Fig. 4From: Developmental programming of obesity by maternal exposure to concentrated ambient PM2.5 is maternally transmitted into the third generation in a mouse modelThe adipose expression levels of leptin mRNA. Total RNAs were extracted from the epididymal adipose tissues of the indicated male offspring, and the expression levels of leptin mRNA were determined by qPCR. n = 12 and 18 (a); 18 and 28 (b); 11 and 19 (c); 15 and 19 (d). *p < 0.05 versus FA, student t testBack to article page
