Kulsange SE, Sharma M, Sonawane B, Jaiswal MR, Kulkarni MJ, Santhakumari B. SWATH-MS reveals that bisphenol A and its analogs regulate pathways leading to disruption in insulin signaling and fatty acid metabolism. Food Chem Toxicol 2024; 188:114667. [PMID: 38653447 DOI: 10.1016/j.fct.2024.114667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 03/24/2024] [Accepted: 04/14/2024] [Indexed: 04/25/2024]
Abstract
Bisphenol A (BPA) is an endocrine-disrupting chemical (EDC), associated with obesity and insulin resistance. The FDA prohibited the use of BPA-based polycarbonate resins in infant formula packaging; thus, its analogs, viz. Bisphenol S (BPS) and Bisphenol F (BPF) were considered alternatives in epoxy resins, plastics, and food cans. As these analogs might evoke a similar response, we investigated the role of Bisphenols (BPA, BPF, and BPS), on insulin signaling in CHO-HIRc-myc-GLUT4eGFP cells at environmentally relevant concentrations of 2 nM and 200 nM. Insulin signaling demonstrated that Bisphenols reduced phosphorylation of IR and AKT2, GLUT4 translocation, and glucose uptake. This was accompanied by increased oxidative stress. Furthermore, SWATH-MS-based proteomics of 3T3-L1 cells demonstrated that Bisphenol-treated cells regulate proteins in insulin resistance, adipogenesis, and fatty acid metabolism pathways differently. All three Bisphenols induced differentially expressed proteins enriched similar pathways, although their abundance differed for each Bisphenol. This might be due to their varying toxicity level, structural differences, and estrogen-mimetic activity. This study has important implications in addressing health concerns related to EDCs. Given that the analogs of BPA are considered alternatives to BPA, the findings of this study suggest they are equally potent in altering fatty acid metabolism and inducing insulin resistance.

Abstract
Bolanthus aziz-sancarii identified in 2019 for the first time is an endemic species of Bolanthus genus belonging to Caryophyllaceae family. Ten compounds were isolated from aerial parts of the plant. The potential antioxidant and anti-inflammatory effects of all four phases (hexane, chloroform, ethyl acetate, and water) from the methanol extract of the plant were investigated. After considering the findings regarding both antioxidant and anti-inflammatory capacities, it was decided to investigate the phytochemical profile of the EtOAc layer of B. aziz-sancarii. An abscisic acid-type sesquiterpene glucoside and nine flavonoid derivatives were isolated from the ethyl acetate fraction of the B. aziz-sancarii methanol extract through the use of column chromatography with silica gel.

Abstract
The increasing prevalence of obesity has prompted intensive research into understanding its role in pathogenesis and designing appropriate treatments. To determine the signals generated from the interaction of fat cells with a target organ, a reliable white adipocyte model in vitro is needed. Differentiated fibroblasts are the most extensively studied using in vitro cell models of white adipocytes. However, it can be argued that differentiated fibroblasts minimally recapitulate the consequences of obesity. Here, we describe 3T3-L1 MBX cells as a culture model for studying obese adipocytes and their effects. Differentiation of 3T3-L1 MBX cells was at first optimized and then maintained in the presence of fatty acids cocktail combination to induce the obese condition. Lipid accumulation and adipokine secretion profiles were analyzed. Results showed that fatty acid-maintained, differentiated 3T3-L1 MBX cells had significantly greater accumulation of lipids and significant changes in the adipokine secretions in comparison to differentiated 3T3-L1 MBX cells maintained in medium without fatty acids. To elucidate the molecular changes associated with adipogenesis and lipid accumulation profile of 3T3-L1 MBX cells, we have also explored the expression of some of the regulatory proteins related to the development and maintenance of adipocytes from the preadipocyte lineage.

