The Graduate Committee on Cancer Biology offers a program of study and research leading to the Ph.D. degree. A Master's degree is not offered. The curriculum in this graduate program has been designed to introduce students to the body of knowledge which encompasses the induction, properties, prevention, and therapy of cancer. In addition, the program has been designed to assure that the students have the necessary knowledge in one or more disciplines of fundamental science to enable them to carry out original research. Because the discipline of Cancer Biology is very broad-based (encompassing biology, molecular biology, biochemistry, pathology, pharmacology, immunology, and genetics) the curriculum requirements are flexible enough to provide the students opportunities to specialize in one of a number of areas including cancer etiology, altered regulation of proliferation and differentiation in cancer cell, prevention, and treatment of cancer. Students should have a B.S. or B.A. degree or an M.S. degree usually with a major in biochemistry or chemistry, molecular biology, genetics, cell biology, toxicology, or a closely related area, and have a cumulative grade-point average of at least 3.00. The background of the students should include basic courses in these areas as well as several advanced courses from chemistry, microbiology and immunology, molecular and cellular biology, biochemistry, genetics, pharmacology, and toxicology. Prior research experience is highly desirable and may be recognized in certain instances as evidence of competence in that area. All applicants must take the Graduate Record Examination. Subject GRE tests are optional. The deadline for receipt of application forms for fall admission is January 1. As part of the minimum 18 hours of course work in the major field, the graduate student is required to take Cancer Therapeutics (CBIO 555, 3 units), Molecular Mechanisms of Carcinogenesis (CBIO 551, 3 units), Cancer Biology Clinical Experience (CBIO 561, 2 units), Cancer Genetics (CBIO 589, 3 units), Biostatistics (EPID576a, 3 units), Science, Society and Ethics (MCB 596e, 1 unit), Laboratory rotations (CBIO 681, 4 units), Cancer Biology Colloquium (CBIO 595c, 1 unit each fall), and the Cancer Biology Seminar Series (CBIO 569h, twice for credit, 2 units total, although all students in the program are strongly encouraged to participate throughout their graduate careers)
