Application

Dexamethasone has been used as a DMEM medium supplement utilized in osteogenesis. It has also been used as an alpha-MEM medium supplement to initiate adipogenic differentiation. Additionally, it has also been used to study apoptosis, cell signaling pathways and gene expression.

Biochem/physiol Actions

Dexamethasone is a glucocorticoid anti-inflammatory agent. It regulates T cell survival, growth, and differentiation. Additionally, dexamethasone inhibits the induction of nitric oxide synthase. It induces apoptosis by initiating the initial cleavage of DNA into high molecular weight fragments.
Glucocorticoid anti-inflammatory agent. Regulates T cell survival, growth, and differentiation. Inhibits the induction of nitric oxide synthase.

Apoptosis is a major form of cell death, characterized morphologically by chromatin condensation and biochemically by endonuclease cleavage of DNA into oligonucleosomal fragments. Recently, we reported that zinc arrested dexamethasone-induced apoptosis in thymocytes at an early stage, as characterized morphologically

Mesenchymal stem cells (MSCs) have been isolated based on the ability of adherence to plastic surfaces. The potential of these cells to differentiate along multiple lineages is the key to identifying stem cell populations in the absence of molecular markers.

Glucocorticoid resistance is a major driver of therapeutic failure in T cell acute lymphoblastic leukemia (T-ALL). Here, we identify the AKT1 kinase as a major negative regulator of the NR3C1 glucocorticoid receptor protein activity driving glucocorticoid resistance in T-ALL. Mechanistically

Glucocorticoids are known to induce osteocyte apoptosis, whereas mechanical loading has been shown to sustain osteocyte viability. Here we show that mechanical loading in the form of fluid-flow shear stress blocks dexamethasone-induced apoptosis of osteocyte-like cells (MLO-Y4). Prostaglandin E(2) (PGE(2)
