Two-way ANOVA analysis found no statistically significant effect of PCOS status on GLUT4 expression (p = 0.1997) nor any statistical interaction between PCOS status and obesity (p = 0.1318), although GLUT4 expression levels were higher in women in the lean control group than in any of the other three groups, as noted for RBP4 (Figure 3B). Here, SLC2A4 is linked to polycystic ovary syndrome.
