Decreases of collagen fibers and the disappearance of oxytalan fibers are typical symptoms of photoaged skin. Although a low quality of mitochondria (MT) in photoaged skin cells has been observed, it is unknown whether the decreased quality of MT is

Intracellular oxidative stress induced by calcium influx initiates the activation of phagocytosis in keratinocytes accumulating at S-phase of the cell cycle after UVB irradiation

Autor: Yuri Okano, Yuki Sato, Yushi Katsuyama, Hitoshi Masaki

Publikováno v: Journal of dermatological science. 103(1)

Background Phagocytosis is an essential process that maintains cellular homeostasis. In the epidermis, the phagocytosis of melanosomes into keratinocytes is important to protect their DNA against damage from ultraviolet B (UVB) radiation. Furthermore

3-O-Glyceryl-2-O-hexyl Ascorbate Suppresses Melanogenesis through Activation of the Autophagy System

Autor: Masato Yoshioka, Yuri Okano, Norihisa Taira, Hitoshi Masaki, Yushi Katsuyama

Publikováno v: Biological and Pharmaceutical Bulletin. 41:824-827

The formation of skin pigmentation requires multiple steps, namely the activation of melanocytes, the synthesis of melanin, the transport of melanosomes to the tips of melanocyte dendrites and the transfer of melanosomes from melanocytes to surroundi

3‐O‐Glyceryl‐2‐O‐hexyl ascorbate suppresses melanogenesis by interfering with intracellular melanosome transport and suppressing tyrosinase protein synthesis

Autor: Norihisa Taira, Masato Yoshioka, Hitoshi Masaki, Yuri Okano, Yushi Katsuyama

Publikováno v: Journal of Cosmetic Dermatology. 17:1209-1215

SummaryBackground Ascorbic acid (AsA) has multifunctional benefits on skin beauty, such as the reduction in oxidative stress and the induction of collagen production. Among them, the prevention and improvement of skin pigmentation by AsA is a most im
