An improved bacterial single-cell RNA-seq reveals biofilm heterogeneity

eLife
In contrast to mammalian cells, bacterial cells lack mRNA polyadenylated tails, presenting a hurdle in isolating mRNA amidst the prevalent rRNA during single-cell RNA-seq. This study introduces a novel method, ribosomal RNA-derived cDNA depletion (RiboD),

Small RNA driven feed-forward loop: Fine-tuning of protein synthesis through sRNA mediated cross-talk [PDF]

arXiv, 2019
Often in bacterial regulatory networks, small noncoding RNAs (sRNA) interact with several mRNA species. The competition among mRNAs for binding to the same pool of sRNA might lead to crosstalk between the mRNAs. This is similar to the competing endogenous RNA (ceRNA) effect wherein the competition to bind to the same pool of miRNA in Eukaryotes leads ...

3D Microtumors Representing Ovarian Cancer Minimal Residual Disease Respond to the Fatty Acid Oxidation Inhibitor Perhexiline

Advanced Healthcare Materials, EarlyView.
Minimal residual disease (MRD) leads to cancer relapse and poor survival in ovarian cancer. The lack of representative 3D models limits therapy development. The microfluidics‐based high throughput 3D microtumor platform described here generates clinically‐relevant MRD models. The 3D microtumors recapitulate the molecular signatures of MRD from patients.

Characterizing living ocular bacterial communities and the effects of antibiotic perturbation in house finches

MicrobiologyOpen
DNA‐based methods to measure the abundance and relative abundance of bacterial taxa can be skewed by the presence of dead or transient bacteria. Consequently, the active, functional members of the community may be a small subset of the detected bacterial

RNA-seq reproducibility of Pseudomonas aeruginosa in laboratory models of cystic fibrosis

Microbiology Spectrum
Reproducibility is a fundamental expectation in science and enables investigators to have confidence in their research findings and the ability to compare data from disparate sources, but evaluating reproducibility can be elusive. For example, generating

Secreted bacterial RNA: an unexplored avenue [PDF]

FEMS Microbiology Letters, 2018
Gradually, it is becoming clear that our well-being depends significantly on the contribution and composition of microorganisms that are associated with us. The majority of human-associated microorganisms are bacteria, which maintain their niche through interactions with the human host and neighboring microorganisms.

Organoid‐Like Neurovascular Spheroids Promote the Recovery of Hypoxic‐Ischemic Skin Flaps Through the Activation of Autophagy

Advanced Healthcare Materials, EarlyView.
Highly sprouting organoid‐like neurovascular spheroids (NVUs) are developed, featuring cell‐loaded poly‐3‐hydroxybutyrate 4‐hydroxybutyrate(P34HB) porous microsphere cores embedded within Gelatin Methacryloyl. NVUs formed complex vascular plexuses and secreted extracellular matrix in vitro, simulating autologous nerves and blood interaction.

In silico Analysis Suggests Common Appearance of scaRNAs in Type II Systems and Their Association With Bacterial Virulence

Frontiers in Genetics, 2018
In addition to its well-established defense function, CRISPR/Cas can also exhibit crucial non-canonical activity through endogenous gene expression regulation, which was found to mainly affect bacterial virulence.

Bacterial Pathogenicity Regulation by RNA-binding Antiterminators [PDF]

arXiv
Antiterminators are essential components of bacterial transcriptional regulation, allowing the control of gene expression in response to fluctuating environmental conditions. RNA-binding antiterminators are particularly important regulatory proteins that play a significant role in preventing transcription termination by binding to specific RNA ...

Transcribing RNA polymerases: Dynamics of Twin Supercoiled Domains [PDF]

Gene transcription by a RNA Polymerase (RNAP) enzyme requires that double-stranded DNA be locally and transiently opened, which results in an increase of DNA supercoiling downstream of the RNAP and a decrease of supercoiling upstream of it. When the DNA is initially torsionally relaxed and the RNAP experiences sufficiently large rotational drag, these ...
