Hai Wu et al.
Genome biology, 15(3), R52-R52 (2014-03-25)
Osteogenesis is a highly regulated developmental process and continues during the turnover and repair of mature bone. Runx2, the master regulator of osteoblastogenesis, directs a transcriptional program essential for bone formation through genetic and epigenetic mechanisms. While individual Runx2 gene
Xiaoquan Zhu et al.
PLoS genetics, 10(10), e1004589-e1004589 (2014-10-24)
Distal arthrogryposis type 2B (DA2B) is an important genetic disorder in humans. However, the mechanisms governing this disease are not clearly understood. In this study, we generated knock-in mice carrying a DA2B mutation (K175del) in troponin I type 2 (skeletal
Vance Holt et al.
PloS one, 9(10), e108920-e108920 (2014-10-11)
Increased marrow medullary adipogenesis and an associated decrease in bone mineral density, usually observed in elderly individuals, is a common characteristic in senile osteoporosis. In this study we investigated whether cells of the medullary adipocyte lineage have the potential to
Yu Fei Lee et al.
PloS one, 9(9), e106661-e106661 (2014-09-05)
The orchestration of histone modifiers is required to establish the epigenomic status that regulates gene expression during development. Whsc1 (Wolf-Hirschhorn Syndrome candidate 1), a histone H3 lysine 36 (H3K36) trimethyltransferase, is one of the major genes associated with Wolf-Hirshhorn syndrome
Jie Chen et al.
Journal of cellular physiology, 229(11), 1647-1659 (2014-03-13)
Hertwig's epithelial root sheath (HERS) cells participate in cementum formation through epithelial-mesenchymal transition (EMT). Previous studies have shown that transforming growth factor beta 1 (TGF-β1) and fibroblast growth factor 2 (FGF2) are involved in inducing EMT. However, their involvement in
Xi-Wu Zhang et al.
The Journal of thoracic and cardiovascular surgery, 148(4), 1700-1708 (2014-04-08)
Valve calcification involves transdifferentiation of valve interstitial cells (VICs) into osteoblasts. Twist-related protein 1 (TWIST1) has been established as a negative regulator of osteoblast differentiation in both mouse and human mesenchymal stem cells, but its function in human aortic VICs
Jonathan R Peterson et al.
Science translational medicine, 6(255), 255ra132-255ra132 (2014-09-26)
Heterotopic ossification (HO) is the pathologic development of ectopic bone in soft tissues because of a local or systemic inflammatory insult, such as burn injury or trauma. In HO, mesenchymal stem cells (MSCs) are inappropriately activated to undergo osteogenic differentiation.
