This study aimed to examine IL-6 promoter polymorphisms at positions -174G/C, -572G/C, -597A/G, and -634C/G and their associations to osteoporosis status in Javanese postmenopausal women. A cross-sectional study was conducted at an elderly integrated service post in Sidoarjo, Indonesia. Among 699 screened individuals, 66 postmenopausal women fulfilled the inclusion and exclusion criteria. Bone mineral density was assessed using dual-energy X-ray absorptiometry (DXA), and osteoporosis status was defined based on T-score values. IL-6 promoter polymorphisms were genotyped by sequencing PCR-amplified promoter regions. IL-6 mRNA expression was assessed using RT-PCR followed by densitometric analysis, and serum IL-6 concentrations were determined using enzyme-linked immunosorbent assay. Our study showed that osteoporosis and osteopenia were predominant (28.8% and 57.6%, respectively), and 13.6% of subjects had normal BMD. The IL-6 promoter variant genotypes and frequencies were as follows: at -174 GG (0.924), CC (0.045), and GC (0.030); at -572 GC (0.424), CC (0.406), and GG (0.167); at -597 GG (0.924) and GA (0.0758) GA (0.076); and at -634 CC (1). The IL-6 mRNA and protein level (median 6.06, IQR 5.0398 pg/mL) were not statistically different among individuals with different genotypes and with normal, osteopenia, or osteoporosis status. Ordinal regression showed that IL-6 promoter polymorphisms were not significantly associated with osteoporosis status. The polymorphisms of the IL-6 promoter were detected in Javanese postmenopausal women; however, such polymorphisms did not correlate with IL-6 mRNA and protein levels nor osteoporosis status.

The purpose of this work is to propose and articulate a mechanistic and therapeutic framework in which mitochondrial stress is deliberately harnessed to convert immunologically \"cold\" breast tumors into \"hot,\" T cell-inflamed, immunotherapy-responsive lesions. This review synthesizes emerging evidence positioning mitochondrial stress as a strategic lever to transform these immune-excluded tumors into inflamed, therapy-responsive lesions. We examine how mitochondrial dysfunction triggers cytosolic release of mitochondrial DNA (mtDNA), a potent damage-associated molecular pattern that activates the cGAS-STING pathway, initiating type I interferon responses and secretion of T-cell-recruiting chemokines such as CCL5 and CXCL10. This axis functions as a \"double-edged sword\"-while acute activation converts \"cold\" tumors into \"hot\" immune-responsive states, chronic engagement drives immunosuppressive cytokine networks and therapeutic resistance, with outcomes varying across breast cancer subtypes. We explore six combination therapeutic strategies: mitochondrial poisons, radiotherapy/chemotherapy, PARP/ATR inhibitors, metabolic reprogramming agents, mitochondrial quality control modulators, and localized mitochondrial stress induction, each paired with immune checkpoint blockade. The review emphasizes \"controlled ignition\" as a paradigm whereby precisely dosed mitochondrial stress amplifies tumor antigenicity and favorable cytokine landscapes while avoiding chronic immunosuppression. Cytokine networks emerge as both integrators and therapeutic targets of mitochondrial-immune crosstalk.

