| Abstract: | Comparative study of concentrations of growing hexokinase subunits polypeptide chains in the polyribosomes from normal and tumour human stomach tissue is studied using specific antiserum to hexokinase isoenzyme from human stomach tumour tissue. It is shown by two different methods (chromatography on Sepharose 46 and sucrose concentration gradient analysis) that the content of hexokinase polypeptides in stomach tumour is several times higher than in homologous normal tissue. The acta obtained show that the high activity of hexokinase in tumour tissues is due to the increased synthesis rate of the enzyme. |
