This Hubble image shows NGC 1866, a massive globular cluster located in the constellation Dorado, some 160,000 light-years away. The image was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Five filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble.

Model of TH5487-mediated inhibition of proinflammatory gene expression: inflammation, at its onset and throughout its progress, is associated with generation of reactive oxygen species, causing damage to DNA in particular at guanine-rich promoters; OGG1 binding to oxidized guanines at promoter regions facilitates recruitment of downstream transcription factors that drive proinflammatory gene expression, and a cellular inflammatory response; in the presence of TH5487, OGG1 can no longer interact with DNA substrates in promoters, so proinflammatory gene expression is inhibited, and the cellular inflammatory response is prevented.
