Comparative analysis of β-hexosaminidase and acid phosphatase from Hydra vulgaris Ind-Pune, H. vulgaris Naukuchiatal and H. magnipapillata sf-1: Localization studies of acid phosphatase and β-hexosaminidase from H. vulgaris Ind-Pune. Comp Biochem Physiol B Biochem Mol Biol 2019; 239:110365. [PMID: 31629812 DOI: 10.1016/j.cbpb.2019.110365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Revised: 09/08/2019] [Accepted: 09/18/2019] [Indexed: 11/25/2022]
Abstract
The present report describes a comprehensive study on comparative biochemical characterization of two lysosomal enzymes, acid phosphatase and β-hexosaminidase in three different strains of Hydra; Hydra vulgaris Ind-Pune, H. vulgaris Naukuchiatal and H. magnipapillata sf-1 (self-feeder-1). Since morphology and habitat of Hydra effect lysosomal enzymes and their response to environmental pollutants, it would be interesting to identify them in different Hydra strains so as to use them as toxicity testing. Preliminary studies revealed a differential expression of acid phosphatase, β-hexosaminidase and β-glucuronidase in three Hydra strains. Expression of all three lysosomal enzymes in H. vulgaris Ind-Pune was low in comparison to H. vulgaris Naukuchiatal and H. magnipapillata sf-1, while their expression is comparable in H. vulgaris Naukuchiatal and H. magnipapillata sf-1. The Michaelis-Menten (KM) values for lysosomal β-hexosaminidase using 4-nitrophenyl N-acetyl-β-D-glucosaminide as substrate were found to be 1.3 mM, 1.1 mM and 0.8 mM, respectively for H. vulgaris Ind-Pune, H. vulgaris Naukuchiatal and H. magnipapillata sf-1. For acid phosphatase using 4-nitrophenyl-phosphate as substrate, the KM values were 0.38 mM, 1.2 mM and 0.52 mM respectively, for H. vulgaris Ind-Pune, H. vulgaris Naukuchiatal and sf-1 strains. The optimum temperature for β-hexosaminidase was 60 °C for H. vulgaris Ind-Pune, while 50 °C was observed for H. vulgaris Naukuchiatal and sf-1 strains. The optimum pH for β-hexosaminidase was found to be 6.0 for H. vulgaris Ind-Pune and H. vulgaris Naukuchiatal, and 5.0 for sf-1. The optimum temperature and pH of acid phosphatase was similar in all three strains, viz., 40 °C and 3.0, respectively. Preliminary localization studies using whole mount in situ hybridization revealed predominant endodermal expression of three enzymes in H. vulgaris Ind-Pune. Our results thus support the conservation of lysosomal hydrolases in Hydra.

Vulnerability of marsh frog Pelophylax ridibundus to the typical wastewater effluents ibuprofen, triclosan and estrone, detected by multi-biomarker approach. Comp Biochem Physiol C Toxicol Pharmacol 2017; 202:26-38. [PMID: 28757214 DOI: 10.1016/j.cbpc.2017.07.004] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2017] [Revised: 07/23/2017] [Accepted: 07/25/2017] [Indexed: 11/24/2022]
Abstract
Pharmaceutical and personal care products (PPCPs) are the environmental pollutants of growing concern. The aim of this study was to indicate the effects of typical PPCPs on the marsh frog Pelophylax ridibundus. We treated male frogs with waterborne ibuprofen (IBU, 250ng·L-1), triclosan (TCS, 500ng·L-1), or estrone (E1, 100ng·L-1) for 14days. Common vulnerability of the frogs was detected from dramatic decrease of Zn, total and metalated metallothionein (MT) concentrations, Zn/Cu ratio, the elevation of activity of glutathione-S-transferase, cathepsin D and DNA instability in the liver, the depletion of cholinesterase in the brain and cortisol in the blood plasma in all exposures. Nevertheless, lipofuscin concentration in the liver was always decreased. The groups were best distinguished by cytochrome P450 (CYP450) activity determined by ELISA. The exposure to IBU caused lesser damage, but elevated the levels of oxyradicals and glutathione (GSH and GSSG) and lysosomal membrane instability. Exposures to TCS and E1 provoked the endocrine disturbance (increased levels of vitellogenin and thyrotropin in blood plasma), decreased lactate dehydrogenase activity and increased level of pyruvate in the liver. TCS caused the increase of GSSG by 7.3 times and lactate levels. Only E1 lead to decrease of deiodinase activity in the liver, activation of CYP450 and caspase-3 and efflux of cathepsin D from lysosomes. Spectrophotometric and ELISA assays of MTs and CYP450 gave distinct results in E1-group. Broad disruption of the hormonal pathways caused by E1 could be of concern for the health status of frogs in their habitats.

