LENG8 and neoplasm: By promoting the expression of PD-L1, MYOSLID indirectly supports tumor immune evasion mechanisms; conversely, other lncRNAs, such as STAG3L5P-PVRIG2P-PILRB (Stromal Antigen 3-Like 5 Pseudogene-Poliovirus Receptor-Related Immunoglobulin Domain-Containing 2 Pseudogene-Paired Immunoglobulin-Like Type 2 Receptor β) and LENG8-AS1 (Leukocyte Receptor Cluster Member 8 Antisense RNA 1), exhibited a negative correlation, implying reduced activity as PD-1 levels increased.
