The RNA cargo in small extracellular vesicles from chicken eggs is bioactive in C57BL/6 J mice and human peripheral blood mononuclear cells .

Small extracellular vesicles (sEVs) and their RNA cargo in milk are bioavailable in humans, pigs, and mice, and their dietary depletion and supplementation elicits phenotypes. Little is known about the content and biological activity of sEVs in foods of animal origin other than milk. Here we tested the hypothesis that sEVs in chicken eggs () facilitate the transfer of RNA cargo from an avian species to humans and mice, and their dietary depletion elicits phenotypes.

MicroRNA Exert Macro Effects on Cancer Bone Metastasis.

Bone metastasis is a deadly complication of cancers arising from many different primary tumor locations. Cross talk between cancer and bone cells is a well-established driver of bone metastasis, and recent work reveals microRNA (miRNA) as key players in this communication. Functional significance of miRNA was first demonstrated in cancer cells and has now also been documented in bone cell differentiation and skeletal remodeling.

The Intestinal Transport of Bovine Milk Exosomes Is Mediated by Endocytosis in Human Colon Carcinoma Caco-2 Cells and Rat Small Intestinal IEC-6 Cells.

Background: MicroRNAs play essential roles in gene regulation. A substantial fraction of microRNAs in tissues and body fluids is encapsulated in exosomes, thereby conferring protection against degradation and a pathway for intestinal transport. MicroRNAs in cow milk are bioavailable in humans.

Gene regulation by dietary microRNAs.

MicroRNAs (miRNAs) silence genes through destabilizing mRNA or preventing translation of mRNA, thereby playing an essential role in gene silencing. Traditionally, miRNAs have been considered endogenous regulators of genes, i.e.

Loss of miRNAs during processing and storage of cow's (Bos taurus) milk.

MicroRNAs (miRs, miRNAs) play central roles in gene regulation. Previously, we reported that miRNAs from pasteurized, store-bought bovine milk have biological activity in humans. Here, we assessed the effects of milk processing, storage, somatic cell content, and handling by consumers on the degradation of miRNAs in milk; we also quantified miRNAs in dairy products.

MicroRNAs are absorbed in biologically meaningful amounts from nutritionally relevant doses of cow milk and affect gene expression in peripheral blood mononuclear cells, HEK-293 kidney cell cultures, and mouse livers.

Background: MicroRNAs (miRNAs) regulate genes in animals and plants and can be synthesized endogenously. In milk, miRNAs are encapsulated in exosomes, thereby conferring protection against degradation and facilitating uptake by endocytosis. The majority of bovine miRNAs have nucleotide sequences complementary to human gene transcripts, suggesting that miRNAs in milk might regulate human genes.

Off-target effects of sulforaphane include the derepression of long terminal repeats through histone acetylation events.

Sulforaphane is a naturally occurring isothiocyanate in cruciferous vegetables. Sulforaphane inhibits histone deacetylases, leading to the transcriptional activation of genes including tumor suppressor genes. The compound has attracted considerable attention in the chemoprevention of prostate cancer.
