MMTV-PyMT-S2WTP3 cells were infected with lentiviral particles expressing the pHAGE-deltaOA-zsGreen plasmid as previously described6 (link), and infected cells were isolated by FACS.
MDA-MB-453 and BT474 cells were transient transfected with pBabepuro3-p16Flag (Addgene Cat # 24934) using Lipofectamine 3000 (Thermo Fisher) according to the manufacturer’s instructions. 72 hours after transfection cells were selected in puromycin for 48 hours. p16 overexpression was confirmed by anti-FLAG western blots.
For overexpression of DNMT1, MDA-MB-453 cells were transfected with the pcDNA3/Myc-DNMT1 vector (Addgene Cat #36939) using Lipofectamine 3000 according to the manufacturer’s instructions. Cells were treated with abemaciclib 72 hrs after transfection.

Inducible p16 and p21 Overexpression

For Tet‐inducible overexpression of p16INK4a and p21Cip1 in human primary fibroblasts we used a two‐component transposon system (Figure S1). First, the puromycin resistance gene with a preceding 2A site was integrated into the transposable region of the tet‐controllable transposon plasmid pTOV‐11. This DNA fragment was amplified from the vector pSpCas9n(BB)‐ 2A‐Puro (PX462) V2.0 (Addgene #62987). This was followed by integration of the sequence into the target vector via restriction digestion by BamHI and Crf9I. Integration of the p16INK4a or p21CIP1 cDNA into the target vector followed in another cloning step. The cDNA was amplified from vectors pBabepuro3‐p16Flag (Addgene #24934) and Flag p21 WT (Addgene #16240) and integrated into the transposon vector via NotI and SalI restriction sites.

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.
