The reduced replication of the ΔA51R strain at later time points of infection during in vitro and in vivo infections was not caused by a reduction in the extracellular enveloped (EEV) form of VACV, which primarily mediates spread of the virus (Smith et al., 2002).
Indeed, active Rac1, e.g., by triggering integrin activation and actin polymerization, can mediate the R-Ras-elicited and integrin-mediated spreading of ECs on matrix proteins.
To further confirm the ability of CS1 peptides to mediate spreading, OSCC cells were plated onto surfaces coated with immobilized peptides coupled with BSA.
Similarly, K+ channels responsible for potassium buffering when under pathological stress can add to accumulation of extracellular K+ and mediate spreading depression (Nedergaard and Dirnagl, 2005).
Anchored PrP expressed on neurons mediates spread of prions along axons in the peripheral and central nervous systems.
In dSETDB1 R436C) cells, SETDB1, (me3)H3-K9, 5mC, and Dnmt2 occupied the PDE but not the PPE or Exon-I, which indicates that MBDL mediates the spreading of (me3)H3-K9 and mDNA from the PDE to the coding region (Figure 5A; Fig. S18).
Similar to the SIR complex, sequential cycles of Swi6 binding and Clr4 recruitment have been proposed to mediate the spreading of H3K9 methylation along the chromatin fibre (Nakayama et al, 2001; Grewal and Moazed, 2003).
The compounds RBC6, RBC8 and RBC10 inhibited the binding of Ral to its effector RALBP1, as well as inhibiting Ral-mediated cell spreading of murine embryonic fibroblasts and anchorage-independent growth of human cancer cell lines.
These results confirm further that the bioactive RGDS peptide displayed on the surface is mediating the adhesion and spreading of the cells.
Laminin mediates tethering and spreading of colon cancer cells in physiological shear flow.
