Food Chem Toxicol 2020; 149:111938. [PMID: 33348051 DOI: 10.1016/j.fct.2020.111938] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Revised: 12/09/2020] [Accepted: 12/15/2020] [Indexed: 12/31/2022]
Abstract
The objective of this study was to use isobaric tags for relative and absolute quantitation (iTRAQ) proteomic technology to systematically analyze the hepatotoxic mechanism of aflatoxin B1 (AFB1) and its prevention by Se in broilers. Four groups of day-old broilers were allocated into a 2 × 2 factorial design trial that fed a Se-deficient based diet (BD) or the BD + 1.0 mg AFB1/kg, 0.3 mg Se/kg, or 1.0 mg AFB1/kg plus 0.3 mg Se/kg for 3 wk. Dietary AFB1 increased serum ALT and decreased total protein and albumin concentrations, and induced hepatic histopathological lesions in Se adequate groups. Notably, Se deficiency exacerbated these AFB1-induced changes. Furthermore, Se deficiency reduced hepatic glutathione peroxidase but increased thioredoxin reductase and glutathione S-transferase activities and 8-hydroxydeoxyguanosine concentration in AFB1 administrated groups. Moreover, AFB1 dysregulated 261 co-differentially expressed proteins (DEPs) in both Se adequate and deficiency diets, and Se deficiency dysregulated 64 DEPs in AFB1 administrated diets. These DEPs are mainly related to phase I and II metabolizing enzymes, heat shock proteins, DNA repair, fatty acid metabolism and apoptosis. The in vitro study has verified that aldo-keto reductase family1, member10 plays an important role in AFB1-induced hepatotoxicity and Se-mediated detoxification of AFB1 in a chicken leghorn male hepatoma cells. Conclusively, this study has analyzed the hepatic proteome response to dietary AFB1 and Se, and thus shed new light on the mechanisms of hepatotoxicity of AFB1 and its detoxification by Se in broilers.

[PMID: 30177619 PMCID: PMC6162743 DOI: 10.3390/cancers10090305] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 08/31/2018] [Accepted: 08/31/2018] [Indexed: 01/06/2023] Open
Abstract
Cancer stem cells (CSCs) represent a sub-population of cancer cells with the ability to regulate stemness-associated properties which are specifically responsible for unlimited growth of cancers, generation of diverse cancer cells in differentiated state and resistance to existing chemotherapy and radiotherapy. Even though, current therapies destroy majority of cancer cells, it is believed to leave CSCs without eradicating which may be the conceptualization for chemoresistance and radio-resistance. Reactive oxygen species (ROS) maintain stem cells and regulate the stemness-associated properties of cancers. Beyond the maximum limit, ROS can damage cellular functions of cancers by subjecting them to oxidative stress. Thus, maintenance of ROS level plays an important role in cancers to regulate stemness-associated properties. Peroxiredoxin II (Prx II) is a member of peroxiredoxin antioxidant enzyme family which considers as a regulator of ROS in cellular environments by modulating redox status to maintain CSC phenotype and stemness properties. Prx II has cell type-dependent expression in various types of cancer cells and overexpression or silenced expression of Prx II in cancers is associated with stem cell phenotype and stemness-associated properties via activation or deactivation of various signaling pathways. In this review, we summarized available studies on Prx II expression in cancers and the mechanisms by which Prx II takes parts to regulate CSCs and stemness-associated properties. We further discussed the potential therapeutic effects of altering Prx II expression in cancers for better anticancer strategies by sensitizing cancer cells and stem cells to oxidative stress and inhibiting stemness-associated properties.

