The National Institutes of Health announces polyclonal antibodies against mouse cytochrome P450s CYP2J and CYP2C. Cytochrome P450s catalyze the metabolism of a wide range of exogenous compounds, including drugs, industrial chemicals, environmental pollutants, and carcinogens. The 2C family of cytochrome P450 metabolizes an extensive number of drugs which include tolbutamide, S-Warfarin, mephenytoin, diazepam and taxol. Many of the P450 enzymes are also active in the NADPH-dependent oxidation of arachidonic acid to various eicosanoids found in several species.

mEpoR-/- hEpoR+: The mouse Erythropoietin Receptor knockout that contains a human Erythropoietin Receptor transgene can be used to define the potency of recombinant erythropoietin preparations used to treat anemia associated with chronic kidney disease.

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.

Conditional knockout of Stat5a and Stat5b: Combined deletion of conserved Stat5a and Stat5b in mammary epithelium at different times during pregnancy reveal multiple distinct functions.

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

Sirt3 knockout: Sirt3 is a mitochondrial-localized tumor suppressor that maintains mitochondrial integrity and metabolism during stress.

Generation of floxed Sirtuin 6 for the construction of conditional knockout mice.

The Sirtuins (Sirt1-7), a family of seven proteins related to yeast Sir2, are histone deacetylases that regulate many critical biological processes including genomic stability, adaptation to calorie restriction and aging. Mice with a targeted disruption of Sirt6 had very low levels of blood glucose (and paradoxically, low insulin levels) and died shortly after weaning. Hypoglycemia, attributed to increased sensitivity to insulin, was the major cause for lethality.

Sirt1 knockout: Sirt1, a protein deacetylase, is a tumor suppressor that promotes genome stability and regulates proteins involved in energy metabolism.

Generation of floxed Sirtuin 1 Exon5-Exon6 for the construction of conditional knockout mice.

FGFR2 knockout is an embryonic lethal mutation and blocks limb bud initiation.
