Numerous food-derived natural bioactive peptides have excellent skin wound healing potential. Herein, we reported the capacity of sea cucumber derived tetrapeptides VTPY and VLLY to promote wound healing. Our study revealed that the two peptides significantly contribute to the healing of skin wounds by promoting reepithelialization, collagen and lipid regeneration for skin appendage remodeling, and enhancing angiogenesis both in vitro and in vivo. VTPY and VLLY significantly accelerate the migration of keratinocytes to seal the wound surface, as well as facilitate collagen regeneration by promoting the phosphorylation of EKR and P-38. Meanwhile, VTPY and VLLY further enhance angiogenesis and lipid regeneration via upregulating expression of VEGF and eNOS, and triggering ERK/AKT signaling. VTPY works better than VLLY. These findings indicate that sea cucumber derived tetrapeptide VTPY and VLLY can serve as natural food source-derived candidate for promoting skin wound healing.

如果从1977年汉文版《西藏文艺》~①开始大量发表当代藏族作家的汉语小说创作开始算起,那么当代藏族作家汉语小说已走过40年的历程。如果从1963年益西卓玛在《儿童文学》第2期发表其后来出版的长篇小说《清晨》的一个片段算起~②,那么当代藏族作家汉语小说创作事实上就已走过五十余年的历程。对此,笔者认为,当代藏族作家汉语小说的历史以从1977年记起为最佳,因为当代藏族作家汉语小说有众多作家作品在较为集中的时间段里先后出现时.
