    MicroRNA-548m Suppresses Cell Migration and Invasion by Targeting Aryl Hydrocarbon Receptor in Breast Cancer Cells

    WM Farhan Syafiq B. WM Nor*†, Ivy Chung‡§, Nur Akmarina B. M. Said

    Oncology Research, Vol.28, No.6, pp. 615-629, 2020, DOI:10.3727/096504020X16037933185170

    Abstract Breast cancer is the most commonly diagnosed cancer among women and one of the leading causes of cancer mortality worldwide, in which the most severe form happens when it metastasizes to other regions of the body. Metastasis is responsible for most treatment failures in advanced breast cancer. Epithelial–mesenchymal transition (EMT) plays a significant role in promoting metastatic processes in breast cancer. MicroRNAs (miRNAs) are highly conserved endogenous short noncoding RNAs that play a role in regulating a broad range of biological processes, including cancer initiation and development, by functioning as tumor promoters or tumor suppressors.… More >

    Dancing to a somewhat different rhythm: Cell migration along the natural basement membrane

    SHELDON R. GORDON*

    BIOCELL, Vol.46, No.9, pp. 2059-2063, 2022, DOI:10.32604/biocell.2022.019873

    Abstract Much of our understanding of the events which underlie cell migration has been derived from studies of cells in tissue culture. One of the components that mediates this process is the dynamic actin-based microfilament system that can reorganize itself into so-called stress fibers that are considered essential components for cell motility. In contrast, relatively few studies have investigated cell movement along an extracellular matrix (ECM) which is known to influence both cellular organization and behavior. This opinion/viewpoint article briefly reviews cell migration during corneal endothelial wound repair along the tissue’s natural basement membrane, Descemet’s membrane. More >

    Computational Investigation of Cell Migration Behavior in a Confluent Epithelial Monolayer

    Jie Bai, Xiaowei Zeng*

    CMES-Computer Modeling in Engineering & Sciences, Vol.131, No.2, pp. 551-565, 2022, DOI:10.32604/cmes.2022.019376

    Abstract Cell migration plays a significant role in many biological activities, yet the physical mechanisms of cell migration are still not well understood. In this study, a continuum physics-based epithelial monolayer model including the intercellular interaction was employed to study the cell migration behavior in a confluent epithelial monolayer at constant cell density. The epithelial cell was modeled as isotropic elastic material. Through finite element simulation, the results revealed that the motile cell was subjected to higher stress than the other jammed cells during the migration process. Cell stiffness was implied to play a significant role More >

    LINC complex independent perinuclear actin organization and cell migration

    ANDREA FRACCHIA1,2, GABI GERLITZ1,*

    BIOCELL, Vol.46, No.4, pp. 931-935, 2022, DOI:10.32604/biocell.2022.018179

    Abstract The link of the metazoan nucleus to the actin cytoskeleton is highly important for actin polymerization and migration of multiple cell types as well as for mechanotransduction and even affects the cellular transcriptome. Several mechanisms of organization of actin filaments next to the nuclear envelope have been identified. Among these mechanisms the most studied one is the Linker of nucleoskeleton and cytoskeleton (LINC) complex-dependent perinuclear actin organization. However, recently additional mechanisms have been identified: an Actin-related protein-2/3 (Arp2/3)-dependent perinuclear actin polymerization during migration of dendritic cells and a perinuclear actin rim that is formed in More >

    BIOCELL, Vol.45, No.4, pp. 911-921, 2021, DOI:10.32604/biocell.2021.010119

    Abstract Distal gastric cancer (DGC) is a subgroup of gastric cancer (GC), which has different molecular characteristics from proximal gastric cancer (PGC). These differences result in different overall survival (OS) rates; however, data pertaining to the survival rate in PGC or DGC are contradictory. This suggests that the location of GC is not the unique cause of the different survival rates, while the molecular characteristics might be more important factors determining the prognosis of DGC. Therefore, the aim of this study was to discover key prognostic factors in DGC using bioinformatic methods and to explore the… More >

    Computational Study of Collective Cell Migration By Meshfree Method

    Jie Bai1,#, Liqiang Lin1,#, Xiaowei Zeng 1,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.121, No.3, pp. 787-800, 2019, DOI:10.32604/cmes.2019.07159

    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 >

    Brief Note: CD44 is involved in CXCL-12 induced acute myeloid leukemia HL-60 cell polarity

    LIPING ZHOU*, XIAOLIN GUO, JING BA, LIANSHUANG ZHA

    BIOCELL, Vol.34, No.2, pp. 91-94, 2010, DOI:10.32604/biocell.2010.34.091

    Abstract CXCL-12 and its receptor CXCR4 participate in breast cancer and melanoma cell metastasis to bone and lymphoid nodes. CD44, as a receptor for hyaluronic acid, is involved in lymphocyte recirculation, homing, adhesion and migration. But the role of CD44 in CXCL-12 induced leukemia cell migration still remains unclear. The present study showed that CXCL-12 stimulation induced the rapid internalization of CXCR4 and facilitated the formation of lamellipodia and uropod in acute leukemia cell line HL-60. CXCL12 also induced CD44 translocation into the uropod, while CD44 remained evenly distributed on the untreated cell membranes. Results suggest More >

    Apigenin inhibits cell migration through MAPK pathways in human bladder smooth muscle cells

    QINGXIN LIU , XIANGGUI CHEN, GUOLIN YANG1 , XUEWEN MIN3 , AND MAOXIAN DENG1,*

    BIOCELL, Vol.35, No.3, pp. 71-80, 2011, DOI:10.32604/biocell.2011.35.071

    Abstract Apigenin, a nonmutagenic flavonoid, has been shown to possess free radical scavenging activities, anticarcinogenic properties, antioxidant and anti-inflammatory effects. Recently, apigenin was reported to cause gastric relaxation in murine. To assess possible effects of apigenin on migration of bladder smooth muscle (SM) cell, we isolated SM cells from peri-cancer tissue of human bladder and established a cell model that was capable to overexpress transiently MEKK1 (MEK kinase 1). Results showed that overexpression of active human MEKK1 by adenoviruses infection induced migration of human bladder smooth muscle (hBSM) cells and phosphorylation of MAPKs, ERK, JNK and More >

    ABSTRACT

    Matrix Stiffness Promotes Hepatoma Cell Glycolysis and Migration Through YAP-Mediated Mechanotransduction

    Qiuping Liu1, Guanbin Song1,*

    Molecular & Cellular Biomechanics, Vol.16, Suppl.2, pp. 127-127, 2019, DOI:10.32604/mcb.2019.07105

    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 >

    A Coupled Friction-Poroelasticity Model of Chimneying Shows that Confined Cells Can Mechanically Migrate Without Adhesions

    Solenne Mondésert-Deveraux1, *, Rachele Allena2, Denis Aubry1

    Molecular & Cellular Biomechanics, Vol.15, No.3, pp. 155-176, 2018, DOI:10.3970/mcb.2018.03053

    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 >
