Age-dependent expression of Utp14a and of different Utp14b transcript variants in wild-type mouse testes and expression in adult, germ-cell deficient W/Wv mutants. (A) Comparison of Utp14b variant 1 expression with that of variants 2+3 and 2+4. (B) Comparison of total Utp14b with Utp14a expression. Expression levels were first normalized to ribosomal protein Rps2 mRNA levels, and then the values for the adult wild-type testes were set at 1.0. Zero’s in place of bars, indicate that no transcript-specific RT-PCR product was produced.
