Yuan Z, Wang Y, Xu S, Zhang M, Tang J. Construction of a prognostic model for colon cancer by combining endoplasmic reticulum stress responsive genes. J Proteomics 2024; 309:105284. [PMID: 39159861 DOI: 10.1016/j.jprot.2024.105284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 07/31/2024] [Accepted: 08/15/2024] [Indexed: 08/21/2024]
Abstract
Endoplasmic reticulum stress may affect the occurrence and development of cancer. However, its effect on the prognosis of colon cancer (CC) patients is not clear yet. Herein, based on TCGA database, we screened 15 endoplasmic reticulum stress responsive genes (ERSRGs) associated with the prognosis of CC patients by Cox regression. By LASSO and multivariate Cox regression analyses, a prognostic risk assessment model involving 12 genes (DNAJB2, EIF4A1, YPEL4, COQ10A, IRX3, ASPHD1, NTRK2, TRIM39, XBP1, GRIN2B, LRRC59, and RORC) was built. The survival curves indicated that patients in the low-risk group had good prognosis. ROC curves demonstrated a good performance of this 12-gene prognostic model, and the Riskscore could be considered as an independent prognostic factor. Patients in low-risk group benefit more from immune checkpoint inhibitor and immune checkpoint blockade (ICB) treatment. Besides, the enrichment analysis suggested a remarkable difference in Ca2+ signaling in both groups. Finally, based on the cMAP database, we identified several potential drugs that could target high-risk groups, such as Dasatinib, GNF-2, Saracatinib, and WZ-1-84. To sum up, our research constructed an ERSRGs-characteristic prognostic model. The model is a promising biomarker for prediction of clinical outcomes and immune therapy response of CC patients. SIGNIFICANCE: Based on the transcriptomic data of colon cancer in the TCGA database, this study screens 12 endoplasmic reticulum stress-related genes (ERSRGs), including DNAJB2, EIF4A1, YPEL4, COQ10A, IRX3, ASPHD1, NTRK2, TRIM39, XBP1, asphD1, NTRK2. GRIN2B, LRRC59, and RORC, and a prognostic model was constructed. This model can be used as a predictor of prognosis and immunotherapy response in colon cancer patients. At the same time, model-based prediction of drugs can also be a potential option for colon cancer treatment in the future.

Abstract
YPEL2 is a member of the evolutionarily conserved YPEL family involved in cellular proliferation, mobility, differentiation, senescence, and death. However, the mechanism by which YPEL2, or YPEL proteins, mediates its effects is largely unknown. Proteins perform their functions in a network of proteins whose identities, amounts, and compositions change spatiotemporally in a lineage-specific manner in response to internal and external stimuli. Here, we explored interaction partners of YPEL2 by using dynamic TurboID-coupled mass spectrometry analyses to infer a function for the protein. Our results using inducible transgene expressions in COS7 cells indicate that proximity interaction partners of YPEL2 are mainly involved in RNA and mRNA metabolic processes, ribonucleoprotein complex biogenesis, regulation of gene silencing by miRNA, and cellular responses to stress. We showed that YPEL2 interacts with the RNA-binding protein ELAVL1 and the selective autophagy receptor SQSTM1. We also found that YPEL2 localizes stress granules in response to sodium arsenite, an oxidative stress inducer, which suggests that YPEL2 participates in stress granule-related processes. Establishing a point of departure in the delineation of structural/functional features of YPEL2, our results suggest that YPEL2 may be involved in stress surveillance mechanisms.

Mech Ageing Dev 2023; 211:111803. [PMID: 36963468 DOI: 10.1016/j.mad.2023.111803] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 03/14/2023] [Accepted: 03/20/2023] [Indexed: 03/26/2023]
Abstract
Yippee-like 2 (YPEL2) is expressed in tissues and organs enriched in vascular networks, such as heart, kidney, and lung. However, the roles of YPEL2 in endothelial cell senescence and the expression of YPEL2 in atherosclerotic plaques have not yet been investigated. Here, we report the essential role of YPEL2 in promoting senescence in human umbilical vein endothelial cells (HUVECs) and the upregulation of YPEL2 in human atherosclerotic plaques. YPEL2 was significantly upregulated in both H2O2-induced senescent HUVECs and the arteries of aged mice. Endothelial YPEL2 deficiency significantly decreased H2O2-increased senescence-associated beta-galactosidase (SA-β-gal) activity and reversed H2O2-inhibited cell viability. Additionally, endothelial YPEL2 knockdown reduced H2O2-promoted THP-1 cell adhesion to HUVECs and downregulated ICAM1 and VCAM1 expression. Mechanistic studies divulged that the p53/p21 pathway was involved in YPEL2-induced cellular senescence. We conclude that YPEL2 promotes cellular senescence via the p53/p21 pathway and that YPEL2 expression is elevated in atherosclerosis. These findings reveal YPEL2 as a potential therapeutic target in aging-associated diseases.

