| ICD-0-3 | C61.9 |
| Methods | qPCR, Western blot, Luciferase reporter assay etc. |
| Sample | cell lines (DU145 and PC3, HEK-293T), PCa tissues |
| Expression Pattern | up-regulated |
| Function Description | MALAT1 expression levels were up-regulated in clinical DTX-resistant PCa samples.Overexpressed MALAT1 promoted cell proliferation,migration and invasion but decreased cell apoptosis rate of PCa cells in spite of DTX treatment.We identified miR-145-5p as a target of MALAT1.MiR-145-5p overexpression in PC3-DTX led to inhibited cell proliferation, migration and invasion as well as reduced chemoresistance to DTX,which was attenuated by MALAT1.Moreover,we determined that AKAP12 was a target of miR-145-5p,which significantly induced chemoresistance of PCa cells to DTX. Besides,it was proved that MALAT1 promoted tumour cell proliferation and enhanced DTX-chemoresistance in vivo. |
