At 6 hours after injection, externalization of PS was observed on the endothelium.
Nevertheless, they represent a surgical condition and resolution of the disease process can only occur after complete externalization or removal of the lesion.
An exemplary efflux study is shown in Fig. 2b and reveals that 28% of the initial cellular [64Cu]NOTA-pentixather activity are retained after 120 min of externalization.
It remains to be determined if the restored pool of functional DOR-eGFP receptors observed at the surface of neurons 24 hours after agonist treatment arises from slow externalization of internal receptor pools or receptor neosynthesis.
There was no significant induction of the AR (P = 0.6) or of PS externalization (P = 0.6) after continuous incubation with any of the compounds compared with vehicle controls (Supplementary data, Fig. S2).
However, after exposure to 2 mM hydrogen peroxide, externalization of phosphatidylserine already became evident at 30 min which was followed later by demonstration of loss of viability and DNA fragmentation at 1h [1h].
Therefore, cytoplasmic tTG binds to and is delivered inside the Rab11-containing PNRC shortly after onset of its biosynthesis but prior to externalization.
Although some apoptotic events such as disruption of mitochondrial membrane and caspase activation are detected after PDT, there is no phosphatidylserine plasma membrane externalization or DNA fragmentation, suggesting that in DU-145 cells the late apoptotic events are missing.
Lee et al. (2010) found that the levels of spermatozoa with apoptotic markers in idiopathic infertility (externalization of phosphatidylserine and DNA fragmentation) decreased after DGC, but the combination DGC + MACS presented even better results.
To test the role of CA-MSC and BM-MSC secretions in the protection of ovarian cancer cells from carboplatin-induced apoptosis, we evaluated the proportion of apoptotic cells in response to carboplatin by analysing phosphatidyl serine externalization and membrane permeability by flow cytometry after Annexin-V-FITC/propidium iodide labelling and PARP cleavage by western blot.
