Our findings reveal a correlation between low ALDH2 expression and the progression as well as poor prognosis of ESCC. Additionally, ESCC cell apoptosis was stimulated while ESCC cell proliferation, migration, invasion, and angiogenesis were all successfully suppressed by ALDH2 overexpression. Regarding the molecular mechanism, ALDH2 was observed to suppress NOTCH1, which in turn inhibited the PI3K/Akt pathway, thereby hindering the expression of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor A (VEGFA), which are both linked to angiogenesis, and ultimately exerting its inhibitory effect on ESCC through this regulatory cascade. Importantly, we established a subcutaneous xenograft tumor model in BALB/c nude mice using ESCC cell lines with ALDH2 overexpression. Our results demonstrated that ALDH2 overexpression significantly inhibited tumor growth and angiogenesis, further supporting ALDH2 as a potential therapeutic target in ESCC.

Importantly, persistent overexpression of TRIM10β is recognized as a proteotoxic burden and rapidly degraded via the unfolded protein response (UPR) under cellular stress, thereby serving as a protective mechanism.
