(Texas A&M University, 2006-08-16)Melatonin is rhythmically synthesized and released by the pineal gland and, in some species, retina during the night and regulates many physiological and behavioral processes in birds and mammals. Chick diencephalic ...
-
(2015-09-23)Circadian clocks drive rhythmic gene expression to enable biological functions to perform optimally at the most appropriate time of day. Circadian rhythms rely on the binding of the transcription factor CLOCK:BMAL1 to ...
-
(2016-05-06)Circadian regulation of Mitogen Activated Protein Kinase (MAPK) pathways provides a priming mechanism to allow organisms to anticipate daily environmental stresses such as heat, light, desiccation and osmotic stress. In ...
-
(2009-06-02)Circadian rhythms of behavior have been well characterized in organisms including mammals, plants, insects, fungi, and photosynthetic bacteria. Cyanobacteria, such as the unicellular Synechococcus elongatus PCC 7942, display ...
-
(Texas A&M University, 2005-02-17)Circadian rhythms are visible as daily oscillations in biochemical, physiological, or behavioral processes. These rhythms are produced by an endogenous clock that maintains synchrony with the external environment through ...
-
(Texas A&M University, 2006-10-30)The circadian input kinase gene (cikA) was first identified from a Tn5 mutant of Synechococcus elongatus PCC 7942. A cikA null strain shows a striking phenotype related to circadian gene regulation: all sampled loci show ...
-
(Texas A&M University, 2006-04-12)The genetic identification of molecular mechanisms responsible for circadian rhythm generation has advanced tremendously over the past 25 years. However the molecular identities of the avian clock remain largely unexplored. ...
-
(2015-08-09)Metformin, as one of the first-line clinical anti-diabetic oral drugs for T2DM, has been shown to have beneficial effects including decreasing hepatic glucose production (HGP), improving insulin sensitivity, and suppressing ...
-
(2021-11-23)Roughly half of eukaryotic mRNAs cycle in abundance under control of the circadian clock, with some mRNAs peaking in levels during the day, and other mRNAs peaking in levels during the night. While phase regulation is ...
-
(2019-04-23)The circadian clock regulates the rhythmic expression of roughly half of the eukaryotic genome at the level of mRNA abundance. However, little is known about how rhythmic phase is regulated (Delaunay & Laudet, 2002). ...
-
(2013-08-12)Mitogen activated protein kinase (MAPK) pathways are conserved biochemical signal transduction pathways in eukaryotic organisms. These signaling pathways demonstrate great versatility in their ability to detect various ...
-
(2009-05-15)Avian circadian clocks are composed of a distributed network of neural and peripheral oscillators. Three neural pacemakers, located in the pineal, the eyes, and the hypothalamus, control circadian rhythms of many biological ...
-
(2021-04-22)The circadian clock is a conserved endogenous time keeping mechanism that controls up to half of the eukaryotic genome at the level of transcript abundance. In addition to clock control of transcript abundance, our lab ...
-
(2009-05-15)The study of the in vitro circadian oscillator of the cyanobacterium Synechococcus elongatus has uncovered a complex interplay of its three protein components. Synchronization of the clock's central oscillatory component, ...
-
(Texas A&M University, 2007-04-25)The avian circadian system is composed of multiple inputs, oscillators and outputs. Among its oscillators is a hypothalamic structure presumed to be homologous to the primary circadian pacemaker in mammals, the suprachiasmatic ...
-
(2016-04-08)The presence of circadian rhythms during early development has been poorly examined until very recently in vertebrate species. Previous studies have focused on the development of specific structures involved in the control ...
-
Roughly half of the eukaryotic genome is under the control of a circadian clock at the level of transcript abundance, with rhythmic transcripts peaking at all possible phases of the day. However, the mechanism for phase ...
