Abstract

An increased level of chitinase 3 like 1 protein (CHI3L1) expression is observed in patients with cancer and may have potential prognostic value. The aim of this study was to evaluate the role of CHI3L1 in angiogenesis in invasive ductal breast carcinoma (IDC) (n=110). Immunohistochemistry was used to assess the expression of CHI3L1, CD31, CD34, vascular endothelial growth factor (VEGFA, VEGFC and VEGFD). Real-time polymerase chain reaction and western blot were used to determine the level of CHI3L1 mRNA and protein. Immunohistochemistry demonstrated positive correlation between CHI3L1 expression and angiogenesis markers: CD31 (r=0.34, p=0.0003), CD34 (r=0.24, p=0.012), VEGFD (r=0.24, p=0.013). Higher CHI3L1 expression in estrogen receptor-negative (p=0.041) and progesterone receptor-negative (p=0.014) cancer was observed. Higher CHI3L1 expression was reported in cancer tissues in comparison to non-malignant breast lesions. These results suggest a potential role of CHI3L1 in angiogenesis in IDC and may suggest its involvement in cancer progression.
