“…Altogether, these interconnected elements drive and ensure the robustness of 24 h rhythmic oscillations in the expression of various additional target genes also known as clock-controlled genes (CCGs) ( Figure 2B ). CCGs are involved in various cellular mechanisms, including metabolism ( Eckel-Mahan and Sassone-Corsi, 2013 ; Fuhr et al, 2018 ; Reinke and Asher, 2019 ; Sato et al, 2022 ), RNA processing ( El-Athman et al, 2018 ; Yeung et al, 2018 ; El-Athman et al, 2019 ), cell cycle ( Shostak et al, 2016 ; El-Athman et al, 2017 ; Farshadi et al, 2020 ), DNA damage response ( Ando et al, 2001 ; Sancar et al, 2010 ; Preußner et al, 2017 ), and apoptosis ( Lee and Sancar, 2011 ), which are often dysregulated in the context of pathological development. The circadian clock has also been reported to directly modulate the cell cycle via regulation of checkpoints such as Myc ( Altman et al, 2015 ; Shostak et al, 2016 ), Wee1 ( Matsuo et al, 2003 ), p21 ( Gréchez-Cassiau et al, 2008 ), and p16 ( Kowalska et al, 2013 ; El-Athman et al, 2017 ).…”
