Protozoan parasites of the Trypanosomatidae family can cause devastating diseases in humans and animals, such as Human African Trypanosomiasis or Sleeping Sickness, Chagas disease and Leishmaniasis. Currently, there are molecular assays for detecting parasitic infections and their post-treatment monitoring based on nucleic acid amplification, but there are still certain limitations which limit the...
Over the last decade, circulating microRNAs have received attention as diagnostic and prognostic biomarkers. In particular, microRNA122 has been demonstrated to be an early and more sensitive indicator of drug-induced liver injury than the widely used biomarkers such as alanine aminotransferase and aspartate aminotransferase. Recently, microRNA122 has been used in vitro to assess the cellular toxicity...
The class V POU domain transcription factor Oct4 (Pou5f1) is a pivotal regulator of embryonic stem cell (ESC) self-renewal and reprogramming of somatic cells to induced pluripotent stem (iPS) cells. Oct4 is also an important evolutionarily conserved regulator of progenitor cell differentiation during embryonic development.Here we examine the function of Oct4 homologs in Xenopus embryos and compare...
Maintaining stable differentiated somatic cell function in culture is essential to a range of biological endeavors. However, current technologies, employing, for example, primary hepatic cell culture (essential to the development of a bio-artificial liver and improved drug and toxicology testing), are limited by supply, expense, and functional instability even on biological cell culture substrata...
