We report herein the synthesis and characterization of copper oxide quantum dots and their cytotoxic impact on mouse C2C12 cells. The utilized CuO quantum dots were prepared by the one-pot wet chemical method using copper acetate and hexamethylenetetramine as precursors. The physicochemical characterization of the synthesized CuO quantum dots was carried(More)
Animal cell culture is a highly complex process, in which cells are grown under specific conditions. The growth and development of these cells is a highly unnatural process in vitro condition. Cells are removed from animal tissues and artificially cultured in various culture vessels. Vitamins, minerals, and serum growth factors are supplied to maintain cell(More)
Zinc oxide (ZnO) nanostructures have been commonly studied for electronic purposes due to their unique piezoelectric and catalytic properties; however, recently, they have been also exploited for biomedical applications. The purpose of this study was to fabricate ZnO-doped poly(urethane) (PU) nanocomposite via one-step electrospinning technique. The(More)
The present study was carried out to understand the co-culture effect of C2C12 and 3T3-L1 preadipocyte cells on calpain, caspase, and heat shock protein (Hsp) systems. Calpains, caspases, and heat shock proteins play critical roles in the growth and development of mammalian cells. Cells were co-cultured using transwell inserts with a 0.4-μm porous membrane(More)
Calcium absorption is regulated by both active (transcellular) and passive (paracellular) pathways. Although each pathway has been studied, correlations between the two pathways have not been well elucidated. In previous investigations, the critical transcellular proteins, calbindin-D9k (CaBP-9k) and -D28k (CaBP-28k), were shown to affect other(More)
Lentinus (L.) edodes (shiitake mushroom) is used as a traditional medicine in Asia. One of the components of L. edodes, eritadenine (an adenosine analog alkaloid), has been shown to reduce cholesterol levels. The hypocholester-olemic action of eritadenine appears to be achieved through the modification of hepatic phospholipid metabolism. In the present(More)
The current study was undertaken to determine the effect of the troglitazone (TGZ) on the expression of peroxisome proliferator-activating receptor (PPARγ), CCAAT/enhancer-binding protein, fatty acid binding protein 4, calpain 1 (CAPN1), and lipid accumulation in the myotube of Hanwoo muscle satellite cells. The satellite cells were treated with 5, 10, and(More)
The current study was conducted to evaluate the functions of μ-calpain (CAPN1), calpastatin, HSPs (heat shock proteins), and caspases during myogenesis and cell death induced by sodium azide (NaN3) hypoxia. The cell samples were divided into three groups: satellite cells formed at confluent monolayer (stage 1), stage 1 cells fusion into myotubes on d eight(More)
Calpastatin participates in apoptotic cell death and cell signaling, but its role in skeletal myoblast development and molecular involvements in cell growth still remains unknown. The current study aimed to investigate the role of calpastatin on the expression patterns of calpains, caspases, and heat shock proteins (HSPs). In addition, the cell viability(More)
Recently, substantial interest has been generated in using electrospun biomimetic nanofibers of hybrids, particularly organic/inorganic, to engineer different tissues. The present work, for the first time, introduced a unique natural and synthetic hybrid micronanofiber wound dressing, composed of virgin olive oil/copper oxide nanocrystals and polyurethane(More)