Abstract
Objective(s): Ranking as the sixth commonest cancer, esophageal squamous cell carcinoma (ESCC) represents one of the leading causes of cancer death worldwide. One of the main reasons for the low survival of patients with esophageal cancer is its late diagnosis. Materials and Methods: We used proteomics approach to analyze ESCC tissues with the aim of a better understanding of the malignant mechanism and searching candidate protein biomarkers for early diagnosis of esophageal cancer. The differential protein expression between cancerous and normal esophageal tissues was investigated by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). Then proteins were identified by matrix-assisted laser desorption/ ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF-MS) and MASCOT web based search engine. Results: We reported 4 differentially expressed proteins involved in the pathological process of esophageal cancer, such as annexinA1 (ANXA1), peroxiredoxin-2 (PRDX2), transgelin (TAGLN) andactin-aortic smooth muscle (ACTA2). Conclusion: In this report we have introduced new potential biomarker (ACTA2). Moreover, our data confirmed some already known markers for EC in our region.

Abstract
Mycotoxins are secondary metabolites produced by many microfungi. Hitherto, over 300 mycotoxins with diverse structures have been identified. They contaminate most cereals and feedstuffs, which threaten human and animal health by exerting acute, sub-acute and chronic toxicological effects, with some considered as carcinogens. Many mycotoxins at low concentrations are able to induce the expression of cytochrome P450 and other enzymes implicated in the biotransformation and metabolization of mycotoxins in vivo and in vitro. Mycotoxins and their metabolites elicit different cellular disorders and adverse effects such as oxidative stress, inhibition of translation, DNA damage and apoptosis in host cells, thus causing various kinds of cytotoxicities. In this review, we summarize the biotransformation of mycotoxins in animal cells by CYP450 isoforms and other enzymes, their altered expression under mycotoxin exposure, and recent progress in mycotoxin cytotoxicity in different cell lines. Furthermore, we try to generalize the molecular mechanisms of mycotoxin effects in human and animal cells.

Abstract
Redox regulation in cancer stem cells (CSCs) is viewed as a good target for cancer therapy because redox status plays an important role in cancer stem-cell maintenance. Here, we investigated the role of Peroxiredoxin II (Prx II), an antioxidant enzyme, in association with maintenance of liver CSCs. Our study demonstrates that Prx II overexpressed in liver cancer cells has high potential for self-renewal activity. Prx II expression significantly corelated with expression of epithelial-cell adhesion molecules (EpCAM) and cytokerain 19 in liver cancer tissues of hepatocellular carcinoma (HCC) patients. Downregulation of Prx II in Huh7 cells with treatment of siRNA reduced expression of EpCAM and CD133 as well as Sox2 in accordance with increased ROS and apoptosis, which were reversed in Huh7-hPrx II cells. Huh7-hPrx II cells exhibited strong sphere-formation activity compared with mock cells. Vascular endothelial growth factor (VEGF) exposure enhanced sphere formation, cell-surface expression of EpCAM and CD133, and pSTAT3 along with activation of VEGF receptor 2 in Huh7-hPrx II cells. The result also emerged in Huh7-H-ras(G12V) and SK-HEP-1-H-ras(G12V) cells with high-level expression of Prx II. Prx II was involved in regulation of VEGF driving cancer stem cells through VEGFR-2/STAT3 signaling to upregulate Bmi1 and Sox2. In addition, knockdown of Prx II in Huh7-H-ras(G12V) cells showed significant reduction in cell migration in vitro and in tumorigenic potential in vivo. Taken together, all the results demonstrated that Prx II plays a key role in the CSC self-renewal of HCC cells through redox regulation. Stem Cells 2016;34:1188-1197.

Abstract
The aim of the present study was to determine key pathways and genes involved in the pathogenesis of hepatocellular carcinoma (HCC) through bioinformatic analyses of HCC microarray data based on cross-species comparison. Microarray data of gene expression in HCC in different species were analyzed using gene set enrichment analysis (GSEA) and meta-analysis. Reverse transcription-quantitative polymerase chain reaction and western blotting were performed to determine the mRNA and protein expression levels of cdc25a, one of the identified candidate genes, in human, rat and tree shrew samples. The cell cycle pathway had the largest overlap between the GSEA and meta-analysis. Meta-analyses showed that 25 genes, including cdc25a, in the cell cycle pathway were differentially expressed. Cdc25a mRNA levels in HCC tissues were higher than those in normal liver tissues in humans, rats and tree shrews, and the expression level of cdc25a in HCC tissues was higher than in corresponding paraneoplastic tissues in humans and rats. In human HCC tissues, the cdc25a mRNA level was significantly correlated with clinical stage, portal vein tumor thrombosis and extrahepatic metastasis. Western blotting showed that, cdc25a protein levels were significantly upregulated in HCC tissues in humans, rats and tree shrews. In conclusion, GSEA and meta-analysis can be combined to identify key molecules and pathways involved in HCC. This study demonstrated that the cell cycle pathway and the cdc25a gene may be crucial in the pathogenesis and progression of HCC.

