background: protozoa related to trypanosome family including leishmania , synthesize enzymes to escape from drug therapy. one of them is ptr1 that its enzymatic activity is similar to dihydrofolate reductase (dhfr). dihydrofolate reductase - thymidylate synthase has a major role in dna synthesis, if it is inhibited, the result would be the death of parasite. since ptr1 activity is similar to dh...
objectives the cause of rheumatoid arthritis (ra) as a chronic inflammatory autoimmune disease is still unknown. it appears that both genetic and environmental factors play a role in its pathogenesis. recent studies reveal that in addition to the cns, immune cells synthesis neurotransmitters so that these catecholamines can regulate immune functions. the aim of this study is to evaluate the dop...
context:micrornas (mirnas) are a class of short, endogenously-initiated, non-coding rnas that post-transcriptionally control gene expression via translational repression or mrna turnover. mirnas have attracted much attention in recent years as they play critical roles in gene expression and are promising tools with many biotech and therapeutic applications. the molecular mechanisms underlying t...
objective: diacylglycerol acyltransferase 1 is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. the objective of this project is to check out the polymorphism at the exon 8 region of dgat1 gene using pcr-sscp technique in iranian water buffaloes (bubalus bubalis). recent activities have shown that a significant association between lysine at amino acid position 232 wi...
Large DNA constructs of arbitrary sequences can currently be assembled with relative ease by joining short synthetic oligodeoxynucleotides (oligonucleotides). The ability to mass produce these synthetic genes readily will have a significant impact on research in biology and medicine. Presently, high-throughput gene synthesis is unlikely, due to the limits of oligonucleotide synthesis. We descri...
Background: As the third most frequent cause of cancer death, breast cancer is a common disease worldwide. Most of the patients are being diagnosed in the stage that conventional treatments are not effective, and invasion and metastases lead to death. Therefore, identification of novel molecular markers to improve early diagnosis, prognosis and treatment of the breast cancer is a necessity. Zin...
Skin aging is a biological process that is due to the reduction of collagen production and increase of multiple enzymes, including matrix metalloproteinase (MMPS), which degrade collagen. Chlorella vulgaris is a marine microalga and its beneficial effects on the skin make it a proper ingredient to be used in anti-aging products. In this study, the effect of C. vulgaris extract comparing to vita...
Background Beta thalassemiais a genetic blood abnormality identified through mutations, which reduce the synthesis of the ß-globin chain. Gene therapy through Lentiviral vectors have cured many of genetic disorders. The purpose of this study was to investigate the efficacy of lentiviral vectors in treatment of ß-thalassemia a...
Histone proteins are key elements in the packing of eukaryotic DNA into chromosomes. A little understood control system ensures that histone gene expression is balanced with DNA replication so that histone proteins are produced in appropriate amounts. Disturbing or disrupting this system affects genome stability and gene expression, and has detrimental consequences for human development and hea...
Gene synthesis, the process of assembling gene-length fragments from shorter groups of oligonucleotides (oligos), is becoming an increasingly important tool in molecular and synthetic biology. The length, quality and cost of gene synthesis are limited by errors produced during oligo synthesis and subsequent assembly. Enzymatic error correction methods are cost-effective means to ameliorate erro...
