CRC cells (4 × 105) were treated with Obatoclax (0, 100, 200 μM) for 24 h, or treated with Obatoclax for 22 h and then combined with MG132 (20 μM) for an additional 2 h. After drug treatment, cells were lysed, subjected to SDS-PAGE, blot transfer, incubation with primary and secondary antibodies, exposure to enhanced chemiluminescence (ECL) reagent, and final visualization of the antigen-of-interest using the LAS3000 system (Fujifilm; Tokyo, JPN) as stated previously [45 (link),46 (link)]. Densitometry analysis of immunoblot signals was accomplished by ImageJ software (National Institute of Health, Bethesda, MD, USA). Anti-survivin (#ab469) and anti-TCF4 (#ab76151) antibodies were bought from Abcam (Cambridge, GBR). Anti-β-catenin (sc-7963) and anti-c-MYC (sc-40) were purchased from Santa Cruz Biotechnology (Dallas, TX, USA). Anti-LEF1 (GTX129186) and anti-GAPDH (GTX627408) were obtained from GeneTex (Hsinchu, TWN), and anti-β-tubulin (#T2200) was bought from Sigma-Aldrich (St. Louis, MO, USA). Primary antibodies against cyclin D1 (#2926), HA-tag (#3724), and cleaved forms of caspases-3 (#9664), -8 (#9496), -9 (#9501), and PARP (#9541) were all purchased from Cell signaling Technology (Boston, MA, USA).

TGFβ1 was purchased from Peprotech (Rocky Hill, NJ). The primary antibodies were used at 1:1000 ratio. Monoclonal anti-CD63 (H5C6, The Developmental Studies Hybridoma Bank, Iowa City, IA), anti-CD81 (MAB 4615, R&D Systems, Minneapolis, MN), anti-Thy-1.2 (HO-13-4, ATCC and 550402, BD Biosciences, San Diego, CA), anti-GAPDH (GTX627408, GeneTex, Irvine, CA) and rabbit polyclonal anti-calnexin (2679S, Cell Signaling, Danvers, MA) were used to detect EV and cellular proteins. Monoclonal anti-FN-EDA (ab6328, Abcam, Cambridge, MA), monoclonal anti-collagen I (GTX26308, GeneTex) and rabbit polyclonal anti-α-SMA (CBL171-I, EMD Millipore, Temecula, CA) anti-collagen III (GTX111643, GeneTex) and anti-N-cadherin (GTX127345, GeneTex) were used in western blotting studies.

Quantification of Viral Titers and Proteins

Lung tissues were homogenized in DMEM using the bead-beating technology (Precellys Lysing kits; Bertin Technologies, Aix-en-Provence, France). Following centrifugation, supernatants were stored in small aliquots. Viral titers were determined using a plaque assay following a previously described methodology [12 (link)]. For western analysis, thawed supernatants were mixed with equal amounts of RIPA buffer containing lysozyme and proteinase inhibitors. The protein content was measured with a protein assay kit (Bio-Rad, Richmond, CA, USA). Equal amounts of cellular proteins were separated by SDS-PAGE and subsequently transferred onto polyvinylidene fluoride membranes. Subsequently, the membranes were immunoblotted with specific primary antibodies and subsequently exposed to horseradish peroxidase (HRP)-conjugated secondary antibodies. The Immobilon Western HRP Chemiluminescence Substrate (Millipore, Burlington, MA, USA) was used for blot development. Mouse monoclonal anti-nucleocapsid (GTX632269, 1:2000 dilution) and anti-GAPDH (GTX627408, 1:5000 dilution) antibodies were obtained from Genetex (Hsinchu, Taiwan).

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.
