The wild-type CU428.2 and B2086.2 Tetrahymena strains were obtained from the Tetrahymena Stock Center (Cornell University, Ithaca, NY, USA). Wild-type and other motile strains were grown in the SPP (Super Proteose Peptone) medium50 (link) with the antibiotic–antimycotic mix at 1:100 (Sigma-Aldrich, St-Louis, MO, USA). Mutants with greatly reduced motility were grown in MEPP (Modified Enriched Proteose Peptone) medium, on which cells take up nutrients without using oral cilia51 (link), supplemented with the antibiotic–antimycotic mix at 1:30 (Sigma-Aldrich, St-Louis, MO, USA). Cells were grown with moderate shaking (80 rpm) at 30 °C. Cell swimming and cilia beating patterns were analyzed as previously described52 (link),53 (link). To induce protein overexpression, cells were cultured in media with 2.5 µg/ml CdCl2 for 16–18 h.

HEK293 FT wild-type and APEX1-KO cells were plated into 96-well plates at a density of 1.3 × 104 cells/well in DMEM with 10% fetal bovine serum (FBS) and antibiotic/antimycotic mix (Sigma, A5955-100, St. Louis, MI, USA). CH12F3 wild-type and APEX1-KO cells were collected by centrifugation and resuspended in phenol red-free RPMI-1640 with L-glutamine, 10% FBS, and antibiotic/antimycotic mix (Sigma, A5955-100, St. Louis, MI, USA) and then plated on 96-well plates at a density of 2.2 × 104 cells/well. The plates were incubated for 24 h at 37 °C in a 5% CO2 humidified incubator. Immediately prior to use, the Ape1 inhibitors and methylmethane sulfonate (MMS) were diluted with a culture medium containing 3% FBS. For both HEK293 FT and CH12F3 cells, the FBS in the medium was reduced from 10% to 3% before the addition of inhibitors or MMS. After 24 h of treatment, MTT (3-(4,5-dethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) was then added at a concentration of 0.5 mg/mL, followed by a 3-h incubation. Stop solution (1% SDS and 0.01 M HCl) was used to dissolve formazan crystals, and the absorbance was measured at 590 nm.

We used PDAC cell lines (derived from primary tumors) Panc02.03 (ATCC® CRL-2553), Panc08.13 (ATCC® CRL-2551), Panc10.05 (ATCC® CRL-2547) and Panc-1 (ATCC® CRL-1469). Panc02.03, Panc08.13 and Panc10.05 were cultured in RPMI-1640 (Gibco) supplemented with 15% FBS (Gibco), cyprofloxacine, antibiotic/antimycotic mix, glutamine (Sigma) and 10 U/ml human recombinant insulin (Santa-Cruz). Panc-1 cells were cultured in DMEM with 10% FBS (Gibco) and antibiotics. The control immortalized Human Pancreatic Duct Epithelial Cell Line (H6c7, HPDEC, Kerafast) was maintained in keratinocyte serum-free medium that contained EGF and bovine pituitary extract (Thermo Fisher, 17005042), antibiotic/antimycotic mix and glutamine (Sigma). Cells were tested for mycoplasma contamination with Hoechst staining and only negative cultures < 9 passage numbers were used in our experiments. Cells were washed three times with phosphate buffered saline (PBS) 2 days after culturing them in serum-free medium, the medium was then replaced and EVs were collected after 2 days. For 3D cultures, cells were removed from culture dishes (Eppendorf) with TrypLE (Gibco), embedded into Matrigel with 20,000 cells/droplet (25 μl) and cultured in 2.5% EV-free FBS (exosome depleted One-Shot FBS, Gibco) prior change to serum-free medium 2 days before starting EV collection.

Leptin and Sirtinol were purchased from Sigma Aldrich (Saint Louis, MO). All cell culture reagents, with the exception of fetal bovine serum (Atlanta Biologicals, Lawrenceville, GA) and antibiotic/antimycotic mix (Sigma Aldrich, Saint Louis, MO) were purchased from Invitrogen (Carlsbad, CA).

HCT116, SW620, and HT29 CRC cell lines were a kind gift from Prof. Kari Alitalo, University of Helsinki, Finland. SW1222 cells and normal human colon fibroblasts (ATCC-1459) were from ECACC and ATCC, respectively. Thp-1 cells were from ATCC. Cells were cultured in DMEM high glucose (Gibco) supplemented with 10% FCS (Gibco), cyprofloxacine, antibiotic/antimycotic mix, and glutamine (Sigma). Cells were tested for mycoplasma contamination with Hoechst staining and only negative cultures were used in our experiments. Two days before EV collection, cells were washed with PBS three times and they were further cultured in either medium without FBS or containing 2.5% EV-free FBS. EV-free FBS was prepared by overnight ultracentrifugation at 100,000g or purchased from Gibco (exosome depleted One-Shot FBS). For 3D cultures, cells were treated with TrypLE (Gibco), embedded into Matrigel with 5000–10,000 cells depending on the cell line and cultured for 12-14 days.

Porcine Vascular Tissue Culture

Abattoir pig vessels largely from white X female pigs aged 8–10 weeks old were obtained from the Royal Veterinary College. Fresh tissue was collected and used within 4 h. The 50–500 mg segments of vessel or perivascular aortic adventitia were cultured in serum-free DMEM supplemented with antibiotic/antimycotic mix (Sigma-Aldrich, St. Louis, MO., USA) at 37 °C, 5% CO2 and 95% air, as previously described for rat and human vessels [56 (link),57 (link)]. Serum-free media was used, as most sera contain large amounts of oxylipins (unpublished observations). Organ culture was performed for just the first 24 h after explant in order to minimize cell differentiation. In some experiments, lipopolysaccharide (LPS; E. coli, 1 μg/mL) was given to induce an inflammatory response.

The cells were cultivated in DMEM (Sigma Aldrich) supplemented with 10% fetal bovine serum (Sigma Aldrich) and 1% antibiotic–antimycotic mix (Sigma Aldrich) in a 37°C incubator (Sanyo; CO2: 5%, relative humidity: >95%). A medium containing 1% antibiotic–antimycotic mix and 0% or 2% fetal bovine serum was used for infection and propagation, respectively. Human Coxsackievirus A10 was obtained from the ATCC and grown on RD cells. The stocks were frozen at −80°C and virus titers were determined by TCID50 assay.

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.
