Abstract
The 3 major subphenotypes observed in patients with nonsyndromic orofacial clefts (NSOFCs) are nonsyndromic cleft lip only (NSCLO), nonsyndromic cleft lip with palate (NSCLP), and nonsyndromic cleft palate only (NSCPO). However, the genetic architecture underlying NSCPO is largely unknown. Here we performed a 2-stage genome-wide association study (GWAS) on NSCPO and replication analyses of selected variants in other NSOFCs from the Chinese Han population. We identified a novel locus (15q24.3) and a known locus (1q32.2) where variants in or near the gene reached genome-wide significance (2.80 × 10-13 < P < 1.72 × 10-08) in a test for association with NSCPO in a case-control design. Although a variant from 15q24.3 was found to be significantly associated with both NSCPO and NSCLP, the direction of estimated effects on risk were opposite. Our functional annotation of the risk alleles within 15q24.3 coupled with previously established roles of the candidate genes within identified risk loci in periderm development, embryonic patterning, and/or regulation of cellular processes supports their involvement in palate development and the pathogenesis of cleft palate. Our study advances the understanding of the genetic basis of NSOFCs and provides novel insights into the pathogenesis of NSCPO.

Abstract
Background: Oral infectious diseases are typified by dental caries and periodontal diseases and are known to be associated with various systemic diseases. However, clear associations between occlusal disorders and systemic diseases have not yet been established. We investigated the association between an awareness of malocclusion and common diseases in late adolescence. Methods: We retrospectively reviewed the data of mandatory medical questionnaires that are a legal requirement of the freshman medical checkup. We collected the data of all the students who completed the questionnaires between April 2017 and 2019. The data were analyzed using the χ2 test and multivariate analysis was performed with a binomial logistic regression model. Results: The subjects were 9098 students aged 17–19 (mean age 18.3 years). The rate of awareness of malocclusion was 2.14% (195 out of 9098 eligible subjects; 160 males and 35 females). These students had significantly greater rates of allergic rhinitis, asthma, and arrhythmia (p < 0.001). Multivariate analysis revealed significant rates of allergic rhinitis (odds ratio [OR] 2.184, 95% confidence interval [CI]: 1.468–3.250, p < 0.001), asthma (OR 1.843, 95%CI: 1.153–2.945, p = 0.011), and arrhythmia (OR 2.809, 95%CI: 1.083–7.288, p = 0.034) among students with an awareness of malocclusion. Conclusion: We identified close associations between an awareness of malocclusion and systemic diseases including allergic rhinitis, asthma, and arrhythmia in the late adolescent population. These results reinforce the associations between malocclusion and allergic rhinitis and asthma, as well as providing novel insight into the association of malocclusion and arrhythmia. However, further research is necessary to confirm the associations and explore the mechanisms underlying these associations.

Abstract
OBJECTIVE This project is aimed at investigating whether CircANXA2 can promote the apoptosis of myocardial cells by inhibiting miR-133 expression and thereby participate in the development of myocardial ischemia-reperfusion injury. Materials and Method. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of CircANXA2 in H9c2 cells after hypoxia/reoxygenation (H/R) treatment. Evaluation of myocardial injury markers in H9c2 cells was performed using commercial kits, including lactate dehydrogenase (LDH), malonaldehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidation (GSH-PX). MTT analysis and flow cytometry were used to detect myocardial cell proliferation and apoptosis, respectively. Western blot was used to detect the protein expression of apoptosis-related genes. RESULT qRT-PCR results showed that compared with the control, the expression of CircANXA2 was upregulated and the expression level of miR-133 was significantly decreased in H/R-treated H9c2 cells. CircANXA2 overexpression increased LDH, MDA, SOD, and GSH-PX activity in H/R-treated H9c2 cells. At the same time, CircANXA2 overexpression inhibited the proliferation of H/R-treated cells, and CircANXA2 was able to induce cardiomyocyte apoptosis. Western blot results showed that after overexpression of CircANXA2, the proapoptotic genes Bax and cytochrome C was upregulated, while the antiapoptotic gene Bcl-2 was downregulated. In H9c2 cells, upregulating miR-133 can reverse the inhibition of proliferation induced by CircANXA2 overexpression and increase apoptosis. CONCLUSIONS CircANXA2 promotes cardiomyocyte apoptosis in myocardial ischemia-reperfusion injury by inhibiting the expression of miR-133. CircANXA2 may be a potential target for myocardial ischemia-reperfusion injury.

Abstract
BACKGROUND Though it is well known that periodontal diseases are associated with various systemic diseases in adults, the associations in late adolescents have not been adequately elucidated. We investigated the association between gum bleeding (a major symptom of periodontal diseases) and common systemic diseases in late adolescents: allergic, respiratory, and otorhinolaryngologic diseases. METHODS We conducted a retrospective review of the mandatory medical questionnaires administered as a part of legally required freshman medical checkup between April 2017 and April 2019 at the University of Tokyo. Among the total of 9376 sets of responses, 9098 sets from students aged less than 20 were analyzed. An χ2 test and univariate and multivariate binomial logistic regression analyses were performed using SAS ver. 9.4. A value of p < 0.05 was accepted as significant. RESULTS According to the questionnaire data, 3321 students (36.5%; 2780 males and 541 females) responded that they experienced gum bleeding whenever they brushed their teeth. These students had significantly higher incidence rates of otitis media/externa and asthma/cough-variant asthma (p = 0.001 and p = 0.006, respectively). The results of the multivariate analysis showed significant rates of the following complications among these students: (1) otitis media/externa (odds ratio (OR) 1.691; 95% confidence interval (CI): 1.193-2.396; p = 0.003), (2) asthma/cough-variant asthma (OR 1.303; 95% CI: 1.091-1.556; p = 0.003), and (3) male gender (OR 1.536; 95% CI: 1.337-1.765; p < 0.001). CONCLUSIONS Gum bleeding was closely associated with otitis media/externa and asthma in late adolescents. Our study reinforces new evidence about the association between periodontal diseases and asthma, and it reveals a novel and close association between gum bleeding and otitis media/externa.

