However, the molecular mechanism of PCa is still not completely clear. This study aimed to elucidate the important role of centromere protein A (CENPA) in PCa. Large numbers of bulk RNA sequencing (RNA‐seq) data and in‐house immunohistochemistry data were used in analysing the expression level of CENPA in PCa and metastatic PCa (MPCa) . Single‐cell RNA‐seq data was used to explore the expression status of CENPA in different prostate subpopulations. Enrichment analysis was employed to detect the function of CENPA in PCa. Clinicopathological parameters analysis was utilised in analysing the clinical value of CENPA. The results showed that CENPA was upregulated in PCa (standardised mean difference [SMD] = 0.83, p = 0.001) and MPCa (SMD = 0.61, p = 0.029) . CENPA was overexpressed in prostate cancer stem cells (CSCs) with androgen receptor (AR) negative compared to epithelial cells with AR positive. CENPA may influence the development of PCa through affecting cell cycle. Patients with nodal metastasis had higher expression level of CENPA. And patients with high CENPA expression had poor disease‐free survival. Taken together, Overexpression of CENPA may influence the development of PCa by regulating cell cycle and promoting metastasis.  \nAbbreviations: ADT, Androgen deprivation therapy.; AR, Androgen receptor; AUC, Area under curve; BP, Biological process; CC, Cellular component; ccRCC, Clear cell renal cell carcinoma; CENPA, Centromere protein; ChIP, Chromatin immunoprecipitation and DNA sequencing; CIN, chromosome instability; CSCs, Cancer stem cells; DEGs, Differentially expressed genes; GEO, Gene Expression Omnibus; IHC, Immunohistochemistry; IC50, half maximal inhibitory concentration; LPCa, Localised prostate cancer; MF, Molecular function; MPCa, Metastatic prostate cancer; PBS, Phosphate buf","cbCaiqdLJQw9GbyD","https://ap.wps.com/l/cbCaiqdLJQw9GbyD","pdf",2607392,14,"English","# Abstract\n# Abbreviations\n# Introduction","[{\"question\":\"What is the main purpose of this study on CENPA in prostate cancer?\",\"answer\":\"To elucidate the important role of centromere protein A (CENPA) in prostate cancer by integrating bulk RNA-seq, single-cell RNA-seq, enrichment analysis, and immunohistochemistry with clinicopathological evaluation.\"},{\"question\":\"How was CENPA expression assessed across prostate cancer stages and subpopulations?\",\"answer\":\"Bulk RNA sequencing and immunohistochemistry were used to analyze CENPA expression levels in PCa and metastatic PCa, while single-cell RNA-seq was used to examine CENPA expression across different prostate subpopulations, including cancer stem cells.\"},{\"question\":\"What clinical significance is associated with high CENPA expression?\",\"answer\":\"Higher CENPA expression correlated with nodal metastasis and worse disease-free survival, indicating potential value as a clinical marker and a contributor to disease progression through effects on cell cycle and metastasis.\"}]","High expression of centromere protein A and its molecular mechanism and clinical significance in prostate cancer: A study based on data mining and immunohistochemistry | PDF",1790229437,35]
