However, the therapeutic applications of miRNAs are severely limited by their biological instability and poor intracellular delivery. Herein, we describe a dual-layers surface engineering strategy to design an efficient miRNA delivery nanosystem based on metal–organic frameworks (MOFs) incorporating lipid coating. The resulting nanoparticle system was demonstrated to protect miRNA from ribonuclease degradation, enhance cellular uptake and facilitate lysosomal escape. These ensured effective miRNA mediated gene therapy, which synergized with MOF-specific photodynamic therapy and pre-encapsulated doxorubicin (Dox) chemotherapy to provide a multifunctional with therapeutic effectiveness against cencer cells The mechanisms of miRNA binding and Dox loading were revealed, demonstrating the potential of the present MOFs surface-engineered strategy to overcome their inherent pore-size restriction for macromolecular miRNA carrying, enableefficient co-delivery.

Understanding the basic biology of autoimmune diseases goes hand in hand with providing the clinics with valuable biomarkers for managing these diseases. The focus of this review is paid to localised scleroderma, an autoimmune disease affecting skin and subcutaneous tissue. Localised scleroderma has very few serological biomarkers for clinical analyses distinguishing it from main differentials, and yet noneffective prognostic biomarkers. With this regard, the review covers well-established and new biomarkers such as cell surface proteins, autoantibodies and cytokines. In recent few years, several new biomarkers have been suggested, many provided with modern genomic studies. This includes epigenetic regulation of DNA, RNA transcriptomics and regulatory RNA such as microRNA and long non-coding RNA. These findings can for the first time shed light on the genetic mechanisms behind the disease and contribute to improved diagnosis and treatment.", author = "Adri{\'a}n Hern{\'a}ndez-Bustos and Begona Bolos and Kira Astakhova", note = "Publisher Copyright: {\textcopyright} 2024 The Authors.

We show that the new set of LNA-NN parameters achieves an improved prediction of 0.88 ◦C over older parameter sets that achieve 1.7 °C for this data. We also tested if the existing salt corrections for DNA could be used for LNA as well. Using a small set of low salt melting temperatures we show that by applying the usual DNA salt corrections one may obtain predictions within an average uncertainty of 3.0 °C.

DNA-based STR profiling is a robust method for genetic identification purposes such as forensics and biobanking and for identifying specific molecular subtypes of cancer. STR detection requires polymerase amplification, which introduces errors that obscure the correct genotype. We developed a new method that requires no polymerase. First, we synthesized perylene-nucleoside reagents and incorporated them into oligonucleotide probes that recognize five common human STRs. Using these probes and a bead-based hybridization approach, accurate STR detection was achieved in only 1.5 h, including DNA preparation steps, with up to a 1000-fold target DNA enrichment. This method was comparable to PCR-based assays. Using standard fluorometry, the limit of detection was 2.00 ± 0.07 pM for a given target. We used this assay to accurately identify STRs from 50 human subjects, achieving >98\% consensus with sequencing data for STR genotyping.", author = "\{Hern{\'a}ndez Bustos\}, Adri{\'a}n and Elisa Martiny and \{Bom Pedersen\}, Nadia and Parvathaneni, \{Rohith Pavan\} and Jonas Hansen and Ji, \{Hanlee P.\} and Kira Astakhova", note = "Publisher Copyright: {\textcopyright} 2023 American Chemical Society.

The Mg2+ and Mg2++ K+ results are compared to previous calculations for sodium ions (Na+), in terms of equivalent sodium concentration and ionic strength. Morse potentials, related to hydrogen bonding, were found to be essentially constant and unaffected by cation conditions. However, for stacking interactions we find a clear dependence with ionic strength and cation valence. The highest ionic strength variations, for both hydrogen bonds and stacking interactions, was found at the sequence terminals.

In addition, the mesoscopic parameters can be used to optimize LNA insertion in probes, to achieve accurate melting temperature predictions, and to obtain duplex opening profiles at the base-pair level. Here, we applied this type of model to parameterize a large set of melting temperatures for LNA-modified sequences, from published sources, covering all possible nearest-neighbor configurations. We have found a very large increase in Morse potentials, which indicates very strong hydrogen bonding as the main cause of improved LNA thermodynamic stability. LNA-modified adenine-thymine (AT) was found to have similar hydrogen bonding to unmodified cytosine-guanine (CG) base pairs, while for LNA CG, we found exceptionally large hydrogen bonding. In contrast, stacking interactions, which were thought to be behind the stability of LNA, were similar to unmodified DNA in most cases. We applied the new LNA parameters to the design of BRAF, KRAS, and EGFR oncogene variants by testing all possible LNA modifications. Selected sequences were then synthesized and had their hybridization temperatures measured, achieving a prediction accuracy within 1 °C. We performed a detailed base-pair opening analysis to discuss specific aspects of these probe hybridizations that may be relevant for probe design.", author = "Izabela Ferreira and Sofie Slott and Kira Astakhova and Gerald Weber", year = "2021", doi = "10.1021/acs.jcim.1c00470", language = "English", volume = "61", pages = "3615--3624", journal = "Journal of Chemical Information and Modeling", issn = "1549-9596", publisher = "American Chemical Society", number = "7", } .

