“…In these tumours, MYC expression was associated with elevated Rev-erbα and Odc1 and suppressed Bmal1 (Fig. 2d), while Per2 was suppressed by MYC, consistent with previous findings that MYC can suppress Per expression in some models15.…”

“…However, the response of other clock genes, such as Per2, to MYC may be context-dependent15. It is also notable that in contrast to Shostak et al .,2 who observed downregulation of REV-ERBα in the presence of ectopic MYC, we previously did not observe downregulation of REV-ERBα in control experiments with activation of MYC-ER Δ106-143 (ref.…”

“…While whether altered MYC expression in cancer could be mechanistically related to deregulated circadian rhythm either directly or indirectly remains to be established. While E-box elements exist in MYC gene itself [212], MYC and MYC-target genes have been demonstrated to be regulated by CLOCK-BMAL1 at both transcriptional and posttranscriptional levels in mammals [213,214]. Of note, the circadian repressor CRY2 promotes ubiquitylation and degradation of the MYC protein, suggesting that circadian disruption might promote tumorigenesis in part through MYC protein stabilization [215].…”

“…c-MYC expression can be regulated by E-boxes in its own promoter and by core clock proteins (74, 75). Additionally, it can also be regulated at the posttranslational level (76), with a very recent study indicating that the circadian repressor protein CRY2 targets MYC for degradation via the F-box protein FBXW7 (77). Thus, a negative cross talk between the MYC pathway and circadian oscillator is likely to exist in cancer cells.…”

Circadian clocks are innate oscillators that drive daily rhythms in metabolism, physiology, and behavior. 24-h rhythms in gene expression, driven by core clock transcription factors, reflect the epigenetic state of the cell, which in turn is dictated by the metabolic environment. Cancer cells alter their metabolic state and gene expression and therefore are likely to tweak circadian clock function in their favor. Over the past decade, we have witnessed an extraordinary increase in systems-level studies that suggest intricate mechanistic links between the cellular metabolome and the circadian epigenome. In parallel, reprogramming of cellular clock function in cancers is increasingly evident and the role of clock genes in the development of hematological tumors, as well as their pathophysiological effects on tissues distal to the tumor, has been described. Furthermore, the interplay between components of the circadian clock, metabolic enzymes, and oncogenes is starting to be better understood, such as the close association between overexpression of the Myc oncogene and perturbation of circadian and metabolic rhythms, thus opening new avenues to treat cancers. This review article explores current knowledge on the circadian metabolome and the molecular pathways they control, with a focus on their involvement in the development of hematopoietic malignancies.