Abstract
Despite numerous studies suggesting a dramatic decline of amphibians, the biochemical mechanisms of adaptation in these animals to polluted environment are poorly studied. The aim of this study was to elucidate the ability to release cobalt (Co) and zinc (Zn) from their nanoscale complexes (NCs) derived from the polymeric substance of N-vinylpyrrolidone (PS) in the liver of amphibian (Rana ridibunda). Frog males were subjected to 14days exposure to waterborne Co(2+) (50μg/L), Zn(2+) (100μg/L), as well as corresponding concentrations of Co-NC, Zn-NC or PS. Main attention was paid to MT's interrelations with indices of stress and toxicity. Only Co(2+) and Zn(2+) caused elevation of the correspondent metal in MTs. Co(2+) caused down-regulation of cathepsin D activity, while Zn(2+), Zn-NC and the PS up-regulated this activity. Zn(2+) provoked 1.6 times increase of metal-bounded form of the MT (MT-Me), while all other exposures caused the elevation of the ratio of MT total protein concentration (MT-SH) and concentrations of the MT-Me and/or immunoreactive (MTi) form (up to ~10 times) accompanied by a decrease in the levels of oxyradicals. The increased DNA fragmentation and down-regulation of caspase-3 activity in relation to the redox state of glutathione and/or lactate/pyruvate were shown at all exposures. These data indicate the vulnerability of the redox state of cellular thiols and inability to release Co and Zn from NCs in frog's liver.

Abstract
Extracellular proteases and their inhibitors may regulate a number of important processes involved in forelimb regeneration in the adult newt, including epithelial remodeling, breakdown of extracellular matrix, and dedifferentiation. We have identified a newt homologue of human ElastaseI (NvElastaseI) and its potential inhibitor, SLPI (NvSLPI), and evaluated their spatial and temporal expression during limb regeneration. NvElastaseI is upregulated early in regeneration and is associated with subdermal and wound epithelial cells, suggesting an involvement in wound healing and the generation of the wound epithelium. Up until 15 days post-amputation, NvElastaseI is also scattered throughout the developing blastema and may have a role in the dedifferentiation of stump tissues. NvSLPI is found at the interface between the intact skin and the wound epithelium, and may limit NvElastaseI activity. NvSLPI is also expressed in dermal glands, and is likely involved in anti-microbial activity or function. Quite apart from regeneration, complementary patterns of expression of NvElastaseI and NvSLPI are associated with newt epithelial sloughing.

Abstract
The epicuticular surface protein Lma-p54 is imbedded in the "cuticular waxes" which cover the abdominal surface of the adult Leucophaea maderae. Natural Lma-p54 was purified and the complete cDNA sequence was determined by RT-PCR using primers based on Edman degradation fragments. Northern blot and in situ hybridization analyses showed that Lma-p54 was expressed in the adult abdominal epidermis and in the chemical sense organs of both sexes. Sequence alignment indicates that Lma-p54 is closely related to aspartic proteases (EC 3.4.23). However, there are critical amino acid substitutions at the level of the active site and, since no proteolytic activity was detected in the abdominal secretion, the protein is likely inactive. As an inactive aspartic protease, Lma-p54 is related to pregnancy-associated glycoproteins (PAGs) which still present a peptide-binding ability. According to recent experiments using whole tergal protein secretions, a role in intraspecific contact recognition was proposed for this surface protein.
