Association of ITGAX and ITGAM gene polymorphisms with susceptibility to IgA nephropathy. J Hum Genet 2019; 64:927-935. [PMID: 31227791 DOI: 10.1038/s10038-019-0632-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2019] [Revised: 04/25/2019] [Accepted: 06/06/2019] [Indexed: 02/02/2023]
Abstract
Previous genome-wide association studies have discovered significant association at ITGAX-ITGAM on 16p11.2 for IgA nephropathy (IgAN). In this study, we performed a two-stage association study that enrolled 1700 IgAN cases and 2400 controls to further investigate the relationship of ITGAX and ITGAM gene polymorphisms with IgAN. Seven single-nucleotide polymorphisms (SNPs) were selected for genotyping in 1000 IgAN cases and 1000 healthy controls in the discovery stage, and the significant SNP was further validated in additional 700 IgAN cases and 1400 healthy controls. We found that four SNPs (rs11150619, rs11150614, rs7190997, and rs4597342) showed potential associations with IgAN susceptibility in the discovery stage, but only SNP rs11150619 was further genotyped in the validation stage after multiple testing. The results indicated that rs11150619 was significantly associated with IgAN in the combined samples (OR = 0.81, 95%CI = 0.71-0.91, and dominant P = 6.68 × 10-4). Moreover, patients with TT genotype of rs11150619 exhibited increased estimated glomerular filtration rate levels and a reduced proportion of global sclerosis compared with those with TC and CC genotypes. Our results suggested that ITGAX and ITGAM gene polymorphisms were associated with IgAN in a Chinese Han population, and the rs11150619-T allele showed a potential protective role for IgAN.

Oldenlandia diffusa suppresses metastatic potential through inhibiting matrix metalloproteinase-9 and intercellular adhesion molecule-1 expression via p38 and ERK1/2 MAPK pathways and induces apoptosis in human breast cancer MCF-7 cells. JOURNAL OF ETHNOPHARMACOLOGY 2017; 195:309-317. [PMID: 27876502 DOI: 10.1016/j.jep.2016.11.036] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2016] [Revised: 11/17/2016] [Accepted: 11/19/2016] [Indexed: 06/06/2023]
Abstract
ETHNOPHARMACOLOGY RELEVANCE Oldenlandia diffusa (OD) has long been known as an apoptotic inducer in breast tumors in ethnomedicine. AIM OF THE STUDY To scientifically confirm the anti-breast cancer effects of water, methanol (MeOH) and butanol (BuOH) extracts of O. diffusa on cell apoptosis, matrix metalloproteinases (MMPs), intercellular adhesion molecule (ICAM)-1 and intracellular signaling in MCF-7 breast cancer cells. MATERIALS AND METHODS MeOH extracts (MOD) and BuOH extracts (BOD) were prepared and examined for their ability to inhibit phorbol myristate acetate (PMA)-induced matrix metalloproteinase (MMP)-9 and intercellular adhesion molecule (ICAM)-1 expressions in MCF-7 human breast cancer cells. Additionally, transwell migration, invasion and transcriptional activity were assessed. Results of immunofluorescence confocal microscopy for translocation of NF-κB and p-ERK and p-p38 were also checked. Finally, apoptotic signals including processed caspase-8, caspase-7, poly ADP-ribose polymerase, Bax and Bcl-2 were examined. RESULTS MOD and BOD specifically inhibited PMA-induced MMP-9 expression as well as invasive and migration potential via ICAM-1. The inhibitory activity was also based on the suppressed transcriptional activity in MCF-7 breast cancer cells. Results of immunofluorescence confocal microscopy showed that translocation of NF-κB decreased upon BOD and MOD treatments, with a decreased level of p-ERK and p-p38 phosphorylation. In addition, treatment of MCF-7 cells with MOD and BOD activated apoptosis-linked proteins including enzymatically active forms of processed caspase-8, caspase-7 and poly ADP-ribose polymerase, together with increased expression of mitochondrial apoptotic protein, Bax and decreased expression of Bcl-2. CONCLUSION The results indicate that OD as an anti-metastatic agent suppresses the metastatic response by targeting p-ERK, p-38 and NF-κB, thus reducing the invasion capacity of MCF-7 breast cancer cells through inhibition of MMP-9 and ICAM-1 expression and plays an important role in the regulation of breast cancer cell apoptosis.

Abstract
Imbalance of matrix metalloproteinases and tissue inhibitors of metalloproteinases (MMPs/TIMPs) takes part in age-related renal fibrosis; so does molecular inflammation. As several inflammatory mediators including intercellular adhesion molecule-1 (ICAM-1) are substrates of MMPs, we speculated that TIMP-1 might affect ICAM-1 through MMPs and subsequently promote age-related renal fibrosis. Then, we observed changes of kidney in human TIMP-1 transgenic mice and wild-type mice of different ages. It was found that the expressions and activities of gelatinases were downregulated; the expressions of ICAM-1, collagen III, collagen IV, and transforming growth factor (TGF)-beta1 were upregulated; and the number of infiltrating macrophages was increased in kidneys of 24-month-old TIMP-1 transgenic mice with high expressions of TIMP-1, compared with wild-type mice. Our results indicated that TIMP-1 could promote age-related renal fibrosis, which was partly attributed to enhancing inflammation through upregulation of ICAM-1.

