The HECT ubiquitin-protein ligases UPL1 and UPL2 are involved in degradation of Arabidopsis thaliana ACC synthase 7.

Ethylene is an important plant hormone whose production relies on the action of key enzymes, one of which is 1-aminocyclopropane-1-carboxylate synthase (ACS). There are three classes of ACS, which are all partially regulated by degradation through the ubiquitin-proteasome system (UPS), which regulates ethylene production. Arabidopsis has a single class III ACS, ACS7, but although it is known to be degraded by the 26S proteasome, the UPS proteins involved are poorly characterised.

ATG8 delipidation is not universally critical for autophagy in plants.

Intracellular recycling via autophagy is governed by post-translational modifications of the autophagy-related (ATG) proteins. One notable example is ATG4-dependent delipidation of ATG8, a process that plays critical but distinct roles in autophagosome formation in yeast and mammals. Here, we aim to elucidate the specific contribution of this process to autophagosome formation in species representative of evolutionarily distant green plant lineages: unicellular green alga Chlamydomonas reinhardtii, with a relatively simple set of ATG genes, and a vascular plant Arabidopsis thaliana, harboring expanded ATG gene families.

SPOCK2 controls the proliferation and function of immature pancreatic β-cells through MMP2.

Human pluripotent stem cell-derived β-cells (SC-β-cells) represent an alternative cell source for transplantation in diabetic patients. Although mitogens could in theory be used to expand β-cells, adult β-cells very rarely replicate. In contrast, newly formed β-cells, including SC-β-cells, display higher proliferative capacity and distinct transcriptional and functional profiles.

Ethnogenetic analysis reveals the Bronze Age genetic affiliation of Yashkuns with West Eurasians.

Modern Plant Breeding for Achieving Global Food Security.

Modern plant breeding technologies have played a central role in addressing global food security challenges. These technologies, including next-generation sequencing (NGS) and multi-omics analysis, genome-wide association analysis (GWAS), genome editing and transgenics, machine learning, and speed breeding, have been improving crop yield and quality as well as crop adaptability under climate change conditions, such as tolerance to both biotic and abiotic stresses. Furthermore, identification, searching, assessment, and combining desirable integrated (morphological, physiological, and biochemical) attributes have been achieved with greater accuracy, efficiency, time, and cost-effectiveness, all of which are essential to meeting global food demands.

Repeated toluene inhalation in male and female adolescent rats induces persistent drug preference and impairs cognitive and social behavior.

Rationale: Adolescent inhalant use is an understudied and undertreated disorder, particularly in females. Chronic exposure to inhalants, like toluene, can have long-lasting effects on behavior. However, most animal studies lack the incorporation of both sexes and do not focus on the abstinence period.

Efficient RNA extraction method for acquiring high-quality RNA from various tissues of the fiber crop abaca, Née.

Isolation of high-quality RNA from abaca is very challenging due to the presence of polyphenols, polysaccharides, and its high fiber content. In this study, we compared six extraction methods across three tissue types and different developmental stages (-grown young versus field-grown mature tissue). The Invitrogen PureLink RNA kit proved to be the most efficient in extracting RNA from young abaca tissues (leaves, pseudostem, and corm).

Developing a Novel and Optimized Yeast Model for Human VDAC Research.

The voltage-dependent anion-selective channel (VDAC) plays a crucial role in mitochondrial function, and VDAC paralogs are considered to ensure the differential integration of mitochondrial functions with cellular activities. Heterologous expression of VDAC paralogs in the yeast Δ mutant cells is often employed in studies of functional differentiation of human VDAC paralogs (hVDAC1-hVDAC3) regardless of the presence of the yeast second VDAC paralog (yVDAC2) encoded by the gene. Here, we applied ΔΔ double mutants and relevant Δ and Δ single mutants, derived from two strains (M3 and BY4741) differing distinctly in auxotrophic markers but commonly used for heterologous expression of hVDAC paralogs, to study the effect of the presence of yVDAC2 and cell genotypes including , the latter resulting in a low level of hydrogen sulfide (HS), on the complementation potential of heterologous expression of hVDAC paralogs.

Backstage Heroes-Yeast in COVID-19 Research.

The extremely rapid development of understanding and technology that led to the containment of the COVID-19 pandemic resulted from collaborative efforts in the fields of (SARS-CoV-2) biology, pharmacology, vaccinology, and medicine. Perhaps surprisingly, much of the research was conducted using simple and efficient yeast models. In this manuscript, we describe how yeast, eukaryotic microorganisms, have been used to research this global challenge, focusing on the therapeutic potential of the studies discussed herein.

Water Migration through Enzyme Tunnels Is Sensitive to the Choice of Explicit Water Model.

The utilization of tunnels and water transport within enzymes is crucial for their catalytic function as water molecules can stabilize bound substrates and help with unbinding processes of products and inhibitors. Since the choice of water models for molecular dynamics simulations was shown to determine the accuracy of various calculated properties of the bulk solvent and solvated proteins, we have investigated if and to what extent water transport through the enzyme tunnels depends on the selection of the water model. Here, we focused on simulating enzymes with various well-defined tunnel geometries.

Albumin orchestrates a natural host defense mechanism against mucormycosis.

Mucormycosis is an emerging, life-threatening human infection caused by fungi of the order Mucorales. Metabolic disorders uniquely predispose an ever-expanding group of patients to mucormycosis via poorly understood mechanisms. Therefore, it is highly likely that uncharacterized host metabolic effectors confer protective immunity against mucormycosis.
