Single and Combined Aluminium and Cadmium Exposure during Pregnancy Mediate Changes in Cardio Metabolic Indices in Mice

Abstract

The potential risk of Aluminium and Cadmium co-exposure is high owing to evidence of their co-contamination of several food products. Therefore, the present study investigated effect of single and combined exposures of aluminium and cadmium during pregnancy on cardio metabolic changes in mice. Following delivery and at the end of 78 days postnatal development, it was observed that exposure to Al and Cd during pregnancy altered indices of cardiac function via pathways related to angiotensin, cardiac troponin and oxidative stress signalling which may have impacted directly on the histoarchitectural features of the heart. Comparatively, prenatal exposure to Cd alone impacted more negatively to the heart in relation to exposure to either Al only or co-exposure to Al and Cd.
