Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

The C‐terminal region of KIF26B is indispensable for nephron progenitor condensation and kidney formation in mice

FEBS Open Bio, EarlyView.
KIF26B plays an important role in kidney development. We engineered mice lacking the C‐terminal region of KIF26B and found severe kidney defects, including bilateral renal agenesis, similar to full Kif26b knockout mice. The mutation disrupted nephron progenitor condensation and reduced Gdnf‐Wnt11 signaling, showing that the KIF26B C‐terminal region is ...

Regulated Gene Expression in Gene Therapy

Annals of the New York Academy of Sciences, 2001
Abstract: The original model of gene therapy, that of efficient delivery, durable transfer, and stable expression of transgenes to correct a gene defect underlying an inherited disease, is limited in light of improved understanding of the processes involved.

Ploidy Regulation of Gene Expression

Science, 1999
Microarray-based gene expression analysis identified genes showing ploidy-dependent expression in isogenic Saccharomyces cerevisiae strains that varied in ploidy from haploid to tetraploid. These genes were induced or repressed in proportion to the number of chromosome sets, regardless of the mating type.

Regulation of histone gene expression

Current Opinion in Cell Biology, 1992
Histone genes are expressed during the S phase of the cell cycle. Control is at multiple levels and is mediated by the integration of regulatory signals in response to cell-cycle progression and the onset of differentiation. Much work has been carried out on the H4 gene promoter, which appears to be organized into a series of distinct regulatory ...

Regulation of Gene Expression

New England Journal of Medicine, 1994
Genetics is a language with rules of composition that give the tissues of the body their special traits. These rules govern the activation of particular subgroups of genes, which determine not only the unique characteristics of a cell type but also whether it remains quiescent, divides, or dies. The timing of gene activation is very important. If genes

Regulation of gene expression

British Medical Bulletin, 1991
A fundamental tenet of biology is that the phenotype of an organism is ultimately determined by its complement of genes. In multicellular organisms, it is the regulated pattern of expression of genes which determines the proliferation and differentiation of individual cell lineages and hence establishes the adult phenotype.

Regulation of Cytokine Gene Expression

Annual Review of Immunology, 1988
Following the isolation and characterization of many cytokine genes, we began to understand the mechanisms regulating cytokine gene expression. Needless to say, understanding the mechanisms by which induction of gene expression occurs in a transient, cell type-specific manner in response to extracellular inducers is a central issue in eukaryotic ...
