To construct mammalian expression plasmids, the respective genes of FPs were PCR-amplified as AgeI-NotI fragments and swapped with a gene encoding EGFP in the pEGFP-N1 plasmid (Clontech). IFP2.0-N1 and mIFP-N1 plasmids were acquired from Addgene (#54785 and #54620, respectively).
For protein tagging and labelling of intracellular structures study, miRFPs were amplified, digested with restriction enzymes and then swapped with mTagBFP2 either as C- (for α-tubulin and clathrin) or N-terminal fusions (for keratin, α-actinin, LifeAct, EB3, myosin, vimentin, clathrin, LAMP1, zyxin, H2B and mitochondrial signal) as previously described50 (link). C-terminal fusions (SGGGG)n linker was increased to 30 amino acids. N-terminal fusions linker length was left unchanged.
To create an IκBα reporter plasmid (CMV-IκBα-miRFP703), we used a CMV-IκBα-FLuc plasmid kindly provided by S. Achilefu and D. Piwnica-Worms. A FLuc gene was replaced with one of the miRFP genes. Kozak sequence was deleted in the CMV-IκBα-miRFP703 and CMV-miRFP control plasmids.
miSplit670 and miSplit709 reporter plasmids, which are pC4-RHE-PAS, pC4EN-F1-mGAF670 and pC4EN-F1-mGAF709, were constructed from an iSplit plasmids25 (link) by swapping either PAS or GAF domains. A linker -ggggsggggs- was left unchanged. Where appropriate, an NLS sequence in the pC4EN-F1 plasmid was deleted by site-directed mutagenesis.
For mRNA labelling, a CMV-PAS-MCP plasmid was constructed as follows. PAS-ggggsggggs- without STOP codon was amplified as a single fragment and inserted into the C1 vector backbone using AgeI and KpnI sites, MCP was amplified from an ubc-nls-ha-MCP-VenusN-nls-ha-PCP-VenusC plasmid (Addgene, #52985) and inserted at KpnI and BamHI sites. The cmv-PCP-mGAF670 and cmv-PCP-mGAF709 plasmids were constructed as follows. A PCP without STOP codon was amplified from an ubc-nls-ha-MCP-VenusN-nls-ha-PCP-VenusC plasmid and then inserted into the C1 vector backbone using AgeI and EcoRI restriction sites. A -ggggsggggs-miGAF was amplified as a single fragment and inserted using EcoRI and KpnI sites. A phage-cmv-cfp-12xMBS-PBS was obtained by swapping a 12xMBS-PBS fragment from a Pcr4-12xMBS-PBS (Addgene, #52984) with 24xMS2 in a phage-cmv-cfp-24xms2 plasmid (Addgene, #40651). An ubc-nls-ha-MCP-VenusN-nls-ha-PCP-VenusC, a phage-cmv-cfp-24xMS2 and a Pcr4-12xMBS-PBS plasmids were gifts from B. Wu and R. Singer.
Plasmids encoding several green-red Fucci cell cycle reporters were provided by A. Miyawaki. The mKO2 and mAG genes fused with hCdt1(30–120), hCdt1(1/100), hGem(1/110) and hGem(1/60) sequences in the pCSII-EF-MCS plasmids were swapped with the miRFP709 or miRFP670v1 genes.

Cells and tissues were lysed in RIPA buffer. Tumors were ground in liquid nitrogen and lysed. Protein concentration was determined using the BCA Kit (Beyotime Institute of Biotechnology). Proteins were mixed with loading buffer and heated at 70°C for 10 minutes on sodium dodecyl sulfate (SDS)-polyacrylamide gels at 30 μg per lane. The proteins were transferred to polyvinylidene fluoride (PVDF, Millipore, MA, USA) after electrophoresis. Membranes were blocked for 2 hours in 5% BSA and incubated overnight at 4°C with antibodies against γ-H2AX, ATM, ATR, Chk1, cell-cycle controller-2 (Cdc2), E-cadherin, vimentin, caspase-3, and caveolin-1 (Cav-1). The blots were then incubated with HRP-conjugated secondary antibody (1:1000; Santa Cruz Biotechnology). Finally, bands were visualized by enhanced chemiluminescence (Thermo Scientific Pierce, IL, USA).

Eighteen samples (10 samples from NSCLC patients and 8 samples from breast cancer patients) were used to compare the efficacy of the CanPatrol CTC enrichment technique before and after optimization. For each sample, 5 ml of blood was used for CTC isolation and characterization using each method. Before optimization, a combination of the CD45+ magnetic bead separation and filtration methods was used for CTC isolation, and an immunostaining method was applied for CTC characterization. The protocol of this method has been described before [23 ]. To classify CTCs using EMT biomarkers, an antibody cocktail consisting of anti-EpCAM (R&D, Minneapolis, USA), anti-CK8/18/19 (R&D, Minneapolis, USA), anti-vimentin (BD Bioscience, San Jose, USA), anti-twist (BD Bioscience, San Jose, USA) and anti-CD45 (Surexam, Guangzhou, China) was used to stain the CTCs.

