Lao X, Wang Y, Huang R, He Y, Lu H, Liang D. Genetic variants of LncRNAs HOTTIP and MEG3 influence nasopharyngeal carcinoma susceptibility and clinicopathologic characteristics in the Southern Chinese population. Infect Agent Cancer 2024; 19:32. [PMID: 39049088 PMCID: PMC11270775 DOI: 10.1186/s13027-024-00591-6] [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: 05/07/2024] [Accepted: 06/19/2024] [Indexed: 07/27/2024] Open
Abstract
OBJECTIVE Recent studies have indicated that HOTTIP and MEG3 are associated with the initiation and progression of various types of tumors, including nasopharyngeal carcinoma (NPC). This investigation aimed to elucidate the impact of HOTTIP and MEG3 polymorphisms on the susceptibility and clinicopathologic characteristics of NPC. METHODS This research employed next-generation sequencing and multiplex PCR to assess the polymorphisms of HOTTIP rs1859168 and MEG3 rs7158663 in 200 NPC and 200 healthy individuals respectively. HOTTIP and MEG3 expression were assessed via qRT-PCR assessment. Furthermore, the genotypes and alleles frequency of rs1859168 and rs7158663 were compared between healthy and NPC individuals to elucidate their influence on NPC susceptibility and relation with clinicopathologic characteristics. RESULTS In comparison with the healthy cohort, the presence of HOTTIP rs1859168 CC genotype and the C allele were markedly linked with increased NPC incidence (p < 0.05). Furthermore, the MEG3 rs7158663 AA genotype and the A allele also indicated an increased risk of NPC (p < 0.05). The subgroup analysis of age, EBV infection, gender, nationality, smoking, and drinking status revealed no marked association between rs1859168 and rs7158663 genotypes and these potential confounding factors. Moreover, it was observed that rs1859168 CC and rs7158663 AA genotypes were related to local tumor invasion and lymph node metastasis. Additionally, HOTTIP indicated a marked elevation, while MEG3 substantially reduced in NPC samples than the normal nasopharyngeal biospecimens. Patients who carried CC or CA genotypes rather than the HOTTIP rs1859168 AA genotype, had substantially higher HOTTIP levels, while patients with rs7158663 AA or GA genotypes indicated notably lower expression of MEG3 than GG genotype carriers. CONCLUSION Individuals with genetic variants of HOTTIP rs1859168 and MEG3 rs7158663 might have an increased risk of NPC susceptibility and related clinicopathologic characteristics, potentially by affecting the expression of HOTTIP and MEG3.

Abstract
BACKGROUND Long intergenic non-coding RNA, is one type of lncRNA, exerting various cellular activities, as does ncRNA, including the regulation of gene expression and chromatin remodeling. The abnormal expression of lincRNAs can induce or suppress carcinogenesis. MAIN BODY LincRNAs can regulate cancer progression through different mechanisms and are considered as potential drug targets. Genetic variations such as single nucleotide polymorphisms (SNPs) in lincRNAs may affect gene expression and messenger ribonucleic acid (mRNA) stability. SNPs in lincRNAs have been found to be associated with different types of cancer, as well. Specifically, LINC00511 has been known to promote the progression of multiple malignancies such as breast cancer, colorectal cancer, lung cancer, hepatocellular carcinoma, and others, making it a promising cancer prognostic molecular marker. CONCLUSION LincRNAs have been proved to be associated with different cancer types through various pathways. Herein, we performed a comprehensive literature and in silico databases search listing lncRNAs, lincRNAs including LINC00511, lncRNAs' SNPs, as well as LINC00511 SNPs in different cancer types, focusing on their role in various cancer types and mechanism(s) of action.

