Rapalog-treated (200 nM, ARIAD) and untreated cells were analyzed for subcellular positioning of CK-B or CK-BC283S and cell migration was monitored directly after Rapalog addition.
In mammals, PACSIN 3 associates with the osmotic and mechanosensitive vanilloid-type transient receptor potential channel TRPV4, regulating both subcellular positioning and basal Ca2+ channel activity [69], [70].
Repositioning these elements resulted in rotations of the chromosome that changed the subcellular positions of most genes.
Therefore, the occurrence of ROS-induced oxidative injuries is limited to a small distance (<0.02 μm) from the subcellular position of the sensitizer NPs [54].
The way the cellular uptake of nanoparticles takes place, their subcellular position and the ability to cause toxic effects depend mainly upon the NPs diameter, their surface area, surface chemistry, and charge [124].
It is assumed that TiO2 NPs, if exposed to the UV radiation, induce, depending on their subcellular position, one of the cell death pathways: apoptosis [105, 126], autophagy [127, 128], or necrosis [129, 130], whereas the mechanism of those processes is still insufficiently examined (Fig. 3).
The majority of proteins were located in the following five subcellular positions: cytoplasm (66.7%), cytoskeleton (23.8%), membrane (19%), mitochondrion (19%), and nucleus (19%), while the remaining reside in the vesicle, extracellular region, ribonucleoprotein complex, and endoplasmic reticulum.
It is commonly recognized that the miRNA and its targets must be located in the same subcellular position to make the biological interactions operable, thus the spatial and temporal information of miRNA expression may narrow the search for miRNA target candidates.
The subcellular position of a protein is a key determinant of its function.
To localize protein to the subcellular position, newly identified protein sequences were analyzed by PSORT II Prediction [ 30] (http://psort.hgc.jp/form2.html).hgc.jp/form2.html
The effect of SRPK1 inhibition (using SRPIN340) on SRSF1 subcellular position was examined following induction of SRSF1 translocation to the nucleus using IGF-1 (Nowak et al, 2010).
