NEAT1 and colorectal cancer: As found, the expression level of NEAT1 increased in CRC samples in contrast with NAT samples (Figure 1A), complying with previous researches conducted on CRC tissues.16 To validate the vital role of NEAT1 in CRC tissue and cell line, we examined the impact exerted by artificially decreasing NEAT1 on colorectal cancer cell proliferation with NEAT1 siRNA.
