Circadian rhythms and cancers: the intrinsic links and therapeutic potentials

Journal of Hematology & Oncology, Journal Year: 2022, Volume and Issue: 15(1)

Published: March 4, 2022

The circadian rhythm is an evolutionarily conserved time-keeping system that comprises a wide variety of processes including sleep-wake cycles, eating-fasting and activity-rest coordinating the behavior physiology all organs for whole-body homeostasis. Acute disruption may lead to transient discomfort, whereas long-term irregular will result in dysfunction organism, therefore increasing risks numerous diseases especially cancers. Indeed, both epidemiological experimental evidence has demonstrated intrinsic link between dysregulated cancer. Accordingly, rapidly understanding molecular mechanisms rhythms opening new options cancer therapy, possibly by modulating clock. In this review, we first describe general regulators their functions on addition, provide insights into underlying how several types (including sleep-wake, eating-fasting, activity-rest) can drive progression, which expand our development from clock perspective. Moreover, also summarize potential applications treatment, optional therapeutic strategy patients.

Wearable technology and systems modeling for personalized chronotherapy

Current Opinion in Systems Biology, Journal Year: 2020, Volume and Issue: 21, P. 9 - 15

Published: June 1, 2020

Chronotherapy is a pharmaceutical intervention that considers the patient's internal circadian time to adjust dosing time. Although it can dramatically improve drug efficacy and reduce toxicity, large variability in across within individuals has prevented chronotherapies from progressing beyond clinical trials. To translate chronotherapy developments into real-world outpatient scenario, personalized characterization analysis of essential. Here, we describe recent advances wearable technology enable real-time high-resolution tracking ultradian rhythms. We discuss how integrating data platforms including systems modeling machine learning pave way toward adaptive chronotherapy.

Scheduling anticancer drug administration over 24 h may critically impact treatment success in a patient-specific manner. Here, we address personalization of timing using novel mathematical model irinotecan cellular pharmacokinetics and –dynamics linked to representation the core clock predict toxicity colorectal cancer (CRC) model. The is fitted three different scenarios: mouse liver, where metabolism mainly occurs, two human cell lines representing an vitro experimental system for progression. Our successfully recapitulates quantitative circadian datasets mRNA protein expression together with timing-dependent cytotoxicity data. also discriminates time-dependent between cells, suggesting that can be optimized according their clock. results show degradation mediating activation, as well oscillation death rate play important role variations toxicity. In future, this used support personalized scheduling by predicting optimal based on patient's gene profile.

Modeling the Circadian Control of the Cell Cycle and Its Consequences for Cancer Chronotherapy

Biology, Journal Year: 2023, Volume and Issue: 12(4), P. 612 - 612

Published: April 18, 2023

The mammalian cell cycle is governed by a network of cyclin/Cdk complexes which signal the progression into successive phases division cycle. Once coupled to circadian clock, this produces oscillations with 24 h period such that each phase synchronized day-night Here, we use computational model for clock control investigate entrainment in population cells characterized some variability kinetic parameters. Our numerical simulations showed successful and synchronization are only possible sufficient amplitude an autonomous close h. Cellular heterogeneity, however, introduces cells. Many cancer have disrupted or compromised control. In these conditions, runs independently leading lack When coupling weak, largely impacted, but maintain tendency divide at specific times day. These differential features between healthy can be exploited optimize timing anti-cancer drug administration order minimize their toxicity maximize efficacy. We then used our simulate chronotherapeutic treatments predict optimal drugs targeting Although qualitative, highlights need better characterize cellular heterogeneity populations as well consequences design chronopharmacological protocols.

Circadian regulation of sinoatrial nodal cell pacemaking function: Dissecting the roles of autonomic control, body temperature, and local circadian rhythmicity

PLoS Computational Biology, Journal Year: 2024, Volume and Issue: 20(2), P. e1011907 - e1011907

Published: Feb. 26, 2024

Strong circadian (~24h) rhythms in heart rate (HR) are critical for flexible regulation of cardiac pacemaking function throughout the day. While this flexibility HR is sustained diverse conditions, it declines with age, accompanied by reduced maximal performance. The intricate involves orchestration autonomic nervous system (ANS), body temperature (CRBT), and local rhythmicity (LCR), which has not been fully understood. Here, we developed a mathematical model describing ANS, CRBT, LCR sinoatrial nodal cells (SANC) that accurately captures distinct patterns adult aged mice. Our underscores how alliance among achieves to cover wide range firing rates SANC, performance achieve rates, while preserving robustness generate rhythmic irrespective external conditions. Specifically, ANS dominates promoting SANC performance, CRBT act as primary secondary boosters, respectively, further enhance Disruption age results impaired but robustness. This unexpected outcome primarily attributed age-related reduction parasympathetic activities, maintains compromising flexibility. work sheds light on regulating time-of-day dysfunction, offering insights into novel therapeutic targets prevention treatment arrhythmias.

Published: Feb. 29, 2024

The growing numbers of cancer cases represent a medical and societal burden worldwide. More than half all patients are treated with chemotherapy. Yet, chemotherapeutic drugs kill not only cells, but also healthy tissue, causing massive adverse side effects. Recent research on circadian medicine suggests that side-effects can be reduced, treatment efficacy increased, by considering the biological clock patients. Integrating profiles molecular markers in personalized mathematical models simulate individual dynamics drug uptake, action cellular response to This requires advanced computational tools balance prediction quality overfitting. Personalized will eventually lead an optimal alignment timing inner patient, reducing effects, increasing enhancing patient well-being.
