Cavenee is regarded for having provided the first indisputable evidence of tumor suppressor genes. He has conducted research that has changed the knowledge of tumor progression and initiation. Dubbed the ‘Kinase King,’ Hunter's work identified among the critical switches required to initiate normal cell proliferation, and showed that the enzyme tyrosine kinase switch is frequently permanently turned on in cancer cells. His work has led to the discovery and development of several effective drugs targeting abnormal kinase signaling in cancers cells. A widely recognized expert in understanding the genetic instability of cancer cells and just why tumors become resistant to medications, Wahl's analysis showed that such instability often outcomes from mutations in key tumor suppressor genes such as for example p53.Performance of the Gene-Expression Classifier Figure 1Figure 1Functionality of the Gene-Expression Classifier , According to the Final Histopathological Diagnoses for Cytologically Indeterminate Samples. Summarizes the scientific performance characteristics for all relevant sample groups. Of the 265 indeterminate fine-needle aspirates, 85 were categorized as malignant on blinded histopathological review. For nodules classified as atypia of undetermined significance, the sensitivity was 90 percent and the specificity was 53 percent . For nodules classified as follicular lesions or neoplasms suspicious for follicular neoplasm, the sensitivity was 90 percent and the specificity was 49 percent .
