Interestingly, multivariate survival analysis elucidated a significantly poorer prognosis in lung and gastric cancer when GLS/GLS2 expression was low/high compared to co-occurrence (high/high) or non-co-occurrence (low/low) (Figure 7b(iii,iv)), suggesting that a partial-co-occurrence of GLS/GLS2 may regulate cancer prognosis. This evidence concerns the gene GLS and cancer.
