Oncogenic activation of PI3K-AKT-mTOR signaling suppresses ferroptosis via SREBP-mediated lipogenesis. How leptin transits across the vasculature remains unclear25,29, although it is intriguing to speculate that, for solid tumours such as SCCs, mechanical pressures might alter the vascular integrity and facilitate entry of circulating factors such as leptin into the tumour microenvironment. When placed in culture, FACS-isolated, LEPR-expressing basal SCC progenitors exhibit higher colony-forming efficiency (n=3, P=0.0069) and form larger colonies (n=13 (LEPR), n=39 (LEPR+), P=0.0106) compared with non-expressing counterparts.

Relative to their normal skin counterparts, pan-tumour basal cells upregulated 886 transcripts by at least twofold (adjusted P0.05; Supplementary Table 2), whereas 562 transcripts were upregulated specifically during the transition from benign to malignant states (Supplementary Table 3).

Coupling our clonal skin HRASG12V mouse model with single-cell transcriptomics, chromatin landscaping, lentiviral reporters and lineage tracing, we show that aberrant crosstalk between cancer stem cells and their microenvironment triggers angiogenesis and TGF signalling, creating conditions that are conducive for hijacking leptin and leptin receptor signalling, which in turn launches downstream phosphoinositide 3-kinase (PI3K)AKTmTOR signalling during the benign-to-malignant transition.

Leptin normally circulates through the bloodstream, which we corroborated by enzyme-linked immunosorbent assays (ELISAs) of blood plasma from non-tumour bearing control mice. In tumours displaying a mixed phenotype, basal progenitors undergoing TGF signalling are enriched for CSCs with increased resistance to chemotherapy and immunotherapy, and the loss of TGF signalling reverts tumours to a benign state5,6,19.

Together, they allow scientists to align reads to a genome, assemble transcripts including novel splice variants, compute the abundance of these transcripts in each sample and compare experiments to identify differentially expressed genes and transcripts. We further documented this dependency by transducing FR-LSL-HrasG12V;Tgfbr2fl/fl;R26-LSL-YFP mice with a PGK-creERT2 lentivirus, and then administering tamoxifen to simultaneously ablate the TGF receptor, induce tumorigenesis and activate lineage tracing. & Gabrilovich, D.
