Abstract
Background Alzheimer's disease (AD), the most common form of dementia, is characterized by memory loss and the abnormal accumulation of senile plaques composed of amyloid-β (Aβ) protein. Trichosanthis Semen (TS) is a traditional herbal medicine used to treat phlegm-related conditions. While TS is recognized for various bioactivities, including anti-neuroinflammatory effects, its ability to attenuate AD remains unknown. Objective To evaluate the effects of TS extract (TSE) on neuronal damage, Aβ accumulation, and neuroinflammation in AD models. Methods Thioflavin T and western blot assays were used to assess effects on Aβ aggregation in vitro. TS was treated to PC12 cells with Aβ to assess the neuroprotective effects. Memory functions and histological brain features were investigated in TSE-treated 5×FAD transgenic mice and mice with intracerebroventricularly injected Aβ. Results TSE disrupted Aβ aggregation and increased the viability of cells and phosphorylation of both protein kinase B (Akt) and extracellular signal-regulated kinase (ERK) in vitro. TSE treatment also suppressed the accumulation of Aβ plaques in the brain of 5×FAD mice, protected neuronal cells in both the subiculum and medial septum, and upregulated Akt/ERK phosphorylation in the hippocampus. Moreover, TSE ameliorated the memory decline and glial overactivation observed in 5×FAD mice. As assessing whether TS affect Aβ-induced neurotoxicity in the Aβ-injected mice, the effects of TS on memory improvement and neuroinflammatory inhibition were confirmed. Conclusions TSE disrupted Aβ aggregation, protected neurons against Aβ-induced toxicity, and suppressed neuroinflammation, suggesting that it can suppress the development of AD.

Mol Neurobiol 2023; 60:7196-7207. [PMID: 37542650 DOI: 10.1007/s12035-023-03544-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 07/27/2023] [Indexed: 08/07/2023]
Abstract
Neuroinflammation and synaptic damage are important etiologies associated with the progression of Alzheimer's disease (AD). Linderae Radix (LR) has antioxidant and anti-inflammatory properties. This study investigated whether LR attenuates microglia activation-mediated neuroinflammation and synaptic degeneration and improves AD pathological phenotypes induced by amyloid beta oligomers (AβO) or lipopolysaccharide (LPS) toxicity. For in vitro studies, we treated LR to AβO-stimulated HT22 cells or LR LPS-stimulated BV2 cells. For in vivo studies, we administered LR to mice and AβO was injected by stereotaxic to induce cognitive impairment, neuroinflammation, and synaptic loss. We found that LR increased the cell viability reduced by AβO. Moreover, LR inhibited pro-inflammatory mediators such as nitric oxide (NO), inducible NO synthase (iNOS), and cyclooxygenase-2 (COX-2), and downregulated p38 mitogen-activated protein kinase (MAPK) signaling in BV2 cells. Behavioral assessments demonstrated that LR administration significantly improved cognitive decline induced by AβO-injection. Furthermore, we found that microglia activation increased, and the expression of synaptic proteins decreased in the hippocampus of the AβO-injected group, which was alleviated in the LR-treated group. These findings suggest that LR may be a potential candidate for protection against neuroinflammation and synaptic loss, and may prevent or delay AD progression.

Jiawei Yanghe Decoction suppresses breast cancer by regulating immune responses via JAK2/STAT3 signaling pathway. JOURNAL OF ETHNOPHARMACOLOGY 2023; 316:116358. [PMID: 36933872 DOI: 10.1016/j.jep.2023.116358] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 02/18/2023] [Accepted: 03/03/2023] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jiawei Yanghe Decoction (JWYHD) is a widely used traditional Chinese medicine prescription in the clinical setting for the treatment of autoimmune diseases. Many studies showed that JWYHD has anti-tumor activities in cell and animal models. However, the anti-breast cancer effects of JWYHD and the underlying mechanisms of action remain unknown. AIM OF STUDY This study aimed to determine the anti-breast cancer effect and reveal the underlying mechanisms of action in vivo, in vitro and in silico. MATERIALS AND METHODS Orthotopic xenograft breast cancer mouse model and inflammatory zebrafish model were used to observe the anti-tumor effect and immune cell regulation of JWYHD. Moreover, the anti-inflammatory effect of JWYHD were evaluated by the expression of RAW 264.7 cells. JWYHD active ingredients were obtained by UPLC-MS/MS and potential targets were screened by network pharmacology. The therapeutic targets and signaling pathways predicted by computer were assessed by Western blot, real-time PCR (RT-PCR), immunohistochemistry (IHC) staining, and Enzyme-linked immunosorbent assays (ELISA) to explore the therapeutic mechanism of JWYHD against breast cancer. At last, Colivelin and Stattic were used to explore the effect of JWYHD on JAK2/STAT3 pathway. RESULTS JWYHD significantly decreased the tumor growth in a dose-dependent manner in the orthotopic xenograft breast cancer mouse model. Flow cytometry and IHC results indicated that JWYHD decreased the expressions of M2 macrophages and Treg while increasing M1 macrophages. Meanwhile, ELISA and Western blot results showed a decrease in IL-1β, IL-6, TNFα, PTGS2 and VEGFα in tumor tissue of JWYHD groups. The results were also verified in LPS-induced RAW264.7 cells and zebrafish inflammatory models. TUNEL assay and IHC results showed that JWYHD significantly induced apoptosis. Seventy-two major compounds in JWYHD were identified by UPLC-MS/MS and Network pharmacology. It was found that the significant binding affinity of JWYHD to TNFα, PTGS2, EGFR, STAT3, VEGFα and their expressions were inhibited by JWYHD. IHC and Western blot analysis showed that JWYHD could decrease the expression of JAK2/STAT3 pathway. Furthermore, Colivelin could reverse the decrease effect of JWYHD in vitro. CONCLUSION JWYHD exerts a significant anti-tumor effect mainly by inhibiting inflammation, activating immune responses and inducing apoptosis via the JAK2/STAT3 signaling pathway. Our findings provide strong pharmacological evidence for the clinical application of JWYHD in the management of breast cancer.

Abstract
Alzheimer's disease (AD) is the most common neurodegenerative disease characterized by amyloid-β (Aβ) deposition, accompanied by neuroinflammation and memory dysfunction. Houttuyniae Herba (aerial parts of Houttuynia cordata, also known as fish mint; HH), an herbal medicine traditionally used to treat fever, urinary disorders, and pus, is revealed to protect neurons from Aβ toxicity and regulate cholinergic dysfunction in AD models. In this study, we aimed to investigate the effects of HH on excessive accumulation of Aβ followed by neuroinflammation, synaptic degeneration, and memory impairment. Two-month-old 5xFAD transgenic mice were administered HH at 100 mg/kg for 4 months. We observed that HH treatment ameliorated memory impairment and reduced Aβ deposits in the brains of the mice. HH directly inhibited Aβ aggregation in vitro using the Thioflavin T assay and indirectly suppressed the amyloidogenic pathway by increasing alpha-secretase expression in the mice brain. In addition, HH exerted antineuroinflammatory effects by reducing of glial activation and p38 phosphorylation. Moreover, HH treatment increased the expression of synaptophysin, a presynaptic marker protein. Overall, HH alleviates memory impairment in AD by facilitating nonamyloidogenic pathway and inhibiting neuroinflammation. Therefore, we suggest that HH can be a promising herbal drug for patients with AD requiring multifaceted improvement.
