Brief Biography
Dr.
Cho earned her B.A. degree from Yale University and her M.D. from Vanderbilt
University School of Medicine in 1980 and 1984, respectively. She performed
her Anatomic Pathology residency at the Johns Hopkins Hospital in Baltimore,
Maryland from 1984 to 1988, and served as Chief Resident in her final
year. From 1988 to 1990, she simultaneously served as Clinical Fellow
in the Johns Hopkins Department of Pathology and Research Fellow in the
Molecular Genetics Laboratory of the Johns Hopkins Oncology Center (under
the direction of Dr. Bert Vogelstein).
In 1990,
Dr. Cho became an Instructor in the Department of Pathology at Johns Hopkins
(Division of Gynecological Pathology, under the direction of Dr. Robert
Kurman). She was appointed an Assistant Professor in the Departments of
Pathology, Oncology, and Gynecology and Obstetrics in 1991, and was promoted
to Associate Professor in those Departments in 1995. In the Fall of 1998,
Dr. Cho joined the faculty of the Department of Pathology at the University
of Michigan.
Dr. Cho's
clinical interests are in gynecological pathology and she is a practicing
surgical pathologist with diagnostic expertise in this area. Her research
is aimed at elucidating the genetic alterations that underlie development
and progression of the common gynecological tumors (carcinomas of the
ovary, endometrium and uterine cervix).
A major
focus of her research group has been on cervical cancer, with an emphasis
on the molecular mechanisms by which human papillomaviruses contribute
to the development and/or progression of these tumors. Her group has previously
demonstrated that HPV-infected cells have altered cell cycle regulation,
including abrogation of the growth arrest that normally follows DNA damage.
These findings suggest a model of cervical tumorigenesis in which HPV-infected
cells are predisposed to the accumulation of somatic mutations in tumor
suppressor genes and/or oncogenes that are required for malignant transformation.
Additional ongoing studies are aimed at identifying and characterizing
novel genes involved in cervical tumorigenesis. The ultimate goal is to
contribute to the development of better strategies with which to diagnose,
treat, and/or prevent gynecological malignancies.
More recently,
the Cho laboratory has developed an ovarian cancer research program. Current
projects are aimed at 1) generating molecular (transcriptome and proteome)
profiles of large numbers of ovarian carcinomas in order to develop more
clinically informative tumor classification schemes; 2) identifying novel
genes amplified in ovarian carcinomas; and 3) characterization of the
Wnt/APC/ß-catenin/Tcf signaling pathway in a particular subtype
of ovarian carcinomas, namely, endometrioid adenocarcinomas.
