CCL18 and breast carcinoma: Ling et al. (2011) reported that pachymic acid inhibits breast cancer cell invasion by suppressing nuclear factor-κB-dependent matrix metalloproteinase-9 expression [11]; Hong et al. (2012) demonstrated that pachymic acid reduces breast cancer cell metastasis via suppression of the phosphorylation of PITPNM3 and the interaction of CCL18 with PITPNM3 [12].
