GAS5 and cervical cancer: GAS5 and GAS5-AS1 present around 40 complementary nucleotides, responsible for their physical interaction at the 3’ terminal [21], and a previous study showed that GAS5-AS1 overexpression prolonged the half-life of GAS5, whereas GAS5-AS1 silencing reduced the half-life of GAS5 in cervical cancer cells [21].
