FADS1 and ovarian cancer: Consistent with previous findings that miR-1908 is regulated by its own transcription unit rather than co-regulated with its host gene FADS1 [34], we found that expressions of miR-1908 and FADS1 are negatively correlated/uncorrelated in glioblastoma and ovarian cancer (R = −0.12, 0.01; FDR = 0.01, 0.87).
