CRISPR/Cas9-Mediated Knockout of AMPK and ATF4

Check if the same lab product or an alternative is used in the 5 most similar protocols
Knockout of AMPK α1/α2 and ATF4 in UMRC6 cell line was done by using sgRNAs and CRISPR/Cas9 technology as follows. The sgRNAs were cloned into the lentiviral lentiCRISPR v2 vector. A LentiCRISPR v2 vector containing sgRNAs against ATF4 was described in our previous publication (30 (link)). All constructs were confirmed by DNA sequencing. pGIPZ-shRNAs against BMI1 were obtained from the Functional Genomics Core at The University of Texas MD Anderson Cancer Center. Other reagents were purchased as follows: 2-deoxy-D-glucose (2DG; D6134), metformin (PHR1084), phenformin (P7045), tunicamycin (T7765), and N-acetyl-cysteine (A7250) from Sigma; A-769662 (LC laboratories, A-1803); 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR; ThermoFisher Scientific, A611700); ISRIB (Apexbio, B3699); brefeldin A (Cayman Chemical, #11861); thapsigargin (Santa Cruz, sc-24017A); PRT-4165 (Abcam, ab146003); BAY-876 (Sigma, SML1774); SP600125 (Selleckchem, S1460); and SB203580 (Selleckchem, S1076).

Check if the same lab product or an alternative is used in the 5 most similar protocols
For bacterial CaMMK2.1 expression, the human DNA sequence for truncated CaMKK2.1 (156–588), encompassing the kinase domain, was generated with a NH2-terminal GST-tag (PreScission cleavable) and COOH-terminal 6xHis-tag and cloned into pGEX-6P-1 using NdeI/BamHI restriction sites by Gene Universal (Newark, Delaware, United States). Other plasmids used in this study have been described previously [14 (link),41 (link)]. pMT2-HA-γ1-R299G mutant construct was generated from pMT2-HA-γ1 [41 (link)] by site-directed mutagenesis using QuikChange site-directed mutagenesis kits (Stratagene) and sequence verified. MK-8722 (AOB33226) and PF-739 (AOB33584) were from AOBIOUS. AMP (A1752), ADP (A2754), ATP (A2383) and phenformin (P7045) were from Sigma–Aldrich.

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.
