Fig. 1. Agarose gel electrophoresis of RT-PCR products. (A) fRLX mRNA
expression on frog testis treated with T and T in combination with CPA at 2, 8
and 24 h. (B) fP1 expression on the same samples used as control.
Control, initial control frog testis. Lane C, control PCR without cDNA; M,
molecular mass marker VIX (Roche Diagnostic). (C) Relative density of the
fRLX and fP1 band measured with Gel Doc.

Fig. 2. (A) Northern blot analysis of total RNA extracted from frog testis
hybridized with the fRLX cDNA as probe. Each lane contained 20 µg
of total RNAs extracted from testis incubated with vehicle alone (Krebs),
testosterone (T) and T in combination with CPA. (B) The same filter was
hybridized with the fP1 cDNA probe as control. (C) Relative density
of the fRLX and fP1 band measured with Gel Doc.

Fig. 3. In vivo CPA treatment. (A) Levels of fRLX mRNA determined
by RT-PCR on initial control (lane 3), 15 days control (lane 4) and 15 days
CPA-treated (lane 5) frog testis. Lane 1: molecular mass marker VIX (Roche
Diagnostic); lane 2: control PCR. (B) fP1 mRNA levels used as
control. (C,D) In situ hybridization of fRLX antisense mRNA
on the control (C) and in the CPA-treated frog testis (D).
