Ascorbic Acid and Graphene Oxide Exposure in the Model Organism Can Change the Reproduction Potential.

The use of nanoparticles in the industry carries the risk of their release into the environment. Based on the presumption that the primary graphene oxide (GO) toxicity mechanism is reactive oxygen species production in the cell, the question arises as to whether well-known antioxidants can protect the cell or significantly reduce the effects of GO. This study focused on the possible remedial effect of vitamin C in intoxicated with GO for whole lives.

New reports on iron related proteins: Molecular characterization of two ferroportin genes in common carp (Cyprinus carpio L.) and its expression pattern.

Iron uptake, transport, and storage require the involvement of several proteins, including ferroportin (fpn), the sole known iron efflux transporter. Due to its critical function fpn has been studied, particularly in humans. Here, we characterized the ferroportin gene in common carp (Cyprinus carpio L.

Roundup in the Reproduction of Crucian Carp (): An In Vitro Effect on the Pituitary Gland and Ovary.

Roundup, the most popular herbicide in global agriculture, is regarded as an endocrine disruptor causing alterations of important hormones at the hypothalamic-pituitary-gonadal axis as well as impairment of gametogenesis. The whole pituitary glands of crucian carp () were incubated for 3 h in the medium containing Roundup (0-control, 1 and 10 ng/mL). The level of luteinizing hormone (LH), and mRNA transcript abundance of kisspeptin () and its receptor (), were determined.

Re-evaluation of common carp (Cyprinus carpio L.) housekeeping genes for gene expression studies - considering duplicated genes.

Quantitative real-time PCR is one of the most widely used techniques for measuring changes in the expression of target transcripts due to its sensitivity, specificity, and cost-effectiveness. However, the essential step that determines appropriate and correct data interpretation is the selection of proper endogenous control genes. Identifying useful reference genes with stable expression is critical for accurate normalization and precise results.

The many faces of transferrin: Does genotype modulate immune response?

In this study, the expression of pro-inflammatory and iron metabolism genes were analysed under Trypanoplasma borreli (T. borreli) challenge in common carp. Three transferrin (Tf) genotypic groups: two homozygous - DD, GG, and heterozygous DG were intraperitoneally infected with a dose of 2.

Anti-CyHV-3 Effect of Fluorescent, Tricyclic Derivative of Acyclovir 6-(4-MeOPh)-TACV .

Introduction: (CyHV-3) is a virus infecting carp with disease symptoms of gill necrosis, fish discoloration, sunken eyes, and mortality reaching 90%. Several research groups have examined how to potentially abate the consequences of viral activity. Recently we showed that acyclovir inhibits CyHV-3 replication and in the present study we examined the anti-CyHV-3 activity of the tricyclic derivative of acyclovir 6-(4-MeOPh)-TACV (T-ACV), a fluorescent molecule known for higher lipophilicity than acyclovir, and therefore potentially better candidate for application .

Influence of the Genetic Makeup of Common Carp on the Expression of Iron-related Genes During Infection.

Introduction: Genes related to iron metabolism play an important role in inflammatory response. The objective of this study was to investigate the role of ferritin, transferrin receptors 1a and 1b, and transferrin genes in the response to blood parasite infection in common carp ( L.).

Acyclovir inhibits Cyprinid herpesvirus 3 multiplication in vitro.

Cyprinid herpesvirus 3 (CyHV-3), also known as koi herpesvirus (KHV), is an aetiological agent of a virulent and lethal disease in common and koi carp. In this study, we examined in vitro the anti-CyHV-3 activity of acyclovir (ACV), nucleoside analogue commonly used against human herpesviruses, as well as acyclovir monophospate (ACV-MP). The cytotoxicity of the ACV and the ACV-MP for two common carp cell lines, CCB (Common carp brain) and KF1 (Koi carp fin 1), was determined by means of MTT and crystal violet assays.

Hematological Alterations as a Response to Exposure to Selected Fungicides in Common Carp (Cyprinus carpio L.).

The aim of the present study was to assess the hematological response of common carp to fungicides and to determine recovery patterns in fungicide-free water. Fish were exposed to mancozeb, prochloraz or tebuconazole (at concentrations of 1.0, 1.

The localisation of HSP70 and oxidative stress indices in heads of Spodoptera exigua larvae in a cadmium-exposed population.

The effects of cadmium toxicity may vary between animals with different history of metal exposure. The aim of our study was to examine HSP70, protein carbonyl levels, catalase activity and total antioxidant capacity in the heads of Spodoptera exigua (Hübner) larvae originated from undergoing 1- and 44-generational cadmium treatment and in control (those that were not exposed to cadmium). We also measured the cadmium concentration and DNA damage level in the larvae.
