DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 149:105057.

Abstract
Metallothioneins (MTs) are low-molecular weight cytoplasmic heavy metal binding proteins. MTs can regulate the concentration of essential or non-essential metals in organisms, and have many important biological functions, including detoxification, trace element metabolism, and anti-oxidation. In the present study, we cloned and characterized a metallothionein gene (designated as MmMT) from the hard clam Meretrix meretrix. The complete cDNA sequence of MmMT contained an open reading frame (ORF) of 629 bp, which encoded a protein of 76 amino acids with a predicted molecular mass of 7.66 kDa and a calculated theoretical isoelectric point of 7.24. MmMT is highly similar to previously identified MTs from other species, with typical metallothionein features such as a high cysteine residue content and the absence of histidine and aromatic residues. The mRNA transcripts of MmMT were prevalent in all the tested tissues, and the expression levels of MmMT were highest in the hepatopancreas and hemocytes. During the stimulation of Vibrio splendidus, the mRNA transcripts of MmMT in the hepatopancreas and hemocytes were significantly increased. The Escherichia coli overexpressing MmMT performed strong growth in the media supplemented with CdCl2 and CuSO4 compared to the control strains. These results provide useful information for further investigation of the functions of MmMT in metal detoxification and the innate immune system.

The Multifaceted Effects of Short-Term Acute Hypoxia Stress: Insights into the Tolerance Mechanism of Propsilocerus akamusi (Diptera: Chironomidae). INSECTS 2023; 14:800. [PMID: 37887812 PMCID: PMC10607839 DOI: 10.3390/insects14100800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 09/26/2023] [Accepted: 10/02/2023] [Indexed: 10/28/2023]
Abstract
Plenty of freshwater species, especially macroinvertebrates that are essential to the provision of numerous ecosystem functions, encounter higher mortality due to acute hypoxia. However, within the family Chironomidae, a wide range of tolerance to hypoxia/anoxia is displayed. Propsilocerus akamusi depends on this great tolerance to become a dominant species in eutrophic lakes. To further understand how P. akamusi responds to acute hypoxic stress, we used multi-omics analysis in combination with histomorphological characteristics and physiological indicators. Thus, we set up two groups-a control group (DO 8.4 mg/L) and a hypoxic group (DO 0.39 mg/L)-to evaluate enzyme activity and the transcriptome, metabolome, and histomorphological characteristics. With blue-black chromatin, cell tightness, cell membrane invagination, and the production of apoptotic vesicles, tissue cells displayed typical apoptotic features in the hypoxic group. Although lactate dehydrogenase (LDH), alcohol dehydrogenase (ADH), catalase (CAT), and Na+/K+ -ATPase (NKA) activities were dramatically enhanced under hypoxic stress, glycogen content, and superoxide dismutase (SOD) activities were significantly reduced compared to the control group. The combined analysis of the transcriptome and metabolome, which further demonstrated, in addition to carbohydrates, including glycogen, the involvement of energy metabolism pathways, including fatty acid, protein, trehalose, and glyoxylate cycles, provided additional support for the aforementioned findings. Lactate is the end product of glycogen degradation, and HIF-1 plays an important role in promoting glycogenolysis in acute hypoxic conditions. However, we discovered that the ethanol tested under hypoxic stress likely originates from the symbiodinium of P. akamusi. These results imply that some parameters related to energy metabolism, antioxidant enzyme activities, and histomorphological features may be used as biomarkers of eutrophic lakes in Chironomus riparius larvae. The study also provides a scientific reference for assessing toxicity and favoring policies to reduce their impact on the environment.

