“…The purpose of using WGA as a probe is that it is a member of the lectin family that binds to N-acetyl-D-glucosamine and sialic acid residues found on the surface of cell membranes. It has been used extensively to stain surface of membranes [26] better than the usage of phalloindin toxins, for example, which in turn label the actin cytoskeleton, providing an indirect labeling of the membrane and not this component itself. A WGA staining of unstimulated cells is shown in order to exclude any possible membrane reorganization due to Ang-II ( Fig 1D).…”

“…Since our previous demonstrated that nucleoplasmic Ca 2+ regulates cell proliferation [12, 29, 30] and the activation of ACE by Ang-II caused preferential nuclear Ca 2+ increase, we investigated the role of ACE in cell growth. Ang-II stimulated CHO-ACE cells to proliferate faster compared to control non-stimulated group (CHO-ACE cells reached 1.1 ± 0.28 x 10 4 cells vs 1.5 x 10 3 ± 0.25 cells from the control group, after 15 hours of incubation in the presence of Ang-II, n = 4, p<0.05), ( Fig 4A) .…”

“…The increase of expression, or activity, of Ca 2+ channels in the plasma membrane leads to increase of Ca 2+ influx, promoting Ca 2+ -dependent cell proliferation, and differentiation [4]. In contrast, the nucleoplasmic reticulum can release Ca 2+ independently of signals generated by cytosolic Ca 2+ [5], microdomain where Ca 2+ is able to bind to specific DNA promoter regions, modulating the activity of transcription factors, gene expression and cellular activity [6].…”

“…Em decorrência disso, a proliferação celular é estimulada. Porém, o tamponamento do Ca 2+ nuclear reduz a superexpressão tanto da ADAM-17 quanto do EGFR, induzidos pela radiação X, indicando que a possibilidade de associar o tamponamento do Ca 2+ nuclear com a radiação ionizante uma estratégia terapêutica (52).…”
