GENES AND DEVELOPMENTAL PATHWAYS

Phenotypic determination of epithelial appendages: genes, developmental pathways, and evolution.

Epithelial appendages are derivatives of epithelia that elaborate to form specialized structures and functions. The appendage can protrude out, such as in teeth and feathers, or invaginate in, such as in glands. The epithelia can be ectodermal, such as in hairs, or endodermal, such as in livers. Using feather as a prototype of epithelial appendage, we study the molecular signals involved in the...

Developmental Pathways in CAVD

Calcific Aortic Valve Disease (CAVD) occurs in >2% of the population over 65 years of age and often leads to valvular stenosis that necessitates valve replacement [1]. CAVD is a pro‐ gressive disease, often manifesting first as aortic valve sclerosis and later developing into stenosis and valve dysfunction [2]. The specific molecular and cellular mechanisms of CAVD initiation and advancement ar...

Identification of key genes and pathways involved in vitiligo vulgaris by gene network analysis

Background and Aim: Vitiligo vulgaris is an acquired, chronic skin and hair condition characterized clinically by loss of melanin, which, if untreated, is typically progressive and irreversible. The aim of the present study was to identify potential genes involved in the pathogenesis of vitiligo. Methods: One dataset of mRNA expression in patients with vitiligo (GSE65127) were obtained from ...

Developmental Pathways To Conduct Problems

Murine developmental control genes.

Various strategies have been used to isolate genes that participate in the regulation of mouse development. Gene families that have been identified on the basis of their homology to motifs within Drosophila control genes or human transcription factor genes, namely homeobox (Hox), paired-box (Pax), and POU genes, can be compared with respect to gene organization, structure, and expression patter...
