The CaM1‐CBP60b‐MYB77 Transcriptional Cascade Regulates K+ Homeostasis and Salt Tolerance in Barley

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Soil salinity is a major abiotic stress that threatens global crop productivity. Calcium (Ca2+) is a pivotal second messenger in plant stress signalling, but how Ca2+ sensors such as calmodulin (CaM) transcriptionally control ion homeostasis and salt tolerance remains largely understood in crops.

In vitro maturation and fertilization of porcine oocytes and evaluation of male fertility [PDF]

open access: yes, 1990
The objectives of this thesis were to establish incubation systems for in vitro porcine maturation and for in vitro fertilization (IVF), and utilizing these in vitro matured oocytes and in vitro fertilization techniques to determine the difference of ...

De-extinction of the Northern white rhinoceros (Ceratotherium simum cottoni)

open access: yesThe Journal of Reproduction and Development
The last survivors of the northern white rhinoceros (NWR, Ceratotherium simum cottoni), once widespread across Central and East Africa, are two non-reproductive females under continuous human protection. In order to prevent the

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Inhibition of ERK and GSK3 signalling pathways promotes development and expression of pluripotent markers in bovine blastocysts [PDF]

open access: yes, 2012
Embryo-derived pluripotent stem cells (ePSCs) naturally derive from different founder tissues, namely the early and late epiblast, that vary in their cellular characteristics. Recent evidence in mice suggests these sources of starting material correspond

hERG1 channels and potential therapeutics for long QT syndrome

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...

Thyroid antibody positivity in pregnancy is associated with altered reproductive hormone concentrations and placental growth in Lewis rats

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Thyroid antibody positivity (TAb+) in pregnancy is associated with adverse pregnancy outcomes, but the mechanisms are unclear. This study developed a rodent model of TAb+ in pregnancy, induced prior to mating so that TAb+ exposure occurred throughout the pregnancy. TAb+ did not alter thyroid hormone concentrations and had minimal

Identification of a Circular RNA as a Potential Diagnostic and Prognostic Biomarker in Breast Cancer Through Integrated Bioinformatic and Experimental Analyses

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
Forty circular RNAs were found to be significantly dysregulated in microarray datasets. Expression levels of hsa_circ_0000231 were significantly upregulated in breast cancer (BC) tissues, while hsa_circ_0011385 exhibited no significant difference in expression levels. This study also revealed that hsa_circ_0000231/hsa‐miR‐5683/CCNB1 regulatory axis may
