Mouse Models

  • Pkd1 and Pkd2 Knock out alleles in a BL/6 background(1-3)
  • Pkd1v/v (knock in GPS cleavage mutant) in a BL/6 background(4)
  • Pkhd1△3-4 in a BL/6 background(5)
  • Pkhd1△67 in a BL/6 background (6)
  • Pkhd1HA endogenously tagged at the C-terminal region in a BL/6 background (6)
  • Pkd1 and Pkd2 conditional alleles in a BL/6 background (1-3)
  • Pkd1 and Pkd2 conditional alleles with the mTmG reporter in a BL/6 background (1-3, 7)
  • Pkd1 and Pkd2 conditional alleles with the ROSA reporter and tamoxifen Cre recombinase (1-3)
  • Pkd1 and Pkd2 conditional alleles with the Pax8-rtTA and TetO-Cre, which allows renal tubular inactivation (1-3, 8)
