BACKGROUND Alterations in DNA methylation in cancer include global hypomethylation and gene-specific hypermethylation. It is not clear whether these two epigenetic errors are mechanistically linked or occur independently. This study was performed to determine the relationship between DNA hypomethylation, hypermethylation and microsatellite instability in(More)
The epigenetic impact of DNA methylation in chronic myelogenous leukemia (CML) is not completely understood. To elucidate its role we analyzed 120 patients with CML for methylation of promoter-associated CpG islands of 10 genes. Five genes were identified by DNA methylation screening in the K562 cell line and 3 genes in patients with myeloproliferative(More)
The DNA hypomethylating drug decitabine (DAC) reactivates silenced gene expression in cancer and is approved for the treatment of the myelodysplastic syndrome. Gene reactivation after DAC is variable and incompletely understood. Here, we established a cell line system (YB5) derived from the SW48 colon cancer cell line to study DAC-induced reactivation. YB5(More)

AIMS To investigate the relationship between vitamin D deficiency and diabetic retinopathy. METHODS In total, 1520 patients with Type 2 diabetes were recruited and divided into three groups according to their fundus oculi results: no diabetic retinopathy (n = 625, 41.12%); non-sight-threatening diabetic retinopathy (n = 562, 36.97%); and sight-threatening(More)
PURPOSE The DNA methylation inhibitor 5-aza-2'-deoxycytidine (DAC) is approved for the treatment of myelodysplastic syndromes (MDS), but resistance to DAC develops during treatment and mechanisms of resistance remain unknown. Therefore, we investigated mechanisms of primary and secondary resistance to DAC in MDS. PATIENTS AND METHODS We performed(More)
Formyl peptides are potent neutrophil chemoattractants. In humans and rabbits, the formyl peptide receptor (FPR) binds N-formyl-Met-Leu-Phe (fMLF) with high affinity (K(d) approximately 1 nM). The mouse FPR (mFPR) is a low-affinity receptor for fMLF (K(d) approximately 100 nM); therefore, other agonists for this receptor may exist. Using mFPR-transfected(More)
Non-enzymatic glycation of proteins by reducing saccharides for instance D-glucose is an important post-translational modification regulating protein function. Already two centuries ago, D-glucose (Glc) was identified in the urine of diabetic patients. Recently, abnormally high level of D-ribose (Rib) in the urine of type 2 diabetics has been discovered,(More)
A fragment of RyR1 (amino acids 4064-4210) is predicted to fold to at least one lobe of calmodulin and to bind Ca(2+). This fragment of RyR1 (R4064-4210) was subcloned, expressed, refolded, and purified. Consistent with the predicted folding pattern, R4064-4210 was found to bind two molecules of Ca(2+) and undergo a structural change upon binding Ca(2+)(More)
Spinal cord injury (SCI) can induce a series of histological, biochemical, and functional changes. Acupuncture is commonly used for SCI patients. Using male rats of spinal cord injury with the New York University (NYU) Impactor, we investigated the response of electroacupuncture (EA), manual acupuncture (MA), and transcutaneous acupoint electrical(More)
