Tumour necrosis factor-alpha (TNF-alpha) is a potent pro-inflammatory agent produced primarily by activated monocytes and macrophages. TNF-alpha is synthesized as a precursor protein of M(r) 26,000 (26K) which is processed to a secreted 17K mature form by cleavage of an Ala-Val bond between residues 76-77. The enzyme(s) responsible for processing(More)
In vitro splicing of human beta-globin pre-mRNA can be fully inhibited by treatment of the splicing extract with polyclonal antibodies against hnRNP core proteins prior to the addition of pre-mRNA. Inhibition of the first step in the splicing pathway, cleavage at the 5' splice site and lariat formation, requires more antibodies than inhibition of the second(More)
Transfection of U937 and THP-1 cells with a recombinant plasmid, pIL1(4.0kb)-CAT, containing 4 kb of the interleukin 1 beta (IL-1 beta) gene upstream regulatory sequence resulted in inducer-dependent expression of chloramphenicol acetyltransferase activity. Treatment of the transfected cells with various combinations of the inducers lipopolysaccharide,(More)
