Research

The main research of this laboratory concerns molecular mechanisms of viral pathogenesis.

Fifteen percent of human cancers are associated with or caused by viruses. We are investigating if a virus similar to the mouse mammary tumor virus (MMTV) is involved in human breast cancer pathogenesis. We have found viral sequences similar to MMTV in 38% of the human breast cancers tested. They were expressed as RNA and proteins. A complete proviral structure has been detected with the characteristics of a replicative competent virus.

Recently, we isolated and characterized a beta retrovirus from primary cultures of human breast cancer cells. The retrovirus is able to infect epithelial and lymphocytic human cells. Its potential for malignant transformation is being investigated. Epidemiological studies on breast cancer and retroviral incidence are also carried out by analyzing samples from different geographical locations. The transcriptional profile of breast cancer cells carrying the virus was also investigated. Together, these studies will help to determine if a retrovirus is involved in human breast cancer pathogenesis.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Pogo did not report having any of the following types of financial relationships with industry during 2013 and/or 2014: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website at http://icahn.mssm.edu/about-us/services-and-resources/faculty-resources/handbooks-and-policies/faculty-handbook. Patients may wish to ask their physician about the activities they perform for companies.
