Abstract
Two classes of non-coding RNAs, namely lncRNAs and miRNAs have been reported to be involved in the pathogenesis of varicocele. MIR210HG, MLLT4-AS1, gadd7, and SLC7A11-AS1 are among lncRNAs whose expression has been changed in patients with varicocele in association with the sperm quality. Animal studies have also suggested contribution of NONRATG001060, NONRATG002949, NONRATG013271, NONRATG027523 and NONRATG023747 lncRNAs in this pathology. Meanwhile, expression of some miRNAs, such as miR-210-3p, miR-21, miR-34a, miR-122a, miR-181a, miR-34c and miR-192a has been altered in this condition. Some of these transcripts have the potential to predict the sperm quality. We summarize the impacts of lncRNAs and miRNAs in the pathogenesis of varicocele.

Banerjee S, Sarkar R, Mukherjee A, Mitra S, Gope A, Chawla-Sarkar M. Rotavirus-induced lncRNA SLC7A11-AS1 promotes ferroptosis by targeting cystine/glutamate antiporter xCT (SLC7A11) to facilitate virus infection. Virus Res 2024; 339:199261.

Abstract
Rotavirus (RV) is the primary etiological agent of virus-associated gastroenteritis in infants, causing 200,000 childhood death annually. Despite the availability of vaccines, rotaviral diarrhea continues to be a severe issue in underdeveloped nations in Asia and Africa. The situation demands continual studies on host-rotavirus interactions to understand disease pathogenesis and develop effective antiviral therapeutics. Long non-coding RNAs (lncRNAs), which are a subset of non-coding RNAs of more than 200 nucleotides in length, are reported to play a regulatory function in numerous viral infections. Virus infection often alters the host transcriptome including lncRNA that are differentially expressed either to play an antiviral role or to be advantageous towards virus propagation. In the current study, qPCR array-based expression profiling of host lncRNAs was performed in rotavirus-infected HT-29 cells that identified the lncRNA SLC7A11-AS1 to be upregulated during RV infection. Knockdown of SLC7A11-AS1 conspicuously reduced RV titers implying its pro-viral significance. RV-induced SLC7A11-AS1 downregulates the gene SLC7A11/xCT that encodes the light chain subunit of the system XC- cystine-glutamate exchange transporter, leading to decrease in intracellular glutathione level and increase in lipid peroxidation, which are signature features of ferroptotic pathway. Ectopic expression of xCT also abrogated RV infection by reversing the virus optimized levels of intracellular GSH and lipid ROS levels. Cumulatively, the study reveals that RV infection triggers ferroptotic cell death via SLC7A11-AS1/xCT axis to facilitate its own propagation.

Abstract
Male infertility is a complex disorder affecting many couples worldwide. Long noncoding RNAs (lncRNAs) regulate important cellular processes; however, a comprehensive understanding of their role in male infertility is limited. This systematic review investigates the differential expressions of lncRNAs in male infertility or variations in lncRNA regions associated with it. The PRISMA guidelines were used to search Pubmed and Web of Science (1 June 2022). Inclusion criteria were human participants, patients diagnosed with male infertility, and English language speakers. We also performed an in silico analysis investigating lncRNAs that are reported in many subtypes of male infertility. A total of 625 articles were found, and after the screening and eligibility stages, 20 studies were included in the final sample. Many lncRNAs are deregulated in male infertility, and interactions between lncRNAs and miRNAs play an important role. However, there is a knowledge gap regarding the impact of variants found in lncRNA regions. Furthermore, eight lncRNAs were identified as differentially expressed in many subtypes of male infertility. After in silico analysis, gene ontology (GO) and KEGG enrichment analysis of the genes targeted by them revealed their association with bladder and prostate cancer. However, pathways involved in general in tumorigenesis and cancer development of all types, such as p53 pathways, apoptosis, and cell death, were also enriched, indicating a link between cancer and male infertility. This evidence, however, is preliminary. Future research is needed to explore the exact mechanism of action of the identified lncRNAs and investigate the association between male infertility and cancer.

Abstract
Varicoceles (VCs) have received widespread attention as a primary factor affecting male fertility and a pathological condition that may lead to decreased sperm count and motility in patients. Many studies have shown that an imbalance of local antioxidant balance exists in patients with VC, leading to an obvious increase in the content of reactive oxygen species (ROS) and may cause reductive stress. Excessive ROS may aggravate spermatogenesis dysfunction and affect male fertility. Poly(ADP-ribose) polymerase (PARP) is an enzyme associated with DNA repair in eukaryotic cells, can be activated by DNA fragments with structural damage, and has been considered a DNA damage receptor in DNA damage repair and apoptosis. We built a rat model of VC and an oxidative damage model of a spermatocyte-derived cell line (GC-2 cells) induced by hydrogen peroxide to study the role of PARP1 in VC. Differentially expressed genes (DEGs) were obtained by RNA sequencing in the testes of VC rats. Analysis of DEGs revealed some genes with significantly altered expression, which were validated in rat and cell models. Immunofluorescence, real-time quantitative PCR analysis, Western blot, and flow cytometry were used to analyze the changes between the control group and the VC or hydrogen peroxide group. Overall, we found that PARP1 protein expression increased in VC rats and in the hydrogen peroxide-induced oxidative stress model of GC-2 cells. Parthanatos may be one of the factors leading to reduced reproductive capacity in VC patients. Our study provides novel insights into the mechanisms of male infertility induced by oxidative stress and provides a new therapeutic target for VC.

