is a temperate brown alga known to exert free radical-scavenging and anti-inflammatory effects. In this study, we investigated the skin-whitening effects of sporophyll extracts (UPEs) in α-melanocyte-stimulating hormone (α-MSH)-stimulated B16F10 melanoma cells. The crude polysaccharide fraction (UPF) was obtained via ethanol precipitation.

It is widely utilized in cosmetic skin solutions, drug delivery, vitreous substitutions, 3D cell cultures, and surgery. In this study, we report the development of a green technology for manufacturing collagen peptides from flatfish skin using ultrasound and enzymatic treatment and a subsequent assessment on skin functionality.

Therefore, this study aimed to develop a yeast extract capable of inhibiting melanoma cells using ultrasound technology, which can lyse the cell walls allowing subsequent rapid yeast extraction. To compare the extraction efficiency across different extraction methods, the total yield, as well as total glucan, α-glucan, and β-glucan yields were measured.

Arctium lappa root is a plant widely used in traditional Chinese medicine (TCM), and Arctium lappa root extract (ALE) has been reported to exhibit anti-inflammatory capacity and to ameliorate endothelial dysfunction. Thus, we hypothesized that ALE would inhibit the early atherosclerotic stage.

However, interest in functional verification and industrial applications of sericin has been growing for several years. We used ultrasonication to simplify the extraction process of the silk peptide under low salt conditions at 20 °C, instead of using the conventional conditions of high salt and temperature.

In muscle development, myoblast proliferation is known to be a first step, and recent studies have reported that an increased irisin level is involved in the promotion of cell proliferation in various cell types, including myoblasts. However, the exact mechanism of action by which irisin promotes myoblast proliferation has not been reported.

In this study, we efficiently synthesized N-benzyl-N-methyl-dodecan-1-amine (BMDA) by the reductive amination method. We evaluated the potential anticancer activities of BMDA against A549 lung cancer cells with cancer stem cell-like phenotypes due to the overexpression of cancer upregulated gene (CUG)2.

Epidemiologic evidence and molecular studies suggest that non-melanoma skin cancer is directly associated with excessive exposure to ultraviolet (UV) radiation. The aim of the present study was to evaluate the inhibitory effects of syringic acid on UVB-induced signaling and skin carcinogenesis, and determine the molecular targets.

Non-small-cell lung cancer (NSCLC) is associated with diverse genetic alterations including mutation of epidermal growth factor receptor (EGFR). Isoliquiritigenin (ILQ), a chalcone derivative, possesses anticancer activities. In the present study, we investigated the effects of ILQ on the growth of tyrosine kinase inhibitor (TKI)-sensitive and -resistant NSCLC cells and elucidated its underlying mechanisms.
