Meanwhile, we also evaluated host genes of the seven validated circRNAs (Table 2), including abnormal spindle-like microcephaly (ASPM), marker of proliferation Ki-67, (MKI67), trophinin-associated protein (TROAP, also named TASTIN), WD repeat domain 62 (WDR62), kinesin family protein 14 (KIF14), and V-Myb avian myeloblastosis viral oncogene homolog-like 2 (MYBL2) using qPCR. This evidence concerns the gene MKI67 and microcephaly.
