Purpose:
The purpose of the current study was to explore the functions and potential mechanism of miR-451a in breast cancer (BC).
Methods:
Quantitative reverse transcription real-time polymerase chain reaction was used to analyze the expression of miR-451a in human normal mammary cells (MCF-10A) and BC cells. Colony formation assay, terminal-deoxynucleoitidyl transferase mediated nick end labeling assay and transwell assays were conducted to validate the effect of miR-451a on proliferation, apoptosis, migration and invasion of BC cells, respectively. RNA pull-down, RNA immunoprecipitation and luciferase reporter assays were applied to investigate the upstream and downstream mechanisms of miR-451a in BC cells.
Results:
MiR-451a was expressed at a low level in BC cells. Overexpression of miR-451a repressed BC cells proliferation, migration and invasion. Moreover, long non-coding RNA AC092127.1 acted as a sponge of miR-451a to enhance the expression level of AE binding protein 2 (AEBP2) that was demonstrated to be the target gene of miR-451a in BC cells. Finally, rescue experiments validated that miR-451a and AEBP2 involved in AC092127.1-mediated BC cell growth, migration and invasion.
Conclusion
In a word, AC092127.1/miR-451a/AEBP2 axis contributes to BC cell growth, migration and invasion. Our results may help to find novel potential targets for BC treatment.

Objective To investigate the effect of hyperthermia on the expression of E6 and E7 genes of human papillomavirus (HPV) type 6 and 11 in HPV-infected human skin. Methods Tissue samples were obtained from the lesions of condyloma accuminatum (CA) in 6 patients after informed consent. Each sample was divided into 4 parts: one was embedded and directly stored at -80 ℃; the other 3 parts were placed in culture medium and the surface of the samples was irradiated for 30 minutes with a thermotherapy apparatus at 37℃, 42 ℃, 45 ℃, respectively, then the samples were taken out and stored at -80 ℃. RNA was extracted from the specimens, real time quantitative PCR (qPCR) was performed to detect the expression of E6 and E7 genes of HPV-6 and -11. Results Of the 6 patients, 2 were infected with HPV-6 and -11 respectively, 4 with both HPV-6 and HPV-11. The expression of E6 and E7 mRNA decreased with the increase in irradiation temperature. The relative mRNA expression levels at 37 ℃, 42 ℃ and 45 ℃ were 1.00 ± 0.00, 0.61 ± 0.17, 0.27 ± 0.15, respectively, for HPV-6 E6 gene, 1.00 ± 0.00, 0.56 ± 0.21, 0.16 ± 0.11 respectively, for HPV-6 E7 gene, 1.00 ± 0.00, 0.60 ± 0.22, 0.16 ± 0.08, respectively, for HPV-I1 E6 gene, 1.00 ± 0.00, 0.55 ± 0.15, 0.24 ± 0.06, respectively, for HPV-11 E7 gene; statistical difference was noted among them between the specimens irradiated at different temperature (all P < 0.01). Conclusion Hyperthermia can remarkably suppress the expression of HPV-6/I 1 E6 and E7 genes, which may be a possible mechanism under the regression of warts induced by local hyperthermia.

Objective To observe the effect of costimulatory molecule B7-1 on cytoskeleton rearrangement in mouse podocytes induced by angiotensin Ⅱ (Ang Ⅱ),and to study the underlying molecular mechanism of B7-1 in the pathological changes of podocytes.Methods All cultivation of conditionally immortalized mouse podocytes (MPC) in vitro were divided into the following groups:normal control group,CTLA-4 group,Ang Ⅱ group (10-6 mmol/L 12 h,24 h;10-8 mmol/L 12 h,24 h) and CTLA-4 with Ang Ⅱ group.Transfect B7-1 RNA interference fragment (siRNA) to the mature podocytes,and then restimulated by Ang Ⅱ (10-6 mmol/L 12 h),the change of podocyte cytoskeleton after Ang Ⅱ stimulation were observed.The expression of B7-1 in each group was assayed by flow cytometry and Western blotting.The nephrin and p-nephrin protein levels in the four groups were also analyzed by Western blotting.At the same time,the podocyte cytoskeleton distribution as indicated by F-actin was observed by fluorescence microscopy.Results Flow cytometry and Western blotting showed that B7-1 was not expressed in the normal control group.Ang Ⅱ showed a concentration and time dependent induction of B7-1 expression in mouse podocytes (P < 0.05).Western blotting indicated that Ang Ⅱ induced B7-1 protein expression (P < 0.05).Expression of nephrin and p-nephrin was significantly down-regulated by Ang Ⅱ (P < 0.05).Compared with the normal control group,the expression of podocyte protein nephrin and p-nephrin in Ang Ⅱ stimulation group was significantly reduced (P < 0.05).Using FITC phalloidin fluorescence staining showed that CTLA-4+Ang Ⅱ stimulation group cytoskeleton rearrangement was improved significantly and F-actin recombinant score (mCFS) decreased compared with Ang Ⅱ group (P < 0.05),suggesting that Ang Ⅱ led to the disorder of the podocytes cytoskeleton and the destruction of the cytoskeleton of podocytes by Ang Ⅱ could be improved after B7-1 blocking.Compared with the Ang Ⅱ stimulation,transfection of B7-1 siRNA + Ang Ⅱ stimulation group improved F-actin cytoskeletal rearrangement,and mCFS also decreased significantly (P < 0.05),suggesting that transfection of B7-1 siRNA might improve the damage of Ang Ⅱ on podocytes cytoskeleton.Conclusions B7-1 participates in the process of cytoskeleton reconstruction and plays an important role in the pathological changes of podocytes.
