Investigation of candidate molecular biomarkers for expression profile analysis of the Gene expression omnibus (GEO) in acute lymphocytic leukemia (ALL).

Much progress has been made in understanding the mechanism of acute lymphocytic leukemia (ALL). However, for adult ALL, there is still a lack of an effective treatment. In the present study, we first used the Gene Expression Omnibus (GEO) database to identify differentially expressed genes (DEGs) between ALL cell lines and Hodgkin and non-Hodgkin cell lines. Then, the GEO database was also used to detect the DEGs in acute lymphoblastic leukemia (Reh) cells transfected with a normal control or a constitutively active variant of the IkB kinase β. Finally, we found that three key DEGs (CCL5, FSCN1, and HS3ST1) are involved in proliferation and apoptosis according to Gene Ontology (GO) and Kyoto Encyclopedia of Genes Genomes (KEGG) pathway analyses. Finally, we determined that all three target genes that participate in proliferation and apoptosis are regulated via the NF-kB signaling pathway.
