In their Review, Ishani Sharma and Partha Roy examine the cell-intrinsic, niche-specific and #immune controls that govern #cancer dormancy transitions, and the strategies aimed at blocking relapse. journals.biologists.com/jcs/article/...
Figure showing regulation of dormancy emergence of DTCs in the lung microenvironment. On arrival in the lung, DTCs lodge in the alveolar and perivascular niches. Dormancy is enforced by several converging cues. These include contact with AT1 lung epithelium (which promotes survival and restrains growth), anti-proliferative action of vascular endothelium-derived TSP-1, sequestration of tumor-derived ECM remodeling enzymes (e.g. LOXL2) by endothelial PEAR1, and activation of a NAS1-driven NR2F1-based dormancy transcriptional program by stromal cell-derived BMP. NR2F1 mediates suppression of ΔNp63, the pro-proliferative isoform of p63 (TP63). Reactivation (indicated by the proliferation marker Ki67) occurs when tumor cells interact with AT2 epithelium (which provides pro-proliferative signals). Additional reactivation cues include tumor-derived factors tenascin-C and Coco (which antagonizes BMP to release the dormancy brake via integrin-dependent FAK signaling; phosphorylated FAK is indicated as pFAK), sprouting angiogenesis (which supplies TGF-β1 and periostin), and activation of integrin-dependent ERK–MLCK signaling triggered by alterations in the ECM (e.g. fibrotic ECM and/or remodeling of laminin by NET-derived proteases like MMP9). Together, these opposing endothelial, epithelial, stromal and matrix inputs determine whether DTCs remain dormant or undergo metastatic outgrowth in the lung.
