Thymol exposure mediates pro-oxidant shift by regulating Nrf2 and apoptotic events in zebrafish (Danio rerio) embryos
In this study, we exposed the zebrafish embryos to 25, 50 and 100µM of THY for 96 hours post fertilization (hpf). Noticeable teratogenic effects were observed upon assessing the survival rate (LC50 = 42.35µM), hatching process, morphological exam and cardiac functions, thereby verifying the toxicity of THY on zebrafish embryos. Furthermore, we analyzed the effect of THY on the levels of ROS, mitochondrial membrane potential (ΔΨm) and immunofluorescence by DCFH-DA, JC-1, Casp-3-FITIC staining, respectively.

Phthalates Promote Prostate Cancer Cell Proliferation through Activation of ERK5 and p38
In this report we found that three typical phthalates, diethylhexyl phthalate (DEHP), Butyl benzyl phthalate (BBP) and Dibutyl phthalate (DBP), up-regulated cyclinD1 and PCNA, down-regulated P21, inducing proliferation of prostate cancer cells. Furthermore, we found that phthalates increased the expression of p-ERK5 and p-p38, along with upregulation of AP-1 (p-c-fos and p-c-jun). In studies with ERK5 and a p38 inhibitor, our data showed that downregulation of p-ERK5 or p38 inhibited phthalate-triggered cell proliferation.

Effects and mechanisms of sub-chronic exposure to Copper nanoparticles on renal cytochrome P450 enzymes in rats
In this study, we investigated the effects of Cu NPs on renal oxidative stress, cytokines and histopathology of rats. We found that Cu NPs (200 mg/kg) significantly disordered the function and structure of the kidney and caused a dose-dependent increase in oxidative stress and cytokines, which significantly decreased the levels of mRNA, protein, and activity of CYP450 s. Micro-coppers (Cu MPs) and Cu ions have similar effects, but their effects on CYP450 s were weaker than Cu NPs. The expression of nuclear receptors were inhibited and the expression of Akt, STAT3/5, CREB, p70S6K, NF-κB, P38 and E...

4-tert-octylphenol injures motility and viability of human sperm by affecting cAMP-PKA/PKC-tyrosine phosphorylation signals
Publication date: Available online 3 August 2018Source: Environmental Toxicology and PharmacologyAuthor(s): Shaoping Huang, Senyang Cao, Tao Zhou, Lu Kong, Geyu LiangABSTRACT4-tert-octylphenol (4t-OP) is a well-known xenoestrogen. Our objective was to explore the effects and molecular mechanisms of 4t-OP on human sperm. Sperm samples were exposed to 0, 0.1, or 0.3 mM 4t-OP for two hours. Results showed that both sperm viability and motility were significantly injured by 0.3 mM 4t-OP. We applied comparative proteomics to explore the molecular targets affected by 4t-OP. 81 differentially expressed (DE) proteins...

MicroRNA -375 inhibits the proliferation, migration and invasion of kidney cancer cells by triggering apoptosis and modulation of PDK1 expression
In this study we investigated the potential of miR-375 as the therapeutic target for the treatment of Kidney cancer. The results revealed that miR-375 is significantly downregulated in the Kidney cancer cells. To investigate the role therapeutic potential of miR-375, one kidney cancer cell line (A-498) was selected for further experimentation. It was observed that overexpression of miR-375 inhibits A-498 kidney cancer proliferation by induction of apoptosis. In addition, overexpression of miR-375 causes suppression of migration and invasion of the A-498 kidney cancers cells. Bioinformatic analysis revealed PDK1 to be putat...

The effects of 1st and 2nd generation biodiesel exhaust exposure on hematological and biochemical blood indices of Fisher344 male rats – the FuelHealth project
In conclusion, exposure to DEE from B7, which was associated with higher exposure to polycyclic aromatic hydrocarbons, resulted in decreased number of T and NK lymphocytes, while DEE from SHB20 induced a higher level of DNA single-strand breaks, oxidative stress and increased red blood cells parameters. Additionally, DPF technology generated increased number of smaller PM and made the DEE more reactive and more harmful, manifested as deregulation of redox balance.
