Article Title: Overexpression of JMJD6 drives immune evasion via the BRD4–IRF1–PD-L1 axis and promotes malignancy in gastric cancer

doi: 10.1038/s41598-025-30705-y

Figure Lengend Snippet: Graphical abstract. Graphical abstract illustrating the hypothetical mechanism by which JMJD6 promotes tumor progression and immune evasion in GC. JMJD6 is overexpressed in gastric cancer cells and promotes BRD4 expression, which upregulates IRF1 and consequently increases PD-L1 expression. Elevated PD-L1 expression on tumor cells inhibits T cell–mediated antitumor immunity, thereby facilitating immune escape.

Article Snippet: Anti-JMJD6 mouse monoclonal antibody (sc-28348; Santa Cruz Biotechnology, TX, USA), anti-PD-L1 rabbit monoclonal antibody (13684; Cell Signaling Technology, MA, USA), anti-ACTB rabbit monoclonal antibody (3700; Cell Signaling Technology), anti-BRD4 rabbit polyclonal antibody (A301-985A50; Bethyl Laboratories, TX, USA), and anti-IRF1 rabbit monoclonal antibody (8478; Cell Signaling Technology) were used.

Figure Lengend Snippet: JMJD6 regulates BRD4, IRF1 and PD-L1 expression. ( a ) The knockdown of JMJD6 by transfection with siRNA-JMJD6 suppressed BRD4, IRF1 and PD-L1 in MKN74. In addition, the knockdown of BRD4 by transfection with siRNA-BRD4 suppressed IRF1 and PD-L1 in MKN74. In contrast, the knockdown of BRD4 did not suppress JMJD6 in MKN74. ( b ) Knockdown of JMJD6 suppressed PD-L1 and BRD4 expression in MKN74 gastric cancer (GC) cells. White dotted lines indicate nuclear boundaries. ( c ) Co-culture assay of GC cells and T cells. Under JMJD6 knockdown, T cells had more potent anti-tumor activity against GC cells compared with NC, and the proliferation ratio of GC cells was significantly decreased (mean ± SD, n = 3; error bars indicate SD, n = 3). ( d ) An impedance-based tumor-cell killing assay. The knockdown of JMJD6 increased the anti-tumor activity of T cells and inhibited the proliferation of GC cells. ( e ) JMJD6 overexpression using plasmid transfection promotes BRD4, IRF1 and PD-L1 expression. ( f ) A hypothetical model of the overexpression or activation of JMJD6 in GC cells.

Article Title: USP35 promotes the growth of ER positive breast cancer by inhibiting ferroptosis via BRD4-SLC7A11 axis.

doi: 10.1038/s42003-025-07513-1

Figure Lengend Snippet: Fig. 8 | A working model of USP35 regulating ferroptosis in ER+ breast cancer tumors. USP35 interacts with and deubiquitinates BRD4, stabilizing the protein level of BRD4 that regulates SLC7A11. This interaction leads to USP35-invoked upregu- lating SLC7A11 expression, inhibiting ferroptosis, and promoting cell growth in ER+ breast cancer.
