OBJECTIVES: Dental tissue-derived mesenchymal stem cells (MSCs)-mediated pulp-dentin regeneration is considered a potential approach for the regeneration of damaged teeth. Enhancing MSC-mediated pulp-dentin regeneration is based on an understanding of the molecular mechanisms underlying directed cell differentiation process. Histone demethylation enzyme, lysine demethylase 1A (KDM1A) can regulate the differentiation of some MSCs, but its role in dental tissue-derived MSCs is unclear. MATERIAL AND METHODS: We obtained SCAPs from immature teeth...

Crosstalk occurs between dyslipidemia and chronic inflammation, which are both precipitants of atherosclerosis. Sterol regulatory element binding proteins cleavage-activating protein (SCAP) plays a key role in regulating cholesterol homeostasis. The present study investigated the effects of SCAP dysfunction on the expression of inflammatory cytokines and lipid metabolism in THP-1 macrophages. Intracellular cholesterol content was assessed by Oil Red O staining and quantitative assays. The expression of SCAP, HMGCR, pro-IL-1β and N-SREBP2, p65(N) in the nucleus were examined by real-time quantitative RT-PCR and Western blotting...

Recently, we have found that human stem cells from apical papilla (SCAP) show a stromal cell-derived inducing activity (SDIA). To examine SDIA competence for retinal cells differentiation, we co-cultured SCAP with human pluripotent stem cells (hPSCs). In comparison with Matrigel-cultured hPSCs, SCAP significantly induces hPSCs to differentiate into rostral neural cells as demonstrated by upregulation of OTX2 and PAX6 and down-regulation of EN1, HOXB4 and HOXC8. Furthermore, the differentiated cells on SCAP significantly expressed eye-field markers, RAX, PAX6, LHX2 and SIX3 and showed five folds pigmented colonies...

Background: Low brain tissue oxygen tension (PbtO2 ), or brain hypoxia, is an independent predictor of poor outcome. Increasing inspirational fraction of oxygen could have a significant influence on treating lower PbtO2 . Combined PbtO2 therapy, compared to the approach that focus only on regulation of cerebral perfusion pressure and intracranial pressure, shows better patient outcomes. Monitoring of PbtO2 could be helpful in individualizing treatment, preventing or limiting secondary brain injury, and maintaining better patient outcome...

The tooth root transmits and balances occlusal forces through the periodontium to the alveolar bone. The periodontium, including the gingiva, the periodontal ligament, the cementum and the partial alveolar bone, derives from the dental follicle (DF), except for the gingiva. In the early developmental stages, the DF surrounds the tooth germ as a sphere and functions to promote tooth eruption. However, the morphological dynamics and factors regulating the differentiation of the DF during root elongation remain largely unknown...

AIM: Although statins are considered a cornerstone for the treatment of high cholesterol levels due to their powerful cholesterol-lowering effects, response to drug administration is still one of the main pitfalls of statin treatment. So far, the reasons underlying this undesired outcome are still poorly understood, but recently, various studies have suggested that miRNAs may be involved. Therefore, we aimed at evaluating the effect of short-term low-dose treatment with 2 statins on miRNAs expression in patients with hypercholesterolemia...

Secondary damage following spinal cord injury leads to non-reversible lesions and hampering of the reparative process. The local production of pro-inflammatory cytokines such as TNF-α can exacerbate these events. Oligodendrocyte death also occurs, followed by progressive demyelination leading to significant tissue degeneration. Dental stem cells from human apical papilla (SCAP) can be easily obtained at the removal of an adult immature tooth. This offers a minimally invasive approach to re-use this tissue as a source of stem cells, as compared to biopsying neural tissue from a patient with a spinal cord injury...
