Values are presented as mean ± SD. Different symbols denote values that are significantly different from the control group (Ctrl): * significantly different from Ctrl (p < 0.05 or less); ^a significantly different from the flaxseed oil (FSO) group (p < 0.05 or less); ^b significantly different from the trimethyltin (TMT) group (p < 0.05 or less); SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids.
