Detection of autophagy-Ca²⁺ homeostasis-related genes in small intestine tissue. The expression of autophagy-Ca²⁺ homeostasis related genes at (A) mRNA and (B) protein levels in small intestine tissue of the control and selenium-deficient groups, respectively. The ∗ indicates significant differences (∗P < 0.05, ∗∗P < 0.002, ∗∗∗P < 0.0002, ∗∗∗∗P < 0.0001) between the 2 groups, and the data are presented as the mean ± SD (n = 6). LC3 = microtubule-associated proteins; ATG = autophagy-related protein; mTOR = mammalian target; CAMKK-β = calmodulin-dependent protein kinase kinase β; AMPK = adenosine 5′-monophosphate-activated protein kinase; SERCA = sarco(endo)plasmic reticulum Ca²⁺-ATPase.
