Inhibition of human interferon-gamma expression by antisense oligodeoxynucleotides. 1994

We investigated 12 antisense oligodeoxynucleotides, complementary to different regions of the human interferon-gamma (HuIFN-gamma) gene, for their ability to inhibit HuIFN-gamma production in cultures of single donor total leukocytes or lymphocytes (95% purity). Out of seven oligomers, specific for a sequence including the translation initiation codon, 15 to 21 nucleotides long, the one resulting in the greatest inhibition was the 16-mer. An inhibitory effect of 90% could be achieved when the oligomer was added to cultures of lymphocytes in separate doses. Three other 16-mers, complementary to a sequence in the 5' noncoding region, in the coding region, or at the donor splice junction of the third intron respectively, were inhibitory to a lesser extent. Two 16-mers, one complementary to a sequence at the donor splice junction of the second intron and one specific for a sequence in the 3' untranslated region, showed no effect.

UI	MeSH Term	Description	Entries
D007371	Interferon-gamma	The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.

D007700	Kinetics	The rate dynamics in chemical or physical systems.
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
