A pioneer in the field of cancer genomics, his studies on colorectal cancers revealed that they result from the sequential accumulation of mutations in oncogenes and tumor suppressor genes. Figure 1 Vogelgram of colorectal cancer..63 Figure 2 Risk factors of colorectal cancer.64 Figure 3 Dietary recommendations to prevent CRC development..65 Figure 4 The beneficial physiological effects of dietary fiber and its underlying mechanisms The original “Vogelgram” (Fearon and Vogelstein, 1990) mapped loss of chromosome 5q, 12p, 18q, and 17p, and mutations on APC, K-RAS, DCC, and p53 in a sequential order of cancer progression, although the importance of mutation accumulation, rather than sequential order, was emphasized. DNA hypermethylation also was mapped in the early adenoma stage.

If this is correct, which of the following would be predicted? Since metastasis comes late, the cells that migrate to other tissues will have a lot of variety (i.e., be polyclonal), therefore, it will be more difficult to destroy them with single agents.

In 1990, Fearon & Vogelstein proposed the Vogelgram model of multi-step colon cancer pathogenesis.

2016-12-01 · Chromosomal instability (CIN) is represented by the classic “Vogelgram,” 12 beginning with an inactivating mutation in the gateway driver gene APC and progressing through other driver mutations in KRAS, SMAD4, and TP53. The APC mutation predisposes the cell to chromosomal instability, which leads to LOH and aneuploidy.

Bert Vogelstein is director of the Ludwig Center, Clayton Professor of Oncology and Pathology and a Howard Hughes Medical Institute investigator at The Johns Hopkins Medical School and Sidney Kimmel Comprehensive Cancer Center. A pioneer in the field of cancer genomics, his studies on colorectal cancers revealed that they result from the sequential accumulation of mutations in oncogenes and … ‘Vogelgram’ genes. In the present study, no significant differences in mRNA expression between adenomas and carcinomas were found for genes traditionally attributed to CRC development like APC, KRAS, TP53 and DCC . Drs. Weinberg and Vogelstein have authored numerous influential articles, including some that have become conceptual cornerstones of modern cancer research, namely, “Hallmarks of Cancer” by Dr. Weinberg, together with Dr. Douglas Hanahan, and “Vogelgram” by Dr. Vogelstein, which are complementary to each other.
