Herbal mixture of Platycodon grandiflorum, Cinnamomum cassia, and Asiasarum sieboldii extracts protects against NASH progression via regulation of hepatic steatosis, inflammation, and apoptosis.

Background: Non-alcoholic fatty liver disease (NAFLD, recently renamed as metabolic dysfunction-associated steatotic liver disease [MASLD]) has emerged as one of the most prevalent chronic liver diseases globally. The more severe progressive form of the disease is called nonalcoholic steatohepatitis (NASH, now termed metabolic dysfunction-associated steatohepatitis [MASH]). The rising prevalence of NASH is placing an increasing burden on global healthcare systems also associated with a significant economic costs.

Sinapic Acid Ameliorates REV-ERB α Modulated Mitochondrial Fission against MPTP-Induced Parkinson's Disease Model.

Parkinson's disease (PD) is the second most common neurodegenerative disease worldwide, and accumulating evidence indicates that mitochondrial dysfunction is associated with progressive deterioration in PD patients. Previous studies have shown that sinapic acid has a neuroprotective effect, but its mechanisms of action remain unclear. The neuroprotective effect of sinapic acid was assayed in a PD mouse model generated by the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) as well as in SH-SY5Y cells.

A Novel Cardenolide Glycoside Isolated from Reduces Levels of the Alzheimer's Disease-Associated β-Amyloid Peptides Aβ42 In Vitro.

Elevated levels of the amylo β-proteins (Aβ), particularly Aβ42, are associated with a high risk of Alzheimer's disease (AD). The Aβ proteins are produced from cellular processing of the amyloid precursor proteins (APPs). To identify natural products that block the formation of Aβ-proteins from APPs, we previously screened a library of plant extracts and identified (Apocynaceae) as a potential plant for further research.

The autophagy-regulating effect of AKNS-2 was monitored by analyzing the expression of autophagy-related protein markers in SHSY5Y cells using Western blot and fluorescent protein quenching assays. The neuroprotection of AKNS-2 was tested by using a 1-methyl-4-phenyl-2,3-dihydropyridium ion (MPP)-induced PD model in SH-SY5Y cells and an MPTP-induced PD model in mice.

Narciclasine inhibits LPS-induced neuroinflammation by modulating the Akt/IKK/NF-κB and JNK signaling pathways.

Background: Neuroinflammation is defined as innate immune system activation in the central nervous system, and is a complex response involved in removing pathogens, toxic components, and dead cells by activating microglial cells. However, over-activated microglia have been implicated in the pathogenesis of neurodegenerative diseases, because they release large amounts of neurotoxic factors. Thus, inhibiting microglial activation may represent an attractive approach for preventing neuroinflammatory disorders.

3'-O-Acetyl-24-Epi-7,8-Didehydrocimigenol-3-O-β-DXylopryranoside Decreases Amyloid Beta Production in Amyloid Precursor Protein-Transfected HeLa Cells.

Extracellular beta amyloid (Aβ) plaques are the neuropathological hallmarks of Alzheimer's disease (AD). Accordingly, reducing Aβ levels is considered a promising strategy for AD prevention. 3'-O-acetyl-24-epi-7,8-didehydrocimigenol-3-O-β-D-xylopryranoside significantly decreased the Aβ production and this effect was accompanied with reduced sAPPβ production known as a soluble ectodomain APP fragment through β-secretases in HeLa cells overexpressing amyloid precursor proteins (APPs).

The Parkinson's disease presents with impaired motor functions and loss of dopaminergic neurons. However, the treatment for Parkinson's disease is not established until now.

Protective Effects of Compounds from against Amyloid Beta Production in Vitro and Scopolamine-Induced Memory Impairment in Vivo.

has traditionally been used as an antipyretic, analgesic, and anti-inflammatory agent and as a treatment for uterine and anal prolapse. This study has investigated the potential beneficial effects of this medicinal plant and its components on Alzheimer's disease (AD) with a focus on amyloid beta (Aβ) production and scopolamine-induced memory impairment in mice. An ethanol extract from roots decreased Aβ production in APP-CHO cells [Chinese hamster ovarian (CHO) cells stably expressing amyloid precursor protein (APP)], as determined by an enzyme-linked immunosorbent assay and Western blot analysis.

Substrate-Specific Activation of α-Secretase by 7-Deoxy-Trans-Dihydronarciclasine Increases Non-Amyloidogenic Processing of β-Amyloid Protein Precursor.

Accumulation of β-amyloid (Aβ) in the brain has been implicated in the pathology of Alzheimer's disease (AD). Aβ is produced from the Aβ precursor protein (APP) through the amyloidogenic pathway by β-, and γ-secretase. Alternatively, APP can be cleaved by α-, and γ-secretase, precluding the production of Aβ.

Cerebrospinal Fluid Levels of Autophagy-related Proteins Represent Potentially Novel Biomarkers of Early-Stage Parkinson's Disease.

The roles of autophagy-related proteins as diagnostic or monitoring biomarkers in Parkinson's disease (PD) have not been clearly elucidated. We recruited 32 patients with early-stage PD and 28 control subjects, and evaluated parkinsonian motor symptoms and dopamine transporter imaging data. Cerebrospinal fluid (CSF) levels of LC3B, Beclin1, and LAMP-2 were estimated using ELISAs, and CSF levels of ATG5, ATG7, and p62 were examined by immunoblotting.
