AI Article Synopsis

  • MicroRNAs (miRNAs) are small non-coding RNAs around 22 nucleotides long that regulate various biological processes by targeting mRNAs for repression or degradation.
  • The STarMirDB database compiles predictions of miRNA binding sites from studies and allows searches by miRNAs or mRNAs, providing detailed information about target interactions.
  • Results from the database include various structural features and high-resolution diagrams of miRNA:target hybrids for easy visualization and use in research.

Article Abstract

microRNAs (miRNAs) are an abundant class of small endogenous non-coding RNAs (ncRNAs) of ∼22 nucleotides (nts) in length. These small regulatory molecules are involved in diverse developmental, physiological and pathological processes. miRNAs target mRNAs (mRNAs) for translational repression and/or mRNA degradation. Predictions of miRNA binding sites facilitate experimental validation of miRNA targets. Models developed with data from CLIP studies have been used for predictions of miRNA binding sites in the whole transcriptomes of human, mouse and worm. The prediction results have been assembled into STarMirDB, a new database of miRNA binding sites available at http://sfold.wadsworth.org/starmirDB.php . STarMirDB can be searched by miRNAs or mRNAs separately or in combination. The search results are categorized into seed and seedless sites in 3' UTR, CDS and 5' UTR. For each predicted site, STarMirDB provides a comprehensive list of sequence, thermodynamic and target structural features that are known to influence miRNA: target interaction. A high resolution PDF diagram of the conformation of the miRNA:target hybrid is also available for visualization and publication. The results of a database search are available through both an interactive viewer and downloadable text files.

Proteomics- and metabolomics-based analysis of the regulation of germination in Norway maple and sycamore embryonic axes.

Tree Physiol

January 2025

Laboratoire de Biologie du Développement, UMR 7622, Institut de Biologie Paris-Seine (IBPS), Sorbonne Université, CNRS, F-75005 Paris, France.

Norway maple and sycamore belong to the Acer genus and produce desiccation-tolerant and desiccation-sensitive seeds, respectively. We investigated the seed germination process at the imbibed and germinated stages using metabolomic and proteomic approaches to determine why sycamore seeds germinate earlier and are more successful at establishing seedlings than Norway maple seeds under controlled conditions. Embryonic axes and embryonic axes with protruded radicles were analyzed at the imbibed and germinated stages, respectively.

The selection of plant genotypes characterized by wellness and stable growth under drought-stress conditions amid ongoing climate change is an important challenge in forest tree breeding. The introduction of molecular markers will enable efficient selection of breeding materials that are resistant to drought stress in forest trees as well as in crop species. Japanese cedar, Cryptomeria japonica, the most dominant forest species in Japan, grows well on mesic sites and is characterized by intraspecific variation in its drought-stress response.

Jaranol alleviates cognitive impairment in db/db mice through the PI3K/AKT pathway.

Metab Brain Dis

January 2025

Xuzhou Engineering Research Center of Medical Genetics and Transformation, Department of Genetics, Xuzhou Medical University, Xuzhou, 221004, Jiangsu, China.

The widely used Radix Astragali (RA) has significant therapeutic effects on cognitive impairment (CI) caused by type 2 diabetes (T2DM). However, the effective active ingredients and the precise mechanism underly RA alleviation of T2DM-induced CI still require further study. In this study, we aim to elucidate whether and how jaranol, a key effective active ingredient in RA, influences CI in db/db mice.

Artificial Metalloenzymes with Two Catalytic Cofactors for Tandem Abiotic Transformations.

Angew Chem Int Ed Engl

January 2025

EPFL: Ecole Polytechnique Federale de Lausanne, Institute of Chemical Sciences and Engineering, EPFL-ISIC-LSCI, BCH 3305, 1015, Lausanne, SWITZERLAND.

Artificial metalloenzymes (ArMs) enable the integration of abiotic cofactors within a native protein scaffold, allowing for non-natural catalytic activities. Previous ArMs, however, have primarily relied on single cofactor systems, limiting them to only one catalytic function. Here we present an approach to construct ArMs embedding two catalytic cofactors based on the biotin-streptavidin technology.

School of Pharmacy, The Key Laboratory of Prescription Effect and Clinical Evaluation of State Administration of Traditional Chinese Medicine of China, Binzhou Medical University, Yantai, 264003, PR China.

Complete spinal cord injury (SCI) causes permanent locomotor, sensory and neurological dysfunctions. Targeting complex immunopathological microenvironment at SCI sites comprising inflammatory cytokines infiltration, oxidative stress and massive neuronal apoptosis, the conductive oriented nanofiber felt with efficient ROS clearance, anti-inflammatory effect and accelerating neural regeneration is constructed by step-growth addition polymerization and electrostatic spinning technique for SCI repair. The formation of innovative Fe-PDA-PAT chelate in nanofiber felt enhances hydrophilic, antioxidant, antibacterial, hemostatic and binding factor capacities, thereby regulating immune microenvironment of SCI.
