SUMMARY:Candan Celik\, The effect of microRNA on protein variability and gene expression fidelity
DESCRIPTION:We will discuss about “The effect of microRNA on protein variability and gene expression fidelity”\, Hilfinger\, Andreas\, and Raymond Fan.\, Biophysical journal 122.3 (2023): 537a. \nAbstract \n\nSmall regulatory RNA molecules such as microRNA modulate gene expression through inhibiting the translation of messenger RNA (mRNA). Such post-transcriptional regulation has been recently hypothesized to reduce the stochastic variability of gene expression around average levels. Here we quantify noise in stochastic gene expression models with and without such regulation. Our results suggest that silencing mRNA post-transcriptionally will always increase rather than decrease gene expression noise when the silencing of mRNA also increases its degradation as is expected for microRNA interactions with mRNA. In that regime we also find that silencing mRNA generally reduces the fidelity of signal transmission from deterministically varying upstream factors to protein levels. These findings suggest that microRNA binding to mRNA does not generically confer precision to protein expression

SUMMARY:(Rescheduled: 3/22 -> 3/24) Stefan Bauer\, Neural Causal Models for Experimental Design
DESCRIPTION:Abstract: Many questions in everyday life as well as in research are causal in nature: How would the climate change if we lower train prices or will my headache go away if I take an aspirin? Inherently\, such questions need to specify the causal variables relevant to the question and their interactions. However\, existing algorithms for learning causal graphs from data are often not scaling well both with the number of variables or the number of observations. This talk will provide a brief introduction to causal structure learning\, recent efforts in using continuous optimization to learn causal graphs at scale and systematic approaches for causal experimental design at scale.
