Diversity of Gut Microbiota and Metabolites in Benign Prostatic Hyperplasia with Different Prostate Volumes. (PubMed, Eur Urol Open Sci) - "Akkermansia (ASV549) may affect prostate volume through the regulation of intestinal amino acid metabolism and may negatively affect prostate-specific antigen levels by inhibiting heat shock protein (HSP) 90 (luminespib)...In this study, we identified the potential associations between gut and both prostate volume and benign prostatic hyperplasia symptoms. These findings suggest that dietary interventions or fecal microbiota transplantation may represent potential strategies for modulating prostate health in the future."

Harnessing Ubiquitin-Proteasome System-Related Genes to Identify Subtypes of Bladder Cancer and Reveal Immune Landscape. (PubMed, Am J Mens Health) - "Somatic mutations demonstrated that the mutation rate of Cluster B was higher than that of Cluster A. In addition, candidate drugs for two clusters of patients were predicted, with Lapatinib, Doramapimod, and SCH772984 may be potential drugs for Cluster A patients. Luminespib, Staurosporine, and Dasatinib may be more suitable for Cluster B patients. The study provides a reference for guiding the clinical treatment of BLCA patients."

Synergistic Inhibition of PI3K and HSP90 Enhanced Antitumorigenic Efficacy in Adrenocortical Carcinoma. (PubMed, Res Sq) - "Quantitative high-throughput drug combination screening identified potent synergy between phosphatidylinositol-3-kinase (PI3K) inhibitor, PIK75 and heat shock protein 90 (HSP90) inhibitors, Ganetespib (STA9090), HSP990, or Luminespib (NVP-AUY922). Further antitumor efficacy was confirmed by the BGT226-STA9090 combination in human ACC xenograft model and five PDOs with different pathogenic mutations. Conclusively, the combinations of PI3K and HSP90 inhibitors were highly effective in preclinical studies, warranting a clinical trial in patients with advanced ACC."

Shared Binding Site but Divergent Resistance Profiles Uncover Novel Resistance Mechanisms in Plasmodium HSP90 Inhibitors. (PubMed, bioRxiv) - "Based on these data, we propose a multi-target hypothesis where AUY-922's lower resistance risk stems from engaging multiple HSP90 family members. Our findings reveal how enhanced drug-target binding can paradoxically correlate with resistance and demonstrate that resistance risk cannot be predicted from binding site identity alone, providing insights for developing more durable drugs across therapeutic areas."

Luminespib protects against dexamethasone-induced hepatic, vascular, and metabolic abnormalities in rats. (PubMed, Naunyn Schmiedebergs Arch Pharmacol) - "According to our results, such outstanding improvements were attributed to (i) restoring cellular oxidant balance (GSH, MDA & NO), (ii) curbing NF-κB/TNF-α/MCP-1 inflammatory cascade, (iii) HSP90 inhibition with reduced expression of glucocorticoid receptors (GR), (iv) reduced expression of the endoplasmic reticulum stress sensors (CHOP & PERK), (v) activation of protein degradation pathways that degrade the misfolded GR including proteasomal degradation (20 S proteasome) and autophagy (BECLIN1). In conclusion, the findings in this study provide valuable insights into the therapeutic potential of LUM in protecting against DEX-induced deleterious effects on hepatic and aortic tissue in order to get the optimum therapeutic outcome from DEX."
