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.

FGFR3 knockout. Complete knockout of the FGFR3 gene, the gene in which missense mutants cause short statue achondroplasia, fails to restrain cartilage growth at the bone growth plate, allowing bones to elongate excessively but fail to ossify.

HSPA2 is a member of the HSP70 family of heat-shock proteins that serve as molecular chaperones. Researchers discovered that HSPA2 protein is expressed in spermatogenesis during the meiotic phase. Spermatogenic cells lacking the HSPA2 protein arrest in mid-meiosis and undergo apoptosis. HSPA2 is present in the synaptonemal complex of wild-type mice and the chromosomes fail to separate in HSPA2-deficient mice (previously known as Hsp70-2-/- mice), suggesting that HSPA2 is required for the chromosomal events of meiosis such as synapsis, crossing over, or recombination.

HSPA2 is a member of the HSP70 family of heat-shock proteins that serve as molecular chaperones. Hspa2-cre expression mimics the spermatogenic cell-specific expression of endogenous HSPA2 within the testis, being first observed in leptotene/zygotene spermatocytes. Expression of the transgene is also detected at restricted sites in the brain, as occurs for endogenous HSPA2.

This molecular probe may serve as a companion tool to identify and stratify patient populations based on the prevalence of the target A₃ adenosine receptors.

Small molecule drugs, A₃AR-selective agonists, are currently in advanced clinical trials for the treatment of hepatocellular carcinoma, autoimmune inflammatory diseases, such as rheumatoid arthritis, psoriasis, and dry eye disease, and other conditions.

The five Muscarinic Acetylcholine (ACh) receptors are G-protein coupled receptors (M1R-M5R). M3 muscarinic ACh receptors are present in the central nervous system and the periphery.

Atherosclerosis underlies most cases of cardiovascular disease (CVD), which is now the major cause of morbidity and mortality in developed countries. An inflammatory reaction is an essential component in the appearance and development of an atherosclerotic lesion. The inflammatory process is associated with the expression of adhesion molecules such as vascular cell adhesion molecule (VCAM) at the surface of endothelial cells. Antiatherogenic lipoprotein, high density lipoprotein (HDL), is known to down regulate the expression of VCAM.

Airway diseases, such as Asthma and Chronic Obstructive Pulmonary Disease (COPD), constitute a major health burden worldwide. It is estimated, for example, that nearly 15.0% of the adult population in the US are affected with such diseases, and the economic cost burden is over $23 billion annually. Unfortunately, the current options for treatment of such diseases are quite limited, consisting only of bronchodilators and inhaled steroids. The need for a novel and more effective class of therapeutics agents is imperative.

The transfusion of regulatory T cells (Tregs) has been used in the clinic to successfully prevent graft vs. host disease and is currently being evaluated in the treatment of other autoimmune diseases, such as organ graft rejection, type 1 diabetes and multiple sclerosis. Prior to transfusion, adoptive regulatory T cell transfer requires the expansion of regulatory T cells in culture; this results in a mixed population of regulatory T cells that limits the effectiveness of the transferred cells.
