Tissue-specific distributions were carried out in a Light-
Cycler Real-time PCR detection system (Roche, USA).
For this purpose, the aforementioned tissues were taken
from three fish (n ¼3 biological replicates) and pooled.
First strand cDNA was synthesized from DNAseI treated
RNA (5 µg) using Revert Aid reverse transcriptase First
Strand cDNA Synthesis kit (Thermo Scientific, USA) as
per the manufacturer’s instructions. The 25-µL reaction
mix volume was prepared containing 12.5 µl of Maxima
SYBR Green qPCR master mix (Thermo Scientific,
USA), 0.5 µL of (10 pM) each gene-specific primer,
and 2 µL (20 ng) of cDNA. The default thermal profile
was used for PCR amplification and it consisted of an
initial denaturation at 95°C-10 min, followed by
40 cycles of denaturation at 95°C/15 sec and annealing
and extension at 60°C/1 min. Among three
