(17) We also show that proliferation of primary amnion cells is not dependent on a high c-fos expression, suggesting that the function of c-fos is more likely to be associated with other cellular functions in the differentiated amnion cell.
(18) The high amino acid levels in the cells suggest that these cells act as inter-organ transporters and reservoirs of amino acids, they have a different role in their handling and metabolism from those of mammals.
(19) We have investigated the effect of methimazole (MMI) on cell-mediated immunity and ascertained the mechanisms of immunosuppression produced by the drug.
(20) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.
Senescence
Definition:
(n.) The state of growing old; decay by time.
Example Sentences:
(1) The proliferation of this cell type may represent an escape from the senescence pathway and progression to immortal tumor cells.
(2) In senescent rats, however, the proportions of salt-soluble and detergent-soluble AChE may differ from those in young rats.
(3) In addition, we have shown that long-lived, presumably non-senescent, strains do not arise by suppressor mutation, but lose senescence plasmid DNA by another mechanism.
(4) Senescent (26-28 months) Fischer 344 rats were shown to have a lower density of D2 sites (-36%) without any change in affinity in membranes prepared from homogenized caudate-putamen (CPU), as compared to young adult (5-6 months) rats.
(5) The cell cycle-dependent changes in the transglutaminase mRNA levels strongly support the implicated involvement of the enzyme in cell growth, differentiation, and senescence.
(6) The increased levels of HK1 could affect other erythrocyte metabolic pathways slowing down the physiological rate of cellular senescence and result in increased activity levels of other cell-age-dependent enzymes.
(7) Advancing age was associated with a reduction in cell proliferative responses to PHA in both substrains, although the rate of decline was significantly more rapid in the senescence-prone animals.
(8) Instead of degenerative changes, these results show an activation of the vasopressinergic system in senescence and in SDAT patients, similar to earlier observations in the aged rat and in accordance with a rise in human neurophysin and VP levels reported recently.
(9) Thus, constitutive expression of specific cytochrome P450 genes is repressed or activated in senescent rats.
