Exposure to 7,12-dimethylbenz[a]anthracene impacts ovarian DNA damage sensing and repair proteins differently in lean and obese female mice and weight loss may mitigate obesity-induced ovarian dysfunction
Toxicol Appl Pharmacol. 2024 Apr 14:116930. doi: 10.1016/j.taap.2024.116930. Online ahead of print.ABSTRACTObesity impairs oocyte quality, fertility, pregnancy maintenance, and is associated with offspring birth defects. The model ovotoxicant, 7,12-dimethylbenz[a]anthracene (DMBA), causes ovarian DNA damage and follicle loss. Both DMBA-induced chemical biotransformation and the DNA damage response are partially attenuated in obese relative to lean female mice but whether weight loss could improve the DNA damage response to DMBA exposure has not been explored. Thus, at six weeks of age, C57BL/6 J female mice were divided in...

Roxithromycin exposure induces motoneuron malformation and behavioral deficits of zebrafish by interfering with the differentiation of motor neuron progenitor cells
In this study, we used the zebrafish as a vertebrate model to explore the potential developmental toxicity of early ROX exposure, particularly focusing on its effects on locomotor functionality and CaP motoneuron development. Early exposure to ROX induces marked developmental toxicity in zebrafish embryos, significantly reducing hatching rates (n=100), body lengths (n=100), and increased malformation rates (n=100). The zebrafish embryos treated with a corresponding volume of DMSO (0.1%, v/v) served as vehicle controls (veh). Moreover, ROX exposure adversely affected the locomotive capacity of zebrafish embryos, and observa...

Aflatoxin B1 inhibited the development of primary myoblasts of grass carp (Ctenopharyngodon idella) by degrading extracellular matrix
Ecotoxicol Environ Saf. 2024 Apr 15;276:116332. doi: 10.1016/j.ecoenv.2024.116332. Online ahead of print.ABSTRACTAccording to the International Agency for Research on Cancer (IARC), aflatoxin B1 (AFB1) has been recognized as a major contaminant in food and animal feed and which is a common mycotoxin with high toxicity. Previous research has found that AFB1 inhibited zebrafish muscle development. However, the potential mechanism of AFB1 on fish muscle development is unknown, so it is necessary to conduct further investigation. In the present research, the primary myoblast of grass carp was used as a model, we treated myobla...

Effects of Streptomyces sp. HU2014 inoculation on wheat growth and rhizosphere microbial diversity under hexavalent chromium stress
Ecotoxicol Environ Saf. 2024 Apr 15;276:116313. doi: 10.1016/j.ecoenv.2024.116313. Online ahead of print.ABSTRACTWheat (Triticum aestivum L.) is a major foodstuff for over 40% of the world's population. However, hexavalent chromium [Cr(VI)] in contaminated soil significantly affects wheat production and its ecological environment. Streptomyces sp. HU2014 was first used to investigate the effects of Cr (VI) stress on wheat growth. We analyzed the Cr(VI) concentration, physicochemical properties of wheat and soil, total Cr content, and microbial community structures during their interactions. HU2014 reduced the toxicity of C...

Arch Toxicol. 2024 Apr 16. doi: 10.1007/s00204-024-03739-w. Online ahead of print.ABSTRACTAll areas of the modern society are affected by fluorine chemistry. In particular, fluorine plays an important role in medical, pharmaceutical and agrochemical sciences. Amongst various fluoro-organic compounds, trifluoromethyl (CF3) group is valuable in applications such as pharmaceuticals, agrochemicals and industrial chemicals. In the present study, following the strict OECD modelling principles, a quantitative structure-toxicity relationship (QSTR) modelling for the rat acute oral toxicity of trifluoromethyl compounds (TFMs) was e...

Uremic toxins and the brain in chronic kidney disease
J Nephrol. 2024 Apr 16. doi: 10.1007/s40620-024-01929-4. Online ahead of print.ABSTRACTChronic kidney disease (CKD) patients have an increased risk for cognitive impairment compared to the general population. The risk is much higher in CKD patients who progress to end-stage kidney disease (ESKD) and require hemodialysis or peritoneal dialysis. Multiple factors may contribute to cognitive impairment in CKD patients and in patients on chronic dialysis. However, the observation that, after kidney transplantation, there is an improvement in several cognitive performance markers and that some structural and functional brain abn...

Oncological Rehabilitation for Breast Cancer
Rehabilitation (Stuttg). 2024 Apr;63(2):119-130. doi: 10.1055/a-2129-9279. Epub 2024 Apr 16.ABSTRACTAs a result of increasingly individualized and multimodal therapy, prognosis of breast cancer has improved significantly over the last years. However, multimodal treatment and the use of new medications can lead to a variety of somatic, sometimes new, side effects such as fatigue, polyneuropathy or autoimmune toxicities. This and the oncological diagnosis lead to a high level of psychological distress in the women affected and often to subsequent psychological disorders (sleep/anxiety disorders, depression, ...). Both the di...

Abscisic acid signaling through LANCL2 and PPAR γ induces activation of p38MAPK resulting in dormancy of prostate cancer metastatic cells
Oncol Rep. 2024 Mar;51(3):39. doi: 10.3892/or.2024.8698. Epub 2024 Jan 12.ABSTRACTProstate cancer (PCa) is one the most common malignancies in men. The high incidence of bone metastasis years after primary therapy suggests that disseminated tumor cells must become dormant, but maintain their ability to proliferate in the bone marrow. Abscisic acid (ABA) is a stress response molecule best known for its regulation of seed germination, stomal opening, root shoot growth and other stress responses in plants. ABA is also synthesized by mammalian cells and has been linked to human disease. The aim of the present study was to exam...

Deciphering the prognostic landscape of osteosarcoma: Integrating the roles of hippo pathway genes, programmed cell death, and the tumor immune microenvironment
Environ Toxicol. 2024 Apr 15. doi: 10.1002/tox.24280. Online ahead of print.ABSTRACTOsteosarcoma is a highly aggressive cancer prevalent among adolescents and young adults, notorious for its tendency to metastasize to the lungs. This research delves into the molecular foundations of osteosarcoma by examining the role of the Hippo signaling pathway and its interaction with the tumor immune microenvironment (TME). Through analysis of transcriptomic data from the TARGET-OS dataset and control samples from GTEx, we identified a set of 131 genes that link high expression profiles in osteosarcoma with the Hippo pathway. A focuse...
