Affecting 6-10% of women in childbearing age, PCOS is a leading cause of infertility worldwide. In recent years, there has been a growing acknowledgment of the involvement of adenosine monophosphate-activated protein kinase (AMPK) in the development of polycystic ovary syndrome (PCOS). The expression of AMPK is diminished in polycystic ovaries, and when AMPK is silenced in human granulosa cells, there is a rise in the expression of steroidogenic enzymes, resulting in increased production of estradiol and progesterone. Additionally, in mouse models, the inhibiting AMPK intensifies the polycystic appearance of ovaries and impairs the process of ovulation. Moreover, it has been shown that AMPK activators like metformin and resveratrol ameliorate PCOS associated signs and symptoms in experimental and clinical studies. These findings, collectively, indicate the key role of AMPK in the pathogenesis of PCOS. Understanding the role of AMPK in PCOS will offer rewarding information on details of PCOS pathogenesis and will provide novel more specific therapeutic approaches.

Around 40-60% of affected neonates die by two years of age or have severe disabilities and neurodevelopmental delays. The early assessments of brain injury using traditional clinical and biochemical indicators do not always align with its severity and recovery. This delays identifying neonates who may benefit from adjuvant therapeutic strategies and monitoring therapy response. Our aim was to identify specific proteins using proteomic approach to predict the severity of neonatal asphyxia so that its outcome can also be prevented. To achieve this goal a case-control study was conducted on 38 neonates, and serum and urine samples were collected within 24 h of life. Clinical findings, biochemical parameters, and outcomes of the neonates were recorded. A tandem mass spectrometry-based quantitative proteomics approach was used to identify proteins in the serum and urine of HIE neonates. Bioinformatics analyses were performed to assess the potential features and competence of the identified differentially expressed proteins. This resulted in identification of 51 differentially expressed proteins which were found common to both serum and urine proteomic data. Some of the promising biomarkers found were APOD, ORM1, SOD1, and FABP1. These proteins were associated with the pathways like Amyloid fiber formation, diseases of programmed cell death, detoxification of reactive oxygen species, and neurodegenerative diseases. This study will pave the way for identifying the biomarkers (proteins) that can screen neonates for brain injury and monitor the disease progression, which may reduce mortality and neurodevelopmental impairment.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s12291-023-01143-2.</p>","PeriodicalId":13280,"journal":{"name":"Indian Journal of Clinical Biochemistry","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11436606/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88485439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
