NAT10 modulates fatty acid metabolism of palmitate driven MCF7 in ac4C dependent manner
We show that non-toxic exogenous palmitate uptake in MCF7 cells promotes NAT10 expression and NAT10-dependent ac4C RNA modification. It was previously reported that NAT10 modulates the addition of ac4C on RNA transcripts in normal and cancer conditions. However, no study report the impact of NAT10 in palmitate driven cells. Here we performed RNA immunoprecipitation sequencing (RIP-seq) in palmitate loaded MCF7 knockdown with NAT10 siRNA. Based on the pathways and enrichment landscape identified. We found that ac4C peaks of fatty acid metabolic genes including ELOVL6, ACSL1, ACSL3, ACSL4, ACADSB and ACAT1 were significantly decreased upon knockdown with NAT10 siRNA.  Overall, our results revealed the impact of NAT10 as a regulator of fatty acid metabolism in ac4C-dependent manner Overall design: Exogenous palmitate uptake coupled with knockdown using NAT10 siRNA followed by RNA precipitation using ac4C antibody
