    Highly Efficient <i>O</i>-Glycosylations with <i>p</i>-Tolyl Thioribosides and <i>p</i>-TolSOTf

    A wide variety of p-tolyl thioriboside donors are examined for O-ribosylations of primary and secondary alcohols. p-Tolylsulfenyl trifluoromethanesulfonate (p-TolSOTf) is very effective in promoting O-ribosylations with p-tolyl thioriboside; all reactions are completed within 1−15 min to provide the desired products in good yield with reliable α/β selectivity. A wide range of functional groups are tolerated under these conditions. The described O-ribosylation conditions are very useful for the generation of ribosaminouridine library molecules in solution or on polymer support

    Conjugated Polyelectrolyte Amplified Thiazole Orange Emission for Label Free Sequence Specific DNA Detection with Single Nucleotide Polymorphism Selectivity

    No full text
    We report a simple label-free method for sequence specific DNA detection using cationic conjugated polyelectrolyte (CCP) amplified thiazole orange (TO) emission as the signal. The discrimination of perfectly complementary DNA from a one-base mismatched sequence is accomplished by S1 nuclease digestion of the hybridized peptide nucleic acid (PNA)/DNA complexes. When the target DNA is complementary to the PNA probe, the DNA/PNA complexes remain after digestion, which allows TO intercalation to give fluorescence. Addition of CCP to this solution leads to enhanced TO emission due to fluorescence resonance energy transfer (FRET) from the CCP to TO, and the solution fluorescence appears yellow. In the presence of even one base mismatched DNA or double-stranded DNA molecules, S1 nuclease can effectively digest the DNA sequences into small fragments and no dye intercalation occurs. Addition of CCP to these solutions does not induce any polymer fluorescence change, and the solution fluorescent color is blue. This method allows visual detection of target DNA with a detection limit of 5 μM, which provides good groundwork for the future exploration of real-time instrument free single nucleotide polymorphism (SNP) diagnosis

    Background: N7-methylguanosine (m7G) is an emerging research hotspot in the field of RNA methylation, and its role in tumor regulation is becoming increasingly recognized. However, its role in colorectal cancer (CRC) remains unclear. Hence, our study explored the role of m7G in CRC.Methods: The mRNA expression data and the corresponding clinical information of the patients with CRC were obtained from The Cancer Genome Atlas (TCGA). A m7G-related gene pair signature was established using the Cox and LASSO regression analyses. A series of in silico analyses based on the signature included analysis of prognosis, correlation analysis, immune-related analysis, and estimation of tumor mutational burden (TMB), microsatellite instability (MSI), and response to immunotherapy. A nomogram prediction model was then constructed.Results: In total, 2156 m7G-related gene pairs were screened based on 152 m7G-related genes. Then, a prognostic signature of seven gene pairs was constructed, and the patients were stratified into high- or low-risk groups. Better overall survival (OS), left-sided tumor, early stage, immune activity, and low proportion of MSI-low and MSI-high were all associated with a low risk score. High-risk patients had a higher TMB, and patients with a high TMB had a poor OS. Furthermore, the risk score was linked to immune checkpoint expression (including PD-L1), the tumor immune dysfunction and exclusion (TIDE) score, and chemotherapy sensitivity. We also created an accurate nomogram to increase the clinical applicability of the risk score.Conclusion: We identified an m7G pair-based prognostic signature associated with prognosis, immune landscape, immunotherapy, and chemotherapy in CRC. These findings could help us to better understand the role of m7G in CRC, as well as pave the path for novel methods to assess prognosis and design more effective individualized therapeutic strategies.</p
