Abstract
Objective To investigate the expression of Scinderin (SCIN myoprotein) in breast cancer tissues and adjacent tissues, and to explore the relationship between the expression of Scinderin and different molecular subtypes of breast cancer as well as the clinical factors. Methods Immunohistochemical staining method was used to detect the expression of SCIN in 120 cases of breast carcinoma and 30 adjacent tissues. The relation between SCIN expression in breast cancer tissue and molecular subtypes, pathologic stage, age, tumor size, lymph node metastasis was analyzed. Results SCIN expression level in breast cancer tissue was lower than in the tissues adjacent to carcinoma (6.06±3.32 vs 7.77±3.32, P 0.05) . Conclusions The expression of SCIN in breast cancer tissues was lower than in the adjacent tissues. It is associated with breast cancer molecular subtypes. SCIN could become the protein markers of breast cancer molecular targeted therapy. Key words: Scinderin; Breast cancer; Molecular subtypes
