Summary: Dogs naturally develop prostate cancer similar to aggressive forms found in humans. Prostate cancer samples in dogs often lack androgen receptor (AR), which can enhance our understanding of AR-indifferent prostate cancer in humans. This review highlights the molecular similarities between dog and human prostate cancer variants, suggesting the potential use of dogs as pre-clinical animal models for developing new therapies and diagnostics that can benefit both species.

Summary: EZH2 has been shown to promote the development of castration-resistant prostate cancer (CRPC) by interacting with the androgen receptor (AR) to reprogram its transcriptional activity, facilitating the transition of CRPC into a lineage infidelity state.

Summary: Androgen deprivation therapy (ADT) is the standard care for advanced prostate cancer patients. B7-H3 is a promising new target for PCa immunotherapy. The expression pattern of B7-H3 following ADT and during CRPC progression is largely unknown but critically important for identifying patients and determining the optimal timing of B7-H3 targeting immunotherapy.

Summary: Abnormal expression of ISL1 has been closely associated with cancer development and progression, with particular focus on its role in the androgen receptor-dependent prostate cancer cell growth, EMT, and enzalutamide resistance. ISL1 knockdown was found to inhibit AR activity, cell growth, and EMT in enzalutamide-resistant cells, suggesting its potential as a therapeutic target for CRPC. The study highlights the importance of downregulating ISL1 expression to overcome enzalutamide resistance and improve survival in CRPC patients.

Summary: Recent research has highlighted the important role of the androgen receptor (AR) in prostate cancer, particularly in castration-resistant prostate cancer. While new AR signaling-targeted agents have been developed to inhibit AR activity, long-term use may lead to the emergence of AR-independent prostate cancer cells, which pose a challenge for effective treatment options. Further studies are needed to address the transformation mechanisms and potential treatment strategies for AR-independent prostate cancer.

Summary: The androgen receptor (AR) plays a crucial role in the development and progression of prostate cancer (PCa), and treatment for hormone-sensitive prostate cancer (HSPC) relies heavily on androgen deprivation therapy (ADT). Despite most patients progressing to castration-resistant prostate cancer (CRPC), studies suggest that manipulating alternative molecular pathways can help improve current treatments and develop novel therapies for CRPC management.

Summary: SBI-46, an antiandrogen and histone deacetylase inhibitor, demonstrates anticancer effects on castration-resistant prostate cancer (CRPC) by downregulating the expression of AR and AR-splice variants. It induces apoptosis by activating pro-apoptotic genes and inhibiting anti-apoptotic genes. Additionally, oral administration of SBI-46 suppresses the growth of CRPC xenograft tumors expressing AR or both AR and AR-SV.

Summary: The study identifies B7-H3 as an immune checkpoint overexpressed in prostate cancer, particularly in metastatic castration-resistant prostate cancer (mCRPC). Enzalutamide-resistant mCRPC cells show increased expression of B7-H3, and it is associated with resistance signaling pathways. The gene network of B7-H3 is strongly correlated with androgen receptor (AR) and its co-factors, suggesting potential therapeutic targets for mCRPC.

Summary: Androgens are crucial in the development of prostate cancer, and targeting steroidogenesis and the androgen receptor has been effective in delaying disease progression. New generation androgen receptor pathway inhibitors like abiraterone and enzalutamide continue to emphasize the role of the androgen-AR axis, even in cases of resistance. The importance of this axis in managing the disease after resistance to current treatments, particularly in neuroendocrine prostate cancer, remains uncertain.

Summary: This study examines the impact of AR gene mutations on resistance to Enzalutamide using structural bioinformatics and molecular simulation methods. The mutations alter the binding mode of Enzalutamide, disrupting the antagonist activity by misstargeting key residues. These findings provide a structural basis for understanding resistance mechanisms and designing effective drugs.

Summary: The study identified BCT as a potent inhibitor targeting both AR-FL and AR-V7 activities in CRPC, effectively suppressing tumor growth and metastasis. Mechanistically, BCT disrupts the interaction of HSP90 with AR-FL/AR-V7, leading to their degradation and showing promising therapeutic potential against CRPC.

Summary: Metastatic prostate cancer is the most common cancer in males with a poor prognosis, and many patients develop the AR-V7 variant. AR-V7 acts as a transcription factor in the nucleus, repressing crucial tumor suppressor genes. Anti-AR-V7 drugs show promise for this subset of patients.
