ZNF667-AS1, a positively regulating MEGF10, inhibits the progression of uveal melanoma by modulating cellular aggressiveness.

Zinc finger protein 667-antisense RNA 1 (ZNF667-AS1) is a member of the C2 H2 zinc finger protein family. However, the exact effect of ZNF667-AS1 in uveal melanoma (UM) progression has not been elucidated. The biological roles of ZNF667-AS1 and MEGF10 were assessed using cell counting kit-8 and flow cytometry. Quantitative reverse-transcription polymerase chain reaction and Western blot analyses were conducted to measure the expression of subjects. ZNF667-AS1 expression was significantly decreased in metastasized UM tissues and its low expression was related to poorer prognosis of UM patients. MEGF10 expression was positively associated with ZNF667-AS1 expression. The inhibitory effect of ZNF667-AS1 overexpression on UM cellular malignant behaviors could be reversed by MEGF10 knockdown, which was re-ascertained by the detection of corresponding protein levels (p53, cyclin D1, Bcl-2, and Bax). In conclusion, ZNF667-AS1 might play an inhibitory role in the development of UM by regulating cellular aggressiveness, which was partially realized by positively regulating MEGF10.
