Juglans regia L. protects against UVB induced apoptosis in human epidermal keratinocytes

The present study was aimed to investigate the photoprotective effect of the male flower of J. regia L. (MEJR) against ultraviolet-B induced apoptosis in human skin cells. Human skin epidermal keratinocytes were pretreated with the MEJR (80 µg/ml, has been selected after MTT assay), prior to 30 min UVB-irradiation at a dose of 20 mJ/cm2. Mitochondrial membrane potential was evaluated using Rhod...

Niacin protects against UVB radiation-induced apoptosis in cultured human skin keratinocytes

Niacin and its related derivatives have been shown to have effects on cellular activities. However, the molecular mechanism of its reduced immunosuppressive effects and photoprotective effects remains unclear. In this study, we investigated the molecular mechanism of the photoprotective effect of niacin in ultraviolet (UV)-irradiated human skin ke...

Alkannin, HSP70 Inducer, Protects against UVB-Induced Apoptosis in Human Keratinocytes

Alkannin is an active constituent from the root extract of Alkanna tinctoria of the Boraginaceae family and it may have utility as a heat shock protein 70 (HSP70) inducer in living organisms. Here, the effects of alkannin-induced HSP70 on ultraviolet (UV) B (40 mJ/cm(2))-induced apoptosis were investigated in human keratinocyte HaCaT cells. Pretreatment of cells with alkannin (1 µM) caused sign...

Epidermal Expression of Neuropilin 1 Protects Murine keratinocytes from UVB-induced apoptosis

BACKGROUND Neuropilin 1 (NRP1) is expressed on several cell types including neurons and endothelial cells, where it functions as an important regulator in development and during angiogenesis. As a cell surface receptor, NRP1 is able to bind to members of the VEGF family of growth factors and to secreted class 3 semaphorins. Neuropilin 1 is also highly expressed in keratinocytes, but the functio...

Translational repression protects human keratinocytes from UVB-induced apoptosis through a discordant eIF2 kinase stress response

This study delineates the mechanisms by which UVB regulates protein synthesis in human keratinocytes and the importance of translational control in cell survival. Translation initiation is regulated by phosphorylation of eukaryotic initiation factor 2 (eIF2-P) that causes decreased global protein synthesis coincident with enhanced translation of selected stress-related transcripts, such as acti...
