Viral Metagenomic Profiling of Croatian Bat Population Reveals Sample and Habitat Dependent Diversity.

To date, the microbiome, as well as the virome of the Croatian populations of bats, was unknown. Here, we present the results of the first viral metagenomic analysis of guano, feces and saliva (oral swabs) of seven bat species (, , , , , and ) conducted in Mediterranean and continental Croatia. Viral nucleic acids were extracted from sample pools, and analyzed using Illumina sequencing.

Molecular and serological survey of lyssaviruses in Croatian bat populations.

Background: Rabies is the only known zoonotic disease of bat origin in Europe. The disease is caused by species belonging to the genus Lyssavirus. Five Lyssavirus species, i.

Abrupt telomere shortening in normal human fibroblasts.

Aging is one of the most basic properties of living organisms. Abundant evidence supports the idea that cell senescence underlies organismal aging in higher mammals. Therefore, examining the molecular mechanisms that control cell and replicative senescence is of great interest for biology and medicine.

Telomerase regulation at the crossroads of cell fate.

Telomeres are specialized structures at the ends of eukaryotic chromosomes and are crucial for genome stability, cell growth control and carcinogenesis. Normally, they protect chromosomes from end to end fusion, degradation and recombination. Telomerase is a ribonucleoprotein essential for maintenance of telomeres and it is active in germ cells, stem cells and approximately 90% of cancers but not in most normal somatic cells.

Telomere dynamics and genome stability in the human pancreatic tumor cell line MIAPaCa-2.

Telomeres are specialized structures found at the ends of eukaryotic chromosomes serving as guardians of genome stability. In normal cells telomeres shorten with each cell division, but immortal cells undergoing multiple divisions constantly have to maintain telomere lengths above a critical level. This is accomplished either through expression of telomerase or the alternative recombination pathway (ALT).
