Abstract
The serine/threonine phosphatase family is important in tumor progression and survival. Due to the high conserved catalytic domain, designing selective inhibitors is challenging. Herein, we obtained compound 28a with 38-fold enhanced PP5 selectivity (PP2A/5 IC50 = 33.8/0.9 μM) and improved drug-like properties (favorable stability and safety, F = 82.0%) by rational drug design based on a phase II PP2A/5 dual target inhibitor LB-100. Importantly, we found the spatial conformational restriction of the 28a indole fragment was responsible for the selectivity of PP5. Thus, 28a activated p53 and downregulated cyclin D1 and MGMT, which showed potency in cell cycle arrest and reverse temozolomide (TMZ) resistance in the U87 MG cell line. Furthermore, oral administration of 28a and TMZ was well tolerated to effectively inhibit tumor growth (TGI = 87.7%) in the xenograft model. Collectively, these results implicate 28a could be a drug candidate by reversing TMZ resistance with a selective PP5 inhibition manner.

Trujillo-Hernandez JA, Levine RL. Response to oxidative stress of AML12 hepatocyte cells with knockout of methionine sulfoxide reductases. Free Radic Biol Med 2023; 205:100-106. [PMID: 37290581 DOI: 10.1016/j.freeradbiomed.2023.05.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 05/23/2023] [Accepted: 05/29/2023] [Indexed: 06/10/2023]
Abstract
Methionine sulfoxide reductases are enzymes that reduce methionine oxidation in the cell. In mammals there are three B-type reductases that act on the R-diastereomer of methionine sulfoxide, and one A-type reductase (MSRA) that acts on the S-diastereomer. Unexpectedly, knocking out the four genes in the mouse protected from oxidative stresses such as ischemia-reperfusion injury and paraquat. To elucidate the mechanism by which lack of the reductases protects against oxidative stresses, we aimed to create a cell culture model with AML12 cells, a differentiated hepatocyte cell line. We employed CRISPR/Cas9 to create lines lacking the four individual reductases. All were viable and their susceptibility to oxidative stresses was the same as the parental strain. The triple knockout lacking all three methionine sulfoxide reductases B was also viable, but the quadruple knockout was lethal. We thus modeled the quadruple knockout mouse by creating an AML12 line lacking the three MSRB and heterozygous for the MSRA (Msrb3KO-Msra+/-). We measured the effect of ischemia-reperfusion on the various AML12 cell lines, using a protocol that modeled the ischemic phase by glucose and oxygen deprivation for 36 h followed by return of glucose and oxygen for 3 h as the reperfusion phase. This stress killed ∼50% of the parental line, an effect we chose to facilitate detection of either protective or deleterious changes in the knockout lines. Unlike the protection afforded the mouse, the knockout lines produced by CRISPR/Cas9 did not differ from the parental line in their response to ischemia-reperfusion injury or paraquat poisoning. In the mouse, inter-organ communication may be essential for protection induced by lack of methionine sulfoxide reductases.

Deciphering the Effect of Different Genetic Variants on Hippocampal Subfield Volumes in the General Population. Int J Mol Sci 2023; 24:ijms24021120. [PMID: 36674637 PMCID: PMC9861136 DOI: 10.3390/ijms24021120] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/02/2023] [Accepted: 01/03/2023] [Indexed: 01/11/2023] Open
Abstract
The aim of this study was to disentangle the effects of various genetic factors on hippocampal subfield volumes using three different approaches: a biologically driven candidate gene approach, a hypothesis-free GWAS approach, and a polygenic approach, where AD risk alleles are combined with a polygenic risk score (PRS). The impact of these genetic factors was investigated in a large dementia-free general population cohort from the Study of Health in Pomerania (SHIP, n = 1806). Analyses were performed using linear regression models adjusted for biological and environmental risk factors. Hippocampus subfield volume alterations were found for APOE ε4, BDNF Val, and 5-HTTLPR L allele carriers. In addition, we were able to replicate GWAS findings, especially for rs17178139 (MSRB3), rs1861979 (DPP4), rs7873551 (ASTN2), and rs572246240 (MAST4). Interaction analyses between the significant SNPs as well as the PRS for AD revealed no significant results. Our results confirm that hippocampal volume reductions are influenced by genetic variation, and that different variants reveal different association patterns that can be linked to biological processes in neurodegeneration. Thus, this study underlines the importance of specific genetic analyses in the quest for acquiring deeper insights into the biology of hippocampal volume loss, memory impairment, depression, and neurodegenerative diseases.

