Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

How phagocytic cells kill bacteria: Lessons from a professional killer

FEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

FEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Gelatinization with formic acid

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1979
1. A study has been made of the gelatins obtained by treating a number of fresh and fossil collagens with dilute formic acid. 2. Compositions of their peptides separated by filtration through polyacrylamide gels has been established. 3. Solubilization results in the freeing of much aspartic acid and less glycine, the amounts being determined for the ...

Electrochemical CO2 reduction to formic acid on a Pd-based formic acid oxidation catalyst

Catalysis Today, 2015
The electrochemical reduction of CO2 is a reaction of much current interest as a possible reaction for energy storage. In this paper, we show that on electrodeposited palladium on platinum, a good formic acid oxidation catalyst, the onset potential for ...

FORMIC ACID OR FORMIC ACID–FORMALIN AS A SILAGE ADDITIVE

Canadian Journal of Animal Science, 1973
Three methods of ensiling an alfalfa–bromegrass mixture were compared: field-wilted (W) (45% dry matter (DM)); direct-cut (F) (24% DM) with 85% formic acid added at the harvester at 0.5% w/w; and direct-cut (FF) (25% DM) with a formic acid–formalin mixture similarly added at 0.5% w/w. The formic acid–formalin mixture was a 1:1 ratio of 85% formic acid

Dissociation constants of formic acid and formic acid-d

Transactions of the Faraday Society, 1963
It is shown by conductivity measurements that DCO/sub 2/H has a smaller dissociation constant than HCO/sub 2/H in aqueous solution. The observed difference, e (1000 to 2000 pK = 0.035 surface proces 0.002, agrees with a theoretical calculation of the secondary isotope effect. (auth)

Liquid Sunshine: Formic Acid

The Journal of Physical Chemistry Letters, 2022
"Liquid sunshine" is the conceptual green liquid fuel that is produced by a combination of solar energy, CO2, and H2O. Alcohols are commonly regarded as the preferred candidates for liquid sunshine because of their advantages of high energy density and extensive industrial applications.

Urinary Formic Acid as an Indicator of Occupational Exposure to Formic Acid and Methanol

AIHAJ, 1987
A sampling strategy was developed to detect personal exposure to methanol and formic acid vapors. Formic acid is the metabolic end product of methanol, and part of inhaled formic acid is excreted directly in urine, so that urinary formic acid would reveal exposure to both agents.
