The aim of this research was to explore the underlying function of NRAV in GC. Through comprehensive bioinformatics analysis, a significantly elevation of NRAV was found in both human GC tissues and cell lines, which indicated the poor prognosis of GC patients. Then, we conducted a series of functional experiments to illustrate the role of NRAV in GC. The results showed that the down-regulation of NRAV exhibited a significant inhibitory effect on GC cell proliferation and migration, while NRAV overexpression promoted GC cell proliferation and migration. Through xenograft mouse tumor model, the suppression of NRAV led to a reduction in the growth of tumor mice, whereas overexpression of NRAV notably enhanced tumor growth. Finally, EFHC1 was revealed as the potential target gene of NRAV. Overall, our findings indicated the promising application of NRAV as a therapeutic target and prognostic biomarker for GC.","PeriodicalId":12499,"journal":{"name":"Gene","volume":" ","pages":"149134"},"PeriodicalIF":2.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142767903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, several genome-wide association studies (GWAS) have identified variants linked to asthma susceptibility. The DAD1 gene is known for regulating programmed cell death, and OXA1L is described for its involvement in mitochondrial biogenesis and oxidative phosphorylation. The present study aimed to identify variants in the DAD1 and OXA1L genes and to evaluate the association with asthma and atopy markers in adults. 1,084 individuals were divided into mild to moderate asthma, severe asthma, and participants with no asthma (controls). Association analyses were performed using a multivariate logistic regression model adjusted for sex, age, body mass index (BMI), smoking, forced expiratory volume in 1 s (FEV1), and component ancestry master (PC1) using PLINK 1.9 software. This study identified new variants in the DAD1 and OXA1L genes that had never been described before. The C allele of rs200470407 in OXA1L was negatively associated with poor asthma control (OR: 0.32; p-value 0.049) and increased IL-13 (p-value < 0.0001). The alternative allele of rs1681577 was associated with severe asthma (OR: 2.23; p-value 0.01), pulmonary obstruction (OR: 4.12; p-value 0.046), and eosinophilia (OR: 2.42; p-value < 0.001). Our findings demonstrate that variants in the DAD1 and OXA1L genes are linked to asthma and atopy in Brazilian adults.","PeriodicalId":12499,"journal":{"name":"Gene","volume":" ","pages":"149124"},"PeriodicalIF":2.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142767946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Melatonin (MT) plays an important role in plant responses to biotic and abiotic stresses, yet there is a lack of research on the specific role of limiting enzyme genes for MT biosynthesis in fast-growing woody plants. In this study, we investigated the function of PtoASMT, a key rate-limiting enzyme encoding gene for MT biosynthesis, which can be induced by drought, salt, and the phytohormones ABA, SA and JA. Our results show that: (1) PtoASMT was widely expressed in all tissues of poplar, but was highly expressed in petioles, moderately expressed in roots, stems, shoots and young leaves, exhibiting a typical diurnal expression rhythm in leaves, with the encoded protein localized on chloroplasts; (2) the content of MT was significantly promoted in overexpressing PtoASMT transgenic poplar plants, but there were no obvious differences in their growth and development; (3) overexpressing PtoASMT plants exhibited stronger drought tolerance, accumulating less reactive oxygen species (ROS) under drought stress relative to wild-type plants, whereas knockout PtoASMT plants were more sensitive and accumulated more ROS; (4) overexpressing PtoASMT plants were more resistant to fungi Dothiorella gregaria than WT plants, while knockout plants showed higher sensitivity; meanwhile, the expression of disease resistance-related genes (PRs and JAZ10) was significantly altered. We conclude that PtoASMT enhances the resistance of poplar to drought and Dothiorella gregaria by mediating MT biosynthesis in poplar. These findings contribute to a better understanding the role of ASMT gene in MT accumulation and stress resistance in poplar.","PeriodicalId":12499,"journal":{"name":"Gene","volume":" ","pages":"149154"},"PeriodicalIF":2.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has a high rate of progression and a poor prognosis, and effective biomarkers still need to be identified. The solute carrier family 12 (SLC12) family has been reported to be involved in various physiological and pathological processes, but their functional roles in glioma remain unclear.Methods: Using public datasets, we studied the mutation and expression level of SLC12 family genes in glioma and identified the significantly differentially expressed member solute carrier family 12 member 9 (SLC12A9). We further predicted the prognostic role of SLC12A9 in glioma by using the Kaplan-Meier method and Cox regression analysis. Then, we performed biological functional enrichment analysis. We focused on the relationships between SLC12A9 expression and immune infiltration in glioma. Meanwhile, we conducted in vitro experiments to evaluate the effect of SLC12A9 expression on glioma cells.Results: Among the members of the SLC12 family, SLC12A9 had the highest mutation rate in glioma, with gene amplification as the major mutation type, and its expression was significantly upregulated in glioma. Higher SLC12A9 expression was significantly associated with older age, higher grade, wild-type isocitrate dehydrogenase (IDH), and a worse prognosis. The functional enrichment analysis indicated that SLC12A9 is mainly related to ion channel annotation. Gene set enrichment analysis (GSEA) revealed that SLC12A9 was mainly related to the DNA replication pathway. Furthermore, we found that SLC12A9 correlated with tumor-infiltrating immune cells and immune checkpoints. Thus, SLC12A9 may be involved in regulating the immune response of glioma. Finally, our in vitro experiments revealed that silencing SLC12A9 dramatically inhibited glioma cell growth and migration.Conclusions: We showed that SLC12A9 may be a new predictive biomarker for glioma diagnosis, prognosis, and immunotherapy response, offering helpful guidelines to advance glioma treatment.","PeriodicalId":12499,"journal":{"name":"Gene","volume":" ","pages":"149136"},"PeriodicalIF":2.6,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142767909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study involved analyzing the role of PKM in 33 various types of cancers, along with investigating gene expressions, survival rates, clinical importance, genetic changes, immune system presence, and related signaling pathways. Furthermore, we evaluated the effects of PKM knockdown on human colon carcinoma, and glioblastoma cell lines by in vitro experimentation.Results: In most tumors, PKM expression was markedly increased and was associated with unfavorable overall survival (OS) in certain individuals. In addition, infiltration of macrophages was associated with PKM expression in various tumors. PKM was linked to glycolysis/gluconeogenesis, HIF-1 signaling, carbon metabolism, and NADPH regeneration in a mechanistic manner. Additionally, cell experiments showed that the knockdown of PKM could reduce the proliferation and migration abilities while promoting the apoptosis of Caco-2, and U-87 MG cells.Conclusion: PKM controls immune cell infiltration, impacts patient outcomes in various types of cancer, and plays an essential role in proliferation and migration in some tumor cells by affecting glycometabolism.