Interferon-gamma (IFN-γ) signaling is altered in glioblastoma. Moreover, proteolytic enzymes, known as proteases, have been linked to the invasive growth of cancerous cells. In this study, we aimed to identify a glioblastoma-associated protease group and to determine its potential connection with IFN-γ signaling. Using cancer expression databases, we analyzed the differential expression of 35 proteases in glioblastoma and healthy brain tissue, and the relevance of their deregulation to patient survival. We also explored correlations between IFN-γ signaling element expression and upregulated proteases in glioblastoma. Additionally, we analyzed the effect of IFN-γ on the levels of these 35 proteases using a protein microarray and found that cathepsin L (CTSL) was upregulated by IFN-γ. Then, we analyzed the modulation of CTSL by IFN-γ in glioblastoma cells using dot blot, western blot, and immunofluorescence assays. We identified 11 proteases (cathepsin B, Z, C, S (CTSB, CTSZ, CTSC, CTSS), matrix metalloproteinase 2, 7, 9 (MMP2, MMP7, MMP9), a disintegrin and metalloproteinase 9 (ADAM9), urokinase-type plasminogen activator (PLAU), presenilin 1 (PSEN1), and CTSL that were upregulated in glioblastoma tissue compared to healthy brain tissue. The expression of specific elements of the IFN-γ pathway correlated with the expression of some of these proteases in glioblastoma samples. Moreover, IFN-γ affected the intracellular and extracellular levels of proteases (four were upregulated and six were downregulated) in glioblastoma-derived cells. Hence, IFN-γ signaling may play a role in glioblastoma by regulating the expression of some proteases. The CTSL protease was upregulated by IFN-γ and was associated with poor glioblastoma prognoses. Thus, we revealed a protease profile (ADAM9, CTSB, MMP7, CTSC, CTSL, MMP9, and PLAU) associated with glioblastoma progression and further demonstrated that CTSL is regulated by IFN-γ in glioblastoma cells.

IL-6 is of interest due to its proinflammatory action, however, it also exhibits anti-inflammatory effects, supporting metabolism and suppressing associated diseases, such as obesity, diabetes mellitus and metabolic syndrome. The IL-6 receptor (IL-6R) is a type I transmembrane glycoprotein in the plasma membrane of only some cell types, such as macrophages, neutrophils, hepatocytes, and T cells. The function of IL-6R requires another transmembrane glycoprotein of 130 kDa (gp130) which, in contrast to IL-6R, is expressed in many cell types. In addition, a soluble form of the IL-6 receptor (sIL-6R) also plays a role in the function of IL-6. These receptors, gp130 and sIL-6R, are involved in the trans pathway of IL-6 signalling, the activation of which is associated with high IL-6 concentrations, promoting proinflammatory processes that are well known. In contrast, the physiological effects of IL-6 associated with increased insulin secretion, fatty acid oxidation and decreased adipose tissue, which occur due to activation of the IL-6 anti-inflammatory signalling pathway, have been poorly explored. Some studies using IL-6 knockout models suggest that some of the anti-inflammatory effects of IL-6 may be stimulated by low concentrations of IL-6, and are essential to suppressing metabolic alterations.

In this study, we aimed to assess the role and possible mechanisms of MALAT1 in PC progression. Expression of MALAT1 was studied by quantitative real-time polymerase chain reaction (qRT-PCR) in PC tissues. The dual-luciferase assay was performed to validate binding between MALAT1 and miR-141-5p in HEK293 cells. Western blot analysis was performed to examine the expression of transforming growth factor beta (TGF-β) and its receptors, TGFBR1 and TGFBR2. Invasiveness and migration of cultured PANC-1 cells were studied using transwell invasion and migration assays, respectively. A high level of miR-141-5p and low level of MALAT1 were detected in PC tissues, and the level of MALAT1 was shown to significantly correlate with tumour growth and metastasis. In HEK293 cells, miR-141-5p overexpression inhibited the expression of TGFBR1 and TGFBR2, and this inhibition was reversed by overexpression of MALAT1. In PANC-1 cells, MALAT1 was shown to act as a competing endogenous RNA, as the direct target of miR-141-5p. Furthermore, in PANC-1 cells, miR-141-5p overexpression suppressed TGF-induced epithelial-mesenchymal transition (EMT), cell migration, and cell invasion through direct binding to the 3'UTR of TGFBR1 and TGFBR2. Our results indicate that, in PC cells, miR-141-5p suppresses TGFBR1 and TGFBR2 expression and further inhibits TGF-β-induced EMT, cell migration, and cell invasion, which are reversed by overexpression of MALAT1, demonstrating that MALAT1 and miR-141-5p may be important regulators in the initiation and metastasis of PC.</p>","PeriodicalId":11749,"journal":{"name":"European cytokine network","volume":"35 3","pages":"28-37"},"PeriodicalIF":2.2,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142946697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
