Project description:This study provides insights into the efficacy of beta-blockers as breast cancer therapeutics.Cell line models of basal-type and estrogen receptor-positive breast cancer were profiled for basal levels of adrenoceptor gene/protein expression, and ADRβ2-mediated cell behaviour including migration, invasion, adhesion, and proliferation in response to adrenoceptor agonist/antagonist treatment. Protein profiling and histology identified response biomarkers and drug targets. Protein profiling revealed the upregulation of the pro-metastatic gene LYPD3 in norepinephrine treated MDA MB 468 cells. Histology confirmed selective LYPD3 expression in clinical primary and metastatic breast tumours. These findings demonstrate that basal-type cancer models show a more aggressive ADRβ2-activated phenotype in the resting and stimulated state, which is attenuated by ADRβ2 inhibition, and explain some of the previous studies that have cast doubt on the value of beta-blocker therapy in breast cancer. These findings suggest that propranolol should be clinically evaluated in patients with basal-type tumours expressing high levels of ADRβ2 and LYPD3.

Project description:The SLC22A18 gene, which encodes an orphan transporter, is located at the 11p15.5 imprinted region, an important tumor-suppressor gene region. However, the role of SLC22A18 in tumor suppression remains unclear. Here, we investigated the involvement of SLC22A18 in cell growth, invasion and drug resistance of MCF7 human breast cancer cell line. Western blot analysis indicated that SLC22A18 is predominantly expressed at intracellular organelle membranes. Quantitative proteomics showed that knockdown of SLC22A18 significantly altered the expression of 578 (31.0%) out of 1867 proteins identified, including proteins related to malignancy and poor prognosis of breast cancer.

Project description:Breast cancer remains a leading cause of cancer-related death, for which the majority of deaths result from metastases. Von Willebrand factor C and EGF domain (VWCE) is a member of the Von Willebrand factor (VWF) gene family; however, its function, regulatory mechanism, and clinical value in breast cancer remain unclear. In the present study, we sought to elucidate the role of VWCE in breast cancer metastasis. We examined the expression of VWCE in breast cancer tissues and normal control tissues of 50 breast cancer patients. We found that VWCE expression was downregulated in breast cancer cells and tissues compared to normal breast epithelial cells or the adjacent normal tissues. To explore the role of VWCE in human breast cancer development, we introduced a VWCE-overexpressing or control lentiviral vector into the breast cancer MDA-MB-453 and MDA-MB-231 lines in vitro. The overexpression of VWCE inhibited the proliferation, migration, invasion, and chemoresistance of the breast cancer cell lines. More import

Abstract
A type of cancer which originates from the breast tissue is referred to as breast cancer. Globally, it is the most common cause of death in women. Treatments such as radiotherapy, chemotherapy, hormone therapy, immunotherapy, and gene therapy are the main strategies in the fight against breast cancer. The present study aims at investigating the effects of the combined radiotherapy and chemotherapy as a way to treat breast cancer, and different treatment approaches are incorporated into the model. Also, the model is fitted to data on patients with breast cancer in Tanzania. We determine new treatment strategies, and finally, we show that when sufficient amount of chemotherapy and radiotherapy with a low decay rate is used, the drug will be significantly more effective in combating the disease while health cells remain above the threshold.
