Cancer&Entry Information
| Cancer Name | cervical cancer |
| ICD-0-3 | C53 |
| Methods | qPCR, RNAi, Western blot, Luciferase reporter assay, Flow cytometry assay etc. |
| Sample | HR-HPV+ cervical cancer tisssue, cell lines (HeLa, CaSki, SiHa) |
| Expression Pattern | up-regulated |
| Function Description | Findings of this study confirmed higher MALAT1 expression in HR-HPV (+) cervical cancer. Knockdown of endogenous MALAT1 significantly reduced cell growth rate and invasion and increased cell apoptosis of Hela and siHa cells. Besides, knockdown of MALAT1 increased the expression of miRNA-124, while ectopic expression of miR-124 decreased MALAT1 expression. MALAT1 can indirectly modulate GRB2 expression via competing miR-124. Knockdown of GRB2 reduced cell invasion and increased cell apoptosis. In conclusion, MALAT1 can promote HR-HPV (+) cancer cell growth and invasion at least partially through the MALAT1-miR-124-RBG2 axis. |
