Also, histone modification is an epigenetic mechanism that plays a pivotal role in GC carcinogenesis. In this preliminary study, we aimed to describe the expression profiles of histone modification in the AG, IM, and GC patient groups. A total of 80 patients with AG (n = 27), IM (n = 25), and GC (n = 28) with an additional 20 control subjects were included in the study. Expression profiles of three histone phosphorylation genes (PAK1, NEK6, and AURKA) and five histone deacetylation genes (HDACs 1, 2, 3, 5, and 7) were examined based on the results of Real Time qPCR method. It was observed that AURKA and HDAC2 genes were significantly overexpressed in all groups compared to the control (P < 0.05). In GC patients, overexpression of HDAC2 gene was detected in the absence of metastasis, and overexpression of AURKA, HDAC2, and NEK6 genes was detected in the presence of metastasis. When cancer involvements were compared, significant overexpression of the HDAC2 gene was noted in overall and corpus involvements (P < 0.05). In addition, overexpression of AURKA, NEK6, HDAC1, and HDAC2 genes and underexpression of HDAC5 gene were detected in the antrum involvement (P < 0.05). In conclusion, decreased expression of HDAC5 in GC is reported for the first time in this study, while supporting the existing literature in AURKA, NEK6, HDAC1, and HDAC2 up regulations during GC development. © 2018, Springer Nature B.V.EnglishAdultAgedAurora Kinase ADisease ProgressionFemaleGastric MucosaGastritis, AtrophicGenetic VariationHelicobacter InfectionsHelicobacter pyloriHistone CodeHistone DeacetylasesHistonesHumansIntestinesMaleMetaplasiaMiddle AgedNIMA-Related Kinasesp21-Activated KinasesPreliminary DataRisk FactorsStomachStomach NeoplasmsTranscriptomeaurora A kinasehistonehistone deacetylase 1histone deacetylase 2histone deacetylase 3histone deacetylase 5p21 activated kinase 1AURKA protein, humanHDAC5 protein, humanhistonehistone deacetylaseNEK6 protein, humanNIMA related kinasep21 activated kinasePAK1 protein, humantranscriptomeadultArticleatrophic gastritisAURKA genecancer growthcancer patientcontrolled studyfemalegenegene expressiongene expression profilinggene overexpressionHDAC1 geneHDAC2 geneHDAC3 geneHDAC5 geneHDAC7 geneHelicobacter pylorihistone acetylationhistone modificationhumanintestine metaplasiamajor clinical studymalemetastasisNEK6 genePAK1 genepathogenesisstomach antrumstomach cancerupregulationageddisease exacerbationgenetic variationgeneticsHelicobacter infectionhistone codeintestinemetaplasiamiddle agedpathologypreliminary datarisk factorstomachstomach mucosastomach tumorArticle10.1007/s11033-018-4389-z
