Abstract:
In this study we investigated the types and role of different genetic changes of PTCH1 gene in three different types of ovarian tumors: carcinomas, fibromas and dermoids. LOH of the PTCH1 region was detected in 27.3% ovarian carcinoma samples, 18.18% ovarian fibroma samples and 55.56% ovarian dermoid samples. No point mutations were detected in any of the three types of ovarian tumors. SNP c.3944C>T showed significant differences between ovarian carcinoma and control samples with the minor T allele being significantly higher in controls compared to ovarian carcinomas. Interestingly, a new polymorphism c.-1184G>A was found only in tumor samples and further analyses should be performed in order to elucidate its potential role in ovarian tumors.

Cancer-Critical Genes II: Tumor Suppressor Genes
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.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

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,...
