Our studies showed that LNK was abnormally expressed in TNBC, thus we can speculate that the LNK may have a certain correlation with TNBC, which indicated that LNK protein may have a certain relationship with the function of TNBC, If indeed LNK functions as a tumor suppressor or promotor in TNBC, possibly it can be a therapeutic target, which can promote us to make progress in TNBC. The gene discussed is SH2B3; the disease is neoplasm.
