Observe actin filament remodeling using the Lenti-X Actin Dynamics Monitoring Kit. Actin filaments are completely remodeled in HeLa cells in less than 1 hr. Panel A. Self-assembly of actin filaments occurs at the plus end of an existing actin filament as monomeric actin is incorporated. Conversely, disassembly occurs at the minus end where actin monomers depolymerize from the filament, causing a continuous rearrangement of the actin filament network. HeLa cells were infected with constructs encoding mCherry human alpha-Actin and DD-AcGPF1 human alpha-Actin. Cells were fixed using 4% paraformaldehyde and imaged with a 40X objective. Fluorescence micrographs were taken 1 hr after addition of Shield1 (Panels E-G) or without Shield1 (Panels B-D). In the absence of Shield1, DD-AcGFP1-Actin was degraded quickly (Panels C & D) despite a normal, mCherry-labeled actin filament network (Panels B & D). In the presence of Shield1, DD-AcGFP1-Actin was stabilized and present in the actin filament network along with mCherry-labeled Actin (Panels E-G). Our results are in agreement with a previous report that the actin filament network rearranges completely in 1 hr in PtK2 epithelial cells, but we used the extremely simple ProteoTuner-based method, rather than the extremely laborious microinjection method.
