The emergence of multiple variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) highlights the importance of possible animal-to-human (zoonotic) and human-to-animal (zooanthroponotic) transmission and potential spread within animal species. A range of animal species have been verified for SARS-CoV-2 susceptibility, either in vitro or in vivo. However, the molecular bases of such a broad host spectrum for the SARS-CoV-2 remains elusive. Here, we structurally and genetically analysed the interaction between the spike protein, with a particular focus on receptor binding domains (RBDs), of SARS-CoV-2 and its receptor angiotensin-converting enzyme 2 (ACE2) for all conceivably susceptible groups of animals to gauge the structural bases of the SARS-CoV-2 host spectrum. We describe our findings in the context of existing animal infection-based models to provide a foundation on the possible virus persistence in animals and their implications in the future eradication of COVID-19.

Transcription takes place over a significant portion of the human genome. However, only a small portion of the transcriptome, roughly 1.2%, consists of RNAs translated into proteins; the majority of transcripts, on the other hand, comprise a variety of RNA families with varying sizes and functions.

Addressing the pressing need to develop affordable and efficient catalysts is essential. In this study, we successfully synthesized CuBiS nanostructures with a modified morphology using three different nitrogen bases: DBN, DBU, and DABCO a hydrothermal technique. These nanostructures were used for the electrochemical detection of organic nitro groups, a previously unexplored application for this material.

Coronaviruses evade detection by the host immune system with the help of the endoribonuclease Nsp15, which regulates levels of viral double stranded RNA by cleaving 3' of uridine (U). While prior structural data shows that to cleave double stranded RNA, Nsp15's target U must be flipped out of the helix, it is not yet understood whether Nsp15 initiates flipping or captures spontaneously flipped bases. We address this gap by designing fluorinated double stranded RNA substrates that allow us to directly relate a U's sequence context to both its tendency to spontaneously flip and its susceptibility to cleavage by Nsp15.

Transcription factors (TFs) recognize specific bases within their DNA-binding motifs, with each base contributing nearly independently to total binding energy. However, the energetic contributions of particular dinucleotides can deviate strongly from the additive approximation, indicating that some TFs can specifically recognize DNA dinucleotides. Here we solved high-resolution (<1 Å) structures of MYF5 and BARHL2 bound to DNAs containing sets of dinucleotides that have different affinities to the proteins.

Article Synopsis
  • The cervical uncinate process, part of the cervical spine, changes with age and may relate to osteoporosis.
  • This study utilized micro-computed tomography (Micro-CT) to analyze the cancellous bone distribution and morphology in the uncinate process from 155 vertebrae (C3-C7).
  • Findings revealed that the cancellous bone is mainly longitudinally aligned, with significant differences in bone surface area between sides, and highlighted C5 as the region most affected by stress and osteoporosis, providing insights for preventing and treating cervical spine-related conditions.
