Gene expression changes in REH following CDC42 inhibition
ARHGEF4 expression is associated with t(12;21) acute lymphoblastic leukaemia (ALL). Our study investigated the substrate specificity of ARHGEF4, a member of the diffuse B-cell lymphoma (DBL) family of guanine nucleotide exchange factors (GEFs), in t(12;21) ALL REH cells. ARHGEF4 was found to activate the small guanine nucleotide binding protein (GTPase) CDC42. In order to determine the function of CDC42 in t(12;21) ALL cells, we performed RNAseq analysis on REH cells treated for 24 hours with DMSO vehicle control in comparison to 25uM ML141, a CDC42 inhibitor. Overall design: Total cellular RNA was purified from DMSO and 25uM ML141 treated REH samples from three independent experiments
