Regulation of motility in nonmuscle cells
In the past several years actomyosin contractile systems have been related to many types of cell movement and other functions such as cytoplasmic streaming, cytokinesis, blood clot retraction, and phagocytosis. The evidence for the presence of actin and myosin in nonmuscle cells is now widespread and has been the subject of a recent review (85) and two recent published symposia (31, 43). Regula...
متن کاملMechanisms of motility in metastasizing cells.
Cell migration and invasion are critical parameters in the metastatic dissemination of cancer cells and the formation of metastasis, the major cause of death in cancer patients. Migratory cancer cells undergo dramatic molecular and cellular changes by remodeling their cell-cell and cell-matrix adhesion and their actin cytoskeleton, molecular processes that involve the activity of various signal...
متن کاملRadiation-induced motility alterations in medulloblastoma cells
Photon irradiation has been repeatedly suspected of increasing tumor cell motility and promoting locoregional recurrence of disease. This study was set up to analyse possible mechanisms underlying the potentially radiation-altered motility in medulloblastoma cells. Medulloblastoma cell lines D425 and Med8A were analyzed in migration and adhesion experiments with and without photon and carbon io...
متن کاملIn vitro effects of kraft liquor on testicular cells and sperm motility of Caspian kutum (Rutilus frisii kutum)
To identify Kraft liquor effects on spermatogenesis and sperm motility of Caspian kutums by using in vitro culture, the fish testis was incubated with 5, 10 and 15 % (V/V) of liquor for 3 and 6 days. The percentage of motile spermatozoa and its total duration were also measured. Adverse effects on testicular cells were more apparent with the increase of liquor concentrations. The mean size of s...
