The role of Rho GTPases in facial morphogenesis

Developmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

A maternal dorsoventral prepattern revealed by an asymmetric distribution of ventralizing molecules before fertilization in Xenopus laevis

Frontiers in Cell and Developmental Biology
The establishment of the embryonic dorsoventral axis in Xenopus occurs when the radial symmetry around the egg’s animal-vegetal axis is broken to give rise to the typical symmetry of Bilaterians.

Acquisition of Leftward Flow in Xenopus laevis

Bio-Protocol, 2013
In Xenopus, the left-right axis is established following an extracellular vectorial leftward flow driven by monocilia at the gastrocoel roof plate (GRP) during late gastrulation / neurulation (Schweickert et al., 2007).

Xenopus laevis Oocytes

, 2003
Xenopus oocytes are a versatile expression system particularly suited for membrane transporters and channels. Oocytes have little background activity and therefore offer a very high signal-to-noise ratio for transporter and channel characterization. This chapter provides an overview of the basic methods used for the analysis of membrane transporters in

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Add‐on treatment with vinpocetine reduces seizure frequency and improves comorbidities in patients with loss‐of‐function γ‐aminobutyric acid type A receptor variants

Epilepsia, EarlyView.
Abstract Objective The semisynthetic compound vinpocetine has gained attention as a potential precision medicine for developmental and epileptic encephalopathies caused by loss‐of‐function (LoF) variants in γ‐aminobutyric acid type A (GABAA) receptor genes. As a positive allosteric modulator of GABAA receptors, case reports suggest that vinpocetine can

Experimental Embryology in Xenopus Laevis

Turkish Journal of Biology, 1997
Xenopus laevis Türk bilim adamları için yeni bir hayvan modelidir. Ana amacımız, laboratuvarımızda FETAX testini (Frog Embryos Teratogenesis Assay: Xenopus) kurmaktır. Bu çalışmada, Xenopus'un geniş kullanım alanları tanıtıldıktan sonra laboratuvar koşullarında üreme, besleme, havalandırma ve populasyon yoğunluğu parametreleri sunuldu.

Comparing Transcriptomic Responses to Chemicals Across Six Species Using the EcoToxChip RNASeq Database

Environmental Toxicology and Chemistry, EarlyView.
Abstract The EcoToxChip project includes RNA‐sequencing data from experiments involving model (Japanese quail, fathead minnow, African clawed frog) and ecological (double‐crested cormorant, rainbow trout, northern leopard frog) species at multiple life stages (whole embryo and adult) exposed to eight chemicals of environmental concern known to perturb ...

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.

Sel1l preserves condylar cartilage matrix homeostasis by regulating PERK signaling

Interdisciplinary Medicine, EarlyView.
Our study revealed that the expression of Sel1l was downregulated in OA cartilage and that Sel1l deficiency induced cartilage catabolism. Mechanistically, Sel1l depletion aberrantly activated PERK signaling and resulted in ER stress. PERK inhibition rescued the phenotype of Sel1l‐deficient chondrocytes and alleviated TMJOA pathogenesis.
