Abstract
All-in-one treatments represent a paradigm shift in future medicine. For example, inflammatory bowel disease (IBD) is mainly diagnosed by endoscopy, which could be applied for not only on-site monitoring but also the intestinal lesion-targeted spray of injectable hydrogels. Furthermore, molecular conjugation to the hydrogels would program both lesion-specific adhesion and drug-free therapy. This study validated this concept of all-in-one treatment by first utilizing a well-known injectable hydrogel that underwent efficient solution-to-gel transition and nanomicelle formation as a translatable component. These properties enabled spraying of the hydrogel onto the intestinal walls during endoscopy. Next, peptide conjugation to the hydrogel guided endoscopic monitoring of IBD progress upon adhesive gelation with subsequent moisturization of inflammatory lesions, specifically by nanomicelles. The peptide was designed to mimic the major component that mediates intestinal interaction with Bacillus subtilis flagellin during IBD initiation. Hence, the peptide-guided efficient adhesion of the hydrogel nanomicelles onto Toll-like receptor 5 (TLR5) as the main target of flagellin binding and Notch-1. The peptide binding potently suppressed inflammatory signaling without drug loading, where TLR5 and Notch-1 operated collaboratively through downstream actions of tumor necrosis factor-alpha. The results were produced using a human colorectal cell line, clinical IBD patient cells, gut-on-a-chip, a mouse IBD model, and pig experiments to validate the translational utility. Injectable nanomicelle hydrogel for all-in-one treatment of intestinal inflammation. Spraying of the hydrogel onto the intestinal walls during endoscopy.

Abstract
Cells secrete extracellular vesicles (EVs) carrying cell-of-origin markers to communicate with surrounding cells. EVs regulate physiological processes ranging from intercellular signaling to waste management. However, when senescent cells (SnCs) secrete EVs, the EVs, which are newly regarded as senescence-associated secretory phenotype (SASP) factors, can evoke inflammation, senescence induction, and metabolic disorders in neighboring cells. Unlike other soluble SASP factors, the biophysical properties of EVs, including small EVs (sEVs), derived from SnCs have not yet been investigated. In this study, sEVs were extracted from a human IMR90 lung fibroblast in vitro senescence model. Their biomechanical properties were mapped using atomic force microscopy-based quantitative nanomechanical techniques, surface potential microscopy, and Raman spectroscopy. The surfaces of sEVs derived from SnCs are slightly stiffer but their cores are softer than those of sEVs secreted from non-senescent cells (non-SnCs). This inversely proportional relationship between deformation and stiffness, attributed to a decrease in the concentration of genetic and protein materials inside the vesicles and the adsorption of positively charged SASP factors onto the vesicle surfaces, respectively, was found to be a peculiar characteristic of SnC-derived sEVs. Our results demonstrate that the biomechanical properties of SnC-derived sEVs differ from those of non-SnC-derived sEVs and provide insight into the mechanisms underlying their formation and composition.

Abstract
Abstract
Glioblastoma (GBM) is the most common and aggressive primary brain cancer in adults. Although multiple oncogenic mutations have been identified in neural stem cells of the subventricular zone (SVZ) in humans, the dynamic process of how tumor initiation begins with a mutation-harboring stem cells remains elusive. To better understand how GBM evolves, we analyzed longitudinal transcriptomic changes of mutation-harboring stem cells using a spontaneous, somatic GBM animal model with EGFRvIII, TP53, PTEN mutations. Using single-cell RNA sequencing, we have identified precancerous cell populations originating from oligodendrocyte precursor cells, with increased proliferation and decreased capacity to differentiate into oligodendrocytes. The precancerous cell populations undergo malignant transformation to become heterogeneous cancer cells characterized by immune evasion, mesenchymal transition, and cell cycle. We further identified the precancerous populations in the SVZ of human GBM patients with chromosomal aberrations. Our findings suggest that GBM evolution is closely related to oligodendrocyte precursor cell specification, and the time-dependent transcriptomic changes in precancerous cells is a novel therapeutic target for tumor evolution.

Abstract
Abstract
Neural stem cells (NSCs) harboring cancer-driving mutations in the subventricular zone (SVZ) have recently been reported as the cells of origin for human GBM. However, the pathological role of residual tumor-initiating NSCs (tNSCs) in the SVZ is undetermined for recurrent tumors after surgical removal of the primary tumor. After the primary resection of GBM, most recurrences still appear as local tumors around the resection cavity (RC). Accordingly, after surgical removal, we hypothesized that the tNSCs in SVZ might be the source for tumor construction at RC as local recurrence. Here, we examined the role of tNSCs in developing local tumors around RC using a mouse model and human tissues. First, cancer-driving mutations, including Trp53, Pten, and Egfr mutations, were introduced to NSCs in SVZ through in vivo electroporation, and the RC was generated in the remote cortex through surgical resection. We found that the NSCs harboring driver mutations migrated specifically to the RC through the aberrant growth of oligodendrocyte-precursor cells (OPCs). Furthermore, the SVZ-originated cells constituted the GBM around the RC at four weeks post-resection in 64% of mouse models. Second, the CXCR4/CXCL12 axis was upregulated through migration from the SVZ and tumor formation at the RC compared with primary tumors without the RC. Blockage of the CXCR4/CXCL12 axis decreased the number of immigrating OPC lineage and switched the differentiation of tNSC to astrocyte lineage. Furthermore, it improved survival rates in vivo. Third, we validated the independent clonal evolution of recurrent tumor from SVZ and the upregulation of CXCR4 axis in the recurrent tumor in a human patient. Taken together, our results reveal that the residual tNCSs harboring cancer-driving mutations in the SVZ can re-construct tumors after surgical resection of GBM. Blocking CXCL12/CXCR4 might be a potential treatment strategy for preventing recurrences after resection.

