Mechanistic Insights and Pharmacological Approaches for Nitrogen and Sulfur Mustards and Their Implications as Therapeutic Agents

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nitrogen and sulfur mustards, often acting as vesicants, have significant consequences for public health. Skin is a common site for exposure to these vesicants that can result in considerable morbidity and mortality. Given that the treatment options are limited, new insights into the mechanisms for the toxicity of these vesicants that can be ...

Multiomics Reveal Associations Between CpG Methylation, Histone Modifications and Transcription in a Species That has Lost DNMT3, the Colorado Potato Beetle

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Despite lacking DNMT3, EM‐seq revealed CpG methylation in the Colorado potato beetle. CUT&Tag analysis showed an association of H3K36me3 and H3K27ac with transcription, with H3K36me3 mirroring CpG methylation, demonstrating epigenetic flexibility.

ATAC‐seq in Emerging Model Organisms: Challenges and Strategies

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Principle of ATAC‐seq (left), overview of arthropod species with published ATAC‐seq data (middle), summary of experimental design (right). ABSTRACT The Assay for Transposase‐Accessible Chromatin with sequencing (ATAC‐seq) is a versatile and widely utilized method for identifying potential regulatory regions, such as promoters and enhancers, within a ...

Chromatin: The nucleosome unwrapped [PDF]

Current Biology, 1997
The structure of the nucleosome core particle has been determined by X-ray crystallography at 2.8 A resolution. The structure has several significant surprises, and provides important new insights into the structure and function of chromatin.

Key Regulators of Parasite Biology Viewed Through a Post‐Translational Modification Repertoire

PROTEOMICS, EarlyView.
ABSTRACT Parasites are the leading causes of morbidity and mortality in both humans and animals, imposing substantial socioeconomic burdens worldwide. Controlling parasitic diseases has become one of the key issues in achieving “One Health”. Most parasites have sophisticated life cycles exhibiting progressive developmental stages, morphologies, and ...

Inactivation of Histone Chaperone HIRA Unmasks a Link Between Normal Embryonic Development of Melanoblasts and Maintenance of Adult Melanocyte Stem Cells

Aging Cell, EarlyView.
Expression of HIRA in embryonic melanoblasts is required for proper epigenetic programing and lineage differentiation. Although HIRA deficiency results in a mild phenotype at birth and young adulthood, the melanocytic lineage is sensitive to proliferative challenge, prone to loss of stem cells and dramatically accelerated hair greying in later life ...

hTERT Increases TRF2 to Induce Telomere Compaction and Extend Cell Replicative Lifespan

Aging Cell, EarlyView.
In contrast to the dogma that a subset of short telomeres initiates senescence, hTERT variants unable to maintain telomere length block senescence by stabilizing TRF2 via inhibiting upstream E3 ubiquitin ligases. This noncanonical hTERT function also compacts telomeres and blocks senescence‐associated DNA damage signaling. Cancer cells expressing hTERT

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

HN1 Functions in Protein Synthesis Regulation via mTOR‐RPS6 Axis and Maintains Nucleolar Integrity

Cell Proliferation, EarlyView.
HN1 is required for nucleolar homeostasis which is the site of ribosome biogenesis and protein synthesis when its mRNA is knocked down by shRNA, it depletes in cytoplasm and the protein synthesis is downregulated in comparison to controls. Thus, the proliferating cells requiring vast number of nucleosomes, are arrested at S onset.

CENP-C unwraps the human CENP-A nucleosome through the H2A C-terminal tail

, 2019
Centromeres are defined epigenetically by nucleosomes containing the histone H3 variant CENP-A, upon which the constitutive centromere-associated network of proteins (CCAN) is built. CENP-C is considered to be a central organizer of the CCAN.
