Equal amounts of proteins extracted from the different groups were run on 10% SDS-PAGE and transferred to PVDF membranes (Amersham, St. Albans, UK). Membranes were incubated with mouse anti-vimentin monoclonal antibody (Santa Cruz; 1:500) and mouse anti-CK-19 monoclonal antibody (Santa Cruz; 1:500) respectively overnight at 4 °C. The membranes were then incubated with HRP-conjugated goat anti-mouse IgG (ZSJQ-Bio; 1:2000) at room temperature for 1 h. ECL detection reagents (Millipore) were added to the membranes and they were immediately exposed to x-ray film (Kodak, Rochester, NY, USA).The β-actin signal was used as a control to ensure equal protein loading.

Paraffin-embedded tumor tissues were cut in 4-μm sections, deparaffinized in xylene, and rehydrated through a graded ethanol series. Next, the sections were rinsed three times in 1X PBST (PBS with Tween 20). The sections were then blocked in 1X PBS containing 0.5% Triton X-100 and 5% sheep serum for 30 min at room temperature before incubating them overnight at 4 °C with a rabbit anti-Prx II polyclonal antibody (AbFrontier technology, Seoul, South Korea) and a mouse anti-vimentin monoclonal antibody (Santa Cruz Biotechnology). Sections were again rinsed three times in 1X PBST. To detect the bound primary antibodies, the sections were incubated in the dark at room temperature for 90 min with goat anti-rabbit and goat anti-mouse antibodies (Santa Cruz Biotechnology). Slides were counterstained for 20 min in the dark with DAPI diluted in 1X PBS before visualization and image capturing under a microscope.

The samples were electrophoresed in 4–12% Bis-Tris gels at 100 V using MES running buffer. The proteins were electrophoretically transferred to a nitrocellulose membrane at 100 V for 1.5 h. The membrane was blocked with 3% milk in PBS 1X at 37°C for 2 h. The blots were incubated with primary antibodies: rabbit anti human LASP-1 polyclonal antibody, 1:500 in 0.3% BSA-PBS (Millipore); rabbit anti-green fluorescent protein polyclonal antibody, 1:100 in 0.3% BSA-PBS (Santa Cruz Biotechnology); mouse anti-vimentin monoclonal antibody, 1:1000 in 0.3% BSA-PBS (Santa Cruz Biotechnology) at room temperature overnight, washed three times with PBS, then incubated with an alkaline-phosphatase-conjugated secondary antibody (1:7500 in 0.3% BSA-PBS) for 4 h at 37°C.

The BM tissue samples were used for immunohistochemistry and Gomori’s stain. The rabbit anti-FSP1/S100A4 monoclonal antibody (Millipore, Billerica, MA, USA), rabbit anti-FAP polyclonal antibody (Abnova, Taipei, Taiwan), goat anti-α-SMA polyclonal antibody (Abcam, Cambridge, MA, USA), rabbit anti-GDF15 monoclonal antibody (Cell Signaling, Danvers, MA, USA), mouse anti-Vimentin monoclonal antibody (Santa Cruz, Dallas, CA, USA), and mouse anti-CD68 monoclonal antibody (Abcam) incubations were performed according to the manufacturer’s instructions. Images of the slides stained for these markers were scanned at 40× magnification using the optical microscope (Olympus Co., Tokyo, Japan). The positive rate of each marker was quantified by counting the ratio of the positive cells in all nuclear cells. The reticulin fiber density (RFD) of the samples was assessed according to Norén-Nyström et al [18 (link)]. All readings and estimations were performed in a blinded manner.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