Abstract
Human glioblastoma (GBM), originating from the subventricular zone (SVZ), occurs due to molecular disruptions in chromosomes. Most GBM tissues exhibit definitive chromosomal patterns: copy-number-variations (CNV) in chromosome 7 (gain) and 10 (loss), known as the earliest molecular events. Herein, we hypothesised that the origin-cells in SVZ of GBM patients can provide clues regarding these chromosomal alterations. We compared bulk RNA sequencing (RNAseq) data of GBM tumor tissue (n=126), tumour free GBM SVZ (n=40), and tumor-free control SVZ of non-glial tumor (n=9). Paired single-cell-level RNAseq samples of tumor free GBM SVZ (n=7) and GBM tumor tissue (n=10), were done to see cell specific CNVs. Using human SVZ and GBM samples as a background, we generated origin-cell and origin-cell-derived tumour cell using CRISPR/Cas9. In this work, we identified two GBM-origin-cell types with stem-cell signatures during single-cell level analyses of 60 SVZ tissue samples obtained from tumor-free regions of GBM patients. Furthermore, single-cell level analysis revealed that two origin-cell types in SVZ harbor ongoing patterns of CNV alterations. Among the origin-cells found in the SVZ of GBM patients, NO-like cells showed neural progenitor plus oligodendrocyte progenitor (NO) signature, while AN-like cells showed astrocyte plus neural stem cell (AN) signature. For the interconnectedness, we subjected single-cell-level RNA-seq data to ligand-receptor connection analysis. In the stem cell mode, NO-like cells was connected to AN-like cells in SVZ samples and while in the tumor samples, cycling cell was connected to AN-like cells. NO-like cells was common in TERT promoter wildtype GBM and AN-like cells was more common in TERT promoter mutant GBM. CRISPR/Cas9 models revealed accumulation copy-number alterations from non-tumorigenic origin-cells to tumor cells. These two origin-cells (NO-like cells and AN-like cells) derived from the SVZ of the adult human brain will facilitate the understanding of GBM genesis and development of potential novel therapeutic targets.

Abstract
The human gut-on-a-chip has demonstrated in vivo-relevant cellular fidelity and physiological functions of Caco-2 intestinal epithelium compared to its static cultures. However, transcriptomic dynamics that controls the morphogenic and mechanodynamic perturbation of Caco-2 epithelium in a microphysiological culture remain elusive. Single-cell transcriptomic analysis revealed that a gut-on-a-chip culture drives three clusters that illustrate distinct gene expressions and their spatial representation in three-dimensional (3D) epithelial layers. A pseudotemporal trajectory analysis elucidated the evolutionary transition from a homogeneous ancestral genotype in Transwell cultures into heterogeneous transcriptomes in gut-on-a-chip cultures, verified in cell cycle perturbation, cytodifferentiation, and intestinal functions in digestion, transport, and drug metabolism. Furthermore, the inversed transcriptomic signature of oncogenes and tumor-suppressor genes of Caco-2 cells confirmed that gut-on-a-chip cultures induce post-mitotic reprogramming of cancer-associated genes. Our study suggests that a physiological gut-on-a-chip culture induces the transcriptomic perturbation of Caco-2 epithelium to elicit in vivo-relevant morphogenesis and restoration of normal physiological functions. Gut-on-a-chip cultures induce the mechanodynamic stimulation of Caco-2 epithelium Single-cell transcriptomics confirms spatial mapping of reprogrammed Caco-2 cells Pseudotemporal evolution of Caco-2 perturbs intestinal functions and drug metabolism Microphysiological on-chip cultures reprogram cancer inheritance of Caco-2 cells

Abstract
The present study was conducted to determine the occurrence of B. cereus group members in low-moisture food products by phenotypic and genetic assessment and to evaluate the toxigenic potential of B. cereus group isolates. According to the results of their morphological shape, growth temperature range, strain-specific gene distribution, 79.5% and 20.5% among 112 isolates were identified as B. cereus sensu stricto (s.s.) and B. thuringiensis, respectively and other toxigenic B. cereus group members was not found. All B. cereus group isolates possessed nheABC, hblACD, cytK, entFM genes, and the most frequent gene was nheA. Only three B. cereus s. s. isolates exhibited as emetic toxin gene-harboring B. cereus group. Several B. cereus s.s. and B. thuringiensis isolates from a low-moisture food products were moderate biofilm formers and showed resistance to rifampicin, tetracycline, or clindamycin. The existence of B. cereus s.s. and B. thuringiensis in low-moisture food products indicates the possible risk of foodborne infections due to their virulence potential.

Abstract
Thyroid cancer is associated with genetic alterations, e.g. BRAFV600E , which may cause carcinomatous changes in hormone-secreting epithelial cells. Epidemiological studies have shown that overnutrition is related to the development and progression of cancer. In this study, we attempted to identify the cell nonautonomous factor responsible for the progression of BRAFV600E thyroid cancer under overnutrition conditions. We developed a mouse model for inducible thyrocyte-specific activation of BRAFV600E , which showed features similar to those of human papillary thyroid cancer. LSL-BrafV600E ;TgCreERT2 showed thyroid tumour development in the entire thyroid, and the tumour showed more abnormal cellular features with mitochondrial abnormalities in mice fed a high-fat diet (HFD). Transcriptomics revealed that adrenomedullin2 (Adm2) was increased in LSL-BrafV600E ;TgCreERT2 mice fed HFD. ADM2 was upregulated on the addition of a mitochondrial complex I inhibitor or palmitic acid with integrated stress response (ISR) in cancer cells. ADM2 stimulated protein kinase A and extracellular signal-regulated kinase in vitro. The knockdown of ADM2 suppressed the proliferation and migration of thyroid cancer cells. We searched The Cancer Genome Atlas and Genotype-Tissue Expression databases and found that increased ADM2 expression was associated with ISR and poor overall survival. Consistently, upregulated ADM2 expression in tumour cells and circulating ADM2 molecules were associated with aggressive clinicopathological parameters, including body mass index, in thyroid cancer patients. Collectively, we identified that ADM2 is released from cancer cells under mitochondrial stress resulting from overnutrition and acts as a secretory factor determining the progressive properties of thyroid cancer. © 2022 The Authors.

Abstract
Abstract
Background
Even though the presence of hyperglycemia has shown to affect the clinical outcome of cardiogenic shock patients, the extent of hyperglycemia and its association with prognosis have not been fully addressed in large population
Purpose
Investigate the clinical relationship between hyperglycemic status and in-hospital mortality in cardiogenic shock patients
Method
A total of 1,177 consecutive cardiogenic shock patients were enrolled from January 2014 to December of 2018 at 12 hospitals in South Korea. The primary outcome was in-hospital mortality. Patients were divided into four groups according to their initial plasma glucose level in each of diabetes patients (n=752) and non-diabetes patients (n=425); group 1 (≤8 mmol/L), group 2 (8–12 mmol/L), group 3 (12–16 mmol/L) and group 4 (≥16 mmol/L).
Results
The groups with higher admission plasma glucose were associated with lower systolic blood pressure and higher lactic acid level in both diabetic and non-diabetic patients. In-hospital mortality increased in groups with higher admission plasma glucose level in non-diabetic patients (group-1:24.2%, group-2: 28.6%, group-3: 38.1%, group-4: 49.0%, p<0.01) whereas in diabetic patients, mortality and admission plasma glucose level showed no significant association (group-1: 45%, group-2: 35.4%, group-3: 33.3%, group-4: 43.1%, p=0.26). Even after Multivariate analysis, high plasma glucose was an independent predictor of in-hospital mortality in non-diabetic patients
Conclusion
In cardiogenic shock patients, plasma glucose obtained at admission was associated with in-hospital mortality in non-diabetic patients

