Emerging evidence suggests that miRNAs (miR) can modulate a complex gene network in a cell-intrinsic and non-cell autonomous manner. We previously identified by transcriptomic analysis miR-192 to be heavily downregulated in different highly metastatic subpopulations (HMS) isolated from bone metastases in a lung cancer mice model, but its mechanistic contribution to the prometastatic activity remains unknown.To delineate the pleiotropic functions elicited...

C5aR is a membrane-associated receptor for C5a, a potent immune mediator generated after complement activation. C5aR expressed in tumor infiltrating immune cells creates a favorable microenvironment for tumor progression. However, the expression of C5aR by cancer cells and its contribution to their malignant phenotype is poorly understood. Immunohistochemical analysis revealed that high levels of C5aR in human lung tumors were associated with poor survival (P=0.005) a...
