UHRF2 mRNA expression is low in malignant glioma but silencing inhibits the growth of U251 glioma cells in vitro.

UHRF2 is a member of the ubiquitin plant homeo domain RING finger family, which has been proven to be frequently up-regulated in colorectal cancer cells and play a role as an oncogene in breast cancer cells. However, the role of UHRF2 in glioma cells remains unclear. In this study, we performed real-time quantitative PCR on 32 pathologically confirmed glioma samples (grade I, 4 cases; grade II, 11 cases; grade III, 10 cases; and grade IV, 7 cases; according to the 2007 WHO classification system) and four glioma cell lines (A172, U251, U373, and U87).

Orthotopic model of SHG-44 in the enhanced green fluorescent protein nude mouse.

Naturally fluorescent proteins have been widely used in biological research. In this study, we found that the simple and effective way to obtain enhanced green fluorescent protein (EGFP) nude mice is to cross transgenic EGFP C57BL/6J mice with nude (nu/nu) mice. EGFP expression is identified by tail genotyping.

A novel gene RNF138 expressed in human gliomas and its function in the glioma cell line U251.

Background: The gliomas represent the most common primary malignant brain tumors; however, little is known about the molecular pathogenesis of these tumors. Recent research reveals that the oncogenesis and development of gliomas have a close relation to the overexpression of several oncogenes and the inactivation of tumor suppressor genes. Whether the RING finger protein, RNF138, a newly discovered protein, plays a role in glioma oncogenesis is unknown.
