Tumor cell migration and invasion are critical initiation steps in the process of breast cancer metastasis, the primary cause of breast cancer morbidity and death. Here we investigated the role of p21Cip1 (p21), a member of the core cell cycle machinery, in transforming growth factor-beta (TGFβ)-mediated breast cancer cell migration and invasion. A mammary(More)
Deregulation of the cell cycle machinery is often found in human cancers. Modulations in the cell cycle regulator function and expression result not only in proliferative advantages, but also lead to tumor progression and invasiveness of the cancer. In particular, cyclin D1 and p21 are often over-expressed in human cancers, correlating with high tumor(More)
This study helps to define the implications of breast cancer anti-estrogen resistance 3 (BCAR3) in breast cancer and extends the current understanding of its molecular mechanism of action. BCAR3 has been shown to promote cell proliferation, migration and attachment to extracellular matrix components. However, in a cohort of metastatic breast cancer patients(More)
Erratum Main text: After publication of this work [1] an error was noticed in Fig. 5c. Figure 5c shows representative images/fields of PTGS2 staining of mammary tumors derived from mice injected with parental SCP2 cells versus mice injected with p21/cyclinD1 depleted SCP2 cells. Tissue slides from the two groups of animals were stained with an anti-PTGS2(More)
Erratum After publication of this work [1] an error was noticed in Fig. 3b. The tubulin Western blot control was accidentally used for both SCP2 and SCP25 cells. The corrected figure is shown below. We apologize for this error, which did not affect any of the interpretations or conclusions of the article. References 1. Dai M, et al. A novel function for(More)
Triple negative breast cancer (TNBC), an aggressive subtype of breast cancer, display poor prognosis and exhibit resistance to conventional therapies, partly due to an enrichment in breast cancer stem cells (BCSCs). Here, we investigated the role of the cyclooxygenase-2 (COX-2), a downstream target of TGFβ, in regulating BCSCs in TNBC. Bioinformatics(More)
Triple negative breast cancers exhibit very aggressive features and poor patient outcomes. These tumors are enriched in cancer stem cells and exhibit resistance to most treatments and chemotherapy. In this study, we found the cyclin-dependent kinase (CDK4) to act as a cancer stem cell regulator and novel prognostic marker in triple negative breast cancers.(More)
