Numerous biological processes are governed by the biological clock. Studies using Drosophila melanogaster (L.) are valuable that could be of importance for their effective applications on rodent studies. In this study, the beneficial role of quercetin (a flavonoid) on H2O2 induced stress in D. melanogaster was investigated. D. melanogaster flies were divided into four groups (group I - control, group II - H2O2 (acute exposure), group III - quercetin, and group IV - quercetin + H2O2 treated). Negative geotaxis assay, oxidative stress indicators (protein carbonyls, thiobarbituric reactive substances [TBARS]), and antioxidants (superoxide dismutase [SOD], catalase [CAT], glutathione-S-transferase [GST], glutathione peroxidase, and reduced glutathione [GSH]) were measured at 4 h intervals over 24 h and temporal expression of heat shock protein-70 (Hsp70), Upd1 (homolog of IL-6 in Drosophila), and nitric oxide synthase (Nos) was analyzed by Western blotting...

Aluminium (Al) is a ubiquitously distributed environmental toxicant that lacks biological functions; however, its accumulation in the brain has been demonstrated to be linked to several neuropathological conditions particularly Alzheimer's disease (AD). Asiatic acid (AA), a triterpene extracted from Centella asiatica, has been reported to cross the blood brain barrier and also displayed antioxidant and neuroprotective activities. The present study was aimed to explore the neuroprotective effect of AA against aluminium maltolate (Al(mal)3) induced neurotoxicity by assessing cell viability, mitochondrial membrane potential, levels of reactive oxygen species (ROS), DNA damage and apoptosis (Hoechst and dual staining, comet assay; expressions of pro-apoptotic, anti-apoptotic and signaling indices) via AKT/GSK-3β signaling pathway in SH-SY 5Y  neuroblastoma cells...

Prostate cancer is the third leading cause of death by cancer in men. Surgery or hormone deprivation usually contains the progression of the local forms of the disease. In metastatic situations, chemotherapy or second generation hormone therapies are used with an overall survival that never exceeds 36 months when tumors become resistant to castration. In the search for new alternatives, clinical trials with various classes of anticancer drugs have been performed, including chemotherapies, targeted therapies with kinase inhibitors, radium-223, or immunotherapies with somehow limited efficacy...

Osteoimmunology is an interdisciplinary research field which combines the existing fields of osteology (bone biology) and immunology under one umbrella. The observation that contributed enormously to the emergence of osteoimmunology as an independent field of investigation was the enhanced bone loss in various inflammatory bone diseases such as rheumatoid arthritis, osteoporosis and periodontitis. T helper cells (Th1, Th2, Treg and Th17) along with various other immune cells (B cells, DC, macrophages etc.) are actively involved in bone homeostasis...

Adipose tissue represents a large volume of biologically active tissue that exerts substantial systemic effects in health and disease. Alcohol consumption can profoundly disturb the normal functions of adipose tissue by inducing adipocyte death and altering secretion of adipokines, pro-inflammatory mediators and free fatty acids from adipose tissue, which have important direct and indirect effects on the pathogenesis of alcoholic liver disease (ALD). Cessation of alcohol intake quickly reverses inflammatory changes in adipose tissue, and pharmacological treatment that normalizes adipose tissue function improves experimental ALD...

The breadth of applications of nanoparticles and the access to food-associated consumer products containing nano-sized materials lead to oral human exposure to such particles. In biological fluids nanoparticles dynamically interact with biomolecules and form a protein corona. Knowledge about the protein corona is of great interest for understanding the molecular effects of particles as well as their fate inside the human body. We used a mass spectrometry-based toxicoproteomics approach to elucidate mechanisms of toxicity of silver nanoparticles and to comprehensively characterize the protein corona formed around silver nanoparticles in Caco-2 human intestinal epithelial cells...
