Emerging links between FOXOs and diabetic complications.

Diabetes and its complications are increasing worldwide in the working population as well as in elders. Prolonged hyperglycemia results in damage to blood vessels of various tissues followed by organ damage. Hyperglycemia-induced damage in small blood vessels as in nephrons, retina, and neurons results in diabetic microvascular complications which involve nephropathy, retinopathy, and diabetic neuropathy.

Biological activities of meroterpenoids isolated from different sources.

Meroterpenoids are natural products synthesized by unicellular organisms such as bacteria and multicellular organisms such as fungi, plants, and animals, including those of marine origin. Structurally, these compounds exhibit a wide diversity depending upon the origin and the biosynthetic pathway they emerge from. This diversity in structural features imparts a wide spectrum of biological activity to meroterpenoids.

Gut-Brain Axis and Neurological Disorders-How Microbiomes Affect our Mental Health.

The gut microbiota is an essential part of the gastrointestinal tract and recent research, including clinical and preclinical studies, shed light on the interaction between the gut and the brain. A rising amount of evidence strongly proves the involvement of gut microbes in brain function and their contribution in altering behavior, mood, and ultimately in the pathogenesis of certain neurological conditions. The gut microbiota produces and modulates neurotransmitters such as GABA, serotonin, dopamine, glutamate, etc.

Autophagy-nutrient sensing pathways in diabetic complications.

The incidence of diabetes has been increasing in recent decades which is affecting the population of both, developed and developing countries. Diabetes is associated with micro and macrovascular complications which predominantly result from hyperglycemia and disrupted metabolic pathways. Persistent hyperglycemia leads to increased reactive oxygen species (ROS) generation, formation of misfolded and abnormal proteins, and disruption of normal cellular functioning.

Biochanin A Attenuates Cardiomyopathy in Type 2 Diabetic Rats by Increasing SIRT1 Expression and Reducing Oxidative Stress.

Diabetic cardiomyopathy is one of the major complications in type 2 diabetes associated with myocardial structure abnormality and major cause of morbidity in type 2 diabetic patients. Biochanin A is a methylated isoflavone present in flowering tops of Trifolium pratense reported for anti-inflammatory, anti-oxidant, anti-infective, anti-cancer and anti-diabetic activity. The study was designed to assess the efficacy of Biochanin A in type 2 diabetic cardiomyopathy.

SIRT1-FOXOs activity regulates diabetic complications.

The prevalence of diabetes is continuously increasing in the recent decades. Persistent hyperglycemia, hyperinsulinemia and the subsequent oxidative stress result in diabetic complications, primarily categorized as microvascular (nephropathy, retinopathy and neuropathy) and macrovascular (cardiomyopathy) complications. The complications are prevalent in both type 1 and type 2 diabetic patients.

Role of dietary modifications in the management of type 2 diabetic complications.

Diabetes is a chronic metabolic disorder with a high rate of morbidity and mortality. Insufficient insulin secretion and insulin action are two major causes for the development of diabetes, which is characterized by a persistent increase in blood glucose level. Diet and sedentary life style play pivotal role in development of vascular complications in type 2 diabetes.

Formononetin Ameliorates Diabetic Neuropathy by Increasing Expression of SIRT1 and NGF.

Diabetic neuropathy is commonly observed complication in more than 50 % of type 2 diabetic patients. Histone deacetylases including SIRT1 have significant role to protect neuron from hyperglycemia induced damage. Formononetin (FMNT) is known for its effect to control hyperglycemia and also activate SIRT1.

Trifolium pratense (Red Clover) Improve SIRT1 Expression and Glycogen Content in High Fat Diet-Streptozotocin Induced Type 2 Diabetes in Rats.

Flowering tops of Trifolium pratense L. (Fabaceae) are known for its traditional medicinal values. In present study, our aim was to investigate effect of standardized aqueous extract of flowering tops of Trifolium pratense L.

ER stress response mediates diabetic microvascular complications.

Endoplasmic reticulum (ER) homeostasis orchestrates the folding, modification, and trafficking of secretory and membrane proteins to the Golgi compartment, thus governing cellular functions. Alterations in ER homeostasis result in the activation of signaling pathways, such as the unfolded protein response (UPR), to regain ER homeostasis. Nevertheless, failure of UPR leads to activation of autophagy-mediated cell death.

Formononetin attenuates kidney damage in type 2 diabetic rats.

Aim: Diabetic nephropathy is the commonly developed complication of vasculature in type 2 diabetic patients. Chronic hyperglycemia leads to nephropathy in diabetics because of the formation of excessive reactive oxygen species and advanced glycation end products which is reflected in the form of glomerulosclerosis, tubular atrophy and interstitial fibrosis. As per the various reports reduction in SIRT1 expression in kidney tissue is key factor in the development of nephropathy in diabetes because its reduction in tissue is linked with excessive formation of ROS.

Reactivation of p53 gene by MDM2 inhibitors: A novel therapy for cancer treatment.

Cancer is an uncontrolled and abnormal growth of cells in the body. Gene that guards the cell cycle and function as tumor suppressor is p53 (also called as the guardian of the genome) which is encoded by the TP53 gene. Various events like DNA damage, heat shock, hypoxia and oncogene over expression, results in activation of p53.

Biochanin A improves insulin sensitivity and controls hyperglycemia in type 2 diabetes.

Biochanin A (5,7-Dihydroxy-4'-methoxyisoflavone) is an O-methylated isoflavone known for its anti-inflammatory, lipid lowering and anti-cancer activity. The current study was designed to find out antidiabetic efficacy of Biochanin A in type 2 diabetes in rats. Induction of type 2 diabetes mellitus in experimental animals was carried out by manipulation of diet using high fat diet for fourteen days and then administration of streptozotocin at low dose of 35 mg/kg, i.

Formononetin Treatment in Type 2 Diabetic Rats Reduces Insulin Resistance and Hyperglycemia.

Type 2 diabetic mellitus is a multifactorial metabolic disorder affecting huge population around the world. This indicates that there is an urgent unmet need of cost effective, new treatment strategies for type 2 diabetes mellitus with no or less side effects. Phenolic compounds including isoflavones are known for their beneficial effect in metabolic disorders.

Traditional uses, phytochemistry and pharmacology of the medicinal species of the genus Cordia (Boraginaceae).

Objectives: Cordia (family Boraginaceae) is a genus of deciduous flowering trees or shrubs comprising more than 300 species distributed widely in the tropical regions. The aim of this review was to provide exhaustive scientific information on traditional uses, phytochemistry and pharmacological activities of the 36 important species with medicinal value from the genus Cordia, to divulge prospects for further research on its therapeutic potential.

Key Findings: Leaves, fruit, bark and seed of a majority of the species were found to possess abundant ethnomedicinal value, but leaves were found to be used most frequently to treat many ailments such as respiratory disorders, stomach pain, wound, inflammation, myalgia, cough, dysentery and diarrhoea.
