Circadian disruption is pervasive and can occur at multiple organizational levels, contributing to poor health outcomes individual population levels. Evidence points a bidirectional relationship, in that circadian increases disease severity many diseases disrupt rhythms. Importantly, increase the risk for expression development of neurologic, psychiatric, cardiometabolic, immune disorders. Thus, harnessing rich findings from preclinical translational research biology enhance via circadian-based approaches represents unique opportunity personalized/precision medicine overall societal well-being. In this Review, we discuss implications human using bench-to-bedside approach. science applied clinical population-based Given broad regulation health, Review focuses its discussion on selected examples metabolic, cardiovascular, allergic, immunologic disorders highlight interrelatedness between potential interventions, such as bright light therapy exogenous melatonin, well chronotherapy improve and/or modify outcomes.

Molecular regulations of circadian rhythm and implications for physiology and diseases

Signal Transduction and Targeted Therapy, Journal Year: 2022, Volume and Issue: 7(1)

Published: Feb. 8, 2022

The term "circadian rhythms" describes endogenous oscillations with ca. 24-h period associated the earth's daily rotation and light/dark cycle. Such rhythms reflect existence of an intrinsic circadian clock that temporally orchestrates physiological processes to adapt internal environment external cues. At molecular level, consists multiple sets transcription factors resulting in autoregulatory transcription-translation feedback loops. Notably, addition their primary role as generator rhythm, biological plays a key controlling functions almost all tissues organs. It regulates several intracellular signaling pathways, ranging from cell proliferation, DNA damage repair response, angiogenesis, metabolic redox homeostasis, inflammatory immune response. In this review, we summarize findings showing crosstalk between some describing scenario wherein reciprocal regulation impinges upon aspects mammalian physiology. Moreover, based on evidence indicating can be challenged by environmental factors, social behaviors, well pre-existing pathological conditions, discuss implications misalignment human pathologies, such cancer diseases. Accordingly, disruption rhythm has been reported affect are relevant Expanding our understanding field represents intriguing transversal medicine challenge order establish precision medicine.

Circadian Expression of Migratory Factors Establishes Lineage-Specific Signatures that Guide the Homing of Leukocyte Subsets to Tissues

Immunity, Journal Year: 2018, Volume and Issue: 49(6), P. 1175 - 1190.e7

Published: Dec. 1, 2018

The number of leukocytes present in circulation varies throughout the day, reflecting bone marrow output and emigration from blood into tissues. Using an organism-wide circadian screening approach, we detected oscillations pro-migratory factors that were distinct for specific vascular beds individual leukocyte subsets. This rhythmic molecular signature governed time-of-day-dependent homing behavior subsets to organs. Ablation BMAL1, a transcription factor central clock function, endothelial cells or demonstrated recruitment is dependent on both microenvironmental cell-autonomous oscillations. These oscillatory patterns defined trafficking homeostasis inflammation determined detectable tumor burden cancer models.

Circadian clock component REV-ERBα controls homeostatic regulation of pulmonary inflammation

Journal of Clinical Investigation, Journal Year: 2018, Volume and Issue: 128(6), P. 2281 - 2296

Recent studies reveal that airway epithelial cells are critical pulmonary circadian pacemaker cells, mediating rhythmic inflammatory responses. Using mouse models, we now identify the repressor REV-ERBα as essential to mechanism coupling clock innate immunity, involving both myeloid and bronchial in temporal gating determining amplitude of response inhaled endotoxin. Dual mutation its paralog REV-ERBβ epithelia further augmented responses chemokine activation, but also initiated a basal state, revealing homeostatic role for REV-ERB proteins suppression endogenous proinflammatory unchallenged cells. However, plays dominant role, deletion alone had no impact on In turn, challenges cause striking changes stability degradation protein, driven by SUMOylation ubiquitination.

The quality and quantity of tumor-infiltrating lymphocytes, particularly CD8+ T cells, are important parameters for the control tumor growth response to immunotherapy. Here, we show in murine human cancers that these exhibit circadian oscillations, driven by both endogenous clock leukocytes rhythmic leukocyte infiltration, which depends on endothelial cells microenvironment.
