Rlsson and Nilsson, 2014; Schultze et al., 2012; Thompson et al., 2015), that are also the central regulators EMT phenotype (Elsum et al., 2013; Larue and Bellacosa, 2005; Mulholland et al., 2012). We further demonstrated that ARS4 inactivated PI3K/AKT and MAPK pathway with respect to down-regulation of phosphorylated AKT, mTOR, and ERK. Melphalan is usually a clinical-used alkylating antitumor agent and is often the drug of selection in the remedy of ovarian, melanoma, and breast cancer. Melphalan, shows a diversity of toxic side effects especially when employed at a higher dose (Casanova et al., 2012). Presently, we proved that ARS4, an artemisinin-melphalan conjugate, markedly inhibited local growth and intraperitoneal dissemination and metastasis of xenografts of ovarian cancer cells with no observable toxic effects, and showed enhanced water-solubility and improved potency and safety related to DHA and melphalan. In summary, series of hybrid ARS derivatives conjugated with clinically employed chemotherapeutic agents were developed and synthesized based on the hybrid approach. On the basis of their efficacy in cell cultures and in mice, these ARS-drug hybrids, especially ARS4, are promising as lead compounds for improvement of chemotherapeutic agents for the therapy of ovarian cancer.

Oligodendrocyte progenitor cells (OPC) are broadly recognized by the expression of platelet-derived growth aspect a receptor (PDGFaR) and chondroitin sulfate proteoglycan (Cspg4 or NG2).1,two Differentiation into mature oligodendrocytes is regulated by the successive expression of transcription aspects (not too long ago reviewed by Kspert et al.3). Briefly, OPC are specified u by the combined expression of Ascl1, Dlx1/Dlx2 and Olig1/Olig2, then Sox10 and Nkx2.two.4-8 Upon differentiation, cells express a various set of transcription factors-Sox17, Myt1, Yy1, Myrf and Zfp191,9-13 too as new membrane markers for example Gal-C, CNPase, MBP, PLP, MAG and MOG.4-17 The mature OLs take on a more complex morphology, forming condensed myelin sheaths around adjacent axons for metabolic support and functional conduction. Epigenetic modifications represent an additional layer of regulation of OL differentiation.
