Castration-resistant prostate cancer (CRPC) marks the advanced phase of prostate malignancy, manifested through two principal subtypes: castration-resistant adenocarcinoma (CRPC-adeno) and neuroendocrine prostate cancer (NEPC). This study aims to identify unique central regulatory genes, assess the immunological landscape, and explore potential therapeutic strategies specifically tailored to NEPC. We discovered 1444 differentially expressed genes (DEGs) distinguishing between the two cancer types and identified 12 critical hub genes. Notably, CHST1, MPPED2, and RIPPLY3 emerged as closely associated with the immune cell infiltration pattern, establishing them as top candidates. Prognostic analysis highlighted the potential critical roles of CHST1 and MPPED2 in prostate cancer development, findings corroborated through in vitro and in vivo assays. Moreover, we validated the functions and expression levels of CHST1, MPPED2, and RIPPLY3 in NEPC using cell lines, animal models and human tissues. In the final step, we found that imatinib might be the drug specific to NEPC, which was further confirmed by in vitro cell assay. Our results revealed the clinical characteristics, molecular features, immune cell infiltration pattern in CRPC-adeno and NEPC, and identified and confirmed CHST1, MPPED2, and RIPPLY3 as the critical genes in the development in prostate cancer and NEPC. We also predicted and validated imatinib as the potential specific drugs to NEPC.

Refractive error (RE) and myopia are complex polygenic conditions with the majority of genome-wide associated genetic variants in non-exonic regions. Given this, and the onset during childhood, gene-regulation is expected to play an important role in its pathogenesis. This prompted us to explore beyond traditional gene finding approaches. We performed a genetic association study between variants in non-coding RNAs and enhancers, and RE and myopia. We obtained single-nucleotide polymorphisms (SNPs) in microRNA (miRNA) genes, miRNA-binding sites, long non-coding RNAs genes (lncRNAs) and enhancers from publicly available databases: miRNASNPv2, PolymiRTS, VISTA Enhancer Browser, FANTOM5 and lncRNASNP2. We investigated whether SNPs overlapping these elements were associated with RE and myopia leveraged from a large GWAS meta-analysis (N = 160,420). With genetic risk scores (GRSs) per element, we investigated the joint effect of associated variants on RE, axial length (AL)/corneal radius (CR), and AL progression in an independent child cohort, the Generation R Study (N = 3638 children). We constructed a score for biological plausibility per SNP in highly confident miRNA-binding sites and enhancers in chromatin accessible regions. We found that SNPs in two miRNA genes, 14 enhancers and 81 lncRNA genes in chromatin accessible regions and 54 highly confident miRNA-binding sites, were in RE and myopia-associated loci. GRSs from SNPs in enhancers were significantly associated with RE, AL/CR and AL progression. GRSs from lncRNAs were significantly associated with all AL/CR and AL progression. GRSs from miRNAs were not associated with any ocular biometric measurement. GRSs from miRNA-binding sites showed suggestive but inconsistent significance. We prioritized candidate miRNA binding sites and candidate enhancers for future functional validation. Pathways of target and host genes of highly ranked variants included eye development (BMP4, MPPED2), neurogenesis (DDIT4, NTM), extracellular matrix (ANTXR2, BMP3), photoreceptor metabolism (DNAJB12), photoreceptor morphogenesis (CHDR1), neural signaling (VIPR2) and TGF-beta signaling (ANAPC16). This is the first large-scale study of non-coding RNAs and enhancers for RE and myopia. Enhancers and lncRNAs could be of large importance as they are associated with childhood myopia. We provide a confident blueprint for future functional validation by prioritizing candidate miRNA binding sites and candidate enhancers.

Introduction Recently, the expression of metallophosphoesterase-domain-containing protein 2 (MPPED2) was identified in cervical cancer. However, its precise role and correlation with other tumor suppressor proteins, such as p16INK4A, is not well studied in high-risk human papillomavirus (HPV) integrated human cervical carcinoma. Hence, in the present study, we try to see the expression of MPPED2 in human cervical carcinoma and its correlation with age and p16INK4A protein expression level. Methods The prospective study consists of 200 samples of 150 known cervical carcinoma and 50 controls. Histopathological evaluation, immunohistochemical staining, and semi-quantitative scoring of the intensity of proteins were performed. Statistical analysis was performed with the Shapiro-Wilk test, Spearman's rho correlation sig. (two-tailed), and Student's t-test. Results The data show that among the 150 cases, 136 (68.0%) cervical carcinoma tissues express the presence of high-risk HPV viral genome integration in the host cell. The expression of p16INK4A protein is higher in those tissues identified with high-risk HPV viral genomes. In contrast, the expression of MPPED2 protein is lesser or absent in those cervical tissues that have the higher expression of p16INK4A protein and vice versa. There is a significant correlation (p=0.000) between age and p16INK4A protein expression but not with MPPED2. A significant linear correlation (p=0.000) is found between the p16INK4A and MPPED2 proteins. Conclusion It may support the therapeutic application of MPPED2 protein to prevent cervical carcinoma progression in the near future.
