AB  - OBJECTIVE The study aimed to investigate acetylsalicylic acid (ASA) effects on osteo/odontogenic differentiation and proliferation of dental pulp stem cells (DPSCs) in vitro and the potential involvement of adenosine monophosphate-activated protein kinase (AMPK) pathway in these processes. DESIGN DPSCs were isolated from third molars pulp tissues of five patients and grown in osteogenic medium alone or supplemented with ASA. Expression of DPSCs markers was tested by flow-cytometry. Cytotoxicity of ASA at concentrations of 10, 50 and 100 µg/ml was tested by MTT and NR assays. Osteo/odontogenic differentiation was analyzed via alizarin red staining and ALP activity. Quantitative PCR (qPCR) was used for osteo/odontogenic markers' (DSPP, BMP2, BMP4, BSP, OCN and RUNX2) and c-Myc expression analysis. AMPK inhibition of ASA-induced osteo/odontogenesis was tested by qPCR of selected markers (DSPP, OCN and RUNX2). RESULTS Cytotoxicity assays showed that only the highest ASA dose decreased cell viability (89.1 %). The smallest concentration of ASA applied on DPSCs resulted in a remarkable enhancement of osteo/odontogenic differentiation, as judged by increased mineralized nodules' formation, ALP activity and gene expression of analyzed markers (increase between 2 and 30 folds), compared to untreated cells. ASA also increased DPSCs proliferation. Interestingly, AMPK inhibition per se upregulated DSPP, OCN and RUNX2; the gene upregulation was higher when ASA treatment was also included. c-Myc expression level decreased in cultures treated with ASA, indicating undergoing differentiation processes. CONCLUSIONS Low concentrations of ASA (corresponding to the standard use in cardiovascular patients), were shown to stimulate osteo/odontogenic differentiation of dental pulp stem cells.

AB  - The aim of this study was to assess the effect of type 1 diabetes mellitus (induced by a single intravenous injection of 100 mg kg(-1) of alloxan) on acetylcholine (ACh)-induced relaxation in isolated rabbit parotid gland feeding artery. Isometric force measurements and quantification of inducible nitric oxide synthase (iNOS) mRNA by real-time RT-PCR were made in parotid artery rings from diabetic and control rabbits. Acetylcholine induced concentration- and endothelium-dependent vasorelaxation that was significantly decreased in parotid artery rings from diabetic rabbits. Schild analysis of the ACh vasorelaxant effect, in the presence of selective muscarinic receptor antagonists, revealed involvement of the M(3) receptor subtype in parotid artery rings from both control and diabetic rabbits, with no change in antagonist affinity constants. The inhibitory effects of indomethacin, a non-selective inhibitor of cyclooxygenase, and of high potassium, an inhibitor of hyperpolarization, on ACh vasorelaxation were increased. The effect of N(G)-nitro-L-arginine, a non-selective inhibitor of NOS, was decreased in diabetes. S-methylisothiourea, a selective inhibitor of iNOS, significantly reduced ACh vasorelaxation only in parotid artery rings from diabetic rabbits. Also, up-regulation of iNOS mRNA expression was detected in parotid artery rings from diabetic rabbits. These results suggest that in parotid artery rings from diabetic rabbits, impaired endothelium-dependent vasorelaxation to ACh appears to be caused by the loss of a nitric oxide-mediated component and increased iNOS expression, and is unlikely to be caused by a change at the M(3) receptor level.
