Roles of DDRs in tumor cell survival or proliferation. NSCLC, non-small-cell lung cancer; SCC, squamous cell carcinoma.

Receptor	Cell Survival or Cell Proliferation	Cancers
DDR1	increase	-Sarcoma [34] -Colon carcinoma [34] -Breast carcinoma [57,58] -Hodgkin’s lymphoma [52] -Prostate carcinoma [53] -Lung (NSCLC) [54], (adenocarcinoma) [49] -Gastric carcinoma [50] -Pancreatic carcinoma [55,56]
	decrease	-Breast carcinoma [59,60,71] -Colon carcinoma [61]
DDR2	increase	-Melanoma [62] -Oral SCC [63] -Gastric carcinoma [64,67] -Hepatocellular carcinoma [65] -Lymphoma [43] -Lung (NSCLC) [66]
	decrease	-Melanoma [68] -Fibrosarcoma [68,73]
