Abstract

Purpose

To address the role of ubiquitin-conjugating enzyme, E2C/UbcH10, in astrocytic carcinogenesis.

Methods

Expression pattern of UbcH10 in U251 glioma cells was evaluated by immunohistochemistry and western blot. RNA interference was employed to downregulate UbcH10 expression in U251 cell line. The effect of UbcH10 silencing on cell proliferation was assessed by MTT assay and cell cycle analysis. Cell apoptosis was determined by flow cytometry, TUNEL staining and western blot.

Results

Levels of UbcH10 protein were significantly upregulated in U251 cells compared with normal brain tissues. Marked immunoreactivity for UbcH10 was demonstrated in the cytoplasm of U251 glioma cells, especially in the mitotic cells. The growth rate of U251 cells was significantly inhibited by depletion of UbcH10 by short interference RNA. Further, UbcH10 RNAi induced apoptosis through induction of Bax and p53, downregulation of Bcl-2 and G2/M arrest of the cell cycle.

Conclusion

These data imply that knocking-down UbcH10 protein expression may represent a potential therapeutic option for glioma.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
