Renal tumour-initiating cells (T-ICs) contribute to tumorigenesis, progression and drug resistance of renal cell carcinoma (RCC). However, the underlying mechanism for the propagation of renal T-ICs remains unclear. Here we show that long non-coding RNA lncARSR is upregulated in primary renal T-ICs and associated with a poor prognosis of clear cell RCCs (ccRCC). Knockdown of lncARSR attenuates the self-renewal, tumorigenicity and metastasis of renal T-ICs. Conversely, forced lncARSR expression enhances T-IC properties of RCC cells. Mechanistically, the binding of lncARSR to YAP impedes LATS1-induced YAP phosphorylation and facilitates YAP nuclear translocation. Reciprocally, YAP/TEAD promotes lncARSR transcription, thus forming a feed-forward circuit. The correlation between lncARSR and YAP is validated in a ccRCC cohort, where the combination of these two parameters exhibits improved prognostic accuracy. Our findings indicate that lncARSR plays a critical role in renal T-ICs propagation and may serve as a prognostic biomarker and potential therapeutic target. Renal tumour-initiating cells (T-ICs) contribute to tumour initiation and progression. Here, the authors show that lncARSR regulates TICs by blocking LATS1-induced YAP phosphorylation facilitating YAP nuclear translocation, which promotes lncARSR transcription, thus forming a feed-forward circuit to promote TIC expansion.
