Salt glands in exo‐recretohalophytes: Development, physiological functions, and prospects for improving crop salt tolerance

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

Identification of Novel Therapeutic Agent Candidates Through High Throughput Screening With Chemical Library Based on Molecular Subclassification in Canine Histiocytic Sarcoma Cell Lines

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT Effective chemotherapy for canine histiocytic sarcoma (CHS) has yet to be established. In our previous study, CHS cell lines were subclassified into two groups based on their gene expression profiles: Group A and Group B. This study aimed to identify novel therapeutic agents that are effective against each CHS subgroup, and we performed high ...

Endogenous ouabain regulates cell viability

open access: yes, 2012
The endogenous cardiac steroid-like compounds, endogenous ouabain (EO) in particular, are present in the human circulation and are considered putative ligands of the inhibitory binding site of the plasma membrane Na+-K+-ATPase.

A low concentration of ouabain (0.18 µg/kg) enhances hypertension in spontaneously hypertensive rats by inhibiting the Na+ pump and activating the renin-angiotensin system

open access: yesBrazilian Journal of Medical and Biological Research, 2010
We investigated the effects of low ouabain concentrations on systolic (SAP) and diastolic (DAP) arterial pressures and on pressor reactivity in 3-month-old male spontaneously hypertensive rats (SHR). Arterial blood pressure (BP) and pressor reactivity to

Effects of Ouabain, Atropine, and Ouabain and Atropine, on A-V Nodal Conduction in Man [PDF]

open access: yesCirculation Research, 1967
The prolongation of A-V transmission time that occurs with increasing rates of right atrial pacing has been used to study the effect of ouabain and of ouabain plus atropine on A-V nodal conduction in 14 patients with normal A-V nodes. Drugs were injected into the superior vena cava or pulmonary artery over a 1- to 2-min period.

NUDT21 Drives T‐Cell Acute Lymphoblastic Leukemia Through Dual Regulation of Alternative Polyadenylation and Transcriptional Activation

open access: yesAdvanced Science, Volume 13, Issue 34, 19 June 2026.
In summary, our study defines a coordinated oncogenic model in which NUDT21 integrates alternative polyadenylation–dependent UBE2D3 stabilization and transcriptional activation to sustain MYC‐driven T‐ALL cell survival, thereby establishing NUDT21 as a central regulatory node and a promising therapeutic target.

Modulation of TNF‐α mRNA stability by human antigen R and miR181s in sepsis‐induced immunoparalysis

open access: yesEMBO Molecular Medicine, 2014
Immunoparalysis is an important pathological mechanism in sepsis. However, an effective small molecule therapy is lacking. Here, we show that ouabain, a Na+,K+‐ATPase ligand, can reverse immunoparalysis in vitro, in vivo, and in clinical samples. Notably,

Calcium Export from Neurons and Multi-Kinase Signaling Cascades Contribute to Ouabain Neuroprotection in Hyperhomocysteinemia

open access: yesBiomolecules, 2020
Pathological homocysteine (HCY) accumulation in the human plasma, known as hyperhomocysteinemia, exacerbates neurodegenerative diseases because, in the brain, this amino acid acts as a persistent N-methyl-d-aspartate receptor agonist.

Embryonic cerebrospinal fluid pressure in fetal mice in utero: External factors pressurize the intraventricular space

open access: yesDevelopmental Dynamics, Volume 255, Issue 6, Page 533-547, June 2026.
Abstract Background Previous experiments inducing leakage of embryonic cerebrospinal fluid (CSF) suggest the necessity of intraventricular CSF pressure (PCSF) for brain morphogenesis. Nevertheless, how embryonic PCSF occurs is unclear, especially in utero. Results Using a Landis water manometer, we measured PCSF in fetal mice isolated from the amniotic
