Peptide nucleic acids (PNAs) are synthetic mimics of DNA with a pseudo-peptide backbone, offering high affinity and specificity in hybridizing with complementary DNAs or RNAs due to their uncharged and flexible polyamide structure. These unique properties have led to the development of various research assays and diagnostic applications. PNAs have proven their utility in molecular biology procedures and are now used as molecular hybridization probes, antigene and anticancer drugs, PCR reaction modulators, genomic mutation detectors, and chromosome labeling tools.
PNAs, introduced by Nielsen et al., feature a synthetic DNA analog structure with a pseudo-peptide backbone made of N-(2-aminoethyl) glycine units. These backbones provide PNAs with higher stability and a higher thermal melting temperature (Tm) compared to natural DNA or RNA duplexes. PNAs are also resistant to nucleases and proteases, extending their lifespan both in vivo and in vitro.

PNAs have diverse applications across various fields, including:
PNAs can inhibit gene transcription and translation by binding tightly to DNA or mRNA. They can form stable complexes with DNA, blocking transcriptional elongation and inhibiting transcription factor binding. PNAs also interact with mRNA, causing steric interference with RNA processing, transport, or translation.
PNAs can be used to enhance gene transfer efficiency in nonviral gene therapy by linking peptides, drugs, or tracers to plasmid vectors, aiding gene delivery and tissue-specific targeting.
PNAs can terminate the elongation of oligonucleotide primers in PCR reactions by binding to the template or competing with primers. PNA-directed PCR clamping uses PNAs to inhibit specific target amplification, useful for mutation screening and gene isolation.
PNAs are employed for sequence-specific capture of single-stranded nucleic acids, utilizing their tight complex formation at low ionic strength. This technique is useful for purifying nucleic acids and detecting specific DNA sequences.
PNAs offer advantages in hybridization applications due to their tighter binding and higher specificity. They can accelerate procedures in standard hybridization techniques, such as Southern and Northern blotting, and pregel hybridization.
Peptide nucleic acids are versatile and powerful tools in molecular genetics and cytogenetics, with applications ranging from gene therapy to diagnostic assays. Their unique properties make them valuable for a wide range of molecular biology and medical applications.

Therapeutic and diagnostic applications of antisense peptide nucleic acids. (MacLelland, V.; et al, 2024)
In a study focusing on Alzheimer's disease, antisense peptide nucleic acids (PNAs) were designed to target amyloid precursor protein (APP) mRNA. These PNAs were conjugated with cell-penetrating peptides to facilitate crossing the blood-brain barrier and delivery to neuronal cells. The treatment in a mouse model resulted in a significant reduction of amyloid-beta plaques, improved cognitive function, and decreased neuroinflammation. Despite these promising outcomes, challenges such as large-scale synthesis, potential off-target effects, and efficient delivery methods need to be addressed. This study highlights the potential of PNAs as a therapeutic approach for neurodegenerative diseases, underscoring the need for further development and optimization.
PNA vaccine refers to the use of PNA (peptide nucleic acid) as one of the core technologies of the vaccine. This technique utilizes PNA molecules to design and synthesize vaccines, which are commonly used to improve immune response and enhance vaccine stability and efficacy.
Antisense peptide nucleic acids (PNAs) are gene expression modification techniques that block the translation process of RNA by binding to complementary sequences of target genes. PNAs are different from DNA or RNA in that their skeleton is composed of N-(2-aminoethyl) glycine units, which are highly chemically stable and selective. While, antisense oligonucleotides (ASOs) are short DNA or RNA molecules that are able to bind to complementary sequences of target RNA to form double - or triple-stranded structures. This binding can block the translation of the target RNA or enhance its degradation, thereby regulating the expression of the target gene. ASO has important application value in gene silencing, gene modification and treatment of genetic diseases.
PNA (peptide nucleic acid) is a synthetic DNA simulator with high chemical stability and biological activity. Its primary function is as a analog of DNA and RNA in molecular biology research, for exploration of genomics, drug discovery, and the development of diagnostic tools.
A peptide nucleic acid probe (PNA probe) is a synthetic nucleic acid analogue that has peptide bonds rather than glycoside bonds to connect bases. The probe can bind specifically to DNA or RNA sequences for molecular biology research and diagnostic applications.
A nucleic acid probe is a short strand of DNA or RNA that is used to detect a specific sequence of nucleic acids. They recognize and detect the presence and location of the target DNA or RNA by binding specifically to the target sequence. Nucleic acid probes are widely used in molecular biology and medical diagnostics to help scientists study gene function, detect pathogens, and diagnose genetic diseases.
