  • Costameres are subsarcolemmal protein assemblies in striated muscle cells that circumferentially align in register with the Z disk of peripheral myofibrils and physically couple force-generating sarcomeres with the sarcolemma. (grantome.com)
  • HEp-2 cells preincubated within the absence or presence of NH4Cl for 30 min had been subsequently treated with Pet for 3 h within the absence or presence of NH4Cl. (orthodontistlamesa.com)
  • Our results revealed that the expression of HSP70 and HSP20 was initially triggered after 2 h of heat shock, and one of the HSP70 genes was potentially regulated by HSF1 . (biomedcentral.com)
  • Furthermore, semaphorin 3A promotes the formation of intra-axonal F-actin bundles in concert with the loss of F-actin in growth cone lamellipodia and filopodia. (biologists.com)
