UTX LoxP Mouse

UTX-flox.  Conditional knockout mice for the histone demethylase UTX (Kdm6a) conditional knockout will help understand its role as a tumor suppressor.

Di- and tri-methylations on histone H3 lysine 27 (H3K27me2 and H3K27me3) are epigenetic marks for…

Tg(MMTV-Cre)#Mam Mouse

Cre-recombinase under the control of mouse mammary tumor virus long terminal repeat (MMTV) was expressed in the salivary gland and mammary epithelial cells of adult mice, and induced recombination in all tissues.

The Cre recombinase from bacteriophage…

Stat5a KO(Stat5a tm1Mam) Mouse

Stat 5a Knockout: Stat5a deficiency results in the loss of prolactin-dependent mammary gland development and lactogenesis.

Prolactin induces mammary gland development and lactogenesis.  Binding of Prolactin to its receptor leads to the phosphorylation…

Stat1LoxP (Stat1 tm1Mam) Mouse

Selective inactivation of Stat 1 in mammary cells indicates that its effect as a tumor suppressor in breast is direct.

STAT1 is considered a tumor suppressor, but it is not known if this effect occurs directly in mammary cells or secondarily by…

Sphk1 KO Mouse

A Sphingosine kinase 1 (Sphk1) knockout mouse.

Sphingosine kinase 1 and 2 are enzymes that produce sphingosine-1-phosphate (S1P), a potent bioactive compound that activates a family of G-protein coupled receptors known as S1P receptors.  Triggering…
