Atherosclerosis is an important underlying pathology of cardiovascular diseases, the leading cause of death in developed countries with increasing incidence trends in developing countries. Recently, the pathogenesis of atherosclerosis is widely attributed to vascular inflammation. An increasing number of studies have demonstrated the crucial role of inflammation in each stage of atherosclerosis ranging from initiation through progression to the formation of thrombotic complications. Moreover, vascular endothelial dysfunction induced by hyperlipidemia, hypertension, free radicals, WY 14643 PPAR inhibitor diabetes, infection, shear stress and other factors is regarded as one of the first steps toward plaque formation. Salusins is a new class of vasoactive peptides originally identified by Shichiri et al. in 2003, which includes salusin-a and salusin-b consisting of 28 and 20 amino acids respectively. Our results suggest that the trapping of sumo1 in the lamin A/C aggregates may conceal sumoylated proteins from normal deconjugation and/or sumo1 degradation. Furthermore, although not sequestered within the aggregates, we found ubc9 to colocalize with both wild-type and mutant lamin A/C regardless of aggregation phenotype. This co-localization of ubc9 at lamin aggregates may be maintaining or promoting the higher levels of sumoylation as observed. Indeed, global levels of sumo modification can be altered by affecting ubc9 activity. As there are hundreds of proteins known to undergo sumoylation, the consequences of sumo1 mislocalization could have disastrous consequences on the regulation of many cellular processes. Previous research in cardiac and skeletal muscles of the LmnaH222P/H222P mouse demonstrated an increase in the nuclear accumulation of Smad proteins, in the mice. Both the TGFb receptor type I,NVP-BEZ235 915019-65-7 which activates the Smad proteins, as well as Smad4 are sumoylated. TbRI is sumoylated in response to TGFb and amplifies the signal by modulating gene expression. However, there are conflicting reports as to whether sumoylation stimulates or represses Smad4. The nuclear accumulation of Smad proteins may be the result of altered Smad4 and/or TbRI sumoylation in the presence of lamin A/C mutants. The cellular dynamics behind the development of striatedmuscle specific laminopathies is not well understood. Our results provide further insight into the tissue-specific cellular regulation that is altered as a result of the LMNA mutations, suggesting that disease-associated mutations in the LMNA gene mediate a mislocalization of sumo1, ubc9, and likely sumoylated proteins in a mutation-dependent manner. Consequently, deficient deconjugation and/or degradation of sumo1 occurs, indicating a misregulation of the sumoylation process. According to the connections between the cortex and the striatum and the reduced capacity of BDNF synthesis by striatal neurons, BDNF loss in the striatum after stroke may be linked to the stimulation or the inhibition by the DAPT molecular weight lesion of BDNF axonal transport from the striatum towards the cortex or from the cortex to the striatum, respectively as BDNF can be transported in the axon in both anterograde and retrograde directions.
