Pancreatic Cancer Cell Line Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols
AsPC1, PANC1, BxPC3, H460, A549, and PC3 cells were purchased from the American Type Culture Collection (Manassas, VA). PANC1, BxPC3, H460, and PC3 were cultured in Roswell Park Memorial Institute (RPMI)-1640 medium and AsPC1 in Dulbecco’s Modified Eagle Medium (DMEM), both supplemented with 10% fetal bovine serum, 100 units/ml penicillin and 100μg/ml streptomycin (Invitrogen). All cells were initially plated in their corresponding complete media for metabolic and cell death analyses. Cells were incubated at 37°C in a humidified incubator with 5% CO2. We avoid exposing carcinoma cell lines to heat-inactivated serum to maintain stable metabolic behavior.
The two PDAC lines, PANC1 and AsPC1, both resemble the majority genotype of pancreatic cancers in having activated KRAS and mutant p53 [56 (link)]. Moreover, CDKN2A is epigenetically down-regulated in both cell lines [57 (link), 58 (link)]. The CPI-613-resistant member of this pair, AsPC1, was isolated from a post-treatment metastasis [59 (link)]; whereas, CPI-613-sensitive PANC1 was isolated from an untreated primary tumor [56 (link), 60 (link)]. AsPC1 displays SMAD4 loss, as do the majority of clinical PDACs (whereas PANC1 retains SMAD4 expression) [61 (link)]. Collectively, these features are consistent with AsPC1 being a useful model for difficult-to-treat clinical PDAC cases more generally.

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.
