HMGB1 is an abundant protein, 10 6 molecules per cell [ 7 ], which has been postulated as a redox sensor [ 8 ]. (hindawi.com)
Loss of SSH-1L expression decreased the nonphosphorylated, active form of cofilin in SK-BR-3 and MDA-MB-231 cell lines, which was associated with reduced cell motility. (oncotarget.com)
Any obstacles encountered by cells in this process can lead to 'replicative stress' ( Figure 1 ), 1 which may be overcome by replicative stress response proteins, but deficiencies in this response result in accumulated errors in DNA replication and loss of genomic integrity, which lead to cell death.