Peroxiredoxin II promotes hepatic tumorigenesis through cooperation with Ras/Forkhead box M1 signaling pathway. Oncogene 2015; 35:3503-13.

Abstract
The current study was carried out to define the involvement of Peroxiredoxin (Prx) II in progression of hepatocellular carcinoma (HCC) and the underlying molecular mechanism(s). Expression and function of Prx II in HCC was determined using H-ras(G12V)-transformed HCC cells (H-ras(G12V)-HCC cells) and the tumor livers from H-ras(G12V)-transgenic (Tg) mice and HCC patients. Prx II was upregulated in H-ras(G12V)-HCC cells and H-ras(G12V)-Tg mouse tumor livers, the expression pattern of which highly similar to that of forkhead Box M1 (FoxM1). Moreover, either knockdown of FoxM1 or site-directed mutagenesis of FoxM1-binding site of Prx II promoter significantly reduced Prx II levels in H-ras(G12V)-HCC cells, indicating FoxM1 as a direct transcription factor of Prx II in HCC. Interestingly, the null mutation of Prx II markedly decreased the number and size of tumors in H-ras(G12V)-Tg livers. Consistent with this, knockdown of Prx II in H-ras(G12V)-HCC cells reduced the expression of cyclin D1, cell proliferation, anchorage-independent growth and tumor formation in athymic nude mice, whereas overexpression of Prx II increased or aggravated the tumor phenotypes. Importantly, the expression of Prx II was correlated with that of FoxM1 in HCC patients. The activation of extracellular signal-related kinase (ERK) pathway and the expression of FoxM1 and cyclin D1 were highly dependent on Prx II in H-ras(G12V)-HCC cells and H-ras(G12V)-Tg livers. Prx II is FoxM1-dependently-expressed antioxidant in HCC and function as an enhancer of Ras(G12V) oncogenic potential in hepatic tumorigenesis through activation of ERK/FoxM1/cyclin D1 cascade.

Abstract
In this study, we used proteomic profiling to compare hepatocellular carcinoma (HCC) and peri-tumoral tissues to identify potential tumor markers of HCC. We identified eight differentially expressed proteins (>3-fold), including Peroxiredoxin 6 (PRDX6). PRDX6 is a bifunctional enzyme with both peroxidase and calcium-independent phospholipase A2 (iPLA2) activity. We found that peri-tumoral tissues expressed higher levels of PRDX6 mRNA (n = 59, P = 0.018) and protein (n = 265, P < 0.001) than HCC tissues, and that decreased expression of PRDX6 in HCC tissues was an independent risk factor indicating a poor prognosis (n = 145, P = 0.007). Combining the examination of serum PRDX6 with α-fetoprotein improved the diagnostic sensitivity of tests for HCC compared to α-fetoprotein alone (85.0% vs 50.0%, n = 40). We found that PRDX6 induced S phase arrest in HCC cells and inhibited HCC tumorigenicity in mice injected with cancer cells. When treated with H2 O2 , PRDX6 inhibited apoptosis. When treated with tumor necrosis factor alpha (TNF-α), PRDX6 promoted apoptosis. Inhibition of iPLA2 activity of PRDX6 decreased the apoptosis induced by TNF-α. In conclusion, PRDX6 inhibited the carcinogenesis of HCC, and the iPLA2 activity of PRDX6 promoted cancer cell death induced by TNF-α. © 2015 Wiley Periodicals, Inc.

