Witryna13 kwi 2024 · Cancer risk factors alter tissue takeover. The selective advantage of cell phenotypes is not always cell autonomous and hence can be altered. For example, in the mouse epidermis, lineage tracing of cells harboring a Trp53R245W mutation expanded and colonized the epidermis up to 24 weeks post induction. The colonization may … WitrynaAccordingly, it is not surprising that heritable effects of irradiation have not been observable thus far in this population or in any other irradiated human population, in spite of exhaustive efforts to detect them. ... since it implies that even a small dose of radiation given to a large number of individuals may introduce mutant genes into ...
