Stabilizing of cytokeratin in PLC/PRF/5 cells.
There are two sorted groups of cytokeratin 18 (CK18) in forms of assembly and disassembly in PLC/PRF/5 cells. A subcellular shifting is found in association with conditions of microtubule networks. The finding shows that CK18 mostly in forms of assembly, when microtubule networks are in status. The result also reveals that CK18 is relatively in forms of disassembly, while microtubule networks are disrupted in steps. It indicates that intact microtubule networks are probably a stabilizing factor of assembled CK18. It implies that CK18 is not a stable molecule when the cell is under environmental stress.
