Scale bar, 50 µ m. (B) U87 and C6 cells were treated with or without DRM (15 µ M) in the absence or presence of CQ (15 µ M) for 48 h, and the apoptotic cell ratio was measured by flow cytometry. (C) Graphical representation of quantitative analysis of the apoptotic rate. The results are presented as the mean ± SD of at least three independent experiments. ** P<0.01. CQ, chloroquine; CTR, control; DRM, doramectin.

Article Title: Inhibition of CDH11 Activates cGAS‐STING by Stimulating Branched Chain Amino Acid Catabolism and Mitigates Lung Metastasis of Adenoid Cystic Carcinoma

doi: 10.1002/advs.202408751

Figure Lengend Snippet: Combination of CXB/DMC/SD‐133 with CDH11 activates the cyclic GMP‐AMP synthase‐stimulator of the interferon gene (cGAS‐STING) pathway through ROS, suppressing cellular invasion and migration. A) Representative western blots of the cellular thermal shift assay showing increase in CDH11 thermostable performance in the presence of CXB, DMC, and SD‐133. B) SD‐133 with interactive residue side chains at the pocket are shown in stick rendering, with the inhibitors drawn in colorful. The polypeptide backbones are rendered as ribbons. The yellow broken lines indicate potential intermolecular hydrogen bonds, while the gray broken lines indicate pi‐cation interactions. C–E) Effect of CXB, DMC, and SD‐133 on the inhibition of SACC‐83 cells; normalized data and non‐linear regression curve fitting are shown. IC 50 values are indicated. F) BCAA per million SACC‐83 cells exhibited a decrease 24 h after treatment with CXB, DMC, or SD‐133. Mean ± SEM is shown, * P < 0.05 using t test. G) SACC‐83 cells treated with CXB, DMC, or SD‐133 analyzed for their migration and invasion ability using transwell assays. Scale bar, 100 µm, n = 3, Mean ± SEM is shown, * P < 0.05 using t test.

I) Expression of cGAS‐STING pathway‐related proteins in SACC‐83 cells, treated with CXB, DMC, and SD 133, assessed using western blotting. J) Flow cytometry reveals an increase in reactive oxygen species (ROS) production after treatment with CXB, DMC, or SD‐133. K,L) Confocal microscopy showing the accumulation and quantification of cytosolic deoxyribonucleic acid (DNA) in SACC‐83 cells following treatment with CXB, DMC, or SD‐133. Double‐stranded DNA (dsDNA) visualized using PicoGreen staining (green), while MitoTracker (red) and DAPI (blue) employed to label mitochondria and nuclei, respectively. Scale bar, 5 µm. More than 100 cells were analyzed per group. n = 10, Means ± SEM is shown. *** P < 0.001 using one‐way analysis of variance. M) Representative images of DNA comet assays of SACC‐83 cells subjected to treatment with CXB, DMC, or SD‐133.
