A highly prevalent and genetically diversified Picornaviridae genus in South Asian children.

ABSTRACT: Viral metagenomics focused on particle-protected nucleic acids was used on the stools of South Asian children with nonpolio acute flaccid paralysis (AFP). We identified sequences distantly related to Seneca Valley virus and cardioviruses that were then used as genetic footholds to characterize multiple viral species within a previously unreported genus of the Picornaviridae family. The picornaviruses were detected in the stools of >40% of AFP and healthy Pakistani children. A genetically diverse and highly prevalent enteric viral infection, characteristics similar to the Enterovirus genus, was therefore identified substantially expanding the genetic diversity of the RNA viral flora commonly found in children.

Cardioviruses are genetically diverse and cause common enteric infections in South Asian children.

Project description:Cardioviruses cause enteric infections in mice and rats which when disseminated have been associated with myocarditis, type 1 diabetes, encephalitis, and multiple sclerosis-like symptoms. Cardioviruses have also been detected at lower frequencies in other mammals. The Cardiovirus genus within the Picornaviridae family is currently made up of two viral species, Theilovirus and Encephalomyocarditis virus. Until recently, only a single strain of cardioviruses (Vilyuisk virus within the Theilovirus species) associated with a geographically restricted and prevalent encephalitis-like condition had been reported to occur in humans. A second theilovirus-related cardiovirus (Saffold virus [SAFV]) was reported in 2007 and subsequently found in respiratory secretions from children with respiratory problems and in stools of both healthy and diarrheic children. Using viral metagenomics, we identified RNA fragments related to SAFV in the stools of Pakistani and Afghani children with nonpolio acute flaccid paralysis (AFP). We sequenced three near-full-length genomes, showing the presence of divergent strains of SAFV and preliminary evidence of a distant recombination event between the ancestors of the Theiler-like viruses of rats and those of human SAFV. Further VP1 sequencing showed the presence of five new SAFV genotypes, doubling the reported genetic diversity of human and animal theiloviruses combined. Both AFP patients and healthy children in Pakistan were found to be excreting SAFV at high frequencies of 9 and 12%, respectively. Further studies are needed to examine the roles of these highly common and diverse SAFV genotypes in nonpolio AFP and other human diseases.

miRNA expression studies in uveal melanoma (South Asian-Indian population).

Project description:To predict differentially expressed miRNAs between monosomy 3 and disomy 3, and to associate these miRNAs with the clinico-pathological parameters in South Asian Indian population with uveal melanoma (UM). The study consists of six uveal melanoma primary tumour tissues of South Asian-Indian population. These six tumours have been screened for chromosome 3 aberration using Chromogenic in-situ hybridisation (CISH). Thus, sample under the study includes, three each of monosomy 3 and disomy 3. The miRNA profiling was carried out from the tumor sections of formalin-fixed paraffin embedded eyeball samples. miRNA expression profile was obtained in monosomy 3 and disomy 3 samples, analysed by unsupervised analysis (Principal Component Analysis) and supervised analysis (Significance analysis of microarray). The select up-regulated and candidate miRNAs associated with monosomy 3 uveal melanoma tumors were validated further with qRT-PCR (n=86). Thus, this study indicates the role of miRNAs in UM tumor progression and their implication in predetermining the liver metastasis.

A member of a new Picornaviridae genus is shed in pig feces.

Project description:During a study of the fecal microbiomes from two healthy piglets using high-throughput sequencing (HTS), we identified a viral genome containing an open reading frame encoding a predicted polyprotein of 2,133 amino acids. This novel viral genome displayed the typical organization of picornaviruses, containing three structural proteins (VP0, VP3, and VP1), followed by seven nonstructural proteins (2A, 2B, 2C, 3A, 3B, 3C(pro), and 3D(pol)). Given its particular relationship with Parechovirus, we propose to name it "Pasivirus" for Parecho sister clade virus, with "Swine pasivirus 1" (SPaV1) as the type species. Fecal samples collected at an industrial farm from healthy sows and piglets from the same herd (25 and 75, respectively) with ages ranging from 4 to 28 weeks were analyzed for the presence of SPaV1 by one-step reverse transcription (RT)-PCR targeting a 3D region of 151 bp. SPaV1 was detected in fecal samples from 51/75 healthy piglets (68% of the animals) and in none of the 25 fecal samples from healthy sows, indicating that SPaV1 circulates through enteric infection of healthy piglets. We propose that SPaV1 represents the first member of a novel Picornaviridae genus related to parechoviruses.

Rosavirus: the prototype of a proposed new genus of the Picornaviridae family.

Project description:We describe a 8,724-nucleotide-long picornavirus genome encoding a single 2,470-aa polyprotein obtained from the feces of a wild mouse. Rosavirus is genetically closest to the double ORF Dicipivirus found in canine feces that is currently the only picornavirus with a second internal ribosome entry site (IRES). Of note, a section of rosavirus' 5'UTR showed strong sequence and structural conservation with the type II IRES from the Parechovirus and Hungarovirus genera possibly reflecting exchange of genetic modules between genera. Based on genetic distance criteria rosavirus qualifies as prototype of a new genus of the Picornaviridae family.

Complete genome sequence of a highly prevalent isolate of porcine epidemic diarrhea virus in South China.

Project description:A widespread porcine epidemic diarrhea virus (PEDV) occurred in southern China during 2010 to 2012. A virulent field PEDV strain, GD-B, was isolated from a sucking piglet suffering from severe diarrhea in Guangdong, China. We sequenced and analyzed the complete genome of strain GD-B, which will promote a better understanding of the molecular epidemiology and genetic diversity of PEDV field isolates in southern China.

Groundbreaking Anticancer Activity of Highly Diversified Oxadiazole Scaffolds.

Project description:Nowadays, an increasing number of heterocyclic-based drugs found application in medicinal chemistry and, in particular, as anticancer agents. In this context, oxadiazoles-five-membered aromatic rings-emerged for their interesting biological properties. Modification of oxadiazole scaffolds represents a valid strategy to increase their anticancer activity, especially on 1,2,4 and 1,3,4 regioisomers. In the last years, an increasing number of oxadiazole derivatives, with remarkable cytotoxicity for several tumor lines, were identified. Structural modifications, that ensure higher cytotoxicity towards malignant cells, represent a solid starting point in the development of novel oxadiazole-based drugs. To increase the specificity of this strategy, outstanding oxadiazole scaffolds have been designed to selectively interact with biological targets, including enzymes, globular proteins, and nucleic acids, showing more promising antitumor effects. In the present work, we aim to provide a comprehensive overview of the anticancer activity of these heterocycles, describing their effect on different targets and highlighting how their structural versatility has been exploited to modulate their biological properties.

Quantitative isoform-profiling of highly diversified recognition molecules.

Project description:Complex biological systems rely on cell surface cues that govern cellular self-recognition and selective interactions with appropriate partners. Molecular diversification of cell surface recognition molecules through DNA recombination and complex alternative splicing has emerged as an important principle for encoding such interactions. However, the lack of tools to specifically detect and quantify receptor protein isoforms is a major impediment to functional studies. We here developed a workflow for targeted mass spectrometry by selected reaction monitoring that permits quantitative assessment of highly diversified protein families. We apply this workflow to dissecting the molecular diversity of the neuronal neurexin receptors and uncover an alternative splicing-dependent recognition code for synaptic ligands.
