Large Oncosomes Induce Pro‐Metastatic Stromal‐Myeloid Reprogramming

Advanced Science, EarlyView.
Large oncosomes systemically reprogram bone marrow mesenchymal stem cells through innate nucleic acid sensing, driving inflammatory and immunosuppressive remodeling that supports a metastasis‐permissive bone marrow environment, revealing a novel tumor‐host communication axis in cancer. ABSTRACT Bone metastasis can be facilitated by systemic remodeling,

Plasma Membrane Lipid Asymmetry Dynamically Regulates Passive Diffusion

Advanced Science, EarlyView.
Passive diffusion enables hydrophobic molecules to cross the plasma membrane and exert their biological functions. This study demonstrates that plasma membrane lipid asymmetry, dynamically regulated by lipid scrambling, determines membrane permeability to lipophilic molecules and thereby modulates their cellular activities.

Binding of 9-cis-retinoic acid and all-trans-retinoic acid to retinoic acid receptors alpha, beta, and gamma. Retinoic acid receptor gamma binds all-trans-retinoic acid preferentially over 9-cis-retinoic acid

Journal of Biological Chemistry, 1994
Both 9-cis-retinoic acid (RA) and all-trans-RA (t-RA) compete for [3H]9-cis-RA binding to RA receptors (RAR alpha, beta, and gamma) in nucleosol fractions from transiently transfected COS-1 cells with IC50 values of approximately 12 and 5 nM, respectively.

Chromosomal Abnormalities, Drug Sensitivity and Resistance in Hematological Malignancies: A Comprehensive Overview by the Francophone Group of Hematological Cytogenetics (GFCH)

American Journal of Hematology, EarlyView.
ABSTRACT Chromosomal abnormalities have a major clinical impact on hematological malignancies, particularly with regard to treatment strategies. To preserve and consolidate fundamental knowledge in this rapidly evolving field, the Francophone Group of Hematological Cytogenetics (Groupe Francophone de Cytogénétique Hématologique, GFCH) conducted a ...

Enzymology of retinoic acid biosynthesis and degradation

Journal of Lipid Research, 2013
All-trans-retinoic acid is a biologically active derivative of vitamin A that regulates numerous physiological processes. The concentration of retinoic acid in the cells is tightly regulated, but the exact mechanisms responsible for this regulation are ...

First Report of Uniparental Isodisomy of Chromosome 15 Revealing Angelman Syndrome and Microphthalmia Associated With a Novel Homozygous ALDH1A3 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Paternal isodisomy of chromosome 15 (iUPD15) is a recognized cause of Angelman syndrome (AS), accounting for approximately 2%–5% of cases. Additionally, another recognized consequence of iUPD is the unmasking of autosomal recessive disorders. However, reports of recessive disorders resulting from iUPD15 remain scarce in the literature.

UBE3A Dosage Imbalance as a Molecular Framework Linking Angelman Syndrome and Dup15q‐Associated Autism Phenotypes

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT UBE3A is a dosage‐sensitive HECT E3 ubiquitin ligase whose neuronal expression is shaped by genomic imprinting at the 15q11.2‐q13 locus. Opposite directions of UBE3A dosage imbalance contribute to distinct neurodevelopmental phenotypes: loss of maternal UBE3A underlies Angelman syndrome, whereas maternally derived 15q11.2‐q13 copy‐number gains,

The Role of Retinoic Acid in Spermatogenesis and Its Application in Male Reproduction

Cells
Spermatogenesis in mammalian testes is essential for male fertility, ensuring a continuous supply of mature sperm. The testicular microenvironment finely tunes this process, with retinoic acid, an active metabolite of vitamin A, serving a pivotal role ...
