Candidatus Nitrosocaldus cavascurensis, an Ammonia Oxidizing, Extremely Thermophilic Archaeon with a Highly Mobile Genome

Frontiers in Microbiology, 2018
Ammonia oxidizing archaea (AOA) of the phylum Thaumarchaeota are widespread in moderate environments but their occurrence and activity has also been demonstrated in hot springs. Here we present the first enrichment of a thermophilic representative with a

Diverse Asgard archaea including the novel phylum Gerdarchaeota participate in organic matter degradation

Science China Life Sciences, 2020
Asgard is an archaeal superphylum that might hold the key to understand the origin of eukaryotes, but its diversity and ecological roles remain poorly understood.

Quorum Sensing Inhibits Type III‐A CRISPR‐Cas System Activity Through Repressing Positive Regulators SarA and ArcR in Staphylococcus Aureus

Advanced Science, EarlyView.
This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.

Engineered crRNA Drives RPA‐T7‐CRISPR/Cas14a Cascade for Ultrasensitive Detection of ctDNA PIK3CA H1047R

Advanced Science, EarlyView.
The TIDE‐Cas14a system, an integrated RPA‐T7‐CRISPR/Cas14a cascade platform incorporating engineered crRNA mismatches, enables ultrasensitive detection of the PIK3CA H1047R mutation in breast cancer circulating tumor DNA, with a limit of detection as low as 0.01%, surpassing the sensitivity of droplet digital PCR.

Insights into the Mechanisms of Immune‐Checkpoint Inhibitors Gained from Spatiotemporal Dynamics of the Tumor Microenvironment

Advanced Science, EarlyView.
This review summarizes recent advances in the spatiotemporal dynamics of the tumor microenvironment (TME). It highlights the roles of diverse immune and stromal cell populations, spatial architecture of the TME, as well as the gut and tumor microbiota in influencing responses to immune checkpoint inhibitors (ICIs), by integrating insights from single ...

Identification of novel components of the Ced and Ups systems in Saccharolobus islandicus REY15A

mLife
In Sulfolobales cells, transcription of the Ups (UV‐inducible pili of Sulfolobus) and Ced (Crenarchaeal system for exchange of DNA) genes is highly induced by DNA damage, and the two systems play key roles in pili‐mediated cell aggregation and ...

The cardiolipin analogues of Archaea

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2009
The present article reviews studies of the structure and functional roles of the cardiolipin analogues of extremely halophilic prokaryotes belonging to the Archaea domain. Analogies and differences between the archaeal bisphosphatidylglycerol and the mitochondrial cardiolipin are presented. Furthermore the structure of archaeal glycophospholipid dimers

Graphitized Biochar Derived from Agricultural Wastes Enhances Methanogenesis via Conductivity‐Driven Direct Interspecies Electron Transfer

Advanced Science, EarlyView.
This work clarifies how feedstocks and their structural features promote methanogenesis, and identifies the key regulatory factors, reducing pollution to the global environment, and also helps to alleviate the energy crisis. This is the first study to systematically link feedstock lignin content, pyrolysis conditions, biochar graphitization, and DIET ...
