Abstract Auger electron spectroscopy and ion sputtering depth profiling have been used to study Ti thin film oxidation and Ti–O 2 co-adsorption processes. The equilibrium oxide stoichiometry depends not only on the substrate temperature and interface effects, but also on the way the oxygen is incorporated. Heating the sample, either when the room temperature saturation has been achieved (post-oxidation), or from the beginning of the process, produces additional oxidation as compared to the room temperature ...

Significance There is growing evidence that preexisting autoantibodies neutralizing type I interferons (IFNs) are strong determinants of life-threatening COVID-19 pneumonia. It is important to estimate their quantitative impact on COVID-19 mortality upon SARS-CoV-2 infection, by age and sex, as both the prevalence of these autoantibodies and the risk of COVID-19 death increase with age and are higher in men. Using an unvaccinated sample of 1,261 deceased patients and 34,159 individuals from the general ...

Neuro-endocrine prostate cancer (NEPC) accounts for about 20% of lethal metastatic castration-resistant prostate cancer (CRPC). NEPC has the most aggressive biologic behavior of all prostate cancers and is associated with poor patient outcome. Effective treatment for NEPC is not available because NEPC exhibit distinct cell-surface expression profiles compared to other types of prostate cancer. Recently, the carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5) (known as CEA or CD66e) was ...

Iron is an indispensable micronutrient for all eukaryotic organisms due to its participation as a redox cofactor in many metabolic pathways. Iron imbalance leads to the most frequent human nutritional deficiency in the world. Adaptation to iron limitation requires a global reorganization of the cellular metabolism directed to prioritize iron utilization for essential processes. In response to iron scarcity, the conserved Saccharomyces cerevisiae mRNA-binding protein Cth2, which belongs to the tristetraprolin ...

Iron (Fe) is an essential element for all eukaryotic organisms because it functions as a cofactor in a wide range of biochemical processes. Cells have developed sophisticated mechanisms to tightly control Fe utilization in response to alterations in cellular demands and bioavailability. In response to Fe deficiency, the yeast Saccharomyces cerevisiae activates transcription of the CTH1 and CTH2 genes, which encode proteins that bind to AU-rich elements (AREs) within the 3' untranslated regions (3'UTRs) ...

The yeast Cth2 protein is a CX8CX5CX3H tandem zinc finger protein that binds AU-rich element (ARE)-containing transcripts to enhance their decay in response to iron (Fe) deficiency. Mammalian members of this family of proteins are known to undergo nucleocytoplasmic shuttling, but little is known about the role of shuttling in the mechanism of ARE-dependent mRNA decay. Here we demonstrate that, like its mammalian homologues, Cth2 is a nucleocytoplasmic shuttling protein whose nuclear export depends ...

SUMMARY Vacuolar H+-ATPase (V-ATPase) is a fundamentally important enzyme in eukaryotic cells that is responsible for acidification of endocytic compartments. The B subunits of V-ATPases from mammals and tobacco hornworm have been shown to bind actin filaments. Actin-binding activity by the B subunit is required for targeting V-ATPases to the plasma membrane of osteoclasts. Bacterially expressed B subunit from the yeast Saccharomyces cerevisiae bound actin filaments with a Kd of 195 nmol l–1. The ...

We have previously demonstrated in yeast that Cth2 is expressed during Fe deficiency and promotes degradation of a battery of mRNAs leading to reprogramming of Fe-dependent metabolism and Fe storage. We report here that the Cth2-homologous protein Cth1 is transiently expressed during Fe deprivation and participates in the response to Fe deficiency through the degradation of mRNAs primarily involved in mitochondrially localized ...

Iron is an essential nutrient that participates as a redox co-factor in a broad range of cellular processes. In response to iron deficiency, the budding yeast Saccharomyces cerevisiae induces the expression of the Cth1 and Cth2 mRNA-binding proteins to promote a genome-wide remodeling of cellular metabolism that contributes to the optimal utilization of iron.

Vacuolar H + -ATPases (V-ATPases) are highly conserved proton pumps that couple hydrolysis of cytosolic ATP to proton transport out of the cytosol. Although it is generally believed that V-ATPases transport protons by a rotary catalytic mechanism analogous to that used by F 1 F 0 -ATPases, the structure and subunit composition of the central or peripheral stalk of the multisubunit complex are not well understood.

SARS-CoV-2 spike harbors glycans which function as ligands for lectins. Therefore, it should be possible to exploit lectins to target SARS-CoV-2 and inhibit cellular entry by binding glycans on the spike protein. Burkholderia oklahomensis agglutinin (BOA) is an antiviral lectin that interacts with viral glycoproteins via N-linked high mannose glycans.
