BRafCA, Tyr::CreER and Ptenlox4-5 mice were genotyped as previously described 17 (link),20 (link),24 (link). Cre-mediated conversion of BRafCA to BRafVE and the deletion of exons 4 and 5 of Pten were assessed by PCR as previously described. Topical administration of 4-hydroxytamoxifen (4-HT) was performed by preparing a 25-50mg/ml (65-130mM) solution of 4-HT (70% Z-isomer, Sigma) in DMSO and applying enough solution to wet the right ear, right flank and tail with a small paint brush on post-natal days 2, 3, and 4. For localized melanoma induction on the back skin, adult (6-8 weeks of age) mice were treated topically with 1-2 μl of 1.9mg/ml (5mM) 4-HT at 6-8 weeks of age using a similar protocol. Generalized induction in adult mice was performed by intra-peritoneal injection of 1mg of tamoxifen/40g mouse on 3 consecutive days. In this case tamoxifen was prepared as a 10mg/ml suspension in peanut oil. PD352901 was dissolved in 0.5%(w/v) Hydroxy-propyl-methylcellulose, 0.2%(v/v) Tween 80 (Sigma) and administered to mice daily by oral gavage at a dose of 12.5mg/kg. Rapamycin (LC Laboratories, Woburn, MA) was suspended in 0.5%(w/v) methylcellulose and administered to mice daily by oral gavage at a dose of 7.5mg/kg. Control animals in the melanoma prevention studies were administered with the relevant solvent. Tissues were prepared for analysis as previously described 17 (link),20 (link)

Monocytes trafficking into primary tumors and their metastases were studied by adoptive transfer of mouse (Ly6C/Gr1+ or Ly6C/Gr1−) or human (CD14+CD16+ and CD16−) monocytes using MMTV-PyMT autochthonous, human and mouse experimental metastasis and human orthotopic tumor models. Monocytes and macrophages were recovered by enzymatic disaggregation of the tumors followed by FACS analysis. To test mechanisms behind monocyte recruitment and the effect of inhibition of this trafficking on metastasis anti-mouse or human neutralizing CCL2 antibodies or Ccr2 null mutant mice were used. In order to ablate VEGF expression in monocytes a myeloid specific (Csf1r promoter) tamoxifen inducible Cre expressing strain was crossed with VEGFflox/flox mice and gene ablation induced by tamoxifen. Effects of monocyte depletion on tumor cell extravasation using Met-1, a FVB PyMT tumor derived metastatic cell line, was determined using an ex vivo intact lung imaging system and an in vitro extravasation assay.

The Bmi1CreER; RosatdTomato mice received drinking water with 4NQO for 16 weeks to allow HNSCC to develop, followed by normal drinking water for 6 weeks, to form a spontaneous model of HNSCC. The mice were randomly divided into groups at 22 weeks. Before sacrificing the mice, they were given tamoxifen to label Bmi1+ CSCs. For the treatment assay, Bmi1CreER; RosatdTomato mice were divided randomly into the indicated groups, and injected with the indicated ASO PVT1 (10 nM, Integrated Biotech Solutions Co., Ltd, Shanghai, China) and ASO NC over the whole mouse tongue by twice-weekly subcutaneous injection for 4 weeks. For combination therapy, mice were intraperitoneally injected with anti-PD1 (BioXcell, Lebanon, NH, USA, 200 μg/mouse twice per week). After mice were sacrificed, the cervical lymph nodes and tongues were removed, and the lesion surface areas were calculated. For histological investigation and immunostaining, longitudinally cut tongues (dorsal/ventral) and intact lymph nodes were fixed overnight in 4% paraformaldehyde and paraffin-embedded. 10 sections of 5 mm thick tissue blocks were cut, and they were then stained with hematoxylin and eosin (HE). The SCC number was counted and regions were measured [8 (link)]. The following criteria were used to grade the invasiveness of the HNSCC: showing signs of normal or epithelial dysplasia appearance (grade 1); distinct invasion, unclearness of the basement membrane, drop and diffuse infiltration into the superficial portion of the muscle layer (grade 2); loss of the basement membrane; extensive invasion into deep muscle layer (grade 3). To examine cervical lymph node metastasis of HNSCC, the sections of cervical lymph nodes were immunostained with anti-PCK antibodies.

