Description:
This is the wild type littermate of the Tti2 knockout rats. The knockout rats were generated by microinjecting fertilized ova of SHR/OlaIpcv rats with the ZFN (Zinc Finger Nuclease) construct from Sigma-Aldrich. The construct was designed to target the first exon using the following sequence of ZFN binding (capital letters) and cutting site (small letters): TCTGACCCGGATCCAAGCaccaagGGTGGGTGGCAGGGC. DNA samples isolated from 452 rats born after microinjection with ZFN construct were amplified using primers flanking the target sequence: ZFN F: 5'-TACACTGTGATTGGCTGGGA-3' and ZFN R: 5'-GGCGCAGTGGAGTGATC-3'. SHR-Tti2+/- with an 8 bp deletion (NM_001013883.1(Tti2):c.243_250delCGAGATCC; on the protein level: NP_001013905.1:p.Glu82Glyfs) has been selected for further analyses. The heterozygous founder was crossed with SHR and F1 rats were intercrossed. SHR-Tti2+/- heterozygotes were selected for breeding and this wild type littermates were used as controls.
Systems genetics in the rat HXB/BXH family identifies Tti2 as a pleiotropic quantitative trait gene for adult hippocampal neurogenesis and serum glucose.
