Abstract
Oxidative DNA damage is closely associated with the occurrence of numerous human diseases and cancers. 8-Oxo-7,8-dihydroguanine (8-oxoG) is the most prevalent form of DNA damage, and it has become not only an oxidative stress biomarker but also a new epigenetic-like biomarker. However, few approaches are available for the locus-specific detection of 8-oxoG because of the low abundance of 8-oxoG damage in DNA and the limited sensitivity of existing assays. Herein, we demonstrate the elongation and ligation-mediated differential coding for label-free and locus-specific analysis of 8-oxoG in DNA. This assay is very simple without the involvement of any specific labeled probes, complicated steps, and large sample consumption. The utilization of Bsu DNA polymerase can specifically initiate a single-base extension reaction to incorporate dATP into the opposite position of 8-oxoG, endowing this assay with excellent selectivity. The introduction of cascade amplification reaction significantly enhances the sensitivity. The proposed method can monitor 8-oxoG with a limit of detection of 8.21 × 10-19 M (0.82 aM), and it can identify as low as 0.001% 8-oxoG damage from a complex mixture with excessive undamaged DNAs. This method can be further applied to measure 8-oxoG levels in the genomic DNA of human cells under diverse oxidative stress, holding prospect potential in the dynamic monitoring of critical 8-oxoG sites, early clinical diagnosis, and gene damage-related biomedical research.

Abstract
Damage of reactive oxygen species to various molecules such as DNA has been related to many chronic and degenerative human diseases, aging, and even cancer. 8-Oxo-7,8-dihydroguanine (OG), the most significant oxidation product of guanine (G), has become a biomarker of oxidative stress as well as gene regulation. The positive effect of OG in activating transcription and the negative effect in inducing mutation are a double-edged sword; thus, site-specific quantification is helpful to quickly reveal the functional mechanism of OG at hotspots. Due to the possible biological effects of OG at extremely low abundance in the genome, the monitoring of OG is vulnerable to signal interference from a large amount of G. Herein, based on rolling circle amplification-induced G-triplex formation and Thioflavin T fluorescence enhancement, an ultrasensitive strategy for locus-specific OG quantification was constructed. Owing to the difference in the hydrogen-bonding pattern between OG and G, the nonspecific background signal of G sites was completely suppressed through enzymatic ligation of DNA probes and the triggered specificity of rolling circle amplification. After the signal amplification strategy was optimized, the high detection sensitivity of OG sites with an ultralow detection limit of 0.18 amol was achieved. Under the interference of G sites, as little as 0.05% of OG-containing DNA was first distinguished. This method was further used for qualitative and quantitative monitoring of locus-specific OG in genomic DNA under oxidative stress and identification of key OG sites with biological function.

Abstract
DNA methylation (5-methylcytosine, 5mC) is the most important epigenetic modification in mammals. Deciphering the roles of 5mC relies on the quantitative detection of 5mC at the single-base resolution. Bisulfite sequencing (BS-seq) is the most often employed technique for mapping 5mC in DNA. However, bisulfite treatment may cause serious degradation of input DNA due to the harsh reaction conditions. Here, we engineered the human apolipoprotein B mRNA-editing catalytic polypeptide-like 3C (A3C) protein to endow the engineered A3C (eA3C) protein with differential deamination activity toward cytosine and 5mC. By the virtue of the unique property of eA3C, we proposed an engineered A3C sequencing (EAC-seq) method for the bisulfite-free and quantitative mapping of 5mC in DNA at the single-base resolution. In EAC-seq, the eA3C protein can deaminate C but not 5mC, which is employed to differentiate C and 5mC in sequencing. Using the EAC-seq method, we quantitatively detected 5mC in genomic DNA of lung cancer tissue. In contrast to the harsh reaction conditions of BS-seq, which could lead to significant degradation of DNA, the whole procedure of EAC-seq is carried out under mild conditions, thereby preventing DNA damage. Taken together, the EAC-seq approach is bisulfite-free and straightforward, making it an invaluable tool for the quantitative detection of 5mC in limited DNA at the single-base resolution.

