Abstract:
To clarify the role of GATA transcription factors in ovarian carcinogenesis, we analyzed the expression and methylation states of GATA-4/-5/-6 in eight human ovarian cancer cell lines. GATA-4/-5 were methylated in three and two cell lines without their expression, respectively. Methylation of GATA-4/-5 was also detected in nine and five of 15 primary ovarian cancers, respectively. GATA-6 was not methylated in any cases. We transiently over-expressed GATA-5 in the JHOC-5 cell line using an adenovirus system, resulting in that apoptosis was induced and apoptosis-related genes, such as Apaf-1, were up-regulated. These data suggest that GATA-4/-5 may be involved in ovarian carcinogenesis.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Combinatorial Gene Control
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
