Although hypoxic environments have been known to regulate the migratory ability of bone marrow-derived mesenchymal stem cells (BM-MSCs), which is a critical factor for maximizing the therapeutic effect, the underlying mechanisms remain unclear. Therefore, we aimed to confirm the effect of hypoxia-inducible factor-1α (HIF-1α) on the migration of BM-MSCs and to analyze the interaction between HIF...
The aim was to determine whether gum Arabic (GA) supplementation prevents cognitive decline in type 2 diabetes, through stimulation of mitochondrial function the hippocampus. Type diabetic rats and controls were assigned following groups for 16 weeks: Control + Water; GA 10% w/v; Diabetes w/v. Latency water maze shorter compared Water (P < 0.05). group had a higher expression density per cell p...
We previously found that clioquinol (CQ) increases functional hypoxia-inducible factor-1α (HIF-1α) with enhanced transcription of its target genes. Here we report that compounds derived from 8-hydroxyquinoline including CQ, broxyquinoline (BQ), iodoquinol (IQ) and chloroacetoxyquinoline (CAQ) promote neovascularization effectively based on chick chorioallantoic membrane assays. The CQ analogues...
BACKGROUND Hypoxia-inducible factor 1 (HIF-1), a master regulator of oxygen homeostasis, is a heterodimer consisting of HIF-1α and HIF-1β subunits, and is implicated in calcification of cartilage and vasculature. The goal of this study was to determine the relationship between serum HIF-1α with coronary artery calcification (CAC) in patients with type 2 diabetes. METHODS The subjects were 405...
Endogenous retroviral sequences are present in high copy numbers in the genomes of all species and may be expressed as RNAs; however, the majority are defective for virus production. Although virus has been isolated from various Old World monkey and New World monkey species, there has been no report of endogenous retroviruses produced from African green monkey (AGM) tissues or cell lines. We ha...
چکیده سابقه و هدف: تغییر در فعالیت و محتوای pgc-1α احتمالاً به دلیل پلی مورفیسم های آن اثرات گسترده ای برروی فرایندهای متابولیک در افراد مبتلا به دیابت نوع 2 (t2d) دارد. نتایج متفاوت و متناقضی در مورد ارتباط پلی مورفیسم rs2970847 ژن pgc-1α و t2d گزارش شده است. این مطالعه با هدف تعیین ارتباط پلی مورفیسم thr394thr ژنpgc-1α و t2d به روش مروری و متاآنالیز انجام گرفت. روش بررسی: این مرور سیستماتیک به...
pound (1 7) with useful clinical activity ( 16), a wide variety of pyrimidines and nucleoside analogs of various types have been synthesized and their biologic and biochemical activities de scribed. This laboratory has been engaged in the synthesis and study of a number of other fluorinated pyrimidines (cf 14), among which the most interesting are FUR, FUDR (14), and F3TDR (18). Recently we hav...
سابقه و هدف: یکی از شیوههای رایج مصرف اتانول، مصرف افراطی آن میباشد که با وجود پرهیز، مصرف آن با اختلالات رفتاری طولانی مدتی همراه است. بنابراین، یافتن روشهایی که بتواند در زمانی کوتاه این اختلالات را بهبود بخشد، از اهمیت زیادی برخوردار است. این مطالعه با هدف بررسی اثر کورکومین و تمرین شنا پس از مصرف افراطی اتانول بر بیوژنز میتوکندریایی بافت هیپوکامپ رتهای نر انجام شد. مواد و روشها: در یک ...
Although cells derived from periodontal ligament (PDL) tissue are reported to have stem cell-like activity and are speculated to play a crucial role for tissue healing and regeneration after injury or orthodontic treatment, mechanisms regulating their recruitment and activation remain unknown. Recently, stromal cell-derived factor 1α (SDF-1α) has been reported to be important for stem cell homi...
BACKGROUND/AIMS There have been many studies on the etiology of osteoarthritis (OA) with regard to the function of inflammatory cytokines, the process of cartilage degradation, the function of miR-146a, hypoxia stimulation and autophagy in OA chondrocytes, but there have been no reports on the relationship between miR-146a and autophagy in cartilage, especially under hypoxia. This study aimed t...
