Abstract
SIGNIFICANCE Decrypting the cellular response to oxidative stress relies on a comprehensive understanding of the redox signaling pathways stimulated under oxidizing conditions. Redox signaling events can be divided into upstream sensing of oxidants, midstream redox signaling of protein function, and downstream transcriptional redox regulation. Recent Advances: A more and more accepted theory of hydrogen peroxide (H2O2) signaling is that of a thiol peroxidase redox relay, whereby protein thiols with low reactivity toward H2O2 are instead oxidized through an oxidative relay with thiol peroxidases. CRITICAL ISSUES These ultrareactive thiol peroxidases are the upstream redox sensors, which form the first cellular port of call for H2O2. Not all redox-regulated interactions between thiol peroxidases and cellular proteins involve a transfer of oxidative equivalents, and the nature of redox signaling is further complicated through promiscuous functions of redox-regulated "moonlighting" proteins, of which the precise cellular role under oxidative stress can frequently be obscured by "polygamous" interactions. An ultimate goal of redox signaling is to initiate a rapid response, and in contrast to prokaryotic oxidant-responsive transcription factors, mammalian systems have developed redox signaling pathways, which intersect both with kinase-dependent activation of transcription factors, as well as direct oxidative regulation of transcription factors through peroxiredoxin (Prx) redox relays. FUTURE DIRECTIONS We highlight that both transcriptional regulation and cell fate can be modulated either through oxidative regulation of kinase pathways, or through distinct redox-dependent associations involving either Prxs or redox-responsive moonlighting proteins with functional promiscuity. These protein associations form systems of crossregulatory networks with multiple nodes of potential oxidative regulation for H2O2-mediated signaling.

Abstract
The thioredoxin (Trx) system plays essential roles in maintenance and regulation of the redox state of cysteine residues in cellular proteins. The Trx-interacting protein (TXNIP) is a TRX inhibitory protein that works as a negative regulator in the TRX system. The function of TXNIP in invertebrates, in particular in immunity, remains unclear to date. In the current study, a novel TXNIP from Pacific white shrimp Litopenaeus vannamei was identified and characterized and its roles in immune responses was investigated. TXNIP could interact with Trx and inhibit its redox regulatory activity, suggesting that TXNIP was involved in regulation of the cellular redox state in shrimp. The expression of TXNIP was high in the stomach, gill, scape, eyestalk, epithelium, pyloric and muscle and low in the hepatopancreas, intestine, nerve, hemocytes and heart. Stimulations with pathogens white spot syndrome virus (WSSV) and Vibrio parahaemolyticus and immune stimulants poly (I:C) and LPS could significantly increase the expression of TXNIP in vivo. Silencing of TXNIP using RNAi strategy significantly facilitated the infection of V. parahaemolyticus but inhibited the infection of WSSV in shrimp. These indicated that TXNIP could be positively involved in antibacterial responses but negatively involved in antiviral responses in shrimp. Moreover, knockdown of TXNIP in vivo exerted opposite effects on expression of antimicrobial peptides anti-lipopolysaccharide factors and penaeidins and enhanced the phagocytic activity of hemocytes against bacteria. These suggested that TXNIP could play a complex role in regulation of humoral and cellular immune responses in shrimp.

Abstract
The thioredoxin system plays essential roles in maintenance and regulation of the redox state of cysteine residues in cellular proteins. The thioredoxin-related protein of 14 kDa (TRP14) is an important member of the TRX superfamily which acts on various substrate proteins, some of which are not overlapped with those of thioredoxin. The knowledge on the function of TRP14 in invertebrates is limited to date. In this study, a TRP14 gene was identified from Pacific white shrimp Litopenaeus vannamei (LvTRP14) and its role in immune responses was investigated. We demonstrated that the expression level of LvTRP14 was high in hepatopancreas and intestine, low in eyestalk, and medium in other tissues of healthy shrimp. The transcription of LvTRP14 in vivo was significantly down-regulated in Relish-silencing shrimp but up-regulated in STAT-silencing shrimp, indicating a complex regulation of LvTRP14 expression. Although the LvTRP14 expression showed little change after immune stimulation with different type of pathogens, knockdown of LvTRP14 expression using RNAi strategy could significantly facilitate the infection of white spot syndrome virus (WSSV) and Vibrio parahaemolyticus in shrimp. Dual luciferase reporter assays demonstrated that LvTRP14 enhanced the transcription factor activity of Relish but attenuated that of Dorsal. Furthermore, silencing of LvTRP14 in vivo had opposite effects on expression of different type of antimicrobial peptides. These suggested that LvTRP14 could play a complex role in shrimp immunity.

ACTA CRYSTALLOGRAPHICA SECTION D-STRUCTURAL BIOLOGY 2017; 73:326-339. [PMID: 28375144 DOI: 10.1107/s2059798317002066] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2016] [Accepted: 02/08/2017] [Indexed: 11/10/2022]
Abstract
The quaternary structure of the redox protein thioredoxin (Trx) has been debated. For bacterial Trx, there is no question regarding its monomeric state. In humans and other eukaryotes, the presence of a cysteine residue at the crystallographic symmetry axis points to the relevance of dimer formation in solution and in vivo. Crystallographic data for shrimp thioredoxin (LvTrx) obtained under different redox conditions reveal a dimeric arrangement mediated by a disulfide bond through residue Cys73 and other hydrophobic interactions located in the crystallographic interface, as reported for human Trx. Through the analysis of five mutants located at the crystallographic interface, this study provides structural and biochemical evidence for the existence in solution of monomeric and dimeric populations of wild-type LvTrx and five mutants. Based on the results of biochemical assays, SAXS studies and the crystallographic structures of three of the studied mutants (Cys73Ser, Asp60Ser and Trp31Ala), it is clear that the Cys73 residue is essential for dimerization. However, its mutation to Ser produces an enzyme which has similar redox activity in vitro to the wild type. A putative regulatory function of dimerization is proposed based on structural analysis. Nonetheless, the biological role of LvTrx dimerization needs to be experimentally unveiled. Additionally, the findings of this work reopen the discussion regarding the existence of similar behaviour in human thioredoxin, which shares a Cys at position 73 with LvTrx, a structural feature that is also present in some Trxs from vertebrates and crustaceans.
