Upregulation of E2F transcription factor 3 is associated with poor prognosis in hepatocellular carcinoma.

E2F transcription factor 3 (E2F3), a member of the E2F transcription factor family and a member of the genes involved in the regulation of cell cycle, is an oncogene with strong proliferative potential. E2F3 is involved in many processes and plays important roles in the development of several types of cancer, while its relationship with prognosis in hepatocellular carcinoma (HCC) has yet to be ...

Transcription factor E2F binds DNA as a heterodimer.

E2F is a mammalian transcription factor that appears to play an important role in cell cycle control. DNA affinity column-purified E2F from HeLa cells reproducibly exhibits multiple protein bands when analyzed by SDS/PAGE. After electrophoretic purification, electroelution, and refolding of the individual protein components, the E2F DNA binding activity of the individual proteins was poor. Howe...

Implication of transcription factor E2F in regulation of DNA replication.

The transcription factor E2F plays crucial roles in induction of S phase in mammalian cells by regulating the expression of genes that encode molecules involved in cell cycle progression. E2F exerts a repressive effect on E2F-responsive genes in G0/G1 phase by associating with the retinoblastoma tumor suppressor gene product pRb and the related protein p130. This repression is relieved by phosp...

pRB, p107 and the regulation of the E2F transcription factor.

Small DNA tumor viruses, such as adenovirus, encode proteins that deregulate the cell cycle. These proteins are potent transforming agents when tested in standard oncogenic assays. For adenovirus the best characterized viral oncoproteins are the early region 1A (E1A) products. Mutational studies have shown that E1A's oncogenic ability is determined primarily by its ability to bind to certain ce...
