A: expression of miR-29 family in the offspring heart at postnatal day (PND) 21 (N = 8; all male) from control group and perinatal nicotine exposure group. B: sequence alignments with the coordinated positions of miR-29 family with myocardial infarction-associated transcript (MIAT). C: expression of MIAT in the offspring heart at PND21 (N = 8; all male). Results are presented as box-and-whisker plot and were analyzed using unpaired t test (*P < 0.05). Thin horizontal lines within boxes are medians, cross symbols are mean values, and whiskers indicate maximum and minimum values. PPIA, peptidylprolyl isomerase A.
