ABSTRACT
In mammals,there are two RNA-binding proteins,Musashi (Msi)1 and Msi2,constituting the Msi family.Msi2 is mainly distributed among neural,hematopoietic,gastrointestinal,pancreatic and epithelial stein cells.It is of great importance to maintain the balance between proliferation and differentiation of stem cells and regulate their growth and development.The changed expression of this protein will induce genesis and progression of malignant tumor through many kinds of signal pathways.Thus,Msi2 is trusted to provide a predictive mark and a therapeutic target for related tumors.
ABSTRACT
Isocitrate dehydrogenase 1 (IDH1), a key rate-limiting enzyme in tricarboxylic acid cycle,is found within the cytoplasm and peroxisomes.In recent years, IDH1 mutation is discovered in most gliomaand its large scale metabolites, 2-hydroxyglutarate, may be involved in tumor as potential carcinogens, and isshown to be closely related to better patients' survival as well.IDH1 mutation is anticipated to be a novel genet-ic biomarker which will guide the treatments of clinical glioma.
