Thus the potential for phthalate exposure and harm to humans, animals, and the environment is high because its presence is alarming. Phthalates can be ingested, inhaled, absorbed topically, or via iatrogenic exposure in animals and humans. This article aimed to ascertain the modes of exposure, fate and detection techniques, and harmful effects of phthalates on humans, animals, and the environment. This review also shows that the intake of phthalate above the established daily limit from sources such as food, toys, and air causes serious harm, including impaired immune function, difficulties in pregnancy, loss of reproduction, and damage to the kidneys, lungs, heart, and brain in humans. Children and pregnant women are the most impacted groups and phthalates also negatively affect the environment and wildlife. A few methods to determine phthalate exposure, such as the LC and the HPLC-MS/MS methods, which employ human fluid or dust air as a biomarker, are also addressed here. Consequently, this comprehensive review aims to provide a detailed analysis of the existing evidence regarding explicit links between exposure to phthalates and subsequent health outcomes that may be directly related to this exposure.

However, the conventional approach utilizes fresh/frozen tissue samples, which are not routinely available for most clinical adrenal adenoma specimens. This coupled with the fact that CS is relatively rare reduces the accessibility to CPAs for research. In order to circumvent this issue, our group recently developed a sequencing strategy that allowed the use of formalin-fixed paraffin-embedded (FFPE) CPA samples for mutation analysis. Our streamlined approach includes the visualization and genomic DNA (gDNA) capture of the cortisol-producing regions in the tumor using immunohistochemistry (IHC)-guided techniques followed by targeted and/or whole-exome sequencing analysis. This approach has the advantage of using both prospective and retrospective CPA cohorts since FFPE pathologic specimens are routinely banked.

Despite significant advancements in clinical trials, the ability of cancer cells to metastasize and resist apoptosis remains a major challenge. To address these issues, novel therapeutic interventions with high specificity for these processes are essential. Alpha-lipoic acid (ALA), an organosulfur compound derived from octanoic acid, possesses a range of pharmacological properties. This study hypothesizes that ALA would inhibit metastasis and induce cell apoptosis in OS. To evaluate the potential of ALA, its effects on the migration, metastasis, and cell cycle of MG-63 OS cells were assessed, along with its ability to trigger apoptosis. To these aims, MG-63 cells were exposed to varying concentrations of ALA, and cell viability was measured using the alamarBlue assay. The impact of ALA on cell cycle progression, apoptosis, migration, and metastasis was analyzed through flow cytometry, scratch assay, and gelatin zymography. After validating the expression of MMP2, MMP9, VEGF, VEGFR, BAX, BCL-2, and P53 by the GEO database, the expression levels of these genes were examined through quantitative PCR (qPCR). Eventually, molecular docking was employed to simulate the interactions between ALA and matrix metalloproteinase (MMPs). The results demonstrated that ALA significantly inhibited cell migration, induced cell cycle arrest, and promoted apoptosis by upregulating P53 and BAX expression while downregulating BCL-2 levels. Furthermore, ALA was found to suppress the activity and expression of MMP2 and MMP9 and reduce the expression of angiogenesis markers. Notably, ALA interacted directly with the active site of MMP2 and MMP9. These findings suggest that ALA has the potential to be a promising agent with anti-cancer effects on MG-63 cells, warranting further preclinical investigations.</p>","PeriodicalId":51106,"journal":{"name":"Journal of Steroid Biochemistry and Molecular Biology","volume":" ","pages":"106664"},"PeriodicalIF":2.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142856577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the regional differences in lifestyle and nutritional status, the target populations were stratified into 5 strata based on their economic region and in Ulaanbaatar, with equal samples drawn from each stratum using a cluster-randomized sampling design. A representative sample of 30 clusters [villages] was randomly selected using Probability Proportional to Size [PPS] methodology in each of the 4 regions and in Ulaanbaatar for a total of 150 cluster units. The selection of survey participants differed for the three sampling regions. Household eligibility was based on having a child 0-59 months of age, living in the household which was randomly selected from each cluster for a total of 450 households in each region. Households with a child 0-59 months of age were selected from household lists available at the kheseg or bagh level. All men 15-49 years of age who resided in the selected households were also eligible to participate in the survey. Serum concentration of 25-hydroxyvitamin D [25(OH)D] were measured using an enzyme-linked fluorescence assay in 377 men aged 15-49 years.