Abstract
OBJECTIVE LncRNA Fendrr plays an important role in cardiac development, but its role in myocardial ischaemia-reperfusion (I/R) injury remains unclear. P53 has been shown to be an important regulator of apoptosis and is involved in myocardial I/R-induced apoptosis. This study aims at investigating whether Fendrr affects hypoxia/reoxygenation (H/R)-induced cardiomyocyte apoptosis through p53. METHODS The left anterior descending coronary artery of the rat was ligated for 30 min and then reperfusion for 120 min by releasing the suture. Neonatal rat ventricular myocytes (NRVM) and rat cardiac cell line H9c2 were cultured for 6 h in hypoxia (95% N2 and 5% CO2 ), followed by reoxygenation (95% air and 5% CO2 ) for 6 h. Transfection were performed in cells. Apoptosis was detected by flow cytometry. Moreover, RNA pull-down, RNA immunoprecipitation, ubiquitination assay, GST pull-down assay and co-immunoprecipitation were used to detect the regulation of Fendrr on p53 protein. KEY FINDINGS Fendrr was decreased in I/R-induced myocardium and H/R-induced cardiomyocyte, and overexpression of Fendrr inhibited H/R-induced NRVM or H9c2 cells apoptosis. Further research found that the 1381-2100 nt of Fendrr bound to p53 protein and Fendrr promoted t direct binding of p53 to Cop1. The inhibition of Fendrr reduced the binding of E3 ubiquitin-protein ligase constitutive photomorphogenesis protein 1 (COP1) to p53 and reduced the ubiquitination of p53. Furthermore, the inhibition of Fendrr on H/R-induced NRVM or H9c2 cells apoptosis could be reversed by overexpression of p53. CONCLUSIONS Fendrr can inhibit H/R-induced cardiomyocyte apoptosis, which is partly through promoting the ubiquitination and degradation of p53 by increasing the binding of Cop1 and p53.

Abstract
BACKGROUND Many clinical studies for the long-term survival or efficacy of capecitabine plus oxaliplatin (XELOX) in colon cancer have already been studied, but its clinical benefit is controversial.
AIM To evaluate the long-term efficacy of XELOX regimen in comparison with other adjuvant chemotherapy protocols in colon cancer.
METHODS By searching the PubMed, EMBASE and Cochrane databases, a total of 12 randomized controlled trials involving 6698 stage III colon cancer cases (XELOX protocol: n = 3298 cases; other adjuvant chemotherapy protocol: n = 3268 cases) were included. The parameter outcomes included the overall survival and the disease-free survival. The quality control of selected literature was based on the Jadad scale and the GRADE system.
RESULTS In comparison to other adjuvant chemotherapy regimen, XELOX regimen showed a better overall survival (odds ratio = 1.29, 95% confidence interval: 1.15-1.44, P < 0.0001) and a better disease-free survival (odds ratio = 1.32, 95% confidence interval: 1.18-1.46, P < 0.0001) for colon cancer patients, suggesting the XELOX regimen can be a good option for postoperative treatment of stage III colon cancer.
CONCLUSION The XELOX regimen can be a preferred option for adjuvant treatment of stage III colon cancer after surgery.

Abstract
The underlying mechanism involved in auditory neuropathy spectrum disorder (ANSD) remains largely unclear. It has been previously reported that mutations in the apoptosis-inducing factor (AIF) gene are associated with auditory neuropathy and delayed peripheral neuropathy, which can eventually cause ANSD. In the present study, the regulatory effects of AIF knockdown on the cellular functions of spiral ganglion neurons (SNGs) and the molecular mechanism(s) of AIF knockdown in inducing cell apoptosis in SGNs were further investigated. The results showed that the AIF knockdown via siRNA transfection resulted in high levels of oxidative stress, and impaired mitochondrial respiration activity and membrane potential in SGNs. Western blotting further proved that the knockdown of AIF can decrease the content of anti-apoptotic and anti-oxidative proteins, as well as mitochondrial respiratory chain Complex I proteins. The present experimental data suggested that the abnormal expression of AIF may affect SGNs cellular function, and may contribute to the progress of ANSD.

Abstract
The effects of post-mastectomy radiotherapy (PMRT) on different subtypes of T1-2N1M0 breast cancer remain controversial. Patients with T1-2N1M0 breast cancer treated by mastectomy or mastectomy and PMRT were identified from the 2010–2013 dataset from the Surveillance, Epidemiology and End Results (SEER) registry. A total of 7,466 patients with the 7th American Joint Committee on Cancer stage (Tumor-Node-Metastasis stages 1–2, 1 and 0, respectively) including 2,760 cases (36.97%) treated by mastectomy and PMRT and 4,706 cases (63.03%) treated by mastectomy alone were analyzed in this study. The follow-up time for patients in the dataset used from the SEER registry was 0–59 months. The breast cancer-specific survival (BCSS) of the patients was derived from the SEER dataset and stratified by treatment approach. A propensity score matching (PSM) analysis (experimental group: Control group ratio, 1:1) was conducted. Using univariate and multivariate analyses Cox proportional hazards analyses, PMRT was identified as an independent prognostic factor for triple-negative breast cancer (TNBC). Before PSM analysis, the BCSS favored PMRT in the hormone receptor (HR)+/human epidermal growth factor receptor 2 (HER2)+ (P=0.025) and HR−/HER2− groups (P=0.010) but not in the HR+/HER2− (P=0.346) and HR−/HER2+ (P=0.288) groups. Following PSM analysis, BCSS favored PMRT alone in the TNBC (HR−/HER2−) group (P=0.025). Patients with T1-2N1M0 TNBC may benefit from radiotherapy post-mastectomy.

Abstract
Retroperitoneal liposarcoma (RPLS) is a very rare type of tumor, accounting for less than 1% of all malignancies, especially the “large retroperitoneal liposarcoma” (GRPLS) of more than 20 kg (kilograms). Herein, we describe the treatment experience in a case of recurrent GRPLS. A 70-year-old woman was admitted with an enlarged abdomen, and computed tomography (CT) showed a large, low-density, homogeneous retroperitoneal mass (40×37×26 cm). In laparotomy, this 55×40×20 cm liposarcoma was completely removed and pathologically diagnosed as low-grade myxoid liposarcoma. The patient did not receive any adjuvant therapy, and CT showed no evidence of recurrence during follow-up.

Abstract
Progressive lung injury and pulmonary inflammation can be induced by an intraperitoneal injection of lipopolysaccharide (LPS). Interleukin-1β (IL-1β) is a key pro-inflammatory cytokine that can further exaggerate inflammation, which is cleaved and activated by the NALP3 inflammasome. Although the nuclear receptor Rev-erbα attenuates the level of LPS-induced pulmonary inflammation, the mechanism remains unclear. In this study, we investigated the influence of LPS-induced production of IL-1β and Rev-erbα on the development of lung inflammation. Herein, we demonstrate that Rev-erbα reduces IL-1β production and lung injury following an intraperitoneal injection of LPS, which is dependent on the NF-κB/NALP3 pathway. Thus, Rev-erbα is able to decrease the extent of acute lung injury by regulating IL-1β production. This mechanism may represent a potential novel therapeutic approach for lung injury.