Abstract
Abstract
Background
In a few studies, obesity was associated with better outcomes in patients with cardiogenic shock (CS). Although this phenomenon, the “obesity paradox”, reportedly manifests differently based on sex in other disease entities, it has not yet been investigated in CS patients.
Methods and results
1,227 patients with CS from The REtrospective and prospective observational Study to investigate Clinical oUtcomes and Efficacy of left ventricular assist device for Korean patients with cardiogenic shock (RESCUE) registry in Korea were analyzed. The study population was classified into obese and non-obese groups according to Asian-Pacific criteria (BMI >25.0 kg/m2 for obese). Clinical impact of obesity on in-hospital mortality according to sex was analyzed using logistic regression analysis and restricted cubic spline curves. In-hospital mortality rate was significantly lower in obese men than non-obese men (34.2% vs. 24.1%, p=0.004) while the difference was not significant in women (37.3% vs. 35.8%, p=0.884). As a continuous variable, higher BMI showed a protective effect in men conversely, BMI was not associated with clinical outcomes in women. Comparing to normal-weight patients, obesity was associated with a decreased risk of in-hospital death in men (multivariable-adjusted OR 0.63, CI 0.43–0.92, p=0.016), not in women (multivariable-adjusted OR 0.94, 95% CI 0.55–1.61, p=0.828). Interaction P value for the association between BMI and sex was 0.023.
Conclusions
Obesity paradox exists and apparently occurs in men among CS patients. The differential effect of BMI on in-hospital mortality was observed according to sex.

Abstract
Inflammatory bowel disease (IBD) is a chronic and recurrent illness of the gastrointestinal tract. Treatment of IBD traditionally involves the use of aminosalicylic acid and steroids, while these drugs has been associated with untoward effects and refractoriness. The absence of effective treatment regimen against IBD has led to the exploration of new targets. Parasites are promising as an alternative therapy for IBD. Recent studies have highlighted the use of parasite-derived substances, such as excretory secretory products, extracellular vesicles (EVs), and exosomes, for the treatment of IBD. In this report, we examined whether EVs secreted by Giardia lamblia could prevent colitis in a mouse model. G. lamblia EVs (GlEVs) were prepared from in vitro cultures of Giardia trophozoites. Clinical signs, microscopic colon tissue inflammation, and cytokine expression levels were detected to assess the effect of GlEV treatment on dextran sulfate sodium (DSS)-induced experimental murine colitis. The administration of GlEVs prior to DSS challenge reduced the expression levels of pro-inflammatory cytokines, including tumor necrosis factor alpha, interleukin 1 beta, and interferon gamma. Our results indicate that GlEV can exert preventive effects and possess therapeutic properties against DSS-induced colitis.

Abstract
While dialysis is linked with prurigo nodularis, little is known about the impact of non-dialysis chronic kidney disease on prurigo nodularis. The influence of chronic kidney disease on development of prurigo nodularis was measured using the Korean National Health Insurance and National Health Screening Program data, identifying 17,295,576 individuals without prior prurigo nodularis. Chronic kidney disease severity was determined by the estimated glomerular filtration rate (in ml/min/1.73 m2) calculated from serum creatinine, and proteinuria detected with urine dipstick. Prurigo nodularis incidence during follow-up was determined. Over a median follow-up period of 9.72 years, 58,599 individuals developed prurigo nodularis, with an incidence rate of 3.59 per 10,000 person-years. Among different variables, estimated glomerular filtration rate was the strongest risk factor for prurigo nodularis. Compared with estimated glomerular filtration rate ≥ 90, estimated glomerular filtration rate 15–29 (hazard ratio 1.31, 95% confidence interval 1.05–1.62) and end-stage renal disease (hazard ratio 1.46, 95% confidence interval 1.25–1.69) were associated with higher risks. The presence of proteinuria independently increased the risk of prurigo nodularis, increased risks associated with estimated glomerular filtration rate 15–29 and endstage renal disease, and caused risk associated with estimated glomerular filtration rate 30–59 to become significant. With differential impact of chronic kidney disease severity on the risk of prurigo nodularis, preservation of renal function would potentially translate into lower risk of prurigo nodularis.

Abstract
Background There are no guidelines for straightforwardly managing advanced lung cancer (T3 or T4). Although surgery has traditionally been regarded as the mainstay treatment and the only curative modality, it has limited relevance for patients with locally advanced non-small cell lung cancer (NSCLC). Photodynamic therapy (PDT) is a clinically approved cancer therapy; it is an established treatment modality with curative intent for early-stage and superficial endobronchial lesions. However, the efficacy of PDT in advanced lung cancer is controversial, and it has primarily been used in palliative care. Case presentation This case report describes a 70-year-old male who had right upper lung cancer and an endobronchial lesion that extended into the distal trachea. A biopsy specimen was obtained upon bronchoscopy, and the result confirmed squamous cell carcinoma. We performed a definitive sleeve lobectomy and intraoperative PDT. Gross total resection of the tumor was achieved, but the presence of microscopic residual tumors was inevitable. Complete anatomical resection of the primary tumor by pneumonectomy was not possible due to poor lung function and endobronchial extension to the distal trachea. We decided to apply intraoperative PDT to the lumen and outer wall of the bronchi and distal trachea for local tumor control. The patient is alive with no evidence of disease after 13 months of follow-up. Conclusions This is the first report to describe the feasibility and efficacy of intraoperative PDT as part of multimodal therapy for locally advanced NSCLC.

