Monomeric (G), total (T) and filamentous (F) actin and the state of actin polymerisa­tion (F:G) were determined and actin filaments were visualized in hepatoma Morris 5123 cells cultured in the presence of methotrexate (MTX) at various concentration. The exposure of the cells to this drug resulted in a decrease of total and polymerised actin in cytoplasm and in some changes in actin filament organization. This coincided with a decrease of the cells' ability to migrate through Matrigel coated filters and with inhibition of tumour formation after reimplantation of the methotrexate treated cells to experimental rats.

In order to compare the ability of different isoforms of myosin essential light chain to interact with actin, the effect of the latter protein on the proteolytic susceptibility of myosin light chains (MLC-1S and MLC-1V — slow specific and same as ventricular isoform) from slow skeletal muscle was examined. Actin protects both slow muscle es­sential light chain isoforms from papain digestion, similarly as observed for fast skel­etal muscle myosin (Nieznańska et al., 1998, Biochim. Biophys. Acta 1383: 71). The ef­fect of actin decreases as ionic strength rises above physiological values for both fast and slow skeletal myosin, confirming the ionic character of the actin-essential light chain interaction. To better understand the role of this interaction, we examined the effect of synthetic peptides spanning the 10-amino-acid N-terminal sequences of myo­sin light chain 1 from fast skeletal muscle (MLC-1F) (MLCFpep: KKDVKKPAAA), MLC-1S (MLCSpep: KKDVPVKKPA) and MLC-1V (MLCVpep: KPEPKKDDAK) on the myofibrillar ATPase of fast and slow skeletal muscle. In the presence of MLCFpep, we observed an about 19% increase, and in the presence of MLCSpep about 36% increase, in the myofibrillar ATPase activity of fast muscle. On the other hand, in myofibrillar preparations from slow skeletal muscle, MLCSpep as well as MLCVpep caused a lowering of the ATPase activity by about 36%. The above results suggest that MLCSpep induces opposite effects on ATPase activity, depending on the type of myofibrils, but not through its specific N-terminal sequence — which differs from other MLC N-terminal peptides. Our observations lead to the conclusion that the action of different isoforms of long essential light chain is similar in slow and fast skeletal muscle. However the interaction of essential light chains with actin leads to different physiological effects probably depending on the isoforms of other myofibrillar proteins.

Gelsolin, one of a major actin-binding proteins, is involved in the regulation of actin cytoskeleton organization by its severing and capping activity towards actin filaments. Human colon adenocarcinoma cell line LS180 and its selected variants of different metastatic potential were used to check for a correlation between gelsolin level, its subcellular localization and the invasive capacity of cells. Based on immunoblotting experiments, a decreased level of gelsolin was detected in the most invasive 5W subline when compared to the parental cell line LS180. The intracellular distribution of actin filaments and gelsolin in colon adenocarcinoma cells was examined by confocal microscopy. In the 5W subline, unlike in the other examined cells, gelsolin was colocalized with filamentous actin at the cell periphery. In summary, in human colon adenocarcinoma cells, gelsolin level and its subcellular distribution seem to correlate with their metastatic potential.

Actin is a globular multi-functional protein that forms microfilaments, and participates in many important cellular processes. Previous study found that Haemonchus contortus actin could be recognized by the serum of goats infected with the homology parasite. This indicated that H. contortus actin could be a potential candidate for vaccine. In this study, DNA vaccine encoding H. contortus actin was tested for protection against experimental H. contortus infections in goats. Fifteen goats were allocated into three trial groups. The animals of Actin group were vaccinated with the DNA vaccine on day 0 and 14, and challenged with 5000 infective H. contortus third stage larval (L3) on day 28. An unvaccinated positive control group was challenged with L3 at the same time. An unvaccinated negative control group was not challenged with L3. The results showed that DNA vaccine were transcribed at local injection sites and expressed in vivo post immunizations respectively. For goats in Actin vaccinated group, higher levels of serum IgG, serum IgA and mucosal IgA were produced, the percentages of CD4+ T lymphocytes, CD8+ T lymphocytes and B lymphocytes and the concentrations of TGF-β were increased significantly (P<0.05). Following L3 challenge, the mean eggs per gram feces (EPG) and worm burdens of Actin group were reduced by 34.4% and 33.1%, respectively. This study suggest that recombinant H. contortus Actin DNA vaccine induced partial immune response and has protective potential against goat haemonchosis.

Functions of nuclear polymeric proteins such as lamin A/C and actin in transport of plasmid DNA were studied. The results show that the lamina plays an important role in plasmid DNA’s entry into the cell nucleus from the cytoplasm. Selective disruption of lamin A/C led to a halt in plasmid DNA transport through the nuclear envelope. Inside the nucleus, plasmid DNA was frequently localized at sites with impaired genome integrity, such as DNA double-strand breaks (DSBs), occurring spontaneously or induced by ionizing radiation. Polymeric actin obviously participates in nuclear transport of plasmid DNA, since inhibition of actin polymerization by latrunculin B disturbed plasmid transport inside the cell nucleus. In addition, precluding of actin polymerization inhibited plasmid co-localization with newly induced DSBs. These findings indicate the crucial role of polymeric actin in intranuclear plasmid transport

Inhibition of Rho-associated protein kinase (ROCK) activity in glioma C6 cells induces changes in actin cytoskeleton organization and cell morphology similar to those observed in other types of cells with inhibited RhoA/ROCK signaling pathway. We show that phosphorylation of myosin light chains (MLC) induced by P2Y2 receptor stimulation in cells with blocked ROCK correlates in time with actin cytoskeleton reorganization, F-actin redistribution and stress fibers assembly followed by recovery of normal cell morphology. Presented results indicate that myosin light-chain kinase (MLCK) is responsible for the observed phosphorylation of MLC. We also found that the changes induced by P2Y2 stimulation in actin cytoskeleton dynamics and morphology of cells with inhibited ROCK, but not in the level of phosphorylated MLC, depend on the presence of calcium in the cell environment.

Platelets respond to stimuli by rapidly changing from discs into active forms having lamellipodia and filopodia. Actin filament fragmentation and assembly are essential for platelet shape change. Actin assembly is regulated by an intracellular signaling pathway that involves calcium and the activation of small GTPases and phosphatidylinositol kinases (PI-kinases). Polyphosphoinositides (ppIs), the final products of the PI-kinases, directly interact with a special class of actin associated proteins, the barbed end capping proteins, to initiate actin filament assembly in activated cells.