Abstract
Peritoneal loose body (PLB) is a rare finding and it is usually incidentally discovered during laparotomy, examination or autopsy, as it is usually asymptomatic or presents with non-specific symptoms. In particular, giant PLBs, measuring >50 mm in maximum diameter, are even more rare, and only a few cases of laparoscopic extraction of these giant bodies have been reported in the literature to date. We herein describe our experience with the diagnosis and treatment of a giant PLB in a 49-year-old male patient who was admitted with complaints of intermittent pain the in lower abdomen 3 months earlier. An abdominal computed tomography scan revealed a 5.5x5.0-cm midline mass with central high density. The diagnosis was confirmed by open surgery and postoperative pathological examination. The postoperative recovery of the patient was uneventful and he was discharged from the hospital 7 days after surgery.

Abstract
BACKGROUND Microvascular changes play a decisive role in systemic sclerosis (SSc) and occur early in the course of the disease. Pulmonary arterial hypertension (PAH) represents one of the main clinical expressions of the vascular changes in SSc, and the abnormal changes, especially capillary density and capillary width, are detectable at nailfold videocapillaroscopy (NVC). AIMS To investigate the differences in capillary nailfold changes in SSc patients with and without PAH and to estimate the early diagnostic value of NVC in SSc secondary PAH (SSc-PAH). METHODS A comprehensive literature search of MEDLINE and PUBMED was performed to identify published studies without language restrictions. The methodological quality of the included studies was evaluated. The pooled specificity, sensitivity, positive likelihood rate, negative likelihood rate, diagnostic odds ratio, area under the curve and Q value were found using Meta-Disc version 1.4 software packages. Finally, seven studies were included in this meta-analysis. RESULTS The meta-analysis demonstrated that the diagnostic odds ratio, area under the curve and Q value were 5.84 (95% confidence interval: 1.95-17.54), 0.79 and 0.72 respectively. It indicated that the microvascular changes detected at NVC were significant in SSc-PAH and especially showed significantly lower capillary density and higher capillary width. CONCLUSION The NVC may be a valuable tool for the early diagnosis of SSc-PAH. It can detect the early microvascular changes associated with the risk of PAH and has a significant role in the early prediction of SSc-PAH.

Abstract
Long-term memory formation requires gene expression and new protein synthesis. MicroRNAs (miRNAs), a family of small non-coding RNAs that inhibit target gene mRNA expression, are involved in new memory formation. In this study, elevated miR-151-5p (miR-151) levels were found to be responsible for hippocampal contextual fear memory formation. Using a luciferase reporter assay, we demonstrated that miR-151 targets APH1a, a protein that has been identified as a key factor in γ-secretase activity, namely APH1a. Blocking miR-151 can upregulate APH1a protein levels and subsequently impair hippocampal fear memory formation. These results indicate that miR-151 is involved in hippocampal contextual fear memory by inhibiting APH1a protein expression. This work provides novel evidence for the role of miRNAs in memory formation and demonstrates the implication of APH1a protein in miRNA processing in the adult brain.

Abstract
Aneuploidy refers to aberrancies in cellular chromosome count, which is prevalent in most human cancers. Chemotherapy is an effective cancer treatment; however, the development of drug resistance is a major concern of conventional chemotherapy. The chemotherapy agent hydroxyurea (HU) targets proliferating cells and has long been applied to treat various human cancers. It remains elusive whether aneuploidy affects the drug sensitivity of hydroxyurea. By generating an inducible aneuploidy model, we found that aneuploid colon cancer cells were resistant to HU treatment compared to euploid controls. Surprisingly, further analyses showed that the HU resistance was dependent on the expression of wild type p53. Activation of the p53 pathway in aneuploidy cells reduced cell proliferation but generated resistance of tumor cells to HU treatment. HU resistance was abrogated in aneuploid cells if p53 was absent but re-gained when inducing proliferation repression in cells by serum deprivation. Our results demonstrate that the HU resistance developed in aneuploid colon cancer cells is mediated by wild type p53 and indicates the prognostic value of combining karyotypic and p53 status in clinical cancer treatment.

Abstract
Background Cancers of unknown primary origin (CUPs) are reported to be the 3-4th most common causes of cancer death. Recent years have seen advances in mutational analysis and genomics profiling. These advances could improve accuracy of diagnosis of CUPs and might improve the prognosis of patients with CUPs. Case presentation A 76-year old male with an adenocarcinoma of unknown primary origin in the lung presented with another tumor of the palate mucosa. The tumor cells in the pleural effusion were all negative for immunohistochemical markers (TTF-1 and Napsin A) and lung-specific oncogenic driver alterations (EGFR mutation and ALK translocation). The tumor of the palate mucosa was likewise identified as an adenocarcinoma, and the cells showed cytological similarities with the tumor cells in the pleural effusion; TTF-1, Napsin A, EGFR mutation and ALK translocation were all negative. This result suggested that origins of the tumors of the palate mucosa and in the lung were the same, even though the origin had not yet been determined. Next, we addressed whether the tumor of the palate mucosa was a primary tumor or not. Secretory carcinoma (SC), which is a common type of minor salivary gland tumor (MSGT), was suspected; however, mammaglobin was negative and ETV6-NTRK3 (EN) fusion was not observed. Other MSGTs were excluded based on histological and immunohistochemical findings. Furthermore, an additional examination demonstrated an oncogenic KRAS mutation at codon 12 (p.G12D) in both palate tumor and in pleural effusion. KRAS mutation is known to exist in one-third of lung adenocarcinomas (LUADs), but quite rare in MSGTs. The possibility of metastasis from other organs was considered unlikely from the results of endoscopic and imaging studies. This result indicated that the primary site of the CUP was indeed the lung, and that the tumor of the palate mucosa was a metastasis of the LUAD. Conclusions A tumor of the palate mucosa that showed diagnostic difficulties was determined to be a metastatic LUAD by genomic alterations and histopathological findings.

