Research Interest

  • Development of target specific nanotherapeutics for epigenetic regulation of cancer. Chemoprevention and mechanism of action of drug/siRNA loaded nanoparticle mediated therapy for leukemia, neuroblastoma and glioblastoma. New drug development from natural products and combination therapy against cancer. Development and application of high-throughput functional gene-based screening for cancer. Multiple retrovirus and lentivirus mediated gene delivery for target validation and functional implication in cancer.

Research Highlights

  • Dr. Subhasree Roy Choudhury’s research group works on neuroprotective efficacy of nature inspired biocompatible polydopamine nanocarrier for metformin delivery (Met encapsulated PDANPs) by crossing blood brain barrier in in vitro, 3D and in vivo experimental Parkinson’s disease models. The neuroprotective mechanism proved novel interaction of epigenetic regulator EZH2 mediated ubiquitination and proteasomal degradation of aggregated pSer129 α-Syn. This study divulges the neuroprotective role of Met loaded PDANPs by reversing the neurochemical deficits by confirming an epigenetic mediated nanotherapeutic approach for the PD prevention.

  • Dr. Subhasree Roy Choudhury and group have recently shown that Polycomb protein Bmi1 is associated with advanced prognosis of acute myeloid leukemia (AML). Polyethylenimine (PEI)-stabilized Bmi1 siRNA-entrapped human serum albumin (HSA) nanocarriers (PEI@HSANCs) were used to protect siRNA from degradation and for epigenetic regulation-based AML therapy. Nanoform increased the transfection efficiency of Bmi1 siRNA through caveolae-mediated endocytosis and enhanced Bax translocation into the mitochondria, enhanced caspase 3-mediated apoptosisand inhibited Bcl2. The molecular analysis reveals the downregulation of polycomb proteins, Bmi1 and EzH2, along with inhibition of H3K27me3 and H2AK119ub1 through ubiquitin-mediated degradation of Bmi1, which is reversed by a proteasome inhibitor. Further mechanistic studies by Chromatin immunoprecipitation (ChIP) assay established a crucial role of transcription factor, C-Myb and Bmi1, as its direct targets for maintenance and progression of AML. Decreased leukemic stem cells marker (CD45+) and an increase in the myeloid differentiating marker expression (CD11b+) in the bone marrow,withdrawal of epigenetic repression through ubiquitin proteasomal pathway potentiating a novel antileukemic therapy were established in in vivo AML xenograft model.
