Prostate Cancer From a Sex and Gender Perspective: A Review

Computational Identification and Validation of Metabolic Cell Death-Related Prognostic Biomarkers for Personalized Treatment Strategies in Prostate Cancer

Prostate cancer (PCa) is a prevalent malignancy characterized by metabolic dysregulation and varied prognosis. Identifying prognostic biomarkers related to metabolic cell death could enhance risk stratification and treatment strategies. The purpose of this study was to identify prognostic genes associated with metabolic cell death in PCa and formulate a risk model for improved patient stratification. We identified genes that exhibit differential expression in The Cancer Genome Atlas Prostate Adenocarcinoma (TCGA-PRAD) cohort (n = 394), with validation using GSE70769 (n = 92) and RT-qPCR on tissue samples from 5 patients. Candidate genes were intersected with metabolic cell death-related genes to identify prognostic markers. Independent prognostic factors were determined utilizing univariate and multivariate Cox regression analyses (p < 0.05, HR ≠ 1). A nomogram was designed, and the validation of gene expression was carried out using RT-qPCR on tissue samples from five PCa patients. A total of 78 candidate genes were identified, with ASNS and ZNF419 emerging as independent prognostic factors. The gene-based risk model successfully stratified patients into high- and low-risk groups, demonstrating correlations with overall survival and clinicopathological features, while also revealing significant differences in immune cell infiltration patterns through immune microenvironment analysis. Additionally, somatic mutation analysis indicated TP53, TTN, and SPOP as frequently mutated genes. This study identifies ASNS and ZNF419 as novel prognostic biomarkers in PCa, contributing to improved risk stratification and personalized treatment strategies. Further investigation into their functional roles may provide insights into therapeutic targets for PCa management.

Exploring NUP62's role in cancer progression, tumor immunity, and treatment response: insights from multi-omics analysis

Background

NUP62, a key component of the nuclear pore complex, is closely associated with cellular functions and cancer progression. However, its expression patterns, prognostic value, and relationship with tumour immunity and drug sensitivity across multiple cancers have not been systematically studied. This study used multi-omics analyses combined with experimental validation in gastric cancer to investigate the expression, functional characteristics, and clinical relevance of NUP62 in cancer.

Methods

Data from TCGA, GTEx, and CPTAC databases were used to analyse the expression, mutation characteristics, and clinical associations of NUP62. Tools such as SangerBox, TIMER 2.0, and GSEA were employed to evaluate the relationship between NUP62 and the tumour immune microenvironment, as well as its involvement in signalling pathways. Immunohistochemistry and RT-PCR were used to validate the expression of NUP62 in gastric cancer tissues. PRISM and CTRP databases were utilised to assess the correlation between NUP62 expression and drug sensitivity.

Results

NUP62 was significantly upregulated in multiple cancers and was associated with poor prognosis in cancers such as clear cell renal carcinoma (KIRC), lower-grade glioma (LGG), and adrenocortical carcinoma (ACC), while playing a protective role in others, such as bladder cancer (BLCA) and stomach cancer (STAD). Functional analyses showed that NUP62 is involved in cell cycle regulation, DNA damage repair, and tumour immunity. High NUP62 expression was significantly correlated with increased infiltration of immune cells, such as macrophages and T cells, and a higher response rate to immunotherapy. Drug sensitivity analysis identified NUP62 as a marker of sensitivity to various chemotherapeutic agents. Validation experiments demonstrated that NUP62 mRNA and protein levels were significantly higher in gastric cancer tissues than in adjacent normal tissues.

Conclusions

NUP62 plays a critical role in multiple cancers and shows potential as a biomarker for cancer diagnosis, prognosis, and therapeutic response prediction. Its role in tumour immunity and signalling pathways highlights its potential as a target for immunotherapy and precision medicine.

A Practical Guide to Avoiding Biased Communication in Reproductive Biology

When cultural biases pervade communication, whether visual or text-based, objectivity is impaired. Anthropocentrism (human-centered bias) and androcentrism (male-centered bias) in particular distort perspectives in mammalian reproductive biology. This paper provides a resource for professionals who understand how cultural biases can be reinforced with language, visuals, and conceptual framing. After brief explanations, we present neutral alternatives to biased terminology as well as ways to avoid bias in illustrations. Since this paper is animal-centric, we hope to inspire the creation of similar resources across a more diverse biota and, thus, move towards a more neutral perspective across reproductive biology.

