Transgelin-2 in Multiple Myeloma: A New Marker of Renal Impairment? Molecules 2021; 27:molecules27010079. [PMID: 35011306 PMCID: PMC8746652 DOI: 10.3390/molecules27010079] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Revised: 12/16/2021] [Accepted: 12/21/2021] [Indexed: 01/12/2023] Open
Abstract
Transgelin is a 22-kDa protein involved in cytoskeletal organization and expressed in smooth muscle tissue. According to animal studies, it is a potential mediator of kidney injury and fibrosis, and moreover, its role in tumorigenesis is emerging in a variety of cancers. The study included 126 ambulatory patients with multiple myeloma (MM). Serum transgelin-2 concentrations were measured by enzyme-linked immunoassay. We evaluated associations between baseline transgelin and kidney function (serum creatinine, estimated glomerular filtration rate—eGFR, urinary markers of tubular injury: cystatin-C, neutrophil gelatinase associated lipocalin—NGAL monomer, cell cycle arrest biomarkers IGFBP-7 and TIMP-2) and markers of MM burden. Baseline serum transgelin was also evaluated as a predictor of kidney function after a follow-up of 27 months from the start of the study. Significant correlations were detected between serum transgelin-2 and serum creatinine (R = 0.29; p = 0.001) and eGFR (R = −0.25; p = 0.007). Transgelin significantly correlated with serum free light chains lambda (R = 0.18; p = 0.047) and serum periostin (R = −0.22; p = 0.013), after exclusion of smoldering MM patients. Patients with decreasing eGFR had higher transgelin levels (median 106.6 versus 83.9 ng/mL), although the difference was marginally significant (p = 0.05). However, baseline transgelin positively correlated with serum creatinine after the follow-up period (R = 0.37; p < 0.001) and negatively correlated with eGFR after the follow-up period (R = −0.33; p < 0.001). Moreover, higher baseline serum transgelin (beta = −0.11 ± 0.05; p = 0.032) significantly predicted lower eGFR values after the follow-up period, irrespective of baseline eGFR and follow-up duration. Our study shows for the first time that elevated serum transgelin is negatively associated with glomerular filtration in MM and predicts a decline in renal function over long-term follow-up.

Biomedicines 2021; 9:biomedicines9091145. [PMID: 34572331 PMCID: PMC8467952 DOI: 10.3390/biomedicines9091145] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 08/20/2021] [Accepted: 08/24/2021] [Indexed: 12/24/2022] Open
Abstract
Renal cell carcinoma (RCC) represents about 2-3% of all cancers with over 400,000 new cases per year. Sunitinib, a vascular endothelial growth factor tyrosine kinase receptor inhibitor, has been used mainly for first-line treatment of metastatic clear-cell RCC with good or intermediate prognosis. However, about one-third of metastatic RCC patients do not respond to sunitinib, leading to disease progression. Here, we aim to find and characterize proteins associated with poor sunitinib response in a pilot proteomics study. Sixteen RCC tumors from patients responding (8) vs. non-responding (8) to sunitinib 3 months after treatment initiation were analyzed using data-independent acquisition mass spectrometry, together with their adjacent non-cancerous tissues. Proteomics analysis quantified 1996 protein groups (FDR = 0.01) and revealed 27 proteins deregulated between tumors non-responding vs. responding to sunitinib, representing a pattern of deregulated proteins potentially contributing to sunitinib resistance. Gene set enrichment analysis showed an up-regulation of epithelial-to-mesenchymal transition with transgelin as one of the most significantly abundant proteins. Transgelin expression was silenced by CRISPR/Cas9 and RNA interference, and the cells with reduced transgelin level exhibited significantly slower proliferation. Our data indicate that transgelin is an essential protein supporting RCC cell proliferation, which could contribute to intrinsic sunitinib resistance.

