Mananoligossacarídeos em dietas para frangos de corte Mannanoligosaccharides in diets for broilers

Ciência Rural, 2011
Objetivou-se avaliar dietas contendo mananoligossacarídeos (MOS) como aditivo alternativo aos promotores de crescimento por meio do estudo da morfometria do intestino e do desempenho de frangos de corte.

Telomerase as a Growth-Promoting Factor [PDF]

Cell Cycle, 2003
Beyond its role in telomere maintenance, telomerase provides additional functions in tumorigenesis, DNA repair, and cell survival. Telomerase protects cells from apoptosis and necrosis, and stimulates growth in adverse conditions. Furthermore, gross overexpression of the catalytic subunit of telomerase (hTERT) may act as a hyperproliferative signal to ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

CD95 promotes tumour growth [PDF]

Nature, 2010
CD95 (also called Fas and APO-1) is a prototypical death receptor that regulates tissue homeostasis mainly in the immune system through the induction of apoptosis. During cancer progression CD95 is frequently downregulated or cells are rendered apoptosis resistant, raising the possibility that loss of CD95 is part of a mechanism for tumour evasion ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

GROWTH-PROMOTING FUNCTION OF LEUCOCYTES [PDF]

Journal of Experimental Medicine, 1922
Two main facts were brought to light by the preceding experiments: first, the presence of growth-activating substances in the leucocytes; second, the setting free of these substances in tissues and fluids where leucocytes accumulate. The existence of growth-promoting substances within the body of the leucocytes was to be expected.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
