Laboratory of Transcriptional Regulation in Leukemogenesis

Research Field

Hematopoiesis, Transformation, Transcription factors, Epigenetics

Research Interests

To understand how hematopoietic stem cells develop myeloid malignancies:  Myelodysplastic syndrome (MDS) is a group of clonal disorders characterized by ineffective hematopoiesis, peripheral blood cytopenias, dysplastic cells in one or more hematopoietic lineages and a predisposition to acute myeloid leukemia (AML).  Given that MDS is phenotypically and genetically heterogeneous, the precise molecular mechanism of the development of MDS is incompletely understood.  High-throughput genome sequencing studies have identified various mutations of epigenetic modifiers in patients with MDS.  Aging is characterized by clonal myeloid-biased hematopoiesis and increases the risk of myeloid malignancies including MDS.  Recently, the mutations in epigenetic regulators were identified in normal elderly adults with clonal hematopoiesis.  Therefore, the accumulation of epigenetic alteration can provide pre-MDS HSCs and facilitate the initiation and propagation of MDS.  Our laboratory is working to determine how genetic and epigenetic alterations collaborate to promote the development of myeloid malignancies by utilizing comprehensive approaches (e.g. genetically modified mice, sequencing analysis).  Several areas of current investigation in the lab include:

  1. Functional understanding of the effect of mutations in transcription factors and epigenetic regulators in MDS and AML
  2. Understanding the functional role of numerical chromosomal anomalies in the development of myeloid malignancies

 

Biography

Goro Sashida recieved his MD from Tokyo Medical University in 1996.  He then undertook his PhD in medicine under the supervision of Dr. Kazuma Ohyashiki at the Department of Hematology, Tokyo Medical University in 2002.  In 2005, he joined Dr. Stephan Nimer's laboratory at Memorial Sloan-Kettering Cancer Center (New York, USA).  In 2009, he moved to Dr. Gang Huang's laboratory at Cincinnati Children's Hospital Medical Center (Ohio, USA), where he became interested in the study of epigenetic alteration in leukemia.  In 2010, he went back to Japan and joined Dr. Atsushi Iwama's laboratory at Chiba University (Chiba, Japan).  In 2015, He established his own research group "Laboratory of Transcriptional Regulation of Leukemogenesis" at International Research Center of Medical Sciences, Kumamoto University.