Abstract
The formation of unnatural base pairs within duplex DNA would facilitate DNA nanotechnology and biotechnology. Iso-2'-deoxyguanosine (iso-dG) forms base pairs with iso-2'-deoxycytidine, and its use as an unnatural base pair was investigated. Iso-dG is one of the tautomers of 2-hydroxy-2'-deoxyadenosine (2-OH-dA), known as an oxidatively damaged nucleobase, and its selective recognition in DNA plays an important role in the diagnosis and pathogenesis of disease. Therefore, we focused on pseudo-dC (ψdC) as a suitable molecule that recognizes 2-OH-dA in DNA. Since 2-OH-dA shows tautomeric structures in DNA, we designed and used ψdC, which also has a tautomeric structure. We successfully synthesized a ψdC phosphoramidite compound for the synthesis of oligonucleotides (ODNs) as well as its triphosphate derivative (ψdCTP). Tm measurements revealed that ODNs including ψdC showed stable base pair formation with ODNs having 2-OH-dA. In contrast, low Tm values were observed for other bases (dG, dA, dC, and T). The results obtained for the single-nucleotide primer extension reaction revealed that ψdCTP was incorporated into the complementary position of 2-OH-dA in template DNA with high selectivity. In addition, the primer elongation reaction was confirmed to proceed in the presence of dNTPs. The present study reports an artificial nucleic acid that selectively and stably forms unnatural base pairs with 2-OH-dA in DNA.

Pleiotropic Roles of Atrial Natriuretic Peptide in Anti-Inflammation and Anti-Cancer Activity. Cancers (Basel) 2022; 14:cancers14163981.

Abstract
Simple Summary The relationship between inflammation and carcinogenesis, as well as the response to anti-tumor therapy, is intimate. Atrial natriuretic peptides (ANPs) play a pivotal role in the homeostatic control of blood pressure, electrolytes, and water balance. In addition, ANPs exert immune-modulatory effects in the tissue microenvironment, thus exhibiting a fascinating ability to prevent inflammation-related tumorigenesis and cancer recurrence. In cancers, ANPs show anti-proliferative effects through several molecular pathways. Furthermore, ANPs attenuate the side effects of cancer therapy. Therefore, ANPs have potential therapeutic value in tumors. Here, we summarized the roles of ANPs in diverse aspects of the immune system and the molecular mechanisms underlying the anti-cancer effects of ANPs, contributing to the development of ANP-based anti-cancer agents. Abstract The atrial natriuretic peptide (ANP), a cardiovascular hormone, plays a pivotal role in the homeostatic control of blood pressure, electrolytes, and water balance and is approved to treat congestive heart failure. In addition, there is a growing realization that ANPs might be related to immune response and tumor growth. The anti-inflammatory and immune-modulatory effects of ANPs in the tissue microenvironment are mediated through autocrine or paracrine mechanisms, which further suppress tumorigenesis. In cancers, ANPs show anti-proliferative effects through several molecular pathways. Furthermore, ANPs attenuate the side effects of cancer therapy. Therefore, ANPs act on several hallmarks of cancer, such as inflammation, angiogenesis, sustained tumor growth, and metastasis. In this review, we summarized the contributions of ANPs in diverse aspects of the immune system and the molecular mechanisms underlying the anti-cancer effects of ANPs.

Abstract
Simple Summary Vincristine is a type of chemotherapy that is often used in the treatment of children with cancer. The main side effect of vincristine is nerve damage. Patients experience symptoms such as tingling, pain or muscle weakness. Some children are more sensitive to vincristine than others, which may depend on variations in genes and in the breakdown of vincristine by the body. In this study, we investigated the effect of variations in genes on nerve damage due to vincristine and breakdown of vincristine by the body. We found that nine variations in seven genes were associated with nerve damage due to vincristine, whereas three variations in three genes were associated with the breakdown of vincristine by the body. It is important that future studies try to replicate these findings. Our findings help us towards the goal of tailoring vincristine treatment to each child, with optimal therapeutic effect while limiting nerve damage. Abstract Vincristine (VCR) is an important component of curative chemotherapy for many childhood cancers. Its main side effect is VCR-induced peripheral neuropathy (VIPN), a dose limiting toxicity. Some children are more susceptible to VIPN, which is at least partially dependent on genetic factors and pharmacokinetics (PK). In this study, we identify and replicate genetic variants associated with VCR PK and VIPN. Patient samples from a randomized clinical trial studying the effect of administration duration of VCR on VIPN in 90 patients were used. PK sampling was conducted on between one and five occasions at multiple time points. A linear two-compartment model with first-order elimination was used, and targeted next-generation DNA sequencing was performed. Genotype–trait associations were analyzed using mixed-effect models or logistic regression analysis for repeated measures, or Poisson regression analysis in which the highest VIPN score per patient was included. Nine single-nucleotide polymorphisms (SNPs) in seven genes (NDRG1, GARS, FIG4, FGD4, SEPTIN9, CEP72, and ETAA1) were associated with VIPN. Furthermore, three SNPs in three genes (MTNR1B, RAB7A and SNU13) were associated with PK of VCR. In conclusion, PK of VCR and VIPN are influenced by SNPs; upfront identification of those that lead to an altered susceptibility to VIPN or VCR exposure could help individualize VCR treatment.

