Here, we present a systematic approach for developing physiologically relevant, sensitive and specific in vivo assays for interpreting variation in human pathology. Transient genetic manipulation via microinjection of WT and mutant human mRNA and morpholino (MO) antisense oligonucleotides harness the tractability of the developing zebrafish embryo to rapidly assay pathogenic mutations, especially, but not exclusively, in the context of human developmental disorders.

Development of a Neonatal Piglet Acute Lung Injury Model Recreating the Early Environment of Preterm Infant Lungs

This protocol describes the development of a neonatal piglet model of acute lung injury that models early pathogenic events occurring in the preterm lung, including sub-adequate surfactant quantity, hyperoxia, high-pressure ventilation, and inflammation, to facilitate understanding of molecular triggers of bronchopulmonary dysplasia and enhance therapeutic translation.

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules. Skeletal Model Simpler two-dimensional representations of chemical compounds are accomplished using skeletal models. The illustration shows only the molecular framework or bonds without explicitly showing the atoms. In this representation, many of the carbon atoms...

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the nucleus...

Reactive oxygen species rise when oxygen exposure exceeds physiological conditions, increasing oxidative stress. If antioxidant defenses cannot contain this burden, tissue barriers become vulnerable to injury. In the lung, damage to epithelial and endothelial barriers provides a mechanistic link between oxygen excess and impaired tissue integrity, making barrier protection a central outcome to examine.
Beyond direct injury, excess oxygen can activate innate immune pathways and inflammatory signaling. These responses explain why hyperoxia is studied not only as an oxidative damage model but also as an inflammation model. In pulmonary experiments, investigators can examine how this signaling changes leukocyte responses and contributes to altered host defense during respiratory disease.
Hyperoxia can increase lung susceptibility during respiratory disease through the combined effects of oxidative stress, barrier damage, and altered leukocyte responses. Studying these effects together helps investigators examine whether impaired protection reflects changes in the epithelial or endothelial barrier, dysregulated innate responses, or both. That connection is especially relevant to infection-focused pulmonary research.
The model can be implemented with cells, tissues, or whole organisms, depending on the biological question. Researchers expose the selected system to oxygen above normal physiological conditions and then examine injury, inflammation, barrier changes, or immune effects. This flexibility allows experiments to connect cellular responses with tissue-level and organism-level features of pulmonary disease.
Useful outcomes include evidence of oxygen-induced injury, inflammatory activation, impaired epithelial or endothelial barrier function, and changes in pulmonary leukocyte responses or host defenses. In infection-focused studies, these observations can show how oxidative stress modifies tissue susceptibility during respiratory disease. The model therefore supports both mechanistic analysis and evaluation of disease-relevant immune consequences.
A Hyperoxia Model can be used to assess potential therapies that protect barrier function or regulate inflammation. Treatment effects can be interpreted alongside measures of oxygen-induced injury, inflammatory signaling, and immune changes, rather than as a single outcome. In immunology and infection research, this approach clarifies whether an intervention limits tissue damage and how it affects pulmonary host defense.
