Oral supplementation of anthocyanins-rich haskap () berry (HB) reduces 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK)-induced lung tumorigenesis, cytotoxicity, DNA damage, and modulated inflammation in vitro and in vivo. The procarcinogen NNK is metabolically activated by cytochrome P450 (P450) enzymes, producing reactive metabolites that induce lung carcinogenesis. : Therefore, we hypothesized that the HB-modulated protective effect against NNK could be due to its ability to suppress P450 enzymes.

Angiogenesis is a normal physiological process that also contributes to diabetic retinopathy-related complications and facilitates tumor metastasis by promoting the hematogenic dissemination of malignant cells from solid tumors. Here, we investigated the in vitro, ex vivo, and in vivo anti-angiogenic activity of phloridzin docosahexaenoate (PZ-DHA), a novel ω-3 fatty acid ester of a flavonoid precursor. Human umbilical vein endothelial cells (HUVEC) and human dermal microvascular endothelial cells (HMVEC) treated with a sub-cytotoxic concentration of PZ-DHA to assess in vitro anti-angiogenic activity showed impaired tubule formation on a Matrigel matrix.

Cucumaria frondosa (Gennerus, 1767) or orange-footed sea cucumbers are traditional food and are used as natural sources of anti-diabetic, anti-inflammatory, antioxidant, anti-angiogenic, antimicrobial, and anticancer agents. Currently, the introduction of value-added sea cucumber products to the global market has inspired basic research on frondoside A and other saponins in sea cucumbers. These saponins serve as a means of their chemical defence.

Article Synopsis
  • - Eczema (atopic dermatitis) is a skin condition with causes linked to genetics, immune issues, and environmental factors, making skin barrier dysfunction a key problem.
  • - Current treatments primarily involve emollients and topical medications like corticosteroids; the review highlights new advancements in using plant-based topical applications and their effectiveness.
  • - Studies show that herbal treatments improve symptoms of eczema, decrease inflammation markers, and may reduce side effects associated with conventional treatments by using innovative delivery systems like nanocarriers.
