Genetic or pharmacological inhibition of ERRγ in SCLC cells effectively decreased collagen deposition in the ECM as assessed using the collagen probe CNA35-mCherry, qRT-PCR and western blotting for COL6A1 (Figs. 5A,B,G and  4E,F; Appendix Fig. S4A,B). This evidence concerns the gene ESRRG and small cell lung carcinoma.
