Albano et al. Molecular Cancer 2013, 12:36 http://www.molecular-cancer/content/12/1/SHORT COMMUNICATIONOpen AccessGene expression profiling of chronic myeloid leukemia with variant t(9;22) reveals a diverse signature from situations with classic translocationFrancesco Albano*, Antonella Zagaria, Luisa Anelli, Nicoletta Coccaro, Luciana Impera, Crescenzio Francesco Minervini, Angela Minervini, Antonella Russo Rossi, Giuseppina Tota, Paola Casieri and Giorgina SpecchiaAbstractBackground: The t(9;22)(q34;q11) producing the BCR/ABL1 fusion gene represents the cytogenetic hallmark of chronic myeloid leukemia (CML). About 50 of CML cases show variant translocations together with the involvement of other chromosomes as well as chromosomes 9 and 22. The molecular bases of biological variations between CML individuals with classic and variant t(9;22) have under no circumstances been clarified. Findings: Within this study, we performed gene expression microarray analysis to evaluate CML individuals bearing variant rearrangements and those with classic t(9;22)(q34;q11). We identified 59 differentially expressed genes substantially associated with all the two analyzed groups. The function of distinct candidate genes including TRIB1 (tribbles homolog 1), PTK2B (protein tyrosine kinase two beta), and C5AR1 (complement element 5a receptor 1) is discussed. Conclusions: Our outcomes reveal that in CML circumstances with variant t(9;22) there is an enhancement from the MAPK pathway deregulation and show that kinases are a typical target of molecular alterations in hematological disorders.
