Understanding Solvent/Bixin Interactions by Raman Spectroscopy

Journal of the Brazilian Chemical Society, 2020
In this work, Raman spectroscopy and density functional theory (DFT) calculations have been used in order to understand the nature of the interaction between the carotenoid bixin and organic solvents with dielectric constant varying from ca. 2 (toluene) to ca. 47 (dimethyl sulfoxide). Raman shifts registered for the main carotenoid marker band, the C=C

Microlasers Made Entirely from Edible Substances

Advanced Optical Materials, Volume 13, Issue 22, August 5, 2025.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

Carotenoids Modulate FoxO‐Induced Cell Cycle Arrest in Human Cancer Cell Lines: A Scoping Review

Food Science &Nutrition, Volume 13, Issue 4, April 2025.
Carotenoids upregulated pro‐apoptotic and FoxO signalling clusters. Carotenoids downregulated PI3k/Akt signalling, TNF signalling and cell cycle regulation clusters. Carotenoids may induce cell cycle arrest via the FoxO signalling pathway. ABSTRACT Carotenoids, a class of antioxidants, have shown great potential for cancer management.

Gaudichaudione H Enhances the Sensitivity of Hepatocellular Carcinoma Cells to Disulfidptosis via Regulating NRF2‐SLC7A11 Signaling Pathway

Advanced Science, Volume 12, Issue 11, March 20, 2025.
Gaudichaudione H (GH) effectively activates NRF2 signaling and its target genes, such as SLC7A11, and pharmaceutical activation of NRF2‐SLC7A11 signaling pathway aggravates uptake of cysteine, disturbance of GSH synthesis, depletion of NADPH, and accumulation of disulfide molecules, ultimately leading to the formation of disulfide bonds between ...

The role of NRF2 transcription factor in inflammatory skin diseases

BioFactors, Volume 51, Issue 2, March/April 2025.
Nrf2 is essential for maintaining skin homeostasis and regulating inflammation. This review highlights the multifaceted role of Nrf2 in skin inflammatory diseases like atopic dermatitis and psoriasis. While Nrf2 activation can be therapeutic, excessive activation can paradoxically exacerbate skin conditions.
