Regarding LSD1, only 15 cases (17.86%) exhibited no or weak immunopositivity, 32 cases (38.10%) exhibited moderate immunopositivity, and 37 cases (44.05%) exhibited strong immunopositivity in the tumor tissues (Figure S9F), suggesting LSD1 expression in the HCC tissues was predominantly upregulated in comparison with NATs (Figure S9G). Here, KDM1A is linked to neoplasm.
