Ovarian cancer (OC) is the fourth most common cancer in women, and the most lethal gynecologic malignancy in the United States. Adequate screening methodologies are currently lacking and most women first present with either stage III or IV disease. To date, there has been no substantial decrease in death rates and the majorities of patients relapse and die from their disease despite response to first-line therapy. Several proteins, such as CA-125, are elevated …

Chronic Stress Promotes Tumor Growth Through Increased Bdnf Production And Neo-Innervation, Julie K. Allen

Dissertations & Theses (Open Access)

Background: Activation of the sympathetic nervous system (SNS) in response to chronic biobehavioral stress results in high levels of catecholamines and persistent activation of adrenergic signaling, which promotes tumor growth and progression. However it is unknown how catecholamine levels within the tumor exceed systemic levels in circulation. I hypothesized that neo-innervation of tumors is required for stress-mediated effects on tumor growth.

Results: First, I examined whether sympathetic nerves are present in human ovarian cancer samples as well as orthotopic ovarian cancer models. Immunohistochemical (IHC) staining for neurofilament revealed that catecholaminergic neurons are present within tumor tissue. In order to determine …