Abstract
Due to global warming, world water bodies have higher temperatures and lower oxygen concentrations that affect aquatic species including the white shrimp Litopenaeus vannamei. This species withstands these conditions, but the information of the physiological responses that allow them to survive are scarce. We analyzed the effects of high temperature, hypoxia, reoxygenation, and the combination of these factors on the relative expression of selected genes: HSF1, Hsp70, p53, TIGAR, HIF-1α, and VEGF1-3 in gills of L. vannamei. Additionally, glucose, lactate, NADP, and NADPH were determined. HSF1 was up-regulated in the high temperature and oxygen stress conditions, but Hsp70 was up-regulated only in reoxygenation at both temperatures. HIF-1α was also up-regulated by reoxygenation in both temperatures. Meanwhile, the VEGF genes were not altered by the stress conditions, since none of them changed expression drastically. p53 relative expression remained stable at the tested stress conditions, which prompts to the maintenance of antioxidant defenses. TIGAR expression was induced in normoxia and hypoxia at high temperature, which induced NADPH content helping to scavenge reactive oxygen species (ROS). Additionally, high temperature caused higher glucose and lactate content in normoxia and hypoxia, indicating carbohydrate mobilization and a switch to anaerobic metabolism. The results showed that HSF1, the anaerobic metabolism and the pentose phosphate pathway (PPP) are crucial for the shrimp response to these abiotic stress conditions and contribute to their survival.

Abstract
Hypoxia triggers diverse cell physiological processes, and the hypoxia inducible factors (HIFs) are a family of heterodimeric transcription factors that function as master regulators to respond to hypoxia in different cells. However, the knowledge about the hypoxic responses especially cell alteration mediated by HIFs under hypoxia stress is still limited in crustaceans. In the present study, a hypoxia-inducible factor-1α (HIF-1α) gene was identified (designed as EsHIF-1α). The relative mRNA expression level of EsHIF-1α was highest in hyalinocytes and lowest in granulocytes among three types of haemocytes in crabs. Hypoxia could significantly increase the EsHIF-1α protein expression level in haemocytes. Meanwhile, the proportion of hyalinocytes began to increase from 3 h post hypoxia treatment, and reached the highest level at 24 h. However, the opposite variation in proportion of granulocytes was observed under hypoxia stress. Further investigation showed that the inhibition of EsHIF-1α induced by KC7F2 (HIF-1α inhibitor) could lead to the significant decrease in the proportion of hyalinocytes under hypoxia stress, and also resulted in an increase of granulocytes proportion. While, after EsHIF-1α was activated by IOX4 (HIF-1α activator), the proportion of hyalinocytes was significantly up-regulated and the proportion of granulocytes was significantly down-regulated under post hypoxia treatment. These results collectively suggested that EsHIF-1α was involved in the regulation of proportion of three types of haemocytes induced by hypoxia stress, which provided vital insight into the understanding of the crosstalk between hypoxia and cell development in invertebrates.

Abstract
Tumor suppressing transcription factor p53 regulates multiple pathways including DNA repair, cell survival, apoptosis, and autophagy. The current work studies stress-induced activation of p53 in anoxic crayfish (Faxonius virilis). Relative levels of target proteins and mRNAs involved in the DNA damage response was measured in normoxic control and anoxic hepatopancreas and tail muscle. Phosphorylation levels of p53 was assessed using immunoblotting at sites known to be phosphorylated (Serine 15 and 37) in response to DNA damage or reduced oxygen signaling. The capacity for DNA binding by phospho-p53 was also measured, followed by transcript analysis of a potentially pro-apoptotic downstream target, the etoposide induced (ei24) gene. Following this, both inhibitor (MDM2) and activator (p19-ARF) protein levels in response to low oxygen stress were studied. The results showed an increase in p53 levels during anoxia in both hepatopancreases and tail muscle. Increased transcript levels of ei24, a downstream target of p53, support the activation of p53 under anoxic stress. Cytoplasmic accumulation of Ser-15 p-p53 was observed during anoxia when proteins from cytoplasmic and nuclear fractions were measured. Increased cytoplasmic concentration is known to initiate an apoptotic response, which can be assumed as a preparatory step to prevent autophagy. The results suggest that p53 might play a protective role in crayfish defense against low oxygen stress. Understanding how anoxia-tolerant organisms are able to protect against DNA damage could provide important clues towards survival under metabolic rate depression and preparation for recovery to minimize damage.

