Down Syndrome Works Against Cancer

DNAPeople born with Down syndrome have an extra copy of chromosome 21 which causes the genetic aberrations associated with the condition.  But chromosome 21 carries 231 genes, including some that may well suppress cancer. In a new study, researchers offered findings that the protein encoded by the RCAN1 gene helps to control the rampant blood vessel growth that tumors need.  Scientists speculate that, by having an extra copy of the gene, more protein is be made, adding to an anticancer effect.  For more information on this study, see here.
