Abstract
The white shrimp Penaeus (Litopenaeus) vannamei is the most cultivated shrimp worldwide. Compared to other shrimp species, it has higher resistance to adverse conditions. During hypoxia, the shrimp reduces oxygen consumption and adjusts energy metabolism via anaerobic glycolysis, among other strategies. Hexokinase (HK) is the first enzyme of glycolysis and a key regulation point. In mammals and other vertebrates, there are several tissue-specific HK isoforms with differences in expression and enzyme activity. In contrast, crustacean HKs have been relatively little studied. We studied the P. vannamei HK isoforms during hypoxia and reoxygenation. We cloned two HK1 sequences named HK1-long (1455 bp) and HK1-short (1302 bp), and one HK2 (1344 bp). In normoxia, total HK1 expression is higher in hepatopancreas, while HK2 is higher in gills. Severe hypoxia (1 mg/L of DO) after 12 h exposure and 1 h of reoxygenation increased HK1 expression in both organs, but HK2 expression changed differentially. In hepatopancreas, HK2 expression increased in 6 and 12 h of hypoxia but diminished to normoxia levels after reoxygenation. In gills, HK2 expression decreased after 12 h of hypoxia. HK activity increased in hepatopancreas after 12 h hypoxia, opposite to gills. These results indicate that shrimp HK isoforms respond to hypoxia and reoxygenation in a tissue-specific manner. Intracellular glucose levels did not change in any case, showing the shrimp ability to maintain glucose homeostasis during hypoxia.

Abstract
Salinity and temperature influence growth, survival, and reproduction of crustacean species such as Penaeus vannamei where Na +/K+-ATPase plays a key role in maintaining osmotic homeostasis in different salinity conditions. This ability is suggested to be mediated by other proteins including neuropeptides such as the crustacean hyperglycemic hormones (CHHs), and heat shock proteins (HSPs). The mRNA expression of Na+/K+-ATPase, HSP60, HSP70, CHH-A, and CHH-B1, was analyzed by qPCR in shrimp acclimated to different salinities (10, 26, and 40 PSU) and temperature conditions (20, 23, 26, 29, and 32 °C) to evaluate their uses as molecular stress biomarkers. The results showed that the hemolymph osmoregulatory capacity in shrimp changed with exposure to the different salinities. From 26 to 32 °C the Na+/K+-ATPase expression increased significantly at 10 PSU relative to shrimp acclimated at 26 PSU and at 20 °C increased at similar values independently of salinity. The highest HSP expression levels were obtained by HSP70 at 20 °C, suggesting a role in protecting proteins such as Na+/K+ -ATPase under low-temperature and salinity conditions. CHH-A was not expressed in the gill under any condition, but CHH-B1 showed the highest expression at the lowest temperatures and salinities, suggesting its participation in the Na+/K+-ATPase induction. Since Na+/K+-ATPase, HSPs, and CHHs seem to participate in maintaining the osmo-ionic balance and homeostasis in P. vannamei, their expression levels may be used as a stress biomarkers to monitor marine crustacean health status when acclimated in low salinity and temperature conditions.

Abstract
Persistent organic pollutants (POPs) are ubiquitous in marine ecosystems. These compounds can be accumulated in water, sediments and organisms, persist in time, and have toxic effects in human and wildlife. POPs can be uptaken and bioaccumulated by crustaceans, affecting different physiological processes, including energy metabolism, immunity, osmoregulation, excretion, growth, and reproduction. Nonetheless, animals have evolved sub-cellular mechanisms for detoxification and protection from chemical stress. POPs induce the activity of enzymes involved in xenobiotic metabolism and antioxidant systems, that in vertebrates are importantly regulated at gene expression (transcriptional) level. However, the activation and control of these enzyme systems upon the exposure to POPs have been scarcely studied in invertebrate species, including crustaceans. Herein, we summarize various aspects of the bioaccumulation of POPs in marine crustaceans and their physiological effects. We specially focus on the regulation of xenobiotics metabolism and antioxidant enzymes as key sub-cellular mechanisms for detoxification and protection from chemical stress.

