Epigenetic changes of DNA, including methylation, have long been recognized as key indicators of various diseases, including aging, cancer, and neurological disorders. Biomarker discoveries based on distinct methylation patterns for both hypermethylation and hypomethylation lead the way in discovery of novel diagnosis and treatment targets. Many different approaches are present to detect the level of methylation in whole genome (whole genome bisulfite sequencing, microarray) as well as at specific loci (methylation specific PCR). Cell-free DNA (cf-DNA) found in body fluids like blood provides information about DNA methylation and serves as a less invasive approach for genetic screening. Cell-free DNA and methylation screening technologies, when combined, have the potential to transform the way we approach genetic screening and personalized therapy. These technologies can help enhance disease diagnostic accuracy and inform the development of targeted therapeutics by providing a non-invasive way for acquiring genomic information and identifying disease-associated methylation patterns. We highlight the clinical benefits of using cell-free DNA (cf-DNA) liquid biopsy analysis and available methylation screening technologies that have been crucial in identifying biomarkers for disease from patients using a non-invasive way. Powering such biomarker discoveries are various methods of cf-DNA methylation analysis such as Bisulfite Sequencing and most recently, Methylation-Specific Restriction Enzyme (MSRE-seq) Analysis, paving the way for novel epigenetic biomarker discoveries for more robust diagnosis such as early disease detection, prognosis, monitoring of disease progression and treatment response as well as discovery of novel drug targets.

Background: Aging is a complex biological process that is associated with a decline in physiological functions and an increased risk of age-related diseases. Despite advances in molecular biology and genetics, the underlying mechanisms of aging remain largely unknown. Study: The identification of biomarkers of aging would provide a powerful tool for monitoring the effects of aging and for developing interventions to improve healthspan. Aging is associated with alterations in genetics, epigenetic marks, telomere shortening, cell senescence, and changes in the expression of genes involved in metabolism, inflammation, and DNA damage repair. Epigenetic changes, including modifications to DNA methylation and histone acetylation patterns, play a critical role in the aging process. As we age, these changes can lead to altered gene expression and contribute to the development of age-related diseases such as cancer, Alzheimer’s disease (AD) and cardiovascular disease (CVD). Conclusion: The discovery of aging biomarkers that are sensitive to these epigenetic changes has the potential to revolutionize our understanding of the aging process and inform the development of interventions to improve healthspan and extend lifespan.

Objective: To investigate the synergistic effect between rhein(RHE) and oxacillin against Staphylococcus aureus(MRSA) at the gene level. Method: A minimum inhibitory concentration and checkerboard dilution test were conducted to evaluate antibacterial activity. Reverse transcriptase polymerase chain reaction was conducted to investigate the gene expressions. Results: RHE exhibited a minimum inhibitory concentration of 62.5-250.0 μg/mL against various MRSA strains and the reference strain, respectively. As revealed by the checkerboard assay, a combination of RHE and oxacillin exhibited synergistic or partially synergistic effects against MRSA strains. RHE decreased the expressions of mecA/blaZ in a dose-dependent manner. RHE also decreased the expressions of the regulator genes mecI/blaI and mecR1/blaR1. Conclusions: We suggest that RHE affects the activity of mecR1/blaR1, which is located in the cell membrane of MRSA and results in the suppression of mecA/mecI/mecR1 and blaZ/blaI/blaR1 gene expressions.

OBJECTIVE: To quantitatively evaluate the therapeutic effects of Red Liriope platyphylla(RLP) on atopic dermatitis(AD), alterations in the luciferase(Luc) signal and general phenotype biomarkers were compared in phthalic anhydride(PA) treated Interleukin-4(IL-4)/Luc/Consensus non-coding sequence-1(CNS-1) transgenic(Tg) mice following treatment with aqueous extract of RLP(AEt RLP) for4 ***: Alterations in AD phenotypes were measured in IL-4/Luc/CNS-1 Tg mice following treatment with AEt RLP using inflammation parameter analysis, bioluminescence imaging analysis, histological analysis, reverse transcription-polymerase chain reaction, enzyme linked immunosorbent assay and Western blot ***: RLP contained high concentrations of total phenolic compounds, total flavonoid compounds and 5-HNE related to AD therapy. The Luc signal was only detected in the abdominal region and the submandibular lymph node(SL), mesenteric lymph node(ML), thymus and pancreas of the PA treated group. This signal was significantly decreased by 28%-73% throughout the body and in the four organs in PA + AEt RLP treated group. Furthermore, the lymph node weight, immunoglobulin E concentration and dermal thickness were decreased by 37%-67% in the PA + AEt RLP treated ***: Our findings suggest that the therapeutic effect of AEt RLP on PA induced AD could be successfully quantified by comparison of Luc signals and AD phenotype markers in IL-4/Luc/CNS-1Tg mice, and that the Luc signal was as sensitive as the general AD phenotypes, enabling detection of effects without euthanasia.

Slow speed of the Next-Generation sequencing data analysis, compared to the latest high throughput sequencers such as HiSeq X system, using the current industry standard genome analysis pipeline, has been the major factor of data backlog which limits the real-time use of genomic data for precision medicine. This study demonstrates the DRAGEN Bio-IT Processor as a potential candidate to remove the “Big Data Bottleneck”. DRAGENTM accomplished the variant calling, for ~40× coverage WGS data in as low as ~30 minutes using a single command, achieving the over 50-fold data analysis speed while maintaining the similar or better variant calling accuracy than the standard GATK Best Practices workflow. This systematic comparison provides the faster and efficient NGS data analysis alternative to NGS-based healthcare industries and research institutes to meet the requirement for precision medicine based healthcare.
