Abstract
Date (Phoenix dactylifera L.) seeds (PDL) have recently evoked significant attention for their therapeutic potential against numerous diseases. Aflatoxin B1 (AFB1) is an inevitable environmental hazard that pollutes foods and may harm the heart. This study investigated the beneficial effect of PDL against cardiac toxicity induced by AFB1 in male offspring. Female albino rats received PDL (200 mg/kg) orally for 14 days before mating till weaning and AFB1 (50 μg/kg) intramuscularly throughout gestation and lactation. At postnatal day 60, male offspring hearts were collected. Compared to AFB1 intoxicated group, PDL-treated offspring displayed improved cardiac biomarkers, an increase in their antioxidant defense, and a decrease in the cardiac proinflammatory cytokines. Additionally, a reduction in the expression levels of Bcl2 and Nrf2 was observed, with genes linked to increased cardiac caspase-3, Bax, ACE1, P53, and cytochrome C levels. In conclusion, PDL acts as a potential adjuvant agent for ameliorating cardiac toxicity and apoptosis resulting from exposure to AFB1. This is attributed to its antioxidative and anti-inflammatory effects, as well as its capacity to sequester free radicals within cardiac tissue.
