Abstract GSK-3 is a versatile protein kinase participating in many reactions. Currently, there is insufficient understanding of its influence on breast cancer (BC). In order to explore its influence on migration and invasion in BC, we investigated its expression in BC cell lines using qRT-PCR and Western blot (WB). Immunohistochemistry (IHC) was used to examine the potential of GSK-3 to predict clinical outcome in BC patients. GSK-3 knockdown was achieved using an shRNA plasmid vector in T47D cells. Our research explored the biological reactions and downstream pathways involved. We found excessive GSK-3 expression in BC tissues,… More >

Abstract The collective cell migration behavior on a substrate was studied using RKPM meshfree method. The cells were modeled as nematic liquid crystal with hyperelastic cell nucleus. The cell-substrate and cell-cell interactions were modeled by coarse-grained potential forces. Through this study, the pulling and pushing phenomenon during collective cell migration process was observed and it was found that the individual cell mobility significantly influenced the collective cell migratory behavior. More self-propelled cells are in the system along the same direction, the faster the collective group migrates toward coordinated direction. The parametric study on cell-cell adhesion strength More >

Abstract Hepatocellular carcinoma (HCC) is one of the most prevalent and lethal malignancies worldwide. Increased matrix stiffness of extracellular matrix (ECM) is commonly associated with HCC. During tumour formation and expansion, increasing glucose metabolism is necessary for unrestricted growth of tumour cells. Yet, the correlation between matrix stiffness and glucose metabolism in the development of HCC remains unknown. In this study, we aim to investigate the effect of matrix stiffness on glucose metabolism and migration of MHCC97L and HepG2 hepatoma cells, and explore the mechanotransduction involved in this process. Polyacrylamide hydrogels with stiffness gradients of 6,… More >

Abstract This study was aimed to investigate the function and mechanism of microRNA-200c (miR-200c) in the progression of non-small cell lung cancer (NSCLC). A total of 76 patients diagnosed as having NSCLC were enrolled in this study. The expression level of miR-200c in NSCLC tissues and cell lines was investigated using the quantitative real-time polymerase chain reaction (RT-qPCR) method. We found that the expression of miR- 200c was significantly reduced in NSCLC tissues and cell lines compared with normal lung tissues and the human bronchial epithelial cell line. Overexpression of miR-200c using the miR-200c mimic significantly… More >

Abstract Tbx3, a member of the T-box family of transcription factors, contributes directly to tumor formation, migration, and invasion. However, the role of Tbx3 in the metastasis of HCC remains unclear. In the present study, Tbx3 expression was detected in HCC tissues and cells by Western blot, and Tbx3 expression was regulated by use of siRNAs or lentivirus-mediated vectors. Here we found that Tbx3 protein expression increased in HCC tissues and cell lines. Tbx3 expression was positively associated with multiple tumor nodes, venous infiltration, and advanced TNM tumor stage. Survival analysis demonstrated that Tbx3 expression was… More >

Abstract This study aimed to investigate the role of miR-144-3p in pancreatic cancer (PC) carcinogenesis and to explore the mechanism of its function in PC. miR-144-3p was downregulated in PC tissues and cells. miR-144-3p overexpression significantly inhibited PC cell proliferation, migration, and invasion. FosB proto-oncogene, AP-1 transcription factor subunit (FOSB) was a target gene of miR-144-3p. miR-144-3p could repress PC cell proliferation, migration, and invasion by inhibiting the expression of FOSB. In conclusion, miR-144-3p plays an important role in PC cell proliferation, migration, and invasion by targeting FOSB. miR-144-3p may provide a new target for the More >

Abstract This study intended to investigate the effects of miR-3188 on breast cancer and to reveal the possible molecular mechanisms. miR-3188 was upregulated and TUSC5 was downregulated in breast cancer tissues and MCF-7 cells compared to normal tissue and MCF-10 cells. After MCF-7 cells were transfected with miR-3188 inhibitor, cell proliferation and migration were inhibited, whereas apoptosis was promoted. Luciferase reporter assay suggested that TUSC5 was a target gene of miR-3188. In addition, miR-3188 overexpression increased the p-p38 expression, while miR-3188 suppression decreased the p-p38 expression significantly. miR-3188 regulated breast cancer progression via the p38 MAPK More >

Abstract Cell migration is the cornerstone of many biological phenomena such as cancer metastasis, immune response or organogenesis. Adhesion-based motility is the most renown and examined motility mode, but in an adhesion-free confined environment or simply to achieve a higher migration speed, cells can adopt a very interesting bleb-based migration mode called “chimneying”. This mode rests on the sharp synchronization between the active contraction of the cells uropod and the passive friction force between the cell and the confining surface. In this paper, we propose a one dimensional poroelastic model of chimneying which considers the active… More >

Abstract Our study aimed to investigate whether microRNA-449 (miR-449) plays a key role in regulating the migration and invasion of breast cancer cells via targeting tumor protein D52 (TPD52). The results of the qRT-PCR and Western blotting showed that, in comparison with normal breast tissues and cells, miR-449 was significantly downregulated in breast cancer tissues and cells, while TPD52 was markedly upregulated. After transfection with an miR-449 inhibitor, suppression of miR-449 significantly promoted cell migration and invasion. Also, when miR-449 was overexpressed by transfection with miR-449 mimics, E-cadherin expression significantly increased, and the expression of N-cadherin More >
