rs. There does not appear to be an increased fracture risk with the use of dapagliflozin or empagliflozin. Given the possible association between canagliflozin and adverse bone outcomes described in CANVAS, canagliflozin use should be pursued in individuals with T2DM only after careful consideration of the individual's skeletal risk.
Osteogenesis imperfecta (OI) is a chronic disease with few treatment options available. The purpose of this review is to provide an overview on treating OI with mesenchymal stem cells (MSC).

Off-the-shelf MSC have a good safety profile and exhibit multilineage differentiation potential and a low immunogenic profile and are easy to manufacture. Selleck SGC 0946 Their ability to migrate, engraft, and differentiate into bone cells, and also to act via paracrine effects on the recipient's tissues, makes MSC candidates as a clinical therapy for OI. Due to their high osteogenic potency, fetal MSC offer an even higher therapeutic potential in OI compared with MSC derived from adult sources. Preclinical and initial clinical data support the use of MSC in treating OI. The characteristics of MSC make them of great interest in treating OI. MSC may be safely transplanted via intravenous administration and show potential positive clinical effects.

Here, we describe a modular RNA labeling method based on a posttranscriptional Suzuki-Miyaura coupling reaction, which works under mild conditions and enables the direct installation of various biophysical reporters and tags. This two-part procedure involves the incorporation of a halogen-modified UTP analog (5-iodouridine-5'-triphosphate) by a transcription reaction. Subsequent posttranscriptional coupling with boronic acid/ester substrates in the presence of a palladium catalyst provides access to RNA labeled with (a) fluorogenic environment-sensitive nucleosides for probing nucleic acid structure and recognition, (b) fluorescent probes for microscopy, and (3) affinity tags for pull-down and immunoassays. It is expected that this method could also become useful for imaging nascent RNA transcripts in cells if the nucleotide analog can be metabolically incorporated and coupled with reporters by metal-assisted cross-coupling reactions.Translating ribosome affinity purification (TRAP) technology allows the isolation of polysomal complexes and the RNAs associated with at least one 80S ribosome. TRAP consists of the stabilization and affinity purification of polysomes containing a tagged version of a ribosomal protein. Quantitative assessment of the TRAP RNA is achieved by direct sequencing (TRAP-SEQ), which provides accurate quantitation of ribosome-associated RNAs, including long noncoding RNAs (lncRNAs). Here we present an updated procedure for TRAP-SEQ, as well as a primary analysis guide for identification of ribosome-associated lncRNAs. This methodology enables the study of dynamic association of lncRNAs by assessing rapid changes in their transcript levels in polysomes at organ or cell-type level, during development, or in response to endogenous or exogenous stimuli.Argonaute proteins play a central role in the evolutionarily conserved mechanisms of RNA silencing. Programmed by a variety of small RNAs, including miRNAs, they recognize their target nucleic acids and modulate gene expression by various means. Argonaute proteins are large complex molecules. Therefore, to better understand the mechanisms they use to regulate gene expression, it is necessary to identify regions of them bearing functional importance (protein-protein interaction surfaces, acceptor sites of posttranslational modifications, etc.). Identification of these regions can be performed using a variety of mutant screens. Here we describe a transient reporter assay system, which is suitable to carry out rapid functional assessment of mutant Argonaute molecules before proceeding to their more detailed biochemical characterization.Polyethylene glycol transfection of plant protoplasts represents an efficient method to incorporate foreign DNA and study transient gene expression. Here, we describe an optimized protocol to deliver small noncoding RNAs into Arabidopsis thaliana protoplasts. An example of application is provided by demonstrating the incorporation of a 20 nt long small noncoding RNA deriving from the 5' extremity of an A. thaliana cytosolic alanine tRNA into freshly isolated protoplasts.Cells have sophisticated RNA-directed mechanisms to regulate genes, destroy viruses, or silence transposable elements (TEs). In terrestrial plants, a specialized non-coding RNA machinery involving RNA polymerase IV (Pol IV) and small interfering RNAs (siRNAs) targets DNA methylation and silencing to TEs. Here, we present a bioinformatics protocol for annotating and quantifying siRNAs that derive from long terminal repeat (LTR) retrotransposons. The approach was validated using small RNA northern blot analyses, comparing the species Arabidopsis thaliana and Brachypodium distachyon. To assist hybridization probe design, we configured a genome browser to show small RNA-seq mappings in distinct colors and shades according to their nucleotide lengths and abundances, respectively. Samples from wild-type and pol IV mutant plants, cross-species negative controls, and a conserved microRNA control validated the detected siRNA signals, confirming their origin from specific TEs and their Pol IV-dependent biogenesis. Moreover, an optimized labeling method yielded probes that could detect low-abundance siRNAs from B.
