RESEARCH DESIGN AND METHODS—Changes in islet protein levels of cyclins and of two critical cell cycle regulators cyclin kinase inhibitor p27 and S-phase kinase–associated protein 2 (Skp2) were assessed in mice treated with exendin-4 and in a mouse model with specific upregulation of nuclear cAMP signaling exhibiting increased -cell proliferation (CBP-S436A(More)
OBJECTIVE Beta-cell proliferation is an important mechanism underlying beta-cell mass adaptation to metabolic demands. We have examined effects, in particular those mediated through intracellular cAMP signaling, of the incretin hormone analog exendin-4 on cell cycle regulation in beta-cells. RESEARCH DESIGN AND METHODS Changes in islet protein levels of(More)
Pneumonia is a clinical diagnosis often treated empirically and successfully on an outpatient basis. When a patient fails to improve, the clinician is left to revisit the differential of pathogens and reconsider the host. Admission, imaging, and invasive and noninvasive testing are part of the toolkit for the severe or atypical case of pneumonia. For(More)
