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.

Ações coletivas civis na atualidade: dos programas de responsabilidade/compromisso social às redes de movimentos sociais

open access: yesCiências Sociais Unisinos, 2010
This paper focuses on the protagonism of the civil society by addressing the theme of the civil collective actions. Therefore, some conceptual presuppositions should be explained allowing that the subjects, and the character of these actions to be known ...

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 ...

Pour la mémoire de César

open access: yesCahiers Mondes Anciens
After Caesar’s funeral, already disrupted by popular excesses, a crowd gathered for several weeks on the Forum to honour the deceased and call for revenge against his murderers. This is one of the rare occurrences (apart from the food riots) where people

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

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.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

COLLECTIVE ACTORS CONSTRUCTION AND ORGANIZATIONAL LEADERSHIP IN REGIONAL DEVELOPMENT: THE EXEMPLE OF THE STRATÉGIE MIGRACTION IN QUEBEC

open access: yesRedes, 2014
The collective actor becomes a reality as the leadership of an organization evolves from an individual to a holistic form, thus transcending individuals forming the organization.

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

open access: yesFEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Feminist or Paternalistic: Understanding Men’s Motivations to Confront Sexism

open access: yesFrontiers in Psychology, 2020
The role of men in fighting gender inequality is a controversial issue. Literature has shown that advantaged group members can promote social change but also perpetuate status quo. We conducted three studies to examine two motivational processes that may
