KLF4 and neoplasm: Moreover, reduced tumor cell metabolism (e.g., as exemplified by low HMGCR or LDHA expression) was also associated with adverse outcomes, with high expression ratios of KLF4 to HMGCR (HR = 3.47; 95% CI, 1.61-7.48; P = 0.02) (Figure 7E) and KLF4 to LDHA (HR = 3.74; 95% CI, 1.66-8.43; P = 0.001) (Figure 7F) prognostic of poor 3-year survival rates.
