The ANX7 gene codes for a Ca2+-activated GTPase, which has been implicated
in both exocytotic secretion in cells and control of growth. In this review
, we summarize information regarding increased tumor frequency in the Anx7
knockout mice, ANX7 growth suppression of human cancer cell lines, and ANX7
expression in human tumor tissue micro-arrays. The loss of ANX7 is signifi
cant in metastatic and hormone refractory prostate cancer compared to benig
n prostatic hyperplasia. In addition, ANX7 expression has prognostic value
for predicting, survival of breast cancer patients.
