We identify the microtubule targeting agents lexibulin, colchicine, and combretastatin A-4 as three compounds that bind to the colchicine-binding pocket of the a/b tubulin dimer, and which show increased efficacy in a P47S liver cancer cell line compared to parental cells with WT p53. We find evidence for an unusual mechanism underlying this increased efficacy: our data indicate that the P47S variant shows increased ability to bind to the peptidyl-prolyl isomerase PIN1; this leads to decreased PIN1-cyclin D1 complexes in P47S cells, along with increased cell cycle arrest in response to lexibulin. IMPLICATIONS: These findings support the growing literature that particular mutant forms of TP53 may have specific therapeutic vulnerabilities that can be targetable; improved understanding of these unique vulnerabilities can lead to improved understanding of p53 function.
SCHEMBL4796824, a BPR0L075 derivative with antitumor properties, targets tubulin's colchicine binding site and induces DNA damage response in ovarian cancer...Notably, these effects were more pronounced in c-MYC amplified SK-OV-3 cells. In summary, SCHEMBL4796824 disrupts the canonical Wnt/β-catenin signaling, inducing DNA damage, and inhibits the Wnt/β-catenin/c-MYC axis, triggering cellular senescence in a pathway-dependent manner, hinting at a novel therapeutic approach.
We identified BAP1 as a potential predictive biomarker for JX-594 treatment and explored its underlying mechanisms. However, given that the study used immunodeficient models, the findings reflect tumor-intrinsic interferon responses and require further validation in immunocompetent models to assess immune microenvironment modulation and clinical relevance.
It also regulated apoptosis-related proteins poly(ADP-ribose) polymerase (PARP) and caspase-3 in HSFs. These findings suggest that CYT997 has potential as a targeted therapy for hypertrophic scars by inducing apoptosis in HSFs and reducing fibrotic activity.
