Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Effective RNAi-mediated β2-microglobulin loss of function by transgenesis in Xenopus laevis

Biology Open, 2013
Summary To impair MHC class I (class I) function in vivo in the amphibian Xenopus, we developed an effective reverse genetic loss of function approach by combining I-SceI meganuclease-mediated transgenesis with RNAi technology.

Cross‐Linking Mass Spectrometry of the Antimicrobial Peptides Magainin 2 and PGLa Reveals Heterodimerization in Micellar Medium

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale In this study, we applied cross‐linking mass spectrometry (XL‐MS) to characterize the oligomeric states of a PGLa/magainin 2 mixture and gain insight into the heterodimerization previously suggested in the literature. Both peptides have shown a synergistic enhancement of activity when tested in antimicrobial assays; however, the ...

T-cells and transplantation tolerance in Thymectomised Xenopus implanted with foreign thymus [PDF]

, 1990
This thesis investigates the expression of a T-cell differentiation antigen, (XTLA- 1), in various strains and species of Xenopus, and demonstrates the effect of early-thymectomy, (by microcautery), on XTLA-1 expression.

Kaiso is a genome-wide repressor of transcription that is essential for amphibian development [PDF]

, 2004
DNA methylation in animals is thought to repress transcription via methyl-CpG specific binding proteins, which recruit enzymatic machinery promoting the formation of inactive chromatin at targeted loci.

Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)

Integrative Zoology, EarlyView.
Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

Chromosome‐Level Genome Assembly of Strauchbufo raddei and Multi‐Omic Insights Into Drought Adaptation

Integrative Zoology, EarlyView.
ABSTRACT Understanding how amphibians adapt to terrestrial and arid environments is important for elucidating vertebrate terrestrialization. In this study, we present the first chromosome‐level, high‐quality genome assembly of Strauchbufo raddei, constructed using PacBio HiFi long‐read sequencing and Hi‐C scaffolding. The assembled genome is 4.47 Gb in

Maternal Wnt/β-catenin signaling coactivates transcription through NF-κB binding sites during Xenopus axis formation. [PDF]

, 2012
Maternal Wnt/β-Catenin signaling establishes a program of dorsal-specific gene expression required for axial patterning in Xenopus. We previously reported that a subset of dorsally expressed genes depends not only on Wnt/β-Catenin stimulation, but also ...
