Special Issue Information

Dear Colleagues,

Dietary supplements include vitamins, minerals, amino acids, whey protein, creatine, and more. Dietary supplements and herbal medicines are very popular in many countries now. Although most people believe that dietary supplements can help us become more healthy, serious toxicities do occur due to the consumption of too many supplements. Some supplements can also cause problems if taken with certain medicines. For example, vitamins C and E may reduce the effectiveness of some chemotherapy drugs.

Complementary medicine is frequently integrated with conventional medicine. Prescription medicines are thoroughly tested before receiving regulatory approval, but despite this, real-world experience reveals undetectable adverse events in clinical trials. Complementary and alternative medicine are considered non-toxic by consumers. However, many of them might produce adverse reactions or interact with prescription medicine.

This Special Issue aims to report all the adverse effects of dietary supplements. We welcome the discussion of adverse events for commonly used supplements such as vitamins, minerals, plant extracts, and so on. We will also look into the protective or harmful effects of complementary and alternative use.

Importantly, the exact active ingredients of the natural origin extracts must be reported in submitted research manuscripts.

Manuscript Submission Information

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. Current Issues in Molecular Biology is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs).

Obesity is one of the major risk factors for metabolic diseases worldwide. This study examined the effects of YC-1102, an extract derived from the roots of Rosa multiflora, on 3T3-L1 preadipocytes and high-fat diet (HFD)-induced obese mice. In vivo experiments involved the oral administration of YC-1102 (100, 150, and 200 mg/kg body weight) daily to mice for eight weeks. YC-1102 was found to downregulate the expressions of PPARγ and C/EBPα during adipogenesis, inhibiting adipocyte differentiation and upregulating the expression of PGC-1α for energy metabolism to enhance mitochondrial biogenesis and fatty acid oxidation. It has been shown that daily administration of YC-1102 to mice receiving a HFD prevented an increase in body weight and the accumulation of body fat. YC-1102 administration also reduced TG, TC, and LDL cholesterol levels, as well as glucose and leptin levels, and increased adiponectin levels, thus effectively inhibiting the metabolism of lipids. YC-1102-treated mice showed significant reductions in the mRNA expression of PPARγ and C/EBPα. The levels of PGC-1α involved in energy metabolism increased significantly in the YC-1102-treated mice when compared to the HFD-treated mice. According to the findings of this study, YC-1102 has a dual mechanism that reduces transcription factors that promote the differentiation of adipocytes and increases transcription factors that promote energy consumption.
