To determine whether and which exosome-secreted WNT proteins are regulated by GOLPH3, we screened the literature and found that among the 19 WNT subfamily members, WNT1, WNT2, WNT3, WNT3A, WNT5A, WNT7B, and WNT11 were reported to be expressed in NSCLC [22, 23]. Here, WNT2 is linked to non-small cell lung carcinoma.
