Peroxiredoxin1, a novel regulator of pronephros development, influences retinoic acid and Wnt signaling by controlling ROS levels. Sci Rep 2017; 7:8874. [PMID: 28827763 PMCID: PMC5567039 DOI: 10.1038/s41598-017-09262-6] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2017] [Accepted: 07/17/2017] [Indexed: 01/02/2023] Open
Abstract
Peroxiredoxin1 (Prdx1) is an antioxidant enzyme belonging to the peroxiredoxin family of proteins. Prdx1 catalyzes the reduction of H2O2 and alkyl hydroperoxide and plays an important role in different biological processes. Prdx1 also participates in various age-related diseases and cancers. In this study, we investigated the role of Prdx1 in pronephros development during embryogenesis. Prdx1 knockdown markedly inhibited proximal tubule formation in the pronephros and significantly increased the cellular levels of reactive oxygen species (ROS), which impaired primary cilia formation. Additionally, treatment with ROS (H2O2) severely disrupted proximal tubule formation, whereas Prdx1 overexpression reversed the ROS-mediated inhibition in proximal tubule formation. Epistatic analysis revealed that Prdx1 has a crucial role in retinoic acid and Wnt signaling pathways during pronephrogenesis. In conclusion, Prdx1 facilitates proximal tubule formation during pronephrogenesis by regulating ROS levels.

Edwards MJ, Hinds LA, Deane EM, Deakin JE. A review of complementary mechanisms which protect the developing marsupial pouch young. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2012; 37:213-220. [PMID: 22504164 DOI: 10.1016/j.dci.2012.03.013] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/25/2012] [Revised: 03/26/2012] [Accepted: 03/26/2012] [Indexed: 05/31/2023]
Abstract
Marsupials are born without a functioning adaptive immune system, into a non-sterile environment where they continue to develop. This review examines the extent of exposure of pouch young to microorganisms and describes the protective mechanisms that are complementary to adaptive immunity in the developing young. Complementary protective mechanisms include the role of the innate immune system and maternal protection strategies, such as immune compounds in milk, prenatal transfer of immunoglobulins, antimicrobial compounds secreted in the pouch, and chemical or mechanical cleaning of the pouch and pouch young.

Proteomic study of calpeptin-induced differentiation on calpain-interacting proteins of C2C12 myoblast. In Vitro Cell Dev Biol Anim 2012; 48:175-85. [PMID: 22271316 DOI: 10.1007/s11626-012-9484-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2011] [Accepted: 01/04/2012] [Indexed: 10/14/2022]
Abstract
Studies on skeletal muscle cell specification and development have demonstrated in the past that calpains interact with various transcriptional factors in regulating the cellular function. It has therefore, been assumed that transcriptional factors like myogenin, MyoD, Myf5, and MRF4 that are active during the myogenic differentiation might be affected and degraded by calpains. Therefore, to examine the biochemical adaptations of myoblasts during myocyte formation and muscle development comprehensively, the current study was designed to identify the effect of calpeptin (calpain inhibitors) on protein expression during differentiation of C2C12 mouse myoblast. Cells were proliferated to near 80% confluence under Dulbecco's modified eagle medium and differentiated further in 2% HS with 50 μM calpeptin. Incubated cells were collected at 0, 12, and 72 h and later the cell proteins were focused onto pH 4-7 IEF strip, followed by 12.5% SDS-PAGE. Obtained spots on the gels were compared and matched using commercial 2-DE analysis software and matched spots were identified by MALDI-ToF and/or Q-Tof systems. Conclusively, cell differentiation was observed to be active from 12 to 72 h however, calpeptin affected the differentiation process and cut down the rate of fusion by approximately 50%. Out of 41 proteins identified, 12 proteins were found to be upregulated where as 29 proteins were downregulated.