Abstract
Background: The combination of deep learning methods and oncogenomics can provide an effective diagnostic method for malignant tumors; thus, we attempted to construct a reliable artificial neural network model as a novel diagnostic tool for Bladder cancer (BLCA). Methods: Three expression profiling datasets (GSE61615, GSE65635, and GSE100926) were downloaded from the Gene Expression Omnibus (GEO) database. GSE61615 and GSE65635 were taken as the train group, while GSE100926 was set as the test group. Differentially expressed genes (DEGs) were filtered out based on the logFC and FDR values. We also performed Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses to explore the biological functions of the DEGs. Consequently, we utilized a random forest algorithm to identify feature genes and further constructed a neural network model. The test group was given the same procedures to validate the reliability of the model. We also explored immune cells' infiltration degree and correlation coefficients through the CiberSort algorithm and corrplot R package. The qRT-PCR assay was implemented to examine the expression level of the feature genes in vitro. Results: A total of 265 DEGs were filtered out and significantly enriched in muscle system processes, collagen-containing and focal adhesion signaling pathways. Based on the random forest algorithm, we selected 14 feature genes to construct the neural network model. The area under the curve (AUC) of the training group was 0.950 (95% CI: 0.850-1.000), and the AUC of the test group was 0.667 (95% CI: 0.333-1.000). Besides, we observed significant differences in the content of immune infiltrating cells and the expression levels of the feature genes. Conclusion: After repeated verification, our neural network model had clinical feasibility to identify bladder cancer patients and provided a potential target to improve the management of BLCA.

Abstract
AIMS Non-small cell lung cancer (NSCLC) is a malignant tumor with high mortality, which seriously endangers human health. The clinical significance, biological function and potential mechanism of Zinc finger protein 655 (ZNF655) in NSCLC are discussed in this study. MATERIALS AND METHODS The expression level of ZNF655 in NSCLC was clarified by immunohistochemical (IHC) staining. Subsequently, lentivirus-mediated shRNA was used to construct ZNF655 knock down NSCLC cells NCI-H1299 and A549. In vitro and in vivo loss of function assays were used to evaluate the malignant behaviors of the cells. KEY FINDINGS The expression level of ZNF655 was abnormally abundant in NSCLC. The decrease of ZNF655 expression led to the inhibition of the malignant behaviors of NSCLC, which was manifested by weakened proliferation, increased sensitivity to apoptosis, cycle repression at G2 and weakened migration. Consistently, downregulation of ZNF655 reduced tumorigenesis in mouse xenograft model. Moreover, decreased expression of ZNF655 resulted in upregulated expression of Bad, Bax, Fas, p21, p27, Caspase 3 and Caspase 8 in NSCLC cells. NCI-H1299 cells with ZNF655 knockdown resulted in decreased phosphorylation of Akt, downregulation of CDK6 and PIK3CA, and upregulation of MAPK9. Collectively, ZNF655 may regulate apoptosis of NSCLC cells through PI3K/Akt and p53 signaling pathways. SIGNIFICANCE ZNF655 possessed a promoting effect in the progression of NSCLC, which may serve as a promising molecular target for clinical treatment.

Abstract
Methionine oxidation and reduction is a common phenomenon occurring in biological systems under both physiological and oxidative-stress conditions. The levels of methionine sulfoxide (MetO) are dependent on the redox status in the cell or organ, and they are usually elevated under oxidative-stress conditions, aging, inflammation, and oxidative-stress related diseases. MetO modification of proteins may alter their function or cause the accumulation of toxic proteins in the cell/organ. Accordingly, the regulation of the level of MetO is mediated through the ubiquitous and evolutionary conserved methionine sulfoxide reductase (Msr) system and its associated redox molecules. Recent published research has provided new evidence for the involvement of free MetO or protein-bound MetO of specific proteins in several signal transduction pathways that are important for cellular function. In the current review, we will focus on the role of MetO in specific signal transduction pathways of various organisms, with relation to their physiological contexts, and discuss the contribution of the Msr system to the regulation of the observed MetO effect.

