alphaA-Crystallin (alphaA) is a member of the small heat shock protein (sHSP) family and has the ability to prevent denatured proteins from aggregating in vitro. Lens epithelial cells express relatively low levels of alphaA, but in differentiated fiber cells, alphaA is the most abundant soluble protein. The lenses of alphaA-knock-out mice develop opacities(More)
alphaB-crystallin is a member of the small heat shock protein family and can act as a molecular chaperone preventing the in vitro aggregation of other proteins denatured by heat or other stress conditions. Expression of alphaB-crystallin increases in cells exposed to stress and enhanced in tumors of neuroectodermal origin and in many neurodegenerative(More)
alphaA- and alphaB-crystallins are molecular chaperones expressed at low levels in lens epithelial cells, and their expression increases dramatically during differentiation to lens fibers. However, the functions of alphaA- and alphaB-crystallins in lens epithelial cells have not been studied in detail. In this study, the relative ability of alphaA- and(More)
Mature adipocytes can revert to a more primitive phenotype and gain cell proliferative ability under the condition of ceiling method, named dedifferentiated fat cells (DFAT cells). These cells exhibit multilineage potential as adipose tissue-derived stromal cells (ADSCs). However, the stem molecular signature of DFAT cells and the difference distinct from(More)
PURPOSE Ultraviolet-B radiation (290-320 nm) produces cataracts in animals and has been associated with human cataract formation in several epidemiological studies. UVB radiation decreases the long-term cell survival and changes the pattern of protein synthesis in cultured lens epithelial cells. However, the relationship between DNA photoproduct formation(More)
PURPOSE Peptide growth factors including hepatocyte growth factor (HGF), platelet-derived growth factor (PDGF), and epidermal growth factor (EGF) are mitogens for many cell types and may act as regulators of lens epithelial cell growth and differentiation. The present study was undertaken to investigate the expression of growth factor receptors and(More)
Recent researches indicate that PGRN is closely related to diabetes and is regarded as a novel adipokine associated with obesity development, affecting adipocyte biology. In the present study, we investigated the effects and mechanisms of PGRN on porcine preadipocytes differentiation. Porcine preadipocytes were induced to differentiation with the addition(More)
Brown adipose tissue is important for maintaining energy homeostasis and adaptive thermogenesis in rodents and humans. As disorders arising from dysregulated energy metabolism, such as obesity and metabolic diseases, have increased, so has interest in the molecular mechanisms of adipocyte biology. Using a functional screen, we identified cyclin C (CycC), a(More)
Ceiling culture is an inverted and closed cell culture system which represents a novel method for exploring adipocyte characteristics and function. Although the role of ceiling culture in mature adipocyte dedifferentiation has been extensively studied, its potential effects on preadipocyte differentiation remain unclear. In this study, we established a(More)
