Abstract
Previous studies have suggested that certain variants in immune-related genes may participate in the pathogenesis of multiple sclerosis (MS), including rs17824933 in the CD6 gene, rs1883832 in the CD40 gene, rs2300747 in the CD58 gene, rs763361 in the CD226 gene, rs16944 in the IL-1β gene, rs2243250 in the IL-4 gene, and rs12722489 and rs2104286 in the IL-2Rα gene. However, the results remained inconclusive and conflicting. In view of this, a comprehensive meta-analysis including all eligible studies was conducted to investigate the association between these 8 selected genetic variants and MS risk. Up to June 2023, 64 related studies were finally included in this meta-analysis. The odds ratios (ORs) and corresponding 95% confidence intervals (CIs) calculated by the random-effects model were used to evaluate the strength of association. Publication bias test, sensitivity analyses, and trial sequential analysis (TSA) were conducted to examine the reliability of statistical results. Our results indicated that rs17824933 in the CD6 gene, rs1883832 in the CD40 gene, rs2300747 in the CD58 gene, rs763361 in the CD226 gene, and rs12722489 and rs2104286 in the IL-2Rα gene may serve as the susceptible factors for MS pathogenesis, while rs16944 in the IL-1β gene and rs2243250 in the IL-4 gene may not be associated with MS risk. However, the present findings need to be confirmed and reinforced in future studies.

The rs6576457 G > A variant in the MKRN3 gene promoter significantly increases the risk of central precocious puberty and lung cancer in Hubei Chinese population. Hum Mol Genet 2024:ddae131. [PMID: 39239972 DOI: 10.1093/hmg/ddae131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 08/14/2024] [Accepted: 08/29/2024] [Indexed: 09/07/2024] Open
Abstract
Makorin RING finger protein 3 (MKRN3) is a key inhibitor of the hypothalamic-pituitary-gonadal (HPG) axis. The association between MKRN3 gene variants and central precocious puberty (CPP) has been repeatedly examined. In a recent study, MKRN3 has been assigned a role of tumor suppressor in lung carcinogenesis. Therefore, it is hypothesized that MKRN3 may be the link between CPP and lung cancer (LC), and certain MKRN3 gene variants may affect individuals' susceptibility to CPP and LC. The rs12441287, rs6576457 and rs2239669 in the MKRN3 gene were selected as the target variants. Sanger sequencing was applied to genotype them in two sets of case-control cohorts, namely 384 CPP girls and 422 healthy girls, 550 LC patients and 800 healthy controls. The results showed that rs6576457 but not rs12441287 or rs2239669 was significantly associated with the risk of CPP and LC. Their association with CPP risk was further confirmed in the following meta-analysis. Subsequent functional assays revealed that the rs6576457 genotypes were correlated with differentially expressed MKRN3, and the rs6576457 alleles affected the transcription repressor Oct-1 binding affinity to the MKRN3 promoter. Collectively, the MKRN3 gene rs6576457 may participate in the CPP pathology and LC tumorigenesis in the Hubei Chinese population. However, the present findings should be validated in additional investigations with larger samples from different ethnic populations.

Abstract
PURPOSE Central precocious puberty (CPP) results from early activation of the hypothalamic-pituitary-gonadal (HPG) axis. To elucidate the molecular genetic basis of CPP, we here investigated the effects of polymorphism rs5780218, rs12998 and rs10158616 in KISS1 gene on CPP susceptibility. METHODS The three KISS1 gene polymorphisms were genotyped by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and Sanger sequencing in 422 healthy Hubei Chinese girls and 384 Hubei Chinese girls with CPP. RESULTS Single-locus analysis demonstrated that rs5780218 and rs12998 were significantly associated with CPP susceptibility in Hubei Chinese girls. Haplotype analysis exhibited that the AGG carrying the risk allele A of rs5780218 and the -GG carrying the protective allele - of rs5780218 were associated with increased and decreased CPP susceptibility in Hubei Chinese girls, respectively. The following meta-analysis confirmed the contribution of rs5780218 and rs12998 on CPP susceptibility in Chinese girls. CONCLUSIONS rs5780218 and rs12998 in the KISS1 gene may participate in genetic susceptibility to CPP in Chinese girls, and the KISS1 gene rs5780218 may serve as a genetic biomarker of CPP. However, the present findings should be validated in future studies with larger sample sizes in other ethnic populations.

