Abstract:
This study was directed to the role of p53 gene in the carcinogenesis of thyroid carcinomas and to the correlation between p53 gene and the clinicopathological characteristics of the cancer. Single-stranded conformation polymorphism of PCR was used in detecting p53 gene point mutations in exons 7, 8. The result showed that ten of thirty-one thyroid carcinomas had mutations in exons 7 and 8 (32.3%). The frequency of p53 gene mutations was significantly higher in relapse group than in no relapse group (P < 0.01). No statistically significant differences in p53 mutation were found relating to metastasis, histological type and differentiation (P > 0.05). These data suggest that the mutation of p53 gene may play an important role in thyroid carcinoma and the mutations of p53 gene be associated with the prognosis of thyroid carcinoma.

Abnormal Proliferation
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
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.
Such genes that act...
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...
