ATP-binding cassette transporter subfamily G member 2 (ABCG2) is responsible for the excretion of foreign substances, such as uric acid (UA) and indoxyl sulfate (IS), from the body. Given the importance of increased ABCG2 expression in UA excretion, we investigated the enhancement of intestinal ABCG2 expression using Lactiplantibacillus plantarum 06CC2 (LP06CC2). Mice were reared on a potassium oxonate-induced high-purine model at doses of 0.02% or 0.1% LP06CC2 for three weeks. Results showed that LP06CC2 feeding resulted in increased ABCG2 expression in the small intestine. The expression level of large intestinal ABCG2 also showed a tendency to increase, suggesting upregulation of the intestinal excretion transporter ABCG2 by LP06CC2. Overall, LP06CC2 treatment increased fecal UA excretion and showed a trend towards increased fecal excretion of IS, suggesting that LP06CC2 treatment enhanced the expression of intestinal ABCG2, thereby promoting the excretion of UA and other substances from the intestinal tract.

In this study, we evaluated the cancer cell killing activity of koji mold-derived extracts using several solvents. The koji mold lipid extract (KML) exhibited potent cytotoxicity against a human leukemia cell line. Fractionation of the KML via silica gel chromatography revealed the presence of active components in fraction (Fr.) 6. Cytotoxic effects of Fr. 6 were inhibited by the ferroptosis inhibitors, ferrostatin-1 and SRS11-92, and the iron chelator, deferoxamine. Interestingly, ferroptosis inhibitors failed to prevent the KML-induced cell death. Fr. 6 decreased the expression of glutathione peroxidase 4 (GPx4) and increased the level of peroxidized plasma membrane lipids. Furthermore, Fr. 6 decreased the intracellular glutathione levels. Overall, our results suggest that Fr. 6 included in KML induces ferroptosis in HL-60 cells.

β-Cryptoxanthin is a type of carotenoid that contributes to the maintenance and improvement of human health. However, it is sensitive to heat during cooking and food processing. Furthermore, like other carotenoids, β-cryptoxanthin is also highly hydrophobic and does not readily solubilize in the gastrointestinal tract. This property results in its low bioaccessibility, and considerable knowledge has been accumulated on improving the bioavailability of β-cryptoxanthin. In this study, we evaluated the effects of different processing methods on the residual amount of β-cryptoxanthin in kumquats. The results showed that preparation of kumquat paste contained more β-cryptoxanthin than its puree. Next, when the paste was mixed with fermented <i>Aspergillus oryzae</i> milk, the β-cryptoxanthin content did not change. A pasteurization study of the kumquat paste mixed with the fermented milk showed that β-cryptoxanthin was more stable at 65 °C than at 85 °C. In addition, to improve the bioaccessibility of β-cryptoxanthin, a mixture of the fermented milk and kumquat-derived β-cryptoxanthin was evaluated using a human intestinal epithelial Caco-2 cell model. The results showed that β-cryptoxanthin in the mixture permeated the membrane 14 times more than β-cryptoxanthin alone.

The anti-cancer effects of various fatty acids are drawing a lot of attention. To determine whether different fatty acids affect the hypoxic response of liver cancer cells, we examined the effects of various fatty acids on the stabilization of the hypoxia-inducible factor (HIF)-1α protein in the HepG2 human hepatocellular carcinoma (HCC) cell line under condition containing 1% O 2 . Of the fatty acids examined, only 9cis, 11trans (c9, t11)-conjugated linoleic acid (CLA) and 10trans, 12cis (t10, c12)-CLA inhibited hypoxia-induced HIF-1α stabilization. In addition, HIF-1α prolyl hydroxylase or proteasome inhibition abrogated the effects of c9, t11- and t10, c12-CLA. Moreover, c9, t11- and t10, c12-CLA significantly inhibited cell proliferation and induced apoptotic cell death under hypoxia. This is the first study showing that c9, t11- and t10, c12-CLA inhibit the hypoxic response in HCC cells. ©2012 by Japan Oil Chemists' Society.
