| Derivation: | Mice homozygous null for the caveolin-1 gene, Cav-1 (-/-), and their wild-type littermates, Cav-1 (+/+), were generated by targeted disruption of the caveolin-1 gene. A construct was introduced into WW6 embryonic stem (ES) cells by electroporation to disrupt the Cav-1 locus. Mouse embryonic fibroblasts (MEFs) were obtained from day 13.5 littermate mouse embryos and immortalized using the 3T3 protocol. Ref ![]() Razani B, et al. Caveolin-1 null mice are viable but show evidence of hyperproliferative and vascular abnormalities. J. Biol. Chem. 276: 38121-38138, 2001. PubMed: 11457855xa0 |
| Comments: | The 3T3 MEFs KO cell line (ATCC CRL-2753) is homozygous for a disruption of the caveolin-1 gene Cav-1 (-/-) while the 3T3 MEFs WT cell line (TS165974) is Cav-1 (+/+). Analysis of cultured fibroblasts from Cav-1 null embryos reveals a loss of caveolin-2 protein expression; defects in the endocytosis of a known caveolar ligand, (fluorescein isothiocyanate-albumin); and a hyperproliferative phenotype. These phenotypic changes are reversed by recombinant expression of the caveolin-1 cDNA. Ref A culture deposited with the ATCC in September of 2002 was found to be contaminated with mycoplasma. Progeny were cured by a 21-day treatment with BM Cyclin. The cells were assayed for mycoplasma, by the Hoechst stain, PCR and the standard culture test, after a six-week period following treatment. All tests were negative. Analysis of cultured fibroblasts from Cav-1 null embryos reveals a loss of caveolin-2 protein expression; defects in the endocytosis of a known caveolar ligand, (fluorescein isothiocyanate-albumin); and a hyperproliferative phenotype.
