(Fig.4a). These Piwi-positive cells are usually found symmetrically located on dorsal side in both halves of the middle brain at a distance of ~150 μm from each other and Piwi is exclusively cytoplasmic. As Piwi has been shown to be autonomously required for stem cell maintenance in ...
It is composed in such a way, that coefficients of each row in (4.57) are located in a corresponding column of the set (4.58). In the particular case of mechanism (4.54) we get (4.59)r(1)=1*r(1)'+1*r(2)'r(2)=0*r(1)'+1*r(2)' ...
5b). Either of the point mutation D129A or C151/C154A in ZZ domain abolished the ability of p62 to undergo aggregation in response to the p62 ligands (Fig. 4d). As a control, we confirmed that p62 aggregation is not induced by known autophagic inducers such as rapamycin (Fig. 4b) ...
