SLC7A2 and neuroblastoma: Previously, we knocked out normal HTT in human neuroblastoma SH-SY5Y cells using the CRISPR–Cas9 (clustered regularly interspaced palindromic repeats-CRISPR-associated protein 9) genetic editing approach and identified solute carrier family 7 member 2 (SLC7A2) as one of the most significantly upregulated genes by RNA-seq analysis [6].