Theorising masculinity, ageing, and the lived body: the case of prostate cancer

This article conceptualises how masculinity and masculine ideals are played out in relation to prostate cancer treatment and its side-effects, offering a heuristic and theoretical perspective with which to make sense of the complex interrelationship between lived gendered bodies and social structures. With the support of three case studies of older men treated for prostate cancer, the article explores how the concept of hegemonic masculinity can be used to analyse the ill and ageing body. A phenomenologically informed approach to the body, which illustrates how masculinity is lived and experienced through certain body schemas, is used. The three case studies show variation in how masculinity is enacted and embodied, illustrating actions to (1) restore and maintain masculinity through phallic experience; (2) reconstruct masculinity by connecting bodily experience to notions of the ageing and a less potent body; and (3) to counter narrowly defined notions of masculinity by dissociating or decoupling masculinity from ideals of potency and performance. With the help of the case studies, the strategies identified, and the fluidity and dynamism of the concept of hegemonic masculinity, findings reveal how inequalities between men and women are produced and maintained, in and through bodily experience, and diverse body schemas.

Men's Achilles' heel: prostate cancer and the reconstruction of masculinity

The aim of this study was to investigate how Swedish men diagnosed with prostate cancer understand the effects of their treatment in relation to sexual health and masculinity. Utilising a phenomenological and sociologically informed approach, the study involved interviews with 21 Swedish men who experienced problems following treatment. The results showed that participants' initial response post-treatment, involved the development of new bodily understandings and socially informed strategies to handle incontinence and sexual dysfunction. Due to impotence and the loss of ejaculatory ability following treatments such as surgery, participants re-articulated the meaning of intimacy, as well as their understanding of masculinity and themselves as ageing men. Unlike in previous research, such a re-articulation of masculinity and sexual health is understood as taking place within rather than in opposition to hegemonic masculinity.

Care needs of Japanese men for sexual dysfunction associated with prostate cancer treatment

PURPOSE

Prostate cancer (PC) treatment causes sexual dysfunction (SD) and alters fertility, male identity, and intimate relationships with partners. In Japan, little attention has been paid to the importance of providing care for SD associated with PC treatment. This study is aimed at clarifying the care needs of Japanese men regarding SD associated with PC treatment.

METHODS

One-to-one semi-structured interviews were conducted with 44 PC patients to identify their care needs. Data were analyzed using thematic analysis.

RESULTS

Four core categories emerged from the analysis. (1) "Need for empathy from medical staff regarding fear of SD": patients had difficulty confiding in others about their sexual problems, and medical staff involvement in their SD issues was lacking. (2) "Need for information that provides an accurate understanding of SD and coping strategies before deciding on treatment": lack of information about SD in daily life and difficulty understanding information from medical institutions, caused men to regret their treatment. (3) "Need for professional care for individuals and couples affected by SD": men faced loss of intimacy because of their partners' unwillingness to understand their SD issues or tolerate non-sexual relationships. (4) "Need for an environment that facilitates interaction among men to resolve SD issues": men felt lonely and wanted to interact with other patients about their SD concerns.

CONCLUSION

These findings may help form care strategies tailored to these needs and applicable to other societies with strong traditional gender norms.

Prostate cancer awareness among transgender women after gender-affirming surgery

BACKGROUND

The prostate gland remains unresected during gender-affirming surgery (GAS) for transgender women (TGW), and may develop malignancies in later life. We sought to evaluate prostate cancer awareness (PCA) among post-GAS TGW.

METHODS

The investigators implemented a cross-sectional study and enrolled a sample of Thai post-GAS TGW without medical background. Predictor variables were categorized as demographic, clinical, operative, or postoperative. The outcome variable was PCA (yes/no). Appropriate statistics were computed, and a p-value ≤ 0.05 was considered statistically significant.

RESULTS

The sample consisted of 100 Thai post-GAS TGW (4% bisexual, 12% bachelor [or higher] graduates, 51% service workers, 64% had monthly net income <40,000 TB [or ca. 1050 Euro], 92% operated by plastic surgeons) with a mean age of 26.2 ± 5.4 years (range: 18-45). On bivariate analysis, PCA was significantly associated with educational level (p = 0.007; adjusted odd ratio [ORadj. ]: 5.85; 95% confidence interval [95% CI]: 1.65-20.69), being operated ≥ 10 years  (p = 0.01; ORadj. : 0.16; 95% CI: 0.04-0.76), self-recognition of the remaining prostate gland (p = 0.0001; ORadj. : 0.02; 95% CI: 0-0.12), and emphasis on PCA by the GAS operator (p = 0.01; ORadj. : 0.07; 95% CI: 0.01-0.63). Multiple linear regression analysis revealed a statistically significant, positive correlation (r = 0.78; p = 0.0001) among these four predictors, and continued to confirm the positive effect on PCA in TGW with high education and realization of the prostate gland (r = 0.56; p = 0.04) or information on PCA by the operator (r = 0.68; p = 0.003).

CONCLUSION

The GSA operator should intensively inform TGW about the remnant prostate and the risk of PC, especially those with low and middle levels of education attained.
