Gene thought to assist chemo may help cancer thrive

...l can't be repaired, p53 starts a process known as apoptosis that kills the cell. It's p53's role as one of the genes involved in initiating cell death that has led cancer researchers to long believe that the gene is essential to successful chemotherapy. The idea is that p53 assists in killing the cancerous ce...

Despite the fact that various models of Nod1 activation have been described, little has been known about other proteins that might affect the protein’s activation. In contrast, a number of additional proteins have been linke...
