Teleost‐specific ictacalcins exhibit similar structural organization, cation‐dependent activation, and transcriptional regulation as human S100 proteins

The FEBS Journal, EarlyView.
Calcium‐binding S100 proteins are important mediators of inflammation in humans. Distant members of this family have been recently discovered in teleost fish but their resemblance to human proteins has not been explored yet. This study demonstrates that zebrafish‐specific S100i1 and S100i2 (ictacalcins) possess identical structural organization and ...

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Redox environment modulates aggregation of ataxin‐3 in vitro — Implications for drug screening of cysteine‐rich proteins

The FEBS Journal, EarlyView.
Redox environment modulates in vitro aggregation of Ataxin‐3, the protein implicated in spinocerebellar ataxia type 3. Reducing conditions stabilize native monomers and prevent aggregation, whereas oxidative conditions promote the formation of non‐native conformers and disulfide‐linked oligomers within the Josephin domain (JD).

Un nuevo género para Habrothrix angustidens y Akodon serrensis (RODENTIA, CRICETIDAE): de nuevo palentología y neontología se encuentran en el legado de Lund [PDF]

, 2016
We describe a new genus of sigmodontine rodent to allocate a fossil species from Lagoa Santa cave deposits, Habrothrix angustidens Winge, and a living species from southeastern Atlantic Forest described at the start of the past century, Akodon serrensis ...

Biologia molecular dos tumores do trato digestivo

Clinical and Biomedical Research, 2017
Uma revolução no entendimento da gênese do câncer humano vem acontecendo, e sua natureza fundamentalmente genética foi reconhecida. Os cânceres gastrointestinais apresentam alta incidência e prognóstico reservado na maioria dos casos quando da sua apresentação em nosso meio.

TNF‑α Gene Polymorphisms as Determinants of Alloantibody Emergence in Hemophilia: A Systematic Review and Meta‐Analysis

Haemophilia, EarlyView.
ABSTRACT Introduction Inhibitor development remains one of the most serious complications of replacement therapy in patients with hemophilia. Tumour necrosis factor‐alpha (TNF‐α) is a key pro‐inflammatory cytokine, and its genetic variants have been implicated in immune‐related conditions.

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, EarlyView.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Multiple Periapical Lesions Influence the Expression of TLR4/NF‐κB Pathway Components and the Development of Hepatic Injuries in Healthy and Chronic Alcohol‐Consuming Rats

International Endodontic Journal, EarlyView.
ABSTRACT Aim To evaluate the impact of multiple apical periodontitis (AP) on the expression of TLR4/NF‐κB pathway components, proinflammatory cytokine levels, and development of hepatic injuries in rats with and without chronic alcohol consumption. Methodology Thirty‐two rats were assigned to four groups (n = 8): Control, AP, Alcohol, and Alcohol+AP ...
