The zinc finger protein ZFP36L2 has been shown by the inventors to play an essential role in hematopoiesis, a process that is dysregulated in hematological cancers, anemia, and other conditions. Thus, ZFP36L2 has promise for use in a diagnostic test to detect abnormal hematopoiesis, or as a target for the development of therapeutics to treat abnormal hematopoiesis.

This invention is a novel method and apparatus for greatly improving and sustaining spontaneous breathing in patients with severe respiratory failure. Continuous positive airway pressure (CPAP) is widely used in the treatment of patients with mild respiratory failure.

Recently-developed protein tags enable the specific covalent attachment of synthetic ligands, incorporating fluorophores or other substituted groups, to fusion proteins containing these tags. For example, SNAP and CLIP tags bind O⁶-benzylguanine-containing and O²-benzylcytosine containing ligands respectively, which can be derivatized with a wide variety of labels, including fluorescent dyes, affinity probes, and cross-linkers.

This technology is directed to the discovery of specific microRNAs that target and downregulate enzymes within the cholesterol biosynthetic pathway and is currently being tested in vivo.

Smad4 knockout: Smad4 is essential for epiblast proliferation, egg cylinder formation and mesoderm induction in early embryogenesis.

FGFR4 knockout: Lung alveoli fail to develop normally in double mutant with FGFR4 and FGFR3 knockouts.

Selective inactivation of Stat1 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 interferon signaling through the JAK/STAT1 pathway to induce immune responses. ERBB2/neu-induced breast cancer appeared sooner in mice lacking STAT1 only in mammary cells than in wild-type mice, indicating that STAT1 tumor suppression was intrinsic to mammary cells and not secondary to an induced immune response.

Cre-recombinase under the control of the whey acidic acid protein was only detected in alveolar epithelial cells of mammary tissue during lactation, and transcription occurred at all stages of mammary development.

Floxed Bcl-x: Conditional knockout of pro-survival Bcl-x in primordial germ cells was used to study the balance between pro-apoptotic Bax during embryogenesis.

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