Protein profiling of human nonpigmented ciliary epithelium cell secretome: the differentiation factors characterization for retinal ganglion cell line. J Biomed Biotechnol 2011; 2011:901329. [PMID: 21860587 PMCID: PMC3157028 DOI: 10.1155/2011/901329] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2011] [Revised: 06/10/2011] [Accepted: 06/13/2011] [Indexed: 12/04/2022] Open
Abstract
The purpose of this paper was to characterize proteins secreted from the human nonpigmented ciliary epithelial (HNPE) cells, which have differentiated a rat retinal ganglion cell line, RGC-5. Undifferentiated RGC-5 cells have been shown to express several marker proteins characteristic of retinal ganglion cells. However, RGC-5 cells do not respond to N-methyl-D aspartate (NMDA), or glutamate. HNPE cells have been shown to secrete numbers of neuropeptides or neuroproteins also found in the aqueous humor, many of which have the ability to influence the activity of neuronal cells. This paper details the profile of HNPE cell-secreted proteins by proteomic approaches. The experimental results revealed the identification of 132 unique proteins from the HNPE cell-conditioned SF-medium. The biological functions of a portion of these identified proteins are involved in cell differentiation. We hypothesized that a differentiation system of HNPE cell-conditioned SF-medium with RGC-5 cells can induce a differentiated phenotype in RGC-5 cells, with functional characteristics that more closely resemble primary cultures of rat retinal ganglion cells. These proteins may replace harsh chemicals, which are currently used to induce cell differentiation.

Molecules 2011; 16:3048-65. [PMID: 21478820 PMCID: PMC6260641 DOI: 10.3390/molecules16043048] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2011] [Revised: 03/31/2011] [Accepted: 04/02/2011] [Indexed: 11/17/2022] Open
Abstract
RuXian-I has traditionally been used as a remedy for breast hyperplasia in the Inner Mongolia Autonomous Region of China. As a first step toward the investigation of biomarkers associated with RuXian-I treatment, a proteome-wide analysis of rat breast tissue was conducted. First, rat breast hyperplasia was induced by injection of estradiol and progesterone. After treatment with RuXian-I, there is a marked decrease in the hyperplasia, as can be shown by decreases in the nipple diameter and the pathological changes in breast. Subsequently, we used an approach that integrates size-based 2D-DIGE, MALDI-TOF/TOF-MS, and bioinformatics to analyze data from the control group, the model group and the RuXian-I treatment group. Using this approach, seventeen affected proteins were identified. Among these, 15 (including annexin A1, annexin A2, superoxide dismutase [Mn], peroxiredoxin-1, translationally-controlled tumor protein and α B-crystallin) were significantly up-regulated in the model group and down-regulated upon treatment with RuXian-I, and two (Tpil protein and myosin-4) have the opposite change trend. The expression of annexin A1 was confirmed using immunohistochemistry. The expression of superoxide dismutase (SOD) activity was confirmed biochemically. These results indicated that RuXian-I treats rat breast hyperplasia through regulation of cell cycle, immune system, metabolic, signal transduction, etc. The differential expressions of these proteins (annexin A1, superoxide dismutase [Mn], alpha B-crystallins and translationally controlled tumor protein, among others) were associated with occurrence and metastasis of breast cancer. These findings might provide not only far-reaching valuable insights into the mechanism of RuXian-I action, but also leads for prognosis and diagnosis of breast hyperplasia and breast cancer.

Abstract
Background Avian infectious bronchitis (IB) is one of the most serious diseases of economic importance in chickens; it is caused by the avian infectious coronavirus (IBV). Information remains limited about the comparative protein expression profiles of chicken embryonic tissues in response to IBV infection in ovo. In this study, we analyzed the changes of protein expression in trachea and kidney tissues from chicken embryos, following IBV infection in ovo, using two-dimensional gel electrophoresis (2-DE) coupled with matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry (MALDI-TOF-TOF MS). Results 17 differentially expressed proteins from tracheal tissues and 19 differentially expressed proteins from kidney tissues were identified. These proteins mostly related to the cytoskeleton, binding of calcium ions, the stress response, anti-oxidative, and macromolecular metabolism. Some of these altered proteins were confirmed further at the mRNA level using real-time RT-PCR. Moreover, western blotting analysis further confirmed the changes of annexin A5 and HSPB1 during IBV infection. Conclusions To the best of our knowledge, we have performed the first analysis of the proteomic changes in chicken embryonic trachea and kidney tissues during IBV infection in ovo. The data obtained should facilitate a better understanding of the pathogenesis of IBV infection.