Abstract
BACKGROUND AND OBJECTIVES The junctional epithelium (JE) has been recognized as a defensive organ rich in polymorphonuclear leukocytes (PMNs). However, the migration of PMNs through the JE has not been clearly documented. For mucosal defense, PMNs migrate outwards over the epithelium to defend the intestinal or respiratory tract on the epithelial surface. With this background, the present study investigated whether there is any structural evidence showing the transepithelial migration of PMNs through the JE in gingival mucosa. METHODS Three-dimensional modeling of gingiva surrounding mouse molars at varying ages was performed by array tomography. Images of the serial sections for array tomography at the 800 nm thickness were obtained using back scattered electron (BSE) detector equipped in the field-emission scanning electron microscopy (FESEM). Expressions of neutrophil marker or CD47 were immunohistochemically examined on the frozen sections. RESULTS Array tomography using FESEM and 3-dimensional modeling clearly showed that a system of epithelial channels developed between keratinocytes and generally ran along the long axis of the JE. Most PMNs were found inside the channels, rather than being scattered throughout the JE. The channels could be traced from the base of the JE to the bottom of the gingival sulcus, although some channels were fragmented and interrupted with short intercellular gaps. CONCLUSIONS These findings suggest that the JE may be an organ for transepithelial migration of PMNs to the bottom of the gingival sulcus through epithelial channels, as occurs in the epithelial lining of other organs such as the intestinal or respiratory tract.

Abstract
Caregivers of persons with dementia (PWDs) were socially isolated with little support during the COVID-19 pandemic "Stay-At-Home" order in the United States. To enhance social and emotional connection for diverse caregivers, a culturally/linguistically appropriate telephone intervention provided compassionate listening, mindful breathing, and COVID-19 safety education. The study purpose was to understand caregiving challenges and to evaluate the intervention for caregivers during the early pandemic using a qualitative approach. Twenty-three caregivers participated in the intervention provided by bilingual research assistants for 3 months. Call logs were used to describe the caregivers' dialogue. Thematic analysis identified (a) the challenges, including fear of coronavirus disease, providing around-the-clock care, and forced isolation and negative emotions; and (b) caregivers' experience with the intervention, including connecting with the outside, relief from emotional stress, reliable COVID-19 information, and reinformed caregiving skills. Results suggest that the telephone support was of benefit to diverse caregivers of PWDs during the pandemic by promoting social connection and reducing emotional distress.

Abstract
OBJECTIVE We aimed to explore the impact of sarcopenia on the cortical thickness, white matter hyperintensity (WMH), and subcortical volumes in the cognitively normal older adults. METHODS Sixty cognitively normal older adults with and without sarcopenia were enrolled in the study. They underwent T1 and FLAIR magnetic resonance imaging. Information on muscle mass, muscle strength and muscle function were measured using bioelectrical impedance analysis, handgrip strength and 5 time-chair stand test (CST) respectively. Structural magnetic resonance images were analyzed and processed using Freesurfer v6.0. RESULTS Compared to the control group, the sarcopenia group demonstrated reduced cortical thickness in left superior frontal, precentral, right post central, inferior parietal, rostral middle frontal superior parietal and both lateral occipital and paracentral gyrus. Volumes of left hippocampus, and periventricular WMH were also reduced in the Sarcopenia group. In addition, we found a significant positive correlation between the left precuneus thickness and muscle mass. Periventricular WMH volumes were also positively correlated with the 5CST score. CONCLUSION Sarcopenia affects cortical and subcortical structures in the cognitively normal older adults. These structural changes might be associated with underlying neurobiological mechanisms of sarcopenia in the cognitively normal older adults.

Abstract
Background Foreign-body aspiration is common in children aged 6 months to 3 years. However, with the aging population and increasing prevalence of disabilities such as hemiparesis and neuromuscular diseases in adults, an increased incidence of aspiration is expected. Methods This was a multicenter retrospective, observational study in four major referral hospitals in Daegu, South Korea, between 2000 and 2019. We included patients aged over 18 years who were evaluated for tracheobronchial foreign-body aspiration by flexible bronchoscopy. Comorbidities, type and location of foreign body, and radiologic findings were recorded. Results Of 138 patients who underwent flexible bronchoscopy for tracheobronchial foreign body aspiration, 91 (65.9%) were men; the mean age was 66.3 (range: 29–87) years. A history of definite choking was present in 60 (43.5%) patients. The most common site of the foreign body was the right bronchus intermedius (27.5%). The most common type of aspirated foreign body was teeth (37.7%), followed by chicken bone (15.2%), nuts (14.5%) and fish bone (9.4%). Iatrogenic events accounted for 37.0% of the cases of aspiration, and the foreign body was successfully removed by flexible bronchoscopy in 91.3% of cases. Conclusion Foreign-body aspiration is not rare, even in adults who do not have predisposing factors. Iatrogenic events accounted for about 40% of all cases of foreign body aspiration. In adults, flexible bronchoscopy is relatively safe and has a high success rate for foreign-body removal.

Abstract
Carbohydrate-restricted diets and intermittent fasting (IF) have been rapidly gaining interest among the general population and patients with cardiometabolic disease, such as overweight or obesity, diabetes, and hypertension. However, there are limited expert recommendations for these dietary regimens. This study aimed to evaluate the level of scientific evidence on the benefits and harms of carbohydrate-restricted diets and IF to make responsible recommendations. A meta-analysis and systematic literature review of 66 articles on 50 randomized controlled trials (RCTs) of carbohydrate-restricted diets and 10 articles on eight RCTs of IF was performed. Based on the analysis, the following recommendations are suggested. In adults with overweight or obesity, a moderately-low carbohydrate or low carbohydrate diet (mLCD) can be considered as a dietary regimen for weight reduction. In adults with type 2 diabetes mellitus, mLCD can be considered as a dietary regimen for improving glycemic control and reducing body weight. In contrast, a very-low carbohydrate diet (VLCD) and IF are recommended against in patients with diabetes. Furthermore, no recommendations are suggested for VLCD and IF in adults with overweight or obesity, and carbohydrate-restricted diets and IF in patients with hypertension. Here, we describe the results of our analysis and the evidence for these recommendations.

