Exploring transcriptomic and genomic latent variable correction approaches in differential expression analysis

Abstract Background Differential expression analysis is a central tool for studying the biological processes altered in human diseases via transcriptomic signatures. However, transcriptomic datasets are systematically confounded by latent variables from two distinct sources: unme...

Lateral sclerosis in amyotrophic lateral sclerosis is an upper motor neuron distal axonopathy (“dying back”): a clinical-neuropathological study

Abstract The hallmark neuropathological feature of upper motor neuron (UMN) degeneration in amyotrophic lateral sclerosis (ALS) is the “sclerosis” of the lateral corticospinal tract (CST)—the major axonal pathway connecting UMNs to lower motor neurons (LMNs). However, few studies...
