The human cell lines used in this study include HCT116, DLD-1, AsPC-1, PL5 and HEK293T (American Type Culture Collection, Manassas, VA, USA) and HuP-T3 (Sigma-Aldrich, St Louis, MO, USA). Cell culture was carried out in McCoy's 5A modified medium (Sigma-Aldrich; for HCT116), RPMI-1640 medium (Wako, Osaka, Japan; for DLD-1, AsPC-1 and PL5) and Dulbecco's modified Eagle's medium (Wako; for HuP-T3 and HEK293T). Media were supplemented with 5% fetal bovine serum (BioWest, Nuaillé, France) and 1% penicillin/streptomycin (Wako) prior to use for regular cell culture. The transfection of cells with the plasmids was performed using TransIT-LT1 transfection reagent (Mirus Bio, Madison, WI, USA) according to the manufacturer's instructions. Selection of cells with G418 (Life Technologies) was carried out at concentrations of 0.4 mg/ml (PL5 and HuP-T3), 0.8 mg/ml (HCT116 and AsPC-1) or 1 mg/mL (DLD-1) throughout the study.

Establishment of Patient-Derived PDAC Models

Check if the same lab product or an alternative is used in the 5 most similar protocols
Patient-derived samples were obtained from consented patients under an Institutional Review Board (IRB)-approved protocol LAB07-0854 chaired by J.B.F. (UTMDACC). Patient-derived models PATC53, PATC124, PATC148 and PATC153 were generated as previously described5 (link) and kindly provided by Dr Jason Fleming and Dr Michael Kim (MDACC). The cells were routinely maintained in DMEM/F12 Medium (Corning #10-090-CV) supplemented with 10% fetal bovine serum (Sigma #F2442) in a humidified incubator (37 °C, 5% CO2). LSL-KrasG12Dp53L/+ mouse PDAC cell lines were kindly provided by Dr Haoqiang Ying and cultured in RPMI 1640 (Gibco #72400-047) supplemented with 10% fetal bovine serum. PK-59 cell line was obtained from Riken Cell Bank and maintained in RPMI 1640 (Gibco #72400-047) supplemented with 10% fetal bovine serum. KP-3 and KP-4 cell lines were obtained from JCRB Cell Bank. Hup-T3 and Hup-T4 were obtained from Sigma. All other PDAC generic cell lines were obtained from ATCC and maintained following ATCC’s recommendations. Cell lines were validated by STR profiling and confirmed to be negative for mycoplasma.

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.
