Temporin-SHf is a linear, ultra-short, hydrophobic, α-helix, and phe-rich cationic antimicrobial peptide. The antitumor activities and mechanism of temporin-SHf-induced cancer cell death are unknown. The temporin-SHf was synthesized by solid-phase Fmoc chemistry and antimicrobial and antitumor activities were investigated.

Background: Tigerinins are antimicrobial peptides (AMPs) derived from the skin secretions of the Indian bullfrog Hoplobatrachus tigerinus.
Methods: Tigerinin-1 (FCTMIPIPRCY-Am) peptide was synthesized by solid-phase Fmoc chemistry and investigated its antitumor activities.
Results: Tigerinin-1 was cytotoxic to human cancer cells.
Nardostachys jatamansi (D. Don) DC. is an essential plant used in Indian Ayurveda to treat neurological disorders, and it enhances memory.

Pb neurotoxicity has been linked to various human diseases, but its associated mechanism causing neurotoxicity is unknown. Drosophila melanogaster as a model organism has been used to study the mechanism involved in Pb-caused neurotoxicity and the potential role of antioxidants in ameliorating its harmful effects.

Even though the exact aetiology of ASD remains unknown, studies have shown a link between genetics and environmental pollutants. Heavy metal lead (Pb), the environmental pollutant, is associated with ASD.

Epigenetic alterations such as DNA methylation and histone modifications play vital role in AFB-mediated carcinogenesis. These epigenetic modifications may result in the recruitment of specific proteins and transcription factors to the promoter region and regulate gene expression.

Applying the single-cell gel electrophoresis (comet) assay, we show that the widely used organophosphorus pesticide malathion is cytotoxic, genotoxic, and induces oxidative stress in human lymphocytes.
View Article and Find Full Text PDFBackground: Malathion is the most widely used organophosphate pesticide in agriculture. Increasing cancer incidence in agricultural workers and their children links to the exposure of malathion. Identification of genes involved in the process of carcinogenesis is essential for exploring the role of malathion.

Third instar larvae derived from the ST or HB crosses were reared in sub lethal concentrations of lead acetate (PbAc) treated food media and showed that Pb was readily taken up and accumulated in the said crosses. Pb modulated heme synthesis was evident by significant reductions of δ-aminolevulinic acid dehydratase (δ-ALA-D) and cytochrome P450 (CYP450) and increased accumulation of δ-aminolevulinic acid (δ-ALA).
