Cell Culture Protocols for Gastric Cancer

Check if the same lab product or an alternative is used in the 5 most similar protocols
The human GAC cell lines KATO-III and SNU-5 were purchased from the American Type Culture Collection (ATCC, Rockville, MD). Human GAC cell line MKN-45 was purchased from Creative Bioarray (Shirley, NY). Cell lines were authenticated by ATCC (KATO-III, SNU-5) or Creative Bioarray (MKN-45) and were routinely screened to ensure the absence of mycoplasma contamination (InvivoGen, San Diego, CA). The characteristics of these GAC cell lines are presented in Supplementary Table 1. Cells were cultured in RPMI 1640 medium (Sigma Chemical Co. St. Louis, MO) containing 10% or 20% FBS and maintained at 37°C in a humidified incubator with 5% CO2 and 95% air. Human gastric fibroblasts were purchased from ScienCell Research Laboratories (Carlsbad, CA) and cultured in a fibroblast specialty medium. Cytotoxic agents 5-FU, epirubicin (Epi), oxaliplatin (Oxa), docetaxel (Doc) and irinotecan (Iri) were purchased from the pharmacy at the Goshen Center for Cancer Care (Goshen, IN). Nintedanib was obtained from Boehringer Ingelheim Pharmaceuticals. The cell proliferation reagent WST-1 was purchased from Sigma-Aldrich.

Fibroblast experiments were carried out with serum‐free DMEM.
17 (link) Fibroblasts from randomly selected patients were immortalized by transducing hTERT expression.
15 (link) Unless otherwise indicated, all fibroblasts were seeded on 0.1% collagen (Sigma) coated tissue culture plates and stimulated with 2.5 ng/mL recombinant human TGF‐β1 (R&D Systems) for 3 days to regain their activated phenotype observed in patient samples,

23 (link) This TGF‐β1 concentration is comparable to the average concentration found in the bronchoalveolar lavage fluid of lung cancer patients.
24 (link) In some experiments, fibroblasts were treated with TGF‐β1 in the presence of 2 μM nintedanib (Boehringer Ingelheim, provided by Frank Hilberg). Lung carcinoma cell lines derived from ADC (H1437, H23) or SCC (H520, SK‐MES‐1) patients (ATCC) were used in growth and invasion assays. Cancer cells were cultured in a RPMI‐based medium.

Nintedanib Attenuates Bleomycin-Induced Lung Injury

Check if the same lab product or an alternative is used in the 5 most similar protocols
Nintedanib was administered once daily through gavage at 30, 60 and 100 mg/kg for 5 days before MV (Boehringer Ingelheim, Biberach, Germany) 21. The mice received a single dosage of 0.075 units of bleomycin in 100 μl of sterile normal saline solution intratracheally (Sigma‐Aldrich, St. Louis, MO, USA) and were ventilated 5 days after the administration of bleomycin 13.

The study was conducted in accordance with the Declaration of Helsinki, International Ethical Guidelines for Biomedical Research Involving Human Subjects (CIOMS), the Belmont Report, and the U.S. Common Rule. All patients provided a written informed consent approved by the Memorial Sloan Kettering Cancer Center Institutional Review Board. Nintedanib was provided by Boehringer Ingelheim GmbH. The senior academic authors had full access to all clinical and molecular data collected during the study and had final responsibility for the decision to submit the manuscript.

Nintedanib Modulates CCL4-Induced Liver Fibrosis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Nintedanib 30 and 60 mg/kg/day (provided by Boehringer Ingelheim Pharma GmbH & Co. KG) was administered once daily by oral gavage. Administration volume was 10 mL/kg body weight. In the preventive protocol (Figure 1), there were four treatment groups (n = 10 per group): control (corn oil); CCL4 and oral vehicle; CCL4 and Nintedanib 30 mg/kg/day; and CCL4 and Nintedanib 60 mg/kg/day. In the therapeutic protocol, there were six treatment groups (n = 10 per group): control (corn oil); CCL4 and oral vehicle; CCL4 and Nintedanib at 30 mg/kg/day starting at day 7; CCL4 and Nintedanib 60 mg/kg/day starting at day 7; CCL4 and Nintedanib at 30 mg/kg/day starting at day 14; and CCL4 and Nintedanib 60 mg/kg/day starting at day 14.

LDAC plus Nintedanib for AML Treatment

Check if the same lab product or an alternative is used in the 5 most similar protocols
LDAC was applied subcutaneously at 20 mg twice daily on days 1 to 10 in 28-day cycles. Nintedanib or placebo tablets identical in appearance (Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach an der Riss, Germany) were orally applied at 200 mg twice daily on days 1 to 28. Dose reductions to 150 mg or 100 mg Nintedanib/placebo twice daily were allowed. As a general rule, non-hematological grade 3 toxicities should be followed by permanent dose reduction off Nintedanib/placebo, unless effectively controlled with supportive therapy. Specific rules applied for gastrointestinal toxicities and liver enzyme elevations. Patients could continue treatment for up to 6 cycles of LDAC plus Nintedanib/placebo, disease progression or relapse, intolerance, or request of treatment discontinuation by patient or investigator. Patients without disease progression after 6 cycles could enter oral maintenance treatment with Nintedanib/placebo (up to 12 months from start of therapy).

Chemically-Induced Liver Fibrosis and HCC

Check if the same lab product or an alternative is used in the 5 most similar protocols
We generated a chemically-induced model of HCC and fibrosis in male C57BL/6J mice (Harlan Laboratories, n=58) by a single injection of N-nitrosodiethylamine (DEN) followed by weekly dosing with carbon tetrachloride (CCl4), as previously described25 (link). Once fibrosis was established, mice were randomized to receive vehicle or nintedanib (50 mg/kg, Boehringer Ingelheim). Mice were sacrificed at different time-points and liver and tumor tissue samples were collected and processed for histological, transcriptomic and protein expression analyses (see Supplementary material). All experimental procedures were carried out following the approval of the institutional ethical committee of the University of Barcelona and Hospital Clinic of Barcelona. Additionally, liver samples of a choline-deficient high-fat diet (CD-HFD) fed mouse model reported in a recent study26 (link) were collected. A total of 25 samples were processed for transcriptomic profiling, including mice fed a chow diet (n=5) or CD-HFD for 12 months and given: vehicle (n=4); aspirin/clopidogrel (Asp/Clo) (n=6) or sulindac (n=10).

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.
