Nicotinamide N-methyltransferase is related to MELF pattern invasion in endometrioid carcinoma [RNA-seq_pico input]

Project description:In endometrioid carcinoma (EC), grade 1 (G1) EC is generally associated with a good prognosis. However, in a minority of G1, we often find a more aggressive histological pattern: MELF (microcystic, elongated, and fragmented) pattern. We previously revealed that EC with high expression of S100A4 and serum deprivation-response protein (SDPR) was related to MELF pattern invasion. However, the molecular feature of the invasive front area of MELF pattern has not been investigated. In the current study, we searched for genes preferentially expressed in the invasive front area of EC with MELF pattern by using laser microdissection and RNA sequencing, and revealed that Nicotinamide N-methyltransferase (NNMT) is related to invasiveness of MELF pattern. We confirmed that NNMT expression was high in the invasive front area of MELF pattern in immunohistochemical analysis. Moreover, using endometrioid carcinoma cell lines, we showed that NNMT promotes migration, invasion, colony formation, epithelial-mesenchymal transition (EMT), and chemoresistance. We speculated that depletion of NNMT promotes histone methylation and leads to tumor suppression because NNMT consumes S-adenosyl methionine (SAM), which is an essential methylation cofactor. We showed that NNMT-knockout cells the expression of H3K9me2 was enhanced. We speculate that methylation of H3K9 lead to repress the transcription of various oncogenic genes by performing RNA sequencing using NNMT-knockout cell lines. Our findings showed the possibility that NNMT inhibitors, which are expected to be used for the treatment of metabolic disorders, is effective for the treatment of an aggressive EC. This is the first report of the gene analysis focused on the morphological changes of MELF pattern invasion of EC.

Nicotinamide N-methyltransferase is related to MELF pattern invasion in endometrioid carcinoma.

Project description:Grade 1 (G1) endometrioid carcinoma (EC) is relatively a good prognosis. However, in a minority of cases, G1 shows an aggressive histological pattern known as the microcystic, elongated, and fragmented (MELF) pattern. We previously reported that EC with high expression levels of S100A4 and serum deprivation-response protein (SDPR) was related to MELF pattern invasion. However, the molecular features of the invasive front area of the MELF pattern have not been investigated.

A Proteogenomic View of Synchronous Endometrioid Endometrial and Ovarian Cancer

Project description:Purpose: Increasing genomics-based evidence suggests that synchronous endometrial and ovarian cancer (SEOC) represents clonally related primary and metastatic tumors. A systematic analysis of the global protein landscape of SEOCs, heretofore lacking, could reveal functional and disease-specific consequences of known genetic alterations, the directionality of metastasis, and accurate histological markers to distinguish SEOCs from single-site tumors. Experimental Design: We performed a systematic proteogenomic analysis of 29 patients diagnosed with SEOC at three international gynecologic oncology treatment centers (Chicago, Vancouver, Tübingen). For direct comparison to single-site tumors, we included 9 patients with single-site endometrioid ovarian and 26 patients with single-site endometrial endometrioid cancer. For all 64 patients, we performed sequencing of a 275-gene cancer panel combined with compartment-resolved mass spectrometry (MS) based proteomics of consecutive tissue sections to compare global (6,000+ proteins), tumor, and stromal proteomes. Results: DNA-based panel sequencing confirmed that most SEOCs are clonally related, suggesting primary and metastatic disease. These findings were further substantiated on the global proteome level, uncovering pronounced differences between SEOCs and single tumors and underscoring the importance of the stromal proteome in defining and identifying SEOCs. Our integrated proteogