This study investigates DNER’s oncogenic function and mechanisms in gastric cancer. RNA-Seq analysis of TCGA gastric tumor data links DNER expression to advanced pathology and patient prognosis. DNER levels increase in stem cell-enriched cancer spheroids; DNER knockdown suppresses proliferation and invasion, triggers apoptosis, enhances chemosensitivity, and reduces spheroid formation. DNER silencing elevates p53, p21cip/waf, and p27 and shifts cells into G1 phase, while restoring p21 partially rescues viability and S-phase progression. Notch signaling through NICD counteracts DNER-silencing effects, supporting Notch activation by DNER. TGF-β signals contribute to DNER expression in both culture conditions, suggesting a pathway connection.

This study aimed to investigate the oncogenic role of DNER and the mechanisms behind its oncogenic role in gastric cancer. Analysis of the RNASeq data of gastric cancer tissues obtained from the TCGA database revealed that the expression of DNER was associated with the pathology of advanced gastric cancer and the prognosis of patients. DNER expression was increased upon stem cell-enriching cancer spheroid culture. Knockdown of DNER expression inhibited cell proliferation and invasion, induced apoptosis, enhanced chemosensitivity, and decreased spheroid formation of SNU-638 gastric cancer cells. DNER silencing elevated the expression of p53, p21cip/waf, and p27, and increased G 1 phase cells at the expense of S phase cells. Knockdown of p21cip/waf expression in the DNER-silenced cells partially restored cell viability and S phase progression. DNER silencing also induced the apoptosis of SNU-638 cells. While both cleaved caspases-8 and 9 were detected in adherent cells, only cleaved caspase-8 was found to have increased in spheroid-cultured cells, suggesting a distinct activation pattern of caspase activation depending on the growth condition. Knockdown of p53 expression rescued the DNER-silenced cells from apoptosis and partially restored cell viability. In contrast, overexpression of the Notch intracellular domain (NICD) decreased the expression of p53, p21cip/waf, and cleaved caspase-3 in DNER-silenced cells. Moreover, NICD expression fully reverted the cell viability reduction, arrest in the G 1 phase, and elevated apoptosis caused by DNER silencing, thereby suggesting activation of Notch signaling by DNER. Expression of a membrane-unbound mutant of mDNER also decreased cell viability and induced apoptosis. On the other hand, TGF-􀀌 signals were found to be involved in DNER expression in both adherent and spheroid-cultured cells. DNER could therefore be a link connecting TGF-􀀌 signaling to Notch signaling.
