Article Abstract
L1 plays a role in neural development. However, it remains unclear how L1 plays this role. In the present study, we have shown extensive outgrowth of long neurites in cerebellar neurons after treatment with either L1 or L1 antibody. Notably, the mRNA level of FGF21 was significantly increased in both L1 and L1 antibody treated neurons compared to control group. Consistently, the neurite outgrowth promoted by L1 was strongly inhibited by siRNA against FGF21 gene or a treatment of cells with FGFR inhibitor. These results demonstrate that FGF21/FGFR signaling promotes the neurite outgrowth in a L1-dependent manner.

Emerging evidence indicates that apelin, an adipokine, plays a critical role in numerous biological functions and may hold potential for therapeutic applications; however, its efficacy is constrained by rapid plasma degradation. Thus, the search for novel apelin analogues with reduced susceptibility to plasma degradation is ongoing. We have previously shown novel modified apelin-13 analogues, providing exciting opportunities for potential therapeutic development against Alzheimer's disease.

Spinal cord injury (SCI) causes irreversible motor deficits due to disrupted lumbar circuitry. However, transcriptional mechanisms in distal lumbar circuits are poorly understood. We identify POU6F1 as a critical transcriptional regulator in spinal lumbar segment (SLS, L3-L5) motor circuit regeneration.

Charcot-Marie-Tooth disease (CMT) is an inherited peripheral neuropathy characterized by sensory dysfunction and muscle weakness, manifesting in the most distal limbs first and progressing more proximal. Over a hundred genes are currently linked to CMT with enrichment for activities in myelination, axon transport, and protein synthesis. Mutations in tRNA synthetases cause dominantly inherited forms of CMT and animal models with CMT-linked mutations in these enzymes display defects in neuronal protein synthesis.

In pancreatic ductal adenocarcinoma (PDAC), worse clinical outcomes are associated with perineural invasion (PNI), a process by which cancer cells surround and invade nerves. Here, we employed whole-transcriptome and single-cell spatial transcriptomics to identify candidate tumor-nerve interactions that promote PNI.

Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by mislocalization and aggregation of proteins in motor neurons. Ataxin-2 (ATXN2), an RNA-binding protein harboring 22-polyglutamine (polyQ) repeats, is a risk factor for ALS, when its polyQ repeats are expanded to 27-33 repeats. However, the physiological function of ATXN2 beyond its role in RNA regulation, and how polyQ expansion in ATXN2 increases risk for ALS, remain unclear.
