Special Issue Information

Dear Colleagues,

It is well known that the intake of fruits, vegetables, and herbs can reduce the risk of developing chronic diseases such as diabetes, obesity, and several cancers. Phytochemicals are considered as active dietary compounds for such effects with tissue-specific activities; however, the molecular targets of the phytochemicals are still not well characterized. A single phytochemical may often exhibit multiple biological activities. In many cases, little attention has been given to the molecular target of a phytochemical, and a single phytochemical sometimes has multiple target proteins. On the other hand, there are not sufficient epidemiologic data to suggest an association between a specific phytochemical and a disease of interest. At the molecular level, moreover, we still need more information regarding biomarkers for such diseases where there is an interaction with phytochemicals.

This Special Issue will collect research results focusing on different aspect of phytochemicals, focusing on novel functions in energy metabolism and cancers. In-depth study of the mechanisms involving signal transduction pathways and regulation of gene expression altered by phytochemicals will be helpful for this field of science. Investigation of new genetic and biochemical biomarkers for obesity, diabetes, dyslipidemia, atherosclerosis, and cancers in relation to phytochemicals will be also of interest for explaining the diverse biological functions of phytochemicals, with sometimes multiple targets in cells. In documenting the latest advances, it is hoped that this issue will contribute to a better understanding in the phytochemical research field.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English.

The process of adipocyte browning has recently emerged as a novel therapeutic target for combating obesity and obesity-related diseases. Non-shivering thermogenesis is the process of biological heat production in mammals and is primarily mediated via brown adipose tissue (BAT). The recruitment and activation of BAT can be induced through chemical drugs and nutrients, with subsequent beneficial health effects through the utilization of carbohydrates and fats to generate heat to maintain body temperature. However, since potent drugs may show adverse side effects, nutritional or natural substances could be safe and effective as potential adipocyte browning agents. This review aims to provide an extensive overview of the natural food compounds that have been shown to activate brown adipocytes in humans, animals, and in cultured cells. In addition, some key genetic and molecular targets and the mechanisms of action of these natural compounds reported to have therapeutic potential to combat obesity are discussed. Full article

The plant-derived α-linolenic acid (ALA) is an essential n-3 acid highly susceptible to oxidation, present in oils of flaxseeds, walnuts, canola, perilla, soy, and chia. After ingestion, it can be incorporated in to body lipid pools (particularly triglycerides and phospholipid membranes), and then endogenously metabolized through desaturation, elongation, and peroxisome oxidation to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), with a very limited efficiency (particularly for DHA), beta-oxidized as an energy source, or directly metabolized to C18-oxilipins. At this moment, data in the literature about the effects of ALA supplementation on metabolic syndrome (MetS) in humans are inconsistent, indicating no effects or some positive effects on all MetS components (abdominal obesity, dyslipidemia, impaired insulin sensitivity and glucoregulation, blood pressure, and liver steatosis). The major effects of ALA on MetS seem to be through its conversion to more potent EPA and DHA, the impact on the n-3/n-6 ratio, and the consecutive effects on the formation of oxylipins and endocannabinoids, inflammation, insulin sensitivity, and insulin secretion, as well as adipocyte and hepatocytes function. It is important to distinguish the direct effects of ALA from the effects of EPA and DHA metabolites. This review summarizes the most recent findings on this topic and discusses the possible mechanisms. Full article
