as Potential Co-adjuvant in Pancreatic Cancer: The Energetic Catastrophe Induced via BMP8B Ends Up With Autophagy-Induced Cell Death.

The recent development of powerful "omics" technologies (genomics, transcriptomics, proteomics, metabolomics, and lipidomics) has opened new avenues in nutritional sciences toward precision nutrition, which is a genotype-directed nutrition that takes into account the differential responses to nutritional interventions based on gene variation (nutrigenetics) and the effect of nutrients on gene expression (nutrigenomics). Current evidence demonstrates that up to one third of the deaths caused by cancer could be prevented by acting on key risk factors, with diet being one of the most important risk factors due to its association with obesity. Additional factors such as composition of gut microbiome, the immune system, and the nutritional status will have an impact on the final outcome.

Yarrow Supercritical Extract Ameliorates the Metabolic Stress in a Model of Obesity Induced by High-Fat Diet.

Nowadays, obesity and its associated metabolic disorders, including diabetes, metabolic syndrome, cardiovascular disease, or cancer, continue to be a health epidemic in westernized societies, and there is an increased necessity to explore anti-obesity therapies including pharmaceutical and nutraceutical compounds. Considerable attention has been placed on the identification of bioactive compounds from natural sources to manage the metabolic stress associated with obesity. In a previous work, we have demonstrated that a CO supercritical fluid extract from yarrow (Yarrow SFE), downregulates the expression of the lipogenic master regulator and its downstream molecular targets and in a tumoral context.

Yarrow supercritical extract exerts antitumoral properties by targeting lipid metabolism in pancreatic cancer.

Metabolic reprogramming is considered a hallmark of cancer. Currently, the altered lipid metabolism in cancer is a topic of interest due to the prominent role of lipids regulating the progression of various types of tumors. Lipids and lipid-derived molecules have been shown to activate growth regulatory pathways and to promote malignancy in pancreatic cancer.

Lipidomics Insights in Health and Nutritional Intervention Studies.

Lipids are among the major components of food and constitute the principal structural biomolecules of human body together with proteins and carbohydrates. Lipidomics encompasses the investigation of the lipidome, defined as the entire spectrum of lipids in a biological system at a given time. Among metabolomics technologies, lipidomics has evolved due to the relevance of lipids in nutrition and their well-recognized roles in health.

Improving Efficacy of Bioactive Molecules: An Overview of Potentially Antitumor Phytochemicals and Currently Available Lipid-Based Delivery Systems.

Cancer is among the leading causes of morbidity and mortality worldwide. Many of the chemotherapeutic agents used in cancer treatment exhibit cell toxicity and display teratogenic effect on nontumor cells. Therefore, the search for alternative compounds which are effective against tumor cells but reduce toxicity against nontumor ones is of great importance in the progress or development of cancer treatments.

Biological Activities of Asteraceae (Achillea millefolium and Calendula officinalis) and Lamiaceae (Melissa officinalis and Origanum majorana) Plant Extracts.

Asteraceae (Achillea millefolium and Calendula officinalis) and Lamiaceae (Melissa officinalis and Origanum majorana) extracts were obtained by applying two sequential extraction processes: supercritical fluid extraction with carbon dioxide, followed by ultrasonic assisted extraction using green solvents (ethanol and ethanol:water 50:50). The extracts were analyzed in terms of the total content of phenolic compounds and the content of flavonoids; the volatile oil composition of supercritical extracts was analyzed by gas chromatography and the antioxidant capacity and cell toxicity was determined. Lamiaceae plant extracts presented higher content of phenolics (and flavonoids) than Asteraceae extracts.

CALHM1 and its polymorphism P86L differentially control Ca²⁺homeostasis, mitogen-activated protein kinase signaling, and cell vulnerability upon exposure to amyloid β.

The mutated form of the Ca²⁺channel CALHM1 (Ca²⁺homeostasis modulator 1), P86L-CALHM1, has been correlated with early onset of Alzheimer's disease (AD). P86L-CALHM1 increases production of amyloid beta (Aβ) upon extracellular Ca²⁺removal and its subsequent addback. The aim of this study was to investigate the effect of the overexpression of CALHM1 and P86L-CALHM, upon Aβ treatment, on the following: (i) the intracellular Ca²⁺signal pathway; (ii) cell survival proteins ERK1/2 and Ca²⁺/cAMP response element binding (CREB); and (iii) cell vulnerability after treatment with Aβ.
