The main focuses of the lab are (1) to establish an early detection test for ovarian cancer (OVCA) using molecular-targeted ultrasound imaging in association with serum markers, and (2) to explore the prevention of OVCA incidence and its recurrence by enhancing anti-tumor immune function through dietary supplements. In addition, our lab is also exploring the factors associated with the malignant transformation of uterine fibroids (leiomyoma, a benign tumor) to leiomyosarcoma, a lethal cancer of the uterus. Moreover, our lab is also involved in examining the tumor-induced immunosuppression in cervical cancer and its prevention.
Ovarian cancer is an aggressive and fatal malignancy of women with a heterogeneous source of origin including ovarian surface epithelium (OSE) or fimbrial surface epithelium (FSE). OVCA in most cases is detected at late stages with frequent recurrence and high case to death ratio among gynecological malignancies. In contrast, the 5-year survival rates of OVCA patients increases to more than 90% when it is detected at early stages. However, early detection of OVCA is happenstance as the symptoms are non-specific at early stage and no test for effective early detection of OVCA is available. Serum levels of CA-125 alone or in combination with traditional ultrasound imaging are the currently used tests for OVCA detection. Serum levels of CA-125 are not specific for early OVCA. In addition, the resolution of traditional ultrasound imaging is limited and cannot detect early changes associated with ovarian malignancy. Moreover, no target(s) in the ovary indicative of malignant transformation to be detected by ultrasound imaging has been established. Thus, an effective early detection test for OVCA is urgently needed. Our early detection of OVCA project determines the expression of tumor-associated protein markers by the ovary and determines if these proteins are shed into the serum. Our laboratory develops imaging agents to test the feasibility of these markers as targets to be imaged by molecular-targeted ultrasound imaging. Subsequently, prevalence of these marker(s) in serum are determined. Using a preclinical model of spontaneous OVCA (laying hens), the ability of these serum and imaging markers are being tested for early detection of OVCA.
Tumor-induced immunosuppression is one of the hallmarks of tumor progression. Natural Killer (NK) cells are the first line of defense against a developing tumor. The mode of dissemination of OVCA differs from other cancers in that it spreads through diffusion in the peritoneal cavity. Thus, local immune function plays a critical role in preventing OVCA metastasis. However, the tumor evolves mechanisms to avoid NK-cell mediated anti-tumor immunity. Our laboratory is examining the efficacy of natural product supplementation in enhancing anti-tumor immune functions of NK cells.
Uterine fibroids are benign tumors of women of reproductive age commonly associated with heavy bleeding and extreme pain. Moreover, a subset of these benign tumors develops to lethal malignant leiomyosarcoma. Our laboratory examines the factors associated with transformation of uterine fibroids to leiomyosarcoma and prevention of fibroid incidence using a spontaneous preclinical model.
Our work
Current projects in our laboratory:
- Ovarian cancer: a) Factors associated with malignant transformation of the ovary and fimbria of fallopian tube; b) Early detection of ovarian cancer by serum markers and molecular-targeted ultrasound imaging; c) Prevention of ovarian tumor-induced immunosuppression by dietary supplementation of Ashwagandha.
- Uterine leiomyosarcoma: Uterine fibroids are benign tumors of women of reproductive age. A subset of these tumors become uterine leiomyosarcoma, a highly lethal malignant tumor of the uterus. This project explores the causative pathways leading to this malignant transformation.
- Cervical cancer: Progression of cervical cancer is facilitated by immunosuppression in the tumor microenvironment. This project explores tumor-induced expression of immunosuppressive receptors and their effects on tumor induced immunosuppression.
- Endometriosis: Endometriosis is a pathological condition of female reproductive organs which affects reproductive functions, a risk factor for development of cancer and required pain medication. This project explores the expression of receptors for non-opioid medication to control pain associated with endometriosis.
