Background: The purpose of the study was to analyze relationship between caspase-like (CL) and chymotrypsin-like (ChTL) activities proteasomes 5-year overall metastasis-free survival rates in patients with luminal breast cancer.

The development of breast cancer metastasis is accompanied by dynamic transcriptome changes and dramatic alterations in nuclear and chromatin structure. The basis of these changes is incompletely understood. The DNA methylome of primary breast cancers contribute to transcriptomic heterogeneity and different metastatic behavior. Therefore we sought to characterize methylome remodeling during reg...

PURPOSE It is well established that breast cancer metastasis suppressor 1 (BRMS1) suppresses metastasis of breast cancer in animal models without affecting the growth of the primary tumor. It has also been shown to suppress the metastasis of tumors derived from breast and melanoma cell lines. However, its clinical importance for breast cancer patients remains undetermined. This prompted us to i...

Bone is the most common target organ of metastasis of breast cancers. This produces considerable morbidity due to skeletal-related events, and severely reduces the quality of life. Increased osteoclast activity is implicated in breast cancer outgrowth in the bone microenvironment. Our previous observation of an anti-osteoclastic activity of hypericin, a natural plant compound, led us to investi...

Breast skin and parenchyma are metastatic sites for various tumours. Metastasis to the breast is rare, but it must be considered in the differential diagnosis of a breast mass. Melanoma is among the most commonly reported metastatic tumours of the breast. With the increasing incidence of melanoma, this complication is being encountered with greater frequency. Melanoma has different manifestatio...

Liver metastasis from breast cancer usually results in the development of systemic metastasis. We report a breast cancer patient with an early isolated liver recurrence who survived more than 7 years with no recurrence. She was treated with aggressive HER2-directed chemotherapy and hepatic metastasectomy. Local hepatectomy with effective medical oncological therapy with curative intent is worth...

Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass...

PURPOSE Breast cancer is a multifactorial disease and identification of the genes and proteins regulating breast carcinogenesis is critical in exploring novel targeted therapies. The aim of this study was to investigate the role CETN1 in breast cancer growth and metastasis. METHODS CETN1 expression levels were measured in breast tissue samples by immunohistochemistry (IHC). We selected high C...

breast cancer is the most common cause of cancer-related death in female, after lung cancer. angiogenesis is essential for tumor growth and metastasis; therefore, antiangiogenesis strategies for treatment of cancer are currently an issue of interest. the role of vascular endothelial growth factor that assumed to be most potent angiogenesis factor is ambiguous in breast cancer. this study descri...
