Abstract
The 2nd Nutrition and Cancer Networking Meeting 'Nutrition and Breast Cancer: Translating Evidence into Practice' was held at Newcastle University in May 2022, with support from the Nutrition Society and British Association for Cancer Research. The first meeting in this series was held in Sheffield in 2019. The aim of this joint meeting was to bring together researchers with an interest in nutrition and breast cancer, with the programme spanning topics from risk and prevention to nutrition during treatment and beyond. Several key themes emerged, including the importance of engaging patients in the development of interventions and trials, making trials more accessible to diverse communities; training of clinical staff in nutrition and latest evidence; wider range of compounds should be considered in food composition tables; and alternative trial designs can be considered for prevention research to reduce financial burden and increase power.

Abstract
Each year, 20 million tons of wine by-products are generated, corresponding to 30% of the total quantity of vinified grapes. Wine by-products are a source of healthy bioactive molecules, such as polyphenols and other molecules (pigments, fibers, minerals, etc.). The abundance of bioactive compounds assures a promising future for nutritional foodstuff production. Wine by-products can be used to fortify aromatized waters and infusions, bread, pasta, dairy products, alcohol, sugary beverages, and processed foods. These innovative products are part of the Mediterranean diet and are of great interest to both human and environmental health. Pre-clinical studies show that consumption of food produced with wine by-products or with their extracts attenuates the inflammatory state and increases antioxidant status. As such, wine by-products provide protective effects against the underlying pathophysiological hallmarks of some chronic diseases such as atherosclerosis, diabetes, hypertension, obesity, and cancer. However, the poor bioavailability warrants further investigation on how to optimize the efficacy of wine by-products, and more clinical trials are also needed. The scientific evidence has validated the uses of the dietary nature of wine by-products and has helped to promote their use as a functional food to prevent chronic human diseases.

Abstract
Wine production is one of the most critical agro-industrial sectors worldwide, generating large amounts of waste with negative environmental impacts, but also with high economic value and several potential applications. From wine shoots to grape pomace or seeds, all of the wastes are rich sources of bioactive compounds with beneficial effects for human health, with these compounds being raw materials for other industries such as the pharmaceutical, cosmetic or food industries. Furthermore, these compounds present health benefits such as being antioxidants, supporting the immune system, anti-tumoral, or preventing cardiovascular and neural diseases. The present work aims to be a critical discussion of the extraction methods used for bioactive compounds from grapevine waste and their beneficial effects on human health.

[PMID: 35331093 DOI: 10.2174/1389557522666220324123605] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 01/02/2022] [Accepted: 01/21/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Pancreatic cancer is a fatal malignant neoplasm with infrequent signs and symptoms until a progressive stage. In 2020, GLOBOCAN reported that pancreatic cancer accounts for 4.7% of all cancer deaths. Despite the availability of standard chemotherapy regimens for treatment, the survival benefits are not guaranteed because tumor cells become chemoresistant even due to the development of chemoresistance in tumor cells even with a short treatment course, where apoptosis and autophagy play critical roles. OBJECTIVE This review compiled essential information on the regulatory mechanisms and roles of apoptosis and autophagy in pancreatic cancer, as well as drug-like molecules that target different pathways in pancreatic cancer eradication, with an aim to provide ideas to the scientific communities in discovering novel and specific drugs to treat pancreatic cancer, specifically PDAC. METHOD Electronic databases that were searched for research articles for this review were Scopus, Science Direct, PubMed, Springer Link, and Google Scholar. The published studies were identified and retrieved using selected keywords. DISCUSSION/CONCLUSION Many small-molecule anticancer agents have been developed to regulate autophagy and apoptosis associated with pancreatic cancer treatment, where most of them target apoptosis directly through EGFR/Ras/Raf/MAPK and PI3K/Akt/mTOR pathways. The cancer drugs that regulate autophagy in treating cancer can be categorized into three groups: i) direct autophagy inducers (e.g., rapamycin), ii) indirect autophagy inducers (e.g., resveratrol), and iii) autophagy inhibitors. Resveratrol persuades both apoptosis and autophagy with a cytoprotective effect, while autophagy inhibitors (e.g., 3-methyladenine, chloroquine) can turn off the protective autophagic effect for therapeutic benefits. Several studies showed that autophagy inhibition resulted in a synergistic effect with chemotherapy (e.g., a combination of metformin with gemcitabine/ 5FU). Such drugs possess a unique clinical value in treating pancreatic cancer as well as other autophagy-dependent carcinomas.

