WebThe discovery of oncogenes was as mentioned originally made by the use of retroviruses. This infers that genetic control elements in the virus itself can be responsible for the abnormal expression of the oncogene. However, in many cases it was found that alterations of the transferred oncogene contributed to its accentuated expression. WebLikewise, many oncogenes, or growth-promoting genes, are mistakenly turned on, resulting in abnormal cell proliferation. In cancer cells, genes can be modified by mutations, which alter the function of the proteins that the genes encode. Through epigenetics, modifications to chromosomes take place and alter gene-expression patterns. improving lung functionWebWe show that miR-3928 exogenous expression leads to the degradation of multiple important oncogenes.
