Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

A new multi-gas constrained model of trace gas non-homogeneous transport in firn: evaluation and behaviour at eleven polar sites [PDF]

, 2012
Insoluble trace gases are trapped in polar ice at the firn-ice transition, at approximately 50 to 100 m below the surface, depending primarily on the site temperature and snow accumulation.

Isotopic turnover in polar cod (Boreogadus saida) muscle determined through a controlled feeding experiment

Journal of Fish Biology, 2023
AbstractPolar cod (Boreogadus saida) is an important trophic link within Arctic marine food webs and is likely to experience diet shifts in response to climate change. One important tool for assessing organism diet is bulk stable isotope analysis. However, key parameters necessary for interpreting the temporal context of stable isotope values are ...

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

FEBS 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 ...

A preliminary study on the treatment of restaurant wastewater using electrocoagulation technique

Journal of Degraded and Mining Lands Management, 2020
Restaurant Wastewater (RW) is characterized by high volume and strength, with minimal treatment before its release into the environment. Electrocoagulation (EC) could be a better alternative due to its environmental friendliness.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

The thick-billed murre (Uria lomvia) in Northwest Greenland (Avanersuaq) relies on Arctic cod (Boreogadus saida) in a changing climate

Arctic Science
Considering seabirds as indicators of environmental change, we compared thick-billed murre (Uria lomvia (Linnaeus, 1758)) adult and chick diet in the North Water polynya region, NW Greenland, during 1997 and 2023.

Toward autonomous surface-based infrared remote sensing of polar clouds: retrievals of cloud optical and microphysical properties [PDF]

Atmospheric Measurement Techniques, 2019
Improvements to climate model results in polar regions require improved knowledge of cloud properties. Surface-based infrared (IR) radiance spectrometers have been used to retrieve cloud properties in polar regions, but measurements are sparse ...

Historical Arctic Logbooks Provide Insights into Past Diets and Climatic Responses of Cod [PDF]

, 2015
Gadus morhua (Atlantic cod) stocks in the Barents Sea are currently at levels not seen since the 1950s. Causes for the population increase last century, and understanding of whether such large numbers will be maintained in the future, are unclear.
