INhibitor of Growth 1 (ING1) expression is repressed in breast carcinomas, but its role in breast cancer development and metastasis is unknown. ING1 levels were quantified in >500 patient samples using automated quantitative fluorescence immunohistochemistry, and data were analysed for correlations to patient outcome. Effects of altering ING levels were examined in microarrays and metastasis as...
Background and purpose: The aim of this study was to estimate the disease-free survival rate, in female patients with breast cancer and determining the level of influencing factors. Materials and methods: In a retrospective cohort study, the records of 377 patients attending Mashhad Omid hospital, Iran, spanning the years 2006 to 2011 were selected using convenience sampling. The patients we...
DLC1-dependent parathyroid hormone-like hormone inhibition suppresses breast cancer bone metastasis.
Bone metastasis is a frequent complication of breast cancer that is often accelerated by TGF-β signaling; however, little is known about how the TGF-β pathway is regulated during bone metastasis. Here we report that deleted in liver cancer 1 (DLC1) is an important regulator of TGF-β responses and osteolytic metastasis of breast cancer cells. In murine models, breast cancer cells lacking DLC1 ex...
Running Title: miR-196s act as metastasis suppressors Author manuscripts have been peer reviewed and accepted for publication but have not yet been edited. ABSTRACT Expression profiling has identified metastasis-associated miRNAs but technical limitations hinder the discovery of metastasis-suppressing miRNAs. In this study, we sought metastasis-suppressing miRNAs by functional screening. Indivi...
OBJECTIVE To observe the effects of metastasis-associated tumor gene family 2 (MTA2) depletion on human breast cancer cell proliferation and metastasis. METHODS A short-hairpin RNA targeting MTA2 was chemically synthesized and transfected into a lentivirus to construct Lv-shMTA2 for infection into the MDA-MB231 human breast cancer cell line. At 48 hours after infection cells were harvested an...
Leukemia inhibitory factor (LIF) is a multi-functional cytokine protein. The role of LIF in tumorigenesis is not well-understood. Here, we found that LIF promotes tumorigenesis and metastasis of breast cancer. LIF promotes cell proliferation and anchorage-independent growth of breast cancer cells in vitro, and the growth of xenograft breast tumors in vivo. LIF also promotes invasion and migrati...
MicroRNAs are well suited to regulate tumor metastasis because of their capacity to coordinately repress numerous target genes, thereby potentially enabling their intervention at multiple steps of the invasion-metastasis cascade. We identify a microRNA exemplifying these attributes, miR-31, whose expression correlates inversely with metastasis in human breast cancer patients. Overexpression of ...
TGF-β1-induced epithelial-mesenchymal transition (EMT) has been proved to be associated with metastasis of breast cancer cells. We attempted to detect a novel mechanism that microRNAs mediated the TGF-β1-induced EMT in the process of breast cancer metastasis. Here we reported that the expression of miR-23a was higher in breast cancer cells with high metastasis ability and patients with lymph no...
