Dr. Cardinale's research is focused on understanding the mechanisms of gene expression and gene regulation in autoimmune diseases, including inflammatory bowel disease, type 1 diabetes, and systemic sclerosis. He uses data from large-scale genomic studies to identify disease-causing genetic variants and functionally explore the target genes of those variants.
Autoimmune diseases have a complex mode of inheritance, with studies showing that siblings and family members of people with diseases like Crohn’s, ulcerative colitis, and diabetes have a significantly increased risk of being affected, yet the pattern does not fit the simple single-gene model. Rather, these conditions, like most human traits, are influenced by hundreds of small single nucleotide polymorphisms (SNPs) located in the 99% of the genome that does not encode protein.
Presumably, these causal SNPs alter transcription protein binding, resulting in changes in the expression level of protein- and RNA-coding genes in specific contexts and cell types. A powerful approach to identify culprit SNPs is the genome-wide association study (GWAS), which compares millions of SNPs in affected individuals to a control population.
Dr. Cardinale's research focuses on characterizing the protein- and RNA-coding genes whose expression is altered by the disease-causing SNPs and the mechanism by which transcription factors recognize the SNPs to produce changes in gene expression. He recently examined a causal SNP for inflammatory bowel disease (IBD) in the promoter region of the Janus kinase 2 (JAK2) gene. Using CRISPR/Cas9 genome editing, he determined that JAK2 expression is only minimally impacted by the SNP, but this results is large changes in the function of the JAK-STAT signaling pathway in helper T cells. Using mass spectrometry, Dr. Cardinale identified the transcription factors, CUX1 and RBPJ, which bind differentially to the risk and non-risk alleles of the SNP.
Among his accomplishments, Dr. Cardinale:
- Found an enrichment of functionally defective coding variants in Decoy Receptor 3 (TNFRSF6B) in early-onset IBD
- Studied function of hereditary mutation in NOTCH4 receptor in familial systemic sclerosis
- Performed transcriptomic and pathway-based analysis of gene expression and genetic risk in ulcerative colitis
- Studied mechanism and consequence of noncoding polymorphism in JAK2 promoter in Jurkat T cells
