Inhibition of macromolecular synthesis in L1210 mouse leukemia ascites cells by hycanthone. 1975

R G Wilson, and R H Bodner, and G E Macwhorter

Hycanthone inhibits macromolecular synthesis in L1210 cells. At the same concentrations of hycanthone, DNA synthesis is inhibited to a greater extent than the synthesis of RNA. There is an inhibition by the drug of the synthesis of ribosomal precursor RNA; the synthesis of other types of RNA including heterogeneous and small-molecular-weight, also appears to be inhibited. Maturation of 45-S RNA does not seem to be affected, and there is a partial reversal of inhibition of both DNA and RNA synthesis by washing the cells free of hycanthone.

D009363 Neoplasm Proteins Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.
