Collagen peptide and vitamin C additively attenuate age-related skin atrophy in Sod1-deficient mice.
Shuichi Shibuya,Yusuke Ozawa,Toshihiko Toda,Kenji Watanabe,Chisa Tometsuka,Takayuki Ogura,Yoh-ichi Koyama,Takahiko Shimizu +7 more
TL;DR: It is demonstrated that CP and a VC derivative additively corrected age-related skin thinning via reduced oxidative damage in superoxide dismutase 1 (Sod1)-deficient mice, suggesting that combined treatment with CP and VC is effective in cases of age- related skin pathology.

Collagen-derived peptides modulate CD4+ T-cell differentiation and suppress allergic responses in mice.
Akihiko Nishikimi,Yoh-ichi Koyama,Sayaka Ishihara,Shusaku Kobayashi,Chisa Tometsuka,Masashi Kusubata,Kumiko Kuwaba,Osamu Hayashida,Shunji Hattori,Koko Katagiri +9 more
TL;DR: The effects of collagen‐peptide ingestion on allergic response and the effects ofcollagen‐derived oligopeptides on CD4+ T‐cell differentiation are tested.

Collagen peptide ingestion alters lipid metabolism-related gene expression and the unfolded protein response in mouse liver.
Chisa Tometsuka,Yoh-ichi Koyama,Tomoko Ishijima,Tsudoi Toyoda,Miki Teranishi,Kazushige Takehana,Keiko Abe,Yuji Nakai +7 more
TL;DR: Analysis of DNA microarray analysis of the liver revealed that lipid metabolism in the liver is altered by CP ingestion, and the decrease in blood cholesterol levels in the CP group is not due to enhancement of the steroid metabolic process.
Detection of endogenous and food-derived collagen dipeptide prolylhydroxyproline (Pro-Hyp) in allergic contact dermatitis-affected mouse ear
TL;DR: Pro-Hyp is generated and degraded as part of the rapid synthesis and degradation of collagen in the ear with dermatitis in mice with hapten (2,4-dinitrofluorobenzene)-induced dermatitis.
The Transcription Factor HAND1 Is Involved in Cortical Bone Mass through the Regulation of Collagen Expression.
Noriko Funato,Yuki Taga,Lindsay E. Laurie,Chisa Tometsuka,Masashi Kusubata,Kiyoko Ogawa-Goto +5 more
TL;DR: It is demonstrated that HAND1 regulates bone size and morphology through osteochondroprogenitors, at least partially by suppressing postnatal expression of collagen fibrils in the cortical bones.
