Expression of TRPC1 and SBEM protein in breast cancer tissue and its relationship with clinicopathological features and prognosis of patients.

ABSTRACT: This study investigated the relationship of the expression of transient receptor potential channel 1 (TRPC1), small breast epithelial mucin (SBEM) in breast cancer tissues with clinical pathological features and prognosis of patients. Altogether 50 patients with breast cancer who were treated in Weifang People's hospital from April 2017 to November 2018 were selected, and the mRNA and protein differences of TRPC1 and SBEM in breast cancer patients and normal breast cancer tissues were detected by qRT-PCR and Western blot. Spearman test was used for correlation analysis. Logistic univariate and multivariate analysis were performed on the risk factors related to breast cancer metastasis in breast cancer patients. The expression of TRPC1 and SBEM in breast cancer tissues was significantly higher than that in normal breast tissues (P<0.001). The mRNA expression of TRPC1, SBEM and protein was not related to age, tumor size and tissue grade of breast cancer patients, but related to TNM stage, clinical stage and lymph node metastasis (P<0.001). The relative expression of TRPC1 was positively correlated with clinical stage of breast cancer (r=0.992, P<0.001). The relative expression of SBEM was positively correlated with the clinical stage of breast cancer (r=0.853, P<0.001). The relative expression of TRPC1 was positively correlated with TNM staging of breast cancer (r=0.860, P<0.001). The relative expression of SBEM was positively correlated with TNM staging of breast cancer (r=0.880, P<0.001). Multivariate conditional Logistic regression analysis showed that TNM staging, TRPC1, SBEM were independent risk factors for malignant breast cancer metastasis. On the contrary, expression of TRPC1 and SBEM in breast cancer tissues was up-regulated. TRPC1 and SBEM may be involved in the process of breast cancer occurrence, development and metastasis, and can be used as potential tissue biomarkers in diagnosis of breast cancer metastasis and disease assessment.

Project description:Expression of miR-129-5p and miR-433 was detected in breast cancer to explore the relationship with clinicopathological features of breast cancer. Seventy-eight patients with breast cancer diagnosed in Zhengzhou Central Hospital Affiliated to Zhengzhou University (Zhengzhou, China) from February 2016 to September 2017 were collected and enrolled into the research group. Additionally, 72 healthy people who underwent physical examination during the same period were selected as the control group. The expression levels of miR-129-5p and miR-433 in peripheral blood of the two groups were detected by fluorescence quantitative PCR (RT-PCR). The relationship between the expression of miR-129-5p, miR-433 and clinicopathological features, clinical stages of breast cancer, and the degree of differentiation were analyzed. Expression of miR-129-5p and miR-433 in the research group was significantly lower than that in the control group (P<0.05). Expression of miR-129-5p in the blood of breast cancer patients was correlated with tumor size, differentiation degree, lymph node metastasis, depth of invasion and clinical stages (P<0.05). Expression level of miR-433 was correlated with the degree of differentiation, lymph node metastasis, depth of invasion and clinical stages (P<0.05). miR-129-5p and miR-433 were positively correlated with differentiation degree (r=0.8507, r=0.7522; P<0.05), and negatively correlated with clinical stages (r=-0.6595, -0.8947; P<0.05). The sensitivity and area under curve (AUC) were higher in joint detection (87.5 and 0.95% respectively), compared with those in single detection. Patients were separated into high and low expression groups according to the median values of miR-129-5p and miR-433. The one-year survival rate of breast cancer patients was analyzed. Patients in the low expression groups had lower survival rates than patients in the high expression groups (P<0.05). In conclusion, the expression of miR-129-5p and miR-433 in peripheral blood of breast cancer patients is lower than that of healthy people, and the expression level is closely related to clinical stages and differentiation degree, which is expected to provide reference value for judging the state of breast cancer patients. The combined detection of miR-129-5p and miR-433 is of great significance in the diagnosis and treatment of breast cancer.