After preprocessing, we segmented all major tissue components. Images were converted into binary images by applying histogram-based threshold. For this purpose, the mode and standard deviation (σ) were determined for each channel of an image stack. Threshold levels were set to mode+σ for the WGA channel and mode+2σ for the DAPI, vimentin and α-SMA channels. We used a lower weighting factor for σ to threshold WGA channels because the high ratio of voxels with WGA signal (≥ 20%) led to a relatively higher standard deviation versus other channels. Images were then filtered with a binary median filter (radius 1). The segmented WGA signal was used to segment each cardiomyocyte by means of a watershed-based method as described previously.34 This method created labeled segments for each volume enclosed by WGA signal. At first, we identified myocytes. Subsequently, vessel lumens were identified within the non-myocyte segments. Vessel lumens were then dilated with a radius of 1 μm to include the vessel walls and endothelium. Possible overlap with the myocyte space was subtracted after the dilation. Cardiomyocyte and vessel volumes were then subtracted from the segmented WGA, DAPI, vimentin and α-SMA volumes. The remaining DAPI was identified as non-cardiomyocyte nuclei and merged with the remaining vimentin and α-SMA volumes. Using distance maps, we classified voxels of the merged volume closer to vimentin than to α-SMA as fibroblasts, while other voxels were classified as myofibroblasts. Finally, remaining non-classified segments from the watershed algorithm were merged with the remaining WGA volume and classified as extracellular space.
We determined volume ratios of all tissue components. Also, we calculated the number of neighboring myocytes by selecting complete cardiomyocytes, which were not truncated at image borders. We generated distance maps from the complete myocytes and then identified and counted all myocytes within a distance of 0.5 μm to the outer sarcolemma.
For 2D visualizations of images we used customized software. For 3D visualizations we applied Paraview (Kitware, Clifton Park, New York, USA), VolView (Kitware) and customized software.

Given the effect of the overexpression of the SEQ ID NO:1, further experiments were performed to study its effect in cell invasion, another key oncogenic trait. Boyden chamber assay was used to determine invasiveness of A549 and H10 cancer cells after 4 days of doxycycline induction of SEQ ID NO:1, showing that the expression of the micropeptide induces a significant decrease in invasion (FIGS. 9A and B). In line with this observation, overexpression of the micropeptide of SEQ ID NO: 1 represses the expression of the EMT regulators VIMENTIN, SLUG, SNAIL, N-CADHERIN, TWIST1, TWIST2, ZEB1 and ZEB2 in H10 SCC cell line (FIG. 9C). This downregulation of the mesenchymal program further validates the role of the micropeptide of SEQ ID NO: 1 as a tumor suppressor.

Fig. S1 shows that Prdm16 is transiently expressed in the premalignant lesions. Fig. S2 shows that Prdm16KO mice display normal insulin and glucagon expression and distribution as well as normal blood glucose levels. Fig. S3 provides additional data demonstrating that inactivation of Prdm16 accelerates KrasG12D-driven PDAC. Fig. S4 displays that Prdm16 is required for IPMN-to-PDAC progression and that Prdm16 deletion led to the accumulation of cells with high vimentin expression. In addition, Fig. S4 shows the effects of deleting PRDM16 on the proliferation of PANC-1 and BxPC-3 cell lines. Fig. S5 further expands upon the notion that concomitant inactivation of Prdm16 and Smad4 mimics the phenotype of complete TGF-β signaling inactivation through TβRII ablation.

Primary HDSCs were separated from decidual tissues by means of enzymatic dispersion and mechanical dissociation, as mentioned before (Zhu et al., 2007 (link)). Generally, the samples were washed in cold phosphate-buffered saline (Gibco, Life Technologies, Inc., Carlsbad, CA, United States of America) three times, and then minced and treated with 0.1% collagenase (type IV; Sigma‒Aldrich), 0.1% hyaluronidase (type I-S; Sigma‒Aldrich) and 0.5 mg/ml DNase I (Sigma‒Aldrich) and subsequently digested in a shaking water bath for 60 min at 37°C. The supernatant was neutralized by the addition of phenol red-free DMEM/F12 medium supplemented with 10% FBS before the cells were passed through a 40 m nylon filter (BD Biosciences, Bedford, UK). The undigested tissue fragments were left on the filter, and the stromal cell-containing eluate was transferred into a 50 ml tube. The cells were then pelleted by centrifuging them at 1200 g for 3 min at room temperature. Following that, the cell pellets were washed, resuspended, and seeded in phenol red-free DMEM/F12 media with antibiotics (100 U/ml penicillin and 100 μg/ml streptomycin, Life Technologies, Inc.), 10% FBS, 30 nM 17β estradiol (E2; Sigma Aldrich), and 1 μM progesterone (P4; Sigma Aldrich). All decidual stromal cell cultures were afterwards maintained at 37°C in a humid incubator with 5% CO2, unless otherwise stated, in this culture medium. The purity of the HDSCs was determined by immunofluorescent staining for vimentin and cytokeratin-7 as described previously (Zhu et al., 2007 (link)). HDSCs were cultivated at a density of 5 × 105 cells per plate in 60-mm tissue culture dishes for the time- and concentration-dependent studies, and BMP2 was added in the same manner as HESCs.