Abstract
We investigated cadmium (Cd) accumulation in muscles, gills and hepatopancreas of Litopenaeus vannamei following 48 h exposure to 5.25 mg/L, and depuration of Cd in these tissues on 1, 5 and 15 d post exposure. We also detected the expressions of metallothionein (MT), caspase-3 and p53 in hepatopancreas of shrimp exposed to 0, 5.25 and 10.5 mg/L Cd (the 24 h median lethal concentration, 24 h LC50) at 0, 3, 12, 24 and 48 h. Cd accumulated with high concentration in hepatopancreas, and low concentration in muscles. Cd depurated fast in hepatopancreas and gills. MT expression increased in a time-dependent manner after Cd exposure. The p53 and caspase-3 increased at 12 and 24 h in 10.5 mg/L group. In conclusion, the accumulation and depuration of Cd in three tissues were tissues-specific. The changes of the expressions of MT, p53 and caspase-3, were stress response of L. vannamei under Cd exposure.

Abstract
Bivalve mollusks are important aquatic organisms, which are used for biological monitoring because of their abundance, ubiquitous nature, and abilities to adapt to different environments. MicroRNAs (miRNAs) are small noncoding RNAs, which typically silence the expression of target genes; however, certain miRNAs directly or indirectly upregulate their target genes. They are rapidly modulated and play an essential role in shaping the response of organisms to stresses. Based on the regulatory function and rapid alteration of miRNAs, they could act as biomarkers for biotic and abiotic stress, including environmental stresses and contaminations. Moreover, mollusk, particularly hemocytes, rapidly respond to environmental changes, such as pollution, salinity changes, and desiccation, which makes them an attractive model for this purpose. Thus, bivalve mollusks could be considered a good animal model to examine a system's response to different environmental conditions and stressors. miRNAs have been reported to adjust the adaptation and physiological functions of bivalves during endogenous and environmental stressors. In this review, we aimed to discuss the potential mechanisms underlying the response of bivalves to stressors and how miRNAs orchestrate this process; however, if necessary, other organisms' response is included to explain specific processes.

Abstract
Brief pretreatment of cold shock at 13 °C for 3 min proved to be an inducer of heat shock protein 70 (HSP70) and improved stress tolerance as a molecular chaperone. With the improvement of air exposure tolerance, HSP70 in shrimp hemocytes was upregulated in mRNA and protein levels after cold shock. Both HSP70 RNA interference (RNAi) gene knockdown and recombinant HSP70 (rHSP70) injection were successfully established in order to investigate the role of HSP70 in response to air exposure stress. Shrimp receiving rHSP70 showed an improved survival rate (80%) with no significant difference (p > 0.05) compared to cold shock treated shrimp (control, 90%) under air exposure, but the survival rate of HSP70-knockdown shrimp was significantly lower (62%, p < 0.05). Reactive oxygen species (ROS) content, relative expression of cytochrome c, caspase-3 activity, and apoptosis rate in hemocytes of HSP70 enriched shrimp (i.e., cold shock and rHSP70 injection) were significantly lower (p < 0.05) than HSP70-knockdown shrimp. Results suggested that HSP70 could be induced by cold shock and contributed to improve the tolerance of shrimp suffering air exposure by blocking the apoptosis pathway through scavenging intracellular ROS, inhibiting cytochrome c expression, inhibiting release from mitochondria, and inactivating caspase-3. This work updates the understanding of cold shock mechanism in water-free transportation of aquatic animals.

