Nervous necrosis virus (NNV), the causative agent of viral nervous necrosis (VNN) disease, has caused mass mortality of cultured marine and freshwater fish worldwide, resulting in enormous economic losses in the aquaculture industry. However, the molecular mechanisms underlying the pathogenicity of NNV are still poorly understood. In this study, the transcriptomic profiles of striped snakehead fish (Channa striatus) cells (SSN-1) infected with red-spotted grouper NNV (RGNNV) were investigated using deep RNA sequencing technique...

Heat shock proteins (HSPs) are immunogenic, ubiquitous class of molecular chaperones, which are induced in response to various environmental and microbial stressful conditions. It plays a vital role in maintaining cellular protein homeostasis in eukaryotic cells. In this study, we described a comprehensive comparative data by bioinformatics approach on three different full length cDNA sequences of HSP family at molecular level. The cDNA sequences of three HSPs were identified from constructed cDNA library of Channa striatus and named as CsCPN60, CsHSP60 and CsHSP70...

ETHNOPHARMACOLOGICAL RELEVANCE: Haruan, Channa striatus, is a freshwater fish which has been well-known locally to accelerate wound healing during post-operative and post-partum periods. The fish extract also has potent anti-inflammatory and analgesic properties. AIM OF THE STUDY: To assess topical anti-inflammatory effect of Haruan cream on 12-0-tetradecanoylphorbol-13-acetate (TPA)-induced chronic-like dermatitis in mice. MATERIALS AND METHODS: Male ICR mice were randomized into six groups of five mice each: acetone (vehicle), TPA alone (negative control), three Haruan treatment groups (Haruan 1%, Haruan 5% and Haruan 10%) and hydrocortisone 1% (positive control)...

Antimicrobial peptides (AMPs) are innate molecules that are found in a wide variety of species ranging from bacteria to humans. In recent years, excessive usage of antibiotics resulted in development of multi-drug resistant pathogens which made researchers to focus on AMPs as potential substitute for antibiotics. Lily type mannose-binding lectin is an extended super-family of structurally and evolutionarily related sugar binding proteins. These lectins are well-known AMPs which play important roles in fish defense mechanism...

Present investigation was carried out to study the histo-pathological alterations induced by metacercariae of digenetic trematode, Euclinostomum heretostomum on the kidney of Channa striatus and Channa marulius in natural condition. Histo-architectural alterations induced by parasite included reduced size of glomeruli, severe degeneration and necrosis of haemopoietic tissue and tubule cells with hypertrophied nuclei in C. striatus. Whereas, infected kidney of C. marulius exhibited the development of several melano-macrophage centers, hypertrophied nuclei of tubule cells and detached epithelial cells of renal tubules...

The present study was undertaken to investigate the proteomic changes in the liver of murrel Channa striatus exposed to high temperature stress. Fishes were exposed to 36°C for 4 days and liver proteome changes were analyzed using gel- based proteomics, i.e. 2DE, MALDI-TOF/TOF-MS, and validation by transcript analysis. The study showed, besides others, increased abundance of two sets of proteins, the antioxidative enzymes superoxide dismutase (SOD), ferritin, cellular retinol binding protein (CRBP), glutathione-S-transferase (GST), and the chaperones HSP60 and protein disulfide isomerase; this was validated by transcript analysis...

Epizootic Ulcerative Syndrome (EUS) caused by Aphanomyces invadans which is a primary fungal parasitic pathogen, inflicts serious economic loss in tropical freshwater fish including snakehead murrel, Channa striatus. In the present study with an aim to circumvent the adverse effects of the traditional measures in graded levels (2%, 4%, and 6%) of Zeolite enriched diet on growth performance, hematology, immunological response, and disease resistance in C. striatus against A. invadans is reported. The final weight (FW), specific growth rate (SGR), feed conversion ratio (FCR), protein efficiency ratio (PER), and average daily gain (ADG) were significantly high in infected fish fed with 4% or 6% Zeolite incorporated diets on 4th week...

Caspases are evolutionarily conserved proteases which play fundamental role in apoptosis. Invasion of pathogen triggers the activation of caspases-mediated pro-inflammatory and pro-apoptotic pathways, where multifunctional caspases are involved. In striped murrel Channa striatus, epizootic ulcerative syndrome (EUS) causes endemics resulting in huge economic loss. Aphanomyces invadans, an oomycete is the primary causative agent of EUS which further induces secondary bacterial infections especially Aeromonas hydrophila...

In aquaculture, accumulation of antibiotics resulted in development of resistance among bacterial pathogens. Consequently, it became mandatory to find alternative to synthetic antibiotics. Antimicrobial peptides (AMPs) which are described as evolutionary ancient weapons have been considered as promising alternates in recent years. In this study, a novel antimicrobial peptide had been derived from goose type lysozyme (LyzG) which was identified from the cDNA library of freshwater fish Channa striatus (Cs). The identified lysozyme cDNA contains 585 nucleotides which encodes a protein of 194 amino acids...

Quantitative real-time polymerase chain reaction is the most advanced method of quantifying gene expression studies; however, the significance of the obtained results strongly depends on the normalization of the data to compensate for differences between the samples. In the present study, expression analysis of six different constitutively expressed genes viz. 18S ribosomal RNA, glyceraldehyde-3-phosphate dehydrogenase (gapdh), beta actin (βactin), ribosomal binding protein L13, tubulin and TATA-box-binding protein (tbp) were carried out to test their efficacy as reference genes in three different tissues, namely liver, gill and muscle of murrel Channa striatus exposed to high temperature for variable time periods...

Heavy metals can significantly bioaccumulate in fish tissues. The step wise mechanism of heavy metal toxicities on fish health is still limited. The present study assessed the tissue-specific antioxidant response and oxidative stress biomarkers of commercially important fish species namely, Channa striatus and Heteropneustes fossilis inhabiting Kali River of northern India where heavy-metal load is beyond the World Health Organisation - maximum permissible limits. Heavy metals chromium (Cr), nickel (Ni), lead (Pb) and cadmium (Cd) were elevated in both fish species compared to recommended values of the Federal Environmental Protection Agency (FEPA), 1999 for edible fishes...

The establishment and characterization of a continuous cell line from the thymus of air-breathing fish Channa striatus are described. The cell line, designated C. striatus thymus (CST), has been subcultured over 71 times and shows optimal growth at 28°C in Leibovitz's-15 (L-15) medium supplemented with 20% fetal bovine serum. The CST cells exhibited low plating efficiency which improved with increase in seeding density. The karyotype analysis revealed that CST cells have a normal diploid karyotype with 2n = 40...

Cu/ZnSOD (copper/zinc superoxide dismutase) primarily scavenges cytosolic reactive oxygen species (ROS) by converting ROS to hydrogen peroxide, which is then converted to water by the catalytic action of catalase, thus playing a pivotal role in the first line of defense mechanism against oxidative stress. In this study, we have reported a complete molecular characterization of cDNA sequence from striped murrel Channa striatus (Cs). Cellular location prediction reveals that CsCu/ZnSOD protein is cytosolic with an accuracy of 90%...
