Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Steady-state size distribution of air bubbles in polar ice

Лëд и снег, 2015
Between the close-off depth and the bubble-to-hydrate transition zone in polar ice sheets, the geometrical properties of air bubbles, such as number concentration and size of bubbles, are mainly controlled by firn temperature and ice accumulation rate ...

An Arctic-Tibetan Connection on Subseasonal to Seasonal Time Scale [PDF]

, 2019
Recent research indicates the great potentials of springtime land surface temperature (LST) as a new source of predictability to improve the subseasonal to seasonal climate prediction.

Environmental safety as an element of single-industry towns’ sustainable development in the Arctic region

IOP Conference Series: Earth and Environment, 2018
Maintaining a certain level of environmental safety is one of the most important goals in exploring the Arctic region, taking into account its intensified industrial development.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Attitudes toward the theory of evolution and its misconceptions in Tromsø, Northern Norway

Evolution: Education and Outreach
Background Evolution is the core of modern biology, but various misconceptions are persistent companions to the theory. The intuitively appealing but discredited suggestion that organisms innately tend to evolve in a predefined direction still lingers ...

Arctic air pollution: Challenges and opportunities for the next decade [PDF]

, 2016
The Arctic is a sentinel of global change. This region is influenced by multiple physical and socio-economic drivers and feedbacks, impacting both the natural and human environment.

Borehole temperature reconstructions reveal differences in past surface temperature trends for the permafrost in the Laptev Sea region, Russian Arctic [PDF]

, 2018
In central Siberia, past temperature changes have been driving permafrost warming in a region with large organic carbon reserves stored in the perennially frozen ground.

Modelling past, present and future peatland carbon accumulation across the pan-Arctic region

, 2017
. Most northern peatlands developed during the Holocene, sequestering large amounts of carbon in terrestrial ecosystems. However, recent syntheses have highlighted the gaps in our understanding of peatland carbon accumulation.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
