The low-risk group exhibited improved survival outcomes and increased sensitivity to immunotherapy, whereas the high-risk group showed heightened sensitivity to to bexarotene, bicalutamide, embelin, FH535, and pazopanib. Quantitative PCR results indicated that ILF3-DT and PPP1R14B-AS1 were downregulated in CC tissues, whereas RUSC1-AS1 was upregulated. In conclusion, we developed a novel prognostic risk signature based on 9 disulfidptosis-related lncRNAs, which may serve as an independent predictor of immunotherapy response and chemotherapy sensitivity in CC.
Flow cytometry evaluated immune infiltration in bicalutamide-treated mice, and anti-PD1 was combined with degarelix/bicalutamide in preclinical mouse model. NHT enhances TLS formation, maturation, and immune cell infiltration, suggesting a synergistic role for androgen deprivation in shaping the tumor immune microenvironment. The improved anti-tumor response with combined anti-PD1 and ADT highlights the potential of immunotherapy-endocrine therapy combinations as a promising treatment strategy for PCa.
Additionally, a microbial prognostic-predictive signature was established comprising Succinimonas, Collimonas, and Marichromatium, which also exhibited potential for indicating immunotherapeutic benefit and predicting drug sensitivity to cisplatin, cytarabine, pyrimethamine, olaparib, bicalutamide and vorinostat in LUAD treatment. This study identified intratumoral microbes associated with metabolism, revealed distinct subtypes and their roles in LUAD, and established a predictive signature for the prognosis and therapeutic responsiveness of LUAD.
Our study screened seven genes with potential value for predicting long-term survival of patients with PCa and developed a prognostic model. These findings are expected to guide future development of effective therapies.
Sensitivity analysis of 60 chemotherapy agents indicated that Bicalutamide was more effective in LRG, while ATRA, CCT018159, PHA-665752, and PLX4720 demonstrated greater efficacy in HRG. RT-qPCR validation confirmed upregulation of CDK4 and downregulation of CFLAR in ALL samples (P < 0.05). This study offers important theoretical support for the prognostic evaluation and personalized treatment strategies in ALL.
Direct AR antagonists (apalutamide, bicalutamide) produced greater TMPRSS2 suppression than Gonadotropin-Releasing Hormone modulators or androgen biosynthesis inhibitors. Our findings demonstrate that ADT significantly reduces pulmonary TMPRSS2 expression, with direct AR antagonists showing the strongest effect. This suggests a potential mechanistic explanation for differential COVID-19 susceptibility and provides a rationale for investigating AR-targeted therapies as potential protective interventions against SARS-CoV-2 infection severity.

49 male rats were used in this experiment and PCa was induced in 35 rats by successive administration of bicalutamide(oral), testosterone(subcutaneous) and benzo(a)pyrene(intraprostatic), except those in the sham operated and pharmacological group...No major signs of toxicity were observed throughout the experiment. No significant variation in the masses of the liver, spleen, ALAT and activities as well as creatinine levels were observed.
PRR22 is a novel, independent prognostic biomarker and actionable therapeutic target in PRAD, linking tumor aggressiveness to immune microenvironment remodeling and drug resistance. These findings establish PRR22 as a candidate for clinical implementation in risk stratification and targeted therapy.
