Downregulation of CASC15 attenuates the symptoms of polycystic ovary syndrome by affecting granulosa cell proliferation and regulating ovarian follicular development. Mol Cell Endocrinol 2024; 592:112322. [PMID: 38942281 DOI: 10.1016/j.mce.2024.112322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 06/23/2024] [Accepted: 06/24/2024] [Indexed: 06/30/2024]
Abstract
Polycystic ovary syndrome (PCOS) is a type of follicular dysplasia with an unclear pathogenesis, posing certain challenges in its diagnosis and treatment. Cancer susceptibility candidate 15 (CASC15), a long non-coding RNA closely associated with tumour development, has been implicated in PCOS onset and development. Therefore, this study aimed to investigate the molecular mechanisms underlying PCOS by downregulating CASC15 expression in both in vitro and in vivo models. We explored the potential regulatory relationship between CASC15 expression and PCOS by examining cell proliferation, cell cycle dynamics, cell autophagy, steroid hormone secretion capacity, and overall ovarian function in mice. We found that CASC15 expression in granulosa cells derived from patients with PCOS was significantly higher than those of the normal group (P < 0.001). In vitro experiments revealed that downregulating CASC15 significantly inhibited cell proliferation, promoted apoptosis, induced G1-phase cell cycle arrest, and influenced cellular autophagy levels. Moreover, downregulating CASC15 affected the follicular development process in newborn mouse ovaries. In vivo studies in mice demonstrated that disrupting CASC15 expression improved PCOS-related symptoms such as polycystic changes and hyperandrogenism, and significantly affected ovulation induction and embryo implantation in pregnant mice. Overall, CASC15 was highly expressed in granulosa cells of patients with PCOS and its downregulation improved PCOS-related symptoms by influencing granulosa cell function and follicular development in mice.

Association between genetic variants (rs920778, rs4759314, and rs217727) in LncRNAs and cervical cancer susceptibility in Chinese population: A systematic review and meta-analysis. Front Genet 2022; 13:988207. [PMID: 36313463 PMCID: PMC9608570 DOI: 10.3389/fgene.2022.988207] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 08/24/2022] [Indexed: 01/27/2024] Open
Abstract
Objective: The relationship between gene polymorphisms in long non-coding RNAs (LncRNAs) and cervical cancer susceptibility has been thoroughly analyzed; however, the conclusions are inconsistent. Therefore, this systematic review and meta-analysis aimed to accurately assess the relationship between them. Method: Eligible literatures were retrieved from PubMed, Medline, China National Knowledge Infrastructure (CNKI), and WanFang databases before 1 April 2022. The odds ratios with the corresponding 95% confidence intervals were used to evaluate the strength of these relationships. Sensitivity analysis for publication bias was conducted to assess the stability and reliability of included literatures. Results: A total of 59 SNPs in 11 LncRNAs were summarized for a systematic review in this study, and then, a meta-analysis of rs920778 and rs4759314 polymorphisms in HOTAIR and rs217727 polymorphisms in H19 was conducted. The results demonstrated that rs920778 and rs4759314 polymorphisms were significantly correlated with cervical cancer susceptibility. Further subgroup analysis of rs920778 polymorphism showed that both small sample size and large sample size subgroups were associated with cervical cancer susceptibility. However, no association was found between rs217727 polymorphism and cervical cancer risk in all five genetic models. Conclusion: In conclusion, the rs4759314, rs920778, and rs217717 polymorphisms of HOTAIR and H19 may be associated with cervical cancer. However, the results should be interpreted with caution due to the limited sample and heterogeneity in this study. Large-scale and well-designed studies need to be practiced to validate our results.

