Data in Brief, 29, (2020): 105256, doi:10.1016/j.dib.2020.105256.The amphibian order Caudata, contains several important model species for biological research. However, there is need to generate transcriptome data from representative species of the primary salamander families. Here we describe a de novo reference transcriptome for a terrestrial salamander, Bolitoglossa vallecula (Caudata: Plethodontidae). We employed paired-end (PE) illumina RNA sequencing to assemble a de novo reference transcriptome for B. vallecula. Assembled transcripts were compared against sequences from other vertebrate taxa to identify orthologous genes, and compared to the transcriptome of a close plethodontid relative (Bolitoglossa ramosi) to identify commonly expressed genes in the skin. This dataset should be useful to future comparative studies aimed at understanding important biological process, such as immunity, wound healing, and the production of antimicrobial compounds.This work was funded by a research grant from COLCIENCIAS 569 (GRANT 027-2103) and CODI (Programa Sostenibilidad) 2013–2014 of the University of Antioquia.

    La presente tesis tiene como objetivo optimizar el proceso de destilación, para la obtención del pisco en la Autoridad Autónoma de Majes, donde, actualmente en dicho proceso, no hay un control de temperaturas y un diseño del horno apto para el aprovechamiento de recursos en el proceso, debido a que el método que usan actualmente es el tradicional, y en muchas ocasiones el mosto fermentado que se encuentra dentro del alambique se quema y eso ocasiona que el pisco que se produce contenga imperfecciones. La evaluación que se realizará será de modo comparativo, debido a que se planteará un diseño para optimizar el proceso y poder tener un control equilibrado de la temperatura del horno, y del interior del alambique, para poder aprovechar los recursos y obtener menos desperdicios de la cabeza y la cola del pisco. Para la recolección de datos se utilizó una base de acero inoxidable, ladrillos refractarios, y un termómetro digital. En la obtención de datos se confirmó que la base de acero diseñada, logro realizar un equilibrio en temperaturas en el horno y en el interior del alambique por lo que el mosto fermentado no tuvo ninguna deficiencia y se produjo más litros de pisco.Campus Arequip

    A Tree Frog (\u3cem\u3eBoana pugnax\u3c/em\u3e) Dataset of Skin Transcriptome for the Identification of Biomolecules with Potential Antimicrobial Activities

    Increases in the prevalence of multiply resistant microbes have necessitated the search for new molecules with antimicrobial properties. One noteworthy avenue in this search is inspired by the presence of native antimicrobial peptides in the skin of amphibians. Having the second highest diversity of frogs worldwide, Colombian anurans represent an extensive natural reservoir that could be tapped in this search. Among this diversity, species such as Boana pugnax (the Chirique-Flusse Treefrog) are particularly notable, in that they thrive in a diversity of marginal habitats, utilize both aquatic and arboreal habitats, and are members of one of few genera that are known to mount a robust immunological response against the fungus Batrachochytrium dendrobatidis, which has decimated the population of frogs worldwide. To search for molecules with potential antimicrobial activity, we have assembled and annotated a reference transcriptome from the skin of four wild captured B. pugnax from Antioquia, Colombia. Analysis of potential antimicrobial and immunological components was performed using ontology analyses, we identified several antimicrobial chemokines with particularly strong potential for exhibiting broadscale antimicrobial activities, as well as several genes related to rapid alteration of transcriptional (KRAB zinc finger protein) and phosphorylation (MAPK) responses to exogenous stressors. We also found eight families of transmembrane transport proteins, including sodium, potassium and voltage-dependent calcium channels, which will be invaluable in future studies aimed at more precisely defining the diversity and function of cationic antimicrobial peptides with alpha-helical structures. These data highlight the utility of frogs such as Boana pugnax in the search of new antimicrobial molecules. Moreover, the molecular datasets presented here allow us to expand our knowledge of this species and illustrate the importance of preserving the vast potential of Colombian biodiversity for the identification of useful biomolecules

    In silico selection and evaluation of pugnins with antibacterial and anticancer activity using skin transcriptome of treefrog (Boana pugnax)

    In order to combat bacterial and cancer resistance, we identified peptides (pugnins) with dual antibacterial l–anticancer activity from the Boana pugnax (B. pugnax) skin transcriptome through in silico analysis. Pugnins A and B were selected owing to their high similarity to the DS4.3 peptide, which served as a template for their alignment to the B. pugnax transcriptome, as well as their function as part of a voltage-dependent potassium channel protein. The secondary peptide structure stability in aqueous medium was evaluated as well, and after interaction with the Escherichia coli (E. coli) membrane model using molecular dynamics. These pugnins were synthesized via solid-phase synthesis strategy and verified by Reverse phase high-performance liquid chromatography (RP-HPLC) and mass spectrometry. Subsequently, their alpha-helix structure was determined by circular dichroism, after which antibacterial tests were then performed to evaluate their antimicrobial activity. Cytotoxicity tests against cancer cells also showed selectivity of pugnin A toward breast cancer (MFC7) cells, and pugnin B toward prostate cancer (PC3) cells. Alternatively, flow cytometry revealed necrotic cell damage with a major cytotoxic effect on human keratinocytes (HaCaT) control cells. Therefore, the pugnins found in the transcriptome of B. pugnax present dual antibacterial– anticancer activity with reduced selectivity to normal eukaryotic cells.Fil: Liscano, Yamil.

    Using Transcriptomics to Enable a Plethodontid Salamander (\u3cem\u3eBolitoglossa ramosi\u3c/em\u3e) for Limb Regeneration Research

    Background: Tissue regeneration is widely distributed across the tree of life. Among vertebrates, salamanders possess an exceptional ability to regenerate amputated limbs and other complex structures. Thus far, molecular insights about limb regeneration have come from a relatively limited number of species from two closely related salamander families. To gain a broader perspective on the molecular basis of limb regeneration and enhance the molecular toolkit of an emerging plethodontid salamander (Bolitoglossa ramosi), we used RNA-Seq to generate a de novo reference transcriptome and identify differentially expressed genes during limb regeneration. Results: Using paired-end Illumina sequencing technology and Trinity assembly, a total of 433,809 transcripts were recovered and we obtained functional annotation for 142,926 non-redundant transcripts of the B. ramosi de novo reference transcriptome. Among the annotated transcripts, 602 genes were identified as differentially expressed during limb regeneration. This list was further processed to identify a core set of genes that exhibit conserved expression changes between B. ramosi and the Mexican axolotl (Ambystoma mexicanum), and presumably their common ancestor from approximately 180 million years ago. Conclusions: We identified genes from B. ramosi that are differentially expressed during limb regeneration, including multiple conserved protein-coding genes and possible putative species-specific genes. Comparative analyses reveal a subset of genes that show similar patterns of expression with ambystomatid species, which highlights the importance of developing comparative gene expression data for studies of limb regeneration among salamanders