Abstract
BACKGROUND Hypertensive nephrosclerosis is one of the most frequent causes of chronic kidney failure. Proteome analysis potentially improves the pathophysiological understanding and diagnostic precision of this disorder. In the present exploratory study, we investigated experimental nephrosclerosis in the two-kidney, one-clip (2K1C) hypertensive rat model. METHODS The renal cortex proteome from juxtamedullary cortex and outer cortex of 2K1C male Wistar-Hannover rats (n = 4) was compared with the sham-operated controls (n = 6), using mass spectrometry-based quantitative proteomics. We combined a high abundant plasma protein depletion strategy with an extended liquid chromatographic gradient to improve peptide and protein identification. Immunohistology was used for independent confirmation of abundance. RESULTS We identified 1724 proteins, of which 1434 were quantified with at least two unique peptides. Comparative proteomics revealed 608 proteins, including the platelet-derived growth factor receptor-β signalling pathway, with different abundances between the non-clipped kidney of hypertensive 2K1C rats and the corresponding kidney of the normotensive controls (P < 0.05, absolute fold change ≥1.5). Among the most significantly altered proteins in the whole cortex were periostin, transgelin, and creatine kinase B-type. Relative abundance of periostin alone allowed clear classification of 2K1C and controls. Enrichment of periostin in 2K1C rats was verified by immunohistology, showing positivity especially around the fibrotic vessels. CONCLUSION The proteome is altered in hypertension-induced kidney damage. We propose periostin, especially in combination with transgelin and creatine kinase B-type, as possible proteomic classifier to distinguish hypertensive nephrosclerosis from the normal tissue. This classifier needs to be further validated with respect to early diagnosis of fibrosis, prognosis, and its potential as a novel molecular target for pharmacological interventions.

Abstract
Cystinosis is an inherited disorder resulting from a mutation in the CTNS gene, causing progressive proximal tubular cell flattening, the so-called swan-neck lesion (SNL), and eventual renal failure. To determine the role of oxidative stress in cystinosis, histologic sections of kidneys from C57BL/6 Ctns(-/-) and wild-type mice were examined by immunohistochemistry and morphometry from 1 wk to 20 mo of age. Additional mice were treated from 1 to 6 mo with vehicle or mitoquinone (MitoQ), an antioxidant targeted to mitochondria. The leading edge of the SNL lost mitochondria and superoxide production, and became surrounded by a thickened tubular basement membrane. Progression of the SNL as determined by staining with lectin from Lotus tetragonolobus accelerated after 3 mo, but was delayed by treatment with MitoQ (38 ± 4% vs. 28 ± 1%, P < 0.01). Through 9 mo, glomeruli had retained renin staining and intact macula densa, whereas SNL expressed transgelin, an actin-binding protein, but neither kidney injury molecule-1 (KIM-1) nor cell death was observed. After 9 mo, clusters of proximal tubules exhibited localized oxidative stress (4-hydroxynonenal binding), expressed KIM-1, and underwent apoptosis, leading to the formation of atubular glomeruli and accumulation of interstitial collagen. We conclude that nephron integrity is initially maintained in the Ctns(-/-) mouse by adaptive flattening of cells of the SNL through loss of mitochondria, upregulation of transgelin, and thickened basement membrane. This adaptation ultimately fails in adulthood, with proximal tubular disruption, formation of atubular glomeruli, and renal failure. Antioxidant treatment targeted to mitochondria delays initiation of the SNL, and may provide therapeutic benefit in children with cystinosis.

Abstract
Fibrosis is a state, in which excess amounts of extracellular matrix are deposited in the tissue. Fibrosis can occur in various organs, including the liver, lung, kidney and heart. The progression of fibrosis involves interstitial hypercellularity, accumulation of extracellular matrix, and atrophy of epithelial structures, resulting in a loss of normal function. Myofibroblasts play a crucial role in the development and progress of fibrosis. When stimulated, myofibroblasts actively synthesize connective tissue components and cause organ fibrosis. As a result, the process and the mechanism of myofibroblast activation represent a target for antifibrotic treatment. As yet, however, an effective treatment has not been developed, and new treatment modalities are expected. Because activation of myofibroblasts is a key event during fibrosis development, there is great interest in identifying and characterizing proteins whose expression is changed after this activation. In this review, fibrosis is outlined and the role of myofibroblasts in this disorder is described. Furthermore, the search for candidate proteins to target for treatment and the prospects of antifibrotic therapy are discussed.

