How can you use “anchorage-dependent” in a sentence? Here are some example sentences to help you improve your vocabulary:
The murine cell line 10T1/2 and the human cell line MDAH, both of which are anchorage-dependent fibroblasts, were detached from their tissue culture dishes and cultured further on HEMA-coated plates.
This protein acts as inhibitor of cyclin-dependent kinases (the "cell cycle engine" [ 50 ] ), and its elevated expression has been consistently demonstrated in different cell types after the disruption of cell-matrix interactions (compare Figure 1and [ 31 32 51 52 ] ). Furthermore, p27 Kip1is an established target of PTEN signaling, i.e., its activity has been found increased after the forced expression of exogenous PTEN [ 53 54 55 56 ] . In combination with the data presented in this manuscript, it therefore appears that PTEN contributes to anchorage-dependent growth control by a two-fold approach: the dephosphorylation of the signaling molecule FAK in combination with the stimulation of the cell cycle inhibitor p27 Kip1.
Collectively, they have established that the expression of cyclin A and cyclin D, in combination with the activity of the cyclin-dependent kinase inhibitors p21 Cip1and p27 Kip1, is a crucial determinant of anchorage-dependent cell growth culture [ 27 28 29 30 31 32 ] . However, while the above elements clearly are essential executioners of cell cycle progression, it is conceivable that other elements, directly or indirectly, might be involved in anchorage-dependent growth control as well.
In view of PTEN's potent growth-inhibitory capacity, we conclude that its induction after cell-matrix disruptions contributes to the maintenance of the anchorage-dependent phenotype of normal cells.
As an alternative to the forced expression of ectopic PTEN in anchorage-independent, PTEN-negative tumor cells, our study has focused on the regulation of endogenous PTEN in anchorage-dependent mouse and human fibroblasts.
