A dual role for ErbB2 signaling in cardiac trabeculation.
(Development, 2010-11)Cardiac trabeculation is a crucial morphogenetic process by which clusters of ventricular cardiomyocytes extrude and expand into the cardiac jelly to form sheet-like projections. Although it has been suggested that cardiac ... -
A miR-34a-Numb Feedforward Loop Triggered by Inflammation Regulates Asymmetric Stem Cell Division in Intestine and Colon Cancer.
(Cell Stem Cell, 2016-02-04)Emerging evidence suggests that microRNAs can initiate asymmetric division, but whether microRNA and protein cell fate determinants coordinate with each other remains unclear. Here, we show that miR-34a directly suppresses ... -
A novel, non-apoptotic role for Scythe/BAT3: a functional switch between the pro- and anti-proliferative roles of p21 during the cell cycle.
(2012)Scythe/BAT3 is a member of the BAG protein family whose role in apoptosis, a form of programmed cell death, has been extensively studied. However, since the developmental defects observed in Bat3‐null mouse embryos cannot ... -
A switch in the control of growth of the wing imaginal disks of Manduca sexta.
(PLoS One, 2010-05-19)BACKGROUND: Insulin and ecdysone are the key extrinsic regulators of growth for the wing imaginal disks of insects. In vitro tissue culture studies have shown that these two growth regulators act synergistically: either ... -
ACE-inhibition increases podocyte number in experimental glomerular disease independent of proliferation.
(Journal of the renin-angiotensin-aldosterone system : JRAAS, 2015-06)<h4>Objective</h4>The objective of this article is to test the effects of angiotensin-converting enzyme (ACE)-inhibition on glomerular epithelial cell number in an inducible experimental model of focal segmental ... -
An aberrant SREBP-dependent lipogenic program promotes metastatic prostate cancer.
(Nature genetics, 2018-02)Lipids, either endogenously synthesized or exogenous, have been linked to human cancer. Here we found that PML is frequently co-deleted with PTEN in metastatic human prostate cancer (CaP). We demonstrated that conditional ... -
Analysis of Epstein-Barr virus-regulated host gene expression changes through primary B-cell outgrowth reveals delayed kinetics of latent membrane protein 1-mediated NF-κB activation.
(Journal of virology, 2012-10)Epstein-Barr virus (EBV) is an oncogenic human herpesvirus that dramatically reorganizes host gene expression to immortalize primary B cells. In this study, we analyzed EBV-regulated host gene expression changes following ... -
Arterial pole progenitors interpret opposing FGF/BMP signals to proliferate or differentiate.
(Development, 2010-09)During heart development, a subpopulation of cells in the heart field maintains cardiac potential over several days of development and forms the myocardium and smooth muscle of the arterial pole. Using clonal and explant ... -
Beta-arrestins regulate atherosclerosis and neointimal hyperplasia by controlling smooth muscle cell proliferation and migration.
(Circ Res, 2008-07-03)Atherosclerosis and arterial injury-induced neointimal hyperplasia involve medial smooth muscle cell (SMC) proliferation and migration into the arterial intima. Because many 7-transmembrane and growth factor receptors promote ... -
c-Myc is required for maintenance of glioma cancer stem cells.
(PLoS One, 2008)BACKGROUND: Malignant gliomas rank among the most lethal cancers. Gliomas display a striking cellular heterogeneity with a hierarchy of differentiation states. Recent studies support the existence of cancer stem cells in ... -
Cancer-cell-derived GABA promotes β-catenin-mediated tumour growth and immunosuppression.
(Nature cell biology, 2022-02)Many cancers have an unusual dependence on glutamine. However, most previous studies have focused on the contribution of glutamine to metabolic building blocks and the energy supply. Here, we report that cancer cells with ... -
Cryopreserved Mesenchymal Stromal Cells Are Susceptible to T-Cell Mediated Apoptosis Which Is Partly Rescued by IFNγ Licensing.
(Stem cells (Dayton, Ohio), 2016-09)We have previously demonstrated that cryopreservation and thawing lead to altered Mesenchymal stromal cells (MSC) functionalities. Here, we further analyzed MSC's fitness post freeze-thaw. We have observed that thawed MSC ... -
Cryptococcal cell morphology affects host cell interactions and pathogenicity.
(PLoS Pathog, 2010-06-17)Cryptococcus neoformans is a common life-threatening human fungal pathogen. The size of cryptococcal cells is typically 5 to 10 microm. Cell enlargement was observed in vivo, producing cells up to 100 microm. These morphological ... -
CYLD inhibits melanoma growth and progression through suppression of the JNK/AP-1 and β1-integrin signaling pathways.
(J Invest Dermatol, 2013-01)The molecular mechanisms mediating cylindromatosis (CYLD) tumor suppressor function appear to be manifold. Here, we demonstrate that, in contrast to the increased levels of phosphorylated c-Jun NH(2)-terminal kinase (pJNK), ... -
Diet-induced obesity alters the differentiation potential of stem cells isolated from bone marrow, adipose tissue and infrapatellar fat pad: the effects of free fatty acids.
(Int J Obes (Lond), 2013-08)INTRODUCTION: Obesity is a major risk factor for several musculoskeletal conditions that are characterized by an imbalance of tissue remodeling. Adult stem cells are closely associated with the remodeling and potential repair ... -
Effect of microRNA modulation on bioartificial muscle function.
(Tissue Eng Part A, 2010-12)Cellular therapies have recently employed the use of small RNA molecules, particularly microRNAs (miRNAs), to regulate various cellular processes that may be altered in disease states. In this study, we examined the effect ... -
Enhanced osteogenic potential of mesenchymal stem cells from cortical bone: a comparative analysis.
(Stem cell research & therapy, 2015-10)<h4>Introduction</h4>Mesenchymal stem cells (MSCs) hold great promise for regenerative therapies in the musculoskeletal system. Although MSCs from bone marrow (BM-MSCs) and adipose tissue (AD-MSCs) have been extensively ... -
Experimental inhibition of porcupine-mediated Wnt O-acylation attenuates kidney fibrosis.
(Kidney Int, 2016-05)Activated Wnt signaling is critical in the pathogenesis of renal fibrosis, a final common pathway for most forms of chronic kidney disease. Therapeutic intervention by inhibition of individual Wnts or downstream Wnt/β-catenin ... -
G protein-coupled receptor kinase 3 modulates mesenchymal stem cell proliferation and differentiation through sphingosine-1-phosphate receptor regulation.
(Stem cell research & therapy, 2022-01-29)<h4>Background</h4>The bone marrow niche supports hematopoietic cell development through intimate contact with multipotent stromal mesenchymal stem cells; however, the intracellular signaling, function, and regulation of ... -
Identification of select glucocorticoids as Smoothened agonists: potential utility for regenerative medicine.
(Proc Natl Acad Sci U S A, 2010-05-18)Regenerative medicine holds the promise of replacing damaged tissues largely by stem cell activation. Hedgehog signaling through the plasma membrane receptor Smoothened (Smo) is an important process for regulating stem cell ...
