title: Overexpression of the PDCD2-like gene results in inhibited TNF-alpha production in activated Daudi cells.
abstract: Both PDCD2 and PDCD2-like proteins have PDCD2_C terminal domains, but their functions are still unclear. After analysis of their expression in Gene Expression Omnibus, we hypothesized that they played a role in inflammation. In Daudi cells exposed to lipopolysaccharides, PDCD2-like RNA was upregulated, whereas PDCD2 was downregulated. Overexpression of PDCD2-like gene effectively attenuated tumor necrosis factor (TNF)-alpha release but elevated interleukin (IL)-6 and PDCD2 expression induced by lipopolysaccharide (LPS). It is possible that both proteins have anti-inflammatory effects like IL-6. The results have implications for understanding the function of PDCD2/PDCD2-like proteins and may help in the development of novel anti-inflammatory drugs.
