Figure Lengend Snippet: Elevated ABHD16A triggered by ACh was associated with poor prognosis in patients with gastric cancer. A, Representative IHC images of ABHD16A expression in human normal gastric tissues and gastric cancer tissues from the TMA with magnifications of 40×, 100×, and 200×. Scale bar for 200×, 100 μm. B–D, Relationship of ABHD16A IHC score to clinical stage ( B ), pT stage ( C ), and lymph node metastasis ( n = 80; D ). E, Cumulative survival curves of patients with gastric cancer with high or low ABHD16A expression based on the TMA. F, IHC images and score of ABHD16A in S100 + or S100 − gastric cancer tissues. Scale bar, 100 μm. G, Procedure for coculture of DRG neurons and gastric cancer cells. H, Western blotting was used to analyze ABHD16A levels in MFC cells cocultured with DRG neurons or DRG neuron–derived CM. GAPDH served as the loading control. I, Expression of HIF1A and ABHD16A in neurotransmitter [HA, dopamine (DA), 5-HT, norepinephrine (NE), ACh]-treated MFC cells and ACh-treated MGC-803 cells. J, ACh concentration was detected in DRG CM by ELISA. K, Tumor volume of orthotopic gastric cancer tumors with or without vagotomy. L, Representative mIF staining images of FOXP3, CD163, CD11b, CD8, PD-L1, and Pan-CK in gastric cancer tissues with high or low expression of ABHD16A. Scale bar, 100 μm. **, P < 0.01; ***, P < 0.001; ****, P < 0.0001.
Article Snippet: ACh in the dorsal root ganglion (DRG)–derived conditioned medium (CM) was detected using the ACh ELISA kit (Elabscience, E-EL-0081).
