Background & Objectives: Anaplastic lymphoma Kinase (ALK) is a receptor tyrosine kinase involved in the genesis of several human cancers. ALK was initially identified because of its involvement in anaplastic large cell lymphoma (ALCL). ALK is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. Studies reveal that the presence of anti-ALK antibodies ...

background treatment with peginterferon alpha-2b plus ribavirin is the current standard therapy for chronic hepatitis c (chc). however, many host related and viral parameters are associated with different outcomes of combination therapy. objectives the aim of this study was to develop an artificial neural network (ann) model to predetermine individual responses to therapy based on patient’s dem...

fusion of two genes at dna level produces a single protein, known as a chimeric protein. immunotoxins are chimeric proteins composed of specific cell targeting and cell killing moieties. bacterial or plant toxins are commonly used as the killing moieties of the chimeric immunotoxins. in this investigation, the catalytic domain of shiga-like toxin (a1) was fused to human granulocyte macrophage c...

spinal muscular atrophy (sma) is an autosomal recessive neuromuscular disorder caused by homozygous deletion of the survival motor neuron gene 1 (smn1) in more than 90% of patients. according to the age of onset and severity of the disease, sma is classified into three groups: type i (severe), type ii (intermediate) and type iii (mild). as reported, the smn2 gene, centromeric copy gene, showed ...

the molecular dynamics (md) simulation method is used to assess structural details for humanprion protein (hereafter prpn) and its asp178 asn mutant (hereafter prpm) which causes fatalfamilial insomnia disease. the results reveal that the flexibility and instability increase in prpmcould be related to specific amino acids exposed to the solvent. solvation free energy of prpm is 20kjmot1nni2 mor...

background: silicosis is known in industrial workers for centuries. till recently, the mainstay of its diagnosis and progress was clinical examination of the respiratory system, pulmonary function test and chest radiography. several biomarkers such as serum angiotensin converting enzyme (ace) activity have been examined to determine the extent of silicosis. objective: to elucidate the effect of...

Selection of a system for successful recombinant protein production is important. The aim of this study wasto produce high levels of human interleukin-2 (hIL-2) in soluble form. To this end, the pET32a vector inEscherichia coli BL21 (DE3) was used as an expression system, since it was previously used for the productionof mouse IL-2 in soluble form. The results indicated that c...
