Type Coisogenic; Mutant Strain; Transgenic; Mating System +/+ sibling x Hemizygote (Female x Male) Species laboratory mouse Generation N?+N1F3 (24-APR-08) Donating Investigator Daniel Tenen, Beth Israel Deaconess Medical Center Description
Hemizygotes are viable, fertile, normal in size, and do not display any behavioral abnormalities. Transgene expression is directed by the tetracycline-responsive element (TRE; tetO). When hemizygotes are bred with another transgenic mouse expressing either reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA) under the regulation of tissue-specific promoters , BCR-ABL1 fusion protein expression can be regulated in the appropriate tissue of the bitransgenic offspring with the tetracycline analog, doxycycline.These mice originally were designed to be bred with transgenic mice harboring a Tal1-tTA transgene (see Stock No. 006209), creating double transgenic offspring as a model for studies of the Philadelphia chromosome and inducible chronic myeloid leukemia.
When bred to a strain expressing tTA in the epithelial cells of secretory organs and skin (see Stock No. 002618 - Tg(MMTVtTa)1Mam), this mutant mouse strain may be useful in studies of leukemia.
Development
A transgene was generated containing a human p210 BCR-ABL1 fusion protein cDNA sequence under transcriptional control of the tetracycline-responsive element (TRE; tetO) sequence fused to a minimal cytomegalovirus (hCMV) promoter. The transgene was injected into fertilized FVB/N eggs. Transgenic offspring (founder line 2) were maintained by breeding transgenic mice to either FVB/N inbred mice or wildtype siblings for many generations prior to arrival at The Jackson Laboratory.

| General Note | This record is also representative of lines 3 and 4 that were also generated; all of these lines exhibit a similar phenotype in combination with Tg(MMTVtTA)1Mam.Bitransgenic mice with this transgene in combination with Tg(MMTVtTA)1Mam, when tetracycline administration is stopped, are models for B cell acute lymphoblastic leukemia (ALL); line 2 exhibits the greatest leukemia susceptibility (Figure 1). (J:72377) | ||
| Molecular Note | The transgene contains a cDNA encoding the human p210 BCR-ABL1 fusion protein (B3A2 form; J:86227) under transcriptional control of the tetracycline-responsive element (tetO; also called TRE) fused to a minimal cytomegalovirus (CMV) promoter. In doubly transgenic mice expressing a tetracycline transactivator or reverse transactivator protein under control of a ubiquitous or tissue-specific promoter, expression of the BCL-ABL1 fusion gene can be controlled temporally by withdrawal or administration of a tetracycline analog.
