Abstract
Gastric cancer (GC) is a significant source of global cancer death with a high mortality rate, because the majority of patients with GC are diagnosed at a late stage, with limited therapeutic choices and poor outcomes. Therefore, development of minimally invasive or noninvasive biomarkers which are specific to GC is crucially needed. The latest advancements in the understanding of GC molecular landscapes and molecular biological methods have accelerated attempts to diagnose GC at an early stage. Body fluids, including peripheral blood, saliva, gastric juice/wash, urine, and others, can be a source of biomarkers, offering new methods for the early detection of GC. Liquid biopsy-based methods using circulating sources of cancer nucleic acids could also be considered as alternative strategies. Moreover, investigating gastric juices/washes could represent an alternative for the detection of GC via invasive biopsy. This review summarizes recently reported biomarkers based on DNA methylation, microRNA, long noncoding RNA, circular RNA, or extracellular vesicles (exosomes) for the detection of GC. Although the majority of studies have been conducted to detect these alterations in advanced-stage GC and only a few in population studies or early-stage GC, some biomarkers are potentially valuable for the development of novel approaches for an early noninvasive detection of GC.

Cancer-related genetic variants of Helicobacter pylori strains determined using gastric wash-based whole-genome analysis with single-molecule real-time technology. Int J Cancer 2020; 148:178-192. [PMID: 32803883 DOI: 10.1002/ijc.33257] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Revised: 06/22/2020] [Accepted: 08/04/2020] [Indexed: 12/17/2022]
Abstract
Helicobacter pylori (H. pylori) are a primary factor in the pathogenesis of gastric cancer (GC); GC ranks third among cancer-related mortality. A clear understanding of the H. pylori genome factors underlying GC is necessary to develop more effective methods to prevent GC. A single-molecule real-time DNA sequencing-based H. pylori genome-wide association study analysis was performed using the H. pylori genome present in five early-stage GC (EGC) and five non-GC clinical DNA samples recovered from gastric washes. A total of 275 genes with 702 nucleotide variants (NVs) were found to be common to three or more patients with EGC but no non-GC patients (single-NV: 654/702, 93.2%; multi-NV: 40/702, 5.7%; deletion: 3/702, 0.4%; insertion: 3/702, 0.7%). Gene ontology analysis of H. pylori revealed that genes involved in the mitochondrial electron transport system, glycolytic processes and the TCA cycle were highly enriched. Cancer-related NVs were most frequently found in a member of the Helicobacter outer membrane protein family, hopL. In particular, one of the NVs in hopL was a novel six-nucleotide insertion (1159095̂1159096, TACTTC); this mutant was detected more frequently in a validation set of 50 additional EGC samples (22/50, 44.0%) than in 18 non-GC samples (3/18, 16.7%, P = .04). These results suggest that the hopL variant is associated with the development of GC and may serve as a genetic biomarker of H. pylori virulence and GC risk. Our assay can serve as a potent tool to expand our understanding of bacteria-associated tumorigenesis.

Mouthwash-Based Highly Sensitive Pyro-Genotyping for Nine Sexually Transmitted Human Papilloma Virus Genotypes. Int J Mol Sci 2020; 21:ijms21103697.

Abstract
Human papillomavirus (HPV) is a common sexually transmitted infection worldwide, which spreads via contact with infected genital, anal, and oral/pharyngeal areas (oral sex) owing to diverse manners of sexual intercourse. In this study, we devised an oral HPV detection method using mouthwash waste fluids that causes less psychological resistance to visiting the outpatient otolaryngology departments. We successfully detected only the specific unique reverse sequencing probe (using pyro-genotyping) and identified the nine genotypes of HPV targeted for vaccination by pyrosequencing the mouthwash waste fluids of non-head and neck cancer patient volunteers (n = 52). A relatively large number (11/52) of mouthwash waste fluids tested positive for HPV (21.2%; genotype 6, n = 1; 11, n = 1; 16, n = 1; and 18, n = 8). These results surpassed the sensitivity observed testing the same specimens using the conventional method (1/52, 1.9%). Our method (pyro-genotyping) was developed using nine HPV genotypes targeted for vaccination and the results were highly sensitive compared to those of the conventional method. This less expensive, high-throughput, and simple method can be used for detecting oral HPV infection with fewer socio-psychological barriers.

Abstract
BACKGROUND Treatment of Helicobacter pylori infection is often empiric; however, current guidelines for management of Helicobacter pylori infection advise against the use of standard triple therapy (clarithromycin, amoxicillin, and proton-pump inhibitor) when clarithromycin resistance exceeds 20%. We developed and tested a new culture-free assay to detect clarithromycin resistance-conferring mutations to determine the prevalence of H. pylori clarithromycin resistance in patients from the United States Pacific Northwest. MATERIALS AND METHODS Droplet digital PCR (ddPCR) was used to detect the H. pylori 23S rRNA gene, and resistance-conferring mutations, in archived, formalin-fixed, paraffin-embedded (FFPE) gastric tissue and to retrospectively determine the prevalence of clarithromycin-resistant H. pylori among 110 patients at an academic medical center in the Northwest United States between 2012 and 2014. RESULTS Of 102 patients with the H. pylori 23S rRNA gene detected by the ddPCR assay, 45 (44%) had clarithromycin resistance mutations. Thirty-three of the 45 patients with clarithromycin resistance mutations had a mix of wild-type and resistance alleles. Prevalence of clarithromycin resistance mutations differed among racial groups and was highest among Asians, with mutations detected in 14 (67%) of the 21 patient samples. CONCLUSIONS The prevalence of clarithromycin resistance detected in this region exceeds 20%, indicating that standard triple therapy should not be the first-line antibiotic treatment for H. pylori infection. Culture-free assays for detecting clarithromycin resistance mutations can be performed on archived tissue samples and will aid in informing tailored treatment for effective H. pylori eradication.