Abstract
Costimulatory and adhesion molecules are known to play a major role in the pathogenesis of systemic lupus erythematosus. Since fish oil and calorie restriction have been reported to attenuate the development of disease in lupus prone (NZBxNZW)F1 mice, the objective of this study was to assess the expression of these key inflammatory molecules in these mice fed diets differing in n-6 and n-3 fatty acid content and fed either food restricted or ad libitum. Age-associated increases in the expression of CD28, ICAM-1, and PGP-1 molecules that are involved in the recruitment of inflamed lymphocytes into the kidney were attenuated in mice restricted in food intake. The increase in costimulatory (CD80 and CD86) and adhesion (ICAM-1, PGP-1, LFA-1, and Mac-1) in peripheral blood mononuclear cells was also attenuated by food restriction and to a lesser extent by fish oil alone. Interestingly, amelioration of lupus (laminin expression and proteinuria) correlated with the above beneficial effects and could be seen even in 24-month-old mice. In summary, food restriction and fish oil delay the onset of lupus disease and increase life span in B/W mice by prolonging the maintenance of a youthful immune phenotype.

Abstract
BACKGROUND The aim of this study was to determine the significance of the renal expression of ICAM-1 in IgA nephropathy (IgAN). PATIENTS AND METHOD First, we identified ICAM-1 (CD54) expression in tubular epithelial cells and interstitial leucocytes in renal biopsies from 45 patients with IgAN and 29 patients with non-glomerulonephritis nephropathy (non-GN). We then analysed the relationship between this expression and both histological and clinical data at the time of renal biopsy and after 2.4 (2) (X [SD]) years in IgAN, and 1.8 (1.5) years in non-GN. RESULTS In IgAN, tubular ICAM-1 positive staining was seen in 25 (55%) biopsies; it was associated with extracapillary proliferation, glomerulosclerosis involving less than 50% of glomerular area, interstitial cell infiltration and tubular atrophy. ICAM-1 positive interstitial leucocytes were 234 (307)/mm2; this expression correlated with glomerulosclerosis, tubular atrophy, interstitial fibrosis and serum creatinine (Cr) level. In patients with 50% increase in Cr level, ICAM-1 positive interstitial leucocytes were 516 (360)/mm2 as compared with 66 (87.8)/mm2 (U = 16; p < 0.005) in patients with stable Cr. In non-GN, tubular ICAM-1 expression was observed in 7 (24%) biopsies. CONCLUSIONS Tubular and Interstitial expression of ICAM-1 can be a marker of tubulointerstitial damage in IgAN. Interstitial ICAM-1, rather than tubular ICAM-1, may predict the progression of this disease.

Abstract
Complement activation plays a critical role in the pathogenesis of many forms of glomerulonephritis. Complement activation leads to tissue injury through various mechanisms including the generation of chemotactic factors and activation of the resident glomerular cells following C5b-9 insertion. Recent advances have disclosed the mechanisms of regulation of complement activation by discovery of a number of complement regulatory proteins. Decay accelerating factor (DAF), membrane cofactor protein (MCP), and complement receptor type 1 (CR1) act by inactivating C3/C5 convertase. They belong to the gene superfamily known as the regulators of complement activation (RCA), and share a common structural motif called a short consensus repeat (SCR). In contrast, CD59 works by inhibiting formation of C5b-9. The glomerulus is particularly well endowed with these membrane-bound complement regulatory proteins. DAF, MCP, and CD59 are ubiquitously expressed by all three resident glomerular cells, while CR1 is localized exclusively in podocytes. Expression of complement regulatory proteins can be changed by many factors including complement attack itself, and their expression levels are affected in various glomerular disorders. Studies utilizing cultured glomerular cells and animal models of glomerular diseases suggest important protective roles of complement regulatory proteins against immune-mediated renal injury. Recent progress in molecular biological techniques has made new therapeutic strategy feasible. Systemic administration of soluble recombinant complement regulatory proteins and local overexpression of complement regulatory proteins are promising therapeutic approaches.

Abstract
The expression of the intercellular adhesion molecule-1 (ICAM-1), infiltrating cells positive for its ligand leucocyte adhesion molecule-1(LFA-1), and the markers of total leucocytes (CD45RB), T cells (CD45RO), and monocytes/macrophages (CD68) were examined by an indirect immunoperoxidase method on renal biopsy specimens from 20 patients with mesangial proliferative glomerulonephritis-IgA negative (MesProGN) and 20 with IgA nephropathy (IgAN). Histologically, normal portions of the kidney tissue (n = 15) obtained from patients with renal trauma or renal tumours were used as controls. The expression of ICAM-1 was evident and extended in mesangium, on endothelial cells of peritubular capillaries, interstitial cells, several infiltrating immune cells and on tubular epithelial cells, particularly on atrophic tubuli in renal biopsies of MesProGN and IgAN. In both types of glomerulopathies a significant increase in the number of glomerular and interstitial LFA-1-positive cells correlated positively with the expression of ICAM-1. The number of glomerular and interstitial LFA-1-positive cells correlated positively with the number of monocytes/macrophages in glomeruli and interstitium. The strong correlation between expression of ICAM-1 and LFA-1 and between LFA-1-positive cells and immune cells makes these adhesion molecules useful markers of activity and suggest that they are involved in recruitment of leucocytes in the studied types of proliferative glomerulopathies.

