Generating Bortezomib-Resistant Myeloma Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
The human multiple myeloma cell lines MM.1S, MM.1R, OPM1, RPMI8226/Dox, and NCIH929 were purchased from ATCC Company. Cells were grown in suspension in RMPI1640 medium supplemented with 10% fetal bovine serum, 1% (v/v) penicillin, and 100 μg/mL streptomycin. Cells were maintained at 37 °C in a 5% CO2 atmosphere with a proper humidity.
To generate bortezomib-resistant myeloma cell lines, bortezomib (BTZ) was added to the multiple myeloma cell culture medium starting at 0.03 nM. The culture medium was replaced with bortezomib containing medium twice weekly and the myeloma cells were cultured for 2–4 weeks until the cells survived and became resistant to that concentration of bortezomib. The bortezomib concentration was then increased by doubling the previous concentration until BTZ reached at a final concentration of up to 8.4 nM by the end of the second year. Myeloma cell lines were maintained on BTZ containing medium until 1 week before experiments.

RPMI-8226, NCI-H929, U266, HEK293T/17 and HS-5 were purchased from ATCC. KMS-11 and MOLP-8 were a kind gift from Professor H. Johnsen (Aarhus University Hospital, Denmark). GFP-tagged bone marrow stromal cells, HS-5-GFP, were generated as previously described [29 (link)]. HEK293T/17 and HS-5-GFP cells were cultured in DMEM containing GlutaMAX™ and 10% FBS (Life Technologies). All other cells were cultured in RPMI-1640 containing GlutaMAX™ and 10% FBS. All cells tested negative for mycoplasma by PCR and were authenticated by STR analysis.

Cell Line Collection and Preparation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cell lines (Hs-578T, ZR-75-1, MCF-7, MCF-7/HER2, MCF10A, Raji, Ramos, NCI-H929, BCBL-1, ES-2, NCI-H358, A549, C-33A, CaSki, and HeLa) were obtained from ATCC. Cell cultures were performed using the ATCC-recommended growth media, subcultivation ratios, and medium renewal interval (available online at www.atcc.org).
During cell harvest, in order to preserve membrane glycoprotein integrity, cells were scraped rather than enzymatically lifted. For each cell sample, approximately 10 million cells were counted and collected. Duplicate samples were collected from the lymphoma (Raji; Ramos; NCI-H929; BCBL-1), cervical carcinoma (33A; CaSki; HeLa), and lung carcinoma (NCI-H358; A549) cell cultures; however, due to cell growth limitations, only single samples were collected from the breast (Hs-578T; ZR-75-1; MCF-7; MCF-7/HER2; MCF10A) and ovarian (ES-2) cell cultures.

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.
