Research Material DescriptionPrincipal Investigator
Therapeutic Polypeptides and Their Use (U.S. Patent Application Number 61/890,585)NIDDK investigators have developed a synthetic polypeptide with beneficial effects and prospective treatment of chronic kidney disease (CKD).  End stage renal disease (ESRD) is a major health and economic burden and requires transplantation or dialysis … (Summary)Peter Yuen, Ph.D.
Sphk1 KO MouseA 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 … (Summary)Richard L. Proia, Ph.D.
Stat1LoxP (Stat1 tm1Mam) MouseSelective 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 disrupting … (Summary)Lothar Hennighausen, Ph.D.
Stat5a KO(Stat5a tm1Mam) MouseStat 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 … (Summary)Lothar Hennighausen, Ph.D.
Stat5a LoxP/Stat5b LoxP (Stat5a/Stat5b tm2Mam) MouseConditional knockout of Stat5a and Stat5b: Combined deletion of conserved Stat5a and Stat5b in mammary epithelium at different times during pregnancy reveal multiple distinct functions.   The signal transducer and activator of transcription (STAT) … (Summary)Lothar Hennighausen, Ph.D.
Tg(Wap-cre)11738Mam MouseCre-recombinase under the control of the whey acidic acid protein was only detected in alveolar epithelial epithelial cells of mammary tissue during lactation, and transcription occurred at all stages of mammary development.   The Cre recombinase from … (Summary)Lothar Hennighausen, Ph.D.
Tg(MMTV-Cre)#Mam MouseCre-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 … (Summary)Lothar Hennighausen, Ph.D.
UTX LoxP MouseUTX-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 … (Summary)Kai Ge, Ph.D.
Small volume viscometerNIDDK scientists have developed a capillary-based device and system for measuring the rheological properties of solutions of synthetic and biological polymers. The device automatically serially dilutes and varies the flow rate of a sample, permitting … (Summary)Allen P. Minton, Ph.D.
Inducible podocyte-specific gene expression in transgenic miceThe podocyte plays a key role in glomerular function and glomerular disease. To facilitate studies of podocyte function, we have developed a transgenic mouse model with inducible expression in the podocyte. The tetracycline-inducible transgenic system … (Summary)Jeffrey B. Kopp, M.D.
DNA sequence acting as an insulator for the effects of cis-acting regulatory elementsA newly characterized chromatin insulator element isolated from the DNA of a higher eukaryotic organism and contained in vector constructs is described. The insulator element of the invention comprises a DNA sequence which contains a 5’ constitutive … (Summary)Gary Felsenfeld, Ph.D.
Gs Alpha LoxP (Gnas tm1Lsw) MouseGeneration of a floxed Gnsa gene for the G-protein Gsα for the construction of conditional knockout mice.   The heterotrimeric G protein Gsa couples many receptors to adenylyl cyclase and is essential for hormone-stimulated cAMP generation.  Previous … (Summary)Lee S. Weinstein, M.D.
Method for Spectrally Selective B1 Insensitive T2 Preparation Contrast Enhancement for High Field Magnetic Resonance ImagingA T2 preparation sequence uses a segmented BIR-4 adiabatic pulse with two substantially equal delays and is insensitive to B1 field variations and can simultaneously suppress fat signals with low specific absorption rate (SAR). An adiabatic reverse half … (Summary)Ronald Ouwerkerk, Ph.D.
Alb-tTA (Tg(Alb1-tTA)3123Lng) MouseTetracycline-responsive transcriptional activator driven by the liver-specific mouse albumin promoter (Alb-tTA)   The E. Coli tetracycline operon regulatory system was used to generate a liver-specific transcription activation system that was inhibited … (Summary)T. Jake Liang, M.D.
MUP-tTA MouseTetracycline-responsive transcriptional activator driven by the liver-specific mouse major urinary protein promoter (MUP-tTA)   The E. Coli tetracycline operon regulatory system was used to generate a liver-specific transcription activation system … (Summary)T. Jake Liang, M.D.
