Our hypothesis that Ndk acts as a potential inhibitor of phagosome maturation was supported by i) our recent findings that live mycobacteria express a GAP-like activity on Rab7 that has been recruited to the phagosome [17] and ii) by concomitant demonstration that mycobacterial Ndk acts as a GAP for Rho-GTPases [26].
Consistent with previous findings, GPs in our study expressed a gap of uncertainty between recognition and management and had to use available – although inadequate strategies - for bridging this gap, e.g. avoiding the subject of MUS, addressing only single 'valid' symptoms in the consultation or offering less reasonable tests and referrals [ 30].
In contrast, in cells co-expressing Arf6Q67L a gap junction-like cell cell interface typically remained only in small regions (indicated by arrows in Fig. 5d).
We conclude that confluent monolayers of DPSCs express the gap junction-forming protein Connexin-43 and upon IIF retain membrane integrity, however lose the ability to proliferate.
This is not due to lack of connectivity through gap junctions, since embryonic stem cells have been shown to express functional gap junctions, but is rather explained by the absence of functional voltage-dependent Ca2+ channels.
But my concern is always, did the film say what I wanted to express or advocate?" After a gap of 13 years, he returned to the screen as an actor in Steven Spielberg's Jurassic Park (1993), as the mad genius who runs the theme park featuring genetically recreated dinosaurs, a role which he was to repeat in the sequel The Lost World (1997).
This suggests that engineering skeletal muscle to express gap junction proteins in vivo may induce similar coupling with host myocardium.
Although contractile under field stimulation, skeletal muscle grafts do not express gap junction proteins and remain electrically insulated, suggesting they may not beat with host myocardium.
Based upon a previously published work showing that secreted Mtb Ndk manipulates the Rho GTPase regulatory cycle [26] and our recent observation that pathogenic mycobacteria express GAP activity towards Rab7 GTPase [17], we over-expressed and purified recombinant Mtb Ndk to homogeneity and examined its interaction with both Rab7, and the closely-related molecule, Rab5.
Immature neurons arising from cell division express GAP 43 and doublecortin; they differentiate to fully mature neurons expressing OMP (Olfactory Marker Protein) [24] and olfactory receptors at the tip of their dendrite, when establishing synapses with the apical dendrite of mitral/tufted cells in the OB.
BECs also express gap junctions but their functional significance is not clear.
