Abstract
The old people often suffer from circadian rhythm disturbances, which in turn accelerate aging. Many aging-related degenerative diseases such as Alzheimer's disease, Parkinson's disease, and osteoarthritis have an inextricable connection with circadian rhythm. In light of the predominant effects of clock genes on regulating circadian rhythm, we systematically present the elaborate network of roles that clock genes play in aging in this review. First, we briefly introduce the basic background regarding clock genes. Second, we systemically summarize the roles of clock genes in aging and aging-related degenerative diseases. Third, we discuss the relationship between clock genes polymorphisms and aging. In summary, this review is intended to clarify the indispensable roles of clock genes in aging and sheds light on developing clock genes as anti-aging targets.

REV-ERB Agonist SR9009 Regulates the Proliferation and Neurite Outgrowth/Suppression of Cultured Rat Adult Hippocampal Neural Stem/Progenitor Cells in a Concentration-Dependent Manner. Cell Mol Neurobiol 2021; 42:1765-1776. [PMID: 33599915 DOI: 10.1007/s10571-021-01053-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Accepted: 02/01/2021] [Indexed: 01/06/2023]
Abstract
REV-ERBs are heme-binding nuclear receptors that regulate the circadian rhythm and play important roles in the regulation of proliferation and the neuronal differentiation process in neuronal stem/progenitor cells in the adult brain. However, the effects of REV-ERB activation in the adult brain remain unclear. In this study, SR9009, a synthetic REV-ERB agonist that produces anxiolytic effects in mice, was used to treat undifferentiated and neuronally differentiated cultured rat adult hippocampal neural stem/progenitor cells (AHPs). The expression of Rev-erbβ was upregulated during neurogenesis in cultured rat AHPs, and Rev-erbβ knockdown analysis indicated that REV-ERBβ regulates the proliferation and neurite outgrowth of cultured rat AHPs. The application of a low concentration (0.1 µM) of the REV-ERB agonist SR9009 enhanced neurite outgrowth during neurogenesis in cultured rat AHPs, whereas the addition of a high concentration (2.5 µM) of SR9009 suppressed neurite outgrowth. Further examination of the SR9009 regulatory mechanism showed that the expressions of downstream target genes of REV-ERBβ, including Ccna2 and Sez6, were modulated by SR9009. The results of this study indicated that REV-ERBβ activity in cultured rat AHPs was regulated by SR9009 in a concentration-dependent manner. Furthermore, SR9009 inhibited the growth of cultured rat AHPs through various pathways, which may provide insight into the multifunctional mechanisms of action associated with SR9009. The findings of this study may provide an improved understanding of proliferation and neuronal maturation mechanisms in cultured rat AHPs through SR9009-regulated REV-ERBβ signaling pathways.

Abstract
Diverse factors including metabolism, chromatin remodeling, and mitotic kinetics influence development at the cellular level. These factors are well known to interact with the circadian transcriptional-translational feedback loop (TTFL) after its emergence. What is only recently becoming clear, however, is how metabolism, mitosis, and epigenetics may become organized in a coordinated cyclical precursor signaling module in pluripotent cells prior to the onset of TTFL cycling. We propose that both the precursor module and the TTFL module constrain cellular identity when they are active during development, and that the emergence of these modules themselves is a key lineage marker. Here we review the component pathways underlying these ideas; how proliferation, specification, and differentiation decisions in both developmental and adult stem cell populations are or are not regulated by the classical TTFL; and emerging evidence that we propose implies a primordial clock that precedes the classical TTFL and influences early developmental decisions.

Abstract
Mesial Temporal Lobe Epilepsy (mTLE) characterized by progressive development of complex partial seizures originating from the hippocampus is the most prevalent and refractory type of epilepsy. One of the remarkable features of mTLE is the rhythmic pattern of occurrence of spontaneous seizures, implying a dependence on the endogenous clock system for seizure threshold. Conversely, circadian rhythms are affected by epilepsy too. Comprehending how the circadian system and seizures interact with each other is essential for understanding the pathophysiology of epilepsy as well as for developing innovative therapies that are efficacious for better seizure control. In this review, we confer how the temporal dysregulation of the circadian clock in the hippocampus combined with multiple uncoupled oscillators could lead to periodic seizure occurrences and comorbidities. Unraveling these associations with additional research would help in developing chronotherapy for mTLE, based on the chronobiology of spontaneous seizures. Notably, differential dosing of antiepileptic drugs over the circadian period and/or strategies that resynchronize biological rhythms may substantially improve the management of seizures in mTLE patients.
