It is the best journal to keep up to date with endocrine pathophysiology both in the clinical and in the research field. It publishes the best original articles of large research institutions, as well as prestigious reviews. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years.

The circadian transcriptional repressors cryptochrome 1 Cry1 and 2 Cry2 evolved from photolyases, bacterial light-activated DNA repair enzymes. We demonstrate that genotoxic stress stimulates Cry1 phosphorylation and its deubiquitination by Herpes virus associated ubiquitin-specific protease Hausp, a. These results suggest that Cry1 and Cry2, which evolved from DNA repair enzymes, protect genomic integrity via coordinated transcriptional regulation. Many aspects of our physiology and behavior, most notably our patterns of sleep and wakefulness, are synchronized with the day—night cycle. These circadian rhythms are generated and maintained by the circadian clock, which consists of positive and negative feedback loops formed by a large number of genes and proteins.

Post-transcriptional control of the mammalian circadian clock: implications for health and disease

Rhythmic changes are controlled by an endogenous time keeper, the circadian clock, and include sleep-wake cycles, physical and mental performance capability, blood pressure, and body temperature. Consequently, many diseases, such as metabolic, sleep, autoimmune and mental disorders and cancer, are connected to the circadian rhythm. The development of therapies that take circadian biology into account is thus a promising strategy to improve treatments of diverse disorders, ranging from allergic syndromes to cancer. Circadian alteration of body functions and behavior are, at the molecular level, controlled and mediated by widespread changes in gene expression that happen in anticipation of predictably changing requirements during the day. At the core of the molecular clockwork is a well-studied transcription-translation negative feedback loop.

Utilizing antiserum which crossreacted minimally even with the monoglucosiduronate metabolites, unextracted plasma estriol measurements were identical statistically to ether extract determinations.

Samer R. Franco, Bruno H. Stricker, Robin P. In vitro and in vivo experiments have assigned both oncosuppressive and oncogenic properties to thyroid hormones. Population-based studies have found inconclusive results. We aimed to prospectively assess the relation between thyroid function and incident cancer in a population-based setting.

DNA damage itself can reset the clock. Cellular metabolism is altered in cancer. Several key metabolic genes are under circadian regulation. Recent findings that​.


Cancer Clocks Out for Lunch: Disruption of Circadian Rhythm and Metabolic Oscillation in Cancer

Systems Biology and the challenge of deciphering the metabolic mechanisms underlying cancer View all 11 Articles. Circadian rhythms are h oscillations present in most eukaryotes and many prokaryotes that synchronize activity to the day-night cycle. They are an essential feature of organismal and cell physiology that coordinate many of the metabolic, biosynthetic, and signal transduction pathways studied in biology.

DNA damage shifts circadian clock time via Hausp-dependent Cry1 stabilization

Author contributions: R. The circadian rhythm of glucocorticoids affects diverse physiological systems, including stress responses and the coordination of rhythmic functions in peripheral and central tissues. Circadian clocks are considered to be important coordinators of glucocorticoid release and loss of the core clock component Brain and muscle Arnt-like protein-1 leads to ablation of behavioral and physiological rhythms, hypocortisolism, impaired ACTH, and behavioral stress responses. Transplantation and conditional clock gene knock-down studies in mice suggest an important role of local adrenocortical clock function in this context. Here, we present a Cre-loxP -mediated conditional knockout of Bmal1 in the steroidogenic cells of the adrenal cortex in mice.

Melatonin is a hormone primarily released by the pineal gland at night, and has long been associated with control of the sleep—wake cycle. Side effects from melatonin supplements are minimal at low doses for short durations. In vertebrates, melatonin is involved in synchronizing circadian rhythms , including sleep—wake timing and blood pressure regulation, and in control of seasonal rhythmicity including reproduction, fattening, moulting and hibernation. Melatonin was discovered in

 При всем моем уважении к вам, сэр, - сказала Мидж, - я бы порекомендовала послать в шифровалку бригаду службы безопасности - просто чтобы убедиться… - Ничего подобного мы делать не будем. На этом Мидж капитулировала: - Хорошо. Доброй ночи.  - Она двинулась к двери. Когда Мидж проходила мимо, Бринкерхофф по выражению ее глаз понял, что она и не думает сдаваться: чутье не позволит ей бездействовать.

Он снова попробовал ее позвать, но язык отказывался ему подчиняться. Девушка почти уже добралась до двери. Беккер поднялся на ноги, пытаясь выровнять дыхание. Попробовал добрести до двери. Меган скрылась во вращающейся секции, таща за собой сумку. Беккер почти вслепую приближался к двери.

Он профессор лингвистики, а не физики. - Атакующие линии готовятся к подтверждению доступа. - Господи! - Джабба в отчаянии промычал нечто нечленораздельное.

 Спальня, - без колебаний отозвался. Сьюзан смутилась. - Хорошо, а что, если… кошка. - Жила! - не задумываясь выпалил Беккер. - Жила.

 - Все становится на свои места. Какой-то миг еще ощущались сомнения, казалось, что в любую секунду все снова начнет разваливаться на части.
