The pellet was resuspended in 20ml FACS buffer and strained through a 70m cell strainer (BDBiosciences). As judged by this assay, most tumour growth attributable to mTOR signalling operates through LEPR. Leptin normally circulates through the bloodstream, which we corroborated by enzyme-linked immunosorbent assays (ELISAs) of blood plasma from non-tumour bearing control mice. Biol. Langmead, B. led the development of StringTie and J.T.L. & Tumbar, T. Defining a tissue stem cell-driven Runx1/Stat3 signalling axis in epithelial cancer. Next, all peaks from IFE, HFSC, PAPneg, PAPpos, SCCneg and SCCpos were concatenated to a union peak set, and the read coverage of each sample at these peaks was calculated with Bedtools (v.2.25). Owing to multiple targeted proteins in each experiment, one set of identical samples with the same sample volumes and processing procedure was blotted for GAPDH or -tubulin in one of the gels in the same experiment as a loading control.

In brief, a recombinant Cas9 protein, validated sgRNA (GAGUCAUCGGUUGUGUUCGG) targeting exon 3 of the mouse Lepr gene or a negative control sgRNA (IDT), and an ATTO-550-conjugated tracer RNA were used to form a ribonucleoprotein (RNP) were mixed with RNAiMax reagent (Thermo Fisher Scientific). A total of 100l of lysates and standards in duplicates were loaded into 96-well black assay plate (Thermo Fisher Scientific) and then read at an excitation of 680nm and emission of 695nm. d, Transcript levels of Itga6, Itgb1 and Cd44 are increased from normal skin to papilloma and SCC. The genes in this cascade are often found mutated in cancers, but as shown here, can be driven by interactions between CSCs and their tumour microenvironment. Scheitz, C. J., Lee, T. S., McDermitt, D. J. The output table is ordered by 4a). Thus, through the ability of oncogenic RAS to reroute the stem cells communication circuitry with its surrounding microenvironment, and the ability of the microenvironment in turn to induce a membrane receptor on the stem cells, CSCs exploit this dynamic crosstalk, fuelling non-genetic circuitries that drive malignant progression (Extended Data Fig. & Greenleaf, W.

The distribution and changes in cancer stem cells during progression from a benign state to invasive squamous cell carcinoma remain unclear. To compare the tumour-initiating ability between Leprnull PDVC57 and Leprctrl PDVC57 cell lines, a preset number of cells were intradermally grafted onto Nude mice, and the tumour growth was tracked for 5weeks to calculate the tumorigenicity of cells. Ritchie, M.E. The other authors declare no competing interests. 36, 839842 (2018). For the phosphorylated protein flow cytometry experiment, single-cell suspensions were obtained from papilloma or SCC tumour tissues as described above.