Abstract
miR-92a miRNAs are immune molecules that regulate apoptosis (programmed cell death) during the immune response. Apoptosis helps to maintain the dynamic balance in tissues of fish under hypoxia stress. The aim of this study was to explore the role and potential mechanisms of miR-92a in the liver of tilapia under hypoxia stress. We first confirmed that CaSR (encoding a calcium-sensing receptor) is a target gene of miR-92a in genetically improved farmed tilapia (GIFT) using luciferase reporter gene assays. In GIFT under hypoxia stress, miR-92a was up-regulated and CaSR was down-regulated in a time-dependent manner. Knocked-down CaSR expression led to inhibited expression of p53, TP53INP1, and caspase-3/8, reduced the proportion of apoptotic hepatocytes, and decreased the activity of calcium ions induced by hypoxia in hepatocytes. GIFT injected in the tail vein with an miR-92a agomir showed up-regulation of miR-92a and down-regulation of CaSR, p53, TP53INP1, and caspase-3/8 genes in the liver, resulting in lower serum aspartate aminotransferase and alanine aminotransferase activities under hypoxia stress. These findings suggest that stimulation of miR-92a interferes with hypoxia-induced apoptosis in hepatocytes of GIFT by targeting CaSR, thereby alleviating liver damage. These results provide new insights into the adaptation mechanisms of GIFT to hypoxia stress.

Abstract
Shrimp are increasingly exposed to warmer temperatures and lower oxygen concentrations in their habitat due to climate change. These conditions may lead to oxidative stress and apoptosis. We studied the effects of high temperature, hypoxia, reoxygenation, and the combination of these factors on lipid peroxidation, protein carbonylation, and caspase-3 activity in gills of white shrimp Litopenaeus vannamei. Silencing of mitochondrial manganese superoxide dismutase (mMnSOD) was used to determine the role of this enzyme in response to the abiotic stressors described above, to avoid oxidative damage and apoptosis. In addition, mMnSOD gene expression and mitochondrial SOD activity were evaluated to determine the efficiency of silencing this enzyme. The results showed that there was no effect of the abiotic stress conditions on the thiobarbituric acid reactive substances (TBARS), but protein carbonylation increased in all the oxidative stress treatments and caspase-3 activity decreased in hypoxia at 28 °C. On the other hand, mMnSOD-silenced shrimp experienced higher oxidative stress, since TBARS, carbonylated proteins and caspase-3 activity increased in some silenced treatments. Unexpectedly, mitochondrial SOD activity increased in some of the silenced treatments as well. Altogether, these results suggest that mMnSOD has a key role in shrimp for the prevention of oxidative damage development and induction of apoptosis in response to hypoxia, reoxygenation, high temperature, and their interactions, as conditions derived from climate change.

Abstract
Recently, we reported that hypoxia disrupts the endocrine system and causes metabolic abnormalities in prawns. Although transgenerational impairment effects of hypoxia have become a hot topic in vertebrate, it is unknown whether hypoxia could exert cross-generational effects on testicular function crustaceans. The present study aimed to investigate hypoxia's toxic effects on the testicular function of oriental river prawns (Macrobrachium nipponense) and offspring development. Hypoxia disrupted testicular germ cells quality, caused sex hormone imbalance (testosterone and estradiol), and delayed testicular development. The F1 generation derived from male prawns exposed to hypoxia showed retarded embryonic development, and reduced hatching success and larval development, despite not being exposed to hypoxia. Analysis of the transcriptome the F0 generation (exposed to hypoxia) showed that the impaired testicular functions were associated with changes to mitochondrial oxidative phosphorylation, apoptosis, and steroid biosynthesis. Interestingly, quantitative real-time PCR confirmed that hypoxia could significantly suppress the expression of antioxidant and gonad development-related genes in the testis of the F1 generations, with and without continued hypoxia exposures. In addition, paternal exposure to hypoxia could result in a higher production of reactive oxygen species in offspring testis tissue compared with those without hypoxia exposure. The cross-generational effects of testicular function implied that the sustainability of natural freshwater prawn populations would be threatened by chronic hypoxia.

