doi: 10.1002/mco2.70148

Figure Lengend Snippet: The expression levels of TGFβ2 in gastric cancer tissues and normal tissues were analyzed using data from the TCGA and GTEx databases (A). The relationship between TGFβ2 expression levels and overall survival time was analyzed (B). Representative images of IHC staining in gastric cancer tissues and adjacent noncancerous tissues, using an antibody against TGFβ2, are shown (C). In 212 paired samples, TGFβ2 expression was significantly different between gastric cancer tissues and adjacent noncancerous tissues (D). The effects of stable TGFβ2 interference and overexpression in gastric cancer cell lines were confirmed by Western blot analysis (E). Analysis of gastric cancer samples revealed a significant association between upregulated TGFβ2 expression and 5‐year overall survival in patients with gastric cancer (F). TGFβ2 interference and overexpression were validated at the RNA level (G) (scale bars: 500 and 50 µm). Statistical significance is indicated as follows: ** p < 0.01, *** p < 0.001.

Figure Lengend Snippet: Chronic exposure to TGFβ2 induces upregulation of functional TRPV4 channels alongside the autoinhibitory canonical modulator SMAD7. TRPV4-mediated Ca 2+ influx, canonical, and non-canonical TGFβ2 signaling stimulate Rho/ROCK signaling, augment cytoskeletal contractility, and stimulate ECM release to increase the flow resistance of the conventional pathway. Increased contractility drives OHT, resulting in a feedforward vicious TRPV4-dependent circle loop that maintains ocular hypertension. Schematic made using Biorender.com.