Abstract
BACKGROUND CASC15, one of long non-coding RNA, is involved in the regulation of many tumor biological processes, and is expected to become a new biological therapeutic target. This paper aims to elucidate the pathophysiological function of CASC15 in various tumors. METHODS The relationship between CASC15 and tumors was analyzed by searching references, and summarized the specific pathophysiological mechanism of CASC15. RESULTS LncRNA CASC15 is closely related to tumor development, and has been shown to be abnormally high expressed in all kinds of tumors, including breast cancer, cervical cancer, lung cancer, hepatocellular carcinoma, gastric cancer, bladder cancer, colon cancer, colorectal cancer, cardiac hypertrophy, intrahepatic cholangiocarcinoma, leukemia, melanoma, tongue squamous cell carcinoma and nasopharyngeal carcinoma. However, CASC15 has been found to be down-expressed abnormally in ovarian cancer, glioma and neuroblastoma. Besides, it is identified that CASC15 can affect the proliferation, invasion and apoptosis of tumors. CONCLUSION LncRNA CASC15 has the potential to become a new therapeutic target or marker for a variety of tumors.

Abstract
INTRODUCTION Breast cancer (BC) is a prevalent malignant tumor among women. Numerous studies have been reported that long noncoding RNAs (lncRNAs) were associated with various human diseases. MATERIALS AND METHODS In the current study, 681 patients with BC and 680 unrelated controls were recruited to investigate the correlation between lncRNA cancer susceptibility candidate 15 (CASC15) polymorphisms and BC risk in Chinese Han women. We performed single-nucleotide polymorphism genotyping using the Agena MassARRAY platform. The relationship between lncRNA CASC15 polymorphisms and the risk of BC were evaluated through odds ratios and 95% confidence intervals. RESULTS Our results suggested that the lncRNA CASC15 rs7740084 "G/G" genotype and rs1928168 "T/C" genotype significantly reduced BC risk in different genetic models (P = .045, P = .029, and P = .047, respectively). However, rs9393266 "C/T" and "C/T-T/T" genotypes were correlated with the risk of BC (P = .021 and P = .048). In addition, we also observed that rs1928168 was related to the risk of BC in patients with age > 50 years (P = .025), body mass index > 24 (P = .006), and tumor size (P = .035). For rs9393266, it was revealed that the "C/T" and "C/T-T/T" genotypes were related to BC risk in people with age ≤ 50 years (P = .005) and body mass index > 24 (P = .023). CONCLUSION In summary, our results revealed a potential interaction between lncRNA CASC15 polymorphisms and BC susceptibility. The results provided an important insight into lncRNA CASC15 function in the development of BC.

Abstract
Background Cervical cancer is a frequent, common cancer in women, and causes high cancer‐related deaths among women in our world. Accumulating studies provided an important evidence for long noncoding RNA (lncRNA) polymorphisms in the susceptibility of various cancer. Here, we recruited 494 cervical cancer cases and 504 unrelated controls to assess the relationship between CASC15 (OMIM# 616610) polymorphisms and cervical cancer susceptibility. Methods Agena MassARRAY platform was conducted to genotype CASC15 polymorphisms. Odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed through logistic regression to adjust for confounding factors, such as age and gender. Results Our study suggested that rs12212674 (NC_000006.12:g.22086845T>A) “A” allele was significantly associated with an increased risk of cervical cancer (OR = 1.31, 95% CI = 1.01–1.69, p = .041). The result was demonstrated in the log‐additive model (OR = 1.32, 95% CI = 1.02–1.72, p = .037). After age stratification, we also found that the “TT” genotype of rs4712653 (NC_000006.11:g.22125964T>C) in CASC15 was interaction with a higher cervical cancer risk in subjects aged ≤51 years in the co‐dominant model (OR = 2.08, 95% CI = 1.02–4.25, p = .044) and the recessive model (OR = 2.11, 95% CI = 1.05–4.24, p = .036). Whereas no significant correlation was found among other SNPs of CASC15 polymorphisms and the risk of cervical cancer. MDR analysis illustrated that the interaction between rs7740084 (NC_000006.11:g.21727531G>A), rs1555529 (NC_000006.11:g.21691704A>G), and rs12212674 had a certain effect on the progress of cervical cancer. Conclusion Our results revealed a potential interaction between CASC15 polymorphisms and cervical cancer susceptibility. The results provided important insights into CASC15 function in the development of cervical cancer.
