Introduction: Papilloedema can be the first sign of life-threatening disease, for example, brain tumours. Due to the potential seriousness of this clinical sign, the detection of papilloedema would normally prompt urgent hospital referral for further investigation. The problem is that many benign structural variations of optic nerve anatomy can be mistaken for papilloedema, so-called pseudopapilloedema.

One of the key events in DNA damage response (DDR) is activation of checkpoint kinases leading to activation of ribonucleotide reductase (RNR) and increased synthesis of deoxyribonucleotide triphosphates (dNTPs), required for DNA repair. Among other mechanisms, the activation of dNTP synthesis is driven by derepression of genes encoding RNR subunits RNR2, RNR3, and RNR4, following checkpoint activation and checkpoint kinase Dun1p-mediated phosphorylation and inactivation of transcriptional repressor Crt1p. We report here that in the absence of genotoxic stress during respiratory growth on nonfermentable carbon source acetate, inactivation of checkpoint kinases results in significant growth defect and alters transcriptional regulation of RNR2-4 genes and genes encoding enzymes of the tricarboxylic acid (TCA) and glyoxylate cycles and gluconeogenesis.
