Gastric cancer (GC) poses global challenges due to its difficult early diagnosis and drug resistance, necessitating the identification of early detection markers and understanding of oncogenic pathways for effective GC therapy. Endothelial cell-specific molecule 1 (ESM1), a secreted glycoprotein, is elevated in various cancers, but its role in GC remains controversial. In our study, ESM1 was elevated in GC tissues, and its concentration was correlated with progression and poorer patient prognosis in independent cohorts.

Study Question: Does exposure to a mixture of ambient air pollutants during specific exposure periods influence clinical pregnancy rates in women undergoing IVF/ICSI-embryo transfer (ET) cycles?

Summary Answer: The specific exposure period from ET to the serum hCG test was identified as a critical exposure window as exposure to sulfur dioxide (SO) or a combination of air pollutants was associated with a decreased likelihood of clinical pregnancy.

What Is Known Already: Exposure to a single pollutant may impact pregnancy outcomes in women undergoing ART. However, in daily life, individuals often encounter mixed pollution, and limited research exists on the effects of mixed air pollutants and the specific exposure periods.

Revisiting Luteolin Against the Mediators of Human Metastatic Colorectal Carcinoma: A Biomolecular Approach.

J Cell Biochem

January 2025

Integrative Biochemistry and Immunology Laboratory, Department of Animal Science, Kazi Nazrul University, Asansol, West Bengal, India.

Metastatic colorectal carcinoma (mCRC) is one of the prevalent subtypes of human cancers and is caused by the alterations of various lifestyle and diet-associated factors. β-catenin, GSK-3β, PI3K-α, AKT1, and NF-κB p50 are known to be the critical regulators of tumorigenesis and immunopathogenesis of mCRC. Unfortunately, current drugs have limited efficacy, side effects and can lead to chemoresistance.

Food Chem

January 2025

Department of Biomedical Sciences, Chung Shan Medical University, No.110, Sec. 1, Chien Kuo N. Rd, Taichung 402, Taiwan; Department of Medical Research, Chung Shan Medical University Hospital, No.110, Sec. 1, Chien Kuo N. Rd, Taichung 402, Taiwan. Electronic address:

This study presents the first successful generation of polyclonal antibodies (pAbs) and oligonucleotide aptamers specifically targeting fusaric acid (FA). Utilizing these pAbs and aptamers, three highly sensitive and specific assays were developed for the detection of FA in cereals with limits of detection (LOD) ranging from 5 to 50 ng/g: an antibody-based enzyme-linked immunosorbent assay (ELISA), an aptamer-based enzyme-linked aptamer-sorbent assay (ELASA), and a hybrid enzyme-linked aptamer-antibody sandwich assay (ELAAA). The recovery rates of FA in spiked cereal samples ranged from 87 % to 112 % across all assays.

Citrinin disrupts microtubule assembly in cardiac cells: Impact on mitochondrial organization and function.

Chemosphere

October 2024

Graduate Institute of Toxicology, College of Medicine, National Taiwan University, Taipei, Taiwan. Electronic address:

Citrinin (CTN) is a mycotoxin commonly present in various foods and feeds worldwide, as well as dietary supplements in Asian countries, but the risks and cellular mechanisms associated with its cardiotoxicity remains unclear. In this study, RNA-seq analysis of CTN-treated H9c2 cardiac cells demonstrated significant perturbations in pathways related to microtubule cytoskeleton and mitochondrial network organization. CTN disrupted microtubule polymerization and downregulated mRNA levels of microtubule-assembling genes, Map2 and Tpx2, in H9c2 cardiac cells.

Merkel cells and corpuscles of Stannius as putative targets for polyethylene terephthalate microfibers in sheepshead minnow larvae.

October 2024

Environmental Exposure & Toxicology Research Center, Korea Institute of Toxicology, 17 Jegok-gil, Jinju 52834, Republic of Korea; Human and Environmental Toxicology Program, Korea University of Science and Technology (UST), 217, Gajeong-ro, Daejeon 34113, Republic of Korea. Electronic address:

Polyethylene terephthalate (PET) fibers are contaminated in wastewater from various primary sources, such as washing textile waters. PET fibers in the environment can be degraded into microfibers because of weathering processes such as sunlight, physical wear, and heat. Although recent studies reported adverse effects of PET microfibers on aquatic organisms, the lack of information on their toxicity and mode of action hampers the risk assessment of PET microfibers.

  • The activation of human immune cells by intestinal microorganisms, like probiotics and prebiotics, is crucial for maintaining a healthy balance between beneficial and harmful bacteria in the gut.
  • Probiotic products are becoming popular, especially for skin health and managing atopic dermatitis (AD), which is linked to immune system reactions and inflammation.
  • A study on anti-atopic substances showed that treatment reduced symptoms of AD by decreasing skin inflammation and improving immune responses, as observed through various tests on experimental animals.

Current human risk assessments often rely on animal toxicity data to establish point of departure (POD) values, followed by the application of uncertainty factors. Consequently, there is growing interest in alternative toxicity testing methods that reduce reliance on animal models. In this study, we propose a novel approach for inhalation toxicity risk assessment that integrates in silico and in vitro methods.

  • AIMP2-DX2 (DX2) is a variant of a protein linked to cancer, and reducing its levels can help stop tumor growth.
  • Researchers found that a compound called SDL01 enhances the interaction between DX2 and another protein, Siah1, promoting DX2's degradation.
  • SDL01 binds to a specific area on DX2, causing a change in its shape that strengthens its interaction with Siah1, showing that drug-induced changes can alter protein interactions.*

Benzene occurs naturally and is widely applied in the production process of petrochemical products. It is mainly exposed through the respiratory tract and dermal and metabolized in the liver, leading to systemic health effects, and 1,2,4-trihydroxybenzene (THB) is a benzene metabolite used as a hair dye ingredient in some countries. In an effort to identify a toxic mechanism of THB, we first analyzed the hair of consumers who used a shampoo containing THB, and contrary to our expectations, THB was not persistent in the hair.