The effects of αv knockout on gene expression were examined at 6 weeks after tamoxifen injection followed or not by a 4-week treatment with Ang II. Anaesthesia was induced by isoflurane inhalation at 3.5% in 1 L/min oxygen, and then maintained at 1.5% in 1 L/min oxygen during the intervention. Angiotensin II was administered at 1.5 mg/kg/day for 28 days via subcutaneous Alzet osmotic minipumps (Charles River, L’Arbresle, France). Prior to pump implantation, mice were conditioned to tail-cuff blood pressure measurement using a computerized mouse tail-cuff sphygmomanometer (Hatteras Instruments, Inc., NC, USA). Systolic arterial pressure (SAP) and heart rate (HR) were measured on the day of surgery and on day 28 prior to euthanasia. Mice were euthanized via exsanguination under isoflurane anaesthesia (1.5% in 1 L/min oxygen). Carotid arteries were used for morphological and histological analyses and thoracic aorta for all other parameters. It is generally accepted including our previous studies that changes in gene and/or protein expression are similar in these two main conductance arteries.14 (link),15 (link)

SM22-CreERT2(ki) transgenic mice have been described previously.12 (link)Itgavflox/flox mice were obtained from A. Lacy-Hulbert13 (link) and maintained on a C57BL/6 background. Itgavflox/flox mice were crossed with SM22-CreERT2(ki) mice to generate SM22-CreERT2(ki)/Itgavflox/flox double-transgenic mice. All mice (male and female) were genotyped by PCR as described previously.12 (link),13 (link) At 8–10 months of age, Itgavflox/flox/SM22-CreERT2(ki)/+ mice were injected intraperitoneally with 1 mg of tamoxifen in 100 µL of peanut oil for 3 days to generate αvSMKO mice. Itgavflox/flox littermates injected for 3 days with tamoxifen were used as controls. All experiments were performed 4–6 weeks after tamoxifen injection. Mice were housed in a temperature- and humidity-controlled facility with a 12 h light/day cycle and given free access to standard rodent chow and water. All animal work was conducted in accordance with French regulations and experimental guidelines of the European Community, and the protocols were approved by the local Animal Ethics Committee of the University of Lorraine, France.

For auditory stimulation, mice at P16–P30 were housed in a custom soundproof box, and received sound stimulation as illustrated in Figure 1A . After three quiet hours, continuous sound was delivered for 6 h at ∼90 dB using BioSigRP software (Tucker-Davis Technologies). A 15-kHz tone of 20-ms duration with 2-ms rise and fall time was presented at a rate of 41 Hz (leaving 4.4-ms gaps). The sound was produced by a PC sound card, processed by RZ6 Multi-I/O Processer (Tucker-Davis Technologies), and delivered via a speaker (Ignite) mounted directly above the animals. The sound was paused for no more than 5 min after the first 3 h to administer an intraperitoneal injection of 160 mg/kg Tamoxifen or 50 mg/kg 4-OHT. Tamoxifen was first dissolved in absolute EtOH, then diluted 1/10 by volume with sunflower oil followed by 2-h sonication or overnight nutation, and stored at 4°C in the dark for up to one week. 4-OHT was first dissolved in absolute EtOH at 20 mg/ml, and diluted with Chen oil (a 1:4 mixture of castor oil:sunflower seed oil) to 10 mg/ml for injection (Guenthner et al., 2013 (link)). After sound stimulation, mice were kept in quiet for another 3 h before returning to their home cage, and killed 4–5 d later for experiments. This protocol has been shown to produce tonotopic labeling in DCN and VCN from TRAP mice crossed with the Ai14 reporter line (Guenthner et al., 2013 (link)). The time line is consistent with the time window determined by the pharmacodynamics of 4-OHT in mice (Robinson et al., 1991 (link)).

Adoptive transfers were performed by intravenous injection of 5 × 103 Igλ-enriched B1-8 B cells into the retro-orbital plexus of anesthetized mice. Mice were immunized the following day. All immunizations were performed using NP-CGG (Biosearch Technologies) resuspended at 1 mg/ml in D-PBS and mixed 50:50 volumetrically with Alhydrogel (Accurate Chemical and Scientific). Mice were injected subcutaneously with 20 μl of this solution (10 μg of NP-CGG per injection) in each ear. At endpoint, the facial LNs from each side were pooled for analysis (see figure legends for various timepoints).
Unmodified αIgE (clone R1E4; produced by hybridoma culture as described below), αIgE with a mutated Fc-receptor binding domain (clone R1E4; Cedarlane), or control rat γ globulin were diluted in D-PBS to a concentration of 0.3 mg/ml and injected intravenously to achieve a final dose of 3.25 mg/kg. For the experiment shown, mouse γ globulin (Jackson ImmunoResearch) was used as a control whereas in previous experiments that the presented data are representative of rat γ globulin was used as a control.
Tamoxifen was dissolved at 50 mg/ml in corn oil (Sigma-Aldrich) by shaking at 56°C for several hours. Approximately 100 μl/mouse was delivered by intraperitoneal injection to achieve a dose of 200 mg/kg.
