Establishing Tetracycline-Inducible SMARCB1 Cell Line and CRISPR-Cas9 Engineered Renal Tumor Model
mIMCD-3 (mouse inner medulla collecting duct) mouse cell lines were purchased from ATCC. RMC219-Tet-inducible SMARCB1 cell line: The tetracycline-inducible pIND20-fSNF5-HA vector (35 (link)) was kindly donated by Bernard E. Weissman. The pInducer20 empty backbone (36 (link)) was a gift from Stephen Elledge (Addgene plasmid # 44012). Lentivirus was generated in HEK-293T cells and used to generate stable tet-inducible cell lines as previously described (37 (link)). RMC219 (also called JHRCC219), a human tumor cell line that was established in a previous study (23 (link)), was infected with tetracycline-inducible pIND20-fSNF5-HA vector. Cells were treated with 2 μg DOX for 3 d to reconstitute SMARCB1 (SNF5). MSRT1 (Melinda Soeung renal tumor 1) was generated using CRISPR-Cas9 gene editing technology as described in SI Appendix, Figs. S2 and S3 and Supporting methods.

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.
