FLOT2 and colorectal carcinoma: In this study, an interference carrier of FLOT2 was constructed with RNA interference technology to explore the expression of siRNA carried by PLL-modified silicon nanoparticles in CRC cells, so as to explore the influence of FLOT2 gene on the invasion and metastasis of CRC and its corresponding molecular mechanism and provide a certain scientific basis for the clinical treatment and prognosis analysis of CRC.
