The ATP synthase in mitochondria was responsible for the synthesis of to provide chemical energy cell achieve metabolism. point mutation at mitochondrial DNA nt 8993(T>C and T>G) disrupted normal cellular mechanism synthase, causing a deficiency production synthesis. 8993 causes replacement leucine amino acid with an arginine(aL156R), changing sequence ATP6 gene, which inefficiency c-subu...

Abstract Denis Noble convincingly describes the artifacts of theory building in Modern Synthesis as having been surpassed by available evidence, indicating more active and less gene-centric evolutionary processes than previously thought. We diagnosis failure holders to dutifully update their beliefs according new findings a microcosm prevailing larger social inability deal with competing paradi...

The fat content of milk determines the quality milk, and triglycerides are major components fat. Milk synthesis is regulated by many factors. Lipopolysaccharide (LPS) has been shown to inhibit in bovine mammary epithelial cells, but research on underlying mechanisms limited. MicroRNA (miRNA) involved physiological processes, there have few studies their regulation synthesis. In this study, we a...

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...

background and objectives: baculovirus can be used as a vector in gene delivery system. viral envelope of baculovirus would display expressed protein/peptide and it could render as a potential vaccine delivery system. in this regard, the gene coding for a subunit of shiga toxin (stxa) from escherichia coli ( e. coli ) strain was cloned in a baculovirus expression system. stxa subunit has the ab...

background and aim: colon cancer is the third most prevalent cancer in iran. prolonged colon inflammation is an important factor, in the development of colon cancer. ginger has anti-inflammatory properties due to its content of [6]-gingerol and hence can play a role in the prevention of colon cancer. in this research the effects of ginger extract on reducing expression of the cox-2 gene in ht-2...

Ongoing protein synthesis is a prerequisite in the expression of some genes. We studied the effect of various protein synthesis inhibitors on the expression of the avian metallothionein (MT) gene. Chicken embryonic hepatocytes in culture were exposed to various concentrations of cycloheximide, puromycin and pactamycin. At concentrations which decreased total protein synthesis by about 90% each ...
