doi: 10.1158/0008-5472.CAN-24-3405
Figure Lengend Snippet: YAP transcriptionally regulates OXTR expression, which forms a positive feedback loop between Hippo/YAP and the OXTR. A, OXTR expression was significantly correlated with that of CCN1 ( CYR61 ) and CCN2 ( CTGF ) in HCC samples from the TCGA database. B, OXTR genome schematic and database analysis of the binding region of YAP or TEAD to the OXTR. Sites 1‒4 CRISPRi sgRNAs were designed to target the four OXTR sites. C and D, YAP ChIP‒qPCR and qRT-qPCR with or without CRISPRi in YAP-overexpressing SNU449 cells. E‒G, qRT-qPCR indicated that siRNA, VP, or VT104 treatment via the indicated method in SNU449 cells decreased the CTGF and CYR61 mRNA levels. H‒J, Immunoblot analysis showing the expression level of the OXTR in SNU449 cells treated with siYAP, VP, or VT104 via the indicated methods. Treatment inhibited OXTR protein expression and mRNA expression. K‒M, RT-qPCR showing the mRNA expression levels of the OXTR with siYAP, VP, or VT104 treatment via the indicated method in SNU449 cells. N and O, Immunofluorescence imaging of the OXTR (red) and DAPI (blue) in SNU449 cells subjected to the indicated treatments. Scale bar, 10 μm. All data are presented as the means ± SDs. ns, nonsignificant; **, P < 0.01; ***, P < 0.001 for comparisons (Student t test).
