Insulin Receptor-Related Receptor Regulates the Rate of Early Development in .

The orphan insulin receptor-related receptor (IRR) encoded by gene is the third member of the insulin receptor family, also including the insulin receptor (IR) and the insulin-like growth factor receptor (IGF-1R). IRR is the extracellular alkaline medium sensor. In mice, is expressed only in small populations of cells in specific tissues, which contain extracorporeal liquids of extreme pH.

Viral Safety Issues in the Production and Manufacturing of Human Immunoglobulin Preparations from Equine Plasma/Serum.

The current Russian and foreign pharmacopoeias either do not provide any information about existing types of viral diseases in horses or do not present it in full. Data of modern domestic and foreign literature was used to prepare the most complete list of viruses that cause equine diseases including 36 infectious agents, 25 of which are pathogenic for humans, 13 of the 25 of which are widespread throughout Russia. Information is provided on the magnitudes of the disease incubation periods (which are most often within one month), the external clinical signs of these diseases (which can also be asymptomatic), and the maximum possible concentrations of viruses in the blood of horses with these diseases (which can reach 8 log conventional units/mL of blood).

The Cytoskeletal Protein Zyxin Inhibits Retinoic Acid Signaling by Destabilizing the Maternal mRNA of the RXRγ Nuclear Receptor.

Zyxin is an LIM-domain-containing protein that regulates the assembly of F-actin filaments in cell contacts. Additionally, as a result of mechanical stress, Zyxin can enter nuclei and regulate gene expression. Previously, we found that Zyxin could affect mRNA stability of the maternally derived stemness factors of Pou5f3 family in Xenopus laevis embryos through binding to Y-box factor1.

Ensuring Viral Safety of Equine Immunoglobulins during Production.

Equine blood plasma/serum and intermediates must be monitored for the presence of live viruses pathogenic in humans during production of equine immunoglobulins. Information concerning low-cost and simple methods for the detection of live horse viruses pathogenic and non-pathogenic to humans was gained using data of modern domestic and foreign literature. These methods are based on cultivation of these viruses on sensitive biosystems.

Targeted search for scaling genes reveals matrixmetalloproteinase 3 as a scaler of the dorsal-ventral pattern in Xenopus laevis embryos.

How embryos scale patterning according to size is still not fully understood. Through in silico screening and analysis of reaction-diffusion systems that could be responsible for scaling, we predicted the existence of genes whose expression is sensitive to embryo size and which regulate the scaling of embryonic patterning. To find these scalers, we identified genes with strongly altered expression in half-size Xenopus laevis embryos compared with full-size siblings at the gastrula stage.

Cytoskeletal protein Zyxin in embryonic development: from controlling cell movements and pluripotency to regulating embryonic patterning.

The Lim-domain protein Zyxin was initially identified as a minor actin cytoskeleton protein that regulates the assembly and repair of actin filaments. At the same time, additional functions revealed for Zyxin in recent decades indicate that this protein can also play an important role in regulating gene expression and cell differentiation. In this review, we analysed the data in the literature pointing to Zyxin as one of the possible molecular hubs linking morphogenetic cell movements with gene expression, stem cell status regulation and pattern formation during the most complex processes in organism life, embryogenesis.

The Secreted Protein Disulfide Isomerase Ag1 Lost by Ancestors of Poorly Regenerating Vertebrates Is Required for Tail Regeneration.

Warm-blooded vertebrates regenerate lost limbs and their parts in general much worse than fishes and amphibians. We previously hypothesized that this reduction in regenerative capability could be explained in part by the loss of some genes important for the regeneration in ancestors of warm-blooded vertebrates. One of such genes could be , which encodes secreted protein disulfide isomerase of the Agr family.

Using RNA-binding proteins for immunoprecipitation of mRNAs from embryos.

This protocol is developed for identifying mRNAs that form complexes with mRNA-binding proteins (mRBPs) in embryos at different developmental stages. Here, we describe the use of the Ybx1 mRBP for immunoprecipitation-based mRNA isolation. This protocol features the translation of the mRBP of interest directly in living embryos following injection of synthetic mRNA templates encoding a hybrid of this protein with a specific tag.

Protocol for separation of the nuclear and the cytoplasmic fractions of embryonic cells for studying protein shuttling.

This protocol for the separation of nuclear and cytoplasmic fractions of cells of embryos was developed to study changes in the intracellular localization of the Zyxin and Ybx1 proteins, which are capable of changing localization in response to certain stimuli. Western blot analysis allows the quantification of changes in the distribution of these proteins between the cytoplasm and nucleus, whereas the posttranslational modifications specific to each compartment can be identified by changes in electrophoretic mobility. For complete details on the use and execution of this protocol, please refer to Parshina et al.

Spectral properties of triphenyltin chloride toxin and its detectivity by SERS: Theory and experiment.

The triphenyltin chloride (TPhTCl) molecular structure was investigated by Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS) and the density functional theory (DFT) modeling. Several conformers with different ordering of the benzene rings were determined in the gas phase and in the dimethyl sulfoxide (DMSO) medium. It was shown that the dihedral angles describing such ordering can change under room conditions.