Peroxiredoxins (Prxs) are a family of thiol peroxidases, which have been suggested to serve as biomarkers for diseases caused by oxidative stress. In this study, we established a high performance liquid chromatography (HPLC) method for quantifying the amount of Prx2 in red blood cells (RBCs). RBC proteins were separated using HPLC, and a single peak was detected that matched that produced by recombinant Prx2. Under improved conditions, the calibration curve for Prx2 (reduced form) was linear over the range of 0.5-20.0μg with a correlation coefficient of 0.999. The minimum detectable level of the recombinant Prx2 was 0.2μg, with a signal-to-noise ratio of 3 per 20μl of injection volume. SDS-PAGE and mass spectrometric analysis showed that the proteins comprising the peak were almost exclusively Prx2. Further high-resolution analysis using nanoLC-MS/MS demonstrated that the oxidation sensitive, Cys-51 was carbamidomethylated by iodoacetamide-alkylation during in-gel digestion but was not modified with sulfinic acid (-SO2H) or sulfonic acid (-SO3H). These results indicated that the separated Prx2 was the reduced form and not the hyperoxidized form. These basic experiments allowed us to determine the relative amounts of native Prx2 in RBCs taken from healthy subjects. The average levels of Prx2 in male and female subjects were 7.28ng/mg and 8.29ng/mg, respectively, and no significant difference was observed between the sexes. Therefore, the HPLC method with UV detection described herein offers a convenient method to quantitatively determine the levels of reduced form of Prx2 and its oxidative decrease in human RBCs.

Abstract
BACKGROUND Hepatitis B virus (HBV) infection has been believed as a major cause of hepatocellular carcinoma (HCC) for a long time, however, the evidences of which are mostly from clinical and epidemiological investigations while there is no evidence from animal experiments. Tree shrew (Tupaia) is a small animal closely related to primates evolutionarily, with about 8 years of lifespan. Our previous study proved that tree shrews can be chronically HBV-infected after being inoculated neonatally with HBV. The present study reports the further results from the longer-term observation of these animals. METHODS Neonatal tree shrews were inoculated with sera from HBV-infected patient or tree shrew. Their serum samples and liver biopsies were collected periodically for detection of HBV markers as well as for histopathological and immunohistochemical examinations. Group A consisted of six tree shrews with chronic HBV-infection, and group B consisted of nine tree shrews without chronic HBV infection. RESULTS Periodical examinations on serum and liver biopsies of the animals in group A showed the progress of HBV infection, and two cases of HCC occurred at their late stage of life. The courses of HBV infection and the hepatic histopathological and immunohistochemical changes in the tree shrews were similar to those in humans. In contrast, neither HCC nor obvious hepatitis histopathological change was found among the tree shrews in group B. CONCLUSIONS The course of HBV infection and the features of HCC discovered in tree shrews are similar to those of chronically HBV-infected humans. The tree shrew model might be used to investigate the underlying mechanisms favoring susceptibility for chronic HBV infection and disease progression.

Abstract
Liver cancer is the fifth most common cancer, but the second leading cause of cancer death, in the world, with more than 700,000 fatalities annually. The major etiology of liver cancer is infection with an hepatotropic virus such as hepatitis B virus or hepatitis C virus infection. While chronic viral infection remains the main cause of liver disease and risk of hepatocellular carcinoma (HCC), rates of nonviral-associated HCC are occurring at an alarmingly increasing rate. Like many cancers, survival rates are closely associated with time of detection. If HCC is caught early, survival rates can be as high as 50%. Regrettably, most cases of HCC are caught late where survival rates can be as low as 2-7%. Thus, there has been great interest in discovering serum biomarkers that could be used to identify those with HCC. To this end, many groups have examined the N-linked glycans to identify changes that occur with HCC. As the liver secretes the vast majority of proteins into the serum, this has often been a starting point for study. In serum, alterations in core fucosylation, outer-arm fucosylation, increased sialylation, and glycan branching have been observed in patients with HCC. Similar findings have been found directly in HCC tissue suggesting that these glycan changes may play a role in tumor formation and development.

