Development of multidrug antibiotic resistance in bacteria is a predicament encountered worldwide. Researchers are in a constant hunt to develop effective antimicrobial agents to counter these dreadful pathogenic bacteria. Here we describe a chimerically engineered multimodular enzybiotic to treat a clinical isolate of methicillin-resistant (). The cell wall binding domain of phage ϕ11 endolysin was replaced with a truncated and more potent cell wall binding domain from a completely unrelated protein from a different phage. The engineered enzybiotic showed strong activity against clinically relevant methicillin-resistant . In spite of a multimodular peptidoglycan cleaving catalytic domain, the engineered enzybiotic could not exhibit its activity against a veterinary isolate of . Our studies point out that novel antimicrobial proteins can be genetically engineered. Moreover, the cell wall binding domain of the engineered protein is indispensable for a strong binding and stability of the proteins.

A well-constructed pollen wall is essential for pollen fertility, which relies on the contribution of tapetum. Our results demonstrate an essential role of the tapetum-expressed protein phosphatase 2A (PP2A) B'α and B'β in pollen wall formation. The b'aβ double mutant pollen grains harbored sticky remnants and tectum breakages, resulting in failed release.

The mitochondrial voltage-dependent anion channel (VDAC) is the major channel in the mitochondrial outer membrane for metabolites and ions. VDACs also regulate a variety of biological processes, which vary in the number of VDAC isoforms across different eukaryotes. However, little is known about VDAC-mediated biocontrol traits in biocontrol fungi.

Mammalian blood cells originate from specialized 'hemogenic' endothelial (HE) cells in major arteries. During the endothelial-to-hematopoietic transition (EHT), nascent hematopoietic stem cells (HSCs) bud from the arterial endothelial wall and enter circulation, destined to colonize the fetal liver before ultimately migrating to the bone marrow. Mechanisms and processes that facilitate EHT and the release of nascent HSCs are incompletely understood, but may involve signaling from neighboring vascular endothelial cells, stromal support cells, circulating pre-formed hematopoietic cells, and/or systemic factors secreted by distal organs.

The aim of this study was to elucidate the impact of porcine pancreatic enzymes (Creon pancrelipase) in comparison to microbial-derived alpha amylase (MD amylase) on the small intestine wall structure, mucosal glycogen accumulation, and enterocyte turnover. The impact of enzyme supplementation on the small intestine was explored in 18 pigs with surgically induced exocrine pancreatic insufficiency (EPI). Four healthy pigs served as the control group.