Abstract
Oxidative and endoplasmic reticulum (ER) stress are involved in mediating high-fat diet (HFD)-induced insulin resistance. As the ER-localized methionine sulfoxide reductase B3 (MsrB3) protects cells against oxidative and ER stress, we hypothesized that MsrB3 might be associated with HFD-induced insulin resistance. To test this hypothesis, we examined the effect of MsrB3 deficiency on HFD-induced insulin resistance using MsrB3 knockout (KO) mice. Mice were fed a control diet or HFD for 12 weeks and insulin sensitivity was measured using a hyperinsulinemic-euglycemic clamp. HFD consumption increased the body weight of both wild-type and MsrB3 KO mice, and no significant difference was observed between the genotypes. The HFD increased oxidative stress and induced insulin resistance in the skeletal muscle of wild-type mice, but did not affect either in MsrB3 KO mice. The unfolded protein response (UPR) was increased in MsrB3 KO mice upon consumption of HFD, but not in wild-type mice. Mitochondrial oxidative phosphorylation proteins and the levels of superoxide dismutase 2 and glutathione peroxidase 1 were increased in MsrB3 KO mice upon HFD consumption. The respiratory control ratio was reduced in wild-type mice consuming HFD but not in MsrB3 KO mice. The levels of calcium/calmodulin-dependent protein kinase kinase β, phosphorylated AMP-activated protein kinase, and peroxisome proliferator-activated receptor gamma coactivator 1α were increased in MsrB3 KO mice following HFD consumption. These results suggest that MsrB3 deficiency inhibits HFD-induced insulin resistance, and the increased mitochondrial biogenesis and antioxidant induction might be the mechanisms underlying this phenomenon.

Abstract
Clinical application of doxorubicin (Dox) is limited due to its serious side effects including nephrotoxicity, and kidney podocytes play important roles in renal diseases. MicroRNAs (miRNAs) are critical regulators associated with human diseases. The purpose of this study was to explore a novel target in adjusting Dox-induced renal podocyte injury. Through a double luciferase reporter gene experiment, it was found that miR-874-3p directly targeted methionine sulfoxide reductase B3 (MsrB3). During the tests of miR-874-3p inhibitor and MsrB3 siRNA in human podocytes or miR-874-3p antagomir in mice, we found that the expression levels of downstream oxidative stress and apoptosis-related proteins were regulated by miR-874-3p/MsrB3 signal to alleviate or aggravate renal podocyte injury. The data in the present work showed that miR-874-3p aggravated Dox-caused renal podocyte injury by promoting apoptosis and oxidative damage via inhibiting MsrB3. Therefore, miR-874-3p/MsrB3 should be considered as a new therapeutic target in controlling renal podocyte injury induced by Dox.

Abstract
Background 12q14 microdeletion syndrome is characterized by low birth weight and failure to thrive, proportionate short stature and developmental delay. The opposite syndrome (microduplication) has not yet been characterized. Our main objective is the recognition of a new clinical entity - 12q14 microduplication syndrome. - as well as confirming the role of HMGA2 gene in growth regulation. Case presentation Array Comparative Genomic Hybridization (CGH), Karyotype, Fluorescence in situ Hybridization, Quantitative-PCR analysis and Whole exome sequencing (WES) were performed in a girl presenting overgrowth and obesity. Array CGH identified a 1.5 Mb 12q14.3 microduplication involving HMGA2, GRIP1, IRAK3, MSRB3 and TMBIM4 genes. Karyotype and FISH showed that duplication was a de novo insertion of 12q14.3 region on chromosome 9p resulting in an interstitial microduplication. Q-PCR confirmed the duplication only in the proband. WES revealed no pathogenic variants. Conclusions Phenotypic comparison with patients with 12q14 microdeletion syndrome showed a reciprocal presentation, suggesting a phenotypically recognizable 12q14 microduplication syndrome as well as confirming the role of HMGA2 gene in growth regulation. It is also indicative that other genes, such as IRAK3 and MSRB3 might have of role in weight gain and obesity.

Abstract
Methionine sulfoxide reductase B3 (MSRB3) is instrumental in ossification and fat deposition, which regulate the
growth and development of cattle directly. The purpose of this study was
aimed to explore insertions and deletions (indels) in MSRB3 gene and investigate
their association with growth traits in four indigenous cattle breeds (Luxi
cattle, Qinchuan cattle, Nanyang cattle, and Jiaxian Red cattle). Four indels
were identified by sequencing with DNA pool. Association analysis showed
that three of them were associated with growth traits (P<0.05). For
P1, the DD (deletion and deletion) genotype was significantly associated with body length of Nanyang
cattle; for P6, II (insertion and insertion) and/or DD genotypes were significantly associated with
enhanced growth traits of Qinchuan cattle; for P7, II genotype was
significantly associated with hucklebone width of Luxi cattle. Our results
demonstrated that the polymorphisms in bovine MSRB3 gene were significantly
associated with growth traits, which could be candidate loci for
marker-assisted selection (MAS) in cattle breeding.