Fluorescent Oligonucleotides with Bis(prop-2-yn-1-yloxy)butane-1,3-diol Scaffold Rapidly Detect Disease-Associated Nucleic Acids @article{9d43560fa7fb4dc5bddaa2cb3cf3da05, title = "Fluorescent Oligonucleotides with Bis(prop-2-yn-1-yloxy)butane-1,3-diol Scaffold Rapidly Detect Disease-Associated Nucleic Acids", abstract = "Biomedical research and clinical work demand rapid and reliable detection of disease-associated nucleic acids. Fluorescent oligonucleotides that bind precisely, and sense target DNA or RNA, are useful tools for simple hybridization-based assays. Although a plethora of oligonucleotide modifications are reported in the literature, they often result in poor coupling yields and are very expensive. We describe the synthesis of a new bisalkyne butane-1,3-diol scaffold and its efficient coupling into oligonucleotide sequences. We hypothesized that covalent attachment of multiple (2/4) fluorescent groups to the scaffold within oncogene-specific oligonucleotides could lead to beneficial detection of target DNA. To test this, we post-synthetically conjugated the oligonucleotides with azide-derivative dyes (2/4 per sequence): perylene, 5JOE, and (phenylethynyl)pyrene. We investigated the biophysical and photophysical properties of the oligonucleotide-dye conjugates and confirmed a {"}light up{"} fluorescent sensing mechanism of the probes upon target binding. However, fluorescence of the probes was not sensitive to mismatches. Nevertheless, {"}clicked{"} probes showed a high specificity of binding to complementary target, with the difference in Tm over 10 °C for matched vs mismatched duplex. When applied together, the mismatch-induced difference in temperature melting and fluorescence-based discrimination of the target-bound vs single-stranded probe state allowed us to apply the perylene conjugates to detect mutations in human oncogenes. Due to the beneficial target binding properties of the perylene labeled probes, along with the high fluorescence intensity of probe:target duplexes, human oncogenes could be detected in a convenient and fast (2.5 h) bead-based assay.", author = "Maria Taskova and Kira Astakhova", year = "2019", doi = "10.1021/acs.bioconjchem.9b00746", language = "English", volume = "30", pages = "3007--3012", journal = "Bioconjugate Chemistry", issn = "1043-1802", publisher = "American Chemical Society", number = "12", } .

LB0002 a first in class therapeutic nanoparticle for specific targeting of anti-citrullinated protein antibody ameliorates serum transfer and collagen induced arthritis @article{8eb3c0dc18274486a4f79bda709bab9f, title = "LB0002 a first in class therapeutic nanoparticle for specific targeting of anti-citrullinated protein antibody ameliorates serum transfer and collagen induced arthritis", abstract = "Background: Rheumatoid arthritis (RA) is an immune mediated inflammatory disease with autoimmune features, including antibodies to citrullinated proteins and peptides (ACPAs). Several in vitro studies have suggested a pathogenic role of ACPAs in RA. However, in vivo proof of this concept has been hampered by the lack of therapeutic strategies to reduce or deplete ACPA in serum and synovial fluid. Previously, we constructed a chitosan-hyaluronic acid nanoparticle formulation with the ability to use neutrophil recruitment as a delivery mechanism to inflamed joints. Specifically, nanoparticles got phagocytosed and then released to synovial fluid upon death of the short-lived neutrophils Objectives: We hypothesized that reducing ACPA levels would have a therapeutic effect by blocking cytokine production. In this study, we prepared and tested a series of therapeutic nanoparticles for specific targeting of ACPA in synovial fluid. Methods: Nanoparticles were prepared by the microdroplet method and then decorated with synthetic cyclic citrullinated peptide aptamer PEP2, PEG/hexanoic acid and fluorophore (Cy5.5). Nanoparticles were characterized by dynamic light scattering (DLS), scanning electron microscopy (SEM) and high-performance liquid chromatography (HPLC). Nanoparticles were then used in a series of in vitro assays, including cell uptake with flow cytometry (FACS) detection, and in vivo studies including disease activity scores, cytokine measurements and near-infrared imaging. Results: We screened a series of citrullinated peptide epitopes and identified a fibrinogen-derived 21-amino-acid-long citrullinated peptide showing high selectivity toward autoantibodies in RA samples. We incorporated this aptamer in the chitosan-hyaluronic acid nanoparticle formulation previously described. Average nanoparticle size was 230 nm ± 10 nm by DLS and SEM; z potential was -0.0012. Purity by HPLC was over 95\%. Attachment efficiency of the aptamer was 92\% by HPLC. FACS study showed selective uptake of Cy5.5 labelled aptamer-nanoparticle conjugates by neutrophils in the concentration range 0.5-4 nM. Similar to previous studies,1 there was no apparent immunogenicity for this nanoparticle formulation measured by cytokine secretion from human peripheral blood leukocytes. In vivo, over 50\% reduction of disease activity was achieved in three weeks treatment using as little as 1 nM drug candidate (dosed every 48 hours) in the collagen-induced (CIA) mouse model of RA (N=30; p<0.001 for treated vs placebo). Same was observed in the serum transfer model (N=10). The aptamer-nanoparticle conjugate significantly reduced IL-6 and TNFα levels in the mouse sera (p<0.01). The effects were not inferior to tocilizumab treated controls (N=30). To confirm mode of action, we applied Cy5.5-labelled aptamer-nanoparticles in the collagen-induced mouse model (N=10) and analyzed the resulting uptake by near-infrared imaging. We confirmed over 6-fold higher signal accumulation in inflamed vs healthy joints (p<0.01), which strongly supports the fact that the aptamer is highly specific to the inflammatory process. Conclusion: Overall, we have designed a first-in-class therapeutic nanoparticle drug for specific targeting of anti-citrullinated protein antibodies. The marked effect of this nanoparticle observed in vivo holds promise for targeting ACPAs as a therapeutic option in RA.", author = "Sangita Khatri and J.
