inhibitor 组的细胞周期被促进(P < 0.05);siFAT1+ 逆转了过表达circFAT1对细胞周期的促进作用(P <
miR⁃181d⁃5p inhibitor 组逆转了 siFAT1+IC#1 组和 0.05,图5)。类似地,miR⁃199a⁃5p inhibitor 促进细胞
siNC+miR⁃181d⁃5p inhibitor 组对细胞周期的调控作 周期进展,且部分逆转siFAT1对细胞周期的阻滞作
用(P < 0.001,图5)。过表达circFAT1缩短了SCC⁃25 用,miR⁃199a⁃5p mimic 则诱导了 SCC⁃25 细胞的
细胞的 G0/G1 期并相对的延长了 S 期,miR⁃181d⁃5p G0/G1 期阻滞,且部分逆转了过表达 circFAT1 对细
