Abstract
Gynostemma pentaphyllum (G. pentaphyllum) is a perennial liana herb of the Cucurbitaceae family which has both nutraceutical and pharmacological functions. The objective of the current study was to investigate the preventative effects of G. pentaphyllum and Gypenoside-IV (GP-IV, a saponin monomer in G. pentaphyllum) on metabolic symptoms in high fat diet induced obese (DIO) mice with gut microbiota dysbiosis. G. pentaphyllum water extract (GPWE, 150 mg/kg•d- 1) and GP-IV (50 mg/kg•d- 1) were orally administered to DIO mice by gavage for 10 weeks. The results showed that both GPWE and GP-IV prevented obesity development by decreasing body weight gain, reducing fat mass/body weight ratio and inhibiting adipocyte hypertrophy. GPWE and GP-IV also improved lipid profile and glucose tolerance effectively. Moreover, GPWE and GP-IV treatments partly restored gut microbiota in DIO mice. Typically, GPWE and GP-IV reduced Firmicutes to Bacteroidetes ratio, increased the abundance of certain health-promoting bacteria and reduced the abundance of microbiota that were associated with metabolic disorders. We conclude that GPWE and GP-IV can ameliorate metabolic symptoms possibly via modulating gut microbiota in DIO mice.

JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2021; 69:11900-11911.

Abstract
This study explored whether the antiobesity effect of theabrownin (TB) extracted from Fu brick tea (FBT) was associated with the activation of brown adipose tissue (BAT) or browning of the white adipose tissue (WAT) in mice fed a high-fat diet (HFD). Mice were divided into five groups, which received a normal diet, HFD, or HFD plus TB (200, 400, and 800 mg/kg), respectively. A 12-week administration of TB in a dose-dependent manner reduced the body weight and WAT weight and improved lipid and glucose disorders in the HFD-fed mice (p < 0.05). TB also promoted the expression of thermogenic and mitochondrial genes, whereas inflammation genes were reduced in interscapular BAT (iBAT), inguinal WAT (iWAT), and epididymis white adipose tissue (eWAT), accompanied by improvement in the intestinal homeostasis by improving SCFAs, especially butyric acid levels (p < 0.05), which was related to thermogenic and inflammatory factors of iBAT and iWAT. Mechanistically, TB was shown to efficiently promote thermogenesis by stimulating the AMPK-PGC1α pathway with an increase in uncoupling protein 1 (UCP1). Conclusively, these findings suggest that long-term consumption of TB can enhance BAT activity and WAT browning by activating the AMPK-PGC1α pathway and modulating SCFAs; meanwhile, SCFAs regulating TB improved inflammatory disorder in HFD-fed mice.

Abstract
Background Cyclophilin D (CypD) is a mitochondrial matrix protein involved in liver steatosis and fibrosis in vitro. However, the role of CypD in the development of fatty liver and liver fibrosis in humans has not been determined. Purpose To measure the serum level of CypD in patients with type 2 diabetes (T2DM) and nonalcoholic fatty liver disease (NAFLD) and to assess its relation to the presence of hepatic steatosis and fibrosis in this group of patients. Patients and Methods In this cross-sectional study, 30 patients with diabetes and NAFLD were compared to 30 patients with diabetes without NAFLD and 30 age- and sex-matched healthy subjects. Abdominal ultrasound was used to diagnose NAFLD. Serum CypD was measured using ELISA. Fibrosis-4 (FIB-4) index, AST to platelet ratio index (APRI), and NAFLD fibrosis score (NFS) were used as markers of liver fibrosis in patients with NAFLD. Patients with NAFLD were divided into two subgroups based on FIB-4 index: patients with liver fibrosis (FIB-4 >1.45) and patients without liver fibrosis (FIB-4 <1.45). CypD and other clinical and biochemical parameters were validated as predictors of NAFLD and liver fibrosis in diabetic patients in multivariate logistic regression analysis. Results Diabetic patients with NAFLD had higher serum CypD levels than those without NAFLD (11.65±2.96 vs 6.58±1.90 ng/mL, respectively, P <0.001). Correlation analysis revealed a significant positive correlation between CypD and FIB-4 index (P=0.001), APRI (P=0.013) and NFS (P<0.001). GGT and CypD were the only predictors of NAFLD. For the prediction of significant fibrosis, AUROC of CypD was 0.835 with a cutoff >14.05 ng/mL provides specificity of 81.8% and sensitivity of 75%. Conclusion Serum CypD is related to hepatic steatosis and fibrosis in diabetic patients. Serum CypD may thus provide a novel marker and therapeutic target of NAFLD and liver fibrosis.

Abstract
Leptin and insulin use overlapping signaling mechanisms to modify hepatic glucose metabolism, which is critical in maintaining normal glycemia. We examined the effect of an increase in central leptin and insulin on hepatic glucose metabolism and its influence on serum glucose levels. Chronic leptin infusion increased serum leptin and reduced hepatic SH-phosphotyrosine phosphatase 1, the association of suppressor of cytokine signaling 3 to the insulin receptor in liver and the rise in glycemia induced by central insulin. Leptin also decreased hepatic phosphoenolpyruvate carboxykinase levels and increased insulin's ability to phosphorylate insulin receptor substrate-1, Akt and glycogen synthase kinase on Ser9 and to stimulate glucose transporter 2 and glycogen levels. Peripheral leptin treatment reproduced some of these changes, but to a lesser extent. Our data indicate that leptin increases the hepatic response to a rise in insulin, suggesting that pharmacological manipulation of leptin targets may be of interest for controlling glycemia.