[PMID: 31889586 DOI: 10.1016/j.prp.2019.152780] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 11/29/2019] [Accepted: 12/01/2019] [Indexed: 11/24/2022]
Abstract
BACKGROUND Renal cancer represents about 3 % of all human cancers. Clear cell renal cell carcinoma (ccRCC) is the main type of renal cancer. Methionine sulfoxide reductase B3 (MSRB3) is a protein repair enzyme that specifically catalyzes the reduction of methionine-R-sulfoxide residues and has an antioxidant function. However, MSRB3's role in ccRCC is still obscure. METHODS Immunohistochemical staining and Real-time PCR were used to compare the expression level of MSRB3 in ccRCC tissues and adjacent tissues. Western blot was used to detect the expression of MSRB3 in cell lines. Chi-square test were applied to evaluate the potential of MSRB3 to function as a cancer biomarker. RNA interference was used to inhibit MSRB3 expression in ccRCC cells, followed by detecting cell proliferation, apoptosis, migration and invasion. The markers of endoplasmic reticulum stress were then detected by western blot. RESULTS In this study, we validated that MSRB3 was significantly up-regulated in ccRCC samples and cell lines. It was also demonstrated that the up-regulation of MSRB3 was associated with several clinicopathologic features. Knockdown of MSRB3 remarkably arrested the proliferation, migration and invasion, while promoted apoptosis, and induced the changes of markers of endoplasmic reticulum stress. CONCLUSION In conclusion, we demonstrated that MSRB3 was an oncogene of ccRCC associated with patients' pathological characteristics and modulated endoplasmic reticulum stress of cancer cells.

Abstract
Cervical cancer is the most common gynecological malignancy, the third most common malignant tumor in women worldwide, and the most common malignant tumor among Chinese women. However, despite continuous improvement in medical treatment, the number of cervical cancer cases in China is on the increase annually, consistent with the general trend in global cervical cancer incidence. Therefore, it is particularly important to study the pathogenesis of cervical cancer at the genetic level in China. The aim of the present study was to use the TCGA database to identify potential genetic signatures that could predict the prognosis of patients with cervical cancer and provide evidence supporting clinical genetic intervention in cervical cancer. Primarily, an effective three-gene signature was found that predicts prognosis in patients with cervical cancer. This model can provide prima facie evidence for future assessment of patient risk and prognosis, but further testing is required to improve its accuracy. Our results also suggested that centromere protein M, methionine sulfoxide reductase B3 and Zic family member 2 could be promising biomarkers for the prognosis of cervical cancer.

Abstract
The present study aimed to investigate the expression of methionine sulfoxide reductases B3 (MSRB3) in gastric cancer (GC) and its clinical significance. A total of 90 specimens from patients with GC were collected to evaluate MSRB3 protein expression by immunohistochemical staining. The associations between MSRB3 protein expression, clinicopathological characteristics and prognosis of patients with GC were subsequently investigated. The results demonstrated that MSRB3 protein expression in GC tissues samples was significantly higher compared with that in paired adjacent normal tissues (P=0.017). Among the 90 GC cases, 64 (71.1%) exhibited higher MSRB3 expression. In addition, the diagnostic value of MSRB3 for patients with GC was estimated with a sensitivity of 71.1% and a specificity of 46.7%. However, MSRB3 expression was not associated with clinicopathological characteristics of patients with GC. Kaplan-Meier analysis indicated that patients with high MSRB3 expression had significantly shorter overall survival (OS) times compared with those with low expression (P=0.040). Univariate Cox regression analysis indicated that maximum tumor diameter, depth of invasion, lymph node metastasis, Tumor-Node-Metastasis (TNM) stage and MSRB3 expression were significantly associated with OS time. Multivariate Cox regression analysis indicated that MSRB3 was an independent predicting factor for the OS time of patients with GC (P=0.049). In addition, analysis using The Cancer Genome Atlas (TCGA) database validated these results. Kaplan-Meier analysis revealed that higher MSRB3 mRNA expression was associated with poorer OS time in 442 patients with GC (P=0.004). Univariate analysis of the TCGA data indicated that age, depth of invasion, lymph node metastasis, distant metastasis, TNM stage and MSRB3 expression were significantly associated with OS time; however, sex and histological differentiation were not associated with OS time. Multivariate analysis demonstrated that MSRB3 was an independent prognostic factor in patients with GC (P=0.001). In conclusion, these results demonstrated that MSRB3 expression was upregulated in patients GC, which suggests that MSBR3 may serve as a potential prognostic biomarker.

