Synthesis of series [17(20)Z]- and [17(20)E]-pregna-5,17(20)-dien-21-oyl amides, containing polar substituents in amide moiety, based on rearrangement of 17α-bromo-21-iodo-3β-acetoxypregn-5-en-20-one caused by amines, is presented. The titled compounds were evaluated for their potency to regulate sterol and triglyceride biosynthesis in human hepatoma Hep G2 cells in comparison with 25-hydroxycholesterol. Three [17(20)E]-pregna-5,17(20)-dien-21-oyl amides at a concentrations of 5 μM inhibited sterol biosynthesis and stimulated triglyceride biosynthesis; their regulatory potency was dependent on the structure of amide moiety; the isomeric [17(20)Z]-pregna-5,17(20)-dien-21-oyl amides were inactive.

Nesfatin-1 as a crucial mediator of glucose homeostasis in the reptile, Hemidactylus flaviviridis.

Nesfatin-1 is a crucial regulator of energy homeostasis in mammals and fishes, however, its metabolic role remains completely unexplored in amphibians, reptiles, and birds. Therefore, present study elucidates role of nesfatin-1 in glucose homeostasis in wall lizard wherein fasting stimulated hepatic nucb2/nesfatin-1, glycogen phosphorylase (glyp), phosphoenolpyruvate carboxykinase (pepck), and fructose 1,6-bisphosphatase (fbp), while feeding upregulated pancreatic nucb2/nesfatin-1 and insulin, suggesting towards tissue-specific dual role of nesfatin-1 in glucoregulation. The glycogenolytic/gluconeogenic role of nesfatin-1 was further confirmed by an increase in media glucose levels along with heightened hepatic pepck and fbp expression and concomitant decline in liver glycogen content in nesfatin-1-treated liver of wall lizard.

Background: Major depression is classified into distinct subtypes: simple (SDMD) and major dysmood disorder (MDMD). MDMD patients exhibit elevated atherogenicity and decreased reverse cholesterol transport (RCT). However, comprehensive data regarding lipid metabolism is absent in first episode (FE)-SDMD.

Objective: Gestational diabetes mellitus (GDM) is a common complication during pregnancy and increases the risk of metabolic diseases in offspring. We hypothesize that the poor intrauterine environment in pregnant women with GDM may lead to chromosomal DNA damage and telomere damage in umbilical cord blood cells, providing evidence of an association between intrauterine programming and increased long-term metabolic disease risk in offspring.
Methods: We measured telomere length (TL), serum telomerase (TE) activity, and oxidative stress markers in umbilical cord blood mononuclear cells (CBMCs) from pregnant women with GDM (N=200) and healthy controls (Ctrls) (N=200) and analysed the associations of TL with demographic characteristics, biochemical indicators, and blood glucose levels.
Untargeted metabolomics analysis of glycerophospholipid metabolism in very low birth weight infants administered multiple oil lipid emulsions.

Department of Intensive Care Unit, Hangzhou Women's Hospital, Hangzhou, 310016, Zhejiang, China.
Background: To compare the impact of two different lipid emulsions, specifically a soybean oil-based emulsion and a multiple oil emulsion (soybean oil, medium-chain triglycerides, olive oil, and fish oil, SMOF), on serum metabolites of very low birth weight (VLBW) infants using untargeted metabolomics analysis.
Methods: A comparative study was conducted on 25 VLBW infants hospitalized in neonatal intensive care units (NICU) of Hangzhou Women's Hospital in 2023. The infants were divided into the SMOF group (13 cases) and the soybean oil group (12 cases) based on the type of lipid emulsion used during parenteral nutrition.

Background: Fibroblast Growth Factor 21 (FGF21) is a naturally occurring peptide hormone involved in the regulation of glycolipid metabolism, and it shows promise as a potential treatment for type 2 diabetes mellitus (T2DM). However, the short half-life and poor pharmacokinetics of native FGF21 limit its efficacy in reducing hyperglycemia in vivo. Therefore, maintaining stable and sustained blood concentrations of FGF21 is crucial for its role as an effective regulator of glycolipid metabolism in vivo.
