Parkinson’s disease (PD) is a complex neurodegenerative disorder featuring both motor and nonmotor symptoms associated with progressive loss of dopaminergic neurons in the substantia nigra pars compacta. Oxidative stress (OS) has been implicated pathogenesis PD. Genetic environmental factors can produce OS, which as core contributor to initiation progression PD through degeneration neurons. The transcription factor nuclear erythroid 2-related 2 (Nrf2) orchestrates activation multiple protective genes, including heme oxygenase-1 (HO-1), protects cells from OS. Nrf2 also shown exert anti-inflammatory effects modulate mitochondrial function biogenesis. Recently, series studies have reported that different bioactive compounds were be able activate Nrf2/antioxidant response element (ARE) ameliorate PD-associated neurotoxin, animal models tissue culture.

The term ferroptosis refers to a peculiar type of programmed cell death (PCD) mainly characterized by extensive iron-dependent lipid peroxidation. Recently, has been suggested as potential new strategy for the treatment several cancers, including breast cancer (BC). In particular, among BC subtypes, triple negative (TNBC) is considered most aggressive, and conventional drugs fail provide long-term efficacy. this context, our study's purpose was investigate mechanism in lines reveal significance heme oxygenase (HO) modulation process, providing biochemical approaches. HO's effect on evaluated MTT tests, gene silencing, Western blot analysis, measurement reactive oxygen species (ROS), glutathione (GSH) hydroperoxide (LOOH) levels. order assess implication, different approaches were exploited, using two distinct HO-1 inducers (hemin curcumin), well-known HO inhibitor (SnMP) selective HO-2 inhibitor. data obtained showed contribution onset ferroptosis; induction seemed accelerate process. Moreover, results suggest role erastin-induced ferroptosis. view above, can offer novel approach treatment.

Ulcerative colitis is a common type of inflammatory bowel disease that affects millions individuals around the world. Traditional UC treatment has focused on suppressing immune responses rather than treating underlying causes UC, which include oxidative stress, inflammation, and microbiota dysbiosis. Diosmin (DIO), naturally occurring flavonoid, possesses antioxidant anti-inflammatory properties. This study aimed to assess efficacy DIO in dextran-sulfate sodium (DSS)-induced colitis, investigate some its mechanisms, with an emphasis Akkermansia muciniphila abundance, markers, intestinal barrier function. C57BL/6 mice were given 4% (w/v) DSS induce colitis. DSS-induced administered (100 200 mg/kg) or sulfasalazine orally for 7 days. Every day, activity index (DAI) was determined by recording body weight, diarrhea, bloody stool. Changes fecal A. colonic MUC1 MUC2 expression, as well stress markers all assessed. Histopathological changes, PIK3PR3 ZO-1 levels, immunohistochemical examinations occludin claudin-1, investigated. administration resulted dose-dependent decrease DAI, increase abundance expression while decreasing expression. also dramatically reduced inflammation regulating NF-κB Nrf2 cascades, restored integrity inhibiting PIK3R3 inducing ZO-1, improved occludin/claudin-1 gene immunostaining. provides first evidence preserves increases However, more research required explore impact overall composition diversity gut microbiota.

Background/Objective Cadmium (Cd) is an extremely toxic heavy metal and environmental toxicant, which leads to renal damage by causing oxidative stress. Rhamnazin (RAM) a novel flavonoid, possesses multiple pharmacological activities. Therefore, the present study was planned determine nephroprotective effects of RAM against Cd-prompted toxicity in rats. Methodology In this investigation, 24 male albino rats were distributed into four equal groups, i.e., control, CdCl 2 -intoxicated group (2 mgkg −1 ), + RAM-treated 20 RAM-only treated (20 ). After oral dose administration for 30 days, alterations Nrf2/Keap1 pathway, Cd concentration, antioxidant profile, stress markers, function inflammatory apoptotic kidney histology analyzed. Result The results current revealed that exposure significantly ( P < .05) increased Keap1 expression, while decreasing expressions Nrf2 genes level total status (TAS).