Abstract
Cancer is among the leading causes of death globally. Despite advances in cancer research, a full understanding of the exact cause has not been established. Recent data have shown that the microbiome has an important relationship with cancer on various levels, including cancer pathogenesis, diagnosis and prognosis, and treatment. Since most studies have focused only on the role of bacteria in this process, in this article we review the role of fungi-another important group of the microbiome, the totality of which is referred to as the "mycobiome"-in the development of cancer and how it can impact responses to anticancer medications. Furthermore, we provide recent evidence that shows how the different microbial communities interact and affect each other at gastrointestinal and non-gastrointestinal sites, including the skin, thereby emphasizing the importance of investigating the microbiome beyond bacteria.

Abstract
Oxidative DNA damage is tightly linked to the development of multiple age-related diseases. The prominent oxidation product is 8-oxo-7,8-dihydroguanine (OG), which has been proved to be an important epigenetic-like biomarker. Quantification of the locus-specific OG frequency includes quantitative and locating information, which is of great significance for exploring the functional roles of OG in disease induction and gene regulation. Herein, an ultrasensitive quantification of OG at single-base resolution was established using real-time fluorescence quantitative polymerase chain reaction as an amplification tool. Based on the coding property of Bsu DNA polymerase that incorporates adenine on the opposite site of OG and the selectivity of the ligase for perfectly matched sequences, the difference between OG and G on the sequence could be enlarged. Well-performed Taq DNA ligase was selected out, and as low as 46.2 zmol of target DNA with an OG site and an OG frequency of 5% could be detected. G contents on a specific site were also detectable based on the similar principle, thus the OG frequency of this locus could be accurately determined by a standard addition method. This strategy was successfully applied to the evaluation of locus-specific OG in both model DNA and genomic DNA from human cervical carcinoma cell lines under multiple oxidative stress, showing the potential for functional research and dynamic monitoring of critical OG sites.

Talanta 2022; 243:123340. [PMID: 35272158 DOI: 10.1016/j.talanta.2022.123340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2022] [Revised: 02/21/2022] [Accepted: 02/26/2022] [Indexed: 11/16/2022]
Abstract
Guanine is the most susceptible to oxidation among all the DNA bases, and 8-oxo-7,8-dihydroguanine (OG) is one of main oxidation products that can occur in any part of chromosomal DNA. OG in the telomere sequence is associated with telomere shortening, cell aging, and dysfunction, and it may induce cancers. The accurate detection of OG in telomeres is important to early clinical diagnosis and molecular research. Herein, we develop a simple and rapid method to sensitively measure 8-oxo-7,8-dihydroguanine (OG) in telomeres of cancer cells by using Bsu polymerase-mediated fluorescence coding. This method is very simple without the requirement for any nucleic acid amplification or specific restriction enzyme recognition reaction, and Bsu polymerase can selectively incorporate Cy5-dATP into the opposite site of OG, endowing this method with good specificity. Moreover, the introduction of single-molecule detection significantly improves the sensitivity. This method can detect OG within 70 min with a limit of detection (LOD) of 2.45 × 10-18 M, and it can detect OG in genomic DNA extracted from H2O2-treated HeLa cells with a LOD of 0.0094 ng, holding great potential in disease-specific gene damage research and early clinic diagnosis.

