Herein, depletion of SLC7A11-AS1 had an effect on c-Jun and cyclin D1 overexpression that was related to tumor cell cycle progression, indicating that SLC7A11-AS1 regulated cell cycle and proliferation cause to SLC7A11 up-regulation by the c-Jun N-terminal kinase (JNK) and p38 pathways. This evidence concerns the gene CCND1 and neoplasm.
