CAP-MAP: cap analysis protocol with minimal analyte processing, a rapid and sensitive approach to analysing mRNA cap structures.

ABSTRACT: Eukaryotic messenger RNA (mRNA) is modified by the addition of an inverted guanosine cap to the 5' triphosphate. The cap guanosine and initial transcribed nucleotides are further methylated by a series of cap methyltransferases to generate the mature cap structures which protect RNA from degradation and recruit proteins involved in RNA processing and translation. Research demonstrating that the cap methyltransferases are regulated has generated interest in determining the methylation status of the mRNA cap structures present in cells. Here, we present CAP-MAP: cap analysis protocol with minimal analyte processing, a rapid and sensitive method for detecting cap structures present in mRNA isolated from tissues or cultured cells.

Cap analogs with a hydrophobic photocleavable tag enable facile purification of fully capped mRNA with various cap structures.

Project description:Starting with the clinical application of two vaccines in 2020, mRNA therapeutics are currently being investigated for a variety of applications. Removing immunogenic uncapped mRNA from transcribed mRNA is critical in mRNA research and clinical applications. Commonly used capping methods provide maximum capping efficiency of around 80-90% for widely used Cap-0- and Cap-1-type mRNAs. However, uncapped and capped mRNA possesses almost identical physicochemical properties, posing challenges to their physical separation. In this work, we develop hydrophobic photocaged tag-modified cap analogs, which separate capped mRNA from uncapped mRNA by reversed-phase high-performance liquid chromatography. Subsequent photo-irradiation recovers footprint-free native capped mRNA. This approach provides 100% capping efficiency even in Cap-2-type mRNA with versatility applicable to 650 nt and 4,247 nt mRNA. We find that the Cap-2-type mRNA shows up to 3- to 4-fold higher translation activity in cultured cells and animals than the Cap-1-type mRNA prepared by the standard capping method.

Analysing causal structures with entropy.

Project description:A central question for causal inference is to decide whether a set of correlations fits a given causal structure. In general, this decision problem is computationally infeasible and hence several approaches have emerged that look for certificates of compatibility. Here, we review several such approaches based on entropy. We bring together the key aspects of these entropic techniques with unified terminology, filling several gaps and establishing new connections, all illustrated with examples. We consider cases where unobserved causes are classical, quantum and post-quantum, and discuss what entropic analyses tell us about the difference. This difference has applications to quantum cryptography, where it can be crucial to eliminate the possibility of classical causes. We discuss the achievements and limitations of the entropic approach in comparison to other techniques and point out the main open problems.

Methylation of viral mRNA cap structures by PCIF1 attenuates the antiviral activity of interferon-β.

Project description:Interferons induce cell-intrinsic responses associated with resistance to viral infection. To overcome the suppressive action of interferons and their effectors, viruses have evolved diverse mechanisms. Using vesicular stomatitis virus (VSV), we report that the host cell N6-adenosine messenger RNA (mRNA) cap methylase, phosphorylated C-terminal domain interacting factor 1 (PCIF1), attenuates the antiviral response. We employed cell-based and in vitro biochemical assays to demonstrate that PCIF1 efficiently modifies VSV mRNA cap structures to m7Gpppm6Am and define the substrate requirements for this modification. Functional assays revealed that the PCIF1-dependent modification of VSV mRNA cap structures is inert with regard to mRNA stability, translation, and viral infectivity but attenuates the antiviral effects of the treatment of cells with interferon-β. Cells lacking PCIF1 or expressing a catalytically inactive PCIF1 exhibit an augmented inhibition of viral replication and gene expression following interferon-β treatment. We further demonstrate that the mRNA cap structures of rabies and measles viruses are also modified by PCIF1 to m7Gpppm6Am This work identifies a function of PCIF1 and cap-proximal m6Am in attenuation of the host response to VSV infection that likely extends to other viruses.

An approach to rapid processing of camera trap images with minimal human input.

Project description:Camera traps have become an extensively utilized tool in ecological research, but the manual processing of images created by a network of camera traps rapidly becomes an overwhelming task, even for small camera trap studies.We used transfer learning to create convolutional neural network (CNN) models for identification and classification. By utilizing a small dataset with an average of 275 labeled images per species class, the model was able to distinguish between species and remove false triggers.We trained the model to detect 17 object classes with individual species identification, reaching an accuracy up to 92% and an average F1 score of 85%. Previous studies have suggested the need for thousands of images of each object class to reach results comparable to those achieved by human observers; however, we show that such accuracy can be achieved with fewer images.With transfer learning and an ongoing camera trap study, a deep learning model can be successfully created by a small camera trap study. A generalizable model produced from an unbalanced class set can be utilized to extract trap events that can later be confirmed by human processors.

Elimination of cap structures generated by mRNA decay involves the new scavenger mRNA decapping enzyme Aph1/FHIT together with DcpS.

