Arsenic unsettles the cerebellar balance between neurodegeneration and neurogenesis: reversal by folic acid.

Arsenic-mediated neurodegenerative disorders affect millions of individuals globally, but the specific impact of environmental arsenic on adult cerebellar degeneration and neurogenesis is incompletely understood. Of particular concern is arsenic-induced apoptosis-driven neurodegeneration. Our major objective was to investigate the molecular signaling intricacies associated with arsenic-induced death of cerebellar neurons and to propose folic acid as a possible intervention.

Arsenic-induced transition of thymic inflammation-to-fibrosis involves Stat3-Twist1 interaction: Melatonin to the rescue.

Groundwater arsenic is a notorious toxicant and exposure to environmentally relevant concentrations persists as a healthcare burden across the world. Arsenic has been reported to jeopardize the normal functioning of the immune system, but there are still gaps in the understanding of thymic T cell biology. Immunotoxic influence of arsenic in thymic integrity demands a potent restorative molecule.

Metformin instigates cellular autophagy to ameliorate high-fat diet-induced pancreatic inflammation and fibrosis/EMT in mice.

Background: Chronic pancreatic dysfunction is frequently observed as a consequence of prolonged high-fat diet consumption and is a serious public health concern. This pro-diabetic insult aggravates inflammation-influenced fibrotic lesions and is associated with deregulated autophagy. Metformin, a conventional anti-hyperglycemic drug, might be beneficial for pancreatic health, but the complex molecular regulations are not clarified.

An integrated strategy to explore the potential role of melatonin against copper-induced adrenaline toxicity in rat cardiomyocytes: Insights into oxidative stress, inflammation, and apoptosis.

Aims: Circumstantial anxiety as well as chronic stress may stimulate the release of stress hormones including catecholamines. Adrenaline toxicity has been implicated in many cardiovascular conditions. Considering previous literature that suggests the oxidative potential of the adrenaline-copper entity, we have investigated its potential nocuous role in isolated adult rat cardiomyocytes, the underlying molecular mechanism, and its possible protection by melatonin.

Arsenic-induced differential inflammatory responses in mouse thymus involves NF-κB/STAT-3 disruption, Treg bias and autophagy activation.

Aim: Arsenic contamination in drinking water is a world-wide public health concern. Sustained arsenic ingestion leads to immune alterations and subsequent development of inflammatory and autoimmune diseases; however, the underlying cellular and molecular intricacies of immunotoxicity remains uncharacterized. We aim to understand how exposure to arsenic at different concentrations affects the immune system differentially and whether arsenic-induced differential inflammation dictates altered T-regulatory cell bias and emphasize the role of autophagy in the pathway.