Abstract
BACKGROUND Until now, little is known about the role of miRNAs in the invasion and metastasis of Laryngeal squamous cell carcinoma (LSCC). OBJECTIVES This study aimed to explore the relationship between microRNA and the invasion and metastasis of LSCC. MATERIAL AND METHODS The highly metastatic laryngocarcinoma cells were obtained from the established animal model with spontaneous lymph node metastasis of LSCC in our previous study. MicroRNA expression profiling and bioinformatic analysis were performed to analyze the microRNA expression changes in the highly metastatic laryngocarcinoma cells and the parental tumor cells (HEP-2). RT-PCR was performed for further validation of the result of microarray. RESULTS A total of 40 microRNAs were found to be significantly altered in the highly metastatic laryngocarcinoma cells compared to controls. Bioinformatic analysis identified that 19 key microRNAs might involve in LSCC development. Moreover, RT-PCR confirmed that miR-25, miR-100, miR-125b-5p and let-7g were differentially expressed in different laryngocarcinoma cells and human tumor specimens. CONCLUSIONS AND SIGNIFICANCE Our findings suggest that microRNA play an important role in the invasion and metastasis of LSCC, and provide the clues for studying the function of microRNA as well as opportunities to analyze the complex molecular abnormalities driving LSCC progression.

Abstract
Background/Aim The feasibility of using laparoscopic gastrectomy for the treatment of Siewert-type II/III adenocarcinoma of the esophagogastric junction (AEG) has not been addressed. This study aimed to comparatively evaluate the short- and long-term effects on laparoscopic versus open surgery using (propensity score matching) PSM for Siewert-type II/III AEG. Methods We retrospectively collected data from the patients with Siewert-type II/III AEG who were treated in our cancer center between January 2013 and December 2015. Patients undergoing laparoscopic gastrectomy and open gastrectomy were matched via PSM. The cumulative 2-year Overall survival (OS) rate of patients in the two cohorts was estimated by Kaplan-Meier plots. Multi-variable analysis using a Cox regression model was conducted to identify independent risk factors. Results A total of 963 patients with Siewert-type II/III AEG were included, of which 132 cases were in the laparoscopic gastrectomy group, and 831 cases were in the open gastrectomy group. After regrouping with PSM, 132 patients in the laparoscopic gastrectomy group were balanced with 264 similar patients in the open gastrectomy group. As expected, the laparoscopic gastrectomy group had significantly longer operation times, but less blood loss. Furthermore, the two groups showed similar results for post-operative complications, duration of hospital stay and 2-year OS rate. Combined organ resection was an independent risk factor for 2-year OS rate. Conclusion This study suggests that laparoscopic gastrectomy may serve as a safe and feasible treatment for Siewert-type II/III AEG and achieve similar oncologic outcomes as open gastrectomy.

Abstract
Soluble fibrinogen-like protein 2 (sFGL2) could ameliorate acute rejection (AR) in rat cardiac transplantation. However, the role of sFGL2 in AR of liver transplantation has not been addressed. In this study, we found that FGL2 was upregulated in rat orthotropic liver transplantation (OLT) models of tolerance and positive correlation with the frequency of M2 Kupffer cells (KCs). Gain-of-function experiments in vitro showed that sFGL2 promoted the secretion of anti-inflammatory cytokines (IL-10, TGF-β) and the expression of CD206, and inhibited the activities of STAT1 and NF-κB signaling pathway. Consistently, in vivo assays showed that adeno-associated virus-mediated FGL2 (AAV-FGL2) transfer to recipients could ameliorate AR of rat OLT and induce KCs M2 polarization in allografts. Notably, we found that the recipients receiving transferred KCs from AAV-FGL2-treated allograft showed alleviated AR. Taken together, we revealed that sFGL2 ameliorated AR by inducing KCs M2 polarization.

Abstract
Chronic hepatitis B virus (HBV) infection remains one of the leading causes of hepatocellular carcinoma (HCC) globally. However, the mechanism underlying the mediation by HBV surface proteins (HBsAgs) of the early steps in the virus life cycle and following HCC development is unclear. β‑2‑glycoprotein I (β2GPI) specifically interacts with HBsAg and demonstrates high expression during the earliest stages of hepatitis B virus infection. In the present study, the assessment of HCC and adjacent tissues revealed that the levels of mRNA and protein of β2GPI were highly expressed in HBV‑related HCC. Previous studies have reported that HBsAg activates the nuclear factor (NF)‑κB pathway via interaction with β2GPI in HCC. However, the underlying mechanism of how the interaction between HBsAg and β2GPI confers activation of the NF‑κB pathway is still unclear. The HBsAg is comprised of three carboxyl‑co‑terminal HB proteins. In the present study, immunofluorescence assay and EMSA consistently revealed that a combination of recombinant small HBV surface antigen (rSHB) and β2GPI can significantly activate the NF‑κB signaling pathway. Another study from our team revealed that high expression of β2GPI enhanced HBsAg binding to cell surfaces and its interaction with Annexin II. However, Annexin II is not a transmembrane protein. Therefore, by a knockdown experiment with TLR2, TLR4 or MyD88 siRNAs using cells with co‑incubated HBsAg/β2GPI, certain aspects of the mechanism through which the HBsAg/β2GPI complex activates the NF‑κB pathway through the Toll‑like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/IκBα axis were explained. In the present study, we identified the functional domain of HBsAg co‑interaction with β2GPI for the activation of NF‑κB and revealed the mechanism of the HBsAg/β2GPI‑activated NF‑κB pathway which could contribute to the treatment of HBV‑related HCC. A novel finding of the present study is that HBsAg can bind to β2GPI. We first identified the functional domain of HBsAg with β2GPI to activate NF‑κB. Second, by siRNA knockout experiments, we identified the downstream molecules involved in the activation of NF‑κB induced by β2GPI/HBsAg. In addition, we found that HBsAg/β2GPI activated the NF‑κB pathway through the phosphorylation of Ser32/36 by IκBα.

Abstract
Alterations in adult neurogenesis have been regarded as a major cause of cognitive impairment in Alzheimer's disease (AD). The underlying mechanism of neurogenesis deficiency in AD remains unclear. In this study, we reported that Integrin-linked Kinase (ILK) protein levels and phosphorylation were significantly decreased in the hippocampus of APP/PS1 mice. Increased ILK expression of dentate gyrus (DG) rescued the hippocampus-dependent neurogenesis and memory deficits in APP/PS1 mice. Moreover, we demonstrated that the effect of ILK overexpression in the hippocampus was exerted via AKT-GSK3β pathway. Finally, we found that Fluoxetine, a selective serotonin reuptake inhibitor, could improve the impaired hippocampal neurogenesis and memory by enhancing ILK-AKT-GSK3β pathway activity in APP/PS1 mice. Thus, these findings demonstrated the effects of ILK on neurogenesis and memory recovery, suggesting that ILK is an important therapeutic target for AD prevention and treatment.