Analysis of the lncRNA-Associated Competing Endogenous RNA (ceRNA) Network for Tendinopathy. Genet Res (Camb) 2022; 2022:9792913.

Abstract
Background We aimed to construct the lncRNA-associated competing endogenous RNA (ceRNA) network and distinguish feature lncRNAs associated with tendinopathy. Methods We downloaded the gene profile of GSE26051 from the Gene Expression Omnibus (GEO), including 23 normal samples and 23 diseased tendons. Differentially expressed mRNAs (DEmRNAs) and differentially expressed lncRNAs (DElncRNAs) were identified, and functional and pathway enrichment analyses were performed. Protein-protein interaction (PPI) network was constructed and further analyzed by module mining. Moreover, a ceRNA regulatory network was constructed based on the identified lncRNA–mRNA coexpression relationship pairs and miRNA–mRNA regulation pairs. Results We identified 1117 DEmRNAs and 57 DElncRNAs from the GEO data. The downregulated DEmRNAs were particularly associated with muscle contraction and muscle filament, while the upregulated ones were linked to extracellular matrix organization and cell adhesion. From the PPI network, 11 modules were extracted. Genes in MCODE 2 (such as TPM4) were significantly involved in cardiomyopathy, and genes in MCODE 4 (such as COL4A3 and COL4A4) were involved in focal adhesion, ECM-receptor interaction, and PI3K-Akt signaling pathway. The ceRNA network contained 7 lncRNAs (MIR133A1HG, LINC01405, PRKCQ-AS1, C10orf71-AS1, MBNL1-AS1, HOTAIRM1, and DNM3OS), 63 mRNAs, and 41 miRNAs. Downregulated lncRNA MIR133A1HG could competitively bind with hsa-miR-659-3p and hsa-miR-218-1-3p to regulate the TPM3. Meanwhile, MIR133A1HG could competitively bind with hsa-miR-1179 to regulate the COL4A3. Downregulated C10orf71-AS1 could competitively bind with hsa-miR-130a-5p to regulate the COL4A4. Conclusions Seven important lncRNAs, particularly MIR133A1HG and C10orf71-AS1, were found associated with tendinopathy according to the lncRNA-associated ceRNA network.

Abstract
Resistance to platinum-based chemotherapy is a major obstacle in gastric cancer (GC) treatment. Abundant long noncoding RNAs (lncRNAs) are reported to play important roles in tumorigenesis and drug resistance biology. Herein, we report that the SLC7A11-AS1 and xCT are involved in cisplatin resistance in GC. SLC7A11-AS1 was downregulated and xCT was upregulated in cisplatin-resistant GC tissues and cell lines. GC patients with low expression of SLC7A11-AS1 and high expression of xCT had a poor prognosis and relatively poor response to chemotherapy. Overexpression of SLC7A11-AS1 weakened GC growth, reduced intracellular GSH biosynthesis, enhanced intracellular reactive oxygen species (ROS) and conferred sensitivity to cisplatin to resistant GC cells in vitro and in vivo. Mechanistically, SLC7A11-AS1 directly suppressed xCT expression, while miR-33a-5p remarkably reduced SLC7A11-AS1 and xCT expression by directly targeting the SLC7A11-AS1 and xCT 3'UTRs. In addition, we found that low SLC7A11-AS1 expression activated the p38MAPK-JNK signaling pathway, and increased the expression of cisplatin export gene ATP7A and the GSH biosynthesis gene GCLM in GC.

Abstract
Motility and morphology are two important characteristics of a fertile spermatozoon. CFAP44 gene encodes flagellar protein 44 involved in the formation and function of the flagella and cilia. Long non-coding RNAs are regulatory elements involved in several processes, including reproduction. We aimed to study the alterations in the expressions of CFAP44 and CFAP44-AS1 genes in infertile men with asthenozoospermia and terato-asthenozoospermia. In this case-control study, a total of 105 subjects, including 35 TAZ patients, 34 AZ patients and 35 normozoospermic men, were enrolled. After RNA extraction from spermatozoa samples, quantitative real-time PCR was performed to compare the expression of CFAP44 and CFAP44-AS1 between the studied groups. A meaningful reduction in CFAP44 expression and a significant reduction in the expression of CFAP44-AS1 were observed. Moreover, a positive correlation between both genes' expressions and normal sperm morphology was detected in NZ, AZ and TAZ groups. Also, there was a positive relation between CFAP44 gene expression and sperm motility in AZ and TAZ groups. The expression of CFAP44-AS1 was positively correlated with sperm motility and morphology. Present results confirm the role of CFAP44 and CFAP44-AS1 in the motility and morphology of spermatozoon, and deregulation of these genes may contribute to male infertility.

