OBJECTIVE
P-glycoprotein (Pgp) expression in neoplastic cells is known to reduce cell sensitivity to several cytotoxic Pgp substrates. A member of the ABC transporter family, Pgp, represents the most frequently described membrane efflux pump and its expression in neoplastic cells is responsible for
OBJECTIVE
To compare the difference of protein expression in the supernatant of heat injured keratinocytes (KC) and normal KC.
METHODS
A model of heat injured KC was produced in vitro. The supernatant of normal KC and heat injured KC was collected after culture for 12 hours, and was ultrafiltered
Mast cells (MCs) are long-lived resident cells known for their substantial role in antigen-induced anaphylaxis and other immunoglobulin E-mediated allergic reactions as well as tumor promotion. MCs' activation results in the release of pro-inflammatory factors such as histamine, tryptase, tumor
Legionella pneumophila, the causal agent of Legionnaires' disease, is an intracellular parasite and invades and proliferates within different eukaryotic cells, including human alveolar macrophages. After several 100-fold multiplication within host cells, the pathogens are released for new invasion
Hyaluronan (HA) is one of the most prevalent glycosaminoglycans of the vascular extracellular matrix (ECM). Abnormal HA accumulation within blood vessel walls is associated with tissue inflammation and is prominent in most vascular pathological conditions such as atherosclerosis and restenosis.
BACKGROUND
The aim of this study was an in vitro investigation of the effect of high glucose concentration on adipogenesis, as prolonged hyperglycemia alters adipocyte differentiation.
METHODS
3T3-L1 preadipocytes differentiated in the presence of varying concentrations of glucose (25, 45, 65, 85,
In animals, the Sep15 protein participates in disease resistance, growth, and development, but the function of its plant homologues remains unclear. Here, the function of maize Sep15 was analysed by characterization of two independent Sep15-like loss-of-function mutants. In the absence of
Glial cells have various important roles in regulation of brain functions. For such events, extracellular nucleotides/P2 receptors have central roles. Although there have been huge amount of literature about activation of P2 receptors and glial functions, little is known about what happens in glia
Our previous study found that glucosylceramide, a type of sphingolipids, was associated with liver inflammation and fibrosis. Glucosylceramide is generated by glucosylceramide synthase (GCS), which is encoded by the UDP‑glucose ceramide glucosyltransferase (UGCG) gene. GCS is a key enzyme to
