Cancer&Entry Information
| Cancer Name | colorectal cancer |
| ICD-0-3 | C19.9 |
| Methods | qPCR, FISH etc. |
| Sample | CRC tissues, cell lines (FBS, DLD-1, HCT-15 etc.) |
| Expression Pattern | differential expression |
| Function Description | In the cell lines, methylation status at the KvDMR1 correlated well with LIT1 expression profiles. Loss of expression of LIT1 also correlated with enrichment of H3 lysine 9 (H3-K9) dimethylation and reduction of H3 lysine 4 (H3-K4) dimethylation. Thus, LIT1 expression appears to be controlled by epigenetic modifications at the KvDMR1, although CDKN1C expression, which is considered to be controlled by LIT1, was not associated with epigenetic status at the KvDMR1 in some colorectal cancer cell lines. Therefore, these findings suggest that LOI of LIT1 via epigenetic disruption plays an important role in colorectal carcinogenesis, but it is not necessarily associated with CDKN1C expression. |
