Cooption of heat shock regulatory system for anhydrobiosis in the sleeping chironomid Polypedilum vanderplanki

Proc Natl Acad Sci U S A
PMCID: 5877948
PMID: 29463761
DOI: 10.1073/pnas.1719493115
call_split See protocol

[…] Hsf gene siRNAs were designed using siDirect (). The uniqueness of each candidate siRNA was confirmed by BLAST search of the P. vanderplanki genome (MidgeBase: to minimize off-target effects. All d […]


Epirubicin suppresses proliferative and metastatic potential by downregulating transforming growth factor‐β‐induced expression in urothelial carcinoma

Cancer Sci
PMCID: 5891197
PMID: 28940965
DOI: 10.1111/cas.13403

[…] All siRNA oligonucleotide sequences were designed using siDirect software and the oligonucleotide sets used in this study are shown in Table . UC cells were incubated with complete medium until confluence reached 50%‐60%, then UC cells were transfected wit […]


miR 429 suppresses tumor migration and invasion by targeting CRKL in hepatocellular carcinoma via inhibiting Raf/MEK/ERK pathway and epithelial mesenchymal transition

Sci Rep
PMCID: 5799248
PMID: 29403024
DOI: 10.1038/s41598-018-20258-8

[…] CGAGTG-3′ and 5′-GCGCGGCCGCCGGCTGATGCAAG-3′ were for psiCHECK-2-CRKL-3′-UTR-MUT2.For CRKL knockdown, targeting shRNAs were designed according to CRKL sequence (Genbank: NM_005207.3) using Invitrogen, siDirect and Whitehead software. Out of three CRKL-specific shRNA double-stranded oligodeoxyribonucleotides, the optimal shRNA for CRKL knockdown was with the sense and antisense sequences of 5′-GTCAC […]


The pivotal role of aristaless in development and evolution of diverse antennal morphologies in moths and butterflies

BMC Evol Biol
PMCID: 5785806
PMID: 29370752
DOI: 10.1186/s12862-018-1124-2

[…] siRNAs were designed using siDirect version 2.0 [] (Additional file : Table S2), and chemically synthesized and annealed (Fasmac, Atsugi, Japan). The electroporation-mediated RNAi was conducted as described previously []. In br […]


TUFT1 interacts with RABGAP1 and regulates mTORC1 signaling

PMCID: 5798889
PMID: 29423269
DOI: 10.1038/s41421-017-0001-2

Mitochondrial intermediate peptidase is a novel regulator of sirtuin‐3 activation by caloric restriction

PMCID: 5767765
PMID: 29151261
DOI: 10.1002/1873-3468.12914

[…] details of which were published in our previous study .The pMXs‐puro‐mU6 vector was constructed as previously reported . A mouse shRNA against the Mipep (shMipep) expression vector was designed using siDirect 2.0 ( Sequences of oligonucleotides for shMipep and shGFP (used as a negative control) were as follows: shMipep (5′‐GTG ATG AGA AGT TTA TGG GGT TTC AAG AGA ACT CCA […]
