The Disobeying 'Soldier': Use of an Achiral Group to Modulate Chiral Induction in PNA Duplexes

open access: yesCHIMIA, 2018
Peptide nucleic acid (PNA) is a synthetic analogue of DNA in which the natural nucleobases A, G, C, and T are linked to an achiral, charge neutral, pseudopeptide backbone.

Predictive efficacy of low burden EGFR mutation detected by next-generation sequencing on response to EGFR tyrosine kinase inhibitors in non-small-cell lung carcinoma. [PDF]

open access: yesPLoS ONE, 2013
Direct sequencing remains the most widely used method for the detection of epidermal growth factor receptor (EGFR) mutations in lung cancer; however, its relatively low sensitivity limits its clinical use.

Understanding extracellular vesicles in antiaging

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Control of electron transfer in DNA by peptide nucleic acids (PNA) [PDF]

open access: yesNucleic Acids Symposium Series, 2000
The one-electron oxidation of PNA-DNA hybrid containing G-triplet sequence was examined. In DNA duplex G-triplet was selectively cleaved by oxidation, whereas in PNA-DNA hybrid cleavage efficiency was extremely lowered. These result suggested that cleavage efficiency of PNA-DNA hybrid was different from that of B-form DNA duplex.

PNA Microprobe for Label-Free Detection of Nucleic Acid Repeat Mutations [PDF]

open access: yes, 2021
We present a PNA-based microprobe sensing platform to detect nucleic acid repeat mutations by electrochemical impedance spectroscopy. The microprobe platform discriminated Huntington’s disease-associated CAG repeats in cell-derived total RNA.

Therapeutic and diagnostic applications of antisense peptide nucleic acids

open access: yesMolecular Therapy: Nucleic Acids
Peptide nucleic acids (PNAs) are synthetic nucleic acid analogs with a neutral N-(2-aminoethyl) glycine backbone. PNAs possess unique physicochemical characteristics such as increased resistance to enzymatic degradation, ionic strength and stability over

The KIF6‐RBP Complex Orchestrates mRNA Transport Required for Sperm Flagellar Assembly

open access: yesAdvanced Science, Volume 13, Issue 52, 18 September 2026.
Two homozygous deleterious KIF6 variants are identified in unrelated men with impaired sperm motility. Mouse models and multi‐omics analyses reveal that KIF6 cooperates with the RNA‐binding proteins FMRP and FXR1 to deliver mRNAs essential for sperm flagellar assembly, linking disrupted mRNA transport to reduced abundance of key structural and ...

Convenient and Scalable Synthesis of Fmoc-Protected Peptide Nucleic Acid Backbone

open access: yesJournal of Nucleic Acids, 2012
The peptide nucleic acid backbone Fmoc-AEG-OBn has been synthesized via a scalable and cost-effective route. Ethylenediamine is mono-Boc protected, then alkylated with benzyl bromoacetate. The Boc group is removed and replaced with an Fmoc group.

Shelterin TPP1 Promotes Hair Regeneration Through Activating Bulge Hair Follicle Stem Cells

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
Elongation of telomeres by increasing TPP1, through genetic and pharmacological approaches, promotes hair follicle bulge stem cell mobilization and migration, leading to accelerated telogen‐to‐anagen transition and hair regeneration. This work identifies TPP1 as a master regulator and therapeutic target for alopecia. ABSTRACT Telomere shortening drives
