LOXL2 and neoplasm: Depending on this research, LOXL2 was markedly increased in numerous tumors when analyzing paired (16 types of tumors) and unpaired (27 types of tumors) samples at the mRNA level and 10 tumor types of unpaired protein samples, which aligns with previous reports [20, 21], especially for liver, lung, breast, kidney, uterine, head and neck cancers.
