Abstract
Environmental exposure would cause DNA damage and epigenetic modification changes, potentially resulting in physiological dysfunction, thereby triggering diseases and even cancer. DNA damage and epigenetic modifications are thus promising biomarkers for environmental exposures and disease states. Benefiting from its high sensitivity and accuracy, high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) is considered the "gold standard technique" for investigating epigenetic DNA modifications. This review summarizes the recent advancements of UHPLC-MS/MS-based technologies for DNA damage and epigenetic modifications analysis, mainly focusing on the innovative methods developed for UHPLC-MS/MS-related pretreatment technologies containing efficient genomic DNA digestion and effective removal of the inorganic salt matrix, and the new strategies for improving detection sensitivity of liquid chromatography-mass spectrometry. Moreover, we also summarized the novel hyphenated techniques of the advanced UHPLC-MS/MS coupled with other separation and analysis methods for the measurement of DNA damage and epigenetic modification changes in special regions and fragments of chromosomes.

Abstract
Gel electrophoresis is a powerful technique for the characterization of sequences, sizes and conformations of nucleic acids due to its remarkable separation efficiency. In parallel, liquid chromatography-mass spectrometry (LC-MS) has established itself as a staple tool for the meticulous characterization and accurate quantification of a multitude of DNA modifications. In this study, we devised an in-gel digestion method for coupling gel electrophoresis with LC-MS/MS. This process involves the enzymatic digestion of DNA within the gel by nucleases and release single nucleosides, which subsequently serve as a preprocessing step for (LC-MS/MS) analysis. We demonstrated that ethylenediaminetetraacetic acid (EDTA) in the routine gel electrophoresis buffer reduced the enzymatic digestion efficiency, while Mg2+ could mitigate this inhibition. We further showed EDTA-free gel electrophoresis and the process of digestion of genomic DNA and plasmid DNA within a gel was fluorescently imaged, proving the efficient digestion of DNA. By this improvement, the efficiency of an in-gel digestion could reach 60% or more of the control, compared with direct in-solution digestion. The measured abundances of DNA modifications (5-methylcytosine and N6-methyladenine) via in-gel digestion are consistent with that measured by in-solution digestion. Collectively, we showed an in-gel digestion method, which is a very useful pretreatment technique for the precise quantification of epigenetic modifications in diverse DNA molecules.

Abstract
N6-Methyladenosine (m6A) is one of the most abundant and prevalent natural modifications occurring in diverse RNA species. m6A plays a wide range of roles in physiological and pathological processes. Revealing the functions of m6A relies on the faithful detection of individual m6A sites in RNA. However, developing a simple method for the single-base resolution detection of m6A is still a challenging task. Herein, we report an adenosine deamination sequencing (AD-seq) technique for the facile detection of m6A in RNA at single-base resolution. The AD-seq approach capitalizes on the selective deamination of adenosine, but not m6A, by the evolved tRNA adenosine deaminase (TadA) variant of TadA8e or the dimer protein of TadA-TadA8e. In AD-seq, adenosine is deaminated by TadA8e or TadA-TadA8e to form inosine, which pairs with cytidine and is read as guanosine in sequencing. m6A resists deamination due to the interference of the methyl group at the N6 position of adenosine. Thus, the m6A base pairs with thymine and is still read as adenosine in sequencing. The differential readouts from A and m6A in sequencing can achieve the single-base resolution detection of m6A in RNA. Application of the proposed AD-seq successfully identified individual m6A sites in Escherichia coli 23S rRNA. Taken together, the proposed AD-seq allows simple and cost-effective detection of m6A at single-base resolution in RNA, which provides a valuable tool to decipher the functions of m6A in RNA.

Abstract
Chemical modifications in DNA have profound influences on the structures and functions of DNA. Uracil, a naturally occurring DNA modification, can originate from the deamination of cytosine or arise from misincorporation of dUTP into DNA during DNA replication. Uracil in DNA will imperil genomic stability due to their potential in producing detrimental mutations. An in-depth understanding of the functions of uracil modification requires the accurate determination of its site as well as content in genomes. Herein, we characterized that a new member of the uracil-DNA glycosylase (UDG) family enzyme (UdgX-H109S) could selectively cleave both uracil-containing single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA). Based on this unique property of UdgX-H109S, we developed an enzymatic cleavage-mediated extension stalling (ECES) method for the locus-specific detection and quantification of uracil in genomic DNA. In the ECES method, UdgX-H109S specifically recognizes and cleaves the N-glycosidic bond of uracil from dsDNA and generates an apurinic/apyrimidinic (AP) site, which could be broken by APE1 to form a one-nucleotide gap. The specific cleavage by UdgX-H109S is then evaluated and quantified by qPCR. With the developed ECES approach, we demonstrated that the level of uracil at position Chr4:50566961 in genomic DNA of breast cancer tissues was significantly decreased. Collectively, the ECES method has been proved to be accurate and reproducible in the locus-specific quantification of uracil in genomic DNA from biological and clinical samples.