Abstract
AIM: To investigate the effect of recombinant lentiviral mediated RNA interference (RNAi) targeting the fatty acid binding protein-5 (FABP-5) gene on cell proliferation, apoptosis and invasiveness in human hepatocellular carcinoma cell line HepG2, and to explore the possible underlying mechanisms.
METHODS: Three vectors carrying short hairpin RNAs (shRNAs) targeting the FABP-5 gene (FABP-5-shRNA expression vectors) were constructed and selected for the most effective one. HepG2 cells were divided into three groups: an experimental group, a normal control group and a negative control group. For the experimental group, HepG2 cells were transfected with the recombinant lentiviral vector (LV-shRNA-FABP-5), the negative control group was transfected with a control lentiviral vector (LV-shRNA-NC), and the normal control group did not undergo any treatment. The mRNA level of FABP-5 was analyzed by reverse transcription-polymerase chain reaction (RT-PCR) and quantitative real-time polymerase chain reaction (qPCR). The relative expression of FABP-5 protein was analyzed by Western blot. Cell proliferation was detected by MTT assay, cell colony formation was detected by Giemsa staining, cell invasion ability was assessed using the cell invasion chamber method, and cell cycle and apoptosis were observed by flow cytometry (FCM).
RESULTS: FABP-5-shRNA expression vectors were transfected into HepG2 cells, and fluorescence analysis indicated that > 90% of cells showed fluorescence signal. Compared with the normal control group and negative control group, FABP-5 mRNA and protein expression was significantly down-regulated in cells transfected with the three shRNA carrying vectors, with the LV-shRNA-FABP-5 having the highest efficiency ( P < 0.05). HepG2 cell transfected with the FABP-5-shRNA had significantly reduced proliferation and invasion compared with the other two groups ( P < 0.05). Flow cytometry analysis showed that the experimental group showed obvious apoptosis ( P < 0.05). The percentage of cells in G2/M phase significantly increased in cells transfected with the FABP-5-shRNA ( P < 0.05).
CONCLUSION: The high expression of the FABP-5 gene could be silenced by RNAi, and RNAi-induced FABP-5 knockdown could effectively inhibit the proliferation and invasion of HepG2 cells, block the cell cycle in G2/M phase, and significantly increase cell apoptosis.

Abstract
Tree shrew has increasingly become an attractive experimental animal model for human diseases, particularly for breast cancer due to spontaneous breast tumours and their close relationship to primates and by extension to humans. However, neither normal mammary glands nor breast tumours have been well characterised in the Chinese tree shrew (Tupaia belangeri chinensis). In this study, normal mammary glands from four different developmental stages and 18 spontaneous breast tumours were analysed. Haematoxylin and eosin (H&E) staining and immunohistochemistry (IHC) showed that normal mammary gland morphology and structures of tree shrews were quite similar to those found in humans. Spontaneous breast tumours of tree shrews were identified as being intraductal papilloma, papillary carcinoma, and invasive ductal carcinoma with or without lung metastasis. To further analyse breast cancer tumours among tree shrews, 40 3-4 month-old female tree shrews were orally administrated 20 mg 7,12-dimethylbenz(a)anthracene (DMBA) or peanut oil thrice, and then, 15 of these DMBA administrated tree shrews were implanted with medroxyprogesterone acetate (MPA) pellets. DMBA was shown to induce breast tumours (12%) while the addition of MPA increased the tumour incidence (50%). Of these, three induced breast tumours were intraductal papillary carcinomas and one was invasive ductal carcinoma (IDC). The PTEN/PIK3CA (phosphatase and tensin homologue/phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha), but not TP53 and GATA3, genes are frequently mutated in breast tumours, and the PTEN/PIK3CA gene mutation status correlated with the expression of pAKT in tree shrew breast tumours. These results suggest that tree shrews may be a promising animal model for a subset of human breast cancers with PTEN/PIK3CA gene mutations.

