A Micropeptide XBP1SBM Encoded by lncRNA Promotes Angiogenesis and Metastasis of TNBC via XBP1s Pathway

Researchers identified a 21-amino-acid survival-associated micropeptide XBP1SBM, encoded by the long non-coding RNA (lncRNA) MLLT4-AS1, which was upregulated in TNBC tissues and glutamine-deprived TNBC cell lines.
