Total RNA was isolated from tissues and embryonic gonads using
TRIzol (Thermo Fisher). cDNA was generated from total RNA using
Superscript III (Thermo Fisher) followed by PCR amplification using
Ex-Taq polymerase (Takara) and template cDNA.
For RT-qPCR, total RNA was isolated from WT (n = 3) and
Meiosin KO (n = 3) testes, and cDNA was generated as described previously (Ishiguro et al., 2020 (
link)).
Fbxo47 cDNA was quantified by ΔCT method using TB Green Premix Ex Taq II (Tli RNaseH Plus) and
Thermal cycler Dice (Takara), and normalized by
GAPDH expression level.
qPCR was performed in duplicates, and the average ddCt value was calculated for each cDNA sample. The expression level of
Fbxo47 was divided by that of
GAPDH to give the relative expression level of
Fbxo47 to
GAPDH. Relative expression level of
Fbxo47 to
GAPDH was normalized to 1 for a given P10 WT sample.
Sequences of primers used for RT-PCR were as follows:
GAPDH-F: 5’-TTCACCACCATGGAGAAGGC-3’
GAPDH-R: 5’-GGCATGGACTGTGGTCATGA-3’
Gapdh_F2: 5’-ACCACAGTCCATGCCATCAC-3’
Gapdh_R2: 5’-TCCACCACCCTGTTGCTGTA-3’
Gapdh_Ex6F: 5’-GGTTGTCTCCTGCGACTTCA-3’
Gapdh_mRNAR: 5’-GCCGTATTCATTGTCATACCAGG-3’
Fbxo47-F 1443F: 5’-GCATAGCAAATGCTTTTGCCTGTG-3’
Fbxo47-R 1605R: 5’-GAGATAGCGTTCATGGTCAGATAC-3’
