View SamplesFTY720/Fingolimod, an FDA-approved drug for treatment of multiple sclerosis, has beneficial effects in the CNS that are not yet well understood, independent of its effects on immune cell trafficking. Here we show that FTY720 enters the nucleus where it is phosphorylated by sphingosine kinase 2 (SphK2) and nuclear FTY720-P that accumulates there, binds and inhibits class I histone deacetylases (HDACs) enhancing specific histone acetylations. FTY720 is also phosphorylated in mice and accumulates in various brain regions, including hippocampus, inhibits HDACs and enhances histone acetylation and gene expression programs associated with memory and learning leading to improvement of memory impairment independently of its immunosuppressive actions. Our data suggest that sphingosine-1-phosphate and SphK2 play specific roles in memory functions and that FTY720 may be a useful adjuvant therapy to facilitate extinction of aversive memories.

Genome-wide screen reveals APC-associated RNAs enriched in cell protrusions.
No sample metadata fields
View SamplesThe goal of the study was to identify on a genome-wide scale RNAs that are enriched at the leading edge of migrating cells. For this, we employed a fractionation method in which cells are plated on a microporous filter whose bottom side only is coated with fibronectin. The cells thus polarize and extend pseudopodial protrusions towards the bottom surface. These protruding pseudopodia can then be physically isolated from the bottom surface of the filter and their contents compared with the remaining cell bodies, which are isolated from the upper surface of the filter.

View SamplesThe goal of the study was to identify on a genome-wide scale RNAs that are enriched at the leading edge of migrating cells. For this, we employed a fractionation method in which serum-starved cells are first plated and allowed to spread on a microporous filter. Addition of LPA at the bottom side of the filter induces the cells to polarize and extend pseudopodial protrusions. These protruding pseudopodia can then be physically isolated from the bottom surface of the filter and their contents compared with the remaining cell bodies, which are isolated from the upper surface of the filter.

Screening and validation of lncRNAs and circRNAs as miRNA sponges.
Cell line
View SamplesIntensive research in past two decades has uncovered the presence and importance of noncoding RNAs (ncRNAs), which includes microRNAs (miRs) and long ncRNAs (lncRNAs). These two classes of ncRNAs interact to a certain extent, as some lncRNAs bind to miRs to sequester them. Such lncRNAs are collectively called 'competing endogenous RNAs' or 'miRNA sponges'. In this study, we screened for lncRNAs that may act as miRNA sponges using the publicly available data sets and databases. To uncover the roles of miRNA sponges, loss-of-function experiments were conducted, which revealed the biological roles as miRNA sponges. LINC00324 is important for the cell survival by binding to miR-615-5p leading to the de-repression of its target BTG2 LOC400043 controls several biological functions via sequestering miR-28-3p and miR-96-5p, thereby changing the expressions of transcriptional regulators. Finally, we also screened for circular RNAs (circRNAs) that may function as miRNA sponges. The results were negative at least for the selected circRNAs in this study. In conclusion, miRNA sponges can be identified by applying a series of bioinformatics techniques and validated with biological experiments.
