Loss of proton‐sensing GPR4 reduces tumor progression in mouse models of colon cancer
G protein‐coupled receptor 4 (GPR4) is a pH‐sensing receptor activated by acidic pH. GPR4 expression is increased in patients with inflammatory bowel disease who are at high risk of developing colorectal cancer. In mouse models, loss of GPR4 attenuated tumor progression. This correlated with increased IL2 and natural killer cell activity.

The Age of the Earth and the Saltness of the Sea [PDF]
The analysis of rocks shows clearly that the proportion of sodium in the sedimentaries is much smaller than in the igneous rocks. The natural inference from this is that the balance is to be found in the ocean in the form of salt. Assuming these premises and a fairly uniform rate of erosion, the estimation of geologic time is -reduced to a process of ...

The distribution of sea-salt aerosol in the global troposphere [PDF]
Abstract. We present the first data on the concentration of sea-salt aerosol throughout most of the depth of the troposphere and over a wide range of latitudes. Sea salt concentrations in the upper troposphere are very small, usually less than 10 ng per standard m3 (about 10 parts per trillion by mass) and often less than 1 ng m−3.

Loss of primary cilia in endothelial cells promotes EndMT and vascular abnormalities in the ovarian tumor microenvironment through EphA2 activation. Using human samples, in vitro models, and endothelial‐specific Kif3a‐knockout mice, we show that primary cilia loss drives the acquisition of cancer‐associated fibroblast‐like phenotypes, thereby ...

Revising the hygroscopicity of inorganic sea salt particles [PDF]
AbstractSea spray is one of the largest natural aerosol sources and plays an important role in the Earth’s radiative budget. These particles are inherently hygroscopic, that is, they take-up moisture from the air, which affects the extent to which they interact with solar radiation.

Overexpression of CHRDL2 in colon cancer cells makes them more stem‐like and resistant to chemo‐ and radiotherapy. CHRDL2‐high cells have upregulation of the WNT pathway, genes involved in the DNA damage response (DDR) pathway and epithelial‐to‐mesenchymal transition (EMT). This leads to quicker repair of damaged DNA and more cell migration.

The Saltness and the Temperature of the Sea 1 [PDF]
PROFESSOR DITTMAR'S researches, an account of which forms Part 1. of this volume, have finally proved that, so far as the most refined analysis can go, the mixture of salts dissolved in ocean water has attained a state of chemical equilibrium. But, although there is constancy of proportion between the various salts, the ratio of the total salts to the ...

We obtained potential bacterial laccase‐like multicopper oxidase (LMCO) sequences through metagenomic sequencing. All sequences exhibited significant differences from known LMCOs in databases. To select the most promising candidates, we performed structure prediction and molecular docking using alphafold2, metal3d and rosetta.

Ca2+‐mediated response to DMSO was investigated in Saccharomyces cerevisiae cells expressing Ca2+‐dependent aequorin. Cell exposure to DMSO induced a cytosolic Ca2+ wave dependent on the integrity of the Cch1/Mid1 channel. Deletion of KCS1 or VIP1 genes encoding the phosphoinositol pyrophosphate (PP‐IP) synthases suppressed the DMSO‐induced Ca2 ...

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.
