Summary: The developmental toxicity of 4-octylphenol (OP) as an estrogenic endocrine disruptor was confirmed in frog embryos, leading to inhibition of head cartilage development and melanocyte generation. OP-induced dysplasia may be attributed to deregulation of neural crest cells in embryos.

Summary: This study examined the influence of hMCT9 gene variants L93M and T258K on its transport characteristics. The results showed that L93M slightly decreased the transport activity of creatine, while T258K did not affect it. Interestingly, T258K abolished Na+ sensitivity and altered the substrate affinity.

Summary: This study found that statins can inhibit the transport activities of hMCT1, hMCT2, and hMCT4, with atorvastatin showing potent isoform-selective inhibition of hMCT2. Docking simulation revealed that atorvastatin could interact with a specific site, potentially leading to the discovery of more potent hMCT2-selective inhibitors. These findings are important for understanding the inhibitory mechanism of statins against hMCT1, hMCT2, and hMCT4, and may contribute to the development of novel anticancer agents.

Summary: This protocol is developed for identifying mRNAs that form complexes with mRNA-binding proteins in Xenopus laevis embryos at different developmental stages. It describes the use of the Ybx1 mRBP for immunoprecipitation-based mRNA isolation, featuring the translation of the mRBP of interest directly in living embryos following injection of synthetic mRNA templates encoding a hybrid of this protein with a specific tag.

Summary: The effects of 60% oxygen exposure on the pH of lung cancer cells were evaluated in this study. The results showed that hyperoxia exposure reduced intracellular pH, leading to a decrease in the proliferation, invasion, and epithelial-to-mesenchymal transition of lung cancer cells. MCT1 was found to mediate intracellular lactate accumulation and acidification of the cells under hyperoxic conditions.

Summary: Precise regulation of thyroid hormone (TH) signaling is crucial for coordinating developmental events in frog metamorphosis. This study investigates the role of monocarboxylate transporter 8 (MCT8) in TH transport during metamorphosis. By using CRISPR/Cas9, mutant tadpoles with MCT8 gene mutations were produced and it was found that the loss of MCT8 did not affect TH-dependent development, suggesting compensatory TH transport in tadpole tissues.

Summary: This study investigated the skeletal toxicity of lead acetate (PbAc) in early life stages of zebrafish. The results showed that PbAc inhibited the differentiation and maturation of osteoblasts and cartilage matrix, promoted the formation of osteoclasts, disrupted the GH/IGF-1 axis, and ultimately induced cartilage defects and bone loss in zebrafish embryos.

Summary: This study clarified the effect of 2,2',4,4'-tetrabromodiphenyl ether (BDE47) on depression in mice and explored the role of the microbiome-gut-brain axis. BDE47 exposure increased depression-like behaviors in mice and disrupted dopamine transmission in the brain. It also disrupted microbiota communities in the intestines and caused metabolic disorders and inflammatory signaling. Overall, BDE47-induced depression in mice is likely mediated by gut microbial dysbiosis and disrupted signaling pathways.

Summary: Rhabdomyosarcomas (RMS) are soft tissue sarcomas predominantly found in children, and current treatments have severe side effects and poor outcomes, necessitating the discovery of novel, more targeted therapies. High expression of histone demethylases, particularly KDM4B, supports proliferation of RMS cells, and sustained knockdown of KDM4B can lead to functional compensation by KDM4A. Targeting both KDM4A and KDM4B is shown to be effective in killing RMS cells and overcoming functional redundancy in order to elicit strong therapeutic responses.

Summary: Despite advances in the treatment of oesophageal adenocarcinoma, the overall prognosis remains poor with few patients surviving more than 5 years from diagnosis. Epigenetic targets, specifically histone-modifying enzymes, have been identified as potential novel therapeutic options in OAC. Research on their roles in tumor formation and potential use as targeted therapies is ongoing.

Summary: Esophageal adenocarcinoma (EAC) patients receive pre-operative chemotherapy, but a significant portion do not respond to this treatment, exhibiting chromosomal instability and gene copy number alterations. Different genetic profiles, including mutations in the tumor suppressor NAV3, are associated with non-responders, presenting potential drug targets for alternative treatment pathways.

Summary: Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma in children and adolescents, characterized by aberrant muscle differentiation. Abnormalities in the regulatory transcription factors (MRFs) involved in skeletal muscle development contribute to tumorigenesis in RMS. Core regulatory circuitries (CRCs) and hierarchically organized subsets of cells play a role in maintaining the disease-driving fusion oncogene and promoting malignancy in RMS. Understanding the genetic and epigenetic framework of abnormal muscle differentiation in RMS provides insights into its mechanisms and potential therapeutic strategies.
