Singapore scientists discover new RNA processing pathway important in human embryonic stem cells

man induced pluripotent stem cells also)."

Prof Eran Meshorer from the Department of Genetics at the Hebrew University of Jerusalem added, "In recent years, a growing number of papers focusing on the transcriptional regulators that control embryonic stem cell biology have been published. However, the link between RNA splicing and pluripotency has only very recently emerged and the factors that regulate splicing and alternative splicing in ES cells are unknown. The paper by Ng Huck Hui and colleagues now shows that the splicing regulator SON, previously identified in a screen conducted by the same group for novel pluripotency-related factors, regulates the splicing of several key pluripotency genes, linking splicing with stem cell biology and pluripotency. This paper provides a major step towards a more complete understanding of the mechanisms controlling pluripotency and self-renewal, and calls for the identification of additional splicing regulators in ES cells. It is also tempting to speculate that SON and other splicing-related proteins may assist in converting somatic cells into pluripotent cells in the process of reprogramming." Prof Meshorer is the winner of the 2013 Sir Zelman Cowen Universities Fund Prize for Medical Research for the extensive and groundbreaking work undertaken in his laboratory to shed light on pluripotency.
