De Novo Protein Synthesis in Vitro - ScienceDirect

RNA-editing hypothesis postulates thatactivation-induced cytidine deaminase deaminates cytosine in an unknownmRNA to generate a new mRNA encoding an endonuclease for CSR and thuspredicts that DNA cleavage depends on de novo protein synthesis.

De Novo Protein Synthesis of Syntaxin-1 and ..

There are four different nitrogen bases, adenine, thymine, cytosine and guanine. The synthesis of a particular protein such as insulin is determined by the sequence in which these bases are repeated (see fig.

GeneCopoeia offers de novo gene synthesis services for any genes that are currently not already on our list of pre-made and ready to use ORF cDNA clones. All synthesized genes can be constructed in any of the 150+ expression vectors from the OmicsLink™ ORF cDNA clone collection at no additional fee. A minimum order of 1kb gene or $350 is required.

N2 - Increased expressions of fatty acid synthase (FASN) and epidermal growth factor receptor (EGFR) are common in cancer cells. De novo synthesis of palmitate by FASN is critical for the survival of cancer cells via mechanisms independent of its role as an energy substrate. Besides the plasma membrane and the nucleus, EGFR can also localize at the mitochondria; however, signals that can activate mitochondrial EGFR (mtEGFR) and the functions of mtEGFR of cancer cells remain unknown. The present study characterizes mtEGFR in the mitochondria of cancer cells (prostate and breast) and reveals that mtEGFR can promote mitochondrial fusion through increasing the protein levels of fusion proteins PHB2 and OPA1. Activation of plasma membranous EGFR (pmEGFR) stimulates the de novo synthesis of palmitate through activation of FASN and ATP-citrate lyase (ACLy). In vitro kinase assay with isolated mitochondria shows that palmitate can activate mtEGFR. Inhibition of FASN blocks the mtEGFR phosphorylation and palmitoylation induced by EGF. Mutational studies show that the cysteine 797 is important for mtEGFR activation and palmitoylation. Inhibition of FASN can block EGF induced mitochondrial fusion and increased the sensitivity of prostate cancer cells to EGFR tyrosine kinase inhibitor. In conclusion, these results suggest that mtEGFR can be activated by pmEGFR through de novo synthesized palmitate to promote mitochondrial fusion and survival of cancer cells. This mechanism may serve as a novel target to improve EGFR-based cancer therapy.
