Comparative incorporation of uridine-3H into nucleolar RNA of mouse subcutaneous and skin tissues at early times after 20-methylcholanthrene administration.

A single s.c. injection of 20-methylcholanthrene (1 mg in 0.2 ml olive oil) is found to stimulate the relative uptake of uridine-3H by the skin and the s.c. tissue 17- and 3fold respectively, 24 h post-administration.
