Further signalling pathways influencing COL1A1 transcription via (at least to some extent) TGFβ are Mer Tyrosine Kinase (MERTK) [61], PKCε [62], Ovarian cancer G-protein coupled Receptor-1 (OGR1) [63], β-catenin [56], and osteopontin (more details can be found in Appendix A, Table A5). The gene discussed is TGFB1; the disease is ovarian cancer.
