The Emc3 conditional knockout allele (Emc3fl/+) was described previously [19 (link)]. BC-specific Emc3 knockout mice were generated by mating Emc3fl/+ mice to transgenic Cre line Pcp2-Cre [20 (link)]. The F1 progeny Emc3fl/+; Pcp2-Cre mice were crossed to generate Emc3fl/fl mice (Emc3fl/fl; Pcp2-Cre, named Emc3 cKO). Emc3fl/fl, Emc3fl/+ or Emc3fl/+; Pcp2-Cre mice were used as controls. To monitor the efficiency of Cre-mediated deletion of the floxed exon, a tdTomato reporter was used (Jackson Laboratory Cat# JAX:007914).
Tissues were harvested after animals were euthanized by CO2 exposure, which was confirmed by decapitation. No animals were excluded from this study. The number of mice used in each test was listed in
