PURPOSE: Pancreatic cysts are common and pose diagnostic and management challenges. Pancreatic cyst fluid markers have the potential to aid in the management of cysts with concerning imaging findings. Our aim was to evaluate cyst fluid methylated DNA markers for their accuracy for predicting the histologic grade of neoplastic pancreatic cysts. EXPERIMENTAL DESIGN: Pancreatic cyst fluid samples from 183 patients (29 discovery, 154 validation) aspirated after surgical resection were analyzed for methylated DNA at selected genes (SOX17, BNIP3, FOXE1, PTCHD2, SLIT2, EYA4 and SFRP1) using methylation-specific droplet-digital PCR (dd-QMSP)...

Genome-wide association studies have identified >50 common variants associated with kidney function, but these variants do not fully explain the variation in eGFR. We performed a two-stage meta-analysis of associations between genotypes from the Illumina exome array and eGFR on the basis of serum creatinine (eGFRcrea) among participants of European ancestry from the CKDGen Consortium (nStage1: 111,666; nStage2: 48,343). In single-variant analyses, we identified single nucleotide polymorphisms at seven new loci associated with eGFRcrea (PPM1J, EDEM3, ACP1, SPEG, EYA4, CYP1A1, and ATXN2L; PStage1<3...

Age-related hearing impairment (ARHI), one of the most common sensory disorders, can be mitigated, but not cured or eliminated. To identify genetic influences underlying ARHI, we conducted a genome-wide association study of ARHI in 6,527 cases and 45,882 controls among the non-Hispanic whites from the Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort. We identified two novel genome-wide significant SNPs: rs4932196 (odds ratio = 1.185, p = 4.0x10-11), 52Kb 3' of ISG20, which replicated in a meta-analysis of the other GERA race/ethnicity groups (1,025 cases, 12,388 controls, p = 0...

To understand the relationship between microRNAs and hearing loss and help clarify the causes of hereditary deafness, we studied the functions of miR-431 in cochleae. We first investigated the spatial-temporal expression profiles of miR-431 in spiral ganglion neurons (SGNs) in cochleae using real-time PCR and miRNA in situ hybridization. These studies showed that expression of miR-431 was high in SGNs in the cochleae of newborn mice, and decreased as development progressed. To test the functional effects of miR-431, we established miR-431 overexpressing transgenic (Tg) mice...

Eye absent homolog 4 (EYA4) was initially found as key gene in controlling eye development in Drosophila. We recently found that EYA4 was an independent prognostic factor in hepatocellular carcinoma. Its biological functions in malignancies remained unknown. The present study aimed at investigating its biological functions, molecular mechanisms and prognostic values in pancreatic ductal adenocarcinoma (PDAC). Overexpression of EYA4 in PDAC cells inhibited proliferation and invasion in vitro and tumor growth in vivo...

BACKGROUND: The acute myeloid leukemia 1 (AML1)-eight-twenty-one (ETO) fusion protein generated by the t(8;21)(q22;q22) translocation is considered to display a crucial role in leukemogenesis in AML. By focusing on the anti-leukemia effects of eyes absent 4 (EYA4) gene on AML cells, we investigated the biologic and molecular mechanism associated with AML1-ETO expressed in t(8;21) AML. METHODS: Qualitative polymerase chain reaction (PCR), quantitative reverse transcription PCR (RT-PCR), and Western blotting analysis were used to observe the mRNA and protein expression levels of EYA4 in cell lines...

REVIEW
Wenjun Xia, Fei Liu, Duan Ma
Hearing impairment is considered as the most prevalent impairment worldwide. Almost 600 million people in the world suffer from mild or moderate hearing impairment, an estimated 10% of the human population. Genetic factors play an important role in the pathogenesis of this disorder. Hereditary hearing loss is divided into syndromic hearing loss (associated with other anomalies) and non-syndromic hearing loss (not associated with other anomalies). Approximately 80% of genetic deafness is non-syndromic. On the basis of the frequency of hearing loss, hereditary non-syndromic hearing loss can be divided into high-, mid-, low-, and total-frequency hearing loss...

Five-year survival rates for oral squamous cell carcinoma (OSCC) have remained at a dismal 50% for the past several decades. Molecular analyses of premalignant tissues are a key means of identifying early foundational drivers of disease, which may be exploitable as biomarkers or therapeutic targets for improving disease outcomes. We previously identified EYA4 as frequently hypermethylated and silenced in premalignant disease based on an analysis of lesion-adjacent normal, dysplasia, and carcinoma in situ/squamous cell carcinoma tissues from the oral cavity...

BACKGROUND: E193, a heterozygous truncating mutation in the human transcription cofactor Eyes absent 4 (Eya4), causes hearing impairment followed by dilative cardiomyopathy. METHODS AND RESULTS: In this study, we first show Eya4 and E193 alter the expression of p27(kip1) in vitro, suggesting Eya4 is a negative regulator of p27. Next, we generated transgenic mice with cardiac-specific overexpression of Eya4 or E193. Luciferase and chromatin immunoprecipitation assays confirmed Eya4 and E193 bind and regulate p27 expression in a contradictory manner...

Genetic heterogeneity has made the identification of genes related to hearing impairment a challenge. In the absence of a clear phenotypic aetiology, recurrence risk estimates are often based on family segregation and may be imprecise. We profiled by oligonucleotide array-CGH patients presenting non-syndromic hearing loss with presumptive autosomal recessive (n = 50) or autosomal dominant (n = 50) patterns of inheritance. Rare copy number variants (CNVs) were detected in 12 probands; four of the detected CNVs comprised genes previously associated with hearing loss (POU4F3, EYA4, USH2A, BCAP31) and were considered causative, stressing the contribution of genomic imbalance to non-syndromic deafness...

The EYA4 gene encodes a 640-amino-acid protein that serves as a transcription factor. This protein contains a highly conserved Eya domain (eya-HR) and a variable domain (eya-VR). Mutations of this gene are known to cause postlingual and progressive sensorineural hearing loss, either as non-syndromic (DFNA10) or syndromic hearing loss, depending on the location of truncation of the mutant protein. Since our previous report, we have recruited 14 families segregating autosomal dominant moderate SNHL. A thorough medical history and physical examination including evaluation of heart problems ruled out any syndromic features in these families...

Autosomal dominant non-syndromic hearing loss is highly heterogeneous, and eyes absent 4 (EYA4) is a disease-causing gene. Most EYA4 mutations founded in the Eya-homologous region, however, no deafness causative missense mutation in variable region of EYA4 have previously been found. In this study, we identified a pathogenic missense mutation located in the variable region of the EYA4 gene for the first time in a four-generation Chinese family with 57 members. Whole-exome sequencing (WES) was performed on samples from one unaffected and two affected individuals to systematically search for deafness susceptibility genes, and the candidate mutations and the co-segregation of the phenotype were verified by polymerase chain reaction amplification and by Sanger sequencing in all of the family members...

EYA4 and GRHL2 encode transcription factors that play an important role in regulating many developmental stages. Since EYA4 and GRHL2 were identified as the transcription factors for the DFNA10 and DFNA28, 8 EYA4 mutations and 2 GRHL2 mutations have been reported worldwide. However, these genes have been reported in few studies of the Korean population. In this study, we performed a genetic analysis of EYA4 and GRHL2 in 87 unrelated Korean patients with autosomal dominant non-syndromic hearing loss (NSHL). A total of 4 genetic variants in the EYA4 gene were identified, including the 2 nonsense mutations p...
