WebIn the present study, we report that the core clock genes Bmal1 and Clock play a pro-proliferative role in HCC by controlling cell cycle regulators. Down-regulating Bmal1 and Clock induced HCC cytotoxicity, activated … We then explored how depletion of BMAL1 affects end-resection. As chromatin remodeling regulated by histone modification, in particular acetylation of Histone H4 (H4Ac), is critical for DNA end-resection in eukaryotes and HR-mediated DSBs repair [12, 42, 43]. CLOCK has an intrinsic acetyltransferase domain … See more To find out whether BMAL1 directly participates in DSBR, human sarcoma U2OS cells were treated with Zeocin, a radio-mimetic chemical that predominantly induces DSBs [22, … See more DNA end-resection is the key event that controls the DSB repair pathway choice, which generates the long ssDNA leading cells prone to HR-mediated repair [37]. Because BMAL1 … See more We then explored how depletion of BMAL1 affects DSBR. BMAL1 was knocked down in U2OS, the amount of DSBs was determined by detecting DNA fragments released by DSBs and the level of phosphorylation of … See more It is well recognized that cancer cells that are deficient in HR-mediated DSBR are frequently more sensitive to killing by chemotherapy drugs such as etoposide or irradiation than the … See more
WebApr 22, 2008 · Circadian oscillation of clock-controlled gene expression is mainly regulated at the transcriptional level. Heterodimers of CLOCK and BMAL1 act as activators of target gene transcription; however, interactions of PER and CRY proteins with the heterodimer abolish its transcriptional activation capacity. PER and CRY are therefore referred to as … WebMay 1, 2024 · Bmal1 and Clock. Bmal1 and Clock, the positive elements of the main TTFL in circadian clock, are indispensable for generating circadian gene expression (Takahashi, 2024). Bmal1 and Clock have …
Web1 day ago · It can also bind to CLOCK/BMAL1 complexes, which alters the expression of other associated genes, such as PER, in a manner that is probably related to the variable concentration of its co-enzyme, NAD+ . In addition, the existence of circadian rhythms independent of the canonical molecular clock has been demonstrated. Specifically, there …