Abstract
Abstract
Glioblastoma multiforme (GBM) is the most common lethal primary brain tumor. Neural stem cells (NSCs) harboring cancer-driving mutations in the subventricular zone (SVZ) have recently been reported as the cells of origin for human glioblastoma (GBM) through migration. However, the pathological role of residual tumor-initiating NSCs (tNSCs) in the SVZ is undetermined for local recurrent tumor after surgical removal of the primary tumor. After the primary resection of GBM, most recurrences still appear as local tumors around the resection cavity (RC). Accordingly, we hypothesized that, after complete removal of the primary tumor, the tNSCs in SVZ might be the source for tumor construction at RC. Here, we examined the role of tNSCs in the development of local tumors around RC using a mouse model and genetic analysis of human tissues. First, cancer-driving mutations, including Trp53, Pten, and Egfr mutations, were introduced to NSCs in SVZ through in vivo electroporation, and the RC was generated in the remote cortex through stereotaxic resection. We found that the NSCs harboring driver mutations migrated specifically to the RC through the aberrant growth of oligodendrocyte-precursor cells (OPCs). Furthermore, the SVZ-originated cells constituted the GBM around the RC at four weeks post-resection in 64% of mouse models. Second, we performed deep sequencing of longitudinal matched tissues consisting of (i) normal SVZ away from the tumor, (ii) primary tumor, (iii) recurrent tumor, and (iv) blood in the patients with GBM, IDH wildtype. We found that the dominant clones of recurrent tumors genetically arose from the SVZ, not directly from the primary tumor. Third, the CXCR4/CXCL12 axis was upregulated through migration from the SVZ and tumor formation at the RC compared with primary tumors without the RC in mouse models. Blockage of the CXCR4/CXCL12 axis decreased the number of immigrating OPC lineage cells specifically and improved tumor control and survival rates. Taken together, our results reveal that the residual tNCSs harboring cancer-driving mutations in the SVZ can re-construct tumors after surgical resection of GBM. Blocking CXCL12/CXCR4 might be a potential treatment strategy for preventing the main local failures after resection.

Abstract
Abstract
Immune checkpoint inhibitors (ICI) targeting PD-1, PD-L1, or CTLA-4 have shown remarkable therapeutic outcomes in various cancers. However, the therapeutic efficacy of ICI-based immunotherapy in microsatellite stable (MSS) colorectal cancer (CRC) has been extremely limited. Recent studies strikingly revealed that the human gut microbiome controls the efficacy of immune checkpoint blockades. Yet, the effect of the gut microbiome on reinforcing the ICI efficacy in MSS tumors in CRC is unknown. Here, we suggest a microengineered CRC Chip that recapitulates the tumor microenvironment of individual CRC patients by introducing biopsy-derived colonic organoid epithelium. We have built a three-dimensional (3D) lumen-capillary interface under peristalsis-like motions and flow in an oxygen-controlled microenvironment. We leverage this pathomimetic CRC Chip to recapitulate the patient-specific tumor-microbiome-immune axis to demonstrate microbial immunomodulation on the tumor cells and cytotoxic tumor immunity. We co-cultured various human intestinal bacteria in a CRC Chip to assess the immunomodulatory contribution to the tumor epithelium. We found that living Bifidobacterium sp. significantly reduces the PD-L1 on the tumor surface, followed by elevated anti-tumor activity after CD8 T cell-mediated cytotoxic interactions. We envision that our CRC Chip model can potentially reduce the knowledge gap between the bench and bedside. Furthermore, our innovative CRC Chip model may potentially offer a platform to validate the “Druggable microbiome” and the utility of the patient’s avatar model for Precision Medicine.

Abstract
BACKGROUND This study investigated the association between the use of statins, the incidence of gastric, colorectal, and esophageal cancers, and mortality between January 2005 and June 2013 in South Korea. METHODS We compared patients aged 45-70 years statin users for at least 6 months to non-statin users matched by age and sex, from 2004 to June 2013 using the National Health Insurance database. Main outcomes were gastric, colorectal, and esophageal cancer incidence and mortality. Cox proportional hazard regression was used to calculate the adjusted hazard ratios (aHRs) and 95% confidence intervals (95% CIs) among overall cohort and matched cohort after propensity score matching with a 1:1 ratio. RESULTS Out of 1,008,101 people, 20,473 incident cancers, 3938 cancer deaths occurred and 7669 incident cancer, 1438 cancer death in matched cohort. The aHRs for the association between the risk of cancers and statin use were 0.7 (95% CI 0.65-0.74) for gastric cancer, 0.73 (95% CI 0.69-0.78) for colorectal cancer, and 0.55 (95% CI 0.43-0.71) for esophageal cancer. There were associations between statin use and decreased gastric cancer mortality (HR 0.46, 95% CI 0.52-0.57), colorectal cancer mortality (HR 0.43, 95% CI 0.36-0.51), and esophageal cancer mortality (HR 0.41, 95% CI 0.27-0.50) in the overall cohort and this pattern was similar in the matched cohort. DISCUSSION Statin use for at least 6 months was significantly associated with a lower risk of stomach, colorectal, and esophageal cancer incidence as well as cancer mortality after a diagnosis.

Abstract
The taxonomy of the extant dinoflagellate genus Gonyaulax is challenging since its thecate morphology is rather conservative. In contrast, cysts of Gonyaulax are varied in morphology and have been related with the fossil-based genera Spiniferites and Impagidinium. To better understand the systematics of Gonyaulax species, we performed germination experiments on cysts that can be identified as S. ristingensis, an unidentified Spiniferites with petaloid processes here described as Spiniferites pseudodelicatus sp. nov. and Impagidinium variaseptum from Chinese and Portuguese waters. Despite marked differences in cyst morphology, motile cells of S. pseudodelicatus and I. variaseptum are indistinguishable from Gonyaulax baltica. Motile cells hatched from S. ristingensis are morphologically similar to G. baltica as well but differ in the presence of one pronounced antapical spine. Three new species, Gonyaulax amoyensis (cyst equivalent S. pseudodelicatus), Gonyaulax bohaiensis (cyst equivalent I. variaseptum), and Gonyaulax portimonensis (cyst equivalent S. ristingensis), were erected. In addition, a new ribotype (B) of G. baltica was reported from South Korea and a bloom of G. baltica ribotype B is reported from New Zealand. Molecular phylogeny based on LSU and SSU rRNA gene sequences revealed that Gonyaulax species with minute or short antapical spines formed a well-resolved clade, whereas species with two pronounced antapical spines or lack of antapical spines formed the sister clade. Six strains of four above species were examined for yessotoxin production by liquid chromatography coupled with tandem mass spectrometry, and very low concentrations of yessotoxin were detected for one G. bohaiensis strain.

Abstract
BACKGROUND Carbohydrate-restricted diets and intermittent fasting (IF) have been rapidly gaining interest among the general population and patients with cardiometabolic disease, such as overweight or obesity, diabetes, and hypertension. However, there are limited expert recommendations for these dietary regimens. This study aimed to evaluate the level of scientific evidence on the benefits and harms of carbohydrate-restricted diets and IF to make responsible recommendations. METHODS A meta-analysis and systematic literature review of 66 articles on 50 randomized controlled clinical trials (RCTs) of carbohydrate-restricted diets and ten articles on eight RCTs of IF was performed. RESULTS Based on the analysis, the following recommendations are suggested. In adults with overweight or obesity, a moderately-low carbohydrate or low carbohydrate diet (mLCD) can be considered as a dietary regimen for weight reduction. In adults with type 2 diabetes, mLCD can be considered as a dietary regimen for improving glycemic control and reducing body weight. In contrast, a very-low carbohydrate diet (VLCD) and IF are recommended against in patients with diabetes. Furthermore, no recommendations are suggested for VLCD and IF in adults with overweight or obesity, and carbohydrate-restricted diets and IF in patients with hypertension. CONCLUSION Here, we describe the results of our analysis and the evidence for these recommendations.

