我试图在文档中突出显示特定“细胞因子”一词的术语。在文档中有几个这个词的例子。我试着这样做：Solr - 突出显示
http://localhost:8983/solr/Cytokine/select?q=cytokine&hl=true&hl.fl=content
在我得到的结果是：

{"title":"High Glucose Increases the Expression of Inflammatory Cytokine Genes in
Macrophages Through H3K9 Methyltransferase Mechanism","content":"Recent studies suggest that histone modification is one of the mechanisms
regulating inflammatory cytokine gene expression in hyperglycemic conditions.
However, it remains unknown how histone methylation is initiated and involved in
changes of inflammatory cytokine gene expression under high glucose (HG)
conditions. Our aim was to investigate whether H3K9 methylation was involved in
HG-induced expression of inflammatory cytokines in macrophages. Expression
profile of cytokine genes under hyperglycemia in THP-1-derived macrophages was
determined by human cytokine antibody array. Based on the results from the human
cytokine antibody array analyses, the H3K9me3 levels of 4 inflammatory cytokine
genes, including interleukin-6 (IL-6), IL-12p40, macrophage inflammatory
protein-1α (MIP-1α), and MIP-1β under HG were determined by ChIP assays.
Furthermore, the expression of these 4 inflammatory cytokine genes under either
HG or chaetocin (an inhibitor of SUV39H1 methyltransferase) exposure or
overexpression of SUV39H1 (a H3K9me3-specific methyltransferase) was analyzed by
quantitative polymerase chain reaction. Macrophages cultured in HG conditions
showed increased gene expression and decreased H3K9me3 levels of inflammatory
cytokine genes compared with macrophages incubated in normal glucose (NG)
culture. Inhibition of SUV39H1 with chaetocin in NG-treated macrophages also
increased the expression of IL-6, IL-12p40, MIP-1α, and MIP-1β. Furthermore,
inhibition of SUV39H1 with chaetocin in HG-treated macrophages further increased
the expression of these inflammatory cytokines. Contrarily, NG-treated
macrophages transfected with SUV39H1 plasmids show decreased expression of
inflammatory cytokines. Furthermore, overexpression of SUV39H1 in HG-treated
macrophages alleviated the expression of inflammatory cytokines under HG
conditions. Finally, HG also increases the expression of inflammation cytokines
in mouse bone marrow-derived macrophages. Our data demonstrated that HG increases
the expression of inflammatory cytokines in macrophages through decreased H3K9me3
levels, which was partly mediated by SUV39H1. Dysregulation of epigenetic histone
modification may be one of the underlying mechanisms for HG-induced inflammatory
cytokine expression in macrophages."}
