FGF18

Area of Science:

• Molecular Biology
• Developmental Biology
• Genetics

Background:

• Fibroblast Growth Factor 18 (FGF18) is a pleiotropic growth factor discovered in 1998.
• It plays a crucial role in cell proliferation, growth, and the homeostasis of multiple tissues, including bone, lung, and the central nervous system.
• FGF18 is encoded by a five-exon gene, producing a 207 amino acid glycosylated protein.

Purpose of the Study:

• To summarize the known functions and implications of Fibroblast Growth Factor 18 (FGF18).
• To highlight the role of FGF18 in tissue development and homeostasis.
• To discuss the association of FGF18 with various diseases.

Main Methods:

• Literature review of FGF18 research.
• Analysis of gene structure and protein characteristics.
• Examination of knockout study phenotypes in model organisms.
• Correlation of FGF18 expression with disease states.

Main Results:

• FGF18 is widely expressed in developing and adult organisms (chickens, mice, humans) across various tissues.
• FGF18 knockout studies in mice result in perinatal lethality with phenotypes including cleft palate, reduced body size, and skeletal deformities.
• FGF18 is implicated in diseases such as idiopathic pulmonary fibrosis, congenital diaphragmatic hernia, and cancers (breast, lung, ovarian).

Conclusions:

• FGF18 is essential for normal development and tissue homeostasis.
• Dysregulation or altered expression of FGF18 is associated with significant developmental abnormalities and a range of serious diseases.
• Further research into FGF18 pathways may offer therapeutic insights for associated conditions.
