Hypoxia inducible factor HIF 1 promotes myeloid derived suppressor cells accumulation through ENTPD2/CD39L1 in hepatocellular carcinoma

Nat Commun
PMCID: 5593860
PMID: 28894087
DOI: 10.1038/s41467-017-00530-7

[…] O plasmids were transfected into HCC cells and selected with puromycin for 7–14 days. HIF-1α-stable KO HCC cell lines were established by TALEN approach. HIF-1α-specific TALE domains were designed by E-TALEN software, assembled and cloned into pTALEN v2 vector by “TALE Toolbox”. HIF-1α KO construct was transfected into MHCC97L HCC cells, respectively. Stable cells were clonally expanded. Frame-shi […]


TALEN based HPV E7 editing triggers necrotic cell death in cervical cancer cells

Sci Rep
PMCID: 5511212
PMID: 28710417
DOI: 10.1038/s41598-017-05696-0

[…] Cervical cancer is one of the most common cancers in women worldwide and in more than 90% of the cases HPV has been found as the principal etiological agent. We therefore found it relevant to use TALEN-based genome editing tool, to disrupt viral genes in the genome, as an alternate therapeutic approach. TALEN targeting E7 showed good activity in our study. Our results showed nearly 10% editi […]


TALEN based generation of a cynomolgus monkey disease model for human microcephaly

Cell Res
PMCID: 5034111
PMID: 27502025
DOI: 10.1038/cr.2016.93
call_split See protocol

[…] TALEN target sites were designed and constructed according to the instruction provided with the e-TALEN kit (Viewsolid Biotech). Briefly, units were assembled to construct the TALE repeats according to the target sequences, using several rounds of digestion/ligation. The constructed repetitive T […]


Improvement of Ethanol Production in Saccharomyces cerevisiae by High Efficient Disruption of the ADH2 Gene Using a Novel Recombinant TALEN Vector

Front Microbiol
PMCID: 4939295
PMID: 27462304
DOI: 10.3389/fmicb.2016.01067

[…] Primers F1 and R1 were used to obtain the full sequence of ADH2. The 17 bp target sequence of AGTTGGAGCATAAGGAT in ADH2 was selected using E-TALEN. The left and right arms of sequence-specific TALENs (Ptalen L48 and Ptalen R36) targeting 17 bp sequences adjacent to AGTTGGAGCATAAGGAT were constructed through one-step ligation using the Fa […]


Nuclease Target Site Selection for Maximizing On target Activity and Minimizing Off target Effects in Genome Editing

PMCID: 4786925
PMID: 26750397
DOI: 10.1038/mt.2016.1

[…] many potential target sites.,,,,, Despite the ability of well-designed nucleases to target defined loci with high efficiency, the widespread use of TALENs has been hampered by poor performance of some TALEN pairs designed, thereby necessitating the screening of a large number of candidates to find a validated TALEN pair with a high level of activity. For example, a high-throughput study that look […]


TALEN Based Mutagenesis of Lipoxygenase LOX3 Enhances the Storage Tolerance of Rice (Oryza sativa) Seeds

PLoS One
PMCID: 4671593
PMID: 26641666
DOI: 10.1371/journal.pone.0143877

[…] ous genes were constructed through Golden Gate assembly. The plasmids for TALEN assembly were obtained from www.Addgene.org. The LIC method was modified to allow the incorporation of DNA fragments (i.e., TALEN cassettes) into the destination vectors []. Briefly, a reaction mixture was prepared on ice in a 20 μl volume containing a DNA fragment (400–500 ng), 1×NEB2 buffer (NEB), 0.1 mg/ml BSA (NEB) […]
