Cancer is a class of diseases in which a group of cells display
uncontrolled growth, invasion, and sometimes metastasis.. Prostate
cancer is a form of cancer that develops in the prostate, a gland in the
male reproductive system. Most prostate cancers are slow growing.
However, there are cases of aggressive prostate cancers. The cancer
cells may metastasize from the prostate to other parts of the body,
particularly the bones and lymph nodes. Loss of PTEN and concomitant
activation of AKT could act in partnership with the TMPRSS2-ERG fusion
protein to promote progression to prostate cancer through downstream
pathways that increase the selective advantage of pre malignant
prostatic intraepithelial neoplasia cells.
