Project description:To optimize the golden snub-nosed monkey genome annotation, one RNA library of mixed tissues from one individual were constructed using the Illumina mRNA-Seq Prep Kit. We sequenced mixed tissues using the Illumina HiSeq 2000 platform.
Project description:By unbiased deep sequencing, we identified a novel, highly divergent polyomavirus, provisionally named MX polyomavirus (MXPyV), in stool samples from children. From Mexico, 12 samples (out of 96) were positive for MxPyV by MXPyV-specific PCR. We used the ViroChip microarray and PCR to screen these 12 samples for co-infection with common diarrheal viruses. Six of 12 MxPyV-positive diarrheal samples tested negative by the ViroChip and PCR, and the other 6 samples were positive for at least one known diarrheal virus. The ViroChip microarray (version 5.0, Viro5AG-60K platform, GPL15905) was used to screen RNA extracts from MX polyomavirus (MXPyV)-positive pediatric diarrheal samples from Mexico for common diarrheal viruses.
Project description:Little is known about the molecular mechanisms underlying mammalian touch transduction. To identify novel candidate transducers, we examined the molecular and cellular basis of touch in one of the most sensitive tactile organs in the animal kingdom, the star of the star-nosed mole. Our findings demonstrate that the trigeminal ganglia innervating the star are enriched in tactile-sensitive neurons, resulting in a higher proportion of light touch fibers and lower proportion of nociceptors compared to the dorsal root ganglia innervating the rest of the body. We exploit this difference using transcriptome analysis of the star-nosed mole sensory ganglia to identify novel candidate mammalian touch and pain transducers. The most enriched candidates are also expressed in mouse somatosesensory ganglia, suggesting they may mediate transduction in diverse species and are not unique to moles. These findings highlight the utility of examining diverse and specialized species to address fundamental questions in mammalian biology.

Project description:To study the gene expression profiles of brown (BAT) and white (WAT) adipose tissues in wild type and LR11-deficeint mice. The four RNA sources, WT scWAT, Lr11 -/- scWAT, WT BAT and Lr11 -/- BAT, were prepared from subcutaneous WAT and BAT from wild-type mice and Lr11 -/- mice, respectively (n=3 each).
