Fumonisins alone or mixed with other fusariotoxins increase the C22-24:C16 sphingolipid ratios in chicken livers, while deoxynivalenol and zearalenone have no effect
In conclusion the C22-24:C16 ratio emerged as a specific biomarker, with variations dependent only on the presence of fumonisins.PMID:38615975 | DOI:10.1016/j.cbi.2024.111005 (Source: Chemico-Biological Interactions)

Binding Profiles of Human and Mouse Complement Component 8 γ to Trisubstituted Organometallic Compounds
Chem Biol Interact. 2024 Apr 11:110998. doi: 10.1016/j.cbi.2024.110998. Online ahead of print.ABSTRACTComplement component 8gamma (C8γ), a member of the lipocalin protein family, is suggested to act as a carrier protein for various chemicals. Although C8γ has been identified in both humans and rodents for some time, our understanding of the species differences in its chemical binding properties remains limited. In the present study, with the aim to elucidate the potential role of C8γ as a carrier protein in both humans and mice, we conducted a radioligand binding assay to examine the chemical binding properties of human...

The E-liquid Flavoring Vanillin Alters Energy and Autophagic Pathways in Human Proximal Tubule (HK-2) Epithelial Cells
In this study, acute exposure to the popular flavoring vanillin (VAN) was performed on human proximal tubule (HK-2) kidney cells. Cells were exposed to 0-1000 μM VAN for 24 or 48 h and cellular stress responses were determined. Mitochondrial viability using MTT assay showed a significant decrease between the control and 1000 μM group by 48 h. Seahorse XFp analysis showed significantly increased basal respiration, ATP production, and proton leak after 24 h exposure. By 48 h exposure, these parameters remained significantly increased in addition to non-mitochondrial respiration and maximal respiration. Glycolytic activity ...

Bruceantinol works as a CDK2/4/6 inhibitor to inhibit the growth of breast cancer cells
Chem Biol Interact. 2024 Apr 10:110999. doi: 10.1016/j.cbi.2024.110999. Online ahead of print.ABSTRACTBruceantinol (BOL), isolated from the dried fruit of the Brucea javanica (L.) Merr., exhibits cytotoxic effects on breast cancer cells. However, the underlying mechanism remains to be fully addressed. In this paper, the MCF-7 and MDA-MB-231 human breast cancer cell lines were used as experimental models to uncover how BOL inhibits breast cancer cell growth. The effects of BOL on cell growth, proliferation, the cell cycle, and apoptosis were investigated using the MTT assays, EdU incorporation assays, and flow cytometry, re...

Biochemical, structural, and computational analyses of two new clinically identified missense mutations of ALDH7A1
We report a biochemical, structural, and computational study of two novel ALDH7A1 missense mutations that were identified in a child with rare recurrent seizures from the third month of life. The mutations affect two residues in the oligomer interfaces of ALDH7A1, Arg134 and Arg441 (Arg162 and Arg469 in the HGVS nomenclature). The corresponding enzyme variants R134S and R441C (p.Arg162Ser and p.Arg469Cys in the HGVS nomenclature) were expressed in Escherichia coli and purified. R134S and R441C have 10,000- and 50-fold lower catalytic efficiency than wild-type ALDH7A1, respectively. Sedimentation velocity analytical ultrace...

Accumulated LPS induced by colitis altered the activities of vitamin D-metabolizing hydroxylases and decreased the generation of 25-hydroxyvitamin D
Chem Biol Interact. 2024 Apr 6:110997. doi: 10.1016/j.cbi.2024.110997. Online ahead of print.ABSTRACTIt is generally accepted that low vitamin D (VD) levels are associated with a high prevalence factor for Inflammatory bowel disease(IBD). IBD patients have observed higher levels of lipopolysaccharide(LPS), ALT, and AST than healthy people. Gut-derived LPS causes inflammatory injury in the liver and kidney. The VD-metabolizing mechanism is involved in the liver and kidney, which means IBD might impact VD metabolism. However, whether IBD affects VD metabolism has not been studied. In vitro LPS resulted in decreased CYP2R1 in...
