An activation of interleukin-17C signaling drives cancerogenesis of endometriosis

ABSTRACT: Endometriosis -associated ovarian carcinoma (EAOC) is mostly malignant transformation from endometriomas. However, the endometriosis cancerogenesis remains to be established. Using spatial transcriptomic of human specimens of normal, endometriomas and EAOC, activation of Interleukin-17C (IL-17C) signaling is identified, with higher IL-17 receptor E (IL-17RE) expression in endometriotic cells, to be associated with cancerogenesis and which has no previous association with EAOC. Elevated IL-17C concentration is found in peritoneal fluid in women with ovarian cancer and IL-17RE-overexpressed endometriosis mice. In particular, IL-17C knockout reduces peritoneal fluid IL-17C concentration and inhibits ectopic lesion growth in endometriosis mice. Besides, the role of IL-17C in the endometriosis cancerogenesis was investigated by blocking the IL-17C/IL-17RE, modulating IL-17RE and neutralizing IL-17C in endometriotic cells, endometrial organoids and endometriosis mice. These data defined peritoneal fluid-mediated endometriosis cancerogenesis through IL-17C regulation and suggests that IL-17C/IL-17RE can thus potentially serve as novel targets for with high IL-17C.

Human keratinocytes stimulated with IL-17C

Project description:IL-17C is important for the pathogenesis of inflammatory diseases such as IBD and psoriasis. We found that IL-17C is highly induced in a murine model of psoriasis. Recent results suggest that IL-17C can target epithelial cells that express both IL-17RA and IL-17RE receptor chains. Here we identify genes induced in response to IL-17C treatment of human keratinocytes to provide the tools for dissection of the IL-17C signaling pathway.

Gene expression profiles of endometriosis

Project description:Endometriosis is a common disease seen by gynecologists. Clinical features involve pelvic pain and unexplained infertility. Although endometriosis is pathologically characterized by endometrial tissue outside the normal uterine location, endometriosis is otherwise not easily explained. Endometriomas, endometriotic cysts of the ovary, typically cause pain and distortion of pelvic anatomy. To begin to understand the pathogenesis of endometriomas, we carried out transcriptome:microRNAome analysis of endometriomas and eutopic endometrium, using gene expression arrays and next generation small RNA sequencing technology. Keywords: two group comparison Patients undergoing surgery for endometriomas, suspected endometriosis, pelvic pain, abnormal uterine bleeding, pelvic organ prolapse, or uterine leiomyomas were approached for participation. After informed consent, the patients underwent scheduled surgical procedure. Tissues were collected either as cyst wall of endometrioma or endometrial curettage of hysterectomy specimen and placed directly into RNALater (Ambion, Austin, TX) and eventually frozen at -80?C. Samples were designated as endometriomas or non-endometriosis control endometrium based on surgical pathology reports. Total RNA was isolated from frozen tissue. High quality RNA was subjected to Illumina’s Human WG-6 version 2.0 BeadChips (Illumina). . *** This Series represents the transcriptome component of the study. ***

Induction of alternative proinflammatory cytokines accounts for sustained psoriasiform skin inflammation in IL-17C+IL-6KO mice [array]

Project description:IL-6 inhibition has been unsuccessful in treating psoriasis, despite high levels of tissue and serum IL-6 in patients. Additionally, de novo psoriasis onset has been reported following IL-6 blockade in rheumatoid arthritis patients. To explore mechanisms underlying these clinical observations, we backcrossed an established psoriasiform mouse model (IL-17C+ mice) with IL-6 deficient mice (IL-17C+KO) and examined the cutaneous phenotype. IL-17C+KO mice initially exhibited decreased skin inflammation, however this decrease was transient and reversed rapidly, concomitant with increases in skin Tnf, Il36α/β/γ, Il24, epigen and S100a8/a9 to levels higher than those found in IL-17C+ mice. Comparison of IL-17C+ and IL-17C+KO mouse skin transcriptomes with that of human psoriasis skin, revealed significant correlation among transcripts of psoriasis patient skin and IL-17C+KO mouse skin, and confirmed an exacerbation of the inflammatory signature in IL-17C+KO mice that aligns closely with human psoriasis. Transcriptional analyses of IL-17C+ and IL-17C+KO primary keratinocytes confirmed increased expression of proinflammatory molecules, suggesting that in the absence of IL-6, keratinocytes increase production of numerous additional proinflammatory cytokines. These preclinical findings may provide insight into why arthritis patients being treated with IL-6 inhibitors develop new onset psoriasis and why IL-6 blockade for the treatment of psoriasis has not been clinically effective.