Abstract
We cocultured calycosin with human hepatocellular carcinoma cell line (BEL-7402) to investigate the effect on cell proliferation. Calycosin can markedly block the cell growth in G1 phase (P < 0.01) on the IC50 concentration. There were seventeen genes involved in cell-cycle regulation showing differentially expressed in treated cells detected by gene chip. Eight genes were upregulated and nine genes were downregulated. Downregulated TFDP-1, CDKN2D, and SPK2 and upregulated CDC2 and CCNB1 might affect cell cycle of tumor cells. Furthermore, we checked the transcription pattern using 2D gel method to find different expression of proteins in human hepatocellular carcinoma cells after exposure to calycosin. Fourteen proteins were identified by matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS). Twelve proteins expression were increased such as transgelin 2, pyridoxine 5′-phosphate, stress-induced-phosphoprotein 1, peroxiredoxin 1, endoplasmic reticulum protein 29, and phosphoglycerate mutase 1. Only thioredoxin peroxidase and high-mobility group box1 proteins' expression decreased. Both genes and proteins changes might be relate to the mechanism of antitumor effect under treatment of calycosin. In conclusion, calycosin has a potential effect to inhibit the BEL-7402 cell growth by inhibiting some oncogene expression and increasing anticancer genes expression, what is more, by blocking cell cycle.

Abstract
Aflatoxin B1 (AFB1) is a potent hepatocarcinogen that causes carcinogenesis in many animal species. In previous study, we found that isocitrate dehydrogenase 3α subunit (IDH3α) was upregulated in AFB1-induced carcinogenesis process. In this study, the sequences of IDH3α from various species were compared and the protein expression levels in different organs were examined, and the results showed that IDH3α was a widely distributed protein and shared highly conserved sequence in various species. In the same time, IDH3α was demonstrated to accumulate in a dose-dependent manner induced by AFB1 in cells, and was also up-regulated in the process of AFB1-induced liver lesion. Similar results were observed when H2O2 was used to replace AFB1. Over-expression of IDH3α increased the phosphorylation level of Akt (Protein kinase B) and neutralized the cellular toxicity induced by AFB1 or H2O2 and apoptosis induced by AFB1, while the reduced expression of IDH3α by siRNA decreased the phosphorylation, indicating that IDH3α played important roles in oxidative stress-induced PI3K/Akt pathway. Overall, the results suggested that AFB1 treatment could increase the expression of IDH3α, and the activated PI3K/Akt pathway by IDH3α eventually neutralized the apoptosis induced by AFB1.

Abstract
AIM: To investigate the differential expression of epidermal fatty acid binding protein (E-FABP) in hepatocellular carcinoma (HCC) tissues from different species and to analyze the relationship between the expression of E-FABP and clinicopathological parameters of HCC.
METHODS: Immunohistochemical staining was performed to detect the expression of E-FABP in tissue samples of HCC, tumor-adjacent liver samples and normal liver samples collected from human, tree shrew and rats. Reverse transcription PCR (RT-PCR) was used to detect the expression of E-FABP mRNA in 60 human HCC and matched tumor-adjacent specimens. Statistical analysis was performed to analyze the relationship between E-FABP expression and clinicopathological parameters of HCC,including serum alpha-fetoprotein (AFP).
RESULTS: The expression of E-FABP protein increased significantly in HCC tissues of all the three species (all P < 0.05). E-FABP mRNA expression increased significantly in human HCC tissues (P < 0.05). Analysis of the relationship between expression of E-FABP and clinicopathological parameters of HCC showed that E-FABP expression was related to HCC metastasis. Combined detection of liver E-FABP and serum AFP might be helpful to detect early HCC.
CONCLUSION: E-FABP may be used as a biomarker for predicting HCC metastasis and diagnosing early HCC. Since E-FABP is differentially expressed in HCC tissues of different species, it may play a key role in hepatocarcinogenesis and therefore might be used as a target for preventing or treating HCC.

