POSTER - MITOCHONDRIAL FUNCTION AND CANCER
Author: Douglas C. Wallace
This Poster highlights some recent discoveries that have led to a renewed interest in the function of mitochondria in cancer cells. Mitochondria carry out a number of crucial functions in cells and these can be altered through mutations in either the nuclear DNA or the mitochondrial DNA.

Here, epithelial splicing regulatory protein 1 is shown to generate a CD44 variant protein that enhances metastasis in a mouse model and protects cells from oxidative stress. | | | 06 Jun | Nat Commun 3:883 doi:10.1038/ncomms1892 (2012) | | | Biological sciences Cancer | | | Cell biology | | Abstract | Full Text | PDF (1,345 kB) |
