Role of biological rhythms in the performance of physical activity

open access: yesJournal of Physical Fitness and Sports Medicine, 2017
Most organisms display various periodicities. Periodicity has been observed in humans in association with sleep, body temperature and hormone secretion. The molecular mechanisms involved are being elucidated by the investigation of clock genes in mammals.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Site-selective α-C(sp3)–H arylation of dialkylamines via hydrogen atom transfer catalysis-enabled radical aryl migration

open access: yesNature Communications
Site-selective C(sp3)–H arylation is an appealing strategy to synthesize complex arene structures but remains a challenge facing synthetic chemists. Here we report the use of photoredox-mediated hydrogen atom transfer (HAT) catalysis to accomplish the ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

The mechanism of parvalbumin interneurons regulating glutamatergic neurons involvement in stress induced anxiety in the basolateral amygdala of male mice

open access: yesScientific Reports
Modern life’s fast-paced and the unexpected conditions contribute to escalating stress levels, often leading to anxiety disorders and posing significant challenges to physical and mental health. In judicial practice, the parties often suffer from anxiety

An Exclusively Skewed Distribution of Pediatric Immune Reconstitution Inflammatory Syndrome Toward the Female Sex Is Associated With Advanced Acquired Immune Deficiency Syndrome

open access: yesFrontiers in Pediatrics, 2019
In human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) patients with very low CD4 cell counts, there is a temporal relationship between administration of antiretroviral therapy (ART) and an increased inflammatory response ...

Identification of new molecular biomarkers: Proteomics

open access: yesSanamed, 2018
The pathogenesis of the tumor is extremely complex and can not be fully explained by the existing methodological approaches. Proteomics is an interdisciplinary science that deals with the study of proteins, carriers of the biological functions of the organism.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
