Fig 1: Average CTRP15 mRNA expression and protein secretion. The fixed effect results are listed at the bottom of each figure. (a) mRNA of undifferentiated and differentiated BSC3 vs. BSC11; (b) mRNA of undifferentiated vs. differentiated BSC3 and undifferentiated vs. differentiated BSC11; (c) proteins of undifferentiated and differentiated BSC3 vs. BSC11; (d) proteins of undifferentiated vs. differentiated BSC3 and undifferentiated vs. differentiated BSC11. The mRNA is in relative abundance and normalized to 18S ribosomal RNA. Whiskers represent 1.5 times the interquartile range, and * represents a trend; ** represents significance. Figures report the means of three repeated measures; BSC3 came from three-month-old steers (n = 3); and BSC11 came from 11-month-old steers (n = 3).
