Cancer&Entry Information
| Cancer Name | colorectal cancer |
| ICD-0-3 | C19.9 |
| Methods | qPCR, Western blot etc. |
| Sample | cell lines (RNAi-MALAT1-SW480, RNAa-MALAT1-SW480 and Scramble-SW480) |
| Expression Pattern | down-regulated |
| Function Description | We found that MALAT1 interacts with both SRPK1 and SRSF1. MALAT1 increases AKAP-9 expression by promoting SRPK1-catalyzed SRSF1 phosphorylation. Following MALAT1 knockdown, overexpression of SRPK1 was sufficient to restore SRSF1 phosphorylation and AKAP-9 expression to a level that promoted cell proliferation, invasion and migration in vitro. Conversely, SRPK1 knockdown after overexpression of MALAT1 in SW480 cells diminished SRSF1 phosphorylation and AKAP-9 expression and suppressed cell proliferation, invasion and migration in vitro. These findings suggest MALAT1 increases AKAP-9 expression by promoting SRPK1-catalyzed SRSF1 phosphorylation in CRC cells. |
