The relationship between structure and function of the nucleosome is an area of exciting and intense research, exemplified by the recent report of the first high-resolution crystallography data (5). The nucleosome, the basic unit of chromatin, consists of DNA wrapped around the core histones H3, H4, H2A and H2B. This structure serves not only to package and organize the two meters of DNA found ...

Compared with chemical synthesis, fermentation has the advantage of mass production at low cost, and has been used in the production of various industrial chemicals. As a valuable organic compound, 1,3-propanediol (1,3-PDO) has numerous applications in the production of polymers, lubricants, cosmetics and medicines. Here, conversion of glycerol (a renewable substrate and waste from biodiesel pr...

increment. it is categorized based on genetic aberrations. some of these genetic disorders can determine minimal residual diseases (mrd) and prognosis of aml patients. wilms tumor (wt1) over expression is found in aml patients. the aim of this study was to determine the frequency of wt1 over expression in aml pediatric cases in north -east of iran. materials and methods: this retrospective stud...

  Background and Objectives: Adenoid cystic carcinoma (ACC), the most common malignant tumor of submandibular and minor salivary glands, is characterized by a high rate of local recurrence and distant hematogenous metastasis and tendency to invade peripheral nerves. In spite of radiotherapy and surgical treatment, the long-term prognosis is dismal. Today, many studies are being conducted using...

programmed cell death-1 (pd-1) and its ligands, pd-l1 and pd-l2, have been regarded as important immune system regulatory molecules. the aberrant expression of the molecules has been related to several autoimmune disorders. this study is aimed to assess the mrna expression level of pd-1, pd-l1, and pd-l2 molecules in the peripheral blood mononuclear mells (pbmcs) from multiple sclerosis (ms) pa...

conclusions dlec1 suppresses tumor cell growth the presence of ap-2α2 and stimulates cell proliferation in the down-regulation of ap-2α2 in dlec1 over-expression stable clones of htc116. results the dlec1 over-expression was found to reduce the number of colonies in colony formation and to induce g1 arrest in seven clones, and apoptosis in one clone in the cell cycle analysis. furthermore, rega...

Background: Acute myeloid leukemia (AML) is one of myeloid malignancies which the risk increases with age increment. It is categorized based on genetic aberrations. Some of these genetic disorders can determine minimal residual diseases (MRD) and prognosis of AML patients. Wilms tumor (WT1) over expression is found in AML patients. The aim of this study was to determine the frequency of WT1 ove...
