Abstract:
Selenium (Se) deficiency induces typical clinical and pathological changes and causes various pathological responses at the molecular level in several different chicken organs; the kidney is one of the target organs of Se deficiency. To explore the mechanisms that underlie the effects of microRNA‐33‐3p (miR‐33‐3p) on Se deficiency‐induced kidney apoptosis, 60 chickens were randomly divided into two groups (30 chickens per group). We found that Se deficiency increased the expression of miR‐33‐3p in the chicken kidney. A disintegrin and metalloprotease domain 10 (ADAM10) was verified to be a target of miR‐33‐3p in the chicken kidney. The overexpression of miR‐33‐3p decreased the expression levels of β‐catenin, cyclinD1, T‐cell factor (TCF), c‐myc, survivin, and Bcl‐2; it increased the expression levels of E‐cadherin, Bak, Bax, and caspase‐3; and it increased the number of chicken kidney cells in the G0/G1 phase. In addition, Se deficiency caused the ultrastructure of the kidney to develop apoptotic characteristics. The results of flow cytometry analysis and AO/EB staining showed that the number of apoptotic chicken kidney cells increased in the miR‐33‐3p mimic group. All these results suggest that Se deficiency‐induced cell cycle arrest and apoptosis in vivo and in vitro in the chicken kidney via the regulation of miR‐33‐3p, which targets ADAM10.