Abstract
Eicosanoids and other oxylipins play an important role in mediating inflammation as well as other biological processes. For the investigation of their biological role(s), comprehensive analytical methods are necessary, which are able to provide reliable identification and quantification of these compounds in biological matrices. Using charge-switch derivatization with AMPP (N-(4-aminomethylphenyl)pyridinium chloride) in combination with liquid chromatography ion mobility quadrupole time-of-flight mass spectrometry (LC-IM-QTOF-MS), we developed a non-target approach to analyze oxylipins in plasma, serum, and cells. The developed workflow makes use of an ion mobility resolved fragmentation to pinpoint derivatized molecules based on the cleavage of AMPP, which yields two specific fragment ions. This allows a reliable identification of known and unknown eicosanoids and other oxylipins. We characterized the workflow using 52 different oxylipins and investigated their fragmentation patterns and ion mobilities. Limits of detection ranged between 0.2 and 10.0 nM (1.0-50 pg on column), which is comparable with other state-of-the-art methods using LC triple quadrupole (QqQ) MS. Moreover, we applied this strategy to analyze oxylipins in different biologically relevant matrices, as cultured cells, human plasma, and serum. Graphical abstract.

Abstract
Background Resveratrol, a natural polyphenolic phytoalexin, has potent anti-tumor activity. Recently, it was found to induce autophagy in cancer cells. However, the effects of resveratrol on autophagy in non-small-cell lung cancer (NSCLC) cells have not yet been clearly elucidated. Materials and methods A549 and H1299 cells were treated with different concentrations of resveratrol. Cell growth and apoptosis were measured by CCK-8 assay and flow cytometry, respectively. A549 cells were then treated with 200 μM resveratrol or SRT1720. Cell autophagy was detected by western blot and immunofluorescence. Results In this study, we found that resveratrol exerted the anti-tumor effect through inhibiting cell proliferation and promoting cell apoptosis in NSCLC cells dose-dependently. Resveratrol has also increased the relative expression of Beclin1 and LC3 II/I while decreased p62 expression, suggesting that resveratrol induced autophagy in NSCLC cells. In addition, resveratrol increased SIRT1 expression and SIRT1 activator SRT1720-induced autophagy of NSCLC cells. SIRT1 knockdown reduced resveratrol-induced autophagy significantly. These results indicated that resveratrol might induce autophagy through upregulating SIRT1 expression. Moreover, inhibiting autophagy by autophagy inhibitor 3-methyladenine or SIRT1 inhibitor nicotinamide significantly suppressed proliferation while promoted apoptosis compared with the resveratrol 200 μM group, suggesting that resveratrol-induced autophagy might act as a protective mechanism to promote NSCLC cell survival and inhibiting autophagy can enhance the anti-tumor effect of resveratrol. Besides that, resveratrol treatment inhibited Akt/mTOR while p38-MAPK was activated in NSCLC cells in a dose-dependent manner. Activating Akt/ mTOR pathway by IGF-1 or inhibiting p-38-MAPK pathway by doramapimod significantly inhibited cell proliferation while increased cell apoptosis of NSCLC cells compared with the resveratrol 200 μM group. Conclusion Taken together, our findings suggest that resveratrol inhibited proliferation but induced apoptosis and autophagy via inhibiting Akt/mTOR and activating p38-MAPK pathway. Resveratrol-induced autophagy might act as a protective mechanism to promote NSCLC cell survival. Therefore, inhibition of autophagy may enhance the anti-tumor activity of resveratrol in NSCLC.
