Pointed (Pnt) is a transcriptional activator that functions downstream of the highly conserved Receptor Tyrosine Kinase (RTK) signaling pathway. Pnt is an ETS family transcription factor and encodes for two proteins, PntP1 and PntP2. However, while PntP1 is constitutively active, PntP2 is only active after being phosphorylated by MAPK in the RTK pathway. As mutations in pnt perturb the development...
IL‐1β, a major cytokine of proinflammatory response, has been implicated in bone loss. However, its effects on mesenchymal progenitor cells‐associated bone regeneration remain elusive. Here, we investigated the role of microRNA for the regulation of osteogenesis by IL‐1β in human bone marrow‐derived mesenchymal stem cells (hBMMSC). Our data suggested Homo sapiens (hsa)‐miR‐496 is induced by IL‐1β...
Bone morphogenetic protein 2 (BMP2, HGNC:1069, GeneID: 650) is a classical morphogen; a molecule that acts at a distance and whose concentration influences cell proliferation, differentiation, and apoptosis. Key events requiring precise Bmp2 regulation include heart specification and morphogenesis and neural development. In mesenchymal cells, the concentration of BMP2 influences myogenesis, adipogenesis,...
Interferon Regulatory Factor 6 (IRF6) is a critical regulator of differentiation, proliferation, and migration of keratinocytes. Mutations in IRF6 cause two autosomal dominant disorders characterized by cleft lip with or without cleft palate. In addition, DNA variation in IRF6 confers significant risk for non‐syndromic cleft lip and palate. IRF6 is also implicated in adult onset development and disease...
Golgins are a family of coiled‐coil proteins located at the cytoplasmic surface of the Golgi apparatus and have been implicated in maintaining Golgi structural integrity through acting as tethering factors for retrograde vesicle transport. Whereas knockdown of several individual golgins in cultured cells caused Golgi fragmentation and disruption of vesicle trafficking, analysis of mutant mouse models...
