It may be of interest in the future to determine how far DNA methylation continues, if the spreading also occurs in the 5′ direction, and if the spreading is required for paternal silencing of Igf2r and activation of Airn.
We found that for mutations to spread requires (WM - 1)+(WF - 1) > 0. That is, given the sex ratio is constrained to be 1 1, there must be an overall fitness gain summed across the mutant male and female genotypes, as has been pointed out in other contexts [ 28, 30, 46].
For paired serologic estimates, 300 participants were required in order to achieve a 10-percentage-point spread, and 1,150 were required for a 5-percentage-point spread.
The essential viral glycoprotein gB is required for spread of infection via cell-to-cell spread as well as by extracellular particles in vitro and in vivo [16], [48], [49].
These results indicate that simultaneous detection of adenoviruses using dual-fluorescent proteins is suitable for real-time analysis, including identification of infected cells and monitoring of viral spread, which will be required for a complete evaluation of oncolytic adenoviruses.
Viral protein gG is not required for spread in vivo [17], and many of the commonly used PRV viral tracing strains employ insertions at this locus [18].
The presence of a cbhA gene in the xylemic xanthomonads X. fastidiosa and R. solanacearum suggests that this enzyme is absolutely required for spread within xylem vessels.
In contrast, most cells attached to polylysine did not spread within 75 min incubation and LY294002 did not affect spreading ability on polylysine, suggesting that spreading of OCUM-2MD3 cells is dependent on an integrin signalling pathway, and that PI3/Akt activity is required for spreading of gastric carcinoma cells.
Education as spreading of knowledge is required for everyone involved in taking common decisions and hence for the working of democracy (Neurath 1945/1973, 230).
Thus, Crk1/2 and CrkL are physically linked, functionally complement each other during podocyte foot process spreading, and together are required for developing typical foot process architecture.
