TET proteins, by converting 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), are hypothesized, but not directly shown, to protect promoter CpG islands (CGIs) against abnormal DNA methylation (DNAm) in cancer. We define such a protective role linked to DNA damage from oxidative stress (OS) known to induce this abnormality. TET2 removes aberrant DNAm(More)
On the basis of Eu(III)-4,7-bis(chlorosulfophenyl)-1,10-phenanthroline-2,9-di-carboxylic acid chelate (BCPDA) that was synthesized and characterized for time-resolved fluoroimmunoassay (TRFIA), Donkey anti-hepatitis B surface (anti-HBs) was labeled with BCPDA-Eu3+. Coomassie Brilliant Blue was used to determine the protein concentration and radio(More)
Metastasis is the major dominant reason for poor prognosis of hepatocellular carcinoma (HCC) after surgical treatment. However, the molecular mechanism of metastasis has not been well characterzied. Here, we report a novel function of Barx homeobox1 (Barx1) in inhibiting HCC invasion and metastasis. Barx1 expression is significantly decreased in human HCC(More)
An oncogenic role for CHD4, a NuRD component, is defined for initiating and supporting tumor suppressor gene (TSG) silencing in human colorectal cancer. CHD4 recruits repressive chromatin proteins to sites of DNA damage repair, including DNA methyltransferases where it imposes de novo DNA methylation. At TSGs, CHD4 retention helps maintain DNA(More)
