OGDHL and central nervous system cancer: We found that IL4I1 was highly expressed in glioma cell lines (LN018, LN215, LN229, and LN319), CYP1A1 was low expressed in glioma cell lines (LN215, LN229, LN319, and BS149), OGDHL was low expressed in LN018, and ASMT was lowly expressed in glioma cell lines (LN018, LN215, LN229, LN319, and BS149; Supplementary Figure S3B).
