ABSTRACT
s Triple-negative breast cancer (TNBC), a heterogeneous tumor that lacks the expression of estrogen receptor (ER), proges-terone receptor (PR), and human epidermal growth factor receptor 2 (HER2), is more aggressive and tends to recur or metastasize. In contrast to other breast cancer subtypes, no approved endocrine or targeted treatments exist for TNBC. Therefore, identification of the prognosis characteristisics and potential therapeutic targets of TNBC could facilitate early personalized treatment. Owing to the rapid development of various technologies, researchers are increasingly focusing on the integration of "big data" and biological sys-tems, which is referred to "omics," as means of resolving it . Here, we review the recent progress in transcriptomics and proteomics re-search on TNBC.
