Introduction Small‐cell carcinoma of the urinary bladder has a poor prognosis, and no standard treatment has been established. We encountered a case of a patient with metastasis in which complete response and long‐term survival were obtained by treating the primary lesion with a combination of irinotecan, carboplatin chemotherapy, and radiation therapy.

The multicopy gene Sly represses the sex chromosomes in the male mouse germline after meiosis.
Studies of mice with Y chromosome long arm deficiencies suggest that the male-specific region (MSYq) encodes information required for sperm differentiation and postmeiotic sex chromatin repression (PSCR).

Klinefelter syndrome (KS, 47XXY) is a disorder characterized by sex chromosomal aneuploidy, which may lead to changes in epigenetic regulations of gene expression. To define epigenetic architectures in 47XXY, we annotated DNA methylation in euploid males

Adaptive elastic properties of chromatin fiber [PDF]
Chromatin is a complex of DNA and specific proteins forming an intermediary level of organization of eukaryotic genomes, between double-stranded DNA and chromosome. Within a generic modeling of the chromatin assembly, we investigate the interplay between the mechanical properties of the chromatin fiber and its biological functions.

Model chromatin flows: numerical analysis of linear and nonlinear hydrodynamics inside a sphere [PDF]
We solve a hydrodynamic model of active chromatin dynamics, within a confined geometry simulating the cell nucleus. Using both analytical and numerical methods, we describe the behavior of the chromatin polymer driven by the activity of motors having polar symmetry, both in the linear response regime as well as in the long-term, fully nonlinear regime ...

Abstract Titanium dioxide (TiO2) is used extensively as a white pigment in the food industry, personal care, and a variety of products of everyday use. Although TiO2 has been categorized as a bioinert material, recent evidence has demonstrated different toxicity profiles of TiO2 nanoparticles (NPs) and a potential health risk to humans.

The Drosophila CLAMP protein associates with diverse proteins on chromatin. [PDF]
Gaining new insights into gene regulation involves an in-depth understanding of protein-protein interactions on chromatin. A powerful model for studying mechanisms of gene regulation is dosage compensation, a process that targets the X-chromosome to ...

Dual mechanism of chromatin remodeling in the common shrew sex trivalent (XY 1Y 2)
Here we focus on the XY1Y2 condition in male common shrew Sorex araneus Linnaeus, 1758, applying electron microscopy and immunocytochemistry for a comprehensive analysis of structure, synapsis and behaviour of the sex trivalent in pachytene spermatocytes.

CD226+CD8+ T cells express elevated levels of RUNX2, exhibit higher proliferation capacity, cytokines and cytolytic molecules expression, and migratory capacity. In contrast, CD226−CD8+ T cells display an exhausted phenotype associated with the increased expression of co‐inhibitory receptors and impaired effector functions.

HU308 Mitigates Osteoarthritis by Stimulating Sox9‐Related Networks of Carbohydrate Metabolism
ABSTRACT Osteoarthritis (OA) is characterized by progressive, irreversible erosion of articular cartilage accompanied by severe pain and immobility. This study aimed to assess the effect and mechanism of action of HU308, a selective cannabinoid receptor type 2 (CB2) agonist, in preventing OA‐related joint damage. To test the assumption that HU308 could
