Transcriptional Regulation of Cysteine and Methionine Metabolism in Lactobacillus paracasei FAM18149

Frontiers in Microbiology, 2018
Lactobacillus paracasei is common in the non-starter lactic acid bacteria (LAB) community of raw milk cheeses. This species can significantly contribute to flavor formation through amino acid metabolism. In this study, the DNA and RNA of L.

Cloning of the Complete Gene for Carcinoembryonic Antigen [PDF]

, 1990
Carcinoembryonic antigen (CEA) is a widely used tumor marker, especially in the surveillance of colonic cancer patients. Although CEA is also present in some normal tissues, it is apparently expressed at higher levels in tumorous tissues than in ...

Dengue virus 3’ untranslated region regulates RNA genome translation

Abstract Viral antigenic burden drives the inflammation-driven pathophysiology of dengue in humans. Nonetheless, the control of dengue virus (DENV) antigen expression for pathogenicity in humans remain uncertain. Herein, we examined a clinical DENV-3 isolate (Sleman/78), along with its partially and fully attenuated derivatives through 30- (Δ30)

G4‐Ligand‐Directed PROTACs Unveil DR1 as a Novel Ligand‐Co‐Binding G4‐Protein and Reshape G4‐Dependent Transcription

Advanced Science, EarlyView.
G4‐binding proteins (G4BPs) that specifically co‐bind G4s in the presence of small‐molecule ligands represent a critical but unexplored class of proteins. We introduce G4‐Ligand‐Directed PROTACs (G4L‐TACs), a chemical platform that couples G4 ligands (PDS) to E3 recruiters to selectively degrade these ligand‐co‐binding G4BPs.

Programmable RNA N6,2´‐O‐Dimethyladenosine Editing

Advanced Science, EarlyView.
ABSTRACT N6,2’‐O‐dimethyladenosine (m6Am) is a prevalent RNA modification located at the first transcribed nucleotide adjacent to the 5′ cap of mRNAs, where it has been implicated in gene regulation. However, the lack of methods for precise, transcript‐specific manipulation of m6Am has limited its functional dissection.

PTRE-seq reveals mechanism and interactions of RNA binding proteins and miRNAs

Nature Communications, 2018
A large number of RNA binding proteins (RBPs) and miRNAs bind to the 3′ untranslated regions of mRNA, but methods to dissect their function and interactions are lacking.

Directed Evolution Improves the Catalytic Efficiency of APEX2‐Mediated Proximity‐Dependent RNA Labeling

Advanced Science, EarlyView.
ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

Animal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

Mucin Glycoprotein Nanoparticles Enable a Selective Antisense Therapy for Oncogenic MicroRNAs

Advanced NanoBiomed Research, EarlyView.
Mucin glycoproteins are turned into nanoparticles by employing synthetic DNA strands, which have a dual function: they stabilize the nanoparticles and act as binding sites for intracellular miRNA‐21. Thus, upon internalization into tumor cells, these mucin nanoparticles can deplete miRNA‐21 from the cytosol, which induces apoptosis in vitro and in vivo.
