Job Openings

Postdoctoral Position: Postdoctoral opening is available in the Department of Biological Sciences, in conjunction with the Center of Biomedical Research Excellence (COBRE) in Matrix Biology, at Boise State University to study the molecular mechanisms of inflammatory cytokines in tumor cell-mediated extracellular matrix disruption resulting in breast cancer invasion and metastasis. This is a unique opportunity to join a team, which in addition to performing in vitro and in vivo investigations, is actively involved in clinical and translational studies and promotes cross-disciplinary collaboration in cell biology, molecular biology, biochemistry, biophysics, and biomaterials. Applicants should be independent, highly motivated individuals with a strong molecular, cellular, and biochemistry background and excellent research qualifications. Experience with animal models of cancer, confocal imaging, and in silico screening are preferred. Successful candidates must hold a doctoral degree, have a good publication record, and demonstrate excellent writing skills. Interested applicants should submit a CV, a brief statement of research skills/experience, and future goals. In addition, please provide contact information (including email addresses and phone numbers) for three references to: Dr. Cheryl L. Jorcyk,

Lab Research Interests

My laboratory’s research interests are directed towards elucidation of the molecular mechanisms that promote tumor progression. We have been working on the effects of the cytokine Oncostatin M (OSM) on breast tumor progression and metastasis. Oncostatin M (OSM), an IL-6 family cytokine, is produced by breast cancer cells and tumor-associated cells of the immune system, including macrophages and neutrophils. OSM has been shown to inhibit the proliferation of breast cancer cells, and this effect initially focused much attention on OSM as a potential breast cancer therapy. Data from our lab, however, suggests that OSM could actually contribute to tumor progression and the development of a metastatic state. We have shown that OSM induces vascular endothelial cell growth factor (VEGF), cyclooxygenase-2 (COX-2), cell detachment, and invasive capacity in vitro. In vivo studies have confirmed an important role for OSM in breast cancer metastasis to bone. Studies investigating OSM in prostate cancer are underway.
