Interestingly, among genes involved in the maintenance of glucose‐stimulated insulin secretion in MIN6 cell lines identified recently by Yamato et al. (2013), six genes were also found in our study with a changed expression in response to hyperglycemia (cd24a, Iqgap2, Ccnd2, Bach2, Pcdh7, Pqlc3). Here, CCND2 is linked to Hyperglycemia.
