The expression of selected metalloproteinases and tissue inhibitors of metalloproteinases (TIMP) was examined in three squamous cell carcinoma (SCC) cell lines (FaDu, SiHa, A431) and a keratinocyte cell line (HaCaT) to determine which metalloproteinases function in SCC invasiveness. A Matrigel invasion assay was used to assess invasiveness of the cell lines. Only the FaDu cell line showed invas...

Pseudomonas aeruginosa is an important opportunistic human pathogen. Certain strains can transmigrate across epithelial cells, and their invasive phenotype is correlated with capacity to cause invasive human disease and fatal septicemia in mice. Four multidrug efflux systems have been described in P. aeruginosa, however, their contribution to virulence is unclear. To clarify the role of efflux ...

Purpose: To investigate the effect of microRNA-16 (miR-16) on glioma cell migration and invasiveness, mechanism involved.Methods: MicroRNA-16 mimic or inhibitor was transfected into human (SHG44) cells. Cell migration, invasiveness morphology were determined using scratch test, Transwell invasion assay, immunohistochemical staining, respectively. Expressions bcl-2, MMP-9 MMP-2, NF-κB1 proteins ...

The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), is native to the Americas. It has rapidly invaded 47 African countries and 18 Asian since first detection of invasion into Nigeria Ghana in 2016. regarded as a super pest based on its host range (at least 353 plants), inherent ability survive wide habitats, strong migration ability, high fecundity, rapid development resistance insect...

The aims of the present paper were to review knowledge about Mediterranean non-indigenous species taxa Cnidaria and Ctenophora (CC NIS), screen risk 98 for their potential invasiveness in Sea approach Italian waters. Of these, 38% are well established basin, 4% known invasiveness, 44% casual, 11% have a taxonomic status unresolved, 3% included category ”cryptogenic”. biodiversity CC NIS has cha...