Abstract
Hypoxia is a frequent stressor in marine environments with multiple adverse effects on marine species. The white shrimp Litopenaeus vannamei withstands hypoxic conditions by activating anaerobic metabolism with tissue-specific changes in glycolytic and gluconeogenic enzymes. In animal cells, glycolytic/gluconeogenic fluxes are highly controlled by the levels of fructose-2,6-bisphosphate (F-2,6-P2), a signal metabolite synthesized and degraded by the bifunctional enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase-2). PFK-2/FBPase-2 has been studied in vertebrates and some invertebrates, but as far as we know, there are no reports on PFK-2/FBPase-2 from crustaceans. In the present work, we obtained cDNA nucleotide sequences corresponding to two mRNAs for PFK-2/FBPase-2 and named them PFKFBP1 (1644 bp) and PFKFBP2 (1566 bp), from the white shrimp L. vannamei. The deduced PFKFBP1 and PFKFBP2 are 547 and 521 amino acids long, respectively. Both proteins share 99.23% of identity, and only differ in 26 additional amino acids present in the kinase domain of the PFKFBP1. The kinase and phosphatase domains are highly conserved in sequence and structure between both isoforms and other proteins from diverse taxa. Total expression of PFKFBP1-2 is tissue-specific, more abundant in gills than in hepatopancreas and undetectable in muscle. Moreover, severe hypoxia (1 mg/L of DO) decreased expression of PFKFBP1-2 in gills while anaerobic glycolysis was induced, as indicated by accumulation of cellular lactate. These results suggest that negative regulation of PFKFBP1-2 at expression level is necessary to set up anaerobic glycolysis in the cells during the response to hypoxia.

Abstract
Osmoregulation in crustaceans is under neuroendocrine control by the crustacean hyperglycemic hormones (CHHs), which modify water and ion concentrations in diverse species. Previous studies done by our group suggested that CHH variant B1 (CHH-B1) has effects on the osmoregulatory responses of the Pacific white shrimp Litopenaeus vannamei. For a better understanding of the molecular action mechanisms of CHH-B1 in osmoregulation, in this work, we established the dose-dependent effect of recombinant CHH-B1 on the gene expression of Na+/K+-ATPase (NKA) in gills, in contrast to changes in the osmoregulatory capacity (OC) of bilaterally eyestalk-ablated shrimp under hyper-osmotic conditions. The results indicate that CHH-B1 regulates the OC of shrimp during hypo-regulation by modulating Na+/K+-ATPase at a transcriptional level. Our results suggest that CHH has a direct participation in the control of osmo-ionic regulation mechanisms, not only in L. vannamei but in crustaceans in general.

Abstract
Low oxygen concentration in water (hypoxia) and high temperature are becoming more frequent due to climate change, forcing animals to endure stress or decease. Hypoxia and high temperature stress can lead to reactive oxygen species (ROS) accumulation and oxidative damage to the organisms. The shrimp Litopenaeus vannamei is the most cultivated crustacean worldwide. The aim of this study was to evaluate the expression and enzymatic activity of glutathione peroxidase (GPx), catalase (CAT) and cytosolic manganese superoxide dismutase (cMnSOD) in gills and hepatopancreas from L. vannamei in response to two combined stressors: hypoxia and reoxygenation at control and high temperature (28 vs 35 °C, respectively). In addition, glutathione and hydrogen peroxide content were analyzed. The changes were mainly tissue-specific. In gills, cMnSOD expression and enzymatic activity increased in response to the interactions between oxygen variation and thermal stress, while GPx and CAT were maintained. More changes occurred in GPx, CAT and MnSOD in hepatopancreas than in gills, mainly due to the effect of the individual stress factors of thermal stress or oxygen variations. On the other hand, the redox state of glutathione indicated that during high temperature, changes in the GSH/GSSG ratio occurred due to the fluctuations of GSSG. Hydrogen peroxide concentration was not affected by thermal stress or oxygen variations in hepatopancreas, whereas in gills, it was not detected. Altogether, these results indicate a complex pattern of antioxidant response to hypoxia, reoxygenation, high temperature and their combinations.

