    MYC regulates ASS1 expression in the context of BRAF/MEK inhibition . ( a and b ) Melanoma cells were treated with Dabrafenib/Trametinib (D/T) for 5 days. Total mRNAs were isolated and subjected to qPCR to detect the mRNA expression of ASS1 and MYC ( a ). The same treatment was performed, protein lysates were collected, and ASS1 and MYC protein expression were detected by western blot ( b ). β-ACTIN was used as a loading control. ( c-f ) Non-targeting sgRNA (sgNT) or sgRNAs targeting MYC (sgMYC) were designed, cloned <t>to</t> <t>lentiCRISPRv2-blasticidin</t> vector, used to package lentivirus, and infect target melanoma cells. After blasticidin selection, total mRNAs from survived cells were isolated and subjected to qPCR to quantify mRNA expression of ASS1 ( c ), while protein lysates were collected and used for western blot to detect protein expression of ASS1 and MYC ( d ). sgAss1 was used as a positive control. β-ACTIN was used as a loading control. Meanwhile, blasticidin resistant cells were seeded onto 6-well plates, treated with PBS or ADI-PEG20 for 10 days, and crystal violet was used to stain colonies formed. Representative images were shown ( e ) and area percentage of stained colonies were quantified ( f ).
