Metformin, a widely used antidiabetic drug, exhibits anticancer effects which are mediated by the phosphatidylinositol 3-kinase (PI3K)/serine/threonine kinase (AKT) signaling pathway. However, its use in anticancer therapy combined with other natural products remains unclear. Flavone as the core structure of flavonoids has been demonstrated to induce cell apoptosis without causing serious side effect. Murine double minute X (MDMX) inhibits tumor suppressor gene p53 whose function is associated with the PI3K/AKT pathway...

Breast cancer suppressor candidate-1 (BCSC-1) is a candidate tumor suppressor gene that was identified recently. Decreased levels of BCSC-1 have been detected in a variety of cancer types in previous studies. Matrix metalloproteinase (MMP)-14 is a membrane-type MMP that plays an important role in tumor progression and prognosis. Previous research has indicated that MMP-14 is highly expressed in different cancer types and promotes tumor invasion or metastasis by remodeling the extracellular matrix. However, there have been few reports on BCSC-1 and MMP-14 in human breast cancer in recent years...

p60 is a subunit of katanin involved in microtubule-severing. Previous studies of p60 were primarily focused on microtubule regulation and cell cycle regulation. More recent research has demonstrated that katanin p60 possesses a function in prostate cancer bone metastasis; however, its role in breast cancer bone metastasis remains unclear. In the present study, immunohistochemistry was used to analyze the expression of katanin p60 in primary and bone metastatic breast cancer. The role of up- and downregulated katanin p60 was investigated using cell proliferation, and migration experiments...

Tumor characteristics are used today to evaluate the possibility of mutation and to target mutation screening in families with high risk of breast and/or ovarian cancer. We studied the breast tumor profile associated to the c.3481_3491del11 French founder effect mutation on the BRCA1 gene to an attempt to identify any particularity or difference when comparing it to that related to other BRCA1 mutations. Within the population who were referred to our oncogenetic clinic at the Lorraine Oncology Institute in France and who underwent genetic testing between 1994 and 2012, we identified 404 women carrying a BRCA1 mutation...

Resveratrol (RES) is well known natural polyphenol with proven antioxidant, antiinflammatory and anticarcinogenic properties. Since mode of application may be important for cancer-preventive effects of RES, the aim of this study was to evaluate a possible delay in the initiation and progression of chemically induced mammary carcinogenesis in female Sprague-Dawley rats after the nocturnal administration of RES. Application of a high dose of RES (100 mg/kg body weight), starting 2 weeks before the first N-methyl-N-nitrosourea dose (NMU) (50 mg/kg body weight), reduced tumor incidence and markedly prolonged latency period (P < 0...

BACKGROUND CONTEXT: The current standard of care for prediction of survival of cancer staging is based on TNM staging. However, for patients with spinal metastasis, who all have identical stage IV disease, identifying accurate prognostic markers of survival would allow better treatment stratification between more aggressive treatment strategies or palliation. Analytic morphometrics enables physicians to quantify patient frailty by measuring lean muscle mass. Morphometrics also predicts survival in patients with lung cancer metastases to the spine...

The incidence of breast cancer increases with age until menopause, and breast cancer is more aggressive in younger women. The existence of epidemiological links between breast cancer and aging indicates that both processes share some common mechanisms of development. Oxidative stress is associated with both cancer susceptibility and aging. Here we observed that ERBB2-positive breast cancer, which developed in genetically heterogeneous ERBB2-positive transgenic mice generated by a backcross, is more aggressive in chronologically younger than in older mice (differentiated by the median survival of the cohort that was 79 weeks), similar to what occurs in humans...

Breast cancer arises as the most frequent malignancy, and causes the majority of cancer death among females worldwide. Src is a tyrosine kinase identified as the product of the proto-oncogene and is supposed to promote cancer development and metastasis. Src inhibitors are recently developed and have shown efficacy in breast cancer. Increasing evidences suggest that aberrant expression of miRNAs is involved in cancer development and drug resistance. Identifying miRNAs associated with drug resistance may enhance the sensitivity of targeted therapies, including Src inhibitors...
