Angiopoietin receptor TEK mutations underlie primary congenital glaucoma with variable expressivity.
Journal of Clinical Investigation 126(7):2575 (2016)
Primary congenital glaucoma (PCG) is a devastating eye disease and an important cause of childhood blindness worldwide. In PCG, defects in the anterior chamber aqueous humor outflow structures of the eye result in elevated intraocular pressure (IOP); however, the genes and molecular mechanisms i...

Oncotarget 7(11):12386 (2016)
Activation of Wnt signaling due to Wnt overexpression or mutations of Wnt pathway components is associated with various cancers. Blocking Wnt secretion by inhibiting PORCN enzymatic activity has shown efficacy in a subset of cancers with elevated Wnt signaling. Predicting response to upstream Wn...
TEX11 is mutated in infertile men with azoospermia and regulates genome-wide recombination rates in mouse.
Embo Molecular Medicine 7(9):1198 (2015)
Genome-wide recombination is essential for genome stability, evolution, and speciation. Mouse Tex11, an X-linked meiosis-specific gene, promotes meiotic recombination and chromosomal synapsis. Here, we report that TEX11 is mutated in infertile men with non-obstructive azoospermia and that an ana...
Regulatory crosstalk between lineage-survival oncogenes KLF5, GATA4 and GATA6 cooperatively promotes gastric cancer development.
Gut 64(5):707 (2015)
Gastric cancer (GC) is a deadly malignancy for which new therapeutic strategies are needed. Three transcription factors, KLF5, GATA4 and GATA6, have been previously reported to exhibit genomic amplification in GC. We sought to validate these findings, investigate how these factors function to pr...

Genome Biology 16(1):32 (2015)
Colorectal cancer with metastases limited to the liver (liver-limited mCRC) is a distinct clinical subset characterized by possible cure with surgery. We performed high-depth sequencing of over 750 cancer-associated genes and copy number profiling in matched primary, metastasis and normal tissue...
Mutational landscapes of tongue carcinoma reveal recurrent mutations in genes of therapeutic and prognostic relevance.
Genome Medicine 7(1):98 (2015)
Carcinoma of the oral tongue (OTSCC) is the most common malignancy of the oral cavity, characterized by frequent recurrence and poor survival. The last three decades has witnessed a change in the OTSCC epidemiological profile, with increasing incidence in younger patients, females and never-smok...
Sequencing the mouse Y chromosome reveals convergent gene acquisition and amplification on both sex chromosomes.
Cell 159(4):800 (2014)
We sequenced the MSY (male-specific region of the Y chromosome) of the C57BL/6J strain of the laboratory mouse Mus musculus. In contrast to theories that Y chromosomes are heterochromatic and gene poor, the mouse MSY is 99.9% euchromatic and contains about 700 protein-coding genes. Only 2% of th...
Mammalian Y chromosomes retain widely expressed dosage-sensitive regulators.
Nature 508(7497):494 (2014)
The human X and Y chromosomes evolved from an ordinary pair of autosomes, but millions of years ago genetic decay ravaged the Y chromosome, and only three per cent of its ancestral genes survived. We reconstructed the evolution of the Y chromosome across eight mammals to identify biases in gene ...
Massively parallel sequencing of patients with intellectual disability, congenital anomalies and/or autism spectrum disorders with a targeted gene panel.
PLoS ONE 9(4):e93409 (2014)
Developmental delay and/or intellectual disability (DD/ID) affects 1-3% of all children. At least half of these are thought to have a genetic etiology. Recent studies have shown that massively parallel sequencing (MPS) using a targeted gene panel is particularly suited for diagnostic testing for...
Regionally-specified second trimester fetal neural stem cells reveals differential neurogenic programming.
PLoS ONE 9(9):e105985 (2014)
Neural stem/progenitor cells (NSC) have the potential for treatment of a wide range of neurological diseases such as Parkinson Disease and multiple sclerosis. Currently, NSC have been isolated only from hippocampus and subventricular zone (SVZ) of the adult brain. It is not known whether NSC can...
Nanoscale chromatin profiling of gastric adenocarcinoma reveals cancer-associated cryptic promoters and somatically acquired regulatory elements.
Nature Communications 5:4361 (2014)
Chromatin alterations are fundamental hallmarks of cancer. To study chromatin alterations in primary gastric adenocarcinomas, we perform nanoscale chromatin immunoprecipitation sequencing of multiple histone modifications in five gastric cancers and matched normal tissues. We identify hundreds o...
Mutations inSCO2Are Associated with Autosomal-Dominant High-Grade Myopia
The American Journal of Human Genetics 92(5):820 (2013)
Myopia, or near-sightedness, is an ocular refractive error of unfocused image quality in front of the retinal plane. Individuals with high-grade myopia (dioptric power greater than −6.00) are predisposed to ocular morbidities such as glaucoma, retinal detachment, and myopic maculopathy...
CYP1B1, MYOC, and LTBP2 mutations in primary congenital glaucoma patients in the United States.
American Journal of Ophthalmology 155(3):508 (2013)
To screen primary congenital glaucoma patients in the United States for sequence variants within the CYP1B1, LTBP2, and MYOC genes using Sanger and whole exome sequencing.
Retrospective case-control study.
Fifty-seven primary congenital glaucoma patients (47 families), 71 unaffected family membe...
mTORC1 inhibition restricts inflammation-associated gastrointestinal tumorigenesis in mice.
Journal of Clinical Investigation 123(2):767 (2013)
Gastrointestinal cancers are frequently associated with chronic inflammation and excessive secretion of IL-6 family cytokines, which promote tumorigenesis through persistent activation of the GP130/JAK/STAT3 pathway. Although tumor progression can be prevented by genetic ablation of Stat3 in mic...
Host cell transcriptome profile during wild-type and attenuated dengue virus infection.
PLoS Neglected Tropical Diseases 7(3):e2107 (2013)
Dengue viruses 1-4 (DENV1-4) rely heavily on the host cell machinery to complete their life cycle, while at the same time evade the host response that could restrict their replication efficiency. These requirements may account for much of the broad gene-level changes to the host transcriptome up...
Methylation subtypes and large-scale epigenetic alterations in gastric cancer.
Science Translational Medicine 4(156):156ra140 (2012)
Epigenetic alterations are fundamental hallmarks of cancer genomes. We surveyed the landscape of DNA methylation alterations in gastric cancer by analyzing genome-wide CG dinucleotide (CpG) methylation profiles of 240 gastric cancers (203 tumors and 37 cell lines) and 94 matched normal gastric t...
TP53 genomic status regulates sensitivity of gastric cancer cells to the histone methylation inhibitor 3-deazaneplanocin A (DZNep).
Clinical Cancer Research 18(15):4201 (2012)
DZNep (3-deazaneplanocin A) depletes EZH2, a critical component of polycomb repressive complex 2 (PRC2), which is frequently deregulated in cancer. Despite exhibiting promising anticancer activity, the specific genetic determinants underlying DZNep responsiveness in cancer cells remain largely u...
