Finally, a trio of lncRNAs have been found to regulate trastuzumab resistance in Human Epidermal Growth Factor Receptor positive (HER2+) breast cancer cells, including Actin Filament Associated Protein 1 Antisense RNA1 (AFAP1-AS1), AGAP2-AS1, and small nucleolar RNA host gene 14 (SNHG14). Here, SNHG14 is linked to breast cancer.