Abstract
Muscle-invasive bladder urothelial carcinoma (MIBC) is characterized as a genetic heterogeneous cancer with a high percentage of recurrence and worse prognosis. Identify the prognostic potentials of novel genes for muscle-invasive urothelial bladder cancer could at least provide important information for early detection and clinical treatment. Weighted gene co-expression network analysis (WGCNA) algorithm, a powerful systems biology approach, was utilized to extract co-expressed gene networks from mRNA expression dataset to construct transcriptional modules in MIBC samples, which was associated with demographic and clinical traits of MIBC patients. The potential prognostic markers of MIBC were screened out in the discovery dataset and verified in an independent external validation dataset. A total of 8 co-expression modules were detected through the WGCNA algorithm in the discovery datasets based on 401 MIBC samples. One transcriptional module enriched in cell development was observed to be correlated with the MIBC prognosis in the discovery datasets (HR = 1.48, 95%CI = 1.04-2.11) and independently verified in an external dataset (HR = 3.59, 95%CI = 1.09-11.79). High expression of hub genes including discoidin domain receptor tyrosine kinase 2 (DDR2), PDZ and LIM domain 3 (PDLIM3), zinc finger protein 521 (ZNF521), methionine sulfoxide reductase B3 (MSRB3) were significantly associated with the unfavorable survival of MIBC patients. We identified and validated four novel potential biomarkers associated with prognosis of MIBC patients by constructing genes co-expression networks. The discovery of these genetic markers may provide a new target for the development of MIBC chemotherapeutic drugs.

Genet Sel Evol 2018; 50:72. [PMID: 30587124 PMCID: PMC6307293 DOI: 10.1186/s12711-018-0442-6] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2018] [Accepted: 12/18/2018] [Indexed: 01/30/2023] Open
Abstract
Background The size and type of ears are important conformation characteristics that distinguish pig breeds. A significant quantitative trait locus (QTL) for ear size has been identified on SSC5 (SSC for Sus scrofa chromosome) but the underlying causative gene and mutation remain unknown. Thus, our aim was to identify the gene responsible for enlarged ears in pig. Results First, we narrowed down the QTL region on SSC5 to a 137.85-kb interval that harbors only the methionine sulfoxide reductase B3 (MSRB3) gene. Then, we identified a 38.7-kb copy number variation (CNV) that affects the last two exons of MSRB3 and could be the candidate causative mutation for this QTL. This CNV showed complete concordance with genotype at the QTL of the founder animals in a white Duroc × Erhualian F2 intercross and was found only in pigs from six Chinese indigenous breeds with large ears and from the Landrace breed with half-floppy ears. Moreover, it accounted for the significant association with ear size on SSC5 across the five pig populations tested. eQTL mapping revealed that this CNV was significantly associated with the expression of the microRNA (miRNA) miR-584-5p, which interacts with MSRB3, one of its target genes. In vivo and in vitro experiments confirmed that miR-584-5p inhibits the translation of MSRB3 mRNA. Taken together, these results led us to conclude that presence of the 38.7-kb CNV in the genome of some pig breeds affects ear size by altering the expression of miR-584-5p, which consequently hinders the expression of one of its target genes (e.g. MSRB3). Conclusions Our findings shed insight into the underlying mechanism of development of external ears in mammals and contribute to a better understanding of how the presence of CNV can regulate gene expression.

Abstract
Although competing endogenous RNAs (ceRNAs) have been implicated in many solid tumors, their roles in breast cancer subtypes are not well understood. We therefore generated a ceRNA network for each subtype based on the significance of both, positive co-expression and the shared miRNAs, in the corresponding subtype miRNA dys-regulatory network, which was constructed based on negative regulations between differentially expressed miRNAs and targets. All four subtype ceRNA networks exhibited scale-free architecture and showed that the common ceRNAs were at the core of the networks. Furthermore, the common ceRNA hubs had greater connectivity than the subtype-specific hubs. Functional analysis of the common subtype ceRNA hubs highlighted factors involved in proliferation, MAPK signaling pathways and tube morphogenesis. Subtype-specific ceRNA hubs highlighted unique subtype-specific pathways, like the estrogen response and inflammatory pathways in the luminal subtypes or the factors involved in the coagulation process that participates in the basal-like subtype. Ultimately, we identified 29 critical subtype-specific ceRNA hubs that characterized the different breast cancer subtypes. Our study thus provides new insight into the common and specific subtype ceRNA interactions that define the different categories of breast cancer and enhances our understanding of the pathology underlying the different breast cancer subtypes, which can have prognostic and therapeutic implications in the future.

