Placental angiogenesis, essential for sufficient blood flow and nutrient exchange between mother and fetus, may be affected by GDM. However, the role of angiogenic markers in GDM remains unclear. This study aims to investigate angiogenic markers from early pregnancy till delivery and their relationship with placental dimensions. This study is a part of a longitudinal study, where a total of 1154 women were recruited, out of which 167 women developed GDM (15.2%). The current study includes a total of 130 women randomly selected (65 GDM and 65 Non-GDM women). Plasma and placental levels of angiogenic markers such as VEGF, PLGF and sFlt-1/Flt-1 were estimated. Placental dimensions and birth outcomes were recorded, and associations between angiogenic markers and these parameters were examined. sFlt-1 (p < 0.05) levels were higher at V1 (11-14 weeks) in GDM women as compared to Non-GDM women. Placental PLGF (p < 0.01) and Flt-1 (p < 0.05) levels were lower in the GDM group. PLGF and Flt-1 were negatively associated with placental dimensions such as major axis, minor axis and breadth of the placenta. This study reveals altered expression of placental angiogenic markers in women with GDM, potentially affecting placental development and function. Negative correlations between these markers and placental dimensions suggest their influence on pregnancy outcomes in GDM.</p>","PeriodicalId":18724,"journal":{"name":"Molecular and Cellular Biochemistry","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142896167","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}

Cell experiments: The differential adhesion method was used to obtain Sprague Dawley (SD) suckling rat CFs and cardiomyocytes (CMs), while the ultracentrifugation method was used to obtain CM-EVs. Transmission electron microscopy and nanoparticle tracking technology were used to analyze and determine the morphology and particle size of CM-EVs. Western blotting was used to identify the expression of EV markers CD9, CD63, and Alix proteins. Small molecule combination of CHIR99021, Forskolin, Dorsomorphin, SB431542, and Valproic acid (CFDSV) and CFDSV + CM-EVs combination were used to induce CFs to differentiate into cardiomyocytes. The expression of cellular morphological changes, myocardial-specific protein cardiac troponin T (cTnT), and α-actinin were detected on the 3rd, 6th, 9th, and 15th day of reprogramming, respectively. After transfection and inhibition of miRNA-133, immunofluorescence, RT-qPCR, and Western blotting techniques were used to detect the expression of cTnT and α-actinin of induced CFs in the CMs group (CM-EVs), miRNA-133 high expression group (133H), and miRNA-133 inhibition group (133I). Animal experiment: CM-EVs were injected into the margin of myocardial infarction in rats. Cardiac function was detected by echocardiography before and 4 weeks after infarction, and the pathological changes were detected by HE and Masson staining, while Tunel and CD31 fluorescence staining were used to detect myocardial cell apoptosis and angiogenesis. CFs in the CM-EVs group expressed cTnT and α-actinin after induction, and the expression intensity gradually increased with the extension of induction time. On the 15th day after induction, cTnT-positive cells accounted for 85.6% of the total cell count, while the CFDSV group accounted for 48.8%. The majority of cells expressed GATA-binding protein 4 (GATA4), NK2 homeobox 5 (Nkx-2.5), and connexin 43 (Cx43). The RT-qPCR analysis showed the induced CFs expressed mature cardiomyocyte markers, including cTnT, Ryr2, Nkx-2.5, and GATA, which were similar to those of CMs (P &lt; 0.05). Upon induction of CFs into iCMs, iCMs expressed cardiac precursor cell markers, such as source domain transcription factor-1 (Isl-1), mesodermal posterior spiral transcription factor-1 (Mesp-1), GATA4, and fetal liver kinase-1 (Flk-1). RT-qPCR, Western blotting, and immunofluorescence results showed that cTnT and α-actinin were highly expressed in CFs induced by CM-EVs group and 133H group until the 15th day, while the expression levels were low in cont group and 133I group. In animal in vivo experiments, injection of CM-EVs was found to alleviate myocardial fibrosis and reduce apoptosis of myocardial cells in the infarcted area compared to the MI group (P &lt; 0.001).

