THE“VOGELGRAM” Cancer develops in a stepwise manner, and each step is associ-ated with changes at the molecular level. In 1990, Fearon and Vogelstein proposed a progressive development model of colon cancer and presented some of the key genetic changes associ-ated with the stages of progression (Fearon and Vogelstein,1990; Grady,2004

In 1990, Fearon and Vogelstein proposed a progressive development model of colon cancer and presented some of the key genetic changes associated with the stages of progression ( Fearon and Vogelstein, 1990 ; Grady, 2004 The classic Vogelgram described the multistep model for CRC pathogenesis outlining few critical events, in which the APC gene mutations permitted adenoma formation, activating mutations in the KRAS oncogene and genomic losses at chromosome 18 loci facilitated adenomatous growth, and inactivation of p53 triggered the final transition of adenoma For example, the observation that 17p and chromosome 18 were frequently lost in colorectal cancers 28 contributed crucially to the ‘Vogelgram’ model of colon cancer development 29, whereas it was not possible to correctly analyse the chromosome rearrangements of the HeLa cell line by banding 25. As a post-doctoral fellow, he showed that loss of heterozygosity (LOH) at 18q targeted the SMAD4 gene inactivation in colon cancer. As a result, the multi-step colon cancer progression model (i.e., “Vogelgram”) was revised to include SMAD4. Subsequently, he was involved in the identification of a family of five novel SMAD genes.

described a stepwise model of the adenoma-to-carcinoma sequence, implicating both genetic and epigenetic events in tumor carcinogenesis.2 The Vogelgram sequence is characterized by mul-tiple steps that involve different oncogenes (e.g. KRAS, NRAS, BRAF, and PIK3CA) and tumor suppressor genes (e.g. APC, TP53, SMAD4, and

This type of schematic presentation of the correlation between genetic/genomic changes and stages of colon cancer progression is nicknamed a “Vogelgram.” The model is widely accepted, and newer information from genomics, cytogenetics, and tumor mass sequencing is being added to advance our understanding (e.g., Wood et al., 2007; Chittenden et al., 2008; Brosens et al., 2010).

Effective data modeling should be a primary focus of any enterprise architect. By J The National Cancer Institute would like to hear from anyone with a bold idea to advance progress against childhood cancer by enhancing data sharing.

It can, however, form the schematic framework for mecha-nistic, quantitative models that incorporate more realistic properties of biological sys-tems such as stochasticity and nonlinearity. As the outcomes of such interactions cannot Emergence of invasive behavior in cancer is life-threatening, yet ill-defined due to its multifactorial nature. We present a multiscale mathematical model of cancer invasion, which considers cellular and microenvironmental factors simultaneously and interactively. Unexpectedly, the model simulations predict that harsh tumor microenvironment conditions (e.g., hypoxia, heterogenous extracellular 2020-10-14 · Organoid technology has rapidly transformed basic biomedical research and contributed to significant discoveries in the last decade. With the application of protocols to generate organoids from cancer tissue, organoid technology has opened up new opportunities for cancer research and therapy. Using organoid cultures derived from healthy tissues, different aspects of tumour initiation and Bert Vogelstein (born 1949) 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. For example, the observation that 17p and chromosome 18 were frequently lost in colorectal cancers 28 contributed crucially to the ‘Vogelgram’ model of colon cancer development 29, whereas it was not possible to correctly analyse the chromosome rearrangements of the HeLa cell line by banding 25.
