Title	Multiomic Profile Integration Reveals Early Signatures of Amyotrophic Lateral Sclerosis and Suggests the MAPK Pathway as a Therapeutic Target
Description	Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease and still lacks effective disease-modifying treatments. Here, we performed a multiomic analysis of the prefrontal cortex from 51 sporadic ALS patients and 50 control subjects, as well as from four transgenic mouse models of C9orf72-, SOD1-, TDP-43-, and FUS-ALS to characterize early disease mechanisms in ALS. An integrated analysis of transcriptomes, (phospho-)proteomes, and miRNAomes revealed marked sex-specific differences, more pronounced in males. We identified four transcriptome-based sALS-subclusters that are driven by pathways involved in mitochondrial respiration, synaptic function, immune response and transcription. Diffusion pseudo time estimation suggested that these clusters may represent temporal states in disease progression. Individual omics and multifactorial factor analysis revealed the mitogen-activated protein kinase (MAPK) pathway as a disease-relevant mechanism. Its modulation by trametinib in vitro and in vivo validated MEK2 as an auspicious therapeutic target for a subgroup of ALS patients.