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 cell cycle comprises a series of steps necessary for cell growth until cell division. The participation of proteins responsible for cell cycle regulation, known as cyclin dependent kinases or Cdks, is necessary for cycle progression. Cyclin dependent kinase 2 (Cdk-2) is one of the most studied Cdks. This kinase regulates the passage through the G1/S phase and is involved in DNA replication in the S phase. Cdks have been extensively studied in mammals, but there is little information about these proteins in crustaceans. In the present work, the nucleotide and amino acid sequence of Cdk-2 from the white shrimp (Cdk-2) and its expression during hypoxia and reoxygenation are reported. Cdk-2 is a highly conserved protein and contains the serine/threonine catalytic domain, an ATP binding site and the PSTAIRE sequence. The predicted Cdk-2 structure showed the two-lobed structure characteristic of kinases. Expression of Cdk-2 was detected in hepatopancreas, gills and muscle, with hepatopancreas having the highest expression during normoxic conditions. Cdk-2 expression was significantly induced after hypoxia for 24 h in muscle cells, but in hypoxia exposure for 24 followed by 1 h of reoxygenation, the expression levels returned to the levels found in normoxic conditions, suggesting induction of cell cycle progression in muscular cells during hypoxia. No significant changes in expression of Cdk-2 were detected in these conditions in hepatopancreas and gills.

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.

Abstract
Crustacean hyperglycemic hormones (CHHs) are multifunctional neuropeptides ubiquitous in crustaceans. In Litopenaeus vannamei, CHH-B2 is a CHH eyestalk isoform whose expression has been shown to vary with enviromental conditions, suggesting its relevance for ecophysiological performance of shrimp, controlling processes related to metabolism and osmo-ionic regulation. To study the involvement of CHH-B2 in these processes, we cloned and expressed a recombinant version with a free C-terminal glycine (rCHH-B2-Gly) in the methylotrophic yeast Pichia pastoris. The rCHH-B2-Gly peptide secreted to the culture medium was purified by RP-HPLC and used for in vivo glucose, triglyceride, and osmoregulation dose-response analyses with juvenile shrimp. The peptide was also amidated at the C-terminus using an α-amidating enzyme to produce rCHH-B2-amide. The shrimp showed a dose-dependent effect of rCHH-B2-Gly to hemolymph glucose and triglyceride levels, inducing maximal increases by injecting 500 and 1000pmol of hormone, respectively. Additionally, 10pmol of hormone was sufficient to reduce the hypo-osmoregulatory capacity of shrimp at 35‰. These findings suggest that CHH-B2 has regulatory roles in carbohydrate and lipid metabolism, and a potential involvement in osmoregulation of L. vannamei. Injection of 100pmol of rCHH-B2-amide increased glucose and triglyceride levels by 15 and 28%, respectively in comparison with rCHH-B2-Gly, suggesting an important role for the C-terminal amidation. Additionally, an in silico structural analysis done with the CHH-B1 and rCHH-B2-Gly peptides suggests that the C-terminal region may be relevant for the activity of the L. vannamei isoforms and explain the functional divergence from other crustacean CHH/CHH-like peptides.

Abstract
Crustacean hyperglycemic hormone (CHH) is the most abundant neuropeptide produced by the X-organ/sinus gland (XO/SG) complex in the crustacean eyestalk. CHH plays a principal role in the control of glucose metabolism. The CHH-B1 isoform is produced in the eyestalk of Litopenaeus vannamei by alternative splicing of the chhB gene and its cDNA sequence has revealed that this isoform has a non-amidated C-terminal residue (CHH-like peptide). In this work, a recombinant CHH-B1 (rCHH-B1) with a sequence identical to the native hormone was expressed in the methylotrophic yeast Pichia pastoris X-33 and purified from the culture medium by RP-HPLC. The identity of the purified rCHH-B1 was confirmed by N-terminal sequencing and by using an anti-CHH-B1 polyclonal antibody. An in vivo assay showed that the hyperglycemic effect was dependant of the dosage of rCHH-B1, and the maximal hyperglycemic response was obtained with 250pmol treatment. These results suggest that the amino acid sequence of the C-terminus and its correct structure are both important for the hyperglycemic activity of naturally occurring non-amidated CHH peptides, such as CHH-B1. CHH-B1 appears to be the first reported CHH-like peptide with significant hyperglycemic activity produced in the sinus gland of a penaeid shrimp.
