ZNF326 promotes proliferation of non-small cell lung cancer cells by regulating ERCC1 expression

Laboratory Investigationvolume 99pages169179 (2019) | Download Citation


The roles and downstream target genes of the transcription factor ZNF326 in malignant tumors are unclear. Out of 146 lung cancer tissue samples, we found that high expression of ZNF326 in 82 samples was closely related to low differentiation and a high pTNM stage of non-small cell lung cancer (NSCLC) cells. In vitro and in vivo analyses showed that ZNF326 significantly promoted cell cycle progression, colony formation, and proliferation as well as the growth of NSCLC transplanted tumors. Chromatin immunoprecipitation sequencing, dual-luciferase assay, and electrophoretic mobility shift assay confirmed that the C2H2 structure of ZNF326 binds to the −833 to −875 bp region of the ERCC1 promoter to initiate transcriptional activity. This binding promoted CyclinB1 synthesis and cell cycle progression. These results show that the ZNF326 transcription factor is highly expressed in lung cancer and promotes the proliferation of NSCLC cells by regulating the expression of ERCC1.
