Toward a molecular understanding of yeast silent chromatin : roles for H4K16 acetylation and the Sir3 C-terminus [PDF]

, 2012
Discrete regions of the eukaryotic genome assume a heritable chromatin structure that is refractory to gene expression. In budding yeast, silent chromatin is characterized by the loading of the Silent Information Regulatory (Sir) proteins (Sir2, Sir3 and

Neddylation Targets and Stabilizes NLRP3 to Augment Inflammasome‐Mediated Colitis and Mood Disorder

Advanced Science, EarlyView.
NLRP3 inflammasome contributes to colitis and mood disorder. This study demonstrates that neddylation targets NLRP3 at K287, which hinders its interaction with K48‐linked ubiquitination E3 Trim31 and thereby stabilizes it. Neddylation blockade in myeloid cells and microglia mitigates DSS‐induced colitis and psychological stress‐induced anxiety‐like ...

Induction and Repression of the Histidine-degrading Enzymes of Bacillus subtilis

Journal of Biological Chemistry, 1968
Abstract In Bacillus subtilis a series of four enzymes is responsible for the degradation of l-histidine to ammonia, formamide, and l-glutamic acid. The third enzyme of the series was not investigated; the other three enzymes, histidase, urocanase, and formiminoglutamate hydrolase, are induced by l-histidine and repressed by catabolites. Mutants can be

Computational modeling to elucidate molecular mechanisms of epigenetic memory

, 2015
How do mammalian cells that share the same genome exist in notably distinct phenotypes, exhibiting differences in morphology, gene expression patterns, and epigenetic chromatin statuses?

A Unique Chimeric RNA: ERCC1‐iASPP Drives Benzo[a]pyrene‐Induced Lung Carcinogenesis via Dual Coding and Non‐Coding Mechanisms

Advanced Science, EarlyView.
The chimeric RNA ERCC1‐iASPP possesses dual coding and non‐coding functions, synergistically accelerating the process of cellular malignant transformation. Abstract Genetic variation at 19q13.3 critically modulates chemical carcinogen‐induced lung carcinogenesis, particularly in mediating the activity of benzo[a]pyrene (B[a]P), a major polycyclic ...

Regulating PCCA gene expression by modulation of pseudoexon splicing patterns to rescue enzyme activity in propionic acidemia

Molecular Therapy: Nucleic Acids
Pseudoexons are nonfunctional intronic sequences that can be activated by deep-intronic sequence variation. Activation increases pseudoexon inclusion in mRNA and interferes with normal gene expression.

AMP-activated protein kinase activation reduces the transcriptional activity of the murine luteinizing hormone β-subunit gene

The Journal of Reproduction and Development, 2019
Malnutrition is one of the factors that induces reproductive disorders. However, the underlying biological processes are unclear. AMP-activated protein kinase (AMPK) is an enzyme that plays crucial role as a cellular energy sensor.

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,
