Tissue arrays of formalin-fixed tissues from human head and neck squamous cell carcinoma (HN803) were retrieved from Biomax US (Rockville, MD, USA). Clinical data, including pathological classification and TNM classification, were provided by Biomax. These tissue microarray slides included 57 confirmed cases of HNSCC, 10 cases of normal tongue mucosa, and 4 cases of lymph node metastasis in HNSCC tissue. Immunohistochemistry for Tgfbr1 (1:100), p-S6 (S235/236, 1:200), and Survivin (1:400) was stained in serial-cut tissue array sections.

Mouse genotyping was performed by PCR of the tail DNA. For genotyping Cre-deleted flox survivin allele, three primers, Adv17, Adv25, and Adv28, were used for PCR. For the survivin flox allele, a fragment of 577 bp was generated with the pair of primers Adv25 and Adv 28 as described above. For the deleted allele, a fragment of 420 bp was generated with primers Adv17 and Adv28 (see Fig. 1, A, C, and D ). Genotyping of survivin+/− mice has been described (37 (link)).

Immunofluorescence, immunoblotting, and immunoprecipitations were all done as described previously (Taylor et al., 2001 (link)) using antibodies against the following: phosphohistone H3 (Upstate Biotechnology); cyclin B1 (Upstate Biotechnology); tubulin (TAT1); centromere/kinetochores (human ACA); BubR1 (SBR1.1); Bub1 (4B12); Aurora A (RAA.1); and Myc-tag (9E10). Aurora B was detected using either the anti-AIM-1 mouse mAb (Transduction Laboratories) or a sheep anti–human Aurora B pAb (unpublished data). For localization of Mad2 and Survivin, we used DLD-1 cell lines stably expressing Myc-tagged hMad2 or hSurvivin ORFs (unpublished data). For IP kinase assays, beads were equilibrated in kinase buffer (10 mM Tris, pH7.5, 5 mM KCl, 1 mM NaF, 0.24 mM DTT, and 2.5 mM MnCl) and were then incubated at RT for 1 h in kinase buffer supplemented with 2.5 μM ATP, 5 μCi γ[32P]ATP, and 3 μM biotinyl-Ahx-tetra (LRRWSLG) peptide substrate. Reactions were stopped with 20% phosphoric acid, and were then spotted onto P30 filtermat (Whatman). After five washes in 0.5% phosphoric acid, bound radiolabel was quantitated by scintillation counting. Deconvolution microscopy and pixel intensity quantitation were performed as described previously (Taylor et al., 2001 (link)). In brief, kinetochore fluorescence values were determined using softWoRx imaging software (Applied Precision). Background readings were subtracted, and the values were then normalized against the ACA signal to account for any variations in staining or image acquisition. SoftWoRx was used to measure interkinetochore distances using either ACA or Bub1 foci as indicated to determine kinetochore position.

Total RNA from control or PPRH-transfected cells for 24 h and 48 h was extracted using Trizol Reagent (Life Technologies, Madrid, Spain), following the instructions of the manufacturer. Complementary DNA was synthesized in a 20 µL reaction mixture from 1 µg of total RNA, 0.5 mM of each deoxyribonucleotide triphosphate (dNTP, Epicentre, Madison, USA), 250 ng of random hexamers (Roche, Barcelona, Spain), 10 mM dithiothreitol, 200 units of a Moloney murine leukemia virus reverse transcriptase (RT), 20 units of RNase inhibitor, and 4 µL of buffer (5×) (all three from Lucigen, Middleton, WI, USA). The reaction was incubated at 42 °C for 1 h.
The BIRC5 mRNA TaqMan probe (Hs04194392_s1; ThermoFisher Scientific, Madrid, Spain) was used to determine survivin mRNA levels and the Cyclophilin (PP1A) mRNA TaqMan probe (Hs04194521_s1, ThermoFisher Scientific, Madrid, Spain) was used as the endogenous control. The reaction was conducted in 20 μL containing 1xTaqMan Universal PCR Mastermix (Applied Biosystems, Madrid, Spain), 0.5xTaqMan probe, and 3 μL of cDNA. PCR cycling conditions were 10 min denaturation at 95 °C, followed by 40 cycles of 15 s at 95 °C, and 1 min at 60 °C using a QuantStudio 3 Real-Time PCR System (Applied Biosystems, Barcelona, Spain). The quantification was performed using the ΔΔCt method, where Ct is the threshold cycle that corresponds to the cycle when the amount of amplified mRNA reaches the fluorescence threshold.

The search for polypurine sequences to design PPRHs from was performed with the triplex-forming oligonucleotide target sequence search software (http://utw10685.utweb.utexas.edu/tfo/ , accessed on 22 December 2022, MD Anderson cancer center, The University of Texas) [32 (link)]. The PPRH (HpsPr-C) against the survivin gene, which was directed to the promoter sequence, was used for gene silencing experiments and was previously validated in our laboratory [15 (link),19 (link)]. The design of the hairpin consisted of two antiparallel mirror repeats of polypurine sequences bound by intramolecular reverse Hoogsteen bonds and linked by a thymidine loop (4–5 Ts). The same PPRH against survivin was also synthesized with a fluorescence label (FAM-HpsPr-C) in its 5′-end. The negative control was an unspecific scrambled hairpin (HpScr9) that could not form a triplex with the target DNA.
Hairpins used in the study were synthesized as nonmodified oligodeoxynucleotides by Merck (Haverhill, UK). They were resuspended in a sterile Tris–EDTA buffer (1 mM EDTA and 10 mM Tris, pH 8.0) (Merck, Madrid, Spain) and stored at −20 °C. The hairpin sequences are shown inTable 1 .
The PPRHs designed using the TFO searching tool are shown inFigure 1 . The two sequences run in an antiparallel fashion bound by Hoogsteen bonds and linked by a thymidine loop.