Abstract
BACKGROUND The molecular and genetic research showed the association between DFNA11 and mutations in MYO7A. This research aimed to identify a MYO7A mutation in a family with nonsyndromic autosomal dominant hearing loss. METHODS We have ascertained one large multigenerational Chinese family (Z029) with autosomal dominant late-onset progressive non-syndromic sensorineural hearing loss. Genome-wide linkage analysis of the family mapped the disease locus to the DFNA11 interval, where the MYO7A was considered as a candidate gene. Sequencing of the PCR products was carried out for each sample. One hundred and fifty one control subjects with normal hearing functions were also evaluated. RESULTS The pathogenic mutation (c.2011G>A) was identified in the family. This mutation co-segregated with hearing loss in this family. No mutation of MYO7A gene was found in the 151 controls. CONCLUSIONS The missense mutation of MYO7A is identified in the family displaying the pedigree consistent with DFNA11. We not only examined the clinical and genetic characteristics of the family, but also provided a basis for genetic counseling. We also summarized and analyzed the phenotypes and genotypes of all DFNA11 families, four of nine are Chinese families, suggesting that MYO7A mutations are not rare. Therefore, we should pay more attention to Chinese patients.

Abstract
Circular RNAs (circRNAs) are a type of endogenous non-coding RNAs which implicated in the progression of cancers. However, the role of circRNA_102231 in lung cancer remains unclear. Gene Expression Omnibus (GEO) datasets were used to investigate aberrantly expressed circRNAs in lung cancer. CircRNA_102231 expression in lung adenocarcinoma (LAC) tissues was dertermined by qRT-PCR. Furthermore, we explored the functions of circRNA_102231 on lung cancer cells progression. In the present study, circRNA_102231 was found to be one of the most significantly upregulated circRNAs in the GEO datasets analysis (GSE101586). QRT-PCR showed that circRNA_102231 expression was significantly upregulated in LAC tissues and associated with the advanced TNM stage, lymph node metastasis, and poor overall survival of lung cancer patients. The area under the receiver operating characteristic curve (ROC) was 0.897. in addition, function assays showed that circRNA_102231 inhibition significantly suppressed lung cancer cells proliferation and invasion ability in vitro. In conclusion, our study demonstrated that circRNA_102231 could act as a potential biomarker and therapeutic target for lung cancer patients.

Abstract
Background Hippo/YAP pathway is known to be important for development, growth and organogenesis, and dysregulation of this pathway leads to tumor progression. We and others find that YAP is up-regulated in pancreatic ductal adenocarcinoma (PDAC) and associated with worse prognosis of patients. Activated pancreatic stellate cells (PSCs) forming the components of microenvironment that enhance pancreatic cancer cells (PCs) invasiveness and malignance. However, the role and mechanism of YAP in PDAC tumor-stromal interaction is largely unknown. Methods The expression of YAP in Pancreatic cancer cell lines and PDAC samples was examined by Western blot and IHC. The biological role of YAP on cancer cell proliferation, epithelial-mesenchymal transition (EMT) and invasion were evaluated by MTT, Quantitative real-time PCR analysis, Western blot analysis and invasion assay. The effect of YAP on PSC activation was evaluated by PC-PSC co-culture conditions and xenograft PDAC mouse model. Results Firstly, knockdown of YAP inhibits PDAC cell proliferation and invasion in vitro. In addition, YAP modulates the PC and PSC interaction via reducing the production of connective tissue growth factor (CTGF) from PCs, inhibits paracrine-mediated PSC activation under PC-PSC co-culture conditions and in turn disrupts TGF-β1-mediated tumor-stromal interactions. Lastly, inhibiting YAP expression prevents tumor growth and suppresses desmoplastic reaction in vivo. Conclusions These results demonstrate that YAP contributes to the proliferation and invasion of PC and the activation of PSC via tumor-stromal interactions and that targeting YAP may be a promising therapeutic strategy for PDAC treatment.

Abstract
Pancreatic cancer represents one of the most lethal human cancers. Investigation of the effective targeting to the tumor cells is essential for both primary tumors and metastases. Tumor specific cytotoxic T lymphocytes (CTLs) have recently been considered to be the attractive vehicles for delivering therapeutic agents toward various tumor diseases. This study was to explore the distribution pattern of CTL carrying the lentiviral vectors with the characteristic of adenoviral E1 gene under the control of the cell activation-dependent CD40 ligand promoter (Lenti/hCD40L/E1AB). Following transduction with adenoviral particles containing chimeric type 5 and type 35 fiber proteins (Ad5/35-TRAIL), these CTLs produced infectious virus when exposed to SW1990 cells. We found that the novel CTL harboring Lenti/hCD40L/E1AB and Ad5/35-TRAIL inhibited pancreatic cancer cell growth and angiogenesis in vitro and in vivo. Furthermore, Ad5/35-TRAIL transduced CTL induced significant apoptosis in pancreatic carcinoma cell lines and upregulated IFN-gamma (IFN-γ) secretion of CTLs. Importantly, Ad5/35-TRAIL transduced CTLs had no inhibitory effect on normal cells. Thus, the novel CTLs may be safe and feasible for the development of gene therapy approaches to pancreatic carcinoma.

