Our fall seminar series goes international
This fall, our seminar series is featuring international scientific leaders.They will give virtual talks and meet with our community.
 
Our seminar series was launched on April 14, 2016, and featured RNA scientists within U-M. It was a great opportunity to learn about each other’s research within U-M. We have progressively expanded our horizons, and invited high-profile researchers from within the U.S. This year, we’re pleased to also have speakers from around the world and, again, a remarkable line-up!
On the occasion of the National Postdoc Appreciation Week, the University of Michigan (U-M) Center for RNA Biomedicine’s community warmly thanks UM’s postdocs for their tremendous contributions to the field of RNA research and to the life of our scientific community.

According to the U-M Postdoctoral Association (UMPDA), an estimated 1,400 to 1,600 postdocs work across the University. They are key contributors to U-M’s research endeavor and to the dynamics of our labs. To thank them all, we interviewed four of them, all passionate about their research and lab work, representative of the entire cohort. Here is a summary of what they had to say about their roles at the U-M.

By integrating our results with prior knowledge, we developed a ‘rulebook’ of key contextual features that differentiate functional vs. non-functional PREs, allowing us to train machine learning models that accurately predict the functional regulation of RNA targets by the human PUM proteins.
Single-Cell Transcriptome Analysis of Colon Cancer Cell Response to 5-Fluorouracil-Induced DNA Damage, Sung Rye Park, Sim Namkoong, Leon Friesen, Chun-Seok Cho, Zac Zezhi Zhang, Yu-Chih Chen, Euisik Yoon, Chang H.Kim, Hojoong Kwak, Hyun Min Kang, Jun Hee Lee, Cell Reports, Volume 32, Issue 8, 25 August 2020, 108077, https://doi.org/10.1016/j.celrep.2020.108077

Highlights
  • Single-cell transcriptome responses to 5FU-induced DNA damage are characterized
  • Transcriptome phenotypes underlying heterogeneous 5FU responses are identified
  • Cell-fate-specific gene expression patterns after 5FU treatment are shown
  • Key observations are reproduced in flow cytometry and other DNA damage treatments

Overall, the findings of this study indicate that magneto‐endosymbionts are an effective tool for in vivo monitoring of cell‐based therapies with potential relevance to many neurological applications.

Illustration: Kinetic fingerprinting with dynamically binding fluorescent antibodies (cyan with red glowing orb) distinguishes between the repetitive binding to a specific target protein (left) and the less repetitive nonspecific binding to other proteins (right) captured on a surface using conventional IgG antibodies (blue Y-shaped molecules, bottom). The highly specific single-molecule detection of this approach provides approximately 100-fold higher sensitivity than conventional protein detection assays such as ELISA.
