Excerpt

Anterior Gradient-2 was identified using proteomic technologies as a protein overexpressed in human cancers. We show here properties of AG2 suggesting it has proto-oncogenic properties:(i) the AG2 protein and gene are unregulated in a tamoxifen resistance panel of breast cancer cells lines, (ii) cell lines overproducing AG2 have an elevated clonogenic activity in vitro and also increase cell growth in a xenograft model, (iii) AG2 protein inhibits the tumour suppressor protein p53, and (iv) AG2 localizes to the endoplasmic reticulum, suggesting a proto-onocogenic signalling pathway exists from endoplasmic reticulum to the nucleus to inhibit p53. …