Abstract
MicroRNA (miR) signatures may aid the diagnosis and prediction of cancer; therefore, miRs associated with the prognosis of esophageal squamous cell carcinoma (ESCC) were screened. miR‑sequencing (seq) and mRNA‑seq data from early‑stage ESCC samples were downloaded from The Cancer Genome Atlas (TCGA) database, and samples from subjects with a >6‑month survival time were assessed with Cox regression analysis for prognosis‑associated miRs. A further two miR expression datasets of ESCC samples, GSE43732 and GSE13937, were downloaded from the Gene Expression Omnibus database. Common miRs between prognosis‑associated miRs, and miRs in the GSE43732 and GSE13937, datasets were used for risk score calculations for each sample, and median risk scores were applied for the stratification of low‑ and high‑risk samples. A prognostic scoring system of signature miRs was subsequently constructed and used for survival analysis for low‑ and high‑risk samples. Differentially‑expressed genes (DEGs) corresponding to all miRs were screened and functional annotation was performed. A total of 34 prognostic miRs were screened and a scoring system was created using 10 signature miRs (hsa‑miR‑140, ‑33b, ‑34b, ‑144, ‑486, ‑214, ‑129‑2, ‑374a and ‑412). Using this system, low‑risk samples were identified to be associated with longer survival compared with high‑risk samples in the TCGA and GSE43732 datasets. Age, alcohol and tobacco use, and radiotherapy were prognostic factors for samples with different risk scores and the same clinical features. There were 168 DEGs, and the top 20 risk scores positively‑correlated and the top 20 risk scores negatively‑correlated DEGs were significantly enriched for six and 10 functional terms, respectively. 'Tight junction' and 'melanogenesis' were two significantly enriched pathways of DEGs. miR‑214, miR‑129‑2, miR‑37a and miR‑486 may predict ESCC patient survival, although further studies to validate this hypothesis are required.

Abstract
Background Pancreatic cancer is a lethal disease in part because of its potential for aggressive invasion and metastasis. Lipoxin A4 (LXA4) is one of the metabolites that is derived from arachidonic acid and that is catalyzed by 15-lipoxygenase (15-LOX), and it has recently been reported to exhibit anti-cancer effects. However, the role of LXA4 in pancreatic cancer remains to be elucidated. Methods Pancreatic cell lines were treated with vehicle or LXA4, and the invasive capacity was then assessed by Transwell assays. The expression of epithelial and mesenchymal markers was determined by western blotting and immunofluorescence. Anti-TGF-β1 neutralizing antibody and exogenous recombinant human TGF-β1 (rhTGF-β1) were used to study the effect of LXA4 on the TGF-β signaling. A liver metastasis model was applied to investigate the effect of LXA4 in vivo. The correlation between the Lipoxin effect score (LES) and the clinical-pathological features of pancreatic cancer was also analyzed. Results We found that in patients with pancreatic cancer, low LES was correlated with aggressive metastatic potential. The LXA4 activity, which was mediated by the LXA4 receptor FPRL1, could significantly suppress invasion capacity and mesenchymal phenotypes. The expression and autocrine signaling pathway activity of TGF-β1 were also downregulated by LXA4. In the liver metastasis model in nude mice, the stable analog of LXA4, BML-111, could inhibit the metastasis of pancreatic cancer cells. Conclusion Our results demonstrated that LXA4 could reverse mesenchymal phenotypes, which attenuated invasion and metastasis via the inhibition of autocrine TGF-β1 signaling in pancreatic cancer, which may provide a new strategy to prevent the metastasis of pancreatic cancer.

Abstract
The present study was conducted to investigate the prognosis and survival of patients with locally advanced gastric cancer who underwent distal subtotal gastrectomy with modified D2 (D1+) and D2 lymphadenectomy, under 70 years of age. The five-year overall survival rates of 390 patients were compared between those receiving D1+ and D2 lymphadenectomy. Univariate and multivariate analyses were used to identify factors that correlated with prognosis and lymph node metastasis. Tumor size (P=0.039), pT stage (P=0.011), pN stage (P<0.001), and lymphadenectomy (P=0.004) were identified as independent prognostic factors. Furthermore, tumor size (P=0.022), pT stage (P=0.012), and lymphadenectomy (P=0.028) were proven as independent factors predicting lymph node metastasis. In conclusion, cancers of larger size, higher pT stage, and with D1+ lymphadenectomy had a higher risk of lymph node metastasis. Standard D2 lymphadenectomy removes sufficient lymph nodes to improve staging accuracy and survival. Therefore, D2 lymphanectomy is recommended in distal subtotal gastrectomy for locally advanced gastric cancer, especially for cancers of larger size and higher pT stage.

Abstract
Myocardial ischemia/reperfusion (I/R) injury is usually caused by resuscitation following cardiac arrest. The aim of the present study was to investigate the influence of sevoflurane postconditioning on the myocardial ultrastructure induced by cardiac arrest and successful resuscitation in mature rabbits. A total of 32 rabbits were randomly and equally divided into an I/R group (I/R group), a hypothermia group (H group), a sevoflurane postconditioning group (S group), and hypothermia plus sevoflurane postconditioning group (H + S group). Interleukin (IL)-8 and IL-10 levels in blood were evaluated at four different time points (1 h pre-ischemia: T1; 1, 2 and 3 h after reperfusion: T2, T3 and T4, respectively). The myocardial ultrastructure was evaluated by microscope after the rabbits were scarified. Plasma levels of IL-8 and IL-10 increased in all of the groups from T2. However, compared with the I/R group from T3 and T4, downregulation of IL-8 was significant in the S and H + S groups (P<0.05), and the result of intra-group comparison demonstrated that the level of serum IL-8 was the lowest in the H + S group (P<0.05). By contrast, upregulation of IL-10 was significantly higher in the S and H + S groups (P<0.05), particularly in the H + S group. Notably, ultrastructure damage of the myocardium was significantly lighter, and the structural integrity of the myocardium in the H + S group was better when compared with that of the S group. Thus, sevoflurane postconditioning plus hypothermia protected the myocardial ultrastructure following cardiopulmonary resuscitation by suppressing inflammatory effects.

Abstract
BACKGROUND Infections in the oral and maxillofacial region can sometimes extend beyond the oral cavity, with serious consequences. Most oral infections are odontogenic, occurring through the root apex of the tooth or the periodontal pocket. It thus makes sense that edentulous patients have a much lower risk of oral bacterial infection. For this reason, while there are many reports on systemic infections caused by oral infections, few of these describe such infections in edentulous patients. CASE PRESENTATION We present a case of oral and maxillofacial cellulitis followed by sepsis due to Streptococcus pyogenes infection in an 89-year-old Japanese edentulous woman. S. pyogenes was detected in the wound of left maxilla and the blood sample. S. pyogenes has been reported to be one of the most common and influential aerobic bacteria associated with deep neck infection and subsequent systemic infection. Left maxillary sinusitis was observed, and this could be the origin of the S. pyogenes infection. S. pyogenes derived from the sinusitis and leaked to the oral cavity might have caused systemic infection through wounding of the oral mucosa. Fortunately, intensive antibiotic therapy was effective, and the patient recovered without any surgical procedures. CONCLUSIONS We experienced a rare case of oral and maxillofacial cellulitis followed by sepsis due to a Streptococcus pyogenes infection in an old edentulous woman. This result indicated that, while edentulous patients are considered to have no risk of odontogenic infection, they still carry a risk of bacterial infection.

