AZD8055

Drug sensitivity prediction showed lower predicted half-maximal inhibitory concentration (IC50) values for selected agents, including AZD8055, in the high-risk subgroup, suggesting a potential association with pharmacogenomic drug-response patterns...RT-qPCR confirmed downregulation of ABCG4 and GPX3 and upregulation of SERPINE1 in GC cell lines. These findings identified prognostic features associated with uric acid metabolism in gastric cancer and suggest that ABCG4, SERPINE1, and GPX3 may be involved in metabolic dysregulation, matrix remodeling, and predicted pharmacogenomics response patterns.

The synergistic effects of the MEK inhibitor trametinib combined with the mTOR inhibitor AZD8055 or the pan-CDK inhibitor flavopiridol were evaluated in PDOs and validated in matched PDXs. We also validated PDOs in predicting clinical gemcitabine/paclitaxel (Gem/PTX) responses...The trametinib/AZD8055 combination is a promising precision therapeutic strategy, and PDOs can serve as a reliable tool to guide clinical therapy selection. Despite limitations such as small sample size, lack of tumor microenvironment and immune components in the model system, this work provides important preclinical evidence for the clinical translation of PDOs in the personalized therapy of PDAC.

INPP4B, SLCO1B3, LIPH, TGM2, ACSL5, SLC2A1, and EPHX2 were identified as hypoxia- and lipid metabolism-related prognostic genes in PC. Distinct immune cell subsets were also characterized during PC progression. These findings provide a foundation for further mechanistic studies and potential prognostic applications.

This work set up a prognostic model for LUAD based on 8 MDRGs, pinpointing promising biomarkers and targets for LUAD treatment.

To investigate this, we utilized CRISPR/Cas9 technology to delete ULK1 in EOC cell lines OVCAR8, HEYA8, ES2 and the fallopian tube epithelial cell line FT190. Treatment of metastatic patient-derived organoids with the clinical ULK1 inhibitor DCC-3116, MEK inhibitor trametinib, or mTORC1/2 inhibitor AZD-8055 reduced viability in a subset of these samples, reflecting inter-patient heterogeneity and need for biomarker-guided selection. Overall, this study highlights ULK1 as a critical regulator of multiple steps of EOC disease progression, underscoring its potential as a therapeutic target in advanced ovarian cancer.

Drug sensitivity profiling unveiled a positive and statistically significant association between ADAM15 and AZD-8055 and Nitazoxanide, whereas a negative correlation was observed with Oxaliplatin and Ponatinib. Our study underscores the multifaceted role of ADAM15 in cancer progression, immune evasion, and response to therapy. By elucidating the intricate interplay between ADAM15 and the tumor microenvironment (TME), we have identified novel diagnostic biomarkers and potential therapeutic avenues.

Notably, the TLS_H group demonstrated enhanced sensitivity to chemotherapeutics including AZD8055, axitinib, vorinostat, nilotinib, camptothecin and paclitaxel. Real-time fluorescent quantitative PCR (RT-qPCR) validation in Mia PaCa2 and Jurkat cells indicated that LAT, RBP5 and SKAP1 may play important roles in modulating sensitivity to these chemotherapeutics. These findings establish TLS as a potential biomarker for PAAD, enabling personalised chemotherapy selection by integrating immune contexture and genomic drivers to improve clinical outcomes.

The constructed 4-gene hypoxia-lactylation prognostic model can effectively predict survival risk in LGG patients. The high-risk group is characterized by activation of pro-tumorigenic pathways, high immune infiltration, and sensitivity to specific targeted drugs. FABP5 + TAMs participate in LGG progression by regulating lipid metabolism and inflammatory responses, representing a potential therapeutic target.

This study reveals that ITPRIPL1 plays a dual role in glioma: It suppresses T cell-mediated immune responses, contributing to an immunosuppressive microenvironment, and interferes with the efficacy of antitumor drugs, thereby promoting tumor progression and ultimately leading to poor patient prognosis.

To prevent incorrect selection of a reference gene in dormant tumor cells, we analyzed the expression stability of the widely used housekeeping genes GAPDH, ACTB, TUBA1A, RPS23, RPS18, RPL13A, PGK1, EIF2B1, TBP, CYC1, B2M, and YWHAZ in the T98G, A549, and PA-1 cancer cell lines treated with the dual mTOR inhibitor AZD8055...The optimal reference genes among the 12 candidate reference genes were not revealed in the PA-1 cell line. Validation of the stability of the 12 investigated genes demonstrated that the incorrect selection of a reference gene resulted in a significant distortion of the gene expression profile in dormant cancer cells.

In this study, we demonstrate that mTOR signaling blockade can mitigate etoposide- or cisplatin-induced intestinal injury in mice. Importantly, although AZD8055 counteracts the side effects of chemotherapy drugs, it does not substantially affect their anti-tumor activity. Our study proposes the potential application of mTOR inhibitors as chemoprotective agents, presenting a means to prolong the duration of chemotherapy drug use and optimize the chemotherapeutic regimen.

The CETSA experiment demonstrated the existence of a favorable binding thermal stability between AZD-8055 and MYO1G. This research may identify potential biomarkers for predicting the prognosis of ESCC patients.