Serum lncRNAs, NBAT-1, and FOXCUT signature in hepatocellular carcinoma developed on top of chronic hepatitis C. Mol Carcinog 2023; 62:319-331. [PMID: 36440815 DOI: 10.1002/mc.23488] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 10/02/2022] [Accepted: 11/16/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Hepatocellular Carcinoma (HCC) is a universal health problem responsible for 8.2% of all cancer deaths. Numerous risk factors were documented to be contributed to HCC development with viral hepatitis C ranking as the major predisposing factor in Egypt. The presence of a detectable amount of long noncoding RNAs (lncRNAs) in the circulation is linked to the development and spread of tumors. LncRNAs NBAT-1 and FOXCUT expression levels were used as genetic markers for the detection of gastrointestinal tract cancers. We hypothesized that serum expression levels of NBAT-1 and FOXCUT are new biomarkers for HCC that are related to laboratory and pathological markers. PATIENTS AND METHODS This study included 165 hepatitis C virus (HCV)-related HCC Egyptian patients, 180 HCV-infected noncancer patients, and 180 healthy controls, the serum expression levels of NBAT-1 and FOXCUT were measured by using quantitative real-time polymerase chain reaction. RESULTS This study's results include that medians (inter-quartile range [IQRs]) of NBAT-1 in HCC and HCV patients were (1.9 [0.87-4.94], 10.01 [7.34-13.29] respectively) which exhibited significantly higher expression than controls, while the medians (IQRs) of FOXCUT in HCC and HCV patients were (0.15 [0.04-0.52], 6.42 [2.49-10.10], respectively) that exhibited significantly lower expression than controls regarding HCC patients but significantly higher expression than controls regarding HCV patients. In comparing serum fold changes of NBAT-1 and FOXCUT between HCC patients and HCV patients; we obtained significantly higher levels of target genes in HCV patients (p < 0.001) than in HCC patients. Also, a positive correlation was detected between NBAT-1 and FOXCUT in HCC group (r = 0.262, p = 0.001) and in HCV group (r = 0.937, p < 0.001). Higher serum NBAT-1 and FOXCUT were significantly associated with better clinical and laboratory data of the disease. Multivariate regression analysis showed that FOXCUT was an independent predictor for HCC among HCV patients (p < 0.001). CONCLUSION Our study cited that NBAT-1 and FOXCUT could be considered new diagnostic serum biomarkers for HCC on top of HCV.

Abstract
Colorectal cancer (CRC) is one of the most common cancers causing death worldwide. Many long noncoding RNAs (lncRNAs) have possible carcinogenic or tumor suppressor functions. Some lncRNA polymorphisms are useful for predicting cancer risk, and may help advance personalized therapy management. While the use of lncRNAs as biomarkers is promising, there are still drawbacks, and further studies are needed to verify the consistency of current outcomes in large-scale populations and different ethnicities. Single nucleotide polymorphisms (SNPs) can disrupt a lncRNAs' function, thus enhancing or hindering disease occurrence. SNPs can directly influence the lncRNA expression by interfering with transcription factor binding or affecting indirectly a regulatory factors' expression. Moreover, the association between lncRNAs and other RNAs or proteins may be disrupted by SNPs. This research sought to assess the association between lncRNA polymorphisms and CRC risk, as well as clinical and therapeutic consequences in certain cases.

The Influence of rs1859168 Polymorphism on Serum Expression of HOTTIP and Its Target miR-615-3p in Egyptian Patients with Breast Cancer. Biomolecules 2021; 11:733. [PMID: 34069089 PMCID: PMC8156858 DOI: 10.3390/biom11050733] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Revised: 05/02/2021] [Accepted: 05/07/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Polymorphisms of long noncoding RNAs are lately documented as hazardous factors for the development of numerous tumors. Furthermore, the evaluation of noncoding RNAs has emerged as a novel detector of breast cancer patients. We aimed to genotype the HOXA transcript at the distal tip (HOTTIP) rs1859168 and assess its relationship with the levels of the serum HOTTIP and its target miR-615-3p in patients with breast cancer (BC). METHODS One hundred and fifty-one patients with BC, 139 patients with fibroadenoma (FA), and 143 healthy participants were incorporated into the current study. The genotyping of rs1859168 and the measurements of the HOTTIP and miR-615-3p levels were assessed using quantitative real-time PCR. RESULTS We revealed a significant association between each of the CC genotypes, C allele, dominant and recessive models, and the increased risk of BC (p = 0.013, p < 0.001, p < 0.001, and p < 0.001, respectively) relative to the healthy controls. Similarly, the CC genotype, C allele, and recessive model were observed to be related to the increased incidence of BC with respect to FA (p < 0.001 for all). A significant upregulation of HOTTIP and a marked decrease of miR-615-3p were verified in patients with BC compared to each of the healthy individuals, patients with FA, and the non-BC group (healthy subjects + FA) (p < 0.001 for all). A significant negative correlation was demonstrated between the expression of HOTTIP and miR-615-3p in the serum of patients with BC. The HOTTIP expression was upregulated, while that of miR-615-3p was downregulated in patients with BC who carried the CC genotype with respect to those who carried the AA or AC genotypes (p < 0.05 for all). CONCLUSIONS The genetic variants of rs1859168 are linked to an increased susceptibility to BC. Moreover, HOTTIP and miR-615-3p may be used as novel indicators and targets for the treatment of patients with BC.
