PEX1 is essential for glycosome biogenesis and trypanosomatid parasite survival.

Trypanosomatid parasites are kinetoplastid protists that compartmentalize glycolytic enzymes in unique peroxisome-related organelles called glycosomes. The heterohexameric AAA-ATPase complex of PEX1-PEX6 is anchored to the peroxisomal membrane and functions in the export of matrix protein import receptor PEX5 from the peroxisomal membrane. Defects in PEX1, PEX6 or their membrane anchor causes dysfunction of peroxisomal matrix protein import cycle.

Modeling gut microbe interactions reveals metabolic interconnectivity.

We know a lot about varying gut microbiome compositions. Yet, how the bacteria affect each other remains elusive. In mammals, this is largely based on the sheer complexity of the microbiome with at least hundreds of different species.

Zinc accelerates respiratory burst termination in human PMN.

The respiratory burst of phagocytes is essential for human survival. Innate immune defence against pathogens relies strongly on reactive oxygen species (ROS) production by the NADPH oxidase (NOX2). ROS kill pathogens while the translocation of electrons across the plasma membrane via NOX2 depolarizes the cell.

Herbivory and leaf expansion of Cyathea phalerata Mart. (Cyatheaceae) in subtropical Atlantic Forest, southern Brazil.

Herbivory is an interaction with great impact on plant communities since relationships between herbivores and plants are fundamental to the distribution and abundance of species over time and space. The aim of this study was to monitor the rate of leaf expansion in the tree fern Cyathea phalerata and evaluate the damage caused by herbivores to leaves of different ages and whether such damage is related to temperature and precipitation. The study was performed in a subtropical Atlantic Forest fragment located in the municipality of Caraá, in the northeast hillside of Rio Grande do Sul state, in southern Brazil.

Control of Drosophila Growth and Survival by the Lipid Droplet-Associated Protein CG9186/Sturkopf.

Lipid droplets (LDs) are the universal cellular storage organelles for esterified neutral lipids. The increasing number of characterized LD-associated proteins attained LDs with hitherto unexpected functions on top of their classical role as energy depot. Here, we characterize the LD-associated protein CG9186 of Drosophila by a CRISPR/Cas9-derived mutant fly line.

Penaeid shrimp brachyury: sequence analysis and expression during gastrulation.

Gastrulation occurs by a variety of morphogenetic movements, often correlated with diverse expression of the T-box transcription factor Brachyury (Bra). Bra may be expressed in ectoderm, mesoderm, or endoderm, but its role in cell fate specification or regulation of gastrulation movements has not been studied in the development of crustaceans. Penaeid shrimp (Decapoda: Dendrobranchiata: Penaeidae) develop by complete cleavage and gastrulation by invagination to a free-swimming nauplius larva.

The impact of genome variation and diet on the metabolic phenotype and microbiome composition of Drosophila melanogaster.

The metabolic phenotype of an organism depends on a complex regulatory network, which integrates the plethora of intrinsic and external information and prioritizes the flow of nutrients accordingly. Given the rise of metabolic disorders including obesity, a detailed understanding of this regulatory network is in urgent need. Yet, our level of understanding is far from completeness and complicated by the discovery of additional layers in metabolic regulation, such as the impact of the microbial community present in the gut on the hosts' energy storage levels.

[Surgical Treatment of Pseudotumours of the Lung].

Introduction: Pseudotumour of the lung is a collective term for various subentities. Some subgroups are considered to be intermediary malignant tumours. A pseudotumour is a rare condition, which makes it difficult to estimate its incidence and prevalence.

Regulation of Gonad Morphogenesis in Drosophila melanogaster by BTB Family Transcription Factors.

During embryogenesis, primordial germ cells (PGCs) and somatic gonadal precursor cells (SGPs) migrate and coalesce to form the early gonad. A failure of the PGCs and SGPs to form a gonad with the proper architecture not only affects germ cell development, but can also lead to infertility. Therefore, it is critical to identify the molecular mechanisms that function within both the PGCs and SGPs to promote gonad morphogenesis.
