Cancer&Entry Information
| Cancer Name | gastric cancer |
| ICD-0-3 | C16 |
| Methods | qPCR, Western blot etc. |
| Sample | cell lines (SGC7901, BGC823) |
| Expression Pattern | up-regulated |
| Function Description | Chemoresistant GC cells had higher levels of MALAT1 and increased autophagy compared with parental cells. Silencing of MALAT1 inhibited chemo-induced autophagy, whereas MALAT1 promoted autophagy in gastric cancer cells. Knockdown of MALAT1 sensitized GC cells to chemotherapeutics. MALAT1 acts as a competing endogenous RNA for miR-23b-3p and attenuates the inhibitory effect of miR-23b-3p on ATG12, leading to chemo-induced autophagy and chemoresistance in GC cells. |
