Evidence for Gastrointestinal Infection of SARS-CoV-2

medRxiv, 2020
The new coronavirus (SARS-CoV-2) outbreak originating from Wuhan, China, poses a threat to global health. While it's evident that the virus invades respiratory tract and transmits from human to human through airway, other viral tropisms and transmission ...

SARS-CoV-2 variant biology: immune escape, transmission and fitness

Nature Reviews Microbiology, 2023
In late 2020, after circulating for almost a year in the human population, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exhibited a major step change in its adaptation to humans. These highly mutated forms of SARS-CoV-2 had enhanced rates

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Conservation and divergence of bHLH genes in the calcisponge Sycon ciliatum

EvoDevo, 2016
Background Basic Helix-Loop-Helix (bHLH) genes encode a large family of eukaryotic transcription factors, categorized into six high-order groups: pan-eukaryotic group B involved in regulation of cell cycle, metabolism, and development; holozoan-specific ...

Hox gene expression during development of the phoronid Phoronopsis harmeri

EvoDevo, 2020
Background Phoronida is a small group of marine worm-like suspension feeders, which together with brachiopods and bryozoans form the clade Lophophorata. Although their development is well studied on the morphological level, data regarding gene expression

SAR-SIFT: A SIFT-Like Algorithm for SAR Images [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2015
The scale-invariant feature transform (SIFT) algorithm and its many variants are widely used in computer vision and in remote sensing to match features between images or to localize and recognize objects. However, mostly because of speckle noise, it does not perform well on synthetic aperture radar (SAR) images.

Functional assessment of cell entry and receptor usage for SARS-CoV-2 and other lineage B betacoronaviruses

Nature Microbiology, 2020
Over the past 20 years, several coronaviruses have crossed the species barrier into humans, causing outbreaks of severe, and often fatal, respiratory illness. Since SARS-CoV was first identified in animal markets, global viromics projects have discovered

Delivery of DNA‐encoded vaccines and proteins in mice using cutaneous suction‐mediated transfection

FEBS Open Bio, EarlyView.
Cutaneous suction‐mediated transfection in mice for delivery of DNA‐encoded vaccines and proteins. A critical limitation of DNA vaccines and other therapeutics is transfection in vivo to produce the encoded antigens or therapeutic proteins. Cutaneous suction‐based methods have demonstrated effectiveness in many animal models and have been successfully ...

The nascent RNA labelling compound 5-ethynyl uridine (EU) integrates into DNA in some animals

BMC Molecular and Cell Biology
Background The detection of de novo synthesized mRNA transcripts is crucial for understanding the regulation of eukaryotic transcription. Using nucleoside or nucleotide analogues to label nascent RNA is potentially jeopardized by the ubiquitous presence ...

Co-expression of xenopsin and rhabdomeric opsin in photoreceptors bearing microvilli and cilia

eLife, 2017
Ciliary and rhabdomeric opsins are employed by different kinds of photoreceptor cells, such as ciliary vertebrate rods and cones or protostome microvillar eye photoreceptors, that have specialized structures and molecular physiologies.