Abstract
Fibrosis is a complex and multifactorial process, affecting the structure and compromising the function of several organs. Among those, renal fibrosis is an important pathological change, eventually leading to renal failure. Proteomic analysis of the renal parenchyma in the well-established rat model of unilateral ureteral obstruction (UUO model) suggested that transgelin was up-regulated during the development of fibrosis. Transgelin up-regulation was confirmed both at the protein and at the mRNA level. It was observed that at early stages of fibrosis transgelin was mainly expressed in the interstitial compartment and, more specifically, in cells surrounding the glomeruli. Subsequently, it was confirmed that transgelin expressing cells were activated fibroblasts, based on their extensive co-expression of α-SMA and their complete lack of co-distribution with markers of other cell types (endothelial, epithelial and cells of the immune system). These periglomerular fibroblasts exhibited staining for transgelin mainly cytoplasmic but occasionally nuclear as well. In addition, transgelin expression in periglomerular fibroblasts was absent in renal fibrosis developed in a hypertensive model, compared to the UUO model. Promoter analysis indicated that there are several conserved motifs for transcription factor binding. Among those, Kruppel-like factor 6 was found to be up-regulated in transgelin positive periglomerular activated fibroblasts, suggesting a possible involvement in the mechanism of transgelin up-regulation. These data strongly suggest that transgelin is up-regulated in the obstructive nephropathy and could be used as a novel marker for renal fibrosis in the future.

Abstract
Colorectal cancer (CRC) is a common malignancy with a high incidence and mortality rate. Recent studies have pointed to deregulation of autophagy as a novel pathogenesis of human malignancy. SM22 is considered as a tumor suppressor. The aim of the present study was to evaluate the correlation of the SM22 expression level with the autophagy activity and the clinical characteristics in human CRC tissues. The expressions of SM22 and p62, a biomarker of autophagy activity, in paired tumor and adjacent non-tumor tissues from 43 patients with colorectal cancer were detected by western blot and immunohistochemical staining, respectively. The results showed that the SM22 level decreased significantly in 81.4% CRC tissues, while the expression of p62 increased in 79.1% cases. There was a negative correlation between p62 and SM22 expressions in colorectal cancer tissues (p=0.004). Similarly, the negative correlation between SM22 and p62 was verified in human CRC cell lines. The data suggest that the autophagy activity decreased in human CRC, which was associated with reduction in SM22 expression. However, the expression of SM22 was not associated with the gender, tumor site and Duke's stage of the patients. In conclusion, our findings suggest that the disruption of SM22 may be involved in tumorigenesis in CRC. The autophagic activity may be suppressed in human CRC, and SM22 may act as a positive regulator in the processes of autophagy.

Abstract
Mesangial cell (MC) migration is essential during glomerular repair and kidney development. The aim of the study was to identify marker/player for glomerular progenitor/reserve cells migrating into the glomerulus after MC injury and during glomerulogenesis in the rat. Experimental mesangial proliferative nephritis was induced in Sprague Dawley rats by intravenous injection of OX-7 antibody. We investigated mRNA expression profiles in isolated glomeruli from on days 0, 1, 2, 3, and 5 after induction of anti-Thy1 nephritis using Affymetrix microarray technology. Using self-organizing maps, transgelin was identified as a new marker for repopulating glomerular cells. Expression of transgelin during anti-Thy1 nephritis was investigated by northern blot, real-time PCR, western blot, and immunohistochemistry. Migration and proliferation assays using isolated MCs after transgelin knockdown by siRNA were performed to investigate the potential role of transgelin during glomerular repopulation. Transgelin mRNA was not detected in healthy glomeruli. It was strongly upregulated during the repopulation process starting on day 1, continued to be increased until day 5 and disappeared on day 7. Transgelin was specifically expressed at the edge of the migratory front during glomerular repopulation as indicated by transgelin/OX-7 double staining. Transgelin expression was similar in migrating vs non-migrating MCs in vitro. Blocking of transgelin expression by siRNA treatment resulted in inhibition of MC migration and proliferation. Transgelin was also expressed in MCs during glomerulogenesis and in biopsies from patients with IgA nephritis. In conclusion, transgelin in the kidney is upregulated in repopulating MCs in vivo and supports their migratory and proliferative repair response after injury.