Abstract
Cryogels are support materials which are good at mimicking extracellular matrix due to their excellent hydrophilicity, biocompatibility, and macroporous structure, thus they are useful in facilitating cell activities during healing process. In this study, polyvinyl alcohol-gelatin (PVA-Gel) based cryogel membranes loaded with pterostilbene (trans-3,5-dimethoxy-4-hydroxystilbene; PTS) (PVA-Gel/PTS) was synthesized as wound dressing materials. PVA-Gel and PVA-Gel/PTS were synthesized with the polymerization yields of 96% ± 0.23% and 98% ± 0.18%, respectively, and characterized by swelling tests, Brunauer-Emmett-Teller (BET) and scanning electron microscopy (SEM) analysis. The swelling ratios were calculated as 98.6% ± 4.93% and 102% ± 5.1%, macroporosities were determined as 85% ± 2.13% and 88% ± 2.2%, for PVA-Gel and PVA-Gel/PTS, respectively. It was determined that PVA-Gel and PVA-Gel/PTS have 17 m2 /g ± 0.76 m2 /g and 20 m2 /g ± 0.92 m2 /g surface areas, respectively. SEM studies were demonstrated that they have ~100 μm pore sizes. According to 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), trypan blue exclusion and live-dead assay results, it was observed that cell proliferation, cell number and cell viability were higher in PVA-Gel/PTS cryogel at 24, 48, and 72 h compared to PVA-Gel. A strong and transparent fluorescent light intensity was observed indicating higher cell population in PVA-Gel/PTS in comparison with PVA-Gel, according to 4',6-diamidino-2-phenylindole (DAPI) staining. SEM, F-Actin, Giemsa staining and inverted-phase microscope image of fibroblasts in PVA-Gel/PTS cryogels revealed that dense fibroblast proliferation and spindle-shaped morphology of cells were preserved. Moreover, DNA agarose gel data demonstrated that PVA-Gel/PTS cryogels had no effect on DNA integrity. Consequently, produced PVA-Gel/PTS cryogel can be used as wound dressing material to promote wound therapies, inducing cell viability and proliferation.

Antioxidants (Basel) 2022; 11:antiox11122398.

Abstract
Plants are an entity essential to the function of the biosphere as well as human health. In the context of human health, this research investigated the effect of Lasia spinosa (Lour) leaf methanolic extracts (LSML) on antioxidative enzymes and gene expression as well as biochemical and histological markers in a streptozotocin (STZ)-induced diabetes model. Fructose-fed streptozotocin (STZ)-induced diabetic animals were subjected to a four-week intervention followed by the assessment of the animal’s blood and tissues for enzymatic, biochemical, histological, and genetic changes. LSML-treated groups were shown to decrease plasma glucose levels and improve body and organ weights compared to the untreated group in a dose-dependent manner. At the doses of 125 and 250 mg/kg b.w., LSML were able to normalize serum, hepatic, and renal biochemical parameters and restore the pancreas, kidney, liver, and spleen tissue architectures to their native state. A considerable increase (p < 0.01) of liver antioxidant enzymes CAT, SOD, GSH, and a decrease of MDA level in LSML-treated groups were found at higher doses. The improved mRNA expression level of antioxidant genes CAT, SOD2, PON1, and PFK1 was also found at the doses of 125 mg/kg and 250 mg/kg BW when compared to untreated control groups. The results demonstrate that LSML impacts the upregulation of antioxidative gene expressions, thus improving the diabetic complications in animal models which need to be affirmed by compound-based antioxidative actions for therapeutic development.

Metabol Open 2022; 14:100189. [PMID: 35637658 PMCID: PMC9142648 DOI: 10.1016/j.metop.2022.100189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Revised: 05/01/2022] [Accepted: 05/14/2022] [Indexed: 11/26/2022] Open
Abstract
Background Diabetes, especially type-II, prevailed despite recent medical advances. An edible G. lotoides (GL) seed is sold in Ethiopian traditional market such as 'Merkato' and used in folkloric medicine to treat diabetes. But to date not scientifically proven in this optic. As a result, this study set out to validate this claim. Methods Following G. lotoides seed has been extracted, its antidiabetic efficacy was initially validated in vitro before in vivo investigation. The in vitro activity was probed by employing carbohydrate and lipid metabolizing enzymes inhibition assay. Based on this fact, the in vivo antidiabetic efficacy was conducted in normoglycemic, oral glucose-loaded and streptozotocin (150 mg/kg)-nicotinamide (65 mg/kg)-elicited type II diabetic rats. Results The extract's LD50 was found to be greater than 2 g/kg. In vitro tests pill up evidence that seed extract foils carbohydrate and lipid metabolizing enzyme activities (p < 0.001). On the other hand, seed extract significantly abridged blood glucose in normoglycaemic rats markedly (p < 0.05-0.001). The highest dose exhibited the strongest glucose tolerance effect, with a maximum slaying (41.1%) in glucose-loaded rats' plasma glucose (p < 0.001). All doses of the extract ameliorate blood glucose levels significantly in diabetic rats after 4 weeks of therapy (p < 0.05-0.001). Likewise, all test doses tempered harmful lipides in diabetic rats markedly (p < 0.05-0.001). But HDL (p < 0.01-0.001) and body weight losses (p < 0.05-0.001) were rectified. Conclusion In consequence, our data unveils the safety and glucolipotoxicity inhibition potential of G. lotoides seed extract, authenticating the traditional standpoint that it might be converted into a viable anti-diabetic lead upon subsequent investigations.