Gut microbiota dysbiosis has been recently recognized as a key contributor to MetS, leading to advancements in gut microbiome-based interventions to improve health outcomes. Considering the unique challenges associated with the use of pre/probiotics, short-chain fatty acids (SCFA), also known as postbiotics, have emerged as promising therapeutic agents due to their role in modulating host metabolism and physiology. Considering this, the aim of the current study was to explore the therapeutic potential of SCFA (butyrate, propionate, and acetate) supplementation against a high-fat diet (HFD)-induced experimental model of MetS in male Wistar rats. Alterations in body weight, lipid profile, histopathology, and adipose tissue accumulation were assessed to establish SCFA-mediated amelioration of experimental MetS. Further, the enzymatic (GPx, Catalase, GR, and GST) and non-enzymatic (LPO, total ROS, and Redox ratio were evaluated. The results indicated that SCFA supplementation could effectively mitigate key features of MetS. A significant reduction in body weight gain and fasting blood glucose levels, along with markedly lowered triglycerides, total cholesterol, and LDL levels, with partial restoration of HDL levels was observed following SCFA supplementation. SCFA administration also attenuated MetS-associated hepatic damage as studied by histopathological investigation and analysis of liver function marker enzyme activities. Such ameliorative effects of SCFA against HFD-induced MetS were owed to potential redox modulation studied using enzymatic and non-enzymatic oxidative stress markers. In conclusion, the study's outcomes show that SCFA supplementation could potentially be used against managing MetS. It underscores the therapeutic potential of SCFA by placing them as a novel gut microbiome-based dietary approach to improve metabolic health and reduce the risk of MetS-associated complications. However, more detailed mechanistic explorations are warranted in the future, leading to their beneficial role in MetS contributing to holistic health outcomes.</p>","PeriodicalId":18724,"journal":{"name":"Molecular and Cellular Biochemistry","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142872601","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}

An increasing body of evidence links the combined exposure to multiple environmental toxicants with the occurrence and severity of metabolic diseases. Endocrine disruptors (EDs) are ubiquitous chemicals or mixtures with persistent deleterious effects on the living organisms beyond the endocrine system impairment; in particular, those known as metabolism-disrupting chemicals (MDCs), increase the risk of the metabolic pathologies in adult organism or its progeny. Being largely lipophilic, MDCs mainly target the adipose tissue and elicit mitochondrial dysfunction by interfering with mitochondrial bioenergetics, biogenesis, dynamics and/or other functions. Plastics, when broken down into micro- and nano-plastics (MNPs), have been detected in several human tissues, including the liver. The harmful interplay between inflammatory and redox processes, which mutually interact in a positive feed-back loop, hence the term oxidative inflammation (\"OxInflammation\"), occurs both at systemic and organ level. In both liver and adipose tissue, oxinflammation contributes to the progression of the metabolic dysfunction-associated steatotic liver disease (MASLD). Moreover, it has been reported that individuals with MASLD may be more susceptible to the harmful effects of toxicants (mainly, those related to mitochondria) and that chronic exposure to EDs/MDCs or MNPs may play a role in the development of the disease. While liver has been systematically investigated as major target organ for ambient chemicals, surprisingly, less information is available in the literature with respect to the adipose tissue. In this narrative review, we delve into the current literature on the most studied environmental toxicants (bisphenols, polychlorinated biphenyls, phthalates, tolylfluanid and tributyltin, per-fluoroalkyl and polyfluoroalkyl substances, heavy metals and MNPs), summarize their deleterious effects on adipose tissue, and address the role of dysregulated mitochondria and oxinflammation, particularly in the setting of MASLD.</p>","PeriodicalId":18724,"journal":{"name":"Molecular and Cellular Biochemistry","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142864799","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}
