The Campbell lab examines how regulatory elements present in RNA coordinate gene expression in humans. To do so, we have pioneered new genomic approaches to overcome technical limitations in comprehensive analysis of RNA-binding using next-generation sequencing. Our ultimate goal is to translate these findings to a multitude of outstanding problems that will inform our understanding of development and disease.

Jonathan E. Ploski, PhD

Anxiety Disorders affect about 40 million American adults age 18 years and older (about 18%) in a given year, causing them to be filled with fearfulness and uncertainty. While each anxiety disorder has different symptoms, all the symptoms cluster around excessive, irrational fear. Currently the neurobiological basis for these disorders remains poorly understood and treatments for these disorders remain inadequate. Therefore research in my laboratory focuses on identifying the molecular and biochemical mechanisms that contribute to the development of fear and the maintenance of fear.

Collectively my laboratory utilizes a myriad of molecular, biochemical and behavioral approaches to study learned fear (cue-induced anxiety) and innate fear. In particular we manipulate gene expression within the rodent brain utilizing recombinant viruses to establish respective roles for individual genes/proteins in neural plasticity, memory formation and anxiety.

Research in the lab is centered on understanding the molecular mechanisms regulating neurodegeneration.  Specifically, primary cultures of neurons, transgenic and knockout mice, and animal models of neurological disease are used to study genes, proteins, and signal transduction pathways regulating neuronal cell death.  We are also interested in identifying chemical compounds that protect the brain from neurodegeneration. The long-term objective of the laboratory’s research is to develop strategies to prevent, treat, or cure degenerative diseases of the brain.  Recently, we have expanded our interests to investigate neurodevelopmental disorders.

Our lab takes genomics approaches to decipher the functions of cancer-relevant transcription factors in breast, lung and prostate cancer and to translate this knowledge into new approaches for detection and treatment of cancer:

  1. We combine analyses of the genomic binding sites of cancer-relevant transcription factors, epigenetic, gene expression and clinical outcome data to make specific predictions about the role of transcription factors and functional interaction of multiple transcription factors in the regulation of cancer-relevant gene networks
  2. We use RNAi screening to identify druggable modulators of transcription factors whose direct therapeutic targeting is challenging as molecules for targeted therapies.
  3. We analyze the expression of the target genes of oncogenic transcription factors in tissues and serum of cancer patients to identify novel biomarkers.

Mouse genetics to delineate the genetic basis for autoimmune disease pathogenesis. Our primary focus has been on systemic lupus erythematosus (SLE), a debilitating autoimmune disease initiated via a profound loss of immunologic tolerance to nuclear antigens. We have used genetic manipulation of the lupus-prone NZM2410 murine model of SLE to dissect SLE pathogenesis into a series of discrete stages.

We are currently in the process of identifying the individual susceptibility genes and defining the genetic pathways responsible for the initiation and progression of systemic autoimmunity in lupus-prone mouse models of SLE. Additional projects within the laboratory include genetic dissections of autoimmune diabetes and the analysis of a variety of polymorphisms in normal immune functions. The use of microarray technology in combination with genetic fine mapping to identify polymorphic genes with potent immunologic effects is a major new thrust within the laboratory.
