Summary
Calcitonin (CT) affects bone remodeling by regulating Pate4 gene expression in osteoclasts. Pate4-deficient mice show no significant bone or fertility defects, indicating limited function in these areas.
Area of Science:
- Endocrinology
- Molecular Biology
- Genetics
Background:
- Calcitonin (CT) is a hormone known to negatively regulate bone formation.
- CT inhibits sphingosine-1-phosphate release from osteoclasts.
- CT was observed to repress Pate4 gene expression in osteoclasts.
Purpose of the Study:
- To investigate the function of Pate4 in bone remodeling.
- To generate and analyze Pate4-deficient mice.
- To assess the role of Pate4 in fertility.
Main Methods:
- Generation of Pate4-deficient mice using targeted embryonic stem cells.
- Bone-specific histomorphometric analysis.
- Multi-tissue expression analysis and histological examination of reproductive tissues.
Main Results:
- Pate4-deficient mice were viable and born at the expected Mendelian ratio.
- No significant abnormalities in bone remodeling were observed in Pate4-deficient mice.
- Pate4 is primarily expressed in prostate and seminal vesicles, but these tissues showed no histological abnormalities in deficient mice.
- Pate4 deficiency did not result in reduced fertility.
Conclusions:
- The study generated the first mouse model lacking the Pate4 gene.
- Pate4 plays a limited role in bone remodeling and fertility.
- Pate4's primary expression in reproductive tissues does not correlate with a significant function in fertility.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

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.

01:33Pleiotropy
44.0K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
