    Collapse Overview 
    Collapse overview
    Our lab aims to understand the molecular mechanisms by which cancer cells progress into advanced and malignant phenotypes. In particular, we focus on the role of the aryl hydrocarbon receptor (AhR) in prostate cancer progression. AhR is widely known for its role in mediating the harmful effects of a number of environmental toxins. However, evidence suggests that it may also play a key role in the progression of prostate cancer from castration dependent to castration independent. Specific goals of our lab are to:
    1. Determine the role of AhR in the development of castration independent prostate cancer via interaction with the androgen signaling pathway.

    2. Investigate the effects of environmental toxins (AhR agonist) on prostate cancer progression.

    3 Establish AhR as a potential therapeutic target in the treatment of castration independent prostate cancer.

    PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