Abstract
LOX regulates cancer progression in a variety of human malignancies. It is overexpressed in aggressive cancers and higher expression of LOX is associated with higher cancer mortality. Here, we report a new function of LOX in mitosis. We show that LOX co-localizes to mitotic spindles from metaphase to telophase, and p-H3(Ser10)-positive cells harbor strong LOX staining. Further, purification of mitotic spindles from synchronized cells show that LOX fails to bind to microtubules in the presence of nocodazole, whereas paclitaxel treated samples showed enrichment in LOX expression, suggesting that LOX binds to stabilized microtubules. LOX knockdown leads to G2/M phase arrest; reduced p-H3(Ser10), cyclin B1, CDK1, and Aurora B. Moreover, LOX knockdown significantly increased sensitivity of cancer cells to chemotherapeutic agents that target microtubules. Our findings suggest that LOX has a role in cancer cell mitosis and may be targeted to enhance the activity of microtubule inhibitors for cancer therapy.

Abstract
We have previously shown that down-regulation of methionine sulfoxide reductase B3 (MsrB3) induces cancer cell apoptosis through the activation of the intrinsic mitochondrial pathway. However, the mechanism through which MsrB3 deficiency results in cancer cell death is poorly understood. In this study, we investigated whether p53 and endoplasmic reticulum (ER) stress are involved in MsrB3 deficiency-induced cancer cell apoptosis using breast and colon cancer cells. MsrB3 depletion resulted in p53 down-regulation at the post-transcriptional level. MsrB3 deficiency induced cell death to a similar extent in both p53 wild-type (p53+/+) and null (p53-/-) cancer cells, suggesting that MsrB3 deficiency-induced apoptosis occurs independently of p53. MsrB3 deficiency significantly increased ER stress, which resulted in apoptosis. In addition, MsrB3 depletion activated the pro-apoptotic Bim molecule, which is essential for ER stress-induced apoptosis. MsrB3 deficiency increased cytosolic calcium levels, suggesting that MsrB3 down-regulation leads to a disturbance of calcium homeostasis in the ER, which consequently triggers ER stress. MsrB3 overexpression in MsrB3-depleted cells reduced ER stress, and was accompanied by at least partial recovery of cell viability. Taken together, our results suggest that MsrB3 plays a critical role in cancer cell apoptosis through the modulation of ER stress status.

Abstract
Methionine sulfoxide reductase B3 (MsrB3) is a protein repair enzyme that specifically catalyzes the reduction of methionine-R-sulfoxide residues and has an antioxidant function. We have previously shown that depletion of MsrB3 suppresses the proliferation of normal mammalian cells by arresting cell cycle. In this study, we report the crucial role of MsrB3 in cancer cell death. Deficiency of MsrB3 induced cancer cell death, while MsrB3 overexpression stimulated cancer cell proliferation. MsrB3 depletion resulted in apoptotic cancer cell death through the activation of the intrinsic mitochondrial pathway. MsrB3 deficiency increased the levels of cellular reactive oxygen species (ROS) and led to redox imbalance, and also increased the Bax to Bcl-2 ratio and cytochrome c release, leading to caspase activation. Treatment of MsrB3-depleted cells with N-acetylcysteine, an ROS scavenger, prevented cell death, suggesting that MsrB3 deficiency-induced cell death is associated with increased ROS production. In addition, MsrB3 depletion activated poly(ADP ribose) polymerase-1 (PARP-1) and led to the translocation of apoptosis-inducing factor (AIF) to the nucleus. Taken together, our results suggest that MsrB3 plays an important role in cancer cell survival through the modulation of the intrinsic apoptosis pathway.

Abstract
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a persistent environmental pollutant that activates the aryl hydrocarbon receptor (AhR) resulting in altered gene expression. In vivo, in vitro, and ex vivo studies have demonstrated that B cells are directly impaired by TCDD, and are a sensitive target as evidenced by suppression of antibody responses. The window of sensitivity to TCDD-induced suppression of IgM secretion among mouse, rat and human B cells is similar. Specifically, TCDD must be present within the initial 12h post B cell stimulation, indicating that TCDD disrupts early signaling network(s) necessary for B lymphocyte activation and differentiation. Therefore, we hypothesized that TCDD treatment across three different species (mouse, rat and human) triggers a conserved, B cell-specific mechanism that is involved in TCDD-induced immunosuppression. RNA sequencing (RNA-Seq) was used to identify B cell-specific orthologous genes that are differentially expressed in response to TCDD in primary mouse, rat and human B cells. Time course studies identified TCDD-elicited differential expression of 515 human, 2371 mouse and 712 rat orthologous genes over the 24-h period. 28 orthologs were differentially expressed in response to TCDD in all three species. Overrepresented pathways enriched in all three species included cytokine-cytokine receptor interaction, ECM-receptor interaction, focal adhesion, regulation of actin cytoskeleton and pathways in cancer. Differentially expressed genes functionally associated with cell-cell signaling in humans, immune response in mice, and oxidation reduction in rats. Overall, these results suggest that despite the conservation of the AhR and its signaling mechanism, TCDD elicits species-specific gene expression changes.

