The complete chloroplast genome sequences of four Liparis species (Orchidaceae) and phylogenetic implications.

Liparis Richard (Malaxideae, Epidendroideae) is a large and diverse genus of the family Orchidaceae, the taxonomy of which is complicated and controversial. In this study, we sequenced, assembled and analyzed four complete chloroplast genomes of Liparis species including L. kumokiri, L.

Structural characterization of Platanthera ussuriensis chloroplast genome and comparative analyses with other species of Orchidaceae.

Background: The genus Tulotis has been classified into the genus Platanthera in the present taxonomic studies since the morphological characteristics of this genus is very similar to that of Platanthera. Platanthera ussuriensis, formerly named as Tulotis ussuriensis, is a small terrestrial orchid species and has been listed as wild plant under State protection (category II) in China. An improved understanding of the genomic information will enable future applications of conservation strategy as well as phylogenetic studies for this rare orchid species.

Peptidomic analysis of pilose antler and its inhibitory effect on triple-negative breast cancer at multiple sites.

Pilose antler (PA) is a traditional Chinese functional food that has been reported to inhibit breast cancer; however, the specific substances that exert this effect and the underlying mechanisms remain unknown. This study aims to identify the specific proteins in PA water-soluble polypeptides (PAWPs) that are involved in cancer inhibition and determine the effects of PAWPs on triple-negative breast cancer in mice. In this study, peptidomic analysis of 105 varieties of polypeptides from PAWPs was carried out using LC-MS, 22 of which had functions that could potentially suppress tumors, including endopeptidase inhibitors, metal ion-binding proteins, angiogenesis inhibitors, intercellular adhesion proteins, and extracellular matrix repair proteins.
