Potential driver for metastasis in bone cancer identified
Researchers discovered a new multidimensional MAPK7/MMP9 signaling hub in primary bone cancer metastasis, according to a study in Oncogene.
Using whole tumor plus single-cell RNA-sequencing and circulating tumor cells, researchers discovered mitogen-activated protein kinase 7/matrix metallopeptidase 9 (MAPK7/MMP9) signaling, acting as a driver for primary bone cancer metastasis, including lung metastasis.
Blocking this signaling pathway may suppress tumor burden and metastatic spread.
“The approach here finds that blockade of MAPK7/MMP9 signalling may overcome current hurdles for targeting pathways that ultimately lead to metastatic lung nodule formation in a childhood cancer,” the authors concluded.