Abstract
PURPOSE Currently, several genetic variants in ERα gene (rs2234693 and rs9340799), ERβ gene (rs1256049 and rs4986938), KISS1 gene (rs4889, rs1132506 and rs5780218), LIN28B gene (rs314263, rs314276 and rs314280), and MKRN3 gene (rs2239669) have been repeatedly explored for their contribution to precocious puberty (PP) susceptibility. However, the results remain conflicting rather than conclusive. We here performed a meta-analysis to identify the real susceptibility genetic variants for PP. METHODS After screening by inclusion criteria, 20 related studies were finally included in this meta-analysis. The odds ratios and 95% confidence intervals were calculated to assess the strength of association. Sensitive analysis, publication bias, and trial sequential analysis (TSA) were performed to evaluate the stability and reliability of results. RESULTS Rs2234693, rs9340799, and rs1256049 were significantly associated with PP susceptibility (p < 0.0084). Stratified analysis according to ethnicity showed that rs2234693 and rs9340799 were significantly associated with PP susceptibility in Asian and Chinese populations. Stratified analysis according to PP subtype showed that rs2234693 and rs9340799 were significantly associated with idiopathic central PP susceptibility in Asian and Chinese populations (p < 0.0084). The results of publication bias, sensitivity analysis, and TSA provided solid evidence for the association between these three variants and PP susceptibility. CONCLUSIONS Rs2234693 and rs9340799 in ERα gene and rs1256049 in ERβ gene may serve as susceptive factors for PP development. The present finding should be confirmed in replication studies and reinforced in functional studies, which will ultimately improve the feasibility of the application of these three PP-susceptible loci in clinical practice.

Head and neck cancer stem cell maintenance relies on mTOR signaling, specifically involving the mechanistic target of rapamycin complexes 1 and 2 (mTORC1 and mTORC2). Arch Oral Biol 2024; 157:105840. [PMID: 37939517 DOI: 10.1016/j.archoralbio.2023.105840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 10/13/2023] [Accepted: 10/29/2023] [Indexed: 11/10/2023]
Abstract
OBJECTIVE Emerging evidence suggests that the modest response of head and neck squamous cell carcinoma (HNSCC) to treatment is associated with cancer stem cells (CSC). However, the signaling pathways that play a role in HNSCC CSC maintenance and therapy response are not well-understood. In this study, we investigate the response of CSCs to phosphatase and tensin homolog (PTEN) modulation and its potential dependency on the mammalian target of rapamycin (mTOR) signaling. DESIGN PTEN deficiency was stably induced using short hairpin RNA (shRNA). Downregulation of RPTOR/mTORC1 and RICTOR/mTORC2 was achieved using small interfering RNA (siRNA). CSCs were evaluated through tumorsphere formation and were classified into various subtypes: parasphere, merosphere, and holosphere. We investigated the effect of rapamycin on CSC properties in both control and PTEN-deficient HNSCC cells. RESULTS PTEN deficiency led to an accumulation of CSCs and enhanced a favorable response to rapamycin treatment. The viability of HNSCC CSCs was dependent on mTOR signaling. Deficiencies in both mTORC1 and mTORC2 reduced the number of CSCs. However, CSCs with PTEN deficiency had a greater reliance on mTORC1 signaling. Interestingly, when considering CSC subtypes, a deficiency in mTORC2 led to an increased number of paraspheres in both the control and PTEN-deficient groups. CONCLUSIONS Loss of PTEN signaling increased the HNSCC CSC population, which can be targeted by rapamycin. However, the mTORC2 deficiency can induce a problematic selection of paraspheres CSCs subtype.

Abstract
BACKGROUND Autophagy can inhibit the survival of intracellular microorganisms including Mycobacterium tuberculosis (Mtb), and the PI3K/AKT/mTOR pathway plays a crucial role. This study investigated the association between PI3K/AKT/mTOR pathway autophagy-related gene polymorphisms and pulmonary tuberculosis (PTB) susceptibility. METHODS KEGG pathway and gene ontology (GO) databases were searched for genes belonging to the PI3K/AKT/mTOR and autophagy pathways. Thirty SNPs in nine genes were identified and tested for their associations with tuberculosis in 130 patients with PTB and 271 controls. We constructed genetic risk scores (GRSs) and divided the participants into 3 subgroups based on their GRSs:0-5, 6-10, and 11-16. RESULTS This analysis revealed that the AKT1 (rs12432802), RPTOR (rs11654508, rs12602885, rs2090204, rs2589144, and rs2672897), and TSC2 (rs2074969) polymorphisms were significantly associated with PTB risk. A decreasing trend was observed (P trend 0.020), in which a lower GRS was associated with a higher risk of PTB ([6-10] vs. [0-5]: OR (95%CI) 0.590 (0.374-0.931); [11-16] vs. [0-5]: OR (95%CI) 0.381 (0.160-0.906)). CONCLUSIONS Polymorphisms in AKT1, RPTOR, and TSC2 may influence susceptibility to PTB.
