Department of Pediatric General Surgery, Guangdong Women and Children Hospital, Guangzhou, 511442, Guangdong, China.
Hepatocellular carcinoma (HCC) is one of the deadliest types of tumors. MicroRNA (miRNA) MTCO3P38 is a novel miRNA derived from the pseudogene MTCO3P38 with 18 nucleotides in length. The target genes of miR-MTCO3P38 were predicted by Targetscan, RNAhybrid and PITA.

Prenatal exposure to hazardous environmental pollutants is a critical global concern due to their confirmed presence in umbilical cord blood, indicating the ability of pollutants to cross the placental barrier and expose the fetus to harmful compounds. However, the transplacental transfer efficiencies (TTEs) of many pollutants remain underexplored. Herein, we developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to quantitatively analyze 91 environmental pollutants, including 13 bisphenols (BPs), 18 organophosphorus flame retardants (OPFRs), 7 brominated and other flame retardants (BFRs), 34 phthalates (PAEs), and 19 per- and polyfluoroalkyl substances (PFASs), in paired maternal and cord serums.

Hexabromocyclododecane (HBCD) poses significant environmental risks, and identifying HBCD-degrading microbes and their enzymatic mechanisms is challenging due to the complexity of microbial interactions and metabolic pathways. This study aimed to identify critical genes involved in HBCD biodegradation through two approaches: functional annotation of metagenomes and the interpretation of machine learning-based prediction models. Our functional analysis revealed a rich metabolic potential in Chiang Chun soil (CCS) metagenomes, particularly in carbohydrate metabolism.

The brominated flame retardant 2, 2', 4, 4'-tetrabromodiphenyl ether (PBDE-47) is known as a developmental neurotoxicant, yet the underlying mechanisms remain unclear. This study aims to explore its neurotoxic mechanisms by integrating network toxicology with transcriptomics based on human neural precursor cells (hNPCs) and neuron-like PC12 cells. Network toxicology revealed that PBDE-47 crosses the blood-brain barrier more effectively than heavier PBDE congeners, and is associated with disruptions in 159 biological pathways, including cytosolic DNA-sensing pathway, ferroptosis, cellular senescence, and chemokine signaling pathway.

4-Cyano-4'-ethoxybiphenyl (EBCN) is a representative cyano liquid crystal monomer (LCM). While prior studies have documented the widespread occurrence of LCMs in diverse environmental and biological samples, research on their reproductive effects in vivo remains limited. This study employed 35-day and 70-day exposure models in mice to assess the short-term and long-term effects of environmentally relevant concentrations of EBCN on testicular health.
