ABSTRACT

OBJECTIVES: The role of Epoxide Hydrolase-4 (EPHX4), a member of epoxide hydrolase family, has not been investigated in cancer. The purpose of this article is to explore the application value of EPHX4 in laryngeal cancer and its relationship with immune infiltration. METHODS: We observed that EPHX4 expression and its survival assays in laryngeal cancer specimens based on The Cancer Genome Atlas (TCGA) cohorts. We also analyzed the correlation between immune cell infiltration levels and EPHX4 gene copy number in laryngeal cancer. Finally, we conducted in vitro assay to evaluate the functions of EPHX4 in laryngeal cancer cell line. RESULTS: EPHX4 is highly expressed in laryngeal cancer specimens and has a poor prognosis. EPHX4 related immune cell analysis showed that it participated in NK Natural killer cell mediated cytotoxicity. Finally, Cell experiments indicate that EPHX4 could promote laryngeal cancer cell line proliferation, colony formation and invasion. CONCLUSIONS: Our research results suggest that EPHX4 may be a potential immunotherapy target for laryngeal cancer. The nominated immune signature is a helpful and promising prognostic indicator in laryngeal cancer. LEVELS OF EVIDENCE: Level 3.

ABSTRACT

Pea (Pisum sativum L.) is the fourth leading legume crop in the world, and its demand is increasing. In this study, the morphological characteristics (seed shape, seed surface, seed coat color, hilum color, cotyledon color, 100-seed weight and color values), total phenolic content (TPC), total flavonoid content (TFC), 2,2-azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) free radical scavenging capacity and ferric reducing antioxidant power (FRAP) of 75 pea cultivars were investigated. Results showed rich genetic diversity and a wide range of phenolic contents and antioxidant activities. Sixteen varieties enriched with phenolic contents and high antioxidant activities were screened out. A significant correlation was reported among color values, TPC, TFC, ABTS and FRAP. Principal component analysis (PCA) extracted four principal components with a total cumulative contribution of 81.29%. Hierarchical cluster analysis based on the four extracted principal components resulted in a dendrogram dividing the peas into three groups. In addition, dark pea seeds have potential as a functional food in addition to their traditional role in providing dietary protein and fibre. This study provided a scientific basis for the breeding of pea varieties, development of new products and improvement of pea resource utilization.(AU)


A ervilha (Pisum sativum L.) é a quarta cultura de leguminosas líder no mundo e sua demanda está aumentando. Neste estudo, as características morfológicas (forma da semente, superfície da semente, cor da casca, cor do hilo, cor do cotilédone, peso de 100 sementes e valores de cor), teor fenólico total (TPC), teor de flavonóides totais (TFC), 2,2. A capacidade de eliminação de radicais livres de ‘-azinobis- (3-etilbenzotiazolino-6-sulfonato) (ABTS) e o poder antioxidante redutor de ferro (FRAP) de 75 cultivares de ervilha foram investigados. Os resultados mostraram rica diversidade genética e uma ampla gama de conteúdos fenólicos e atividades antioxidantes. Dezesseis variedades enriquecidas com conteúdo fenólico e alta atividade antioxidante foram descartadas. Uma correlação significativa foi encontrada entre os valores de cores, TPC, TFC, ABTS e FRAP. A análise de componentes principais (PCA) extraiu quatro componentes principais com uma contribuição total acumulada de 81, 29%. A análise hierárquica de agrupamento foi baseada nos quatro componentes principais extraídos resultou em um dendrograma dividindo as ervilhas em três grupos. Assim, as sementes de ervilha escura têm potencial como alimento funcional, além de seu papel tradicional no fornecimento de proteína e fibra dietética. Este estudo fornece uma base científica para a criação de variedades de ervilha, desenvolvimento de novos produtos e melhoria da utilização de recursos de ervilha.(AU)
