Figure Lengend Snippet: Data Supporting Figure 5. A , Immunoblot from lysates of A549 cells or SLC7A11 knockout clones for indicated proteins upon treatment with βMe (50μM). Inferred MW of band indicated. B , Viability (ATP) of cells from C cultured in the presence or absence of cystine (CySS) with indicated concentration of supplemented βMe for 3 days. Data report mean of technical triplicates. C , Viability (ATP) of A549 cells in cystine-free media or upon erastin treatment (10μM), or SLC7A11 knockout clones in standard conditions, treated with the indicated concentrations of reducing agents βMe, dithiothreitol (DTT), or Tris(2-carboxyethyl)phosphine (TCEP), 3 days. Data are the mean of two technical replicates. D , Viability (ATP, solid lines) and GSH content (dashed lines) of A549 cells cultured at indicated CySS concentration for 3 days. Data report mean of two technical replicates. E , Upper left, schematic delineating the contribution of serine-derived carbon to cysteine, glycine, GSH, or GSSG. Right, isotopic labeling of the indicated metabolites derived from A549 cells cultured in U- 13 C-serine (286 μM) as the only source of serine (top, GC-MS detection; bottom, LC-MS detection), in the presence or absence of CySS or βMe (50 μM) for 24 hr. ND = not detected. F , Crystal violet staining of A549 SLC7A11 knockout clones from upon transwell culture with A549 cells expressing pLentiCRISPRv2 or an SLC7A11 knockout clone, 3 days. Data are from one experiment. G , Immunoblot from lysates of A549 cells or SLC7A11 knockout clones for indicated proteins in the presence or absence of CySS, βMe (50 μM) of Fer-1 (10 μM) for 2 days. Inferred MW of band indicated. Data are from one experiment. H , Viability (ATP) of A549 cells upon treatment with Na2SeO3 and the indicated concentrations of reducing agents βMe, DTT, or TCEP, 3 days. Data are the mean ± SEM of n=3 biological replicates.
Article Snippet: Purified products were cloned by Golden Gate assembly into BsmBI-v2–digested pLentiCRISPRv2 (Cas9 libraries) or pRDA-550 (enAsCas12a libraries) using the NEBridge Golden Gate Assembly Kit (E1602L, New England Biolabs).
