Although acetylsalicylic acid does not itself induce interferon, acetylsalicylic acid was found to significantly enhance the production of both human alpha interferon and human gamma interferon when added with the appropriate inducers to cultures of human peripheral blood mononuclear cells. The mechanisms associated with this effect were investigated.

To determine the chromosomal location of the human alpha interferon genes, we scored a series of human/rodent somatic cell hybrids for the presence of DNA sequences hybridizing to an alpha 1 interferon DNA probe. The presence of human chromosome 9 in a hybrid correlated with the presence of a family of alpha interferon genes.

Type I interferon (IFN-I) mediated innate immune response controls virus infections by inducing the expression of interferon stimulated genes (ISGs). Although ubiquitination plays key roles in immune signaling regulation, a human genome-wide understanding of the role of E3 ubiquitin ligases in interferon mediated ISG induction is lacking. Here, we report a genome-wide profiling of the effect of...

Human lupus is strongly associated with a gene expression signature characterized by over-expression of Type I interferon-regulated genes. A strong interferon signature generally is not seen in the standard mouse models of lupus, despite considerable evidence for the involvement of toll-like receptor-driven interferon production. In contrast, pristane-induced lupus exhibits a prominent TLR7-dep...

the objective of this research was to investigate the influence of the over-expression of recombinant interferon-g during high cell density cultivation on cellular characteristics of recombinant e. coli. batch and fed-batch culture techniques were employed to grow escherichia coli bl21 for production of human gamma-interferon in pet expression system. final cell densities in batch and fed-batch...

A total of 40 mouse-human cell hybrids were induced with poly(I).poly(C) and with Newcastle disease virus. Ten hybrid clones produced low levels of human interferon in response to both the virus and poly(I).poly(C). Concurrent enzymic and chromosomal analysis of the hybrid clones indicated a concordant segregation of these levels of human interferon with chromosomes 2 and 5. The presence of bot...

We investigated the effect of tamoxifen, 4-OH tamoxifen, toremifene droloxifene, interferon-alpha2a, interferon-alpha2b and interferon-alpha2c, singly and in combination, for their effect on nitric oxide production by MCF-7 and ZR-75-1 human breast cancer cells. Tamoxifen and 4-OH tamoxifen singly had no effect on nitric oxide production by either cell line. However, treatment with droloxifene ...

Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....
