Effects of SMC1A mutation and overexpression in vivo. a HCT116 cells, a colorectal cancer cell line with stable karyotype, were stably transfected with both SMC1A wild-type gene and SMC1A c.A2027G mutation. Western blot shows a more marked expression in HCT116 SMC1A wild-type (2) and HCT116 SMC1A c.A2027G (3) when compared with HCT116 cells (1). An antibody against Tubulin was used as loading control. b The effects of HCT116, HCT116 SMC1A wild-type and HCT116 SMC1A c.A2027G cells were analyzed in vivo using an immunocompromised mouse model. Time-dependent analysis shows that HCT116 SMC1A wild-type and HCT116 SMC1A c.A2027G require 11 and 13 days to form tumors. In contrast, the development of tumors peaked after 18 days with HCT116 cells. c Representative images of tumors formed in the mice with HCT116 cells. d Tumors induced by HCT116 SMC1A wild-type. e Tumors formed in the mice in which HCT116 SMC1A c.A2027G cells were implanted. f Change in tumor weight. g Difference in tumor volume after subcutaneous cell inoculation. h Example of representative histopathological examination performed with hematoxylin and eosin staining.
