Xenopus phospho-CDK7/cyclin H expressed in baculoviral-infected insect cells. by Lawrie, A, Tito, P, Hernandez, H, Brown, N, Robinson, C, Endicott, J, Noble, M, Johnson, L

“…Phosphorylation of CDK7 is essential for cyclin association and kinase activity in the absence of the assembly factor MAT1. The Xenopus laevis CDK7 phosphorylation sites are located on the activation segment of the kinase at residues Ser170 and at Thr176 (the latter residue corresponding to Thr160 in human CDK2). …”

Facile cruciform formation by an (A-T)34 sequence from a Xenopus globin gene. by Greaves, D, Patient, R, Lilley, D

Functional odor map heterogeneity is based on multifaceted glomerular connectivity in larval Xenopus olfactory bulb by Thomas Offner, Lukas Weiss, Daniela Daume, Anna Berk, Tim Justin Inderthal, Ivan Manzini, Thomas Hassenklöver

“…Using functional multiphoton-microscopy and single-cell tracing, we investigate the impact of this wiring on glomerular module organization and odor representations on multiple levels of the Xenopus laevis OB network. The glomerular odor map to amino acid odorants is neither stereotypic between animals nor chemotopically organized. …”

Non-canonical Hedgehog signaling regulates spinal cord and muscle regeneration in Xenopus laevis larvae by Andrew M Hamilton, Olga A Balashova, Laura N Borodinsky

“…Here, we examined Hh signaling during post-amputation tail regeneration in Xenopus laevis larvae. We found that while Smoothened (Smo) activity is essential for proper spinal cord and skeletal muscle regeneration, transcriptional activity of the canonical Hh effector Gli is repressed immediately following amputation, and inhibition of Gli1/2 expression or transcriptional activity has minimal effects on regeneration. …”

The return to water in ancestral Xenopus was accompanied by a novel mechanism for producing and shaping vocal signals by Ursula Kwong-Brown, Martha L Tobias, Damian O Elias, Ian C Hall, Coen PH Elemans, Darcy B Kelley

“…Results refute the current theory for Xenopus vocalization, cavitation, and favor instead sound production by mechanical excitation of laryngeal resonance modes following rapid separation of laryngeal arytenoid discs. …”

Tsukushi modulates Xnr2, FGF and BMP signaling: regulation of Xenopus germ layer formation. by Samantha A Morris, Alexandra D Almeida, Hideaki Tanaka, Kunimasa Ohta, Shin-ichi Ohnuma

“…Members of the TGF-beta family such as activin B, Vg1, derrière and Xenopus nodal-related proteins (Xnrs) are candidate mesoderm inducing factors, with further activity to induce endoderm of the vegetal region. …”

Population genomics and subgenome evolution of the allotetraploid frog <i>Xenopus laevis</i> in southern Africa by Tharindu Premachandra, Caroline M S Cauret, Werner Conradie, John Measey, Ben J Evans

“…To explore the possibility that subgenome population structure and gene flow may differ as well, we examined genetic variation in an allotetraploid frog—the African clawed frog (Xenopus laevis…”

A Developmental Requirement for HIRA-Dependent H3.3 Deposition Revealed at Gastrulation in Xenopus by Emmanuelle Szenker, Nicolas Lacoste, Geneviève Almouzni

“…To assess the importance of the H3.3 histone variant and its dedicated histone chaperone HIRA, we used an established developmental model, Xenopus laevis. After the early rapid divisions exploiting a large maternal pool of both replicative H3.2 and replacement H3.3, H3.3 transcripts show a distinct peak of expression at gastrulation. …”

Modulation of thyroid hormone-dependent gene expression in Xenopus laevis by INhibitor of Growth (ING) proteins. by Caren C Helbing, Mary J Wagner, Katherine Pettem, Jill Johnston, Rachel A Heimeier, Nik Veldhoen, Frank R Jirik, Yun-Bo Shi, Leon W Browder

“…We have previously shown that ING1 and ING2 expression is regulated by thyroid hormone (TH) during metamorphosis of the Xenopus laevis tadpole. The present study investigates the possibility that ING proteins modulate TH action.Tadpoles expressing a Xenopus ING2 transgene (Trans(ING2)) were significantly smaller than tadpoles not expressing the transgene (Trans(GFP)). …”
