Objective · To explore the inhibitive effect of silencing the CD147 gene on the proliferation of triple negative breast cancer cells and relevant mechanisms. Methods · Normal human mammary epithelial cell line HMEC and three triple negative breast cancer cell lines MDA-MB-231, HCC70 and T4-2 were cultured in vitro. mRNA and protein expressions in cells were measured using realtime-PCR and Western blotting, respectively. A siRNA sequence targeting the coding region of human CD147 gene was designed and used to construct a recombinant lentivirus Lv-shRNA-CD147, which was used to infect the three breast cancer cell lines. The negative control group (Lv-NC infected group) and the noninfected cell control group (cell control group) were simultaneously used. The effects of silencing the CD147 gene were measured with real-time PCR and Western blotting. The proliferation and migration of cells were measured with MTT and Transwell assay, respectively. HCC70 cells were collected 72 h after viral infection and proteins related to proliferation, migration and apoptosis of cells (β-catenin, MMP2, MMP9, and Bax) were measured with Western blotting. Results · mRNA and protein expressions of CD147 were significantly higher in three breast cancer cell lines than in HMEC (P<0.01). The Lv-shRNA-CD147 infected group had lower mRNA and protein expressions of CD147, cell proliferation, and cell migration as compared with the Lv-NC infected group and the cell control group,the differences were statistically significant (P<0.01). The Lv-shRNA-CD147 infected group had lower expressions of β-catenin, MMP2, and MMP9, and higher Bax expression in HCC70 cells 72h after viral infection as compared with the Lv-NC infected group and the cell control group, the differences were statistically significant (P<0.01). Conclusion · Silencing the CD147 gene can inhibit the proliferation and migration of triple negative breast cancer cells.

An endogenous element-label plus exogenous element-tag strategy was proposed for inductively coupled plasma mass spectrometry ( ICP-MS) to screen and discriminate a family of ultratrace but biological important biomolecules. The feasibility of this novel idea has been demonstrated when setting seleno ( SeCys) and Se-containing ( SeMet) proteins ( peptides) as an example. Se-label naturally occurring in the biomole-cules acts an identifier for picking them up out of large amount of various coexisting proteins ( peptides) , and CH3 Hg-tag that can bind to SeCys but not SeMet fulfills the task of discriminating seleno and Se-containing ones based on the Se and Hg signals on ICP-MS. After confirmed using SeCys and GPx1, the Se-Hg dual-element labeling strategy together with ICP-MS was applied to screen and discriminate seleno and Se-contai-ning proteins ( peptides) in the water-soluble extracts of Se-enriched yeast, and seven selenoproteins ( pep-tides) were detected with both 202 Hg and 82 Se signals out of fifteen Se-containing species using RPLC/ICP-MS, providing valuable information for further identification using a high-resolution structure-selective mass spectrometer. This endogenous element-label plus exogenous element-tag dual-element approach implies that ICP-MS is not only able to quantify targeted proteins ( peptides) but also helpful to recognize targeted proteins during a discovery-based proteomic study.

This study was aimed to observe effect of combined therapy of acupuncture, tapping and auricular needling on fatty-insulin endocrine axis in obesity complicated with hyperlipidaemia patients withyin-deficiency and blood-stasis pattern. A total of 108 patients with obesity complicated with hyperlipidaemia ofyin-deficiency and blood-stasis pattern were randomly divided into the treatment group of combined therapy of acupuncture, tapping and auricular needling, and the acupuncture and tapping group, with 54 cases in each group. The comparison was made to 52 patients in the normal group. Observations were made on changes of fatty-insulin endocrine axis index, lipid index, obesity index, vegetative nerve function index (Y value) and clinical weight-reducing and lipid-reducing effect. The results showed that the pretreatment obesity index, fasting insulin (FINS), fasting plasma glucose (FPG), insulin resistance index (Homa-IR), fasting leptin (FLP), triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL-C) and Y value of patients in both groups were significantly higher than those of the normal group (P < 0.01). However, the high density lipoprotein (HDL-C) and insulin sensitivity index (ISI) were significantly lower than those of the normal group (P < 0.01). After treatment, both groups received satisfied effects on weight-reducing and lipid-reducing. The fatty-insulin endocrine axis indexes (FINS, FPG, Homa-IR and FLP) were significantly reduced (P < 0.05); and ISI was significantly increased (P < 0.05). The combined therapy of acupuncture, tapping and auricular needling had better regulation effects on the fatty-insulin endocrine axis level, lipid level and vegetative nerve function level compared with the acupuncture and tapping group (P < 0.05). It was concluded that patients with obesity complicated with hyperlipidaemia ofyin-deficiency and blood-stasis pattern had dysfunction of the fatty-insulin endocrine axis. The combined therapy of acupuncture, tapping and auricular needling, or the therapy of acupuncture and tapping had good regulation effect. However, the combined therapy of acupuncture, tapping and auricular needling had more significant therapeutic effect.
