Summary
Researchers identified 204 genes impacting mouse vertebral anatomy and development. Many of these genes are novel candidates for human vertebral malformations like scoliosis.
Area of Science:
- Developmental Biology
- Genetics
- Skeletal Biology
Background:
- Vertebral malformations in humans are complex and often have unknown genetic origins.
- The International Mouse Phenotyping Consortium (IMPC) provides a valuable resource for studying gene function in mammals.
Purpose of the Study:
- To identify genes influencing vertebral anatomy and development using a large-scale knockout mouse dataset.
- To explore the expression patterns of these genes during embryonic development.
Main Methods:
- Analysis of 8,539 whole-gene knockouts from the IMPC release 19.
- Categorization of identified genes based on vertebral phenotypes.
- Gene expression analysis in somite tissues across multiple developmental stages.
Main Results:
- Identified 204 genes affecting vertebral anatomy and development, categorized into six groups.
- 182 of these genes are expressed in somites, with significant temporal expression changes.
- Found 14 genes with vertebral defects as their sole phenotype and 34 where it constitutes over 50% of phenotypes.
Conclusions:
- Identified a substantial set of novel candidate genes for human vertebral malformations.
- Highlights the role of somite gene expression in vertebral development.
- Provides a foundation for further research into the genetic basis of spinal defects.

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

01:27Muscles of the Vertebral Column
3.3K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...
