- Background: Clinicopathologic stage is still the main parameter to evaluate the prognosis of newly diagnosed colorectal cancer (CRC) patients. Although molecular markers have been suggested for follow up of treated CRC patients, their complete clinical application is still under evaluation. Materials and methods: To evaluate the association of immune-related genes with CRC prognosis and survival, a total of 19 single nucleotide polymorphisms (SNPs) were genotyped in 614 German patients within the Kiel cohort (POPGEN). Results: A promoter variant (rs1800872) in the Interleukin-10 (IL-10) gene was associated with an increased lymph node metastasis involvement [odds ratio (OR) = 2.1, 95% confidence interval (CI) = 1.03-4.2, for carriers of the TT genotype]. More importantly, among 582 followed up patients the SNP rs3775291 in the toll-like receptor 3 (TLR-3) gene was associated with CRC specific survival (150 events). Patients carrying the TT genotype had a 93% increased risk of death compared with the CC carriers [hazard ratio (HR) = 1.93, 95% CI 1.14-3.281. The observed effect of the TLR-3 variant was restricted to stage II patients (HR = 4.14, 95% CI 1.24-13.84) and to patients who did not receive adjuvant therapy (HR = 3.2, 95% CI 1.4-7.7). Conclusions: Our results may provide additional candidates for risk assessment in stage II CRC patients for treatment decision. Further validation of the presented findings is warranted.

- A variety of organisms including mammals have evolved a 24h, self-sustained timekeeping machinery known as the circadian clock (biological clock), which enables to anticipate, respond, and adapt to environmental influences such as the daily light and dark cycles. Proper functioning of the clock plays a pivotal role in the temporal regulation of a wide range of cellular, physiological, and behavioural processes. The disruption of circadian rhythms was found to be associated with the onset and progression of several pathologies including sleep and mental disorders, cancer, and neurodegeneration. Thus, the role of the circadian clock in health and disease, and its clinical applications, have gained increasing attention, but the exact mechanisms underlying temporal regulation require further work and the integration of evidence from different research fields. In this review, we address the current knowledge regarding the functioning of molecular circuits as generators of circadian rhythms and the essential role of circadian synchrony in a healthy organism. In particular, we discuss the role of circadian regulation in the context of behaviour and cognitive functioning, delineating how the loss of this tight interplay is linked to pathological development with a focus on mental disorders and neurodegeneration. We further describe emerging new aspects on the link between the circadian clock and physical exercise-induced cognitive functioning, and its current usage as circadian activator with a positive impact in delaying the progression of certain pathologies including neurodegeneration and brain-related disorders. Finally, we discuss recent epidemiological evidence pointing to an important role of the circadian clock in mental health.
