Disruption of Vitamin D and Calcium Signaling in Keratinocytes Predisposes to Skin Cancer. [PDF]
, 2016 1,25 dihydroxyvitamin D (1,25(OH)2D), the active metabolite of vitamin D, and calcium regulate epidermal differentiation. 1,25(OH)2D exerts its effects through the vitamin D receptor (VDR), a transcription factor in the nuclear hormone receptor family ...

Dynamic Compression Improves Chondrogenesis in the Tissue Engineered Model of Cartilage
Biotechnology and Bioengineering, EarlyView.ABSTRACT Hyaline cartilage is a dense avascular tissue with low regenerative potential, present at the ends of the diarthrodial joints and in the cartilage growth plate. Skeletal diseases often result from extracellular changes in this tissue; however, studies of these are hindered by the tissue complexity, the difficulty in obtaining human material ...

A tale of three hedgehogs [PDF]
arXiv, 2017 In this work we study three topologies defined over the same set: the hedgehog. As the name suggests, the hedgehog can be described as a set of spines identified at a single point. Among others, we give a proof of the Kowalsky hedgehog theorem, which asserts that every metrizable space is embeddable into a countable cartesian power of the metric ...

Biophysical regulation of stem cell behavior within the niche. [PDF]
, 2012 Stem cells reside within most tissues throughout the lifetimes of mammalian organisms. To maintain their capacities for division and differentiation and thereby build, maintain, and regenerate organ structure and function, these cells require extensive ...

Phosphorylation at the Helm: Kinase‐Mediated Regulation of Primary Cilia Assembly and Disassembly
Cytoskeleton, EarlyView.ABSTRACT The primary cilium serves as an antenna of most vertebrate cells and is important for conveying cues from several signaling pathways into appropriate cellular responses during development and homeostasis. Cilia assembly and disassembly processes are thought to be strictly controlled; however, the precise nature of molecular events underlying ...

Cell Death and Disease, 2017 mTORC2 is aberrantly activated in cancer and therefore is considered to be an important therapeutic target. The hedgehog pathway, which is also often hyperactivated, regulates transcription of several genes associated with angiogenesis, metastasis ...

Stability of the melting hedgehog in the Landau-de Gennes theory of nematic liquid crystals [PDF]
, 2014 We investigate stability properties of the radially symmetric solution corresponding to the vortex defect (so called "melting hedgehog") in the framework of the Landau - de Gennes model of nematic liquid crystals. We prove local stability of the melting hedgehog under arbitrary $Q$-tensor valued perturbations in the temperature regime near the critical

Principles Of Differentiation And Morphogenesis [PDF]
, 2016 Developmental biology is the science connecting genetics with anatomy, making sense out of both. The body builds itself from the instructions of the inherited DNA and the cytoplasmic system that interprets the DNA into genes and creates intracellular and