Abstract
In the present study, a fas apoptotic inhibitory molecule (FAIM) was identified from Ruditapes philippinarum (designated as RpFAIM). Multiple alignments and phylogenetic analysis strongly suggested that RpFAIM was a new member of the FAIMs family. The RpFAIM transcripts were constitutively expressed in a wide range of tissues, and dominantly expressed in hemocytes. After V. anguillarum or M. luteus challenge, the expression level of RpFAIM transcripts was significantly induced and reached the maximum level at 6 h and 24 h, respectively. Knockdown of RpFAIM down-regulated the transcript levels of NF-κB signaling genes (e.g. RpIKK, RpIκB, RpNF-κB). The results were roughly similar to those under bacterial stimulation. Moreover, RpFAIM primarily localized in the cell cytoplasm, and its over-expression inhibited the apoptosis of HeLa cells. These results revealed that RpFAIM perhaps regulated the NF-κB signaling pathways positively, which provided a better understanding of RpFAIM in innate immunity.

Abstract
In fish under hypoxia stress, homeostasis can become imbalanced, leading to tissue and organ damage and decreased survival. Therefore, it is useful to explore the molecular and physiological regulation mechanisms that function in fish under hypoxia stress. The microRNA miR-34a is involved in fat and glycogen metabolism, and in apoptosis. In this study, we first verified that GLUT1, the gene encoding glucose transporter 1, is a potential target gene of miR-34a in genetically improved farmed tilapia (GIFT, Oreochromis niloticus) by dual luciferase reporter assays. Then, we clarified the regulatory relationship between miR-34a and GLUT1 by qRT-PCR analyses. We analyzed the regulatory effects of knockdown or promotion of GLUT1 expression in vitro and in vivo in GIFT under hypoxia stress. The results confirm that GLUT1 is a target gene of miR-34a in GIFT. Down-regulation of miR-34a significantly promoted GLUT1 expression. Knockdown of GLUT1 reduced the glycogen content in GIFT liver cells, inhibited HIF-1a gene expression, up-regulated the expression of genes involved in P53 signaling pathways (P53 and CASPASE-3 genes), and accelerated hepatocyte apoptosis under hypoxia stress. Compared with the control group, the group injected in the tail vein with miR-34a antagomir showed up-regulated expression of GLUT1 in the liver, increased liver glycogen content at 96 h of hypoxia stress, down-regulated expression of P53 and CASPASE-3, and decreased serum aspartate aminotransferase and alanine aminotransferase enzyme activities. Our results provide information about the molecular regulation mechanism of miRNAs and their target genes in fish during the response to hypoxia stress.

Abstract
Nitrite accumulation in aquatic environments is a potential risk factor that disrupts multiple physiological functions in aquatic animals. In this study, the physiology, transcriptome and metabolome of the control group (LV-C), nitrite-tolerance group (LV-NT) and nitrite-sensitive group (LV-NS) were investigated to identify the stress responses and mechanisms underlying the nitrite tolerance of Litopenaeus vannamei. After LV-NT and LV-NS were subjected to nitrite stress, the hemocyanin contents were significantly decreased, and hepatopancreas showed severe histological damage compared with LV-C. Likewise, the antioxidant enzymes were also significantly changed after nitrite exposure. The transcriptome data revealed differentially expressed genes associated with immune system, cytoskeleton remodeling and apoptosis in LV-NT and LV-NS. The combination of transcriptomic and metabolomic analysis revealed nitrite exposure disturbed metabolism processes in L. vannamei, including amino acid metabolism, nucleotide metabolism and lipid metabolism. The multiple comparative analysis implicated that higher nitrite tolerance of LV-NT than LV-NS may be attributed to enhanced hypoxia inducible factor-1α expression to regulate energy supply and gaseous exchange. Moreover, LV-NT showed higher antioxidative ability, detoxification gene expression and enhanced fatty acids contents after nitrite exposure in relative to LV-NS. Collectively, all these results will greatly provide new insights into the molecular mechanisms underlying the stress responses and tolerance of nitrite exposure in L. vannamei.

