The Phenotypic and Molecular Identification of Phyllospheric Bacteria Possessing Antimicrobial Activity from (Preuss) Stapf.

Background: Unlike plant phytochemicals, little has been done to explore the metabolites from phyllosphere bacterial flora, some of which enabled them to survive interspecific competition through amensalism. This study evaluated the antimicrobial activity of metabolites from Phyllospheric Bacteria (PB) isolated from (FE), against selected bacterial and fungal pathogens. Phenotypic and molecular methods were used to identify the isolated phyllo-microbiota.

Peonidin-3--glucoside and Resveratrol Increase the Viability of Cultured Human hFOB Osteoblasts and Alter the Expression of Genes Associated with Apoptosis, Osteoblast Differentiation and Osteoclastogenesis.

High-throughput RNA-sequencing can determine the impact of nutrients and their combinations on gene transcription levels in osteocytes, and clarify the biological pathways associated with their impact on bone tissues. Previously, we reported that resveratrol (RES) and peonidin-3--glucoside (POG) increased osteoblastogenesis, as well as reduced osteoclastogenesis in transgenic teleost fish models. Here, we perform whole-genome transcriptomic profiling of osteoblasts treated with POG or RES to provide a comprehensive understanding of alterations in gene expression and the molecular mechanisms involved.

Pharmacological Activities and Chemical Stability of Natural and Enzymatically Acylated Anthocyanins: A Comparative Review.

Anthocyanins (ANCs) are naturally occurring water-soluble pigments responsible for conferring red, blue, and purple colors to fruits, vegetables, flowers, and grains. Due to their chemical structure, they are highly susceptible to degradation by external factors, such as pH, light, temperature, and oxygen. Naturally acylated anthocyanins have proven to be more stable in response to external factors and exhibit superior biological effects as compared with their non-acylated analogues.
