Summary: The role of cyclins in hormone-dependent neoplasms, especially breast cancer, is crucial. However, cyclins in prostate cancer are less studied, particularly the role of other cyclins that requires further investigation. Recent studies have shown that cyclins not only regulate the cell cycle but also interact with other signaling pathways. The androgen signaling axis plays a significant role in prostate cancer progression and interferes with cyclin pathways.

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: This study analyzed data from male patients and found that the use of 5-alpha-reductase inhibitors (5-ARI) was associated with a lower risk of mortality, bladder instillation, and radical cystectomy in patients prior to the diagnosis of bladder cancer. The study suggests that the use of 5-ARI may reduce the risk of bladder cancer progression.

Summary: Stress-responsive microRNAs play a role in regulating cellular homeostasis and pathological processes, such as carcinogenesis, in response to environmental or dietary xenobiotics. The targets of carcinogenic mycotoxin-responsive miRNAs are associated with metabolism- or hormone-related diseases, including sex hormone-linked cancers. This study provides novel insights into the progression and intervention against adverse outcomes of human exposure to environmental oncogenic insults.

Summary: Glucocorticoids exert their effects by activating the glucocorticoid receptor (GR) throughout the body. This study investigated the interaction between glucocorticoids and androgen signaling in the liver transcriptome. The results showed that a substantial proportion of the hepatic transcriptome is androgen-dependent after chronic exposure, while the effects of glucocorticoids are largely androgen-independent after acute exposure. The study suggests that prolonged glucocorticoid exposure may upregulate androgen receptor expression, leading to androgen dependence not driven by direct interactions between the androgen receptor and glucocorticoid receptor.

Summary: Prostate cancer is the most frequently diagnosed non-cutaneous tumor in men in the Western world. Anti-androgens like bicalutamide are commonly used in therapy for non-organ confined prostate cancer. Cytokines, especially interleukins, can affect tumor cells' response to anti-androgens and more clinical trials are needed to improve this interaction.

Summary: This study demonstrates the association of androgen receptor with Filamin A in promoting migration and invasiveness of prostate cancer-derived cells, suggesting that targeting the AR/FlnA complex could improve the clinical management of invasive prostate cancer.

Summary: Obesity is a growing health challenge and is recognized as a risk factor for breast cancer. While the exact mechanisms linking obesity to breast cancer are not fully understood, this association has been linked to impaired hormone secretion by dysfunctional adipose tissue. Altered secretion of androgens and adipokines are independently associated with breast cancer development, highlighting the potential for crosstalk between these factors and the androgen receptor signaling in cancer cells. Understanding these interactions is crucial for guiding the development of new therapeutic approaches aimed at preventing and treating obesity and breast cancer.

Summary: This article reviews the challenges of breast cancer prevention and highlights the role of steroid hormones and their receptors in the development of the disease. It specifically focuses on the impact of androgens and their receptor on breast tissue and their correlation to breast cancer risk factors.

Summary: UHRF1 and CDC6, oncogenes that play critical roles in therapeutic resistance, are upregulated simultaneously in prostate cancer, where UHRF1 promotes CDC6 transcription controlled by AR through chromatin modification, contributing to anti-AR drug resistance and worse survival. Targeting both AR and UHRF1 simultaneously could be a novel and promising therapeutic approach for prostate cancer.

Summary: This study reveals that stromal AR inhibits prostate cancer progression by restraining secretory luminal cells, and deletion of stromal AR exacerbates tumor progression and leads to changes in the cellular state of secretory luminal cells.

Summary: Current clinical evidence suggests that antiandrogen therapy may have a beneficial effect on bladder tumors by reducing incidence and improving recurrence-free survival. However, there is significant variability in data sources and methodologies, as well as a lack of information on tolerability. Further prospective studies are needed to evaluate the therapeutic potential of these treatments.

Summary: This study compared prostate cancer detection on T-Bx and S-Bx and found that detection on T-Bx was associated with larger tumor volume and worse prognosis. However, simultaneous tumor detection on S-Bx in patients with prostate cancer on T-Bx did not have a significant clinicopathologic impact.

Summary: It is controversial whether Gleason grade should be assigned to intraductal carcinoma of the prostate (IDC-P) and if the prognostic value of comedonecrosis associated with IDC-P is equivalent to that in conventional/invasive prostatic adenocarcinoma (CPA) as a Gleason grade 5 pattern. This study evaluated radical prostatectomy findings and postoperative outcomes in 287 patients with CPA exhibiting any Gleason pattern 5. The presence of necrosis only in IDC-P was found to be associated with significantly worse oncologic outcomes, compared with necrosis only in CPA, suggesting that IDC-P necrosis should not be simply considered as a grade 5 pattern.

Summary: This study evaluated the clinical significance of intraoperative frozen section analysis (FSA) in patients with upper urinary tract cancer. The results showed that FSA can significantly reduce the risk of positive surgical margins in patients with ureteral tumors, but routine FSA for upper urinary tract cancer did not improve long-term oncologic outcomes significantly.

Summary: Quantification of perineural invasion on prostate biopsy showed significance as an independent predictor of prognosis, with multifocal perineural invasion and >1 perineural invasion per 10-mm tumor associated with worse outcomes after radical prostatectomy. Additionally, assigning points for multifocal perineural invasion improved the accuracy of predicting 5-year recurrence-free survival.

Summary: Androgen deprivation therapy is the main treatment for advanced prostate cancer, and relugolix has been developed as an oral alternative. Previous studies have shown comparable efficacy between relugolix and other gonadotropin-releasing hormone antagonists or agonists. This review summarizes the design, development, and therapeutic application of relugolix and discusses its potential as a promising oral alternative to injectable therapy.
