Antisense oligonucleotides targeted against protein kinase Cbeta and CbetaII block 1,25-(OH)2D3-induced differentiationR U Simpson
Department of Pharmacology, The University of Michigan, Ann Arbor, Michigan 48109 0632, USA
J Biol Chem 273:19587-91. 1998..D.) but had no effect on 1,25-(OH)2D3 inhibition of cellular proliferation. These results indicate that the effects of 1,25-(OH)2D3 on HL-60 cell differentiation and proliferation can be dissociated by blocking PKCbetaII expression...
Characterization of heart size and blood pressure in the vitamin D receptor knockout mouseRobert U Simpson
Department of Pharmacology, University of Michigan, School of Medicine, 1301 MSRB III, 1150 West Medical Center Drive, Ann Arbor, MI 48109 0632, USA
J Steroid Biochem Mol Biol 103:521-4. 2007..Data presented here reveal that ablation of the VDR signaling system results in profound changes in heart structure. We propose that calcitriol acts directly on the heart as a tranquilizer by blunting cardiomyocyte hypertrophy...
Characterization of vitamin D receptor (VDR) in lung adenocarcinomaSo Hee Kim
Division of Medical Oncology, Department of Internal Medicine, University of Michigan, Ann Arbor, USA
Lung Cancer 77:265-71. 2012..In the present study, we characterized VDR expression in lung adenocarcinoma (AC)...
1,25-Dihydroxyvitamin-D3 treatment reduces cardiac hypertrophy and left ventricular diameter in spontaneously hypertensive heart failure-prone (cp/+) rats independent of changes in serum leptinPeter Mancuso
Department of Environmental Health Sciences, University of Michigan, Ann Arbor, Michigan 48109, USA
J Cardiovasc Pharmacol 51:559-64. 2008..These studies suggest that 1,25(OH)2D3 treatment may prevent the development of cardiac hypertrophy, an important contributing factor in the progression of congestive heart failure...
Functional vitamin D receptor (VDR) in the t-tubules of cardiac myocytes: VDR knockout cardiomyocyte contractilityDaniel X Tishkoff
Department of Pharmacology, University of Michigan Medical School, Ann Arbor, MI 48109, USA
Endocrinology 149:558-64. 2008..This novel discovery is fundamentally important in understanding 1,25(OH)(2)D(3) signal transduction in heart cells and provides further evidence that the VDR plays a role in heart structure and function...
Interaction between vitamin D receptor with caveolin-3 and regulation by 1,25-dihydroxyvitamin D3 in adult rat cardiomyocytesGuisheng Zhao
Department of Pharmacology, University of Michigan, School of Medicine, Ann Arbor, MI 48109, USA
J Steroid Biochem Mol Biol 121:159-63. 2010....
Membrane localization, Caveolin-3 association and rapid actions of vitamin D receptor in cardiac myocytesGuisheng Zhao
Department of Pharmacology, University of Michigan, School of Medicine, Ann Arbor, MI 48109, USA
Steroids 75:555-9. 2010....
1,25(OH)2-vitamin D3 actions on cell proliferation, size, gene expression, and receptor localization, in the HL-1 cardiac myocyteKarl A Nibbelink
Department of Pharmacology, University of Michigan School of Medicine, 1301 MSRB III, 1150 West Medical Center Drive, Ann Arbor, MI 48109 0632, USA
J Steroid Biochem Mol Biol 103:533-7. 2007..1,25D treatment also increased expression and nuclear localization of the VDR in these cardiac myocytes. Thus 1,25D is an important hormone involved in modulating and maintaining heart cell structure and function...
CYP24A1 is an independent prognostic marker of survival in patients with lung adenocarcinomaGuoan Chen
Section of Thoracic Surgery, Department of Surgery, Comprehensive Cancer Center, University of Michigan, Ann Arbor, Michigan 48109, USA
Clin Cancer Res 17:817-26. 2011..The purpose of our study was to assess CYP24A1 as a prognostic marker and to study its relevance to antiproliferative activity of 1,25-D(3) in lung AC cells...
Heart extracellular matrix gene expression profile in the vitamin D receptor knockout miceAyesha Rahman
Department of Pharmacology, University of Michigan Medical School, 1301 MSRB III, 1150 West Medical Center Drive, Ann Arbor, MI 48109 0632, USA
J Steroid Biochem Mol Biol 103:416-9. 2007..This data supports a role for 1,25D in heart ECM metabolism and suggests that MMPs and TIMPs expression may be modulated by vitamin D...
CARD-024, a vitamin D analog, attenuates the pro-fibrotic response to substrate stiffness in colonic myofibroblastsLaura A Johnson
University of Michigan, Department of Internal Medicine, Ann Arbor, MI 48109 0682, United States
Exp Mol Pathol 93:91-8. 2012..In summary, CARD-024 attenuated the pro-fibrotic response of colonic myofibroblasts to high matrix stiffness, suggesting that vitamin D analogs such as CARD-024 may ameliorate intestinal fibrosis...
Calcitriol modulation of cardiac contractile performance via protein kinase CJohn J Green
Department of Surgery, Cardiac Surgery Section, Ann Arbor, MI 48109, USA
J Mol Cell Cardiol 41:350-9. 2006..Phosphorylation of key Ca(2+) regulatory proteins by this kinase contributes to the enhanced relaxation observed in response to acute, but not chronic calcitriol...
The vitamin D/CYP24A1 story in cancerAmanda N King
Department of Medicine, University of Michigan, 1500 East Medical Center Drive, Ann Arbor, MI 48109, USA
Anticancer Agents Med Chem 10:213-24. 2010..The following review summarizes the available literature on CYP24A1 as it relates to 1,25(OH)(2)D(3) in cancer and outlines potential ways to inhibit CYP24A1 in an effort to improve the efficacy of exogenous 1,25(OH)(2)D(3)...