Abstract
Colorectal cancer (CRC) is one of the life-threatening malignancies worldwide. Thus, novel potential therapeutic targets and therapeutics for the treatment of CRC need to be identified to improve the clinical outcomes of patients with CRC. In this study, we found that glucose-regulated protein 94 (GRP94) is overexpressed in CRC tissues, and its high expression is correlated with increased microvessel density. Next, through phage display technology and consecutive in vitro functional isolations, we generated a novel human monoclonal antibody that specifically targets cell surface GRP94 and shows superior internalizing activity comparable to trastuzumab. We found that this antibody specifically inhibits endothelial cell tube formation and simultaneously promotes the downregulation of GRP94 expression on the endothelial cell surface. Finally, we demonstrated that this antibody effectively suppresses tumor growth and angiogenesis of HCT116 human CRC cells without causing severe toxicity in vivo. Collectively, these findings suggest that cell surface GRP94 is a novel potential anti-angiogenic target in CRC and that antibody targeting of GRP94 on the endothelial cell surface is an effective strategy to suppress CRC tumor angiogenesis.

Abstract
Chronic stress contributes to the risk of developing depression; the habenula, a nucleus in epithalamus, is associated with many neuropsychiatric disorders. Using genome-wide gene expression analysis, we analyzed the transcriptome of the habenula in rats exposed to chronic restraint stress for 14 days. We identified 379 differentially expressed genes (DEGs) that were affected by chronic stress. These genes were enriched in neuroactive ligand-receptor interaction, the cAMP (cyclic adenosine monophosphate) signaling pathway, circadian entrainment, and synaptic signaling from the Kyoto Encyclopedia of Genes and Genomes pathway analysis and responded to corticosteroids, positive regulation of lipid transport, anterograde trans-synaptic signaling, and chemical synapse transmission from the Gene Ontology analysis. Based on protein-protein interaction network analysis of the DEGs, we identified neuroactive ligand-receptor interactions, circadian entrainment, and cholinergic synapse-related subclusters. Additionally, cell type and habenular regional expression of DEGs, evaluated using a recently published single-cell RNA sequencing study (GSE137478), strongly suggest that DEGs related to neuroactive ligand-receptor interaction and trans-synaptic signaling are highly enriched in medial habenular neurons. Taken together, our findings provide a valuable set of molecular targets that may play important roles in mediating the habenular response to stress and the onset of chronic stress-induced depressive behaviors.

Abstract
The habenula (Hb) is an epithalamic structure that links multiple forebrain areas with the mid/hindbrain monoaminergic systems. As an anti-reward center, it has been implicated in the etiology of various neuropsychiatric disorders, particularly those associated with dysregulated reward circuitry. In this regard, Hb has been proposed as a therapeutic target for treatment-resistant depression associated with a higher risk of suicide. Therefore, we aimed to gain insight into the molecular signatures of the Hb in association with suicide in individuals with major depression. Postmortem gene expression analysis identified 251 differentially expressed genes (DEGs) in the Hb tissue of suicides in comparison with Hb tissues from neurotypical individuals. Subsequent bioinformatic analyses using single-cell transcriptome data from the mouse Hb showed that the levels of a subset of endothelial cell-enriched genes encoding cell–cell junctional complex and plasma membrane-associated proteins, as well as the levels of their putative upstream transcriptional regulators, were significantly affected in suicides. Although our findings are based on a limited number of samples, the present study suggests a potential association of endothelial dysfunction in the Hb with depression and suicidal behavior.

Abstract
In vitro antioxidant activities of premature and mature mandarin peel and juice extracts were investigated for their potentials as functional food materials. Total phenolic and flavonoid content of premature and mature mandarin peel and juice was in the range of 31.20 to 94.04 mg gallic acid equivalent (GAE)/g and 0.09 to 43.99 mg quercetin equivalent (QE)/g, respectively. Among flavanone compounds, hesperidin and narirutin were identified as 76.81 and 51.35 mg/g, respectively, in the premature mandarin peel extract. Mandarin peel extracts were mostly high in in vitro antioxidant activities compared to mandarin juices. Hydrogen peroxide and hydroxyl radical scavenging activities (81.52-93.24%) of the premature mandarin peel extract were higher than DPPH and ABTS+ radical scavenging activities (24.03-30.39%). These results confirmed that the potential of premature mandarin peels as a natural antioxidant source for functional foods.

Based on the analysis, the following recommendations are suggested. In adults with overweight or obesity, a moderately-low carbohydrate or low carbohydrate diet (mLCD) can be considered as a dietary regimen for weight reduction. In adults with type 2 diabetes mellitus, mLCD can be considered as a dietary regimen for improving glycemic control and reducing body weight. In contrast, a very-low carbohydrate diet (VLCD) and IF are recommended against in patients with diabetes. Furthermore, no recommendations are suggested for VLCD and IF in adults with overweight or obesity, and carbohydrate-restricted diets and IF in patients with hypertension. Here, we describe the results of our analysis and the evidence for these recommendations.

Abstract
In emergency medicine, the lactate level is commonly used as an indicator of the severity and response to the treatment of hypoperfusion-related diseases. Clinical lactate measurements generally require 3 h for clinical determination. To improve the current gold standard methods, the development of sensor devices that can reduce detection time while maintaining sensitivity and providing portability is gaining great attention. This study aimed to develop a polyaniline (PAni)-based single-sensor platform for sensing lactate in human sweat using a CIELAB color system-based colorimetric device. To establish a lactate sensing platform, PAni nanoparticles were synthesized and adsorbed on the filter paper surface using solvent shift and dip-coating methods, respectively. PAni is characterized by a chemical change accompanied by a color change according to the surrounding environment. To quantify the color change of PAni, a CIELAB color system-based colorimetric device was fabricated. The color change of PAni was measured according to the chemical state using a combination of a PAni-based filter paper sensor platform and a colorimetric device, based on the lactate concentration in deionized water. Finally, human sweat was spiked with lactate to measure the color change of the PAni-based filter paper sensor platform. Under these conditions, the combination of polyaniline-based sensor platforms and colorimetric systems has a limit of detection (LOD) and limit of quantitation (LOQ) of 1 mM, linearity of 0.9684, and stability of 14%. Tbe confirmed that the color of the substrate changes after about 30 s, and through this, the physical fatigue of the individual can be determined. In conclusion, it was confirmed through this study that a combination of the PAni paper sensor platform and colorimeter can detect clinically meaningful lactate concentration.

