In contrast to our previously reported decreases in expression of mRNAs encoding some contractile proteins in idiopathic gastroparesis subjects compared to high BMI control subjects [9], when compared to low BMI transplant donor controls, idiopathic gastroparesis subjects had elevated levels of mRNAs encoding MYH11, ACTA2 and MYLK1 (Fig. 2). Here, MYH11 is linked to gastroparesis.
