This study found widespread localization of parathyroid hormone-related protein in normal and cancerous canine tissues, suggesting a potential physiological role as a paracrine or autocrine factor.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study reports the crystallization of the human androgen receptor's ligand-binding domain with nonsteroidal ligands, which may aid in understanding the differences in binding compared to steroidal ligands.

In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

Keratin-associated proteins may have roles in various mouse tissues, not just hair.

This review discusses the complex role of the EDA pathway in vertebrate skeletal development, emphasizing its interaction with other morphogenic pathways to influence skeletal diversity, but reports no new experimental results.

This review discusses the current understanding of genes coding for hair and avian keratins, highlighting gene structure and protein sequences, but reports no new experimental findings.

In this study, researchers engineered ventral skin organoids (vSkOs) with specific cellular compositions and signaling environments to generate human amnion-like tissues called Amnioids, offering new tools for studying human development and potential regenerative therapies.

This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.

In this study, researchers identified a cluster of hair-specific keratin-associated protein genes within the 21q22.3 region, revealing a novel transcription mechanism involving TSPEAR/C21orf29 that may bypass typical transcriptional termination sites.

This study found that cetaceans have adapted their fibroblast growth factors to assist in low bone density, hypoxia tolerance, and the development of rigid flippers, reflecting significant evolutionary changes for aquatic life.
