catalpol/atrophy

The protective effect of an iridoid catalpol extracted and purified from the traditional Chinese medicinal herb Rehmannia glutinosa on the neuronal degeneration of nigral-striatal dopaminergic pathway was studied in a chronic 1-methyl-4-phenyl-1,2,3,4-tetrahydropyridine (MPTP)/probenecid C57BL/6

BACKGROUND Chondrocyte dysfunction and apoptosis are 2 major features during the progression of osteoarthritis. Catalpol, an iridoid glycoside isolated from the root of Rehmannia, is a valuable medication with anti-inflammatory, anti-oxidative, and anti-apoptotic effects in various diseases.

The purpose of this work is to study the effect of catalpol, an iridoid from Rehmannia glutinosa on neurodegenerative changes induced by beta-amyloid peptide Abeta(25-35) or Abeta(25-35)+ibotenic acid and the underlying mechanism. Results showed that catalpol significantly improved the memory

Catalpol has been shown to rescue neurons from kinds of damage in vitro and in vivo in previous reports. However, the effect of catalpol on the nitric oxide (NO) system via MAPKs signaling pathway of mesencephalic neurons largely remains to be verified. The current study examined that whether

The degeneration of dopaminergic (DA) neurons in Parkinson's disease (PD) is related to inflammation and oxidative stress. Anti-inflammatory agents could reduce the risk or slow the progression of PD. Catalpol, an iridoid glycoside extracted from the roots of Rehmannia radix, has been

Rehmanniae Radix Praeparata (RR, named as Shudihuang in traditional Chinese medicine), the steamed roots of Rehmannia glutinosa Libosch (Scrophulariaceae), has been demonstrated to have anti-diabetic and anti-osteoporotic activities. This study aimed to explore the protective effect and

Nine autosomal dominant spinocerebellar ataxias (SCAs) are caused by an abnormal expansion of CAG trinucleotide repeats that encodes a polyglutamine (polyQ) tract within different genes. Accumulation of aggregated mutant proteins is a common feature of polyQ diseases, leading to progressive neuronal

Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common age-related neurodegenerative disorders, affecting several millions of aged people globally. Among these disorders, AD is more severe, affecting about 7% of individuals aged 65 and above. AD is primarily a dementia-related
