CX3CL1 and cancer: Yang et al. (Cheng-Ning et al., 2015) found that microRNA-29b promotes OSCC migration by downregulating CX3CL1 expression, and that CX3CL1 expression levels are negatively correlated with lymph node metastasis and early tumor stage in OSCC patients, suggesting that CX3CL1 has anti-cancer effects in OSCC.