Abstract
Cardiovascular disease is one of the leading causes of morbidity and mortality in recent years. The intake of polyphenol rich diets has been associated with improved cardiovascular function and reduced cardiovascular risks. Oryza sativa L. is one of the most common cereals worldwide. Rice bran, a byproduct of the rice milling process, contains many bioactive ingredients, including polyphenols, polysaccharides, proteins, and micronutrients. It is also consumed as a healthy diet in the form of rice bran oil and powder in many Asian countries like Japan, South Korea, and India for its several health benefits as a natural antioxidant. Thus, this study evaluated the vasorelaxant effect of ethanolic extracts of brown, green, red, and black rice bran and investigated its underlying vasorelaxant mechanism. Among the four rice bran extracts (RBEs) examined, the red rice bran extract (RRBE) had a strong endothelium-dependent vasorelaxant effect, which was markedly prevented by N-ω-nitro-L-arginine [endothelial nitric oxide synthase (eNOS) inhibitor], wortmannin [phosphoinositide-3 kinase (PI3K) inhibitor], and 1H-[1,2,4]oxadiazole[4,3-alpha]quinoxalin-1-one (inhibitor of guanylate cyclase). Likewise, RRBE induced the phosphorylation of eNOS and Src in cultured endothelial cells, thereby stimulating NO formation. Altogether, these findings propose that RRBE induces endothelium-dependent relaxation, involving at least in part, NO-mediated signaling through the PI3K/eNOS pathway. Further, LC-PDA analysis conducted on the four RBEs also revealed that RRBE highly contained taxifolin, which is an active flavanonol that induces endothelium-dependent vasorelaxation, compared to other RBEs. Subsequently, the underlying mechanism of taxifolin was assessed through vascular reactivity studies with pharmacological inhibitors similar to that of RRBE. These findings deciphered a distinct difference in vasorelaxant effects between RRBE and the other RBEs. We also observed that RRBE induced a potent endothelium-dependent NO-mediated relaxation in coronary artery rings, which involved the Src/PI3K pathway that activates eNOS. Additionally, taxifolin exhibited, at least in part, similar vasoprotective effects of RRBE. Therefore, we propose that RRBE may serve as natural sources of functional phytochemicals that improve cardiovascular diseases associated with disturbed NO production and endothelial dysfunction.

Abstract
Yakuchinone A (1) is a bioactive diarylheptanoid isolated from the dried fruits of Alpinia oxyphylla. Microbial transformation has been recognized as an efficient method to produce new biologically active derivatives from natural products. In the present study, microbial transformation of yakuchinone A was performed with the fungus Mucor hiemalis KCTC 26779, which led to the isolation of nine new metabolites (2, 3a, 3b, and 4–9). Their structures were elucidated as (3S)-oxyphyllacinol (2), (3S,7R)- and (3S,7S)-7-hydroxyoxyphyllacinol (3a and 3b), (3S)-oxyphyllacinol-4′-O-β-d-glucopyranoside (4), (3S)-4″-hydroxyoxyphyllacinol (5), (3S)-3″-hydroxyoxyphyllacinol (6), (3S)-2″-hydroxyoxyphyllacinol (7), (3S)-2″-hydroxyoxyphyllacinol-2″-O-β-d-glucopyranoside (8), and (3S)-oxyphyllacinol-3-O-β-d-glucopyranoside (9) based on the comprehensive spectroscopic analyses and the application of modified Mosher’s method. All compounds were evaluated for their cytotoxic activities against melanoma, as well as breast, lung, and colorectal cancer cell lines. Compound 9, which was O-glucosylated on the diarylheptanoid alkyl chain, exhibited the most selective cytotoxic activities against melanoma cell lines with the IC50 values ranging from 6.09 to 9.74 μM, indicating that it might be considered as a possible anti-cancer lead compound.

Abstract
BACKGROUND AND AIM Gallstones have been reported to be positively associated with hepatobiliary cancers. However, risks of these cancers by cholecystectomy or in patients with complicated gallstones are controversial. We studied the effect of cholecystectomy on the risk of cholangiocarcinoma (CCA) or hepatocellular carcinoma (HCC) in patients with gallstones and subgroup of complicated gallstones. METHODS Patients with gallstone disease (n = 958 677) and age-matched and sex-matched controls (n = 9 586 770) were identified using the Korean National Health Insurance database. Complicated gallstones were defined as gallstones associated with acute cholecystitis or acute cholangitis. Adjusted hazard ratios (adjusted hazard ratios, 95% confidence interval) of CCA and HCC incidences were evaluated in patients with gallstones who received cholecystectomy compared to the controls. We also analyzed these effects in patients with complicated gallstones. RESULTS Patients with gallstones showed increased risks of CCA (1.80, 1.67-1.93) and HCC (1.03, 1.00-1.07) compared with controls. Cholecystectomy had minimal effects on the risks of CCA (1.94, 1.76-2.14) and HCC (0.93, 0.87-0.99) compared with those without cholecystectomy. However, patients with complicated gallstones showed highly increased CCA risk (5.62, 4.89-6.46) and a 30% risk reduction after cholecystectomy (3.91, 3.43-4.46). Risk reduction by cholecystectomy was greater for extrahepatic CCA than for intrahepatic CCA or ampulla of Vater cancer. However, the risk of HCC was not different in patients with complicated gallstones and those who underwent cholecystectomy compared to controls. CONCLUSION The risk of CCA was markedly increased in patients with complicated gallstones and was partially reduced by cholecystectomy. The risk change of HCC was minimal with gallstones or cholecystectomy.

Abstract
Human spinal-cord-like tissues induced from human pluripotent stem cells are typically insufficiently mature and do not mimic the morphological features of neurulation. Here, we report a three-dimensional culture system and protocol for the production of human spinal-cord-like organoids (hSCOs) recapitulating the neurulation-like tube-forming morphogenesis of the early spinal cord. The hSCOs exhibited neurulation-like tube-forming morphogenesis, cellular differentiation into the major types of spinal-cord neurons as well as glial cells, and mature synaptic functional activities, among other features of the development of the spinal cord. We used the hSCOs to screen for antiepileptic drugs that can cause neural-tube defects. hSCOs may also facilitate the study of the development of the human spinal cord and the modelling of diseases associated with neural-tube defects.

