Cell lysates were separated by 10% SDS-PAGE. The specific primary antibodies used in Western blotting analysis are as follows: FAP (1:1000,
ab53066, Abcam, UK), α-SMA (1:1000,
ab5694, Abcam), IL11 (1:1000,
ab89887, Abcam), IL15 (1:800,
ab7213, Abcam);
VEGFA (1:1000,
wl00009b, Wanleibio, China); p-VEGFR2 (1:800, D155165, Sangon, China), T-VEGFR2 (1:1000, D151118, Sangon), p-KIT (1:800, D151515, Sangon), p-PDGFRβ (1:800, D151409, Sangon); FXR1 (1:1000, BS70701, bioworld, China); YAP1 (1:1000,
sc-398182, Santa Cruz, USA); T-STAT3 (1:1000, #4904, CST, USA), p-STAT3 (1:1000, #9131, CST), T-AKT (1:1000, #9272, CST), p-AKT (1:1000, #2965, CST), T-ERK (1:1000, #9102, CST), p-ERK (1:1000, #4348, CST), T-P38 (1:1000, #9212, CST), p-P38 (1:1000, #4631, CST) and
β-Actin (1:1500, ZSBIO, China). For ELISA assay, conditioned medium was collected from 1 × 10
6 NFs or CAFs in a 6-well plate, and the concentrations of IL11 and IL15 were measured using a standard ELISA Kit (Raybiotech, USA) according to the manufacturer's instructions.
