In situ localization and tissue distribution of ostreid herpesvirus 1 proteins in infected Pacific oyster, Crassostrea gigas ArchiMer
Martenot, Claire; Segarra, Amelie; Baillon, Laury; Faury, Nicole; Houssin, Maryline; Renault, Tristan.
Immunohistochemistry (IHC) assays were conducted on paraffin sections from experimentally infected spat and unchallenged spat produced in hatchery to determine the tissue distribution of three viral proteins within the Pacific oyster, Crassostrea gigas. Polyclonal antibodies were produced from recombinant proteins corresponding to two putative membrane proteins and one putative apoptosis inhibitor encoded by ORF 25, 72, and 87, respectively. Results were then compared to those obtained by in situ hybridization performed on the same individuals, and showed a substantial agreement according to Landis and Koch numeric scale. Positive signals were mainly observed in connective tissue of gills, mantle, adductor muscle, heart, digestive gland, labial palps, and...

Mitochondrial Ca2+ homeostasis in health and disease Biol. Res.
CAMPANELLA,MICHELANGELO; PINTON,PAOLO; RIZZUTO,ROSARIO.
Although it has long been known that mitochondria possess a complex molecular repertoire for accumulating and releasing Ca2+, only in recent years has a large body of data demonstrated that these organelles promptly respond to Ca2+-mediated cell stimulations. In this contribution, we will review the principles of mitochondrial Ca2+ homeostasis and its signaling role in different physiological and pathological conditions.

MOLECULAR VARIABILITY OF THREE GENES OF POTATO VEIN YELLOW VIRUS INFECTING Solanum tuberosum, USING SINGLE STRAND CONFORMATIONAL POLYMORPHISM Acta biol.Colomb.
CUBILLOS-ABELLO,Karen Andrea; GUZMÁN BARNEY,María Mónica.
Potato yellow vein virus (PYVV), a virus with tripartite RNA (ss+) genome is classified as member of the genus Crinivirus within the family Closteoviridae. PYVV is the causal agent of potato yellow vein disease (PYVD) with yield loss between 25 %-50 % in field. Single strand conformational polymorphism (SSCP) has been reported to estimate variability in different viruses' species. In this study, the molecular variability of PYVV analyzed by SSCP patterns of three genes: major capsid protein (CP), minor capsid protein (CPm), and heat shock protein (Hsp70) obtained from 60 virus isolates from potato plants expressing PYVD. Leaves collected in Nariño, Colombia from 30 Solanum tuberosum Phureja Group (PhG) and 30 from the Andigena Group (AG). Genes amplified...