Abstract
Hypoxia is a common stressor for aquaculture species. The Pacific white shrimp Litopenaeus vannamei survives low dissolved oxygen (DO) conditions by adjusting its energy metabolism. In vertebrates, the transcription factor p53 regulates glucose metabolism under stress through diverse target genes like the Tp53-induced glycolysis and apoptotic regulator (TIGAR), a protein similar to fructose-2,6-bisphosphatase that has a pro-survival role in cells participating in the defense against oxidative damage. Until now, TIGAR has been not reported in any invertebrate species, including crustaceans. In this work, we report the molecular cloning of the white shrimp TIGAR. The cDNA sequence is 765 bp encoding a 254 amino acid protein. Bioinformatics analyses predicted that although the overall sequence identities of L. vannamei TIGAR and vertebrate proteins are not very high (33.61%-35.34%), they have a remarkable predicted structural similarity with full conservation of catalytic residues, secondary and three-dimensional structures. Gene expression analysis by RT-qPCR revealed that the mRNA abundance of TIGAR in white shrimp is tissue-specific under normal oxygen conditions, with higher expression in gills than hepatopancreas and muscle. Also, gene expression in gills and hepatopancreas is modified by environmental hypoxia, suggesting that TIGAR participates in the cellular tolerance of L. vannamei to this stressor.

Abstract
The present study aimed to evaluate the biological responses of Colossoma
macropomum to naphthalene injection and subsequent hypoxia
exposure, emphasizing the expression of the tumor suppressor gene
tp53. Tambaquis were intraperitoneally injected with
naphthalene (50 mg/kg) and, after 96 hours, the fish were transferred to
respirometry chambers and, submitted to progressive hypoxia for the
determination of critical PO2. In a subsequent experiment, the fish
received an intraperitoneal injection of naphthalene and were kept for 96 hours
under normoxia. Successively, fish were challenged with acute hypoxia
(PO2<PO2 crit) during 6 hours. We observed that the
PO2 crit was not affected by naphthalene injection. Moreover,
hematological parameters were modulated only in response to hypoxia. Fish with
naphthalene injection plus hypoxia exposure presented altered activity of the
GST and CAT enzymes. Exposure to naphthalene also resulted in DNA damages, which
was not influenced by hypoxia. Hypoxia accentuated the hepatic lesions caused by
naphthalene, as well as it also impaired the transcription of
tp53 in naphtalene injected fish, demonstrating the risks
of contaminating aquatic environments, especially environments where hypoxic
conditions are common and occur on a daily or on seasonal basis, as in the
Amazon basin.

Abstract
Autophagy, a crucial process for maintaining cellular homeostasis, is under the control of several autophagy-related (ATG) proteins, and is highly conserved in most animals, but its response to adverse environmental conditions is poorly understood in crustaceans. Herein, we hypothesised that autophagy acts as a protective response to hypoxia, and Beclin 1, ATG7 and ATG8 in oriental river prawn (Macrobrachium nipponense) were chosen as potential biomarkers under hypoxia exposure; thus, their full-length cDNA sequences were cloned and characterised. Open reading frames (ORFs) of 1281, 2076 and 360 bp, encoding proteins of 427, 692 and 120 amino acid residues, respectively, were obtained. Phylogenetic analysis demonstrated the three M. nipponense proteins do not form a clade with vertebrate homologs. Protein and mRNA levels were investigated in different tissues and developmental stages, and all three were significantly upregulated in a time-dependent manner in the hepatopancreas following hypoxia stress. Biochemical and morphological analysis of hepatocytes revealed that hypoxia increased the abundance of hepatic autophagic vacuoles and stimulated anaerobic metabolism. RNA interference-mediated silencing of ATG8 significantly increased the death rate of M. nipponense juveniles under hypoxia stress conditions. Together, these results suggest that Beclin 1, ATG7 and ATG8 contribute to autophagy-based responses against hypoxia in M. nipponense. The findings also expand our understanding of the potential role of autophagy as an adaptive response against hypoxia toxicity in crustaceans. The results showed that hepatic ATG8 levels may be directly indicative of acute hypoxia in prawns, and provide insight into the time at which hypoxia exposure occurs. Autophagy-related genes expression pattern seems to be sensitive and good biomarkers of acute hypoxia exposure.

