当将人皮肤鳞状细胞癌细胞系的培养细胞从低钙(0.07 mM)转移到高钙(1.87 mM)培养基时,观察到与角蛋白中间丝(KIF)重组相关的桥粒细胞-细胞接触的形成。在低钙时,细胞分散,没有桥粒细胞-细胞接触,KIF主要集中在细胞核周围。转移15分钟后,细胞彼此接触并形成小集落,KIF开始显示放射状排列。除了细胞-细胞接触形成和KIFs重排外,转移诱导颗粒相关蛋白激酶C(C-激酶)活性增加四倍。当12-O-十四酰基佛波醇-13-乙酸酯(PMA),它特异性激活C-激酶,加入到低钙培养基中生长的细胞,细胞-细胞接触的形成和KIF束的径向排列几乎相同的转移到高钙培养基中所诱导的观察。这些数据表明C激酶活性的增加与KIF重排相关的细胞-细胞接触的形成之间存在相关性。
Formation of desmosomal cell-cell contact associated with reorganization of keratin intermediate filaments (KIFs) was observed when cultured cells of a cell line of human skin squamous cell carcinoma were transferred from low (0.07 mM) calcium to high (1.87 mM) calcium medium. At low calcium, cells were dispersed without desmosomal cell-cell contact and the KIFs were mostly concentrated around the nucleus. After 15 min of the transfer, cells contacted each other and formed small colonies and the KIFs initiated to show a radial arrangement. In addition to the cell-cell contact formation and rearrangement of KIFs, the transfer induced fourfold increase of particulate-associated protein kinase C (C-kinase) activity. When 12-O-tetradecanoyl phorbol-13-acetate (PMA), which specifically activates C-kinase, was added to the cells grown at low calcium medium, cell-cell contact formation and radial arrangement of KIF bundles almost identical to those induced by the transfer to high calcium medium were observed. These data suggest a correlation between an increase in C-kinase activity and formation of cell-cell contacts associated with rearrangements of KIFs.