Project description:Eukaryotic 5' mRNA cap structures participate to the post-transcriptional control of gene expression before being released by the two main mRNA decay pathways. In the 3'-5' pathway, the exosome generates free cap dinucleotides (m7GpppN) or capped oligoribonucleotides that are hydrolyzed by the Scavenger Decapping Enzyme (DcpS) forming m7GMP. In the 5'-3' pathway, the decapping enzyme Dcp2 generates m7GDP. We investigated the fate of m7GDP and m7GpppN produced by RNA decay in extracts and cells. This defined a pathway involving DcpS, NTPs and the nucleoside diphosphate kinase for m7GDP elimination. Interestingly, we identified and characterized in vitro and in vivo a new scavenger decapping enzyme involved in m7GpppN degradation. We show that activities mediating cap elimination identified in yeast are essentially conserved in human. Their alteration may contribute to pathologies, possibly through the interference of cap (di)nucleotide with cellular function.

Implantable Nanotube Sensor Platform for Rapid Analyte Detection.

Project description:The use of nanoparticles within living systems is a growing field, but the long-term effects of introducing nanoparticles to a biological system are unknown. If nanoparticles remain localized after in vivo implantation unanticipated side effects due to unknown biodistribution can be avoided. Unfortunately, stabilization and retention of nanoparticles frequently alters their function.[1] In this work multiple hydrogel platforms are developed to look at long-term localization of nanoparticle sensors with the goal of developing a sensor platform that will stabilize and localize the nanoparticles without altering their function. Two different hydrogel platforms are presented, one with a liquid core of sensors and another with sensors decorating the hydrogel's exterior, that are capable of localizing the nanoparticles without inhibiting their function. With the use of these new hydrogel platforms nanoparticle sensors can be easily implanted in vivo and utilized without concerns of nanoparticle impact on the animal.

Regulation of mRNA cap methylation.

Project description:The 7-methylguanosine cap added to the 5' end of mRNA is essential for efficient gene expression and cell viability. Methylation of the guanosine cap is necessary for the translation of most cellular mRNAs in all eukaryotic organisms in which it has been investigated. In some experimental systems, cap methylation has also been demonstrated to promote transcription, splicing, polyadenylation and nuclear export of mRNA. The present review discusses how the 7-methylguanosine cap is synthesized by cellular enzymes, the impact that the 7-methylguanosine cap has on biological processes, and how the mRNA cap methylation reaction is regulated.

Widespread Influence of 3'-End Structures on Mammalian mRNA Processing and Stability.

Project description:The physiological relevance of structures within mammalian mRNAs has been elusive, as these mRNAs are less folded in cells than in vitro and have predicted secondary structures no more stable than those of random sequences. Here, we investigate the possibility that mRNA structures facilitate the 3'-end processing of thousands of human mRNAs by juxtaposing poly(A) signals (PASs) and cleavage sites that are otherwise too far apart. We find that RNA structures are predicted to be more prevalent within these extended 3'-end regions than within PAS-upstream regions and indeed are substantially more folded within cells, as determined by intracellular probing. Analyses of thousands of ectopically expressed variants demonstrate that this folding both enhances processing and increases mRNA metabolic stability. Even folds with predicted stabilities resembling those of random sequences can enhance processing. Structure-controlled processing can also regulate neighboring gene expression. Thus, RNA structure has widespread roles in mammalian mRNA biogenesis and metabolism.

Long-wavelength analyte-sensitive luminescent probes and optical (bio)sensors.

Project description:Long-wavelength luminescent probes and sensors become increasingly popular. They offer the advantage of lower levels of autofluorescence in most biological probes. Due to high penetration depth and low scattering of red and NIR light such probes potentially enable in vivo measurements in tissues and some of them have already reached a high level of reliability required for such applications. This review focuses on the recent progress in development and application of long-wavelength analyte-sensitive probes which can operate both reversibly and irreversibly. Photophysical properties, sensing mechanisms, advantages and limitations of individual probes are discussed.

Dynamical insight into Caenorhabditis elegans eIF4E recognition specificity for mono-and trimethylated structures of mRNA 5' cap.

Project description:Specific recognition and binding of the ribonucleic acid 5' termini (mRNA 5' cap) by the eukaryotic translation initiation factor 4E (eIF4E) is a key, rate limiting step in translation initiation. Contrary to mammalian and yeast eIF4Es that discriminate in favor of 7-methylguanosine cap, three out of five eIF4E isoforms from the nematode Caenorhabditis elegans as well as eIF4Es from the parasites Schistosome mansoni and Ascaris suum, exhibit dual binding specificity for both 7-methylguanosine-and N(2),N(2),7-trimethylguanosine cap. To address the problem of the differences in the mechanism of the cap recognition by those highly homologic proteins, we carried out molecular dynamics simulations in water of three factors, IFE-3 and IFE-5 isoforms from C. elegans and murine eIF4E, in the apo form as well as in the complexes with 7-methyl-GDP and N(2),N(2),7-trimethyl-GDP. The results clearly pointed to a dynamical mechanism of discrimination between each type of the cap, viz. differences in mobility of the loops located at the entrance into the protein binding pockets during the cap association and dissociation. Additionally, our data showed that the hydrogen bond involving the N(2)-amino group of 7-methylguanosine and the carboxylate of glutamic acid was not stable. The dynamic mechanism proposed here differs from a typical, static one in that the differences in the protein-ligand binding specificity cannot be ascribed to formation and/or disruption of well defined stabilizing contacts.
