MACROH2A1 and colonic neoplasm: High macroH2A1.1 mRNA ratios in the slow cycling claudin-low molecular subtype [31] are correlated with earlier observations that macroH2A1.1 expression may be restricted to non-proliferative tissues [42], and that loss of its expression in lung and colon cancer was related to enhanced cell proliferation of cancer cells [24]–[26].
