Neuronal migration and lamina-specific primary afferent projections are crucial for establishing spinal cord circuits, but the underlying mechanisms are poorly understood. Here, we report that in mice lacking Dcc (deleted in colorectal cancer), some early-born neurons could not migrate ventrally in the spinal cord. Conversely, forced expression of Dcc caused ventral migration and prevented dors...

Neuropilin-1 (Nrp1) encodes the transmembrane cellular receptor neuropilin-1, which is associated with cardiovascular and neuronal development and was within the peak SNP interval on chromosome 8 in our prior GWAS study on age-related hearing loss (ARHL) in mice. In this study, we generated and characterized an inner ear-specific Nrp1 conditional knockout (CKO) mouse line because Nrp1 constitut...

BACKGROUND To investigate the effects of semaphorin 3A (sema 3A) on cardiac autonomic regulation and subsequent ventricular arrhythmias (VAs) in post-infarcted hearts. METHOD AND RESULTS In order to explore the functions of sema 3A in post-infarcted hearts, lentivirus-Sema 3A-shRNA and negative control vectors were delivered to the peri-infarcted myocardium rats respectively. Meanwhile, recom...

Bone metastasis is the most common complication in patients with solid tumors. Osteoclastogenesis and bone resorption contribute to the pathophysiology of osteoblastic bone metastasis, likewise with osteolytic bone metastasis types. Semaphorin 3A (Sema 3A) has been shown to inhibit RANKL-induced immunoreceptor tyrosinebased activation motif signaling and osteoclastic differentiation, as well as...
