Samples were collected from 96 women with PCOS and 91 control women, aged 20 to 45 years for both groups. Levels of AMH, estrogen, progesterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), LH/FSH ratio, endometrial growth rate (WHR), and body mass index (BMI) were measured. The results showed significantly lower AMH levels in women with PCOS compared to healthy women at the probability level (P=0.05). The results also demonstrated a significant positive association between the prevalence of PCOS and AMH levels for estrogen, LH, and LH/FSH. It had an inverse relationship with AMH, progesterone, FSH, endometrial growth rate (WHR), and body mass index (BMI). Furthermore, the risk of AMH deficiency in women with PCOS increases with age, due to decreased fertility and egg production from the ovaries, especially after the age of 30, as well as weight gain. This suggests that age-related declines in AMH concentrations and weight gain are indicative of increased risk factors for PCOS. Finally, this study demonstrated a relationship between PCOS risk factors and AMH concentrations, suggesting that low AMH concentrations increase the risk of PCOS, especially with age. This suggests the potential for incorporating AMH into early detection tests and the development of more effective treatments for this condition.","PeriodicalId":9802,"journal":{"name":"Cellular and molecular biology","volume":"71 6","pages":"30-34"},"PeriodicalIF":1.5,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144567190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, mechanisms through which introns regulate gene expression and function remain unclear. In this study, we successfully designed a protocol to assess the function of LPL intron 3 in LPL regulation. This was accomplished by constructing luciferase reporter vectors, containing full and partial intron 3 fragments from a healthy human DNA sample. These recombinant constructs facilitated the analysis of transcriptional activity using dual-luciferase reporter assays in cell lines. The results showed that the luciferase activity of the chimeric firefly luciferase reporter construct containing the full-length LPL intron 3 was higher than that of other constructs. In this study, a successful protocol was developed to assess the function of LPL intron 3 in regulation of the LPL gene.

Immune subtype classification was conducted with the ImmuneSubtypeClassifier (v0.1.0) R package. A nomogram was generated using the rms (v6.7-1) package. A risk score model based on 13 super-enhancer-related genes (SERGs) was constructed, demonstrating that patients in the low-risk group had significantly better prognosis. The SERGs signature significantly correlated with age, molecular and immune subtypes, IDH mutation, MTMG promoter methylation, 1p19q co-deletion, and expression of immune checkpoint genes in glioma patients.

Its genetic component exhibits significant ethnic variation and is closely associated with the personal evolution of the disease. However, although multiple loci have been identified, no functional variants have been identified. In this work, we selected some genes from the inflammatory response pathway and searched for SNV (single nucleotide variants) in their promoter region that could be associated with the disease. We compared cases of problematic alcohol consumption (n=66) with controls (n=73) in a population sample taken at the National University of Colombia, Bogotá headquarters. Peripheral blood DNA extraction was performed. We used PCR and Sanger sequencing to find 28 SNVs and one STR in 10 inflammatory response genes that are connected to alcoholism. Then, using various bioinformatic tools, the analysis of haplotypes, linkage disequilibrium, epistasis and genetic networks was carried out. Allele and genotypic frequencies for this Colombian population were reported for the first time. Additionally, we found haplotypes that could be protective and risk factors for the disease, and gene interactions that have cumulative effects related to the drinker phenotype. The investigation of haplotypes, gene interaction, and gene networks is a highly effective methodology for identifying potential associations in small samples.

Cullenia exarillata leaf samples were subjected to various DNA and RNA extraction techniques, and the resulting data were compared and analysed. The isolation of high-quality DNA and RNA is crucial for the advancement of molecular and biotechnological techniques that aim to preserve the endemic status of C. exarillata and this research is to establish an efficient procedure for extracting DNA and RNA from C. exarillata. This method will make molecular and genomic research easier in forestry and conservation fields. In this research, we evaluated various methods for extracting high quality DNA and total RNA from C. exarillata tree, incorporating minor modifications in standard procedure. To acquire DNA and RNA of superior quality, a comparison was made between conventional DNA and RNA extraction methods and a variety of commercial kits thatrevealed the conventional technique yielded DNA samples of superior purity and concentration. It was discovered that combining modified commercial and conventional procedures yielded RNA with exceptionally high concentration and purity. The Agilent 2100 Bioanalyzer and NanoDrop spectrophotometer ensure the impeccable purity of the nucleic acids generated via these procedures. Additionally, the application of agarose gel electrophoresis unveiled unique bands. Further investigation was conducted to validate the purity and amplification of the DNA and RNA that were collected.
