Abstract
BACKGROUND Basement membrane (BM) accumulation is a hallmark of micro-vessel disease in diabetes mellitus (DM). We previously reported marked upregulation of BM components in internal thoracic arteries (ITAs) from type 2 DM (T2DM) patients by mass spectrometry. Here, we first sought to determine if BM accumulation is a common feature of different arteries in T2DM, and second, to identify other effects of T2DM on the arterial proteome. METHODS Human arterial samples collected during heart and vascular surgery from well-characterized patients and stored in the Odense Artery Biobank were analysed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). We included ascending thoracic aortas (ATA) (n = 10 (type 2 DM, T2DM) and n = 10 (non-DM)); laser capture micro-dissected plaque- and media compartments from carotid plaques (n = 10 (T2DM) and n = 9 (non-DM)); and media- and adventitia compartments from ITAs (n = 9 (T2DM) and n = 7 (non-DM)). RESULTS We first extended our previous finding of BM accumulation in arteries from T2DM patients, as 7 of 12 pre-defined BM proteins were significantly upregulated in bulk ATAs consisting of > 90% media. Although less pronounced, BM components tended to be upregulated in the media of ITAs from T2DM patients, but not in the neighbouring adventitia. Overall, we did not detect effects on BM proteins in carotid plaques or in the plaque-associated media. Instead, complement factors, an RNA-binding protein and fibrinogens appeared to be regulated in these tissues from T2DM patients. CONCLUSION Our results suggest that accumulation of BM proteins is a general phenomenon in the medial layer of non-atherosclerotic arteries in patients with T2DM. Moreover, we identify additional T2DM-associated effects on the arterial proteome, which requires validation in future studies.

Abstract
The proteins expressed in pancreatic acinar cells during the initiation of acute pancreatitis may determine the severity of the disease. Cerulein pancreatitis is one of the best characterized models for acute pancreatitis. Present study aims to determine the differentially expressed proteins in cerulein-stimulated pancreatic acinar cells as an in vitro model for acute pancreatitis. Rat pancreatic acinar AR42J cells were treated with 10(-8)M cerulein for 12h. The protein patterns separated by two-dimensional electrophoresis using pH gradients of 5-8 were compared between the cells treated without cerulein and those with cerulein. The changed proteins were conclusively identified by matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) analysis of the peptide digests. As a result, 10 proteins (Orp150 protein, protein disulfide isomerase related protein, dnaK-type molecular chaperone hsp72-ps1, mitochondrial glutamate dehydrogenase, similar to chaperonin containing TCP-1 beta subunit, RuvB-like protein 1, heterogeneous nuclear ribonucleoprotein H1, aldehyde reductase 1, triosephosphate isomerase 1, peroxiredoxin 2) were up-regulated while four proteins (vasolin-containing protein, 78 kDa glucose-regulated protein precursor, heat shock protein 8, adenosylhomocysteinase) were down-regulated by cerulein in pancreatic acinar AR42J cells. These proteins are related to chaperone, cell defense mechanism against oxidative stress or DNA damage, anti-apoptosis and energy generation. The differentially expressed proteins by ceruein share their functional roles in pancreatic acinar cells, suggesting the possible involvement of oxidative stress, DNA damage, and anti-apoptosis in pathogenesis of acute pancreatitis. Proteins involved in cellular defense mechanism and energy production may protect pancreatic acinar cells during the development of pancreatitis.

Abstract
Coronary artery blockage, due to cardiovascular disease, is routinely treated by either balloon-angioplasty or bypass surgery. The limited success of these clinical interventions is due at least in part to smooth muscle cell (SMC) proliferation. Here we show that heterogeneous nuclear ribonucleoprotein complex K (hnRNP-K) protein levels increase in SMC with response to serum stimulation in vitro, in the aortas from an animal model of atherosclerosis, and in occluded human vein segments. hnRNP-K is a multi-functional protein that has been studied primarily in cancer cells and has been suggested to play a role in cell cycle progression. We show that in untransformed, cultured SMC, hnRNP-K protein sub-cellular localization modulates through the cell cycle in both the cytoplasm and nucleus. Using cycloheximide, we observed that cytoplasmic accumulation of hnRNP-K protein at later time points in the cell cycle occurred with a concomitant decrease in nuclear hnRNP-K protein, suggesting a translocation of nuclear hnRNP-K protein to the cytoplasm. Also, because we did not observe an increase in hnRNP-K protein at early time points in the cell cycle in the presence of cycloheximide, we propose that the early increase in cytoplasmic hnRNP-K protein following serum stimulation is due to new hnRNP-K protein synthesis. When present in the cytoplasm, hnRNP-K is part of a multi-protein complex that consists of at least two other proteins, calponin and ERK1/2. Our findings from this study are intriguing because they suggest that cytoplasmic hnRNP-K in SMC is part of a signaling complex that may be involved in growth-stimulated post-transcriptional regulation.
