Transcriptional and Epigenetic Regulation in Development and Disease

My laboratory has been interested in Epigenetic Regulation orchestrated by DNA methylation and posttranslational modifications of histone proteins. In the past years, we studied important epigenetic regulators which control viral replication, tumor malignancy and embryonic development.

The major contributions of Juan Lab include 1. Viral proteins inhibited host histone modifying enzyme activity and hijacked host chromatin assembly factor for viral replication (EMBO 2004, JBC 2009, Cell Res 2011, Oncogene 2012); 2. Histone demethylase RBP2 recognized specific DNA sequences (Nat Struc Mol Biol 2008, GRC major discovery, highlighted by Academia Sinica and A-IMBN) and promoted lung tumor malignancy depending on its enzymatic and DNA binding activities (Cancer Res 2013); 3. O-GlcNAc transferase (OGT) glycosylated and stabilized histone methyltransferase EZH2 for tumor suppressor gene silencing (PNAS 2014, GRC major discovery); 4. The acetylase N-a-acetyltransferase 10 protein (Naa10p) promoted lung tumorigenesis (J Clin Invest 2010, GRC major discovery, highlighted by Academia Sinica and A-IMBN) and genomic imprinting (Mol Cell, accepted) by facilitating DNA methyltransferase 1 (DNMT1) function; 5. DNA demethylation enzyme TET1 was a tumor suppressor by activating tissue inhibitors of matrix metalloproteinases (Best 5 Article in Cell Reports 2012, highlighted by Cell and Cell Reports websites, GRC major discovery).

In next five years, we have a few directions:

  1. DNA methylation regulator Naa10p in embryonic development, adipogenesis and brain disease. Naa10p is oncogenic and its mutations cause severe developmental delay including intellectual disability and infant death.
  2. DNA demethylase TET family proteins in DNA damage response and cancer suppression.
  3. Epigenetics and protein glycosylation
  4. Novel epigenetic marks in DNA and histones.
