The epigenetic modification during the induction of Foxp3 with sodium butyrate
Abstract
CD4 + CD25+ regulatory T (Treg) lymphocytes are critical for immune homeostasis. Foxp3 (Forkhead Box protein P3) is always considered as a marker of function and identities determination of Treg cells because of special occurring in Treg cell. People who lack Treg cells or have a low expression of Foxp3 gene will suffer fatal autoimmunity. Scientists are trying to use Treg cells as a treatment for autoimmune disease, such as systemic lupus erythematosus. Our objective was to induce Foxp3 + CD4+ T cells from naïve CD4 + T cells isolated from C57 mice spleen in vitro using stimuli that include the short chain fatty acid sodium butyrate. Furthermore, to explore the relationship between Foxp3+ T cells induction and epigenetic modification, by observing the changes of Foxp3, Ezh2 (Enhancer of Zeste Homolog 2) and phosphorylated Ezh2 in the induced Treg cells. The naïve CD4+ T cells were separated from C57 mice spleen by immunomagnetic separation. Anti-CD28, anti-CD3, IL-2, TGF-β1, and sodium butyrate were added with proper concentration to induce Foxp3 expression during 72 hours. Then, we observed the effect of GSK126 (Ezh2 inhibitor) on the induction within the same over 72 hours duration. Then, western blot and Q-PCR were used to ...Continue Reading

Cell Signaling & Cancer Epigenetics (Keystone)
Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. This feed covers the latest research on signaling and epigenetics in cell growth and cancer.
Autoimmune Diseases
Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
