CLOCK and acute myeloid leukemia: Although no significant correlation between PRC2m and chronological age in AML patients was detected (Figure 4A), PRC2m was negatively correlated with DamAge (partial r< −0.5) and positively correlated with EA value of Pan‐tissue clock, CasuAge, and AdaptAge (partial r >0.5, Figure 4D–G), whilst controlling the effects of chronological age.