Bioinformatics Screening of Genes Specific for Well-Regenerating Vertebrates Reveals c-answer, a Regulator of Brain Development and Regeneration.

The molecular basis of higher regenerative capacity of cold-blooded animals comparing to warm-blooded ones is poorly understood. Although this difference in regenerative capacities is commonly thought to be a result of restructuring of the same regulatory gene network, we hypothesized that it may be due to loss of some genes essential for regeneration. We describe here a bioinformatic method that allowed us to identify such genes.

Agr2-interacting Prod1-like protein Tfp4 from Xenopus laevis is necessary for early forebrain and eye development as well as for the tadpole appendage regeneration.

The Agr family genes, Ag1, Agr2, and Agr3, encode for the thioredoxin domain containing secreted proteins and are specific only for vertebrates. These proteins are attracting increasing attention due to their involvement in many physiological and pathological processes, including exocrine secretion, cancer, regeneration of the body appendages, and the early brain development. At the same time, the mode by which Agrs regulate intracellular processes are poorly understood.

The estimation of Miscanthus×giganteus' adaptive potential for cultivation on the mining and post-mining lands in Ukraine.

The possibility of Miscanthus×giganteus cultivation as an energy crop on the different types of mining rocks was studied. It was revealed that a loess-like loam and red-brown clay with the added black soil were the most suitable for plant growing. The yield of dry above-ground biomass ranged from 4.

The cytoskeletal protein Zyxin interacts with the zinc-finger transcription factor Zic1 and plays the role of a scaffold for Gli1 and Zic1 interactions during early development of Xenopus laevis.

We have shown recently that the cytoskeletal protein Zyxin participates in the fine tuning of the neural plate pattering in Xenopus laevis embryos by modulating activity of one of the effectors of Hedgehog (Shh) signaling cascade, the transcription factor Gli1. In the present work, we show that Zyxin can also interact with the potential modulator of the Shh pathway, the transcription factor Zic1. The interaction of proteins occurs primarily by mean of the zinc-finger domain of Zic1 and 2nd LIM domain of Zyxin.

Ras-dva small GTPases lost during evolution of amniotes regulate regeneration in anamniotes.

In contrast to amniotes (reptiles, birds and mammals), anamniotes (fishes and amphibians) can effectively regenerate body appendages such as fins, limbs and tails. Why such a useful capability was progressively lost in amniotes remains unknown. As we have hypothesized recently, one of the reasons for this could be loss of some genes regulating the regeneration in evolution of amniotes.

[Hygienic standardization of 2-formylphenoxyethane acid in the air of the working zone].

The toxic properties of 2-formylphenoxyethane acid for hygienic standardization in the air of working zone were studied. The substance in the dose equal of DL introduced into the stomach for male rats, male and female mice accounted for 5354, 3698 and 4322 mg/kg. It refers to moderately hazardous substances.

HMG-box factor SoxD/Sox15 and homeodomain-containing factor Xanf1/Hesx1 directly interact and regulate the expression of Xanf1/Hesx1 during early forebrain development in Xenopus laevis.

The homeodomain-containing transcription factor Anf (also known as Rpx/Hesx1 in mammals) plays an important role during the forebrain development in vertebrates. Here we demonstrate the ability of the Xenopus laevis Anf, Xanf1/Hesx1, to directly bind SRY-related HMG-box-containing transcription factor SoxD/Sox15 and to cooperate with the latter during regulating of the expression of Xanf1/Hesx1 own gene. As we have shown by GST pull-down, EMSA and the luciferase reporter assays, Xanf1/Hesx1 and SoxD/Sox15 bind the Xanf1/Hesx1 promoter region counteracting the inhibitory effect of Xanf1/Hesx1 alone.

The presence of Anf/Hesx1 homeobox gene in lampreys suggests that it could play an important role in emergence of telencephalon.

Accumulated evidence indicates that the core genetic mechanisms regulating early patterning of the brain rudiment in vertebrates are very similar to those operating during development of the anterior region of invertebrate embryos. However, the mechanisms underlying the morphological differences between the elaborate vertebrate brain and its simpler invertebrate counterpart remain poorly understood. Recently, we hypothesized that the emergence of the most anterior unit of the vertebrate brain, the telencephalon, could be related to the appearance in vertebrates' ancestors of a unique homeobox gene, Anf/Hesx1(further Anf), which is absent from all invertebrates and regulates the earliest steps of telencephalon development in vertebrates.

[The Point Mutation in NOGGIN2 Protein That Enhances Its Ability to Bind Activin].

Earlier we have revealed the ability of Noggin family proteins to bind a member of the TUF-β superfamily, ActivinB, and to repress the Activin-dependent Smad2 signaling cascade. In the present work we have characterized a mutant of the Xenopus laevis Noggin2, bearing the substitution W203R. We have shown that this point mutation enhances the affinity of Noggin2 to ActivinB, while weakens its affinity to BMP.