Abstract
Objectives To evaluate the expression, potential functions and mechanisms of long noncoding RNAs (lncRNAs) in the pathogenesis of varicocele (VC)‐induced spermatogenic dysfunction. Materials and Methods We established a rat model with left experimental VC and divided rats into the sham group, the VC group, and the surgical treatment group (each group, n = 10). Haematoxylin and eosin (HE) staining and sperm quality were analysed to evaluate spermatogenesis function. LncRNA expression profiles were analysed using lncRNA‐Seq (each group n = 3) and validated using quantitative real‐time polymerase chain reaction (each group n = 10). Correlation analysis and gene target miRNA prediction were used to construct competing endogenous RNA network. The regulated signalling pathway and spermatogenic dysfunction of differentially expressed lncRNAs (DE lncRNAs) were validated by Western blot. Results HE detection and sperm quality analysis showed that VC could induce spermatogenic dysfunction. Eight lncRNAs were upregulated and three lncRNAs were downregulated in the VC group compared with the sham group and surgical treatment group. The lncRNA of NONRATG002949.2, NONRATG001060.2, NONRATG013271.2, NONRATG022879.2, NONRATG023424.2, NONRATG005667.2 and NONRATG010686.2 were significantly negatively related to sperm quality, while NONRATG027523.1, NONRATG017183.2 and NONRATG023747.2 were positively related to sperm quality. The lncRNAs promote spermatogenic cell apoptosis and inhibit spermatogonia and spermatocyte proliferation and meiotic spermatocytes by regulating the PI3K–Akt signalling pathway. Conclusion DE lncRNAs may be potential biomarkers for predicting the risk of spermatogenic dysfunction in VC and the effect of surgical repair. These DE lncRNAs promote spermatogenic dysfunction by regulating the PI3K–Akt signalling pathway.

Abstract
This study aimed to confirm the expression of the seminal plasma long noncoding RNAs (lncRNAs) microRNA210 host gene (MIR210HG) in varicocele (VC) patients, to further explore the association between MIR210HG and VC severity and to evaluate whether MIR210HG can predict VC-related dyszoospermia. Semen samples from 188 VC patients and 92 healthy men were collected. Quantitative reverse transcriptase PCR detected seminal plasma MIR210HG levels. Receiver operating characteristic analysis assessed the ability of MIR210HG to screen patients with VC, or to screen VC patients with abnormal semen quality. Logistic analysis assessed the value of MIR210HG in predicting dyszoospermia in VC patients. The levels of MIR210HG in seminal plasma of VC patients were upregulated, which could screen VC patients. In addition, the levels of seminal plasma MIR210HG were upregulated with VC severity and were downregulated at 6 months after surgery in VC patients. Moreover, elevated MIR210HG levels in VC patients with abnormal semen quality could screen patients with abnormal semen quality and could independently predict the occurrence of dyszoospermia in VC patients. Seminal plasma MIR210HG expression is upregulated in VC patients, is associated with the severity of VC and may function as an independent predictor of VC-related dyszoospermia.

Abstract
The World Health Organization predicts that infertility will be the third major health threat after cancer and cardiovascular disease, and will become a hot topic in medical research. Studies have shown that epigenetic changes are an important component of gametogenesis and related reproductive diseases. Epigenetic regulation of noncoding RNA (ncRNA) is appropriate and is a research hotspot in the biomedical field; these include long noncoding RNA (lncRNA), microRNA (miRNA), and PIWI-interacting RNA (piRNA). As vital members of the intracellular gene regulatory network, they affect various life activities of cells. LncRNA functions as a molecular bait, molecular signal and molecular scaffold in the body through molecular guidance. miRNAs are critical regulators of gene expression; they mainly control the stability or translation of their target mRNA after transcription. piRNA functions mainly through silencing genomic transposable elements and the post-transcriptional regulation of mRNAs in animal germ cells. Current studies have shown that these ncRNAs also play significant roles in the reproductive system and are involved in the regulation of essential cellular events in spermatogenesis and follicular development. The abnormal expression of ncRNA is closely linked to testicular germ cell tumors, poly cystic ovary syndrome and other diseases. This paper briefly presents the research on the reproductive process and reproductive diseases involving ncRNAs.
