Abstract
Poly(ADP-ribose) glycohydrolase (PARG) as a main enzyme hydrolyzing poly(ADP-ribose) in eukaryotes, and its silencing can inhibit benzo(a)pyrene (BaP)-induced carcinogenesis. A thorough understanding of the mechanism of PARG silenced inhibition of BaP-induced carcinogenesis provides a new therapeutic target for the prevention and treatment of environmental hazard induced lung cancer. We found that the expression of several subtypes of the histone H2B was downregulated in BaP-induced carcinogenesis via PARG silencing as determined by label-free proteomics and confirmed by previous cell line- and mouse model-based studies. Analysis using the GEPIA2 online tool indicated that the transcription levels of H2BFS, HIST1H2BD, and HIST1H2BK in lung adenocarcinoma (LUAD) tissues and squamous cell lung carcinoma (LUSC) tissues were higher than those in normal lung tissues, while the transcription levels of HIST1H2BH in LUSC tissues were higher than those in normal lung tissues. The expression levels of HIST1H2BB, HIST1H2BH, and HIST1H2BL were significantly different in different lung cancer (LC) stages. Moreover, the expression of H2BFS, HIST1H2BD, HIST1H2BJ, HIST1H2BK, HIST1H2BL, HIST1H2BO, HIST2H2BE, and HIST2H2BF was positively correlated with that of PARG in LC tissues. Analysis of the Kaplan-Meier plotter database indicated that high H2B levels predicted low survival in all LC patients suggesting that H2B could be a new biomarker for determining the prognosis of the LC, and that its expression can be inhibited by PARG silencing in BaP-induced carcinogenesis.

Involvement of a novel regulatory cascade consisting of SET-H3K18ac/H3K27ac-53BP1 in Cr(VI)-induced malignant transformation of 16HBE cells. Toxicol Lett 2020; 339:70-77. [PMID: 33370592 DOI: 10.1016/j.toxlet.2020.12.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Revised: 12/09/2020] [Accepted: 12/21/2020] [Indexed: 12/20/2022]
Abstract
Hexavalent chromium (Cr(VI)) is a well-established human carcinogen with DNA damaging effects. Recently we established a Cr(VI)-induced malignant transformation model from a human bronchial epithelial (16HBE) cell line, and in the transformed (16HBE-T) cells reduced levels of 53BP1 (critical for DNA repair) and the acetylated histone H3K18/27 (H3K18/27ac) were observed. In 16HBE-T cells SET (a multifunctional protein) was elevated by Cr(VI) through quantitative proteomics analysis. In the present study, we further explore the involvement of SET in the H3K18/27ac/53BP1 cascade in the 16HBE-T model, primarily by knockdown of SET. Bioinformatic analysis of the differentially expressed proteins indicated enrichment in histone modifications, in which SET was a major regulator. In 16HBE cells SET expression was enhanced by Cr(VI) in a concentration- and exposure duration-dependent manner. In 16HBE-T cells, SET knockdown showed the following effects: reversal of H3K18/27ac and 53BP1 levels, enhanced enrichment H3K18/27ac in 53BP1's promotor region, increase rate of apoptosis and cell cycle G0/G1 arrest (with or without Cr(VI) treatment), and reduced colony-forming efficiency. Finally, In comparison with benzo(a)pyrene-transformed (malignant, 16HBE-B) cells from 16HBE where no changes in H3K18/27ac, 53BP1 or SET were observed, while the H3K18/27ac/53BP1 cascade was downregulated and SET upregulated in 16HBE-T cells, as compared with the parental 16HBE cells; thus the changes in 16HBE-T might be a specific effect of Cr(VI). In conclusion, our results suggest that SET may be involved in the malignant cell transformation, through inhibiting the H3K18/27ac/53BP1 cascade, at least in the 16HBE cell model.

DNA methylation-mediated repression of exosomal miR-652-5p expression promotes oesophageal squamous cell carcinoma aggressiveness by targeting PARG and VEGF pathways. PLoS Genet 2020; 16:e1008592.

Abstract
Exosomal microRNAs (miRNAs) have been recently shown to play vital regulatory and communication roles in cancers. In this study, we showed that the expression levels of miR-652-5p in tumour tissues and serum samples of oesophageal squamous cell carcinoma (OSCC) patients were lower compared to non-tumorous tissues and serum samples from healthy subjects, respectively. Decreased expression of miR-652-5p was correlated with TNM stages, lymph node metastasis, and short overall survival (OS). More frequent CpG sites hypermethylation in the upstream of miR-652-5p was found in OSCC tissues compared to adjacent normal tissues. Subsequently, miR-652-5p downregulation promoted the proliferation and metastasis of OSCC, and regulated cell cycle both in cells and in vivo. The dual-luciferase reporter assay confirmed that poly (ADP-ribose) glycohydrolase (PARG) and vascular endothelial growth factor A (VEGFA) were the direct targets of miR-652-5p. Moreover, the delivery of miR-652-5p agomir suppressed tumour growth and metastasis, and inhibited the protein expressions of PARG and VEGFA in nude mice. Taken together, our findings provide novel insight into the molecular mechanism underlying OSCC pathogenesis.