Population structure of eleven Spanish ovine breeds and detection of selective sweeps with BayeScan and hapFLK. Sci Rep 2016; 6:27296.

Abstract
The goals of the current work were to analyse the population structure of 11 Spanish ovine breeds and to detect genomic regions that may have been targeted by selection. A total of 141 individuals were genotyped with the Infinium 50 K Ovine SNP BeadChip (Illumina). We combined this dataset with Spanish ovine data previously reported by the International Sheep Genomics Consortium (N = 229). Multidimensional scaling and Admixture analyses revealed that Canaria de Pelo and, to a lesser extent, Roja Mallorquina, Latxa and Churra are clearly differentiated populations, while the remaining seven breeds (Ojalada, Castellana, Gallega, Xisqueta, Ripollesa, Rasa Aragonesa and Segureña) share a similar genetic background. Performance of a genome scan with BayeScan and hapFLK allowed us identifying three genomic regions that are consistently detected with both methods i.e. Oar3 (150–154 Mb), Oar6 (4–49 Mb) and Oar13 (68–74 Mb). Neighbor-joining trees based on polymorphisms mapping to these three selective sweeps did not show a clustering of breeds according to their predominant productive specialization (except the local tree based on Oar13 SNPs). Such cryptic signatures of selection have been also found in the bovine genome, posing a considerable challenge to understand the biological consequences of artificial selection.

Biochem Biophys Res Commun 2016; 473:1033-1038. [PMID: 27059143 DOI: 10.1016/j.bbrc.2016.04.011] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2016] [Accepted: 04/04/2016] [Indexed: 12/30/2022]
Abstract
Methionine sulfoxide reductase B3 (MsrB3), which is primarily found in the endoplasmic reticulum (ER), is an important protein repair enzyme that stereospecifically reduces methionine-R-sulfoxide residues. We previously found that MsrB3 deficiency arrests the cell cycle at the G1/S stage through up-regulation of p21 and p27. In this study, we report a critical role of MsrB3 in gene expression of heme oxygenase-1 (HO-1), which has an anti-proliferative effect associated with p21 up-regulation. Depletion of MsrB3 elevated HO-1 expression in mammalian cells, whereas MsrB3 overexpression had no effect. MsrB3 deficiency increased cellular reactive oxygen species (ROS), particularly in the mitochondria. ER stress, which is associated with up-regulation of HO-1, was also induced by depletion of MsrB3. Treatment with N-acetylcysteine as an ROS scavenger reduced augmented HO-1 levels in MsrB3-depleted cells. MsrB3 deficiency activated Nrf2 transcription factor by enhancing its expression and nuclear import. The activation of Nrf2 induced by MsrB3 depletion was confirmed by increased expression levels of its other target genes, such as γ-glutamylcysteine ligase. Taken together, these data suggest that MsrB3 attenuates HO-1 induction by inhibiting ROS production, ER stress, and Nrf2 activation.

Porcine methionine sulfoxide reductase B3: molecular cloning, tissue-specific expression profiles, and polymorphisms associated with ear size in Sus scrofa. J Anim Sci Biotechnol 2015; 6:60. [PMID: 26719797 PMCID: PMC4696113 DOI: 10.1186/s40104-015-0060-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2015] [Accepted: 12/21/2015] [Indexed: 12/02/2022] Open
Abstract
Background In Sus scrofa, methionine sulfoxide reductase B3 (MSRB3) is a crucial candidate gene for ear size, and an important conformational trait of pig breeds. However, challenges in MSRB3 cDNA amplification have prevented further identification of MSRB3 allelic variants influencing pig ear size. Results We cloned a full-length cDNA sequence of porcine MSRB3 by rapid-amplification of cDNA ends. The 3,765-bp gene contained a 5’-untranslated region (UTR) (190 bp), a coding region (552 bp), and a 3’-UTR (3,016 bp) and shared 84 %, 84 %, 87 %, 86 %, and 70 % sequence identities with human, orangutan, mouse, chicken, and zebrafish, respectively. The gene encoded a 183-amino acid protein, which shared 88 %, 91 %, 89 %, 86 %, and 67 % identities with human, orangutan, mouse, chicken, and zebrafish, respectively. Tissue expression analysis using qRT-PCR revealed that MSRB3 was expressed in the heart, liver, lung, kidney, spleen, ear, muscle, fat, lymph, skeletal, and hypothalamic tissues. Three single nucleotide polymorphisms (SNPs) were identified in MSRB3: c.-735C > T in the 5’ flanking region, c.2571 T > C in the 3’-UTR, and a synonymous mutation of c.484 T > C in the coding region. The SNPs c.-735C > T and c.2571 T > C were significantly associated with ear size in a Large White × Minzhu F2 population other than in Beijing Black pigs. Subsequently, at SNP c.-735C > T, the mRNA of MSRB3 was significantly higher expressed in ears of individuals with the TT genotype (Minzhu) than those with CC (Large White). Conclusions The porcine MSRB3 owned a 3,765-bp full-length cDNA sequence and was detected to express in ear tissue. Two SNPs of this gene were shown to be significantly associated with ear size in a Large White × Minzhu intercross population instead of Beijing Black pig population. What’s more, the individuals with higher mRNA expression of MSRB3 have larger ear sizes. These results provide useful information for further functional analyses of MSRB3 influencing ear size in pigs.

