Webb6 sep. 2011 · Introduction. In the history of evolutionary biology, Hugo de Vries is known as a proponent of the mutation theory of evolution, in which new species are believed to arise by single mutational events (de Vries 1901–1903, 1909, 1910).This theory is based on the breeding experiment he conducted for 13 years with the evening primrose Oenothera … Webb21 juli 2024 · In: In the Cell What is a mutation?

WebbIt has been shown that p53 mutations in mouse skin arise as early as one week of chronic UV-irradiation and the frequency of p53 mutations reach a maximum at 4–8 week of UV exposure. These results suggest that p53 mutations arise well before skin cancer development and that they can serve as a surrogate early biological endpoint in skin …
Webb2 jan. 2024 · The two β-arrestins (β-arrestin-1 and -2; alternative names: arrestin-2 and -3, respectively) are well known for their ability to inhibit signaling via G protein-coupled receptors. However, β-arrestins can also act as signaling molecules in their own right.
