Changes of gene expression in T lymphocytes following Golli‑MBP gene RNA interference.

The major cell types expressing Golli in the immune system are the T‑lineage cells. The aim of the current study was to investigate the changes of gene expression in T lymphocytes subsequent to downregulation of the Golli‑myelin basic protein (MBP) gene. RNA interference technology was used to suppress the expression of Golli‑MBP in Jurkat cells and DNA microarray techniques were applied to investigate the alterations of gene expression profiles. The results indicated that there were 387 differentially expressed genes. In the Golli‑MBP knockdown Jurkat cells, the expression of 108 genes was enhanced, 279 genes were suppressed. Gene ontology analysis identified differentially expressed genes involved in several biological progresses, including cell adhesion and immune responses. Pathway analysis demonstrated that the majority of the differentially expressed genes (23.3%) were involved in cytokine‑cytokine receptor interaction. Subsequent to Golli‑MBP knockdown, the mechanisms that changed the biological characteristics of Jurkat cells were complex, involving numerous types of functional proteins, and metabolic and signaling pathways. However, further experiments are required to confirm these results.