Abstract
The expression of two adhesion molecules, ICAM1 (CD54) and ICAM3 (CD50), infiltrating cells positive for their ligand, LFA1 (CD11a), and the markers of total leukocytes (CD45), T cells (CD3), granulocytes/monocytes (CD15), and macrophages (CD68) in renal interstitium were examined by an indirect immunoperoxidase method. The study was longitudinally performed on repeat renal biopsy specimens from 69 patients with two different proliferative glomerulonephritides: 43 with IgA nephropathy (IgAN) and 26 with membranoproliferative glomerulonephritis (MPGN). Interstitial ICAM1 (iICAM1) was mainly expressed on endothelium of peritubular venules and sometimes on tubular epithelium, and interstitial ICAM3 (iICAM3) on infiltrating immune cells. In IgAN, iICAM1 was significantly correlated with glomerular infiltration of LFA1+ cells (gLFA1) and CD68+ cells (gCD68) (r = 0.478/0.500; P < 0.0001) as well as CD3+ cells (gCD3) (r = 0.402; P < 0.002). In MPGN, iICAM1 was significantly correlated only with gCD68 (r = 0.382; P < 0.05). In both diseases, iICAM1 and iICAM3 were significantly correlated with interstitial infiltration of LFA1+ cells (iLFA1) and CD68+ cells (iCD68) (r = 0.616 to 0.815; P < 0.0001) and with interstitial infiltration of CD3+ cells (iCD3) (r = 0.474 to 0.816; P < 0.01). The iICAM3 was also significantly correlated with interstitial CD45+ cells (iCD45) (r = 0.672 in IgAN and 0.769 in MPGN; P < 0.00001). Interstitial infiltration of these immune cells was significantly correlated with the histologic parameters indicating renal injury, such as the index of glomerular lesion and the percent interstitial volume (r = 0.410 to 692; P < 0.05). Longitudinal analysis revealed that the parameters described above showed corresponding change with each other at the follow-up biopsy. These findings suggest that the glomeruler infiltration of T cells and macrophages influences the ICAM1/ICAM3 expression of the interstitial cells, especially In IgAN, and that ICAM1/LFA1 and ICAM3/LFA1 interactions contribute to the persistent infiltration of the interstitium by immune cells in both diseases.

Abstract
Marked intraglomerular infiltration of leukocytes is observed in membranoproliferative glomerulonephritis (MPGN). We recently demonstrated that this leukocyte infiltration develops partly through macrophage-1 (Mac-1)-positive cells and glomerular C3c deposits (Clin Exp Immunol 100:269-276, 1995). To further investigate the mediation of adhesion molecules in the leukocyte accumulation, we immunohistochemically examined the expression of intraglomerular leukocyte integrins and their ligands as well as surface markers for granulocytes/monocytes (CD15) and macrophages (CD68) in 26 patients with MPGN type I who had undergone repeated biopsies. These patients were divided into two groups. Group A included the patients who showed both normo-complementemia and urinary protein excretion less than 1 g/d at the follow-up biopsy (recovery group: n = 14). Group B (persistent group: n = 12) included the patients other than those in group A. At the initial biopsy, there was no difference in the degree of glomerular C3c deposition, glomerular intercellular adhesion molecule (ICAM)-1 expression, or the numbers of cells bearing leukocyte function-associated antigen-1 (LFA-1), Mac-1, and ICAM-3 between the two groups. At the follow-up biopsy, the degree of glomerular C3c deposition, and the numbers of cells bearing LFA-1, Mac-1, and ICAM-3, were significantly decreased only in group A (P < 0.01, P < 0.001, P < 0.001, and P < 0.01, respectively). No chronological change in ICAM-1 expression was observed in either group. Group B showed a chronological increase in the severity of glomerular injury and serum creatinine level, associated with persistent heavy proteinuria. Neither LFA-1- nor Mac-1-positive cells were positively correlated with ICAM-1 expression. Most of Mac-1-positive cells were CD15-positive cells (granulocytes/monocytes), and a considerable number of Mac-1-positive cells concurrently expressed ICAM-3. In contrast, most LFA-1-positive cells were considered to be CD68-positive cells (macrophages). The number of cells bearing LFA-1 was positively correlated with that of cells bearing ICAM-3 (P < 0.00001). These results suggest that the glomerular leukocytes, infiltrating through Mac-1/complement interaction, express ICAM-3 by themselves, and that LFA-1/ICAM-3 interaction might participate in the glomerular aggregation of leukocytes in MPGN type I. In this study, we could not conclude that LFA-1/ICAM-1 or Mac-1/ICAM-1 interaction was involved in the leukocyte accumulation in this disease.