Abstract
Digenic Connexin26 (Cx26, GJB2) and Cx30 (GJB6) heterozygous mutations are the second most frequent cause of recessive deafness in humans. However, the underlying deafness mechanism remains unclear. In this study, we created different double Cx26 and Cx30 heterozygous (Cx26+/-/Cx30+/-) mouse models to investigate the underlying pathological changes and deafness mechanism. We found that double Cx26+/-/Cx30+/- heterozygous mice had hearing loss. Endocochlear potential (EP), which is a driving force for hair cells producing auditory receptor current, was reduced. However, unlike Cx26 homozygous knockout (Cx26-/-) mice, the cochlea in Cx26+/-/Cx30+/- mice displayed normal development and had no apparent hair cell degeneration. Gap junctions (GJs) in the cochlea form two independent networks: the epithelial cell GJ network in the organ of Corti and the connective tissue GJ network in the cochlear lateral wall. We further found that double heterozygous deletion of Cx26 and Cx30 in the epithelial cells did not reduce EP and had normal hearing, suggesting that Cx26+/-/Cx30+/- may mainly impair gap junctional functions in the cochlear lateral wall and lead to EP reduction and hearing loss. Most of Cx26 and Cx30 in the cochlear lateral wall co-expressed in the same gap junctional plaques. Moreover, sole Cx26+/- or Cx30+/- heterozygous mice had no hearing loss. These data further suggest that digenic Cx26 and Cx30 mutations may impair heterozygous coupling of Cx26 and Cx30 in the cochlear lateral wall to reduce EP, thereby leading to hearing loss.

Abstract
BACKGROUND Ki67 is a good marker of cell proliferation in a variety of tumors. High ki67 levels are usually associated with poor prognosis. However, the relationship between Ki67 expression and the risk of malignancy of gastrointestinal stromal tumors (GISTs) is still poorly defined. The current meta-analysis was initiated to address this issue. METHODS Studies reporting Ki67 expression and the risk of malignancy in GIST were found by searching Cochrane Library, PubMed, Medline, and Embase until October 31, 2016. A total of 9 studies involving 982 patients were included. Pooled odds ratio (OR) estimates and 95% confidence intervals (CIs) were calculated using a fixed-effect model. RESULTS Meta-analysis showed no significant difference in the incidence of Ki67 overexpression between the very low NIH group and the low NIH group (OR: 0.66, 95% CI: 0.25-1.76; P = .41, Pheterogeneity = .25). However, the incidence of Ki67 overexpression gradually increased from the low NIH group to the high NIH group (OR: 0.46, 95% CI: 0.27-0.80; P = .005, Pheterogeneity = .13) and (OR: 0.22, 95% CI: 0.15-0.34; P < .00001, Pheterogeneity = .33). CONCLUSIONS There were more GIST patients with Ki67 overexpression in the intermediate and high NIH groups than in the low NIH group. Ki67 overexpression may be a useful marker of the risk of malignant GIST transformation.

Abstract
Mutations of Connexin 26 (Cx26, GJB2), which is a predominant gap junction isoform in the cochlea, can induce high incidence of nonsyndromic hearing loss. We previously found that targeted-deletion of Cx26 in supporting Deiters cells and outer pillar cells in the cochlea can influence outer hair cell (OHC) electromotility and reduce active cochlear amplification leading to hearing loss, even though there are no gap junction connexin expressions in the auditory sensory hair cells. Here, we further report that hearing loss and the reduction of active amplification in the Cx26 targeted-deletion mice are progressive and different at high and low frequency regions, first occurring in the high frequency region and then progressively extending to the middle and low frequency regions with mouse age increased. The speed of hearing loss extending was fast in the basal high frequency region and slow in the apical low frequency region, showing a logarithmic function with mouse age. Before postnatal day 25, there were no significant hearing loss and the reduction of active cochlear amplification in the low frequency region. Hearing loss and the reduction of active cochlear amplification also had frequency difference, severe and large in the high frequency regions. These new data indicate that the effect of gap junction on active cochlear amplification is progressive, but, consistent with our previous report, exists in both high and low frequency regions in adulthood. These new data also suggest that cochlear gap junctions may have an important role in age-related hearing loss.

Abstract
The aim of this meta-analysis was to determine the feasibility of laparoscopic gastrectomy (LG) for elderly gastric cancer patients by comparing laparoscopic and conventional open gastrectomies (OG). Comprehensive search of the PubMed, EMBASE, and Cochrane Library databases revealed nine non-randomized controlled studies that compared LG and OG in elderly gastric cancer patients We then analyzed dichotomous or continuous parameters using odds ratios (ORs) or weighted mean differences (WMDs). Overall survival was estimated using hazard ratios (HRs) with a fixed effects or random effects model. We observed that the age distribution was similar between the LG and OG patient groups (WMD -0.22 95% CI, -1.26-0.82). LG patients experienced less blood loss (WMD -119.14 95% CI, -204.17--34.11) and had shorter hospital stays (WMD -3.48 95% CI, -5.41--1.56), but endured longer operation times (WMD 10.87 95% CI, 2.50-19.24). Postoperatively, LG patients exhibited lower incidences of postoperative morbidities (OR 0.59 95% CI, 0.43-0.79), surgery related morbidities (OR 0.58 95% CI, 0.41-0.81) and systemic morbidities (OR 0.56 95% CI, 0.38-0.82). We observed no differences between the LG and OG patient groups regarding anastomotic leakage (OR 0.69 95% CI, 0.34-1.41), mental disease (OR 0.72 95% CI, 0.37-1.41) and long term effects (HR 0.98 95% CI, 0.74-1.32). We therefore conclude that laparoscopic gastrectomy might be technically feasible for elderly gastric cancer patients.

Abstract
Background: The molecular genetic research showed the association between X-linked hearing loss and mutations in POU3F4. This research aimed to identify a POU3F4 mutation in a nonsyndromic X-linked recessive hearing loss family. Methods: A series of clinical evaluations including medical history, otologic examinations, family history, audiologic testing, and a high-resolution computed tomography scan were performed for each patient. Bidirectional sequencing was carried out for all polymerase chain reaction products of the samples. Moreover, 834 controls with normal hearing were also tested. Results: The pedigree showed X-linkage recessive inheritance pattern, and pathogenic mutation (c.499C>T) was identified in the proband and his family member, which led to a premature termination prior to the entire POU domains. This mutation co-segregated with hearing loss in this family. No mutation of POU3F4 gene was found in 834 controls. Conclusions: A nonsense mutation is identified in a family displaying the pedigree consistent with X-linked recessive pattern in POU3F4 gene. In addition, we may provide molecular diagnosis and genetic counseling for this family.

