AB  - Breast cancer molecular heterogeneity has resulted in disparities in therapeutic 
      response and targeting of molecular subtypes of breast cancer. This necessitates 
      identification and validation of novel therapeutic targets for breast cancer
      treatment. Suppression of Popeye domain-containing (POPDC) proteins is
      hypothesized to promote malignant cell behaviour and poor clinical outcomes in
      various cancers. We aimed to determine whether POPDC proteins are suppressed in
      human ductal carcinoma tissues and if this correlates to clinical progression and
      Her2 status. We further assessed if the EGFR regulated POPDC1 in breast cancer.
      Here we show significant suppression of POPDC1 in malignant breast cancer tissues
      without correlation to clinical progression. Interestingly, POPDC2 and POPDC3
      were highly expressed in malignant breast tissues. Furthermore, HER2+ status
      significantly correlated with high POPDC2 and POPDC3, but not POPDC1 expression. 
      We further show for the first time that low POPDC1 correlates to high EGFR
      expression in breast cancer tissues and that EGFR negatively regulates POPDC1
      expression in MCF7, MDA231 and SKBR3 breast cancer cells. Furthermore,
      overexpression of POPDC1 in MCF7, MDA231 and SKBR3 cells attenuated EGF-mediated 
      cell migration and proliferation. These findings show that POPDC1 is suppressed
      in breast cancer and can potentially be targeted to inhibit EGFR-mediated cell
      migration and proliferation.
