F monoMSC, TE9, and TE15 with rhIGFBP2 to investigate the effect of IGFBP2 on malignancy in ESCC cell lines. The MTS assay demonstrated that rhIGFBP2 didn’t influence observed an increase in IGFBP2 levels in CAF15 compared with these in monoMSCs and the cell development and survival in the ESCC cell lines (Figure S5). Having said that, rhIGFBP2 signifia reduce in CAF15 siMT2A compared withand invasiveness of TE8, TE9, and TE15and S4). cantly promoted the migration those in CAF15 siNC (Figures 2C (Figure 4A,B). To We then confirmed that the three typessignaling pathways involved in these alterations, we performed Westidentify the intracellular of CAFlike cells expressed and secreted higher ern blotting IGFBP2 60 min after stimulating the 3 ESCC cell lines with rhIGFBP2. levels of IGFBP2 mRNA and10, 30, and protein than MSCs, utilizing qRTPCR, ELISA, and Western blotting revealed Moreover, the knockdown of MT2A Akt, Western blotting (Figures 2D and S8D).that rhIGFBP2 induced the phosphorylation ofin theErk, and NFB 100 min after CAFlike cells Palmitoylcarnitine MedChemExpress lowered the expressionits addition (Figures IGFBP2, usinginhibitors of PI3K (LY294002), and secretion of 4C and S9). The qRTPCR, ELISA, MEK1/2 (PD98059), and NFB (Bay1170982) suppressed rhIGFBP2induced migration and and Western blotting (Figures 2G andand TE15 cells (Figure 4D,E).
