Fangji Huangqi Decoction alleviates rheumatoid arthritis through regulating HIF-1α mediated the angiogenesis and the balance between autophagy and apoptosis. JOURNAL OF ETHNOPHARMACOLOGY 2024; 329:118061. [PMID: 38614265 DOI: 10.1016/j.jep.2024.118061] [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: 01/23/2024] [Revised: 02/29/2024] [Accepted: 03/13/2024] [Indexed: 04/15/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fangji Huangqi Decoction (FHD) is frequently prescribed for the clinical treatment of wind-cold and wind-dampness pathogenic superficial deficiency syndrome. It also has a notable curative effect on rheumatoid arthritis (RA). AIM OF THE STUDY The study aimed to explore the possible mechanism of FHD against RA and provided a theoretical basis for alternative therapies for RA. MATERIALS AND METHODS We used UPLC-Q-TOF-MS to analysis the ingredients and absorbed blood components of FHD. At the same time, the collagen-induced arthritis (CIA) rat model was established to estimate the therapeutic effects on FHD by considering body weight, arthritis score, paw swelling, autonomous movement ability, and synovial microvessel counts. Subsequently, immunofluorescence, immunohistochemistry, and Western blot were employed to detect the anti-angiogenic capacity of FHD in vivo, as well as the levels of apoptosis and autophagy in the synovial tissue. In addition, flow cytometry and Western blot were used to assess the effects of FHD on apoptosis and autophagy in MH7A cells. The effects of FHD on the proliferation and migration of MH7A cells were measured by CCK8 assay, cell migration and, invasion experiments. Finally, a tube formation assay was performed to evaluate the angiogenic capacity of FHD in co-cultures of MH7A cells and HUVEC cells. RESULTS Through testing of FHD's original formula, a total of 26 active ingredients have been identified, with 17 of them being absorbed into the bloodstream. FHD significantly improved the pathological symptoms and synovial hyperplasia of CIA rats. FHD could suppress the expression of HIF-1α, promote apoptosis in CIA rat synovial tissue, and suppress autophagy and angiogenesis. In vitro experiments showed that serum containing FHD inhibited the proliferation, migration, and invasion of MH7A cells, and also suppressed the expression of autophagy-related proteins while promoting apoptosis. FHD markedly repressed the expression of HIF-1α protein in TNF-α-stimulated MH7A cells and inhibited the tube formation capacity induced by MH7A cells in HUVEC cells. CONCLUSIONS The study had proven that FHD played an excellent anti-RA role, which may be attributed to its potential mechanism of regulating the balance between autophagy and apoptosis in RA FLS by suppressing the HIF-1α, thus contributing to its anti-angiogenic activities.

Abstract
A minimal diffusion barrier is key to the pulmonary gas exchange. In alveolar capillary dysplasia (ACD), a rare genetically driven disease of early infancy, this crucial fibrovascular interface is compromised while the underlying pathophysiology is insufficiently understood. Recent in-depth analyses of vascular alterations in adult lung disease encouraged researchers to extend these studies to ACD and compare the changes of the microvasculature. Lung tissue samples of children with ACD (n = 12), adults with non-specific interstitial pneumonia (n = 12), and controls (n = 20) were studied using transmission electron microscopy, single-gene sequencing, immunostaining, exome sequencing, and broad transcriptome profiling. In ACD, pulmonary capillary basement membranes were hypertrophied, thickened, and multilamellated. Transcriptome profiling revealed increased CDH5, COL4A1, COL15A1, PTK2B, and FN1 and decreased VIT expression, confirmed by immunohistochemistry. In contrast, non-specific interstitial pneumonia samples showed a regular basement membrane architecture with preserved VIT expression but also increased COL15A1+ vessels. This study provides insight into the ultrastructure and pathophysiology of ACD. The lack of normally developed lung capillaries appeared to cause a replacement by COL15A1+ vessels, a mechanism recently described in interstitial lung disease. The VIT loss and FN1 overexpression might contribute to the unique appearance of basement membranes in ACD. Future studies are needed to explore the therapeutic potential of down-regulating the expression of FN1 and balancing VIT deficiency.

Abstract
OBJECTIVE To investigate the molecular mechanism of hypoxia-induced rheumatoid arthritis synovial fibroblast (RASF) activation via Notch-1 and Notch-3 signaling, and to evaluate its potential as a therapeutic target. METHODS Expression of Notch-1 intracellular domain (N1ICD), N3ICD, and hypoxia-inducible factor 1α (HIF-1α) was assessed by immunhistology in synovial tissue from patients with RA. RASFs were cultured under hypoxic conditions and normoxic conditions with or without small interfering RNAs (siRNAs), and N1ICD and N3ICD were overexpressed under normoxic conditions. Rats with collagen-induced arthritis (CIA) were administered LY411575 (inhibitor of N1ICD and N3ICD) for 15 days and 28 days, and its therapeutic efficacy was assessed by histologic and radiologic evaluation of the rat synovial tissue, and by analysis of inflammatory cytokine production in the serum of rats. RESULTS N1ICD, N3ICD, and HIF-1α were expressed abundantly in the synovial tissue of RA patients. HIF-1α was shown to directly regulate the expression of Notch-1 and Notch-3 genes under hypoxic conditions. Moreover, hypoxia-induced N1ICD and N3ICD expression in RASFs was blocked by HIF-1α siRNA. Notch-1 siRNA and Notch-3 siRNA inhibited hypoxia-induced RASF invasion and angiogenesis in vitro, whereas overexpression of N1ICD and N3ICD promoted these processes. In addition, Notch-1 was shown to regulate RASF migration and epithelial-mesenchymal transition under hypoxic conditions, whereas Notch-3 was shown to regulate the processes of anti-apoptosis and autophagy. Furthermore, in vivo studies in rats with CIA showed that the N1ICD and N3ICD inhibitor LY411575 had a therapeutic effect in terms of ameliorating the symptoms and severity of the disease. CONCLUSION This study identified a functional link between HIF-1α, Notch-1, and Notch-3 signaling in regulating activation of RASFs and the processes involved in the pathogenesis of RA.