Abstract
Hypoxia is one of the most common physiological stressors in shrimp farming. Post-transcriptional regulation by microRNAs has been recognized as a ubiquitous strategy to enable transient phenotypic plasticity and adaptation to stressful environment, but involvement of microRNAs in hypoxia stress response of penaeid shrimp remains elusive. In this study, small RNA sequencing and comparative transcriptomic analysis was conducted to construct a comprehensive microRNA dataset for the whiteleg shrimp Litopenaeus vannamei exposed to hypoxia challenge. A total of 3324 known miRNAs and 8 putative novel miRNAs were identified, providing a valuable resource for future investigation on the functional mechanism of miRNAs in shrimp. Upon hypoxia, 1213 miRNAs showed significant differential expression, and many well-known miRNAs involved in hypoxia tolerance such as miR-210, let-7, miR-143 and miR-101 were identified. Remarkably, the vast majority of these miRNAs were up-regulated, suggesting that up-regulation of miRNAs may represent an effective strategy to inhibit protein translation under stressful hypoxic condition. The differentially expressed miRNAs were potentially targeting a wide variety of genes, including those with essential roles in hypoxia tolerance such as HIF1a and p53. GO and KEGG enrichment analysis further revealed that a broad range of biological processes and metabolic pathways were over-represented. Several GO terms associated with gene transcription and translation and KEGG pathways related to cytoskeleton remodeling, immune defense and signaling transduction were enriched, highlighting the crucial roles of these cellular events in the adaptation to hypoxia. Taken together, our study revealed that the differentially expressed miRNAs may regulate host response to hypoxia by modulating the expression of stress response genes such as HIF1a and p53 and affecting key cellular events involved in hypoxia adaptation. The findings would expand our knowledge of the biochemical and molecular underpinnings of hypoxia response strategies used by penaeid shrimp, and contribute to a better understanding of the molecular mechanisms of hypoxia tolerance in decapod crustaceans.

Abstract
As invertebrates, shrimps rely on multiple innate defense reactions, including humoral immunity and cellular immunity to recognize and eliminate various invaders, such as viruses. White spot syndrome virus (WSSV) causes the most prevalent and devastating viral disease in penaeid shrimps, which are the most widely cultured species in the coastal waters worldwide. In the last couple of decades, studies about WSSV implicate a dual role of the immune system in protecting shrimps against the infection; these studies also explore on the pathogenesis of WSSV infection. Herein, we review our current knowledge of the innate immune responses of shrimps to WSSV, as well as the molecular mechanisms used by this virus to evade host immune responses or actively subvert them for its own benefit. Deciphering the interactions between WSSV and the shrimp host is paramount to understanding the mechanisms that regulate the balance between immune-mediated protection and pathogenesis during viral infection and to the development of a safe and effective WSSV defensive strategy.

Ageing reduces the reproductive performance of male white shrimp Litopenaeus vannamei by altering sperm intracellular Ca 2+ concentrations and interfering with sperm apoptosis. Anim Reprod Sci 2018; 198:74-81. [PMID: 30217679 DOI: 10.1016/j.anireprosci.2018.09.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2018] [Revised: 08/28/2018] [Accepted: 09/04/2018] [Indexed: 12/29/2022]
Abstract
Although the effects of age on the reproductive performance of various invertebrates, including white shrimp Litopenaeus vannamei are increasingly well documented, the mechanisms manifesting these impacts remain poorly understood. To ascertain the mechanisms of age on reproductive performance, the sperm quality, intracellular contents of Ca2+, insemination and hatching rates, and status of sperm apoptosis in terms of the expression of key regulatory genes were investigated in 11 and 16 month old male L. vannamei. The aged male individuals (16 months) had lesser reproductive performance in terms of fertilization and hatching rates. In addition, fewer and less viable sperm were detected in aged shrimp, which may be due to the altered expression of apoptosis-related genes. Furthermore, the aged males had lesser intracellular contents of Ca2+ in the sperm which may decrease the capacity of these gametes to undergo a complete acrosome reaction. In general, due to the decrease in intracellular contents of Ca2+ and alterations in the process of apoptosis, aged L. vannamei have relatively lesser quality sperm and may, therefore, have lesser reproductive performance.