Abstract
The major histocompatibility complex (MHC) class I genes play a pivotal role in the adaptive immune response among vertebrates. Accordingly, in numerous mammals the genomic structure and molecular characterization of MHC class I genes have been thoroughly investigated. To date, however, little is known about these genes in tree shrews, despite the increasingly popularity of its usage as an animal model. To address this deficiency, we analyzed the structure and characteristic of the tree shrew MHC class I genes (Tube-MHC I) and performed a comparative gene analysis of the tree shrew and other mammal species. We found that the full-length cDNA sequence of the tree shrew MHC class I is 1074bp in length. The deduced peptide is composed of 357 amino acids containing a leader peptide, an α1 and α2 domain, an α3 domain, a transmembrane domain and a cytoplasmic domain. Among these peptides, the cysteines, CD8(+) interaction and N-glycosylation sites are all well conserved. Furthermore, the genomic sequence of the tree shrew MHC class I gene was identified to be 3180bp in length, containing 8 exons and 7 introns. In 21 MHC class I sequences, we conducted an extensive study of nucleotide substitutions. The results indicated that in the peptide binding region (PBR) the rate of non-synonymous substitutions (dN) to synonymous substitutions (dS) was greater than 1, suggesting balancing selection at the PBR. These findings provide valuable contributions in furthering our understanding of the structure, molecular polymorphism, and function of the MHC class I genes in tree shrews, further improving their utility as an animal model in biomedical research.

Abstract
AIMS Several groups found different impact of erythropoietin (EPO) on liver regeneration. Both pro-proliferative as well as anti-proliferative and non-proliferative activities have been reported using high dosage of EPO. Systemic administration of high doses of this cytokine is a clinical concern due to risk of thrombosis. Herein, we applied EPO in low dosages and investigated whether it can stimulate liver regeneration after liver resection. MAIN METHODS Parameters of liver regeneration were assessed 3 days after 70% hepatectomy by means of immunochemistry and proteomics. EPO was given twice in low dosages (200 and 600 IU/kg BW). KEY FINDINGS We showed that EPO facilitated hepatic regeneration in rats. Enhanced hepatocyte proliferation (Ki67, BrdU-positive cells) was observed in all EPO-treated groups. By performing Differential Proteomic analysis, we identified two proteins which resulted sensitive to EPO treatment after hepatectomy: Peroxiredoxin-1 and glutathione S-transferase Mu 1. SIGNIFICANCE Based on our results, low doses of rhEPO increase the hepatic regenerative capacity after partial hepatectomy in rats by enhancing hepatocyte proliferation and acting on antioxidant enzymes. Both proteins identified by proteomic analysis have not previously been associated with liver regeneration and will aid in the understanding of EPO's regenerative response having clinical implications to treat liver failure.

Abstract
MicroRNA-122a (miR-122a) is a liver-specific miRNA that is frequently downregulated in hepatocellular carcinoma (HCC). The exact functional role of miR-122a and its target in HCC remain largely unknown. We developed a lentiviral vector for the expression of pre-miR-122a (Lenti-miR-122a). Lenti-miR-122a inhibited HCC cell growth and induced apoptosis in vitro. We employed proteomic profiling to identify the target proteins of miR-122a. In total, ten proteins with differential expression in HCC cells infected with Lenti-miR-122a were identified. Amongst them, downregulation of peroxiredoxin 2 (PRDXII) by miR-122a was validated by Western blotting. Using bioinformatics analysis, predictable target sites of miR-122a were identified in the 5'-UTR of PRDXII mRNA. Luciferase reporter assay confirmed the regulation of miR-122a on 5'-UTR of PRDXII. In conclusion, PRDXII was identified to be the new target of miR-122a.

Abstract
The advances in genomics and proteomics have led to identification of numerous differentially expressed cancer-related genes. The current challenge in the field of cancer research is to screen the crucial molecules in carcinogenesis from the vast amounts of data. These crucial molecules can be applied as the targets for cancer prevention and therapy. In addition, identification of these crucial molecules is helpful in understanding the mechanism of carcinogenesis. Cross-species strategy refers to identification of crucial molecules in carcinogenesis by exploring the similarity between cancer-related gene expression profiles of human beings and other species. This paper reviews the recent advances in the application of this new cancer research strategy.

