This 4-year PhD studentship is offered in Dr Folkert van Werven’s Group based at the Francis Crick Institute (the Crick).
Alternative mRNA isoforms and long noncoding RNAs (lncRNA) and make up a large fraction of the transcriptome and play key functions in cell-fate programming. These transcripts often initiate upstream of coding gene promoters from alternative transcription start sites (TSS) where they can regulate gene expression in cis through transcription-coupled chromatin alterations. How, when and where transcription of alternative cis-acting RNAs regulates local gene expression remains poorly understood?
In my laboratory, we use budding yeast as a model for cell differentiation to study the usage of alternative transcripts. In particular, we use yeast gametogenesis or sporulation as a model . Over the years, we have studied how alternative transcripts regulate local gene expression at single loci as well as genome-wide scale [2-4]. We have developed high-resolution quantitative approaches to study the alternative transcriptome. Recently, we identified thousand alternative TSSs are upregulated specifically during distinct cell fate transitions giving rise to long upstream mRNA isoforms or long noncoding RNAs. Importantly, transcription from alternative upstream TSSs is associated with different regulatory outcomes for the expression of canonical mRNAs. However, little is understood about why in some cases alternative transcripts lead to activation or repression of gene expression. The next challenge will be to dissect the mechanisms that mediate gene regulation by alternative transcripts.
We are interested in candidates with various backgrounds. Especially, candidates with backgrounds in molecular biology, biochemistry and genomics, but also computational biology would be suitable. The most important is that you have a strong curiosity towards basic sciences.