Abstract
Secretory carcinoma (SC), previously described as mammary analogue secretory carcinoma (MASC), is a recently described salivary gland tumor which morphologically resembles mammary secretory carcinoma. The first description of SC/MASC, reported by Skálová et al. in 2010, was as a rare salivary carcinoma imitating secretory carcinoma of the breast. SC/MASC is a unique salivary gland tumor with morphological overlap with acinic cell carcinoma (AciCC), mucoepidermoid carcinoma (MEC), and adenocarcinoma not otherwise specified (ADC-NOS). SC/MASC shares similar clinicopathological features with AciCC. As a critical difference between SC/MASC and AciCC, SC/MASC characteristically has the chromosomal translocation t(12;15)(p13;q25) which leads to a fusion gene between the ETV6 gene on chromosome 12 and the NTRK3 gene on chromosome 15. This genetic background is an important differential diagnostic finding for excluding other salivary gland tumors and may be a critical factor determining the prognosis for patients with SC/MASC. Research in recent years has provided a large body of new data on SC/MASC and suggests the possibility that the ETV6-NTRK3 translocation could be a therapeutic target. Here, we review the morphological and clinicopathological features of SC/MASC and discuss new directions for therapy.

Abstract
MicroRNAs are involved in the initiation and progression of pancreatic cancer. In this study, we showed that miR-221/222 is overexpressed in pancreatic cancer. MiR-221/222 overexpression significantly promoted pancreatic cancer cell proliferation and invasion while inhibiting apoptosis. The expression of the matrix metalloproteinases (MMPs) MMP-2 and MMP-9 was increased in miR-221/222 mimic-transfected pancreatic cancer cells. Validation experiments identified TIMP-2 as a direct target of miR-221/222. These data indicate that overexpressed miR-221/222 may play an oncogenic role in pancreatic cancer by inducing the expression of MMP-2 and MMP-9, thus leading to cancer cell invasion.

Abstract
Primary esophageal or gastric melanoma is a very rare disease with early metastasis. Due to its atypical symptom and less efficiency of chemotherapy and radiotherapy, the prognosis of esophageal or gastric melanoma is still very poor. Surgical resection remains the preferential treatment for esophageal or gastric melanoma. Here we present an extremely rare case of primary advanced esophago-gastric melanoma. Debulking surgery was performed without chemotherapy or radiotherapy. However, abdominal recurrence and hepatic metastases were found within one month by a postoperative follow-up computed tomography. Three and a half months after surgical resection, the patient died of extensive abdominal metastasis.

Abstract
Auditory neuropathy spectrum disorder (ANSD) is one of the most common diseases leading to hearing and speech communication barriers in infants and young children. The OTOF gene is the first gene identified for autosomal recessive non-syndromic ANSD, and patients with OTOF mutations have shown marked improvement of auditory functions from the cochlear implantation, but the true involvement of OTOF mutations in Chinese ANSD patients is still unknown which precludes the effective management of this disease. Here, we investigated the contribution of OTOF mutations to congenital ANSD patients in China. In all, 37 infants and young Children with ANSD were screened for all the exons of OTOF gene, of them 34 patients had no neonatal risk factors who were considered as congenital ANSD. The clinical manifestation and audiometric features were also investigated and compared in patients with and without OTOF mutations. In all, 14 of these subjects were shown to carry two or three mutant alleles of OTOF with the high frequency of 41.2% in congenital ANSD patients. In total, 15 novel pathogenic mutations and 10 reported mutations were identified. Our results confirmed that mutations in OTOF gene were a major cause of congenital ANSD in China. Identification of OTOF mutations can facilitate diagnosis, clinical intervention and counseling for congenital ANSD.

Tracking the Correlation Between CpG Island Methylator Phenotype and Other Molecular Features and Clinicopathological Features in Human Colorectal Cancers: A Systematic Review and Meta-Analysis.

Abstract
Objectives: The controversy of CpG island methylator phenotype (CIMP) in colorectal cancers (CRCs) persists, despite many studies that have been conducted on its correlation with molecular and clinicopathological features. To drive a more precise estimate of the strength of this postulated relationship, a meta-analysis was performed. Methods: A comprehensive search for studies reporting molecular and clinicopathological features of CRCs stratified by CIMP was performed within the PubMed, EMBASE, and Cochrane Library. CIMP was defined by either one of the three panels of gene-specific CIMP markers (Weisenberger panel, classic panel, or a mixture panel of the previous two) or the genome-wide DNA methylation profile. The associations of CIMP with outcome parameters were estimated using odds ratio (OR) or weighted mean difference (WMD) or hazard ratios (HRs) with 95% confidence interval (CI) for each study using a fixed effects or random effects model. Results: A total of 29 studies involving 9,393 CRC patients were included for analysis. We observed more BRAF mutations (OR 34.87; 95% CI, 22.49–54.06) and microsatellite instability (MSI) (OR 12.85 95% CI, 8.84–18.68) in CIMP-positive vs. -negative CRCs, whereas KRAS mutations were less frequent (OR 0.47; 95% CI, 0.30–0.75). Subgroup analysis showed that only the genome-wide methylation profile-defined CIMP subset encompassed all BRAF-mutated CRCs. As expected, CIMP-positive CRCs displayed significant associations with female (OR 0.64; 95% CI, 0.56–0.72), older age at diagnosis (WMD 2.77; 95% CI, 1.15–4.38), proximal location (OR 6.91; 95% CI, 5.17–9.23), mucinous histology (OR 3.81; 95% CI, 2.93–4.95), and poor differentiation (OR 4.22; 95% CI, 2.52–7.08). Although CIMP did not show a correlation with tumor stage (OR 1.10; 95% CI, 0.82–1.46), it was associated with shorter overall survival (HR 1.73; 95% CI, 1.27–2.37). Conclusions: The meta-analysis highlights that CIMP-positive CRCs take their own molecular feature, especially overlapping with BRAF mutations, and clinicopathological features and worse prognosis from CIMP-negative CRCs, suggesting CIMP could be used as an independent prognostic marker for CRCs.