Hsp90 inhibitor 17-allylamino-17-demethoxygeldanamycin inhibits the proliferation of ARPE-19 cells. J Biomed Sci 2010; 17:30. [PMID: 20416086 PMCID: PMC2873497 DOI: 10.1186/1423-0127-17-30] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2009] [Accepted: 04/23/2010] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The antiproliferative effect of the Hsp90 inhibitor 17-AAG (17-allylamino-17-demethoxygeldanamycin) on human retinal pigment epithelial cells is investigated. METHODS MTT and flow cytometry were used to study the antiproliferative effects of the 17-AAG treatment of ARPE-19 cells. 2D gel electrophoresis (2-DE) and mass spectrometry were applied to detect the altered expression of proteins, which was verified by real-time PCR. Gene Ontology analysis and Ingenuity Pathway Analysis (IPA) were utilized to analyze the signaling pathways, cellular location, function, and network connections of the identified proteins. And SOD assay was employed to confirm the analysis. RESULTS 17-AAG suppressed the proliferation of ARPE-19 cells by inducing cell cycle arrest and apoptosis. Proteomic analysis revealed that the expression of 94 proteins was altered by a factor of more than 1.5 following exposure to 17-AAG. Of these 94, 87 proteins were identified. Real-time PCR results indicated that Hsp90 and Hsp70, which were not identified by proteomic analysis, were both upregulated upon 17-AAG treatment. IPA revealed that most of the proteins have functions that are related to oxidative stress, as verified by SOD assay, while canonical pathway analysis revealed glycolysis/gluconeogenesis. CONCLUSIONS 17-AAG suppressed the proliferation of ARPE-19 cells by inducing cell cycle arrest and apoptosis, and possibly by oxidative stress.

Meng JY, Zhang CY, Lei CL. A proteomic analysis of Helicoverpa armigera adults after exposure to UV light irradiation. JOURNAL OF INSECT PHYSIOLOGY 2010; 56:405-411. [PMID: 19944107 DOI: 10.1016/j.jinsphys.2009.11.015] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2009] [Revised: 11/17/2009] [Accepted: 11/19/2009] [Indexed: 05/28/2023]
Abstract
Ultraviolet (UV) light (blacklight), which emits UV in the range of 320-400nm, has been used worldwide in light trapping of insect pests. To gain a better understanding of the response of Helicoverpa armigera adults to UV light irradiation, we carried out a comparative proteomic analysis. Three-day-old adults were exposed to UV light for 1h. Total proteins were extracted and separated by two-dimensional gel electrophoresis. More than 1200 protein spots were reproducibly detected, including 12 that were more abundant and 21 less abundant. Mass spectrometry analysis and database searching helped us to identify 29 differentially abundant proteins. The identified proteins were categorized into several functional groups including signal transduction, RNA processing, protein processing, stress response, metabolisms, and cytoskeleton structure, etc. This study is the first analysis of differentially expressed proteins in phototactic insects under UV light irradiation conditions and gives new insights into the adaptation mechanisms responsive to UV light irradiation stress.

[PMID: 19500902 DOI: 10.1016/j.canlet.2009.04.043] [Citation(s) in RCA: 95] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2009] [Revised: 04/29/2009] [Accepted: 04/30/2009] [Indexed: 01/01/2023]
Abstract
Reactive oxygen species (ROS) are toxic at high levels in the mammalian cells. Mammalian cells have developed many enzymatic and nonenzymatic antioxidative systems in various cellular compartments to maintain an appropriate level of ROS and regulate their action. Peroxiredoxins (Prxs), a family of peroxidase that reduced intracellular peroxides (one type of ROS) with the thioredoxin system as the electron donor, were highly expressed in various cellular compartments. In this minireview, we discussed the regulation of Prxs expression in cancer cell and its relationship with ionizing radiation. As Prxs could be induced by radiation and its expression status could determine the radiosensitivity of cancer cells, Prxs might be a potential target for radiotherapy in cancer.
