Background: Hepatocellular carcinoma is the most common primary malignant tumor of the liver. The effect of some genes especially those involved in cell cycle regulation have been shown in the development of this cancer in several studies but there are some controversies about them yet. Materials and methods: The paraffin-embedded tissue samples of 25 patients (18 males and 7 females) with hep...
متن کاملDominant transformation by mutated human ras genes in vitro requires more than 100 times higher expression than is observed in cancers.
The gene-mutation-cancer hypothesis holds that mutated cellular protooncogenes, such as point-mutated proto-ras, "play a dominant part in cancer," because they are sufficient to transform transfected mouse cell lines in vitro [Alberts, B., Bray, D., Lewis, J., Raff, M., Roberts, K. & Watson, J. D. (1994) Molecular Biology of the Cell (Garland, New York)]. However, in cells transformed in vitro ...
متن کاملRas Genes in Human Breast Cancer
The expression of ras mRNA levels in 27 human sporadic breast cancer specimens was examined, and compared to the corresponding adjacent normal tissue using the RT-PCR technique. Eighteen out of the 27 specimens (67%) exhibited twoto four-fold increased expression of ras mRNA levels, compared to corresponding normal tissue. The rates of augmented mRNA expression were similar among the three ras ...
متن کاملSos-mediated cross activation of wild-type Ras by oncogenic Ras is essential for tumorigenesis
Mammalian cells contain three closely related ras genes, H-ras, K-ras and N-ras. Although in a given tumour type, oncogenic mutations are selectively observed in only one of the ras genes, the acquisition of the transformed phenotype has been shown to require the contribution of the normal products of the other ras genes. Here we demonstrate that oncogenic K-Ras promotes the activation of wild-...
متن کاملIn TCR-Stimulated T-cells, N-ras Regulates Specific Genes and Signal Transduction Pathways
It has been recently shown that N-ras plays a preferential role in immune cell development and function; specifically: N-ras, but not H-ras or K-ras, could be activated at and signal from the Golgi membrane of immune cells following a low level T-cell receptor stimulus. The goal of our studies was to test the hypothesis that N-ras and H-ras played distinct roles in immune cells at the level of ...
