Investigation of the anti-tumour properties of interferon epsilon in high grade serous ovarian cancer in vivo.

ABSTRACT: This experiment is part of a larger study examining the anti-tumour properties of interferon epsilon in ovarian cancer. The goal of this experiment was to test the direct effects of interferon epsilon and interferon beta on human ovarian tumours in vivo, using patient derived xenografts (PDX) in immunocompromised (NSG) mice.
Project description:This experiment is part of a larger study examining the anti-tumour properties of interferon epsilon in ovarian cancer. The objective of this experiment was to examine the direct activity of interferon epsilon on the mouse ovarian cancer cell line, ID8, and compare it to equivalent unit concentrations of interferon beta. The goal was to determine whether interferon epsilon and interferon beta induce different patterns of gene expression in ID8 cells.
Project description:This experiment is part of a larger study examining the anti-tumour properties of interferon epsilon in ovarian cancer. The goal of this experiment was to assess whether interferon signalling had been ablated in Ifnar1 CRISPR knockout (KO) ID8 cell lines, so that they could be used for in vivo models of ovarian cancer.
Project description:The female reproductive tract (FRT) is vulnerable to sexually transmitted infections and therefore a well-tuned immune surveillance system is crucial for maintaining a healthy FRT. However, our understanding of the factors that impact viral infection of the FRT and the host response are not well understood. In this work, we investigate the role of a hormonally regulated type I interferon, IFN epsilon, in control of Zika virus (ZIKV) infection of the FRT. We demonstrate that IFN epsilon has anti-ZIKV properties using a combination of IFN epsilon KO mice, blockade of endogenous IFN epsilon by neutralising Abs and rescue of IFN epsilon KO mice by recombinant IFN epsilon administered directly to the FRT.
Project description:The testis is susceptible to viral infections, which can impair fertility. Spermatogenic cells were thought to lack anti-viral defences, including interferon (IFN) or IFN-stimulated gene (ISG) expression. Challenging this dogma, we discovered that interferon-epsilon (IFNɛ), a type-I IFN first identified in female reproductive epithelia, is constitutively expressed by spermatogenic cells and macrophages in mouse and human testes. Moreover, mice lacking IFNɛ are more susceptible to viral epididymo-orchitis. The mechanisms of IFNɛ-mediated anti-viral protection in the testis were examined in this study.
