In addition to its apparent link to diabetes, GLDC gene expression has been shown to be elevated in many cancers, including non‐small cell lung cancer (Zhang et al., 2012), breast cancer (Kwon et al., 2014), glioblastoma multiforme (Kim et al., 2015), and prostate adenocarcinoma (Woo et al., 2018). The gene discussed is GLDC; the disease is glioblastoma.
