Functional implications and therapeutic targeting of androgen response elements in prostate cancer.

The androgen receptor (AR) plays an essential role in the growth and progression of prostate cancer (CaP). Ligand-activated AR inside the nucleus binds to the androgen response element (ARE) of the target genes in dimeric form and recruits transcriptional machinery to facilitate gene transcription. Pharmacological compounds that inhibit the AR action either bind to the ligand binding domain (LBD) or interfere with the interactions of AR with other co-regulatory proteins, slowing the progression of the disease.

Insights on the role of anti-inflammatory and immunosuppressive agents in the amelioration of diabetes.

Diabetes is a major health problem worldwide. It is a chronic metabolic disorder that produces overt hyperglycemic condition that occurs either when the pancreas does not produce enough insulin due to excessive destruction of pancreatic β-cells (type 1 diabetes) or due to development of insulin resistance (type 2 diabetes). An autoimmune condition known as type 1 diabetes (T1D) results in the targeted immune death of β-cells that produce insulin.

Out-of-Hospital Cardiac Arrest during the COVID-19 Pandemic: A Systematic Review.

: Out-of-hospital cardiac arrest (OHCA) is a prominent cause of death worldwide. As indicated by the high proportion of COVID-19 suspicion or diagnosis among patients who had OHCA, this issue could have resulted in multiple fatalities from coronavirus disease 2019 (COVID-19) occurring at home and being counted as OHCA. : We used the MeSH term "heart arrest" as well as non-MeSH terms "out-of-hospital cardiac arrest, sudden cardiac death, OHCA, cardiac arrest, coronavirus pandemic, COVID-19, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Amelioration of diet-induced metabolic syndrome and fatty liver with sitagliptin via regulation of adipose tissue inflammation and hepatic Adiponectin/AMPK levels in mice.

Chronic consumption of unhealthy diet and sedentary lifestyle induces fatty liver and metabolic complications. Adipocytes get overloaded with lipid succeeding low-grade inflammation and disrupting adipokine release. This research aims to investigate the effect of sitagliptin on white adipose tissue inflammation, adipokine level, metabolic syndrome, and fatty liver through 5' adenosine monophosphate-activated protein kinase (AMPK) pathway.

Tetramethylpyrazine alleviates diabetic nephropathy through the activation of Akt signalling pathway in rats.

In the whole world, the principal cause of end-stage renal disease is diabetic nephropathy (DN), which is one of the most relentless complications of diabetes. However, there is a shortfall of compelling DN treatments and the mechanism potentially able to alleviate renal injury remains ambiguous. In this experiment, we estimated the preventive actions of tetramethylpyrazine (TMP) on DN in rats and further investigated the underlying mechanism.

Tetramethylpyrazine prevents diabetes by activating PI3K/Akt/GLUT-4 signalling in animal model of type-2 diabetes.

Aims: The present experiment was conceptualised to explore the therapeutic response of tetramethylpyrazine (TMP), a major active constituent of Ligusticum chuanxiong, a Chinese traditional medicinal plant, in high-fat diet (HFD)-streptozotocin (STZ)-induced diabetes in rats and to identify the possible mechanism of action.

Main Methods: Dose-reliant effect of oral treatment of TMP (100, 150 and 200 mg/kg/day) for 28 days was evaluated by calculating the alteration in body weight, level of fasting blood glucose (FBG), plasma insulin, homeostasis model assessment (HOMA), serum lipids, oral glucose & intraperitoneal insulin tolerance and glycosylated haemoglobin in HFD-STZ-induced type-2 diabetic (T2D) rats and underlying molecular mechanisms of TMP was also studied.

Key Findings: TMP treatment prominently reduced the level of FBG, glycosylated haemoglobin and revived body weight gain and level of serum insulin dose-dependently in diabetic rats.

Pterostilbene Decreases Cardiac Oxidative Stress and Inflammation via Activation of AMPK/Nrf2/HO-1 Pathway in Fructose-Fed Diabetic Rats.

Purpose: Oxidative stress has a pivotal role in the pathogenesis of diabetes-associated cardiovascular problems, which has remained a primary cause of the increased morbidity and mortality in diabetic patients. It is of paramount importance to prevent the diabetes-associated cardiac complications by reducing oxidative stress with the help of nutritional or pharmacological agents. Pterostilbene (PT), the primary antioxidant in blueberries, has recently gained attention for its promising health benefits in metabolic and cardiac diseases.

Evaluation of the anti-inflammatory effect of an anti-platelet agent crinumin on carrageenan-induced paw oedema and granuloma tissue formation in rats.

The present study was designed to explore the anti-inflammatory activity of an anti-platelet agent crinumin, by various in vitro and in vivo inflammation models. Firstly, crinumin protein was purified through cation exchange chromatography; then, in vitro activity was estimated by albumin denaturation assay and HRBC membrane stabilization assay. Carrageenan-induced paw oedema and cotton pellet-induced granuloma models were used for in vivo anti-inflammatory activity assessment in rats.

Promising therapeutic potential of pterostilbene and its mechanistic insight based on preclinical evidence.

Pterostilbene (PS) is a well-recognized antioxidant that primarily exists in blueberries, grapevines and heartwood of red sandalwood. Interest in this compound has been renewed in recent years, and studies have found that PS possesses an array of pharmacological properties, including chemopreventive, antiinflammatory, antidiabetic, antidyslipidemic, antiatherosclerotic and neuroprotective effects. However, the greater in vivo bioavailability of PS, as compared to resveratrol, is an added advantage for its efficacy.
