Abstract
- Simple Summary: In this study, we found that high FTSJ1 expression in triple-negative breast cancer patients was associated with poor prognosis and was associated with reduced infiltration of CD8+T cells in the tumor microenvironment. By knocking down FTSJ1, we observed an inhibitory effect on the proliferation and migration of triple-negative breast cancer, while inducing apoptosis and increasing the sensitivity of TNBC cells to T-cell-mediated cytotoxicity. This finding highlights the importance of FTSJ1 as a potential immunotherapy target in triple-negative breast cancer. FtsJ RNA 2′-O-methyltransferase 1 (FTSJ1) is a member of the methyltransferase superfamily and is involved in the processing and modification of ribosomal RNA. We herein demonstrate that FTSJ1 favors TNBC progression. The knockdown of FTSJ1 inhibits TNBC cell proliferation and development, induces apoptosis of cancer cells, and increases the sensitivity of TNBC cells to T-cell-mediated cytotoxicity. Furthermore, the high expression of FTSJ1 in TNBC attenuates CD8+T cell infiltration in the tumor microenvironment (TME) correlated with poorer prognosis for clinical TNBC patients. In this study, we establish that FTSJ1 acts as a tumor promotor, is involved in cancer immune evasion, and may serve as a potential immunotherapy target in TNBC. [ABSTRACT FROM AUTHOR]
