The Transcriptional Landscape of p53 Signalling Pathway
Although recent cancer genomics studies have identified a large number of genes that were mutated in human cancers, p53 remains as the most frequently mutated gene. To further elucidate the p53-signalling network, we performed transcriptome analysis on 24 tissues in p53+/+ or p53-/- mice after whole-body X-ray irradiation. Here we found transactivation of a total of 3551 genes in one or more of...
متن کاملhedgehog signalling pathway: carcinogenesis and targeted therapy
hedgehog signalling pathway has not only a critical role in cell proliferation, differentiation and tissue polarity at embryonic period but also has a vital role in stem cell proliferation, tissue healing and carcinogenesis. recent research has increased our understanding of this pathway and its relation to other signalling pathways. in addition, a large number of studies confirmed the alterati...
متن کاملDifferential regulation of the REGγ–proteasome pathway by p53/TGF-β signalling and mutant p53 in cancer cells
Proteasome activity is frequently enhanced in cancer to accelerate metastasis and tumorigenesis. REGγ, a proteasome activator known to promote p53/p21/p16 degradation, is often overexpressed in cancer cells. Here we show that p53/TGF-β signalling inhibits the REGγ-20S proteasome pathway by repressing REGγ expression. Smad3 and p53 interact on the REGγ promoter via the p53RE/SBE region. Converse...
متن کاملThe insulin signalling pathway
A significant stress faced by all animals is the unpredictable cycle of feeding and then starvation that ensues between meals. Humans solve this problem by storing nutrients in forms that can be used as energy sources during periods of fasting. The driving force that regulates this process is insulin, a hormone released by the β-pancreatic islet cells in response to elevated levels of nutrients...
متن کاملThe transcriptional landscape of the mammalian genome.
This study describes comprehensive polling of transcription start and termination sites and analysis of previously unidentified full-length complementary DNAs derived from the mouse genome. We identify the 5' and 3' boundaries of 181,047 transcripts with extensive variation in transcripts arising from alternative promoter usage, splicing, and polyadenylation. There are 16,247 new mouse protein-...
