INS and gestational diabetes: 29 miRNAs ↑ in GDM patients compared to controlsmiR-19a, miR-142, miR-143, miR-340, miR-7g, and miR-19b were selected for external q-PCR validation. miR-340 was found at ↑ levels in GDMPAIP1, a downstream target was significantly ↓ in GDM.The 4 miRNAs positively associated with BMI were unrelated to GDM.↑ insulin or ↓ glucose reduced miR-340 expression.
