Proteoform-Specific Drug Interactions in Native Membranes
2026-09-02
Lutomski and colleagues introduce a native mass-spectrometry workflow that preserves membrane context while resolving individual receptor, effector, and lipid-modified proteoforms. Using rod-disc membranes, the study reveals how palmitoylation and other lipid modifications influence rhodopsin signalling complexes and how vardenafil and sildenafil interact differentially with retinal PDE6.

HMGCS2, LysoPC, and Pulmonary Fibrosis
2026-09-01
Yang et al. identify injured type II alveolar epithelial cells as a major source of lipid accumulation in bleomycin-associated pulmonary fibrosis and connect reduced HMGCS2 activity with LysoPC-driven fibroblast activation. Their combined lipidomic, genetic, and in vivo experiments define an epithelial lipid-metabolism–fibroblast signaling axis that may guide future fibrosis research.

WIP1/PPM1D, p38 MAPK, and Renal Pyroptosis
2026-08-31
The reference study identifies WIP1/PPM1D as a suppressor of p38 MAPK-driven pyroptosis in sepsis-associated acute kidney injury. By combining single-cell sequencing, human and murine kidney analyses, HK2-cell experiments, and pharmacological inhibition with CCT007093, the authors connect PPM1D activity to the NLRP3–caspase-1–GSDMD axis and provide a mechanistic framework for studying inflammatory renal injury.

QPRT Drives Breast Cancer Invasion via MLC Phosphorylation
2026-08-29
The reference study identifies quinolinate phosphoribosyltransferase (QPRT) as a promoter of breast cancer migration and invasion and links this phenotype to purinergic signaling, Rho–ROCK activity, phospholipase C, and myosin light chain phosphorylation. Its inhibitor-based experiments position PLC signaling pathway modulation as an important mechanistic step, while also highlighting the need for orthogonal validation of pharmacological pathway probes.

Brain-to-Spinal Control of Mechanical Allodynia
2026-08-28
Huo et al. identify a contralateral lPBN^Oprm1–dmH^Pdyn–spinal dorsal horn pathway that regulates both the laterality and persistence of mechanical allodynia in mice. Their circuit, including hypothalamic dynorphin and spinal κ-opioid receptor signaling, provides a mechanistic framework for explaining why similar peripheral insults can produce unilateral, bilateral, transient, or persistent pain hypersensitivity.

Indomethacin A8449: Practical Research Workflow
2026-08-28
Indomethacin (SKU A8449) provides a practical tool for comparing cyclooxygenase inhibition and exploring inflammation, PPAR-associated transcriptional responses, lipid metabolism, and membrane phase behavior. It should be used with vehicle and assay-specific controls, not treated as clinical dosing guidance or as standalone proof of a receptor-specific mechanism.

MAPK10–KRT16 Axis Suppresses NSCLC Metastasis
2026-08-27
The reference study identifies MAPK10 as a metastasis-suppressive kinase that phosphorylates KRT16 at Ser356 and Ser397, enabling RNF213-mediated ubiquitination and proteasomal degradation. Its combination of cellular, mouse-model, and clinical analyses positions the MAPK10/KRT16/RNF213 axis as a mechanistic biomarker framework, while also highlighting the need for further validation before therapeutic translation.
