Abstract

Background: Gastric cancer (GC) ranks fifth among all common malignancies globally. Genetic research has revealed several genes that are frequently dis-regulated in GC, such as lysine-specific demethylase 6A (KDM6A) and cadherin-1 (CDH1).

Objective: This study aimed to examine the expression profile and role of KDM6A in GC, as well as the molecular pathway involved.

Methods: The expression profile and overall survival data of KDM6A were retrieved from the TCGA database. Expression levels of KDM6A were also measured in GC patient samples and compared with those of healthy controls. Furthermore, stable silencing of KDM6A was introduced into the GC cell line NCI-N87, followed by assessments of cell proliferation, migration and invasion, in the xenograft mouse model. The metastatic status of mice injected with NCI-N87 cells was also analyzed.

Results: In patients diagnosed with GC, KDM6A was upregulated. Silencing KDM6A reduced the proliferation, migration and invasion of cells, as well as the growth of xenograft tumors. KDM6A knockdown also inhibited metastatic behaviors of injected NCI-N87 cells, as well as elevated CDH1 expression, leading to reversed epithelial-mesenchymal transition.

Conclusion: KDM6A serves as an oncogene in GC and exerts its pro-tumor functions by repressing the expression of CDH1.

Keywords: KDM6A, CDH1, gastric cancer, metastasis, NCI-N87 cells, oncogene.
