Total RNA was isolated together with the RNeasy Mini Kit (Qiagen) in line with the manufacturer’s protocol. Complementary DNA was synthesized from 1 mg total RNA, making use of a Transcriptor 1st Strand cDNA Synthesis Kit (Roche) within the presence of both oligo (dT) and random primers. The sequences of all PCR primers are listed in Supplementary Table 2. The relative expression level of every single target gene was determined making use of the comparative threshold cycle (Ct) method and normalized to respective GAPDH controls. Engineering Dox-inducible plasmids and steady cell lines. The full-length cDNA of TLK2 was bought from Origene (Catalogue #: SC115810), and also the open reading frame (ORF) was subcloned into an inducible lentiviral pTINDLE vector provided by Dr Xuewen Pan. This vector includes an inducible promoter (pTRE-tight) as well as a transactivator (rtTA3) inside a lentiviral backbone. We also engineered the ORF of Yellow Fluorescent Protein (YFP) in to the pTINDLE vector as a handle. TLK2 shRNA (50 -CCCAGAATAGTTAAGCTGT-30 ) and non-silencing controls (50 -ATCTCGCTTGGGCGAGAGTAAG-30 ) were purchased from Open Biosystems. The shRNA was engineered into another inducible lentiviral pINDUCER vector50. Soon after lentivirus packaging, cells were infected by lentivirus containing doxycycline (Dox) inducible plasmid,.