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
RNA molecules contain diverse modifications that play crucial roles in a wide variety of biological processes. Inosine is one of the most prevalent modifications in RNA and dysregulation of inosine is correlated with many human diseases. Herein, we established an acrylonitrile labeling-mediated elongation stalling (ALES) method for quantitative and site-specific detection of inosine in RNA from biological samples. In ALES method, inosine is selectively cyanoethylated with acrylonitrile to form N1-cyanoethylinosine (ce1I) through a Michael addition reaction. The N1-cyanoethyl group of ce1I compromises the hydrogen bond between ce1I and other nucleobases, leading to the stalling of reverse transcription at original inosine site. This specific property of stalling at inosine site could be evaluated by subsequent real-time quantitative PCR (qPCR). With the proposed ALES method, we found the significantly increased level of inosine at position Chr1:63117284 of Ino80dos RNA of multiple tissues from sleep-deprived mice compared to the control mice. This is the first report on the investigation of inosine modification in sleep-deprived mice, which may open up new direction for deciphering insomnia from RNA modifications. In addition, we found the decreased level of inosine at GluA2 Q/R site (Chr4:157336723) in glioma tissues, indicating the decreased level of inosine at GluA2 Q/R site may serve as potential indicator for the diagnosis of glioma. Taken together, the proposed ALES method is capable of quantitative and site-specific detection of inosine in RNA, which provides a valuable tool to uncover the functions of inosine in human diseases.

Abstract
RNA molecules contain diverse modifications that play crucial roles in a wide variety of biological processes. Adenosine-to-inosine (A-to-Ino) RNA editing is one of the most prevalent modifications among all types of RNA. Abnormal A-to-InoRNA editing has been demonstrated to be associated with many human diseases. Identification of A-to-Ino editing sites is indispensable to deciphering their biological roles. Herein, by employing the unique property of human endonuclease V (hEndoV), we proposed a hEndoV-mediated sequencing (hEndoV-seq) method for the single-base resolution detection of A-to-InoRNA editing sites. In this approach, the terminal 3'OH of RNA is first blocked by 3'-deoxyadenosine (3'-deoxy-A). Specific cleavage of Ino sites by hEndoV protein produces new terminal 3'OH, which can be identified by sequencing analysis, and therefore offers the site-specific detection of Ino in RNA. The principle of hEndoV-seq is straightforward and the analytical procedure is simple. No chemical reaction is involved in the sequencing library preparation. The whole procedure in hEndoV-seq is carried out under mild conditions and RNA is not prone to degradation. Taken together, the proposed hEndoV-seq method is capable of site-specific identification of A-to-Ino editing in RNA, which provides a valuable tool for elucidating the functions of A-to-Ino editing in RNA.

Abstract
Fish and other seafood products are essential dietary components that are highly appreciated and consumed worldwide. However, the high perishability of these products has driven the development of a wide range of processing, preservation, and analytical techniques. This development has been accelerated in recent years with the advent of the fourth industrial revolution (Industry 4.0) technologies, digitally transforming almost every industry, including the food and seafood industry. The purpose of this review paper is to provide an updated overview of recent thermal and nonthermal processing and preservation technologies, as well as advanced analytical techniques used in the seafood industry. A special focus will be given to the role of different Industry 4.0 technologies to achieve smart seafood manufacturing, with high automation and digitalization. The literature discussed in this work showed that emerging technologies (e.g., ohmic heating, pulsed electric field, high pressure processing, nanotechnology, advanced mass spectrometry and spectroscopic techniques, and hyperspectral imaging sensors) are key elements in industrial revolutions not only in the seafood industry but also in all food industry sectors. More research is still needed to explore how to harness the Industry 4.0 innovations in order to achieve a green transition toward more profitable and sustainable food production systems.
