mRNA decapping function in neuronal cells regulates neurosecretion and intertissue signaling, affecting developmental and ageing processes in two model organisms.
Brain ventricular astrogliosis and neuroinflammation precede scoliosis onset in the zebrafish rpgrip1l ciliary mutant and anti-inflammatory treatment drastically reduces scoliosis while correcting urotensin related peptide level is ineffective.
Class 1 histone deacetylase (HDAC) inhibitor MS-275 enhances the efficacy of glucagon-like peptide 1 receptor (GLP-1R) therapy for glycemic control and reduction of obesity.
Dhh1, Pat1, and Lsm1 target subsets of cellular mRNAs for decapping via interactions of these regulatory proteins with the C-terminal domain of Dcp2, the catalytic component of the decapping enzyme.
Reduced energy expenditure in obesity may result from reduced sensitivity to sympathetic activation due to inflammation-generated signals in adipose tissue.

The structural model of hnRNP A1 shows that it can bind with both RRMs to RNA, which is shown to be relevant for the SMN2 exon 7 splicing mechanism in vivo.
