Mechanisms of Chemoresistance in Breast Cancer Cells

Ubc9 expression predicts chemoresistance in breast cancer

Ubiquitin-conjugating enzyme 9 (Ubc9), the sole conjugating enzyme for sumoylation, regulates protein function and plays an important role in tumorigenesis. Whether Ubc9 is involved in the chemoresistance of breast cancer remains unknown. In this study, we aimed to evaluate the contribution of Ubc9 in the chemoresistance of breast cancer. Immunohistochemistry (IHC) was used to examine the expre...

Breast cancer chemoresistance: emerging importance of cancer stem cells.

Cancer stem cells (CSCs) have recently been documented in solid tumours. Evidence has suggested that CSCs are involved in carcinogenesis, tumour invasion and metastases, and resistance to various forms of therapies, including chemotherapy. Breast CSCs are characterised by the expression of CD44 but lack of CD24 (CD44(+)/CD24(-) cells). The mechanisms involved in chemoresistance of breast CSCs a...

Breast Cancer Associated with Dermatomyositis

Dermatomyositis (DM) is a rare idiopathic inflammatory myopathy with characteristic skin lesions. Case series have shown an association between dermatomyositis and malignancy. Malignancy has been found in 15-25% of the adult patients with dermatomyositis. A 50-year-old new case of breast cancer, was admitted with muscle weakness and inability to walk. Physical examination revealed fever, perior...

Change of Hemoglobin Concentration with nano particles can predict breast cancer using near infrared source?

Introduction: Early detection and treatment of breast cancer may be helping to save the lives of patients. Many new techniques have been urban to detect breast cancer. One of them is the use of nano-particles for accuracy and early diagnosis after photo transfer. In this study, rod gold nano particles was used according their ability to change light source transfer intensity. ...
