Protective Effects of Inorganic and Organic Selenium on Heat Stress in Bovine Mammary Epithelial Cells

Figure 1

Selenite methionine (SM) and sodium selenite (SS) have protective effects on high-temperature shock-induced cell viability decrease in MAC-T cells. (a) Cell viability of MAC-T cells treated with 42.5°C for 1 h (heat treatment, HT) and then recovered at 37°C for indicated time periods. The control (CON) group was continuously cultured at 37°C without heat treatment. (b) Cell viability of MAC-T cells treated with indicated concentrations of SM and SS for 2 h and then cultured in normal medium for another 12 h. The control group had no SS or SM treatment. (c) Cell viability of MAC-T cells pretreated with indicated concentrations of SM and SS for 2 h, followed by HT and recovery for 12 h. # means significant difference between the SS group and the CON group (b) or between the SS group and the HT group (c). means significant difference between the HT group and the CON group (a), between the SM group and the CON group (b), or between the SM group and the HT group (c). , , ; , , .