Abstract
Some marine crustaceans like the white shrimp Litopenaeus vannamei are tolerant to environmental hypoxia. Under oxygen deprivation, shrimp tissues obtain energy by enhancing anaerobic glycolysis. In mammals, hypoxia increases the expression of the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH), which has been shown a "moonlighting" role in cells. However, the effect of hypoxia on the GAPDH expression has not been studied in crustaceans. In the present work, we obtained a 2744 bp gene sequence with a 999 bp ORF split by a single intron. The deduced protein is 332 amino acids and corresponds to the L. vannamei GAPDH (LvGAPDH), which is highly similar in sequence and structure to other animal GAPDHs. During hypoxia, LvGAPDH expression is significantly induced in gills but not in hepatopancreas, suggesting that it may play a role in the molecular and cellular response of shrimp to hypoxia.

Cell cycle regulation and apoptosis mediated by p53 in response to hypoxia in hepatopancreas of the white shrimp Litopenaeus vannamei. CHEMOSPHERE 2018; 190:253-259.

Abstract
Although hypoxic aquatic environments cause negative effects on shrimp, these animals can withstand somewhat hypoxia, but the cellular mechanisms underlying this capacity are still poorly understood. In humans, mild hypoxia causes the induction of many proteins to allow cell survival. In contrast, apoptosis is induced during severe hypoxia leading to cell death. p53 is a key transcription factor that determines cells fate towards cell cycle arrest or induction of apoptosis in humans. The aim of this work was to study the role of p53 in cell cycle regulation and apoptosis in response to hypoxia in hepatopancreas of the white shrimp Litopenaeus vannamei. p53 was silenced by RNAi and afterwards the shrimp were exposed to hypoxia. Cdk-2 was used as indicator of cell cycle progression while caspase-3 expression and caspase activity were analyzed as indicators of apoptosis. p53 levels in hepatopancreas were significantly higher at 48 h after hypoxic treatment. Increased expression levels of Cdk-2 were found in p53-silenced shrimp after 24 and 48 h in the normoxic treatments as well as 48 h after hypoxia, indicating a possible role of p53 in cell cycle regulation. In response to hypoxia, unsilenced shrimp showed an increase in caspase-3 expression levels, however an increase was also observed in caspase activity at 24 h of normoxic conditions in p53-silenced shrimps. Taken together these results indicate the involvement of p53 in regulation of cell cycle and apoptosis in the white shrimp in response to hypoxia.

Identification of two p53 isoforms from Litopenaeus vannamei and their interaction with NF-κB to induce distinct immune response. Sci Rep 2017; 7:45821.

Abstract
p53 is a transcription factor with capability of regulating diverse NF-κB dependent biological progresses such as inflammation and host defense, but the actual mechanism remains unrevealed. Herein, we firstly identified two novel alternatively spliced isoforms of p53 from Litopenaeus vannamei (LvΔNp53 and the full-length of p53, LvFLp53). We then established that the two p53 isoforms exerted opposite effects on regulating NF-κB induced antimicrobial peptides (AMPs) and white spot syndrome virus (WSSV) immediate-early (IE) genes expression, suggesting there could be a crosstalk between p53 and NF-κB pathways. Of note, both of the two p53 isoforms could interact directly with LvDorsal, a shrimp homolog of NF-κB. In addition, the activation of NF-κB mediated by LvDorsal was provoked by LvΔNp53 but suppressed by LvFLp53, and the increased NF-κB activity conferred by LvΔNp53 can be attenuated by LvFLp53. Furthermore, silencing of LvFLp53 in shrimp caused higher mortalities and virus loads under WSSV infection, whereas LvΔNp53-knockdown shrimps exhibited an opposed RNAi phenotype. Taken together, these findings present here provided some novel insight into different roles of shrimp p53 isoforms in immune response, and some information for us to understand the regulatory crosstalk between p53 pathway and NF-κB pathway in invertebrates.
