One focus of the lab is interrogating the human and mouse genomes for functional non-coding sequences. For example, we have used computational biology and next generation sequencing to identify thousands of conserved CArG boxes (CArGome), to which the SRF transcription factor binds. We have also pinpointed scores of CArG-SNPs that disrupt SRF binding and thus target gene expression. The latter have direct translational significance towards understanding complex human disease traits. The CArGome work has led us to the expansive class of long noncoding RNA genes and we recently reported one of the first human vascular cell-restricted lncRNAs (called SENCR). We continue to apply RNA-seq to the study of human vascular cells treated under a variety of experimental conditions for further identification of lncRNA genes. To test the functionality of noncoding sequences such as CArG boxes and lncRNA genes, we use the revolutionary CRISPR-Cas9 genome editing system. We recently reported the first ever unadulterated regulatory element mutation in mice wherein a CArG box was subtly changed to inhibit SRF binding; the result was a near complete erasure of target gene expression. This report paves the way for a new generation of studies that will use CRISPR-Cas9 to assess regulatory element function in a living animal. The lab has many CRISPR-Cas9 mouse projects underway, including the modeling of human SNPs linked to disease.
