Check if the same lab product or an alternative is used in the 5 most similar protocols
C2C12 and HEK293T cells were obtained from the American Type Culture Collection (ATTC, Masnassas, Virginia) and analyzed for potential myoplasma contamination every two month using the PCR Mycoplasma Test Kit I/C from Promocell (Heidelberg, Germany). Identity of C2C12 cells was authenticated by induction of myotube differentiation. Antibodies recognizing BRAF, EEA1, LAMIN A/C and MYOGENIN were obtained from BD Biosciences (San Jose, California) while PAX3, MYOD and myosin heavy chain antibodies (MHC) were from the Developmental Studies Hybridoma bank (Iowa City, Iowa). Additional PAX3 and anti-LBX1 antibodies were purchased from Abcam (Cambridge, Massachusetts). Anti-phospho-PAX3 (Serine 205) was a kind gift of Dr. A. D. Hollenbach (Miller et al., 2008 (link)). The antibody against CD31 and recombinant Scatter Factor/Hepatocyte Growth factor (HGF) was obtained from R and D Systems (Minneapolis, Minnesota). Anti-phospho BRAF, anti-phospho ERK1/2 and anti-GAPDH antibodies were purchased from Cell Signaling (Danvers, Massachusetts). Anti-MYF5 was from Santa Cruz (Dallas, Texas) and Anti-GST was from GE healthcare (Chicago, Illinois).

Check if the same lab product or an alternative is used in the 5 most similar protocols
The human Müller cell line MIO-M1 was obtained from the UCL Institute of Ophthalmology (London, United Kingdom; ref. 51 (link)). PMCs from mitoQC+/+ mice were isolated and cultured as previously described (25 (link)). PMCs were used for experiments from P2–P6, where most cells showed a senescence phenotype. Cultures were maintained in DMEM (containing 10% FCS [Thermo Fisher Scientific], 100 U/mL penicillin-streptomycin [Sigma-Aldrich]) and supplemented with 5.5 mM D-glucose (NG), 30.5 mM D-glucose (Sigma-Aldrich; HG), or 30.5 mM LG (Alfa aesar; 25 mM LG + 5.5 mM NG) for 5 days. The selection of 30.5 mM D-glucose was based on the levels of hyperglycemia found in the plasma of Ins2Akita/+ mice. For mitophagy-induced amino acid starvation, cultures were maintained in HBSS (Thermo Fisher Scientific; 16 hours). Autophagy flux was blocked with 100 μM chloroquine (12 hours). Endpoint experiments were performed in 70%–80% confluent cultures. No mycoplasma was detected in the cell cultures (PCR Mycoplasma Test Kit I/C; PromoCell).

B6 mESCs used in this study were established and maintained in 2i/LIF medium as described in Pryzhkova and Jordan, 2016 (link); Pryzhkova et al., 2020 (link). mESCs were verified to be negative for mycoplasma using the PCR Mycoplasma Test Kit I/C (PromoCell). For cell growth analysis mESCs were cultured in the presence of 10 µM CHEK2 inhibitor II (Cayman), 3 µM CHEK1 inhibitor LY2603618 (Cayman), or p53 inhibitor cyclic pifithrin-alpha hydrobromide (Cayman), with or without 100 µM IAA for 48 hr. Drugs were added 18–20 hr after passaging. mESCs were counted at the time of passaging and after 48 hr of growth in the presence of drugs.

Isolation and Culture of Cardiac Perivascular Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cardiac PCs were immunosorted as CD31neg/CD34pos cells from human myocardial samples, and expanded in a dedicated medium supplemented with human recombinant growth factors and 2% v/v foetal calf serum (FCS) (ECGM2 complete kit, C-22111, PromoCell) as previously described [11 (link),28 (link)]. Briefly, samples were finely minced using scissors and scalpel until nearly homogenous and digested with Liberase (Roche) for up to 1 h at 37 C, with gentle rotation. The digest was passed through 70-, 40-, and 30-μm strainers. Finally, the cells were recovered and sorted using anti-CD31 and -CD34 microbeads (Miltenyi) to deplete the population of CD31pos ECs and select CD31neg/CD34pos cells, which distinguish a population of perivascular cells in situ [11 (link),28 (link)]. After expansion to passage 3, the purity of the cell population was verified using immunocytochemistry (ICC) or flow cytometry [11 (link),28 (link)].
Human coronary artery ECs (CAECs) were purchased from PromoCell and expanded in the same medium used for PCs. All cells used in the present study tested negative for mycoplasma contamination (assessed using the PCR Mycoplasma Test Kit I/C, PromoCell, cat# PK-CA91-1096). Cells were used between passages 4 and 7.

Characterization of B16F1 GFP Melanoma Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
B16F1 GFP cells [18 (link)] carry deletions of exons 1α, 1β, and 2 of the Ink4a/Arf gene locus, resulting in loss of p16Ink4a and p19Arf protein expression and altered p53 protein expression without detectable gene mutations, however with no activating BRAF mutations in exons 11 and 15 [19 (link)]. B16F1 cells were grown in DMEM medium (+4.5 g/L D-Glucose, L-glutamine, Thermo Fisher Scientific, Darmstadt, Germany) supplemented with 10% FCS, 2 mM L-glutamine, 100 U/mL penicillin, and 100 µg/mL streptomycin. Cells were counted using a Neubauer cell counting chamber (Laboroptik, Friedrichsdorf, Germany). Cells were routinely tested negative for mycoplasma (PCR Mycoplasma Test Kit I/C; PK-CA91-1096; Promocell, Heidelberg, Germany). For coating, the recombinant proteins (acid extracted Bovine Collagen Type I, Curacyte Discovery GmbH, Leipzig, Germany; human fibronectin, Roche Life Science, Penzberg, Germany) were diluted in PBS and incubated overnight at 4 °C.

Target cells including K562 and melanoma cell lines were kept in culture for 2–3 months (24–30 passages). The leukemia cell line K562 (ATCC, #CCL-243) was cultured in RPMI1640 medium (Thermo Fisher Scientific, #21875–034) supplemented with 10% FCS. Melanoma cell lines were maintained in melanoma growth medium [TU2%, consisting of 80% MCDB153-Basalmedium (Biochrom AG, #F 8105), 20% L-15, Leibowitz-Medium (PromoCell, #C-24300), 2% FCS, 1.68 mmol/L CaCl2 (Sigma-Aldrich, #21115), 5 ng/mL human insulin (Sigma-Aldrich, #I9278)]. The 1205Lu cell line was cultured in TU2% with 200 mmol/L L-glutamine and without insulin. The 15 melanoma cell lines used in this study have been provided, authenticated, and documented by the Herlyn laboratory (Wistar Institute, Philadelphia, PA; see Supplementary Table S1 and Resources at https://wistar.org/our-scientists/meenhard-herlyn). All cell lines were regularly tested for Mycoplasma contamination by using PCR Mycoplasma Test Kit I/C (PromoCell #PK-CA91–1024) according to the manufacturer’s manual. Protein expression in melanoma cells was manipulated by using siRNA or DNA transfection or by CRISPR-Cas9. Immunoblotting, IHC, immunofluorescence, and flow cytometry were applied to determine protein abundance. For full description of the methods used, please see Supplementary Data.

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.
