Figure 11.1 The intracellular trafficking pathway of plasmid DNA complexed by poly cationic lipid (lipoplex). Critical steps are indicated by numbers (1) endocytosis, sorting and recycling via vesicular compartments comprising the early (EE) and sorting endosomes (2) entrapment and degradation in the late-endosomes (LE) and lysosomes (3) destabilization of the endo-lysosomal membrane and release into the cytosol, (the precise location of this step is not known) (4) diffusion toward the nuclear pore complex (NPC) and degradation in the cytoplasm, and (5) nuclear translocation across the NPC.

Figure 3 Quantifying nuclear trafficking - Experimental ratios of the amount of NF-kB antibody staining in the nucleus as compared to the cytoplasm, for unstimulated and stimulated (10 ng/ml TNF-a) HeLa cells. The Z-factor for the assay was 0.73. The CV was 6.3%...

The function of SIOOP has never been determined with precision however, it is thought to function in intracellular calcium trafficking, or microtubular assembly, or both. It has a loose physiologic relationship to calmodulin, another calcium flux protein.There are two subunits to SIOOP—alpha and beta—yielding three possible dimeric forms alpha-alpha alpha-beta and beta-beta. Melanocytes synthesize only the hrst of those combinations. Immunoreactivity for SIOOP should be both nuclear and cytoplasmic in order to be regarded as valid. Immunoelectron microscopic studies... [Pg.192]
