摘要: In Hodgkin lymphoma (HL) we recently identified deregulated expression of homeobox genes MSX1 and OTX2 which are physiologically involved in development the embryonal neural plate border region. Here, examined HL gene SIX1 an additional regulator this region mediating differentiation placodal precursors. was aberrantly activated 12 % patient samples silico, indicating a pathological role subset B-cell malignancy. addition, detected cell lines were used as models to reveal upstream factors target basic developmental regulator. We increased copy numbers locus at chromosome 14q23 correlating with enhanced while chromosomal translocations absent. Moreover, comparative profiling data pertinent modulation experiments indicated that WNT-signalling pathway transcription factor MEF2C regulate expression. Genes encoding GATA2, GATA3, SPIB – all lymphoid regulators - targets HL. cofactors EYA1 TLE4, respectively, contrastingly mediated activation suppression Thus, protein domain interfaces may represent therapeutic SIX1-positive subsets. Collectively, our regulatory network centrally deregulating support concordance lymphopoiesis/lymphomagenesis processes
