Key Enzymes in Pyrimidine Synthesis, CAD and CPS1, Predict Prognosis in Hepatocellular Carcinoma

2021

Simple Summary Individual patients with liver cancer have a highly variable clinical course. Hence, there is an urgent need to identify new prognostic markers to determine prognosis and select specific therapies. Expression of two key enzymes in pyrimidine synthesis was analyzed in a large, well-characterized cohort of patients with liver cancer. Dysregulated expression of these enzymes was associated with shorter survival of the patients. A combined score of both markers was found to be a statistically independent prognostic marker. Abstract Patients with hepatocellular carcinoma (HCC) have a highly variable clinical course. Therefore, there is an urgent need to identify new prognostic mar…

Gene amplification in fibroblasts from ataxia telangiectasia (AT) patients and in X-ray hypersensitive AT-like Chinese hamster mutants.

2001

In search of functions involved in the regulation of gene amplification, and given the relevance of chromosome breakage in initiating the process, we analyzed the gene amplification ability of cells hypersensitive to inducers of DNA double-strand breaks and defective in cell cycle control: two human fibroblast strains derived from patients affected by ataxia telangiectasia (AT) and two hamster mutant cell lines belonging to complementation group XRCC8 of the rodent X-ray-sensitive mutants. These mutants are considered hamster models of AT cells. To measure gene amplification, the frequency and the rate of occurrence of N-(phosphonacetyl)-L-aspartate resistant cells were determined. In both …
