  Background: Tumor-suppressor genes Tumour suppressor genes (TSG) are inactivated by methylation in several cancers including acute myeloid leukemia (AML). Transcriptional silencing of PRG2 gene could be involved in development and progression of cancers. 5-Azacytidine (5-Aza) is a DNA methyltransferase inhibitor that causes DNA de-methylation resulting in re-expression of silenced TSG. Midostaurin (PKC412) is a multitargeted tyrosine kinase inhibitor that potently inhibits FLT3 tyrosine kinase and induces hematological remission in patients with AML. However, majority of AML patients in clinical trials developed resistance to PKC412. Methods: Resistant cells were developed by overexposure of MV4-11 cells to PKC-412 and treated with 5-Aza. Apoptosis and cytotoxicity of PKC-412 were determined using Annexin V and MTS assays, respectively. Gene.. View More»
