Zinc finger with KRAB and SCAN domain 3 (ZKSCAN3) is associated with cell differentiation, cell proliferation and apoptosis, which has been reported as a critical driver of colorectal cancer. However, the mechanism and function of ZKSCAN3 in colorectal cancer is still unclear. Here, our objective is to identify the functional molecules and signaling by analyzing the RNA-seq data. The GSE172201 was created by the Illumina NovaSeq 6000 (Homo sapiens). The KEGG and GO analyses indicated the immune defense response to virus and transcription activity are major processes in the ZKSCAN3 KO colorectal cancer cells. Moreover, we determined ten key molecules including STAT1, MX1, DDX58, PPARG, EGFR, APP, BST2, DLG4, OASL, and IFIT2. Therefore, our study may provide the novel knowledge of ZKSCAN3 mediated colorectal cancer.

Objective: To assess whether miR-203 regulates DJ-1 expression, affects colorectal cancer cells through PTEN-PI3K/AKT signaling. Methods: Colorectal cancer (CRC) tissues and adjacent tissues were collected followed by analysis of the level of miR-203, DJ-1 and PTEN. miR-203 and DJ-1 level was measured in HCT116, SW480 and normal colorectal cell NCM460. miR-203 mimic or miR-NC was transfected into HCT116 or SW480 cells followed by measuring the level of miR-203, DJ-1, PTEN, p-AKT as well as cell apoptosis and proliferation. Results: Compared with tumor adjacent tissues, tumor tissues showed significantly lower level of miR-203 and PTEN, and higher level of DJ-1. There is a targeted relationship between miR-203 and DJ-1. Compared with NCM460 cell, HCT116 and SW480 cells displayed significantly lower miR-203 level and higher DJ-1 expression. miR-203 mimic significantly reduced DJ-1 and p-AKT level, increased PTEN expression, cell apoptosis and inhibited cell proliferation. Conclusion: Lower miR-203 and higher DJ-1 level is found in CRC patients. Upregulation of miR-203 inhibits DJ-1 expression, increases PTEN expression, impairs PI3K/AKT signaling, inhibits CRC cell proliferation and promotes apoptosis.