Abstract
Primary aldosteronism is the most common surgically curable form of hypertension. The sporadic forms of the disorder are usually caused by aldosterone overproduction from a unilateral adrenocortical aldosterone-producing adenoma or from bilateral adrenocortical hyperplasia. The main knowledge-advances in disease pathophysiology focus on pathogenic germline and somatic variants that drive the excess aldosterone production. Less clear are the molecular and cellular mechanisms that lead to an increased mass of the adrenal cortex. However, the combined application of transcriptomics, metabolomics, and epigenetics has achieved substantial insight into these processes and uncovered the evolving complexity of disrupted cell growth mechanisms in primary aldosteronism. In this review, we summarize and discuss recent progress in our understanding of mechanisms of cell death, and proliferation in the pathophysiology of primary aldosteronism.

Comprehensive analysis of the expression and prognosis of YPEL family members in clear cell renal cell cancer. Oncol Rep 2022; 48:134.

Abstract
The Yippee‑like (YPEL) gene family is composed of five members encoding a protein containing a zinc finger‑like metal‑binding domain. Due to its structure and location in cells, this domain is considered to be involved in cell multiplication and numerous types of cancer. However, the relationship between the protein and the prognosis of clear cell renal cell carcinoma (ccRCC) remains unknown. In the present study, using pan‑cancer data from the updated public database, the expression and correlation of YPEL genes in 33 types of cancer was systematically and comprehensively analyzed. The prognostic value of YPEL genes was evaluated by survival and Cox regression analysis. Considering the relationship between the tumor microenvironment and stem cell indices, the function of superoxide dismutase was evaluated. Tumor Immune Assessment Resources (TIMER) and CIBERSORT algorithm analysis were used to evaluate the correlation between YPEL genes and tumor immune infiltrating cells (TIICs). Furthermore, knockdown experiments of YPEL genes were developed to explore their effects on ccRCC cell proliferation, migration and invasion in ccRCC cell lines. Members of the YPEL family were differentially expressed in ccRCC. Increased expression levels of YPEL1, YPEL2, and YPEL5 were associated with improved overall survival and disease‑specific survival. TIMER and CIBERSORT analyses showed remarkable correlation between YPEL family members and TIICs. More importantly, the results of Cell Counting Kit‑8, EdU and Transwell assays revealed that the multiplication, migration and invasion abilities of ccRCC cell lines could be promoted by knocking out YPEL1, YPEL2 and YPEL5. In conclusion, the present study provided new insight into the different roles of YPEL1, YPEL2 and YPEL5 in ccRCC, and the relationship between YPEL1 and immune infiltration may offer new options for future clinical treatment.

Abstract
The endoplasmic reticulum (ER) plays a pivotal role in syntheses of proteins and steroid hormones and regulation of intracellular Ca2+ level. We aimed to investigate ER-associated genes in aldosterone-producing adenomas (APAs) and clarify their effect on aldosterone production. Microarray analysis targeting 288 ER-associated genes was conducted using nonfunctioning adrenocortical adenomas (n=5) and APAs (n=19). Immunohistochemistry and quantitative polymerase chain reaction analyses were performed with 13 nonfunctioning adrenocortical adenoma and 48 APA samples. Functional studies were performed with human adrenocortical carcinoma (HAC15) cells, some of which were genetically modified using lentiviruses. The ER chaperone calmegin (CLGN) was the most highly expressed ER-associated gene in APAs relative to nonfunctioning adrenocortical adenomas. Analysis with quantitative polymerase chain reaction revealed CLGN to be 9.5-fold upregulated in APAs relative to nonfunctioning adrenocortical adenomas. There were no differences among different APA genotypes affecting aldosterone production. Immunohistochemistry analysis revealed that CLGN was strongly expressed in APAs and aldosterone-producing cell clusters. Angiotensin II stimulation or KCNJ5 T158A overexpression in HAC15 cells did not affect CLGN mRNA levels. CLGN overexpression in HAC15 cells increased aldosterone levels but did not stimulate CYP11B2 mRNA levels. Pathway and gene ontology analyses using RNA sequencing results showed that tRNA aminoacyl metabolism was the most enriched pathway in CLGN-overexpressing cells. CYP11B2 (aldosterone synthase) and HSD3B2 (3 beta-hydroxysteroid dehydrogenase/delta 5->4-isomerase type 2) protein expression were more abundant in CLGN-overexpressing cells. CLGN knockdown using CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/clustered regularly interspaced short palindromic repeat-associated 9) method in HAC15 cells that carry the KCNJ5 mutation did not affect aldosterone production. To summarize, CLGN was upregulated and associated with aldosterone production via translational regulation of CYP11B2 in APAs.

