Self-organized transition to coherent activity in disordered media [PDF]

open access: yes, 2012
Synchronized oscillations are of critical functional importance in many biological systems. We show that such oscillations can arise without centralized coordination in a disordered system of electrically coupled excitable and passive cells.

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 ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Structure-activity relationships on cynnamoyl derivatives as inhibitors of p300 Histone acetyltransferase [PDF]

open access: yes, 2017
Human p300 is a polyhedric transcriptional coactivator, playing a crucial role by acetylating histones on specific lysine residues. A great deal of evidences shows that p300 is involved in several diseases as leukemia, tumors and viral infection.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Cell biological mechanisms of activity-dependent synapse to nucleus translocation of CRTC1 in neurons. [PDF]

open access: yes, 2015
Previous studies have revealed a critical role for CREB-regulated transcriptional coactivator (CRTC1) in regulating neuronal gene expression during learning and memory. CRTC1 localizes to synapses but undergoes activity-dependent nuclear translocation to

Biological Activity of Tropolone

open access: yesBiological and Pharmaceutical Bulletin, 2003
Tropolone (1). showed strong insecticidal activity on Tyrophagus putrescentiae and Dermatophagoides farinae. The insecticidal effect of 1 on both insects was stronger than that of hinokitiol (2, 4-isopropyltropolone: major component of Thujopsis dolabrata SIEB. et ZUCC. hondai MAKINO). The insecticidal activity of both compounds was higher than that of

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

How Does Virtual Reality Training Affect Reaction Time and Eye–Hand Coordination? The Impact of Short- and Long-Term Interventions on Cognitive Functions in Amateur Esports Athletes

open access: yesApplied Sciences
This study investigates the efficacy of VR-based cognitive training using the game Beat Saber in enhancing cognitive functions in amateur e-athletes. Participants were divided into two groups, undergoing either 8-day or 28-day training.
