Figure Lengend Snippet: TNF-α modulates the WISP1 expression in stroma cells of the human bladder. (A) The RT-qPCR determined the expression of WISP1 in the human bladder cells. (B) Two WISP1 isoforms (WISP1v1 and WISP1v2) were found in the human bladder fibroblast (HBdSF) and bladder smooth muscle (HBdSMC) cells by RT-PCR with the pair of primers as shown. The expressions of WISP1, IL-6, CXCL5, CXCL12, and GDF15 of the HBdSF (C) and HBdSMC (D) cells after 10 ng/ml TNF-α treatment assessed by RT-qPCR. WISP1 (E) and IL-6 (F) secretions after TNF-α (0 – 20 ng/mL) treatments in HBdSF cells. Secretion of WISP1 (G) and IL-6 (F) in HBdSMC_shCOL and HBdSMC_shWISP1 cells treated with/without 10 ng/ml of TNF-α. Data are presented as the mean percentage (± SE; n = 4) in relation to the vehicle-treated HBdSMC_shCOL cells. (I) WISP1 secretion after 20 μM CAPE and/or TNF-α in HBdSF cells determined by ELISA assays. Data are presented as the mean percentage (±SE; n = 4) in relation to the vehicle-treated HBdSF cells. (J) The luciferase activity of the WISP1 reporter vector when HBdSMC cells were treated with TNF-α (10 ng/mL) and/or 20 μM CAPE for 24 h. * p < 0.05; ** p < 0.01; ND: no detectable.

Figure Lengend Snippet: WISP1 modulates expressions of α-SMA, IL-6, GDF15, and CXCL5 in bladder stroma cells. The mRNA levels of two WISP1 isoforms (WISP1v1 and WISP1v2) after WISP1 knock-downed in the HBdSF (A) and HBdSMC (B) cells were determined by RT-PCR. The protein levels with quantification analysis of WISP1, GDF15, and α-SMA of HBdSMC (C) and HBdSF (D) cells after mock-knockdown or WISP1-knockdown were assessed by immunoblot assays. The mRNA levels of the WISP1, α-SMA, IL-6, GDF15, and CXCL5 after knockdown of WISP1 in the HBdSMC (E) and HBdSF (F) cells, as indicated, were determined by RT-qPCR. Data are presented as target genes/β-actin of mock-knockdown cells relative to WISP1-knockdown cells. ** p < 0.01.

Figure Lengend Snippet: A Treatment timeline for a representative CRLM patient. The patient underwent Dixon surgery following CRLM diagnosis. First tumor evaluation showed a new metastasis in liver S5, and subsequently, RFA was performed. Postoperative PET/CT showed no tumor viability. Intrahepatic S7 metastasis appeared 4 months later. S5 and S7 tissues were obtained through hepatic resection, and pathological examination as well as sequencing were performed. The second progression with new lung metastases occurred at 7 months. Triangles: liver or lung metastases. B Neutrophil infiltration levels in tumors pre- and post-iRFA analyzed by different datasets (Box center line: median; box limits: upper and lower quartiles; whiskers: 1.5× interquartile range).