Abstract
Thymidine glycol (Tg) is the most prevalent form of oxidatively induced pyrimidine lesions in DNA. Tg can arise from direct oxidation of thymidine in DNA. In addition, 5-methyl-2'-deoxycytidine (5-mdC) can be oxidized to 5-mdC glycol, and its subsequent deamination also yields Tg. However, Tg's distribution in the human genome remains unknown. Here, we presented a DNA-protein cross-linking sequencing (DPC-Seq) method for genome-wide mapping of Tg in human cells. Our approach capitalizes on the specificity of a bifunctional DNA glycosylase, i.e., NTHL1, for the covalent labeling, as well as DPC pulldown, SDS-PAGE fractionation, and membrane transfer for highly efficient and selective enrichment of Tg-bearing DNA. By employing DPC-Seq, we detected thousands of Tg sites in the human genome, where dual ablation of NTHL1 and NEIL1, the major DNA glycosylases responsible for Tg repair, led to pronounced increases in the number of Tg peaks. In addition, Tg is depleted in genomic regions associated with active transcription but enriched at nucleosome-binding sites, especially at heterochromatin sites marked with H3K9me2. Collectively, we developed a DPC-Seq method for highly efficient enrichment of Tg-containing DNA and for genome-wide mapping of Tg in human cells. Our work offers a robust tool for future functional studies of Tg in DNA, and we envision that the method can also be adapted for mapping other modified nucleosides in genomic DNA in the future.

Abstract
Apart from the four canonical nucleobases, DNA molecules carry a number of natural modifications. Substantial evidence shows that DNA modifications can regulate diverse biological processes. Dynamic and reversible modifications of DNA are critical for cell differentiation and development. Dysregulation of DNA modifications is closely related to many human diseases. The research of DNA modifications is a rapidly expanding area and has been significantly stimulated by the innovations of analytical methods. With the recent advances in methods and techniques, a series of new DNA modifications have been discovered in the genomes of prokaryotes and eukaryotes. Deciphering the biological roles of DNA modifications depends on the sensitive detection, accurate quantification, and genome-wide mapping of modifications in genomic DNA. This review provides an overview of the recent advances in analytical methods and techniques for both the quantification and genome-wide mapping of natural DNA modifications. We discuss the principles, advantages, and limitations of these developed methods. It is anticipated that new methods and techniques will resolve the current challenges in this burgeoning research field and expedite the elucidation of the functions of DNA modifications.

Abstract
DNA damage plays a decisive role in epigenetic effects. The detection and analysis of DNA damages, like the most common change of guanine (G) to 8-oxo-7,8-dihydroguanine (OG), is a key factor in cancer research. It is especially true for G quadruplex structure (GQ), which is one of the best-known examples of a non-canonical DNA arrangement. In the present work, we provided an overview on analytical methods in connection with the detection of OG in oligonucleotides with GQ-forming capacity. Focusing on the last five years, novel electrochemical tools, like dedicated electrodes, were overviewed, as well as different optical methods (fluorometric assays, resonance light scattering or UV radiation) along with hyphenated detection and structural analysis methods (CD, NMR, melting temperature analysis and nanopore detection) were also applied for OG detection. Additionally, GQ-related computational simulations were also summarized. All these results emphasize that OG detection and the analysis of the effect of its presence in higher ordered structures like GQ is still a state-of-the-art research line with continuously increasing interest.

Abstract
The adenosine triphosphate derivatives of 2-oxo-1,3-diazaphenoxazine (dAdapTP) showed a significant discrimination ability for the template strand including that between 8-oxo-2'-deoxyguanosine (8-oxodG) and 2'-deoxyguanosine (dG) by the single nucleotide primer extension reaction using the Klenow Fragment. In this study, we synthesized new dAdapTP derivatives, i.e., 2-amino-dAdapTP, 2-chloro-dAdapTP and 2-iodo-dAdapTP, to investigate the effect on the selectivity and efficiency of incorporation for the primer extension reaction using a variety of DNA polymerases. In contrast to the previously tested dAdapTP, the selectivity and efficiency of the 2-halo-dAdapTP incorporation were dramatically decreased using the Klenow Fragment. Moreover, the efficiency of the 2-amino-dAdapTP incorporation into the T-containing template was almost the same with that of dAdapTP. In the case of the Bsu DNA polymerase, the efficiency of all the dAdapTP derivatives decreased compared to that using the Klenow Fragment. However, the incorporation selectivity of dAdapTP had improved against the oxodG-containing template for all the template sequences including the T-containing template. Moreover, 2-amino-dAdapTP showed a better efficiency than dAdapTP using the Bsu DNA polymerase. The 2-amino group of the adenosine unit may interact with syn-oxodG at the active site of the Bsu DNA polymerase during the single primer extension reaction.
