Research Article: Selenoprotein P Controls Oxidative Stress in Cornea

Date Published: March 29, 2010 Publisher: Public Library of Science Author(s): Akihiro Higuchi, Kazuhiko Takahashi, Masaki Hirashima, Tetsuya Kawakita, Kazuo Tsubota, Shukti Chakravarti. Abstract: The ocular surface is always attacked by oxidative stress, and cornea epithelial cells are supposed to have their own recovery system against oxidative stress. Therefore we hypothesized that tears supply key … Continue reading
