Bone marrow derived cell lines, MEG-01 (ATCC, CRL-2021) and HEL92.1.7 (ATCC, TIB-180) were grown in RPMI 1640 media and kept at 37 °C in 5% carbon dioxide (CO2) incubator. Chinese hamster ovary (CHO)-K1 cells (ATCC, CCL-61) and human embryonic kidney (HEK293) cells (ATCC, CRL-1573) were cultured in DMEM media and kept in a 5% CO2 incubator at 37 °C. ADRA2B-HEK293 cells were stably transfected with pcDNA3.1(+)-ADRA2B-N-DYK and G418-resistant cell pool expanded after being selected with G418 (1.5 mg/ml). Unless otherwise stated, all culture media were supplemented with fetal bovine serum (FBS; 10%), penicillin (100 U/mL) and streptomycin (100 μg/mL). β2-HEK293 were cultured as previously described (Watson et al., 2016 (link)). Before use, all cell lines used were tested to confirm negative status for mycoplasma (CC cell culture facility).

The human chronic myelogenous leukemia cell line K562 (Cat No. CCL-243; ATCC) and human erythroleukemia cell line HEL 92.1.7 (Cat No. TIB-180; ATCC) were obtained from the American Type Culture Collection. Both the cells were grown in RPMI 1640 medium (Gibco) supplemented with 10% FBS (Sigma-Aldrich), gentamicin (1,000x, Cat No. 15-710-072; Thermo Fisher Scientific), Pen-Strep-Neo solution (100x, Cat No. 15640-055; Thermo Fisher Scientific), and 2 mM L-glutamine at 37°C in a humidified 5% CO2 atmosphere. 5-Aminolevulinic acid hydrochloride (ALA), purchased from Alfa Aesar (Cat No. A16942ME), was dissolved in distilled water to yield a stock concentration of 1.0 M, and stored at −20°C. Glycine, purchased from Thermo Fisher Scientific (Cat No. BP381-500), was dissolved in phenol red–free culture medium purchased from Gibco (Cat No. 11835055) to give a stock concentration of 1 M.

We obtained the following: human umbilical vein endothelial cells (HUVECs), human coronary artery endothelial cells (HCAECs), normal human cardiac fibroblasts-ventricular (NHCF-V) cells, human erythroleukemia (HEL 92.1.7), and human neuroblastoma cells (SK-N-FI) from the American Type Culture Collection (ATCC). The human embryonic stem cell-derived cardiomyocytes (hESC-CMs) were differentiated from the Wicell H7 line. The hiPSC-derived neurons were provided by Dr. Thomas Sudhof (Department of Molecular and Cellular Physiology, Stanford University). TNFα and genistein treatment of hiPSC-ECs were performed on hiPSCs from healthy control line 1 or CRISPRi knockdown of CNR1. The hiPSCs were differentiated into hiPSC-ECs and treated with vehicle, 10 ng/ml TNFα, or 10 μM genistein. Gene expression was quantified using quantitative real-time PCR (qRT-PCR).

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.