Molecular analysis of tammar (Macropus eugenii) mammary epithelial cells stimulated with lipopolysaccharide and lipoteichoic acid. Vet Immunol Immunopathol 2008; 129:36-48.

Abstract
The immunological function of the metatherian mammary gland plays a crucial part in neonatal survival of the marsupial young. Marsupial pouch young do not develop adult like immune responses until just prior to leaving the pouch. The immune components of the maternal milk secretions are important during this vulnerable early post-partum period. In addition, infection of the mammary gland has not been recognized in metatherians, despite the ready availability of pathogens in the pouch. Regardless of which, little is known about the immunobiology of the mammary gland and the immune responses of mammary epithelial cells in metatherians. In this study, a molecular approach was utilized to examine the response of tammar (Macropus eugenii) mammary epithelial cells to Escherichia coli derived lipopolysaccharide (LPS) and Staphylococcus aureus derived lipoteichoic acid (LTA). Using custom-made cDNA microarrays, candidate genes were identified in the transciptome, which were involved in antigen presentation, inflammation, cell growth and proliferation, cellular damage and apoptosis. Quantification of mRNA expression of several of these candidate genes, along with seven other genes (TLR4, CD14, TNF-alpha, cathelicidin, PRDX1, IL-5 and ABCG2) associated with innate immunity in LPS and LTA challenged mammary epithelial cells and leukocytes, was assessed for up to 24 h. Differences in genes associated with cellular damage and pro-inflammatory cytokine production were seen between stimulated mammary epithelial cells and leukocytes. LTA challenge tended to result in lower level induction of pro-inflammatory cytokines, increased PRDX1 mRNA levels, suggesting increased oxidative stress, and increased CD14 expression, but in a non-TLR4-dependent manner. The use of functional genomic tools in the tammar identified differences in the response of tammar mammary epithelial cells (MEC) and leukocytes to challenge with LPS and LTA, and validates the utility of the approach. The results of this study are consistent with a model in which tammar mammary epithelial cells have the capacity to elicit a complex and robust immune response to pathogens.

Abstract
Marsupials are born in a relatively underdeveloped state and develop during a period of intensive maturation in the postnatal period. During this period, the young marsupial lacks a competent immune system, but manages to survive despite the potential of exposure to environmental pathogens. Passive immune transfer via the milk is one well-recognised strategy to compensate the neonate, but there also may be innate immune mechanisms in place. In this study, CD14 and Toll-like receptor 4 (TLR4), integral molecular components of pathogen recognition, were identified and characterised for the first time in a marsupial, the tammar wallaby (Macropus eugenii). Functional motifs of tammar CD14 and the toll/interleukin receptor (TIR) domain of TLR4 were highly conserved. The lipopolysaccharide (LPS) binding residues and the TLR4 interaction site of CD14 were conserved in all marsupials. The TIR signalling domain had 84% identity within marsupials and 77% with eutherians. Stimulation of adult tammar leukocytes resulted in the induction of a biphasic pattern of CD14 and TLR4 expression, and coincided with increased production of the pro-inflammatory cytokine TNF-alpha. Differential patterns of expression of CD14 and TLR4 were observed in tammar pouch young early in development, suggesting that early maturation of the innate immune system in these animals may have developed as an immune survival strategy to protect the marsupial neonate from exposure to microbial pathogens.