Abstract
Tissue clearing for 3-dimensional (3D) imaging is increasingly utilized in many biomedical applications, including the pathological examination of human biopsy specimens. Although many protocols offer rapid and efficient tissue clearing (>1 d), immunofluorescence labeling of thick specimens is a highly time-consuming process. The use of low molecular weight chemical dyes has potential benefits in terms of speed and quality of 3D labeling. Accordingly, we tested several chemical dyes to assess their potential applications in 3D imaging. The combination of SYTO 16 and eosin (S&E) was found to be a potential fluorescent version of the hematoxylin–eosin (H&E) stain. Furthermore, picrosirius red (for collagen), Congo red (for senile plaques), and fluorescent Nissl (for neurons in the normal brain or blood vessels in the injured brain) stains can be used alone or in combination with antibody labeling. As chemical labeling requires a relatively short incubation time (<1 d), fluorescent chemical dyes could expedite the 3D imaging process.

Abstract
BACKGROUND The renoprotective effects of erythropoietin (EPO) are well-known; however, the optimal timing of EPO administration remains controversial. Red blood cell (RBC) transfusion is an independent risk factor for cardiac surgery-associated acute kidney injury (CSA-AKI). We aimed to evaluate the efficacy of EPO on CSA-AKI and RBC transfusion according to the timing of administration. METHODS We searched the Cochrane Library, EMBASE, and MEDLINE databases for randomized controlled trials. The primary outcome was the incidence of CSA-AKI following perioperative EPO administration, and the secondary outcomes were changes in serum creatinine, S-cystatin C, S-neutrophil gelatinase-associated lipocalin, urinary neutrophil gelatinase-associated lipocalin, length of hospital and intensive care unit (ICU) stay, volume of RBC transfusion, and mortality. The subgroup analysis was stratified according to the timing of EPO administration in relation to surgery. RESULTS Eight randomized controlled trials with 610 patients were included in the study. EPO administration significantly decreased the incidence of CSA-AKI (odds ratio: 0.60, 95% confidence interval [CI]: 0.43-0.85, P = .004; I2 = 52%; P for heterogeneity = .04), intra-operative RBC transfusion (standardized mean difference: -0.30, 95% CI: -0.55 to -0.05, P = .02; I2 = 15%, P for heterogeneity = .31), and hospital length of stay (mean difference: -1.54 days, 95% CI: -2.70 to -0.39, P = .009; I2 = 75%, P for heterogeneity = .001) compared with control groups. Subgroup analyses revealed that pre-operative EPO treatment significantly reduced the incidence of CSA-AKI, intra-operative RBC transfusion, serum creatinine, and length of hospital and ICU stay. CONCLUSION Pre-operative administration of EPO may reduce the incidence of CSA-AKI and RBC transfusion, but not in patients administered EPO during the intra-operative or postoperative period. Therefore, pre-operative EPO treatment can be considered to improve postoperative outcomes by decreasing the length of hospital and ICU stay in patients undergoing cardiac surgery.

Abstract
BACKGROUND & AIMS Donor death is the most serious complication of living liver donation but is reported rarely. We investigated the actual mortality of living liver donors (LLDs) compared with matched control groups based on analysis of the Korean National Health Insurance Services (NHIS) database. METHODS This cohort study included 12,372 LLDs who donated a liver graft between 2002 and 2018, and were registered in the Korean Network for Organ Sharing. They were compared to 3 matched control groups selected from the Korean NHIS and comprising a total of 123,710 individuals: healthy population (Group I); general population without comorbidities (Group II); and general population with comorbidities (Group III). RESULTS In this population, 78.5% of living liver donors were 20-39 years old, and 64.7% of all donors were male. Eighty-nine donors (0.7%) in the LLD group died (68 males and 21 females), a mortality rate (/1,000 person-years) of 0.91 (0.74-1.12). Mortality rate ratio and the adjusted hazard ratio of the LLD group was 2.03 (1.61-2.55) and 1.71 (1.31-2.25) compared to Control Group I, 0.75 (0.60-0.93) and 0.63 (0.49-0.82) compared to Control Group II, and 0.58 (0.46-0.71) and 0.49 (0.39-0.60) compared to Control Group III. LLD group, depression, and lower income were risk factors for adjusted mortality. The incidence of liver failure, depression, cancer, diabetes, hypertension, brain infarction, brain hemorrhage, and end-stage renal disease in the LLD group was significantly higher than in Control Group I. CONCLUSIONS Outcomes of the LLD group were worse than those of the matched healthy control group despite the small number of deaths and medical morbidities in this group. LLDs should receive careful medical attention for an extended period after donation. LAY SUMMARY The incidence of mortality, liver failure, depression, cancer, diabetes, hypertension, brain infarction, brain hemorrhage, and end-stage renal disease in the living liver donor group was significantly higher than in the matched healthy group. Careful donor evaluation and selection processes can improve donor safety and enable safe living donor liver transplantation.

Abstract
Redox activity is known to regulate migration, invasion, metastasis, proliferation, and vascularization of cancer. Because cancer is heterogeneous, the role of redox activity in different cancers and cancer-related processes vary widely. In this study, water soluble, Tween 80-coated polyaniline (TPAni) nanoparticles were synthesized and used as nano-agents for sensing the redox activities of various cancer cells. To identify the relationship between the redox activity and the aggressiveness of cancer cells, two different cancer cell lines, derived from the same tissue but different with regards to aggressiveness, were selected for study. First, the cancer cell lines were incubated with TPAni nanoparticles, and an absorbance ratio obtained from the cell culture media was used as a colorimetric indicator of the redox activities of the cells. Simultaneously, hydrophobically modified filter papers coated with silver nanosnowflakes (SNSF) were used as sensing substrates for surface enhanced Raman scattering (SERS). SERS spectra obtained from varying concentrations of rhodamine 6G were used to confirm the detection limit of the SNSF-based SERS substrate. Cell culture media containing TPAni nanoparticles were treated with the SNSF-containing SERS substrates to examine the redox activities of the various cancer cell lines.The redox activities of cancer cell lines were confirmed by absorbance spectral analysis, and these redox activities were better identified via an SERS analysis method. A SNSF-containing SERS substrate, fabricated from SNSF and filter paper, was used to sense redox activity in cancer cell lines and to further identify correlations between redox activity and cancer cell line aggressiveness, as indicated by the use of EpCAM as a biomarker. Finally, potential of in vivo redox activity sensing was also confirmed.