Regulation of Wnt Singaling Pathway by Poly (ADP-Ribose) Glycohydrolase (PARG) Silencing Suppresses Lung Cancer in Mice Induced by Benzo(a)pyrene Inhalation Exposure. Front Pharmacol 2019; 10:338. [PMID: 31130856 PMCID: PMC6509174 DOI: 10.3389/fphar.2019.00338] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2019] [Accepted: 03/19/2019] [Indexed: 01/03/2023] Open
Abstract
Benzo(a)pyrene (BaP) is a polycyclic aromatic hydrocarbon that specifically causes cancer and is widely distributed in the environment. Poly (ADP-ribosylation), as a key post-translational modification in BaP-induced carcinogenesis, is mainly catalyzed by poly (ADP-ribose) glycohydrolase (PARG) in eukaryotic organisms. Previously, it is found that PARG silencing can counteract BaP-induced carcinogenesis in vitro, but the mechanism remained unclear. In this study, we further examined this process in vivo by using heterozygous PARG knockout mice (PARG+/−). Wild-type and PARG+/− mice were individually treated with 0 or 10 μg/m3 BaP for 90 or 180 days by dynamic inhalation exposure. Pathological analysis of lung tissues showed that, with extended exposure time, carcinogenesis and injury in the lungs of WT mice was progressively worse; however, the injury was minimal and carcinogenesis was not detected in the lungs of PARG+/− mice. These results indicate that PARG gene silencing protects mice against lung cancer induced by BaP inhalation exposure. Furthermore, as the exposure time was extended, the protein phosphorylation level was down-regulated in WT mice, but up-regulated in PARG+/− mice. The relative expression of Wnt2b and Wnt5b mRNA in WT mice were significantly higher than those in the control group, but there was no significant difference in PARG+/− mice. Meanwhile, the relative expression of Wnt2b and Wnt5b proteins, as assessed by immunohistochemistry and Western blot analysis, was significantly up-regulated by BaP in WT mice; while in PARG+/− mice it was not statistically affected. Our work provides initial evidence that PARG silencing suppresses BaP induced lung cancer and stabilizes the expression of Wnt ligands, PARG gene and Wnt ligands may provide new options for the diagnosis and treatment of lung cancer.

Abstract
The literature review presented here details recent research involving members of the poly(ADP-ribose) polymerase (PARP) family of proteins. Among the 17 recognized members of the family, the human enzyme PARP1 is the most extensively studied, resulting in a number of known biological and metabolic roles. This review is focused on the roles played by PARP enzymes in host-pathogen interactions and in diseases with an associated inflammatory response. In mammalian cells, several PARPs have specific roles in the antiviral response; this is perhaps best illustrated by PARP13, also termed the zinc finger antiviral protein (ZAP). Plant stress responses and immunity are also regulated by poly(ADP-ribosyl)ation. PARPs promote inflammatory responses by stimulating proinflammatory signal transduction pathways that lead to the expression of cytokines and cell adhesion molecules. Hence, PARP inhibitors show promise in the treatment of inflammatory disorders and conditions with an inflammatory component, such as diabetes, arthritis, and stroke. These functions are correlated with the biophysical characteristics of PARP family enzymes. This work is important in providing a comprehensive understanding of the molecular basis of pathogenesis and host responses, as well as in the identification of inhibitors. This is important because the identification of inhibitors has been shown to be effective in arresting the progression of disease.

Abstract
Poly (ADP-ribosylation) is a key post-translational modification (PTM), and poly (ADP-ribose) glycohydrolase (PARG) is the main enzyme that hydrolyzes poly (ADP-ribose) in eukaryotic organisms. Our previous findings suggested that knockdown of PARG attenuates benzo(a)pyrene (BaP) carcinogenesis. However, the mechanisms underlying PARG-mediated protective effects remain limited. In this study, the expression levels of histones were analyzed by Western blotting and immunofluorescence. Histone H2A levels were abnormally decreased by BaP-induced carcinogenesis, but were maintained by knockdown of PARG in the 16HBE human bronchial epithelial cell line. The interaction between poly (ADP-ribose) and H2A was confirmed by co-immunoprecipitation. PARG-related modifications in H2A were profiled by immune antibody enrichment coupled with mass spectrometry. H2AK5ac, H2AK9ac, H2AK13ac, H2A.ZK4K7K11ac, and H2AK9me were expressed in BaP-transformed 16HBE (BTC-16HBE) cells, but were not detectable in normal 16HBE or BaP-transformed 16HBE cells with knockdown of PARG (BTC-shPARG). Further verification by Western blotting indicated that H2AK9me was elevated in BTC-16HBE cells but decreased in BTC-shPARG cells. These findings suggest that knockdown of PARG protects against BaP-induced carcinogenesis in 16HBE cells by downregulating H2AK9me. Our in vivo studies confirmed that PARG silencing decreased H2AK9me levels, thereby countering the carcinogenic teratogenic effects induced by BaP.

Abstract
Tachyplesin I is a cationic peptide isolated from hemocytes of the horseshoe crab and its anti-tumor activity has been demonstrated in several tumor cells. However, there is limited information providing the global effects and mechanisms of tachyplesin I on glioblastoma multiforme (GBM). Here, by using two complementary proteomic strategies (2D-DIGE and dimethyl isotope labeling-based shotgun proteomics), we explored the effect of tachyplesin I on the proteome of gliomaspheres, a three-dimensional growth model formed by a GBM cell line U251. In total, the expression levels of 192 proteins were found to be significantly altered by tachyplesin I treatment. Gene ontology (GO) analysis revealed that many of them were cytoskeleton proteins and lysosomal acid hydrolases, and the mostly altered biological process was related to cellular metabolism, especially glycolysis. Moreover, we built protein-protein interaction network of these proteins and suggested the important role of DNA topoisomerase 2-alpha (TOP2A) in the signal-transduction cascade of tachyplesin I. In conclusion, we propose that tachyplesin I might down-regulate cathepsins in lysosomes and up-regulate TOP2A to inhibit migration and promote apoptosis in glioma, thus contribute to its anti-tumor function. Our results suggest tachyplesin I is a potential candidate for treatment of glioma.
