‘Leading an initiative like this one, which is based on a solid platform of research, information technology, modern infrastructure, and nationwide collaboration in biomedical sciences, is totally aligned with the strategic strategy of the extensive study Institute of the MUHC.’ ‘That a public-private consortium involving the Canadian Institutes of Wellness Research and many large pharmaceutical businesses is supporting this study and facilitating the transfer of knowledge, from leads to actual patient treatments, underscores the importance of this extensive research,’ notes Dr. Bourbeau. ‘It is urgent that we use the tools of modern medicine to improve the span of this devastating disease, which has far too much stigma attached to it still.Discussion RAS was the initial oncogene discovered in which point mutations resulted in cellular transformation.29 Although RAS mutations alone bring about cellular senescence typically, in conjunction with other events that alter control of the cell cycle and apoptosis, they induce cellular transformation.30 Mutant RAS functions as a driver oncogene in one third of human cancers approximately.31 The prevalence of RAS mutations in sporadic cases of cutaneous squamous-cell carcinomas or keratoacanthomas isn’t known for sure but reportedly ranges between 3 and 30 percent.19,20 Our data indicate that RAS mutations are present in around 60 percent of cases in sufferers treated with vemurafenib, suggesting that preexisting mutations may confer a predisposition to the development of squamous-cell keratoacanthomas or carcinomas.12-14 Our functional studies showing HRAS-primed activation of the MAPK pathway in models of squamous-cell carcinoma treated with BRAF inhibitors provide proof that the toxicity linked to BRAF inhibition may arise from paradoxical MAPK-pathway activation.