Abstract
Rheumatoid arthritis is a complex disease of unknown origin. In consequence of some immunological reactions, proliferative invading synovial tissue leads to destruction of normal joint architecture. The aim of this study was to investigate qualitative changes in extracellular matrix distribution of proliferating rheumatoid synovium and their cellular origin. Synovial tissues from 57 clinically indicated arthrotomies were investigated with immunofluorescence, using specific antibodies against extracellular matrix proteins in tissue slides and cultured cells, which were also studied for collagen biosynthesis. Results indicated that synovial fibroblast-like cells synthesize and secrete basement membrane proteins laminin and collagen type IV as e.g. endothelial cells or organogenic fibroblasts. Laminin and collagen type IV were specifically demonstrated pericellularly in the hyperplastic lining layer of active rheumatoid synovitis. These findings are discussed with respect to the possible implication of altered cell-matrix interactions in rheumatoid synovial proliferation.

Abstract
Pathologic changes in the basement membrane (BM) of postcapillary venules (PCV) and capillaries in rheumatoid arthritis (RA) synovium were studied by immunoelectron microscopy, using a monoclonal antibody against human type IV collagen, C(IV)22, and by electron microscopic morphometric analysis. The sublining region of RA synovium was classified into lymphocyte-rich areas, transitional areas, and interstitial areas, according to their pattern of cellular infiltration. In lymphocyte-rich areas, the BM of the PCV and capillaries were minimally thickened; disruption of the lamina densa was seldom seen. Transitional areas, which contained macrophages, lymphocytes, and plasma cells, had numerous PCV and capillaries. The BM was markedly thickened and partially multilamellated, and there were many disruptions in the lamina densa. The BM contained degenerated endothelial cells and cell debris. On immunostaining of this BM with monoclonal antibody C(IV)22, type IV collagen stained heavily, mainly in the disrupted lamina densa; this indicates that the thickening was, at least in part, the result of an increase in BM collagen. In uninfiltrated interstitial areas, BM were moderately thickened and multilamellated, and showed few disruptions of the lamina densa; there were similar increases in type IV collagen, but cell debris was seldom observed. Measurement of the BM width, the ratio of BM width to vessel diameter, and the fraction of vascular cross-sectional area occupied by BM demonstrated that the thickness of the BM of both PCV and capillaries was greatest in transitional areas and was smallest in lymphocyte-rich areas (P less than 0.01). Since macrophages and macrophage-derived factors have been found to promote synthesis of BM collagen type IV, and since transitional and interstitial areas are rich in macrophages and histiocytes, respectively, it is suggested that these mononuclear cells and the factors secreted by them play a significant role in the thickening of the BM of PCV and capillaries in RA synovitis.

Abstract
The distribution of fibronectin in rheumatoid arthritis (RA) synovium has been investigated by light and electron microscopic immunohistochemistry using an antihuman fibronectin antibody. Heavy accumulation of fibronectin was observed in the lining layer and the areas of proliferation of fibroblasts. Rough endoplasmic reticulum (RER) and peripheral vesicles of proliferated type B lining cells and fibroblasts contained large amounts of fibronectin. Thus these cells seem to participate actively in the local synthesis and secretion of this glycoprotein. Type A lining cells and migrated mononuclear phagocytes contained many phagolysosomes in some of which dense accumulation of fibronectin was observed. Some of the materials in the phagolysosomes, with dense accumulation of fibronectin, resembled the fibrinous material-fibronectin complexes frequently seen in the pericellular spaces. Accordingly fibronectin seems to play a role in the clearance of fibrinous materials by these phagocytes. The proliferated capillaries and small vessels possessed multilamellated basement membranes with heavy accumulation of fibronectin. However, RER or Golgi apparatus of the endothelial cells contained no detectable amounts of fibronectin. This indicates that these cells do not actively participate in the synthesis of fibronectin and that the majority of this glycoprotein in the basement membranes originates in fibronectin from blood vessel exudate. Fibrinous material-fibronectin complexes were frequently seen on the endothelial cell surfaces. Circulating platelets and mononuclear cells occasionally came in contact with these complexes, suggesting an association of fibronectin with the formation and clearance of thrombi in the vascular lumina at the inflammatory sites of RA synovium.
