In the future, it is necessary to expand the sample size and further explore the expression of NRAS-AS in liver cancer, as well as the relationship between NRAS-AS and the regulation of NRAS protein expression in the occurrence and development of liver cancer, in order to elucidate the anti-cancer molecular regulatory mechanisms of antisense RNA NRAS-AS in the process of liver cancer occurrence and development. This evidence concerns the gene NRAS and cancer.
