Abstract
Brevinins exhibit a wide range of structural features and strong biological activities. Brevinin-2, derived from several amphibians, has shown antimicrobial activities. However, little is known about the wound-healing activity of brevinin-2. In this study, brevinin-2 cDNA was identified from the skin transcriptome of the dark-spotted frog (Pelophylax nigromaculatus) and it comprises a signal peptide, a propeptide, and a mature peptide. Sequence alignment with brevinin-2 derived from other amphibians showed variability of the mature peptide, and the presence of a C-terminal cyclic heptapeptide domain (Cys-Lys-Xaa4-Cys) in the mature peptide. Dark-spotted frog brevinin-2 belonged to the brevinin-2 cluster and was closely related to brevinin-2HB1 from Pelophylax hubeiensis. Synthetic dark-spotted frog brevinin-2 mature peptide (brevinin-2PN) exhibited antibacterial activity against several pathogens by destroying cell membrane integrity and hydrolysis of genomic DNA. Brevinin-2PN exhibited significant wound-healing activity by accelerating the healing of human skin fibroblast cell scratches, influencing cell migration, and stimulating gene expression of growth factors.

Abstract
Rana zhenhaiensis is a species of frog within the family Ranidae. In this study, its complete mitochondrial genome was characterized by high-throughput sequencing technology. It is 19,205 bp long with an overall AT content of 55.2% and includes 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and 1 control region. Besides, a 26-bp-long origin of L-strand replication (OL) is present between tRNA-Asn and tRNA-Cys. Our findings will be useful for the detailed study of mitogenome evolution and the phylogenetic relationships of the genus Rana and related taxa.

Abstract
Antimicrobial peptides (AMPs) were previously isolated from the skin of the Ryukyu brown frog Rana okinavana. However, this species has recently been reclassified as two species, i.e., Rana kobai and Rana ulma. As a result, it was determined that AMPs isolated from R. okinavana were in fact products of R. kobai, but not of R. ulma. In the present study, we collected skin samples from the species R. ulma and cloned twelve cDNAs encoding AMP precursors for the acyclic brevinin-1ULa--1ULf, the temporin-ULa-ULc, ranatuerin-2ULa, japonicin-1ULa, and a novel peptide using reverse-transcription polymerase chain reaction techniques. The deduced amino acid sequence of the novel peptide had a high similarity to those of Rana chensinensis chensinin-1CEa--1CEc, which were cloned by Zhao et al. ( 2011 ), but had a low similarity with R. chensinensis chensinin-1, which was cloned by Shang et al. ( 2009 ). To avoid confusion with these two different chensinin-1 families, we termed our peptide ulmin-1. Among these peptides, we focused on two peptides, brevinin-1ULf and ulmin-1ULa, and examined the antimicrobial and cytotoxic activity of their synthetic replicates. In broth microdilution assays, growth inhibitory activities against Staphylococcus aureus, Bacillus cereus, and Candida albicans were detected for brevinin-1ULf but not for ulmin-1ULa, whereas scanning electron microscopic observations revealed that both peptides induce morphological abnormalities in these microbes. In addition, binding activity of ulmin-1ULa to the bacterial cell wall component lipoteichoic acid was higher than that of brevinin-1ULf. In contrast, hemolytic and cytotoxic activities of brevinin-1ULf were stronger than those of ulmin-1ULa.
