Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

A escolha do Estado social

open access: yes, 2008
O autor faz uma abordagem hipotético-dedutiva dos pressupostos iniciais e das principais articulações lógicas do regime de pensamento no qual o Estado é levado a executar um papel essencial na regulação dos disfuncionamentos sociais. Como promotor da coesão social, o Estado procura prevenir os riscos da dissociação social, estabelecendo regulações ...

Direitos Sociais: do Estado Liberal ao Estado Social

open access: yesPrim@ Facie, 2017
A partir de pesquisa conceitual e teórico normativa, este texto objetiva demonstrar a trajetória dos direitos sociais, desde as condições históricas que antecedem seu reconhecimento, mas se referem aos fatos que lhes dão origem; passando pelos caminhos que se vinculam diretamente ao seu surgimento e às instituições que fornecem sustentáculo a este, até

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

open access: yesFEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Estado, sociedade civil e serviço social

open access: yes, 2003
O texto divide-se em duas partes: a.) numa primeira parte tento proceder à fundamentação teórica do Estado Social; b) numa segunda parte procuro demonstrar que a política não se reduz a uma actividade abstracta que se realiza apenas no plano colectivo e desconhece a realidade concreta das comunidades e até dos corpos.
