution, and reduced chitin-layer resistance. Its interface-focused design provides a mechanistic basis for noninvasive RNAi delivery while clarifying which findings remain specific to the tested polymer and aphid cuticle model.
