  • Title: Alteration of glyceraldehyde-3-phosphate dehydrogenase activity and messenger RNA content by androgen in human prostate carcinoma cells.
    Author: Ripple MO, Wilding G.
    Journal: Cancer Res; 1995 Oct 01; 55(19):4234-6. PubMed ID: 7671226.
    Abstract:
    Glyceraldehyde-3-phosphate dehydrogenase (GAPDH, EC 1.2.1.12) activity and mRNA content is altered in the androgen-responsive human prostate carcinoma cell line LNCaP after exposure to the synthetic androgen R1881. Elevation in GAPDH activity is noted as early as 24 h after treatment with 1 nM R1881 and lasts at least 96 h. R1881 has no effect on the activity of GAPDH in androgen-independent DU145 cells. LNCaP GAPDH mRNA content is lowered by treatment with 1 nM R1881; the magnitude of reduction appears to depend on the length of exposure. The results present at least one means by which androgen-responsive tissues may develop alterations in GAPDH mRNA or activity, as is found in certain tumor tissues.