Abstract
PURPOSE To assess the effect of immune modulators, cyclosporin A and fingolimod, on high fat diet-induced obesity and insulin resistance. METHODS C57BL/6 mice were fed a high fat diet and injected intraperitoneally with cyclosporine A, fingolimod, or vehicle twice weekly for 15 weeks. Body weight and food intake were manually measured every other day. Glucose tolerance test, insulin sensitivity, and body composition were examined and compared between the control and the immune modulator treated animals. Tissue samples were collected at the end of the experiment and examined for serum biochemistry, histology, and mRNA levels of marker genes for inflammation, and glucose and lipid metabolism in white and brown adipose tissues and in the liver. RESULTS Cyclosporine A and fingolimod suppressed high fat diet-induced weight gain, reduced hepatic fat accumulation, and improved insulin sensitivity. The beneficial effects are associated with altered expression of F4/80, Cd68, Il-6, Tnf-α, and Mcp-1 genes, which are involved in macrophage-related chronic inflammation in adipose and hepatic tissues. CONCLUSION Immune modulation represents an important intervention for obesity and obesity-associated insulin resistance.

Drug- not carrier-dependent haematological and biochemical changes in a repeated dose study of cyclosporine encapsulated polyester nano- and micro-particles: size does not matter.

Abstract
Biodegradable nanoparticles are being considered more often as drug carriers to address pharmacokinetic/pharmacodynamic issues, yet nano-product safety has not been systematically proven. In this study, haematological, biochemical and histological parameters were examined on 28 day daily dosing of rats with nano- or micro-particle encapsulated cyclosporine (CsA) to confirm if any changes observed were drug or carrier dependent. CsA encapsulated poly(lactide-co-glycolide) [PLGA] nano- (nCsA) and micro-particles (mCsA) were prepared by emulsion techniques. CsA (15, 30, 45 mg/kg) were administered by oral gavage to Sprague Dawley (SD) rats over 28 days. Haematological and biochemical metrics were followed with tissue histology performed on sacrifice. Whether presented as nCsA or mCsA, 45 mg/kg dose caused significant loss of body weight and lowered food consumption compared to untreated control. Across the doses, both nCsA and mCsA produce significant decreases in lymphocyte numbers compared to controls, commensurate with the proprietary product, Neoral(®) 15. Dosing with nCsA showed higher serum drug levels than mCsA presumably owing to the smaller particle size facilitating absorption. The treatment had no noticeable effects on inflammatory/oxidative stress markers or antioxidant enzyme levels, except an increase in ceruloplasmin (CP) levels for high dose nCsA/mCsA group. Further, only subtle, sub-lethal changes were observed in histology of nCsA/mCsA treated rat organs. Blank (drug-free) particles did not induce changes in the parameters studied. Therefore, it is extremely important that the encapsulated drug in the nano-products is considered when safety of the overall product is assessed rather than relying on just the particle size. This study has addressed some concerns surrounding particulate drug delivery, demonstrating safe delivery of CsA whilst achieving augmented serum concentrations.

Abstract
Lung interstitial fibrosis is a chronic lung disease, and few effective therapies are available to halt or reverse the progression of the disease. In murine and human lung fibrosis, the expression of CD147 is increased. However, the role of CD147 in lung fibrosis has not been identified, and it remains to be determined whether lung fibrosis would be improved by decreasing the expression of CD147. A murine bleomycin-induced lung interstitial fibrosis model was used in the experiments, and HAb18 mAbs and CsA were administered during the induction of lung fibrosis. In our study, we found that the HAb18 mAbs markedly reduced the collagen score and down-regulated M1 macrophages and Th17 cells. In vitro, flow cytometry analysis showed that M1 macrophages induced higher Th17 differentiation than M2 macrophages. After treatment with HAb18 mAbs or after reducing the expression of CD147 by lentivirus interference in M1 macrophages, the level of Th17 cells were significantly inhibited. In conclusion, HAb18 mAbs or CsA treatment ameliorates lung interstitial fibrosis. CD147 promoted M1 macrophage and induced the differentiation of Th17 cells in lung interstitial fibrosis, perhaps by regulating some cytokines such as IL-6, IL-1β, IL-12 and IL-23. These results indicated that CD147 may play an important role in the development of lung interstitial fibrosis.

Abstract
OBJECTIVE Cyclosporine A (CsA) and sirolimus (SRL) are immunosuppressive agents (IA) associated with new onset diabetes after transplantation and dyslipidemia. We aim to evaluate the molecular effects of CsA (5mg/kg/day) and SRL (1mg/kg/day) treatment for 3 and 9weeks on lipid metabolism, in Wistar rats. MATERIALS/METHODS Lipolysis was evaluated in isolated adipocytes, while triglycerides (TG) and non-esterified fatty acid (NEFA) were measured in serum. Gene and protein expression involved in lipid metabolism was assessed in adipose tissue and liver. RESULTS CsA and SRL treatments of rats for 3 and 9weeks increased isoproterenol-stimulated lipolysis by 5-9 fold and 4-6 fold in isolated adipocytes, respectively. While CsA increased adipocyte weight and diameter, as well as NEFA and TG levels in circulation after 9weeks, SRL treatment caused ectopic deposition of TG in the liver after 3weeks. Moreover, ACC1 and FAS protein expression was increased after 3weeks (>100%, p<0.01), while HSL was increased after 9weeks of CsA treatment. On the other hand, SRL decreased the expression of lipogenic genes, including ACC1 (50%, p<0.05), lipin1 (25%, p<0.05), PPAR-γ (42%, p<0.05) and SCD1 (80%, p<0.001) in adipose tissue, after 3weeks of treatment. CONCLUSION The effects of both IAs on expression of lipolytic and lipogenic genes suggest that these agents influence lipid metabolism, thus contributing to the dyslipidemia observed during immunosuppressive therapy.
