To support the idea that the DETA/NO-induced inhibition of endometrial cancer cell growth is mediated via RASSF1 and CDKN1A expression, cells transfected with either RASSF1 or CDKN1A-targeted siRNA oligonucleotides were treated with or without DETA/NA for 24 h. This evidence concerns the gene RASSF1 and endometrial cancer.
