Motivation: Regulation of nuclear mRNA export or retention is carried out by RNA elements but the mechanism is not yet well understood. To understand the mRNA export process, it is important to collect all the involved RNA elements and their trans-acting factors.
Results: By hand-curated literature screening we collected, in ExportAid database, experimentally assessed data about RNA elements regulating nuclear export or retention of endogenous, heterologous or artificial RNAs in mammalian cells. This database could help to understand the RNA export language and to study the possible export efficiency alterations owing to mutations or polymorphisms. Currently, ExportAid stores 235 and 96 RNA elements, respectively, increasing and decreasing export efficiency, and 98 neutral assessed sequences.
Availability And Implementation: Freely accessible without registration at http://www.introni.it/ExportAid/ExportAid.html. Database and web interface are implemented in Perl, MySQL, Apache and JavaScript with all major browsers supported.

Thymic mimetic cells are molecular hybrids between medullary-thymic-epithelial cells (mTECs) and diverse peripheral cell types. They are involved in eliminating autoreactive T cells and can perform supplementary functions reflective of their peripheral-cell counterparts. Current knowledge about mimetic cells derives largely from mouse models.

Background: Disorders of lipid metabolism are critical factors in the progression of chronic lymphocytic leukemia (CLL). However, the characteristics of lipid metabolism and related regulatory mechanisms of CLL remain unclear.
Methods: Hence, we identified altered metabolites and aberrant lipid metabolism pathways in patients with CLL by ultra-high-performance liquid chromatography-mass spectrometry-based non-targeted lipidomics.

The extensive mining of bastnasite (CeFCO) has caused pollution of lanthanum (La), cerium (Ce), and fuorine (F) in the surrounding farmland soil, severely threatening the safety of the soil ecosystem. However, the interaction effects of various chemical fractions of La, Ce, and F on the composition of microbial communities are unclear. In our study, high-throughput sequencing was performed based on the pot experiments of four types of combined pollution soils, i.

RNA silencing is a core cellular process that acts to defend the genome against potentially damaging genetic elements such as viruses and transposons. It has been extensively characterized in many eukaryotes and exploited as a tool for determining gene function through removing the activity of specific genes. It has also been used in Phytophthora species to reveal genes involved in different lifecycle stages.
