Fibroblast growth factor 21 (FGF21) has emerged as a pleiotropic hormone and is known for its beneficiary roles in the management of diabetes and hyperglycaemia. However, the role of FGF21 during the transition from prediabetes to diabetes still remains unclear. Hence, the present study is aimed to understand the regulation of glucose homeostasis by FGF21 during the transition from prediabetes to diabetes in WNIN/GR-Ob rats. Nivolumab A total of 36 WNIN/GR-Ob obese male rats (28 days old) were divided into control and high sucrose (HS) groups and were fed ad libitum with their respective diets. These groups were sacrificed at different time points (week 1, 6, and 12) and various physical, biochemical, and molecular mediators were assessed to address FGF21 mediated glucose homeostasis. The study results revealed that rats developed impaired glucose tolerance and insulin resistance by exhibiting delayed glucose clearance from circulation, elevated fasting insulin, increased AUC glucose and HOMA-IR scores significantly; thereby rats demonstrated prediabetes by week 6 and diabetes complications by week 12. In line with the above, differential expression of genes attributed to FGF21 mediated glucose homeostasis, i.e., PPARα, FGF21, β-klotho, PPARγ, Adiponectin, Akt, and UCP1 suggest that the acute insulin sensitizing effect of FGF21 was significantly impaired during prediabetes to diabetes transition. In addition, increased gene and protein expression of FGF21 during the transition compared to controls could be a compensatory response to possibly counteract the metabolic stress imposed by high sucrose diet in WNIN/GR-Ob rats of the experimental group. Findings from the current study emphasize the potential role of FGF21 in glucose homeostasis and its attenuation might aggravate glucose impairment during the transition from prediabetes to diabetes in high sucrose diet induced WNIN/GR-Ob rats.Anti-Koch and HAART have been shown to independently induce toxicity to the liver and kidney, albeit available data are few and inconsistent. The present study evaluates the impact of Anti-Koch and HAART, when administered singly and in combination, on hepatic and renal status, and the possible role of adenine deaminase (ADA)/xanthine oxidase (XO) pathway. Anti-Koch and HAART administration were observed to independently impair hepatic and renal functions, diminish glutathione content, and substantially increase lipid peroxidation (MDA) and nitrogen reactive specie (NO). Coherently, these drugs caused significant accumulation of polymorphonuclear leucocytes, up-regulated ADA/XO signaling, increased uric acid production, and enhanced DNA fragmentation in the liver and kidney. Anti-Koch treatment did not significantly alter hepatic and renal levels of nitric oxide nor induce DNA fragmentation in the kidney. Co-administration of anti-Koch and HAART aggravated the observed biochemical alterations. Findings from the histopathological studies of the liver and renal tissues were in agreement with observed biochemical alterations. In conclusion, this report is the first to reveal that anti-Koch and HAART, when administered singly or in combination, attenuate glutathione content and elevate uric acid production in the liver and kidney via upregulation of ADA/XO signaling with resultant oxidative and nitrosative stress, and increased DNA fragmentation.Alismatis rhizoma (AR) is the dried rhizome of Alisma orientale (Sam.) Juz. (Alismataceae). This traditional Chinese formula is diuretic, hypoglycemic, and hypolipidemic. Alisol C 23-acetate (AC23A) from AR is anti-inflammatory and ameliorates certain metabolic diseases. However, the mechanism by which AC23A mitigates osteoporosis is unknown. The present study investigated the anti-osteoporotic effects of AC23A in vivo and in vitro. In an ovariectomized (OVX) rat model, AC23A ameliorated OVX-induced organ coefficients and trabecular bone loss. In OVX rats, AC23A treatment lowered serum TRAP5b, CTK, β-CTX, TNF-α, IL-6, and IL-1β, raised serum E2, and did not significantly change serum OCN or BALP. AC23A inhibited osteoclast formation in a rat co-culture system without affecting osteoblast activity. RANK (receptor activator of nuclear factor kappaB) signaling channels are vital osteoclastogenesis transcription elements. AC23A inhibited RANK ligand (RANKL)-induced TRAP, c-Fos, MMP9, NFATc1, and CTK expression and JNK phosphorylation. Therefore, AC23A is anti-osteoclastogenic in vitro and in vivo by inhibiting RANKL-induced osteoclast differentiation and function. Moreover, AC23A could help prevent or limit osteoclast-mediated bone diseases by inhibiting osteoclastogenesis.4-chloro eugenol (4CE), a semisynthetic analog of phytomolecule eugenol exhibited potent antiplasmodial activity with IC50 in the range of 1.5-5 μM against sensitive as well as drug resistant strain of P. falciparum. This analog also showed synergy with a clinically used antimalarial drug artesunate and was able to curtail the IC50 of artesunate up to 4-5 folds. Although, 4CE did not show any effect on heme polymerization, the most common drug target in the malaria parasite, it could increase the level of reactive oxygen species (ROS) and reactive nitrogen species (RNS) alone as well as in combination with artesunate. Further, 4CE induced oxidative stress was observed to affect the macromolecules in terms of DNA damage, protein carbonylation and lipid peroxidation. At the physiological level, cellular organelles like mitochondria and endoplasmic reticulum were observed to be get affected by 4CE in terms of membrane depolarization and calcium ion leakage respectively. These observations could be validated by expression analysis of oxidative stress responsive genes and proteins. Further, in in vivo assay, 4CE showed significant chemo-suppression of parasitemia as well as an increase in mean survival time in the murine malaria model. Interestingly, in combination with artesunate, 4CE showed higher chemo-suppression as well as enhanced mean survival time at a much lower concentrations of both the partners as compared to an individual dose of artesunate and 4CE. A combination of 4CE and artesunate was also observed to attenuate cerebral malaria pathogenesis.
