PPARG and steatosis: Diet-induced steatosis reduced hepatic <i>Pemt</i> expression in control (<i>Pparg</i>-intact) mice, and the thiazolidinedione (TZD)-mediated activation of PPARγ in diet-induced obese control (<i>Pparg</i>-intact) mice reduced the expression of betaine homocysteine S-methyltransferase (<i>Bhmt)</i> and <i>Cbs</i>.
