Culturing Human Pancreatic Cancer Cell Lines

The human pancreatic cancer cell lines BxPC-3 (cat# CRL-1687), AsPC-1 (CRL-1682), CFPAC-1 (CRL-1918), and PANC-1 (CRL-1469) were obtained from the American Type Culture Collection (ATCC) (Manassas, VA, USA). Both BxPC-3 and AsPC-1 cells were cultured in RPMI 1640 medium (SH30255.01; HyClone, Logan, UT, USA) with 1.0% sodium pyruvate and 10% FBS (100–106; Gemini Bio Products, Sacramento, CA, USA). The CFPAC-1 cells were cultured in IMDM (30–20065; ATCC) with 10% FBS. Each cell line's identity was confirmed by the Genetic Resources Core Facility of Johns Hopkins University (Baltimore, MD, USA). Additionally, HEK293 cell lines that stably express the human DUOX2 gene alone or with human DUOXA2 were kindly provided by Dr. William M. Nauseef (University of Iowa, Iowa City, IA, USA) and were maintained as described [63 (link)]. To establish starvation conditions before each experiment, cells were cultured overnight in the same medium without FBS. Starvation conditions were used because DUOX2 induction by IFN-γ is stronger after serum starvation, as noted previously [11 (link), 12 (link)]. In all cases, cells were cultured in a humidified incubator at 37°C in an atmosphere of 5% CO2 in air. We previously found that the basal levels of all Nox homologues (Nox1-5 and DUOX1-2) were negligible in BxPC-3, AsPC-1, and CFPAC-1 cells, as determined by real-time RT-PCR [11 (link)].

Establishment and Characterization of PDAC Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
PDAC cell lines were cultured in a 1:1 mix of DMEM and Ham’s F-12 media (Mediatech) supplemented with 10% fetal bovine serum (Life Technologies), penicillin (100 U/ml), and streptomycin (100 μg/ml) at 37°C in 5% CO2. Numerically named PDAC cell lines were all established between 2008 and 20012 in our laboratory from xenograft tumors derived from surgically resected PDAC. These cell lines are described in more detail in the supplemental experimental procedures. BxPc3 (2010), COLO357 (2011), CFPAC-1 (2002), and PANC-1 (2002) were obtained from ATCC. Mouse PDAC cell line NB494 (2015) was a generous gift from Nabeel Bardeesy (Massachusetts General Hospital) (8 (link)). All cell lines were routinely evaluated for morphology and tested for mycoplasma. No genetic authentication was performed. Experiments evaluating the effects of BET inhibition employed CPI203 (BETi), and its inactive enantiomer CPI440 or DMSO as controls.

Silencing UBE2S in Pancreatic Cancer Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Pancreatic cancer cell lines PANC-1 and CFPAC-1 were both obtained from ATCC. PANC-1 cells were cultured in DMEM (Gibco, USA) which was supplemented with 10% fetal bovine serum (FBS). CFPAC-1 cells were cultured in RPMI 1640 (Gibco, USA) which was supplemented with 10% FBS. The cells were grown in 5% CO2-saturated humidity at 37°C and sub-cultured by digesting with trypsin-EDTA.
Pancreatic cell lines PANC-1 and CFPAC-1 were plated in 6-well plates at an appropriate density (40–60% cell density at time of transfection) before transfection with 3 μL UBE2S-RNAi (40 pmol) in a certain amount of serum-free medium, along with the presence of 2 μL lipofectamine 2000, according to the manufacturers’ instructions. The cells were incubated with transfection mixture about 4–6 hrs and that was replaced with fresh medium after transfection. siRNAs for UBE2S and one negative control siRNA were synthesized by Genepharm Technologies (Shanghai, China). The effects of gene silencing were confirmed by Western blotting 48 hrs after transfection.

Check if the same lab product or an alternative is used in the 5 most similar protocols
The human pancreatic adenocarcinoma cell line CFPAC-1 and AsPC-1 were obtained from ATCC and were cultured in RPMI or DMEM media supplemented with 10% fetal bovine serum. These PDAC cell lines were single-cloned and screened by Western blotting for CD44 expression. To develop gemcitabine-resistant cells, CD44 low single clone cells were transiently exposed to gemcitabine for 16 h once a week with increasing concentrations (50 ng/ml to 1.0 µg/ml) of gemcitabine weekly for more than 2 months. The resulting gemcitabine-resistant cells were referred to as GR and the original gemcitabine-sensitive cells were referred to as GS.

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.
