Project description:PU.1 is an Ets family transcription factor that is essential for the differentiation of both myeloid and lymphoid cells. PU.1 is down-regulated in classical Hodgkin lymphoma cells via methylation of the PU.1 promoter. To evaluate whether down-regulation of PU.1 is essential for the growth of cHL cells, we generated KM-H2 derived cell lines conditionally express PU.1 by tet-off system (designated KM-H2tetPU.1). Conditonally expressed PU.1 by tetracycline removal induced complete growth arrest and apoptosis in KM-H2 cells. To elucidate the mechanisms underlying cell cycle arrest and apoptosis induced by PU.1, we compared gene expression profiles of KM-H2tetPU.1 cells 0, 1 and 3 days after PU.1 induction, by DNA microarray.
Project description:Rhodamin 123 is a dye which can be used to detect the activity of ABC transporters. We observed that after staining of KM-H2 Hodgkin lymphoma cells with Rhodamin 123, part of the cells rapidly eliminated the dye, while another part of the cells retained the dye for a longer time. We compared the transcriptome of KM-H2 Hodgkin lymphoma cells with high Rhodamin 123 efflux capacity and KM-H2 cells with low Rhodamin 123 efflux capacity.
