Huntington's disease (HD) is a devastating neurodegenerative disorder caused by an expansion of CAG trinucleotide repeats encoding for polyglutamine (polyQ) in the huntingtin (Htt) gene. Despite considerable effort, the mechanisms underlying the toxicity of the mutated Htt protein remains largely uncertain. To identify novel therapeutic targets, we recently(More)
Stroke is pathologically associated with oxidative stress, protein damage, and neuronal loss. We previously reported that overexpression of a ubiquitin-like protein, ubiquilin-1 (Ubqln), protects neurons against ischemia-caused brain injury, while knockout of the gene exacerbates cerebral ischemia-caused neuronal damage and delays functional recovery.(More)
Ubiquilin-1 (Ubqln1), a ubiquitin-like protein, is implicated in a variety of pathophysiological processes, but its role in mediating body weight gain or metabolism has not been determined. Here, we demonstrate that global overexpression of Ubqln1 in a transgenic (Tg) mouse reduces the animal's body weight gain. The decreased body weight gain in Tg mice is(More)
Alzheimer's disease (AD) is one of the most common neurodegenerative diseases and is considered to be the main cause of cognitive impairment in elderly people. The major symptom of AD is progressive dementia that eventually results in dysfunction of daily life. Due to the fact that AD has a long period of incubation before clinical symptoms emerge, the(More)
Ubiquilin-1 (Ubqln1) is a ubiquitin-like protein that has been implicated in Alzheimer's disease (AD). However, whether Ubqln1 modulates learning and memory and alters AD-like behavior and/or pathology has not been determined in animal models. To understand the function of Ubqln1 in vivo, we previously generated Ubqln1 transgenic (TG) mice that overexpress(More)
