The Molecular Mechanism of Polyphenols with Anti-Aging Activity in Aged Human Dermal Fibroblasts Abstract Skin is the largest organ in the body comprised of three different layers including the epidermis, dermis, and hypodermis. The dermis is mainly composed of dermal fibroblasts and extracellular matrix (ECM), such as collagen and elastin, which are strongly related to skin elasticity and firmness. Skin is continuously exposed to different kinds of environmental stimuli. For example, ultraviolet (UV) radiation, air pollutants, or smoking aggravates skin aging. These external stimuli accelerate the aging process by reactive oxygen species (ROS)-mediated signaling pathways and even cause aging-related diseases. Skin aging is characterized by elasticity loss, wrinkle formation, a reduced dermal-epidermal junction, and delayed wound healing. Thus, many studies have shown that natural polyphenol compounds can delay the aging process by regulating age-related signaling pathways in aged dermal fibroblasts. This review first highlights the relationship between aging and its related molecular mechanisms. Then, we discuss the function and underlying mechanism of various polyphenols for improving skin aging. This study may provide essential insights for developing functional cosmetics and future clinical applications.

The relationship between polyamines, NMDA, and depression in suicide completers. - **Polyamines and Depression in Suicide Completers:**Spermidine has been associated with suicide completers. Studies examining gene expression in the brains of mood-disordered suicide completers revealed altered expression of several polyamine-related genes, including spermidine/spermine N1-acetyltransferase, spermine oxidase, and spermine synthase1. These findings highlight the dysregulation of the polyamine system in suicide and its importance in the neurobiology of this complex phenomenon. - **NMDA and Depression in Suicide Completers:** - It is known that NMDA receptors play a crucial role in depression and suicide. brain polyamine levels are altered in Alzheimer's disease polyamine transport, accumulation, and release in brain The polyamine transporter Slc18b1(VPAT) is important for both short and long time memory and for regulation of polyamine content in the brain polyamine catabolism is enhanced after traumatic brain injury polyamine metabolism in different pathological states of the brain Overview of the brain polyamine -stress-response: regulation, development, and modulation by lithium and role in cell survival polyamine metabolism and function in brain polyamine modification increases the permeability of proteins at the blood‐nerve and blood‐brain barriers Dysregulation of multiple metabolic networks related to brain transmethylation and polyamine pathways in Alzheimer disease: A targeted metabolomic and … Modification of biodistribution and brain uptake of copper bis (thiosemicarbazonato) complexes by the incorporation of amine and polyamine functional groups The antistress effect of ginseng total saponin and ginsenoside Rg3 and Rb1 evaluated by brain polyamine level under immobilization stress Pharmacological characterisation and autoradiographic distribution of polyamine -sensitive [3H] ifenprodil binding sites in the rat brain Attenuation of brain Edema, Blood-brain Barrier Breakdown, and injury Volume by Ifenprodil, a polyamine -Site N-Methyl-d-aspartate Receptor Antagonist, after … Contribution of polyamine oxidase to brain injury after trauma polyamine reutilization and turnover in brain polyamine metabolism in brain tumours: diagnostic relevance of quantitative biochemistry Metabolomic studies identify changes in transmethylation and polyamine metabolism in a brain -specific mouse model of tuberous sclerosis complex polyamine uptake, binding and release in rat brain Arginase and arginine decarboxylase–where do the putative gate keepers of polyamine synthesis reside in rat brain ? polyamine metabolism in transient focal ischemia of rat brain Effects of MDL 72527, a specific inhibitor of polyamine oxidase, on brain edema, ischemic injury volume, and tissue polyamine levels in rats after temporary middle … Changes in polyamine levels in rat brain after systemic kainic acid administration: relationship to convulsant activity and brain damage Developmental regulation of the brain polyamine -stress-response In Situ Metabolomics of the Honeybee brain : The Metabolism of l-Arginine through the polyamine Pathway in the Proboscis Extension Response (PER) Maternal behavior as a regulator of polyamine biosynthesis in brain and heart of the developing rat pup Ornithine decarboxylase, the rate-limiting enzyme of polyamine synthesis, modifies brain pathology in a mouse model of tuberous sclerosis complex Depletion of 9L rat brain tumor cell polyamine content by treatment with D, L-α-difluoromethylornithine inhibits proliferation and the G1 to S transition Effect of polyamine depletion on chromatin structure in U-87 MG human brain
