Mastl E166D knockin allele carrying the mutation found in thrombocytopenia patients.
Mastl E166D express normal levels of the mutant Mastl protein. These mice develop mild thrombocytopenia due to defects in platelet activation and alterations in the signaling pathways controlling actin dynamics.

Mastl alleles expressing a truncated form of Mastl.
Mastl alleles carrying specific insertion or deletions in the linker region and expressing short forms of the kinase. These alleles were generated using direct injection of CRISPR/Cas9 reagents in mouse embryos.

Knock-in of miR-203, inducible by DOXYCYCLINE treatment, through the Rosa 26_rtTA allele. Reverse tetracycline transactivator (rtTA)/tetracycline-responsive element (tet-O)-driven transgenes. To ensure reliable rtTA expression in a broad range of cell types, the rtTA transgene has been targeted into the ROSA26 locus. Transgen PyMT, constitutively active (not inducible), under the promoter of MMTV, only expressed in breast. Tumoral invasive lessions are observed in breast at 15 -16 weeks of age. Long latency model of breast cancer

Knock-out of miR-203 and Knock-in for OSKM (Oct4-Sox2-Klf4-Myc). The OSKM inducible strain was kindly provided by Manuel Serrano´s lab in 2014. We crossed the OSKM strain with our BED strain, knock out for miR-203. OSKM transgen is inducible by DOXYCYCLINE treatment, using Rosa 26_rtTA allele. Reverse tetracycline transactivator (rtTA)/tetracycline-responsive element (tet-O)-driven transgenes. To ensure reliable rtTA expression in a broad range of cell types, the rtTA transgene has been targeted into the ROSA26 locus.
