Tissue distribution of the mRNA expression of GR1, GR2 and MR
Total RNA was extracted from the forebrain, midbrain, hypothalamus,
pituitary, gill, kidney and intestine of tilapia. The complementary
DNA (cDNA) strand was synthesized with 1 lg of
total RNA using SuperScript II with oligo(dT)1218 primers. Genespecific
primers were employed for the RT-PCR analysis (Table 1).
The glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene
was used as an internal control. The PCR conditions were as follows:
94 C for 1 min, 55 C for 1 min, and 72 C for 2 min for 30 cycles.
The PCR products were separated on a 1.5% agarose gel.
