Abstract

Human giant larvae‑1 (Hugl‑1) is a human homologue of Drosophila tumor suppressor lethal (2)‑giant larvae and has been reported to be involved in the development of human malignancies. Previous studies performed by our group demonstrated that Hugl‑1 inhibits glioma cell proliferation in an intracranial model of nude mice. However, the exact molecular mechanisms underlying the participation of Hugl‑1 in glioma invasion and migration, and in the depolarizing process remain largely unknown. Utilizing the U251‑MG cells with stable expression of Hugl‑1, the present study used wound healing, Transwell invasion and western blot assays to explore the role and specific mechanism of Hugl‑1 in glioma invasion and migration. The results of the present study demonstrated that overexpression of Hugl‑1 decreased cell‑cell adhesion and increased cell‑cell extracellular matrix adhesion. In addition, overexpression of Hugl‑1 promoted pseudopodia formation, glioma cell migration and invasion. The molecular mechanism of action involved the negative regulation of N‑cadherin protein levels by Hugl‑1. Overexpression or knockdown of N‑cadherin partially suppressed or enhanced the effects of Hugl‑1 on glioma cell migration and invasion, respectively. Furthermore, Hugl‑1 inhibited cell proliferation, while promoting cell migration, which suggests that it may serve a two‑sided biological role in cellular processes. Taken together, these results suggest that Hugl‑1 promotes the migration and invasion of malignant glioma cells by decreasing N‑cadherin expression. Thus, Hugl‑1 may be applied in the development of targeted and personalized treatment.
