MOs: 0.3 mM of a combination of for mif, mif-like MO1, and mif-like MO2 was used. Mif MO is complimentary to the start codon of zebrafish mif mRNA: 5′-acatcggcatgactgcgacagagat-3′. Two MOs were used for mif-like. mif-like MO1 is complimentary to the translational start site: 5′-GTTTCTATATTTATGAACGGCATGA-3′, while mif-like MO2 derived from AS sequence at the intron1/exon 2 boundary: 5′-GATTCATCCTCTGAAGACGTAAGCC-3′. Control MO was the scrambled nucleotide sequence from Gene Tools: 5′-CCTCTTACCTCAGTTACAATTTATA- 3′.
