A putative cis-regulatory element near Shox2 in the jerboa genome (Jaculus jaculus) is not sufficient to alter mouse limb bone lengths

Galilea Guerrero, Alexander Y. Liu, Alexander J. Weitzel, Erica G. Gacasan, Michael Hiller, Robert L. Sah, Kimberly L. Cooper

The paper tests a putative cis-regulatory element near Shox2 in jerboas to see if it affects mouse limb bone length, finding no detectable phenotype.

CRISPR-mediated conditional mutagenesis of Smad1/5/8 reveals BMP/GDF signaling restricts postnatal bone overgrowth

Rimma Levina, Alexander J. Weitzel, Alexander Y. Liu, Benjamin E. Low, Pierce W. Ford, Hayley Halaby, Hannah A. Grunwald, Erica G. Gacasan, Yasaman Moharrer, Robert L. Sah, Eric J. Bennett, Joel D. Boerckel, Michael V. Wiles, Kimberly L. Cooper

This paper uses CRISPR-mediated conditional mutagenesis to show BMP/GDF signaling restricts postnatal bone overgrowth by regulating both periosteal and endosteal osteoblasts.

Cellular and molecular mechanisms that shape the development and evolution of tail vertebral proportion in mice and jerboas

Ceri J. Weber, Alexander J. Weitzel, Alexander Y. Liu, Erica G. Gacasan, Robert L. Sah, Kimberly L. Cooper

The paper investigates how vertebrae elongate differently in mice and jerboas to achieve disproportionate tail lengths, identifying NPR3 as a key regulator of skeletal proportion.