Abstract
BACKGROUND Systematic approaches to functionally identify key players in microRNA (miRNA)-target networks regulating prostate cancer (PCa) proliferation are still missing. OBJECTIVE To comprehensively map miRNA regulation of genes relevant for PCa proliferation through phenotypic screening and tumor expression data. DESIGN, SETTING, AND PARTICIPANTS Gain-of-function screening with 1129 miRNA molecules was performed in five PCa cell lines, measuring proliferation, viability, and apoptosis. These results were integrated with changes in miRNA expression from two cohorts of human PCa (188 tumors in total). For resulting miRNAs, the predicted targets were collected and analyzed for patterns with gene set enrichment analysis, and for their association with biochemical recurrence free survival. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Rank product statistical analysis was used to evaluate miRNA effects in phenotypic screening and for expression differences in the prostate tumor cohorts. Expression data were analyzed using the significance analysis of microarrays (SAM) method and the patient material was subjected to Kaplan-Meier statistics. RESULTS AND LIMITATIONS Functional screening identified 25 miRNAs increasing and 48 miRNAs decreasing cell viability. Data integration resulted in 14 miRNAs, with aberrant expression and effect on proliferation. These miRNAs are predicted to regulate >3700 genes, of which 28 were found up-regulated and 127 down-regulated in PCa compared with benign tissue. Seven genes, FLNC, MSRB3, PARVA, PCDH7, PRNP, RAB34, and SORBS1, showed an inverse association to their predicted miRNA, and were identified to significantly correlate with biochemical recurrence free survival in PCa patients. CONCLUSIONS A systematic in vitro screening approach combined with in vivo expression and gene set enrichment analysis provide unbiased means for revealing novel miRNA-target links, possibly driving the oncogenic processes in PCa. PATIENT SUMMARY This study identified novel regulatory molecules, which impact on PCa proliferation and are aberrantly expressed in clinical tumors. Thus, our study reveals regulatory nodes with potential for therapy.

Abstract
OBJECTIVE Emerging evidence suggests that methionine oxidation can directly affect protein function and may be linked to cardiovascular disease. The objective of this study was to define the role of the methionine sulfoxide reductase A (MsrA) in models of vascular disease and identify its signaling pathways. APPROACH AND RESULTS MsrA was readily identified in all layers of the vascular wall in human and murine arteries. Deletion of the MsrA gene did not affect atherosclerotic lesion area in apolipoprotein E-deficient mice and had no significant effect on susceptibility to experimental thrombosis after photochemical injury. In contrast, the neointimal area after vascular injury caused by complete ligation of the common carotid artery was significantly greater in MsrA-deficient than in control mice. In aortic vascular smooth muscle cells lacking MsrA, cell proliferation was significantly increased because of accelerated G1/S transition. In parallel, cyclin D1 protein and cdk4/cyclin D1 complex formation and activity were increased in MsrA-deficient vascular smooth muscle cell, leading to enhanced retinoblastoma protein phosphorylation and transcription of E2F. Finally, MsrA-deficient vascular smooth muscle cell exhibited greater activation of extracellular signal-regulated kinase 1/2 that was caused by increased activity of the Ras/Raf/mitogen-activated protein kinase signaling pathway. CONCLUSIONS Our findings implicate MsrA as a negative regulator of vascular smooth muscle cell proliferation and neointimal hyperplasia after vascular injury through control of the Ras/Raf/mitogen-activated protein kinase kinase/extracellular signal-regulated kinase 1/2 signaling pathway.
