luminespib (AUY922)

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.

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.

Additionally, drugs like AUY922 and AZ628 showed considerable potential in treating BC. RT-qPCR results for these four genes in clinical samples aligned with the bioinformatics findings. This study identified and validated four prognostic genes-ZIC2, CD24, CEBPD, and CCL19-that are associated with BC and may provide novel targets for diagnostic and therapeutic strategies.

AUY922 can compensate for the high toxicity and instability of traditional inducers in RD modeling. These results not only enrich our understanding of the toxicology of AUY922 but also provide clues for establishing reliable RD models.

It systematically investigates the effects of HSP90 inhibitors, including AUY922, B11B021, CCT-018159, D7-gedunin, geldanamycin, and gedunin, across a range of cancer cell lines (HCC151, HT29, MCF7, PC3, VCAP, and A375) and a normal HA1E cell line, using data from the CLUE database...The findings suggest that HSP90 inhibitors exhibit varying mechanisms of action across different cancer cell lines despite the presence of some common targets. These insights highlight the need for further investigation into the precise mechanisms of HSP90 inhibitors to optimize their therapeutic potential in different cancers.

We developed a WNT-derived subtyping method to identify SCC from canonical CRC, which enhances the molecular understanding of this severe cancer subtype and provides potential therapeutic strategies. Our findings suggest that SCC patients may benefit from the HSP90 inhibitor NVP-AUY922, highlighting its potential as a targeted therapy.

Besides, the drug sensitivity analysis showed that the low -risk subgroup was notably sensitive to Salubrinal, Lenalidomide, Metformin, while high -risk subgroup was more responsive to Docetaxel, AUY922, Embelin. Eventually, two clusters of LSCC samples had notable correlations with LSCC prognosis. The above results indicated that the risk model consisted of TMRGs (SERPINA1, TMC8, RENBP, SDS and FAM107A) was constructed in LSCC, contributing to studies related to the prognosis and treatment of LSCC.

A statistically significant difference in the efficacy of sorafenib was found between the two CFRG score groups...Molecular docking analysis revealed that DLAT and SLC2A1 had a strong binding affinity toward camptothecin, rapamycin, dactolisib, and luminespib. The correlation between the CFRG score and single-cell characteristics was further explored. The study depended on our understanding of the biological function of CFRGs in HCC and provided new insights for developing treatment strategies.

These findings highlight the antiproliferative effects and anticancer activity of the AUY922/cisplatin combination in cisplatin-resistant NPC cells. The combination treatment of AUY922 and cisplatin holds promise as a strategy to overcome drug resistance in NPC patients.

In addition, the high-risk group exhibited lower half-maximal inhibitory concentration values for specific chemotherapy medications, including bortezomib, luminespib, rapamycin, and 5-fluorouracil. Our study elucidates the diagnostic and prognostic value of mitochondria-related-lncRNAs in the promotion, suppression, and treatment of glioma.

Our findings highlighted the suggestion of targeting HSP90 in GAC therapy via down-regulating YAP1/TEAD signaling. Additionally, our results suggest that AUY922's ability to reshape the GAC TME favoring the host sets the stage for a clinical trial that combines HSP90 and checkpoint inhibition, where HSP90 could serve as a biomarker for patient selection.