Peritoneal fluid from subjects with endometriosis regulates gene expression in cultured endometrial cells

Project description:Purpose: This study was undertaken to evaluate the effect of peritoneal fluid from subjects with differing stages of endometriosis on gene expression in endometrial stromal cells. Methods: Peritoneal fluid from subjects with minimal, moderate, and severe stages of endometriosis or without endometriosis (controls) was collected, filtered and separated from peritoneal cells. Telomerase – immortalized human endometrial stromal cells (T-HESC) were treated with the peritoneal fluid samples for 48 hours. RNA was isolated from treated cells and processed for DNA microarray. Results: 162 genes were found to be differentially expressed in T-HESC cells treated with peritoneal fluid from subjects with differing stages of endometriosis. Three of the differentially expressed genes were chosen for confirmatory studies using quantitative RT-PCR; these were interleukin 8, corin and matrix metalloproteinase 3. The primary gene ontologies identified by microarray highlight functions expected to be involved in the establishment of endometriosis, such as proteases, signal transduction, defense and immune system, cell adhesion, cell cycle and cell death, cytoskeleton, transcriptional regulation and translation, extracellular matrix, and enzymes and metabolism. Conclusions: This study demonstrated that the severity of endometriosis affected the factors present in peritoneal fluid which, in turn, affected gene expression in endometrial stromal cells.

miRNome of endometriotic lesion

Project description:miRNA high-throughput sequencing was used to investigate endometriosis lesion-specific miRNA expression profiles by comparing a set of paired samples of peritoneal endometriotic lesions and matched healthy surrounding tissue together with eutopic endometrium of the same patients. We found that miRNAs of surrounding peritoneal tissue mask most of the miRNA expression differences that could originate from endometriotic tissue and thus only miRNAs with significantly different levels in the endometriotic lesions compared to peritoneal tissue were detected. According to the results of this study, two miRNAs – miR-34c and miR-449a showed remarkably higher expression in lesions compared to healthy tissue.

IL-17C is a driver of damaging inflammation duringNeisseria gonorrhoeaeinfection of human Fallopian tube

Project description:The human-restricted pathogenNeisseria gonorrhoeaeascends into the upper female reproductive tract to cause damaging inflammation within the Fallopian tubes (salpingitis) and pelvic inflammatory disease (PID), increasing the risk of infertility and life-threatening ectopic pregnancy. The loss of ciliated cells from the epithelium is thought to be both a consequence of inflammation and a cause of the associated adverse sequelae. However, the links between infection, inflammation, and ciliated cell extrusion remain unresolved. With the use ofex vivocultures of human Fallopian tube paired with RNA sequencing we defined the tissue response to gonococcal challenge, identifying cytokine, chemokine, cell adhesion, and apoptosis related transcripts not previously recognized as potentiators of gonococcal PID. Unexpectedly, the cytokine IL-17C was one of the most highly induced genes. Yet, this cytokine has no previous association with gonococcal disease nor any sexually transmitted infection and thus it was selected for further characterization in our model. We show that human Fallopian tubes express the IL-17C receptor (IL-17RE) on the epithelial surface and that treatment with purified IL-17C induces pro-inflammatory cytokine secretion in addition to sloughing of the epithelium and generalized tissue damage. These results demonstrate a previously unrecognized but critical role of IL-17C in the damaging inflammation induced by gonococci in a human explant model of PID.