Abstract
INTRODUCTION A great deal of research has reported dysregulated expression of genes in systemic lupus erythematosus (SLE). This study aimed to analyze the lncRNA, miRNA and mRNA expression profile in SLE. MATERIAL AND METHODS RNA sequencing (RNA-seq) was used to detect the dysregulated RNAs in SLE. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways analysis were used to explore the function of these differentially expressed RNAs. RESULTS 2,353 lncRNAs, 827 mRNAs and 24 miRNAs were shown to be differentially expressed. GO analyses demonstrated that differentially expressed RNAs were enriched in a variety of molecular functions and biological processes including ribonucleotide, protein serine/threonine kinase activity function, regulation of B cell differentiation and others. KEGG pathway analyses revealed that differentially expressed mRNAs and lncRNAs were both enriched in FcγR-mediated phagocytosis, glycosaminoglycan biosynthesis-chondroitin sulfate/dermatan sulfate and glyoxylate and dicarboxylate metabolism pathways. The up-regulated miRNAs target genes were mainly enriched in the nuclear factor-κB (NF-κB) signaling pathway. The down-regulated miRNAs target genes were significantly enriched in metabolism of xenobiotics by cytochrome P450, bile secretion and terpenoid backbone biosynthesis pathways. CONCLUSIONS The current study reveals a comprehensive expression profile of lncRNAs, miRNAs and mRNAs and implies potential regulatory functions of these RNAs which are involved in the pathogenesis of SLE.

Abstract
Background The aim of this study was to investigate the effects of the expression of the YPEL3 gene in colonic adenocarcinoma cells grown in vitro and in colonic adenocarcinoma tissue from patients treated by surgical resection. Material/Methods The study included 108 patients diagnosed with primary colon cancer (Stages I to IV). The expression of the YPEL3 gene in colonic adenocarcinoma tissue and adjacent normal colonic tissue was detected by real-time quantitative PCR (qRT-PCR). The normal human colonic cell line CCD-1Co and colorectal adenocarcinoma cell lines HT-29 and HCT-8 were induced to overexpress the YPEL3 gene, and the effects on cell proliferation, migration, and invasion of colonic adenocarcinoma cells were investigated by the Cell Counting Kit-8 (CCK-8) assay, a transwell migration assay, and a transwell invasion assay, respectively. The effects of YPEL3 gene overexpression on the Wnt/β-catenin signaling pathway were detected by Western blot. Results Increased expression levels of the YPEL3 gene were present in colon adenocarcinoma tissue compared with adjacent normal colonic tissue in 98 of 108 patients. Overexpression of the YPEL3 gene inhibited the proliferation, migration, and invasion of the HT-29 and HCT-8 colonic adenocarcinoma cells, and inactivated the Wnt/β-catenin signaling pathway; treatment with the Wnt agonist, CAS 853220-52-7, reduced the inhibitory effects of YPEL3 overexpression on proliferation, migration, and invasion in vitro. Conclusions Expression of the YPEL3 gene was upregulated in human colonic adenocarcinoma tissue, and also inhibited the proliferation, migration, and invasion of colonic adenocarcinoma cells in vitro by inactivating the Wnt/β-catenin signaling pathway.

Abstract
Background Human Yippee-like-4 (YPEL4) is a member of the YPEL gene family. This family has been characterized as the first highly conserved family of genes coding for proteins that contain putative zinc-finger-like metal-binding domains, known as the Yippee domain. The YPEL family proteins are located at the centrosome adjacent to the nucleolus during interphase and mitotic apparatus during mitosis. Due to its subcellular localization, it is believed that YPEL4 may have an important role in the cell cycle and proliferation. Recent studies have shown the involvement of YPEL4 in biological processes such as the mitogen-activated protein kinase pathway and adrenal cell proliferation. Research on YPEL4 up to date also suggests that YPEL4 is a very important player in pulmonary diseases. Conclusions YPEL4 may regulate the mitogen-activated protein kinase signaling pathway to mediate adrenal cell proliferation; this molecule is also likely to be a very important player in pulmonary diseases. Although the function of YPEL4 is largely unknown, further research may substantiate the functional importance and underlying molecular processes in pulmonary and other diseases that would allow YPEL4 to become a therapeutic target.
