Anti-oxidative and Neuroprotective Activities of Pig Skin Gelatin Hydrolysates

In vivo anti-tumor activities of gelatin.

AIM As reported previously, porcine skin gelatin exerted direct anti-tumor effect in vitro and induced anti-tumor peritoneal macrophages in vitro. The present study investigated whether or not the gelatin exerted anti-tumor effect in vivo. METHODS In vitro anti-tumor activities of peritoneal macrophages and the gelatin were evaluated with tritium thymidine uptake by target tumor cells. In viv...

Characterization and Potential Use of Cuttlefish Skin Gelatin Hydrolysates Prepared by Different Microbial Proteases

Composition, functional properties, and in vitro antioxidant activities of gelatin hydrolysates prepared from cuttlefish skin were investigated. Cuttlefish skin gelatin hydrolysates (CSGHs) were obtained by treatment with crude enzyme preparations from Bacillus licheniformis NH1, Bacillus mojavensis A21, Bacillus subtilis A26, and commercial alcalase. All CSGHs had high protein contents, 74.3-7...

Dipeptidyl Peptidase-IV Inhibitory Activity of Peptides in Porcine Skin Gelatin Hydrolysates

Anti-Oxidative and Anti-Inflammation Activities of Pork Extracts

This study was conducted to evaluate the antioxidative and anti-inflammatory effects of boiled pork powder (BPP) and hot water extract powder (HWEP) from 4 cuts of meat from Landrace × Yorkshire × Duroc (LYD). The highest DPPH radical scavenging activities determined were from BPP of Boston butt (13.65 M TE) and HWEP of loin (19.40 M TE) and ham (21.45 M TE). The 2,2-azino-bis-3-ethylbenzothiaz...

Anti-oxidative, anti-tumor-promoting, and anti-carcinogenic activities of adonirubin and adonixanthin.

Anti-oxidative, anti-tumor-promoting, and anti-carcinogenic activities of adonirubin and adonixanthin, which are biosynthetic intermediates from β-carotene to astaxanthin, were investigated. Both adonirubin and adonixanthin showed almost the same activities for inhibition of lipid peroxidation and quenching of singlet oxygen as those of astaxanthin. Furthermore, adonirubin and adonixanthin exhi...
