Regulation of Tumor Suppressor p53 and HCT116 Cell Physiology by Histone Demethylase JMJD2D/KDM4D

JMJD2D, also known as KDM4D, is a histone demethylase that removes methyl moieties from lysine 9 on histone 3 and from lysine 26 on histone 1.4. Here, we demonstrate that JMJD2D forms a complex with the p53 tumor suppressor in vivo and interacts with the DNA binding domain of p53 in vitro. A luciferase reporter plasmid driven by the promoter of p21, a cell cycle inhibitor and prominent target g...

Histone Demethylase Jumonji D3 (JMJD3) as a Tumor Suppressor by Regulating p53 Protein Nuclear Stabilization

Histone methylation regulates normal stem cell fate decisions through a coordinated interplay between histone methyltransferases and demethylases at lineage specific genes. Malignant transformation is associated with aberrant accumulation of repressive histone modifications, such as polycomb mediated histone 3 lysine 27 (H3K27me3) resulting in a histone methylation mediated block to differentia...

Tumor suppressor p53: regulation and function.

The p53 protein is a transcription factor involved in maintaining genomic integrity by controlling cell cycle progression and cell survival. Mutations in p53 are the most frequently seen genetic alterations in human cancer. The function of p53 is critical to the way many cancer treatments kill cells because radiotherapy and chemotherapy act in part by triggering programmed cell death in respons...

Regulation of the p53 tumor suppressor protein.

Mutations in the p53 tumor suppressor gene occur in about 50% of all human tumors, making it the most frequent target for genetic alterations in cancer (for recent reviews on p53 see Refs. 1–5). Such mutations probably facilitate carcinogenesis primarily through abrogating the tumor suppressor activities of the wild type p53 protein, although at least some forms of tumor-associated mutant p53 p...

Microbial Regulation of p53 Tumor Suppressor

p53 tumor suppressor has been identified as a protein interacting with the large T antigen produced by simian vacuolating virus 40 (SV40). Subsequent research on p53 inhibition by SV40 and other tumor viruses has not only helped to gain a better understanding of viral biology, but also shaped our knowledge of human tumorigenesis. Recent studies have found, however, that inhibition of p53 is not...
