The mRNA and protein expression of the LYNX1 has been found in lung, colon, epidermis, and breast cancer cells [14], and in lung adenocarcinoma A549 and colon carcinoma HT-29 cell lines, the colocalization of LYNX1 with α7-nAChRs has been reported in cell membranes [14]. Here, LYNX1 is linked to breast cancer.
