Genome‐wide pleiotropy analysis of longitudinal blood pressure and harmonized cognitive performance measures

Alzheimer's &Dementia, Volume 21, Issue 9, September 2025.
Abstract INTRODUCTION Identifying pleiotropy for blood pressure (BP) and cognitive performance measures may indicate mechanistic links between hypertension and Alzheimer's disease (AD). METHODS We performed a pleiotropy genome‐wide association study (GWAS) for paired measures of systolic, diastolic, pulse, and mean arterial pressure with memory ...

NaBC1 Boron Transporter Enables Myoblast Response to Substrate Rigidity via Fibronectin‐Binding Integrins

Advanced Science, Volume 12, Issue 20, May 29, 2025.
Cells transduce the rigidity of the environment into biochemical cues through mechanotransductive cascades that modulate cell behavior. Here, a novel role for the boron transporter NaBC1 is identified as a mechanotransducer involved in regulating cell behavior via specific crosstalk with fibronectin‐binding integrins.

Interactions of Nereistoxin and Its Analogs with Vertebrate Nicotinic Acetylcholine Receptors and Molluscan ACh Binding Proteins

Marine Drugs, 2022
Nereistoxin (NTX) is a marine toxin isolated from an annelid worm that lives along the coasts of Japan. Its insecticidal properties were discovered decades ago and this stimulated the development of a variety of insecticides such as Cartap that are ...

Estradiol deficiency as a consequence of aging contributes to the depletion of the satellite cell pool in female mice

Aging Cell, Volume 24, Issue 4, April 2025.
In females, estradiol deficiency is a major environmental factor contributing to the age‐associated effects on satellite cells. To assess cell‐intrinsic versus environmental regulation of satellite cells, we perform two transplantation experiments, Adult or Aged satellite cells transplanted into Adult recipients, and Adult satellite cells transplanted ...

Local and global calcium signals associated with the opening of neuronal alpha7 nicotinic acetylcholine receptors

, 2009
Neuronal nicotinic acetylcholine receptors (nAChRs) are Ca(2+)-permeable ligand-gated channels widely expressed in the central and peripheral nervous system.

Identification of (24E)-3 alpha,7 alpha-dihydroxy-5 beta-cholest-24-enoic acid and (24R,25S)-3 alpha,7 alpha,24-trihydroxy-5 beta-cholestanoic acid as intermediates in the conversion of 3 alpha,7 alpha-dihydroxy-5 beta-cholestanoic acid to chenodeoxycholic acid in rat liver homogenates.

Journal of Lipid Research, 1994
Studies of chemical structure of the intermediates in the biosynthetic sequence between 3 alpha,7 alpha-dihydroxy-5 beta-cholestanoic acid (DHCA) and chenodeoxycholic acid have been undertaken. Radiolabeled DHCA was incubated with a rat liver preparation.

Transcriptomic Profiling Reveals 17β‐Estradiol Treatment Represses Ubiquitin‐Proteasomal Mediators in Skeletal Muscle of Ovariectomized Mice

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 1, February 2025.
ABSTRACT Background With a decline of 17β‐estradiol (E2) at menopause, E2 has been implicated in the accompanied loss of skeletal muscle mass and strength. We aimed at characterizing transcriptomic responses of skeletal muscle to E2 in female mice, testing the hypothesis that genes and pathways related to contraction and maintenance of mass are ...

The nicotinic alpha7 acetylcholine receptor agonist ssr180711 is unable to activate limbic neurons in mice overexpressing human amyloid-beta1-42

, 2008
Recent studies have demonstrated that amyloid-beta1-42 (Abeta1-42) binds to the nicotinergic alpha7 acetylcholine receptor (alpha7 nAChR) and that the application of Abeta1-42 to cells inhibits the function of the alpha7 nAChR.

Identification of (22R)-3 alpha,7 alpha,12 alpha,22- and (23R)-3 alpha,7 alpha,12 alpha,23-tetrahydroxy-5 beta-cholestanoic acids in urine from a patient with Zellweger's syndrome.

Journal of Lipid Research, 1989
The nature of two novel C27 bile acids present as the taurine conjugates in urine from a patient with Zellweger's syndrome was studied. Bile acids conjugated with taurine were isolated from unconjugated and glycine-conjugated bile acids by means of ion ...

Matrix Metalloproteinase‐Responsive Controlled Release of Self‐Assembly Nanoparticles Accelerates Heart Valve Regeneration In Situ by Orchestrating Immunomodulation

Advanced Science, Volume 12, Issue 2, January 13, 2025.
After implantation of the immunoregulatory scaffold into the body, infiltrated immune cells produce MMP, enabling the degradation of MMP‐responsive hydrogels. Subsequently, galactose‐modified nanoparticles are exposed and phagocytosed by macrophages, triggering their transformation into an anti‐inflammatory phenotype.
