WAF1, a potential mediator of p53 tumor suppression
A gene is identified, named WAF1, whose induction was associated with wild-type but not mutant p53 gene expression in a human brain tumor cell line and that could be an important mediator of p53-dependent tumor growth suppression. Expand
Lessons from Hereditary Colorectal Cancer
The authors are grateful to the members of their laboratories for their contributions to the reviewed studies and to F. Giardiello and S. Hamilton for photographs of colorectal lesions. Expand
Identification of c-MYC as a target of the APC pathway.
The c-MYC oncogene is identified as a target gene in this signaling pathway and shown to be repressed by wild-type APC and activated by beta-catenin, and these effects were mediated through Tcf-4 binding sites in the c- MYC promoter. Expand
Constitutive Transcriptional Activation by a β-Catenin-Tcf Complex in APC−/− Colon Carcinoma
Constitutive transcription of Tcf target genes, caused by loss of APC function, may be a crucial event in the early transformation of colonic epithelium. Expand
High Frequency of Mutations of the PIK3CA Gene in Human Cancers
To determine if PI3Ks are genetically altered in tumorigenesis, they were sequenced in human for the first time and the results allowed us to assess the importance of phosphatidylinositol 3-kinases in neoplasia. Expand
Core Signaling Pathways in Human Pancreatic Cancers Revealed by Global Genomic Analyses
It is found that pancreatic cancers contain an average of 63 genetic alterations, the majority of which are point mutations, which defined a core set of 12 cellular signaling pathways and processes that were each genetically altered in 67 to 100% of the tumors. Expand
An Integrated Genomic Analysis of Human Glioblastoma Multiforme
Recurrent mutations in the active site of isocitrate dehydrogenase 1 (IDH1) occurred in a large fraction of young patients and in most patients with secondary GBMs and were associated with an increase in overall survival. Expand
Genetic instabilities in human cancers
There is now evidence that most cancers may indeed be genetically unstable, but that the instability exists at two distinct levels, and recognition and comparison of these instabilities are leading to new insights into tumour pathogenesis. Expand
Cancer Genome Landscapes
This work has revealed the genomic landscapes of common forms of human cancer, which consists of a small number of “mountains” (genes altered in a high percentage of tumors) and a much larger number of "hills" (Genes altered infrequently). Expand
Requirement for p53 and p21 to sustain G2 arrest after DNA damage.
After DNA damage, many cells appear to enter a sustained arrest in the G2 phase of the cell cycle. It is shown here that this arrest could be sustained only when p53 was present in the cell andExpand
