The Cas9 endonuclease can be targeted to genomic sequences by programming the sequence of an associated single guide RNA (sgRNA). For unknown reasons, the activity of these Cas9-sgRNA combinations varies widely at different genomic loci and in different cell types. Thus, disrupting genes in polyploid cell lines or when using poorly performing sgRNAs can require extensive downstream screening to...
Recently, gene editing with transcription activator-like effector nucleases (TALENs) has been used in the life sciences. TALENs can be easily customized to recognize a specific DNA sequence and efficiently introduce double-strand breaks at the targeted genomic locus. Subsequent non-homologous end-joining repair leads to targeted gene disruption by base insertion, deletion, or both. Here, to rea...
Background: Most of colorectal cancers arise from intestinal polyps. Evaluating of the expression level of genes that are involved in tumors growth and development, may consider as diagnostic factor of malignancy in the polyps. Failure of apoptosis is one of the causes of cancers. One of the key molecules in this pathway is Bid gene which connects the extrinsic to the intrinsic apoptosis pathwa...
In H. polymorpha, there is still a lack of a highly efficient gene disruption method. To help address this issue, we presented a simple and efficient method for both single and multiple gene disruptions in H. polymorpha. The knockout system combined a variation of sticky-end polymerase chain reaction method (SEP), split marker deletion method, co-transformation of single-stranded DNA and mutant...
BACKGROUND Production directly from carbon dioxide by engineered cyanobacteria is one of the promising technologies for sustainable future. Previously, we have successfully achieved 1,3-propanediol (1,3-PDO) production using Synechococcus elongatus PCC 7942 with a synthetic metabolic pathway. The strain into which the synthetic metabolic pathway was introduced produced 3.48 mM (0.265 g/L) 1,3-P...
