PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 122:155144. [PMID: 37925889 DOI: 10.1016/j.phymed.2023.155144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 09/23/2023] [Accepted: 10/12/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND Colorectal cancer (CRC) metastasis is a complicated process that not only involves tumor cells but also the effects of M2 type tumor-associated macrophages, a key component of the tumor microenvironment (TME), act a crucial role in cancer metastasis. Macelignan, an orally active lignan isolated from Myristica fragrans, possesses various beneficial biological activities, including anti-cancer effects, but its effect on macrophage polarization in the TME remains unknown. PURPOSE To evaluate the inhibitory potency and prospective mechanism of macelignan on M2 polarization of macrophages and CRC metastasis. METHODS The polarization and specific mechanism of M1 and M2 macrophage regulated by macelignan were determined by western blot, flow cytometry, immunofluorescence and network pharmacology. In vitro and in vivo function assays were performed to investigate the roles of macelignan in CRC metastasis. RESULTS Macelignan efficiently inhibited IL-4/13-induced polarization of M2 macrophages by suppressing the PI3K/AKT pathway in a reactive oxygen species (ROS)-dependent manner. The proportion of CD206+ M2 macrophages was elevated in patients with CRC liver metastasis. Furthermore, macelignan inhibited M2 macrophage-mediated metastasis of CRC cells in vitro and in vivo. Mechanistically, macelignan reduced secretion of IL-1β from M2 macrophages, which in turn blocked NF-κB p65 nuclear translocation and inhibited metastasis. CONCLUSION Macelignan suppressed macrophage M2 polarization via ROS-mediated PI3K/AKT signaling pathway, thus preventing IL-1β/NF-κB-dependent CRC metastasis. In the present study, we reveal a previously unrecognized mechanism of macelignan in the prevention of CRC metastasis and demonstrate its effectively and safely therapeutic potential in CRC treatment.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 317:116812. [PMID: 37343651 DOI: 10.1016/j.jep.2023.116812] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 06/02/2023] [Accepted: 06/16/2023] [Indexed: 06/23/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Mongolian medicine Nuangong Qiwei Pill (NGQW) is a folk prescription with a long history of use by the Mongolian people. NGQW comprises seven Mongolian medicines, which have the effects of regulating and nourishing blood, warming the uterus, dispelling cold and relieving pain. For a long time, it has been used as a good remedy for gynecological diseases, with remarkable curative effects, favored by the majority of patients and recommended by doctors. Polycystic ovary syndrome (PCOS) is a common gynecological endocrine disorder that can lead to menstrual disorders or infertility. In the gynecological classification of Mongolian medicine, polycystic ovary syndrome has not been distinguished in detail, and the mechanism of NGQW in the treatment of polycystic ovary syndrome has not been scientifically studied and standardized. AIM OF THE STUDY The aim of this study was to clarify the mechanism of action of NGQW and macelignan in the treatment of PCOS and to provide a reference for the clinical application of these drugs. MATERIALS AND METHODS The effect of intragastric administration of NGQW and macelignan on PCOS model mice was observed. The mental status of mice was examined behaviorally, and serum hormone levels and oxidative stress parameters were measured by ELISA. Giemsa staining was used to detect the reproductive cycle, and HE staining was used to observe the ovarian status. Immunofluorescence staining was performed to observe the proliferation and apoptosis of ovarian granulosa cells. qRT‒PCR was conducted to measure the expression of IL-6, BAX, BCL-2, and estrogen synthesis-related genes in ovarian tissue and particle cells. RESULTS In the dehydroepiandrosterone (DHEA)-induced PCOS model mice, both NGQW and macelignan improved the estrous cycle; increased the estradiol (E2) content; lowered testosterone (T), progesterone (P) and luteinizing hormone (LH) levels; reduced the number of polycystic follicles; promoted granulosa cell proliferation; reduced granulosa cell apoptosis; and alleviated depression and anxiety. In addition, Nuangong Qiwei Pill and macelignan reduced the mRNA levels of the ovarian inflammatory factor IL-6; improved the disordered levels of the antioxidant indicators GSH, MDA, and SOD; and activated the TGF-β3 signaling pathway to increase the transcription of Cyp19a1, which increases estrogen secretion. CONCLUSION NGQW and macelignan can treat PCOS through the TGF-β3/Smad/Cyp19a1 signaling pathway to regulate the secretion ability of ovarian granulosa cells. Our research justifies the traditional use of NGQW to treat PCOS and enriches the scope of action of macelignan.

