LOXL4 and glioma: Considering some previous investigations illustrating that LOXs, especially, LOX, LOXL1, and LOXL4 are closely associated with immunity (Tenti and Vannucci, 2020; Li et al., 2021; Tan et al., 2021), finally contributing to tumor progression, we would like to explore whether LOXs expressions were correlated with glioma immunity.