Abstract
Alzheimer's Disease (AD) is a global public health priority characterized by high mortality rates in adults and an increasing prevalence in aging populations worldwide. Despite significant advancements in comprehending the pathogenesis of AD since its initial report in 1907, there remains a lack of effective curative or preventive measures for the disease. In recent years, natural compounds sourced from diverse origins have garnered considerable attention as potential therapeutic agents for AD, owing to their anti-inflammatory, antioxidant, and neuroprotective properties. This review aims to consolidate the therapeutic effects of natural compounds on AD, specifically targeting the reduction of β-amyloid (Aβ) overproduction, anti-apoptosis, autophagy, neuroinflammation, oxidative stress, endoplasmic reticulum (ER) stress, and mitochondrial dysfunction. Notably, the identified compounds exhibiting these effects predominantly originate from plants. This review provides valuable insights into the potential of natural compounds as a reservoir of novel therapeutic agents for AD, thereby stimulating further research and contributing to the development of efficacious treatments for this devastating disease.

Abstract
Many neurodegenerative diseases display both neuroinflammation and impaired neuron production in hippocampus. Although immunotherapeutic strategies indicate a promising avenue for combating neuroinflammation-induced diseases, directly targeting microglia, principle immune cells of CNS for such therapeutic purposes might be problematic due to invasive procedures. Instructing monocytes/macrophages from the periphery can be a less invasive and advantageous strategy compared to reaching microglia. But interplay between CNS neurons and macrophages even under normal conditions is poorly understood. To explore the experimental platform of how CNS derived neuronal cells respond to overall soluble factors of a non-CNS derived immune cell type, we introduced the conditioned media (CM) of unstimulated, and lipopolysaccharide stimulated RAW264.7 mouse macrophages to immortalized HT-22 mouse hippocampal cells during and after they were exposed to neuronal differentiation media. First, we recorded the cell viability of HT-22 cell study groups by using a real time cell analyzer. Then, we assessed the immunocytochemical expression of CR and CB proteins and mRNA levels of Ascl1, Bdnf, CB, Grn, Nrf2 and Rac1 genes via semi quantitative image analysis and q-RT-PCR among the different groups of HT-22 cells. Real time cell monitoring provided a solid physiological evidence regarding how various cell culture treatments affected the cell viability of HT-22 cells over time. Our further findings suggested that culturing HT-22 cells with unstimulated CM of macrophages markedly increased the immunocytochemical expression of CR and mRNA expression of Ascl1, Bdnf, CB and Grn genes, while the latter media resulted in decreases of those expressions. Overall, our results imply that HT-22 cells are meaningfully responsive to the secretome of RAW264.7 macrophages and using the interaction of macrophage with CNS derived neuronal cells is an instructive platform for deciphering the molecular mechanisms of cellular communication between immune system cells and neurons.

Abstract
Depression is a severe neurological disorder highly associated with chronic mental stress stimulation, which involves chronic inflammation and microglial activation in the central nervous system (CNS). Salidroside (SLDS) has been reported to exhibit anti-neuroinflammatory and protective properties on neurological diseases. However, the mechanism underlying the effect of SLDS on depressive symptoms has not been well elaborated. In the present study, the effects of SLDS on depressive behaviors and microglia activation in mice CNS were investigated. Behavioral tests, including Forced swimming test (FST), Open field test (OFT) and Morris water maze (MWM) revealed that SLDS treatment attenuated the depressive behaviors in stress mice. SLDS treatment significantly reduced the microglial immunoreactivity for both Iba-1 and CD68, characteristic of deleterious M1 phenotype in hippocampus of stress mice. Additionally, SLDS inhibited microglial activation involving the suppression of ERK1/2, P38 MAPK and p65 NF-κB activation and thus reduced the expression and release of neuroinflammatory cytokines in stress mice as well as in lipopolysaccharide (LPS)-induced primary microglia. Also, SLDS changed microglial morphology, attachment and reduced the phagocytic ability in LPS-induced primary microglia. The results demonstrated that SLDS treatment could improve the depressive symptoms caused by unpredictable chronic stress, indicating a potential therapeutic application of SLDS in depression treatment by interfering microglia-mediated neuroinflammation.

Abstract
Anwulignan is a monomer compound derived from Schisandra sphenanthera lignans. It has been reported to possess a spectrum of pharmacological activities, including anti-bacterial, anti-inflammatory, anticancer and hepatoprotective properties. However, its anticancer capacity and molecular mechanism(s) against non-small cell lung cancer (NSCLC) have not been fully elucidated. Anwulignan significantly inhibited cell growth and increased G1-phase cell cycle arrest in NSCLC cells. Anwulignan strongly attenuates the JAK1/STAT3 signalling pathway by directly targeting JAK1 protein kinase activity in vitro. The anticancer activity by Anwulignan is dependent upon the JAK1 protein expression. Remarkably, Anwulignan strongly inhibited tumour growth in vivo. In conclusion, Anwulignan is a novel JAK1 inhibitor that may have therapeutic implications for NSCLC management.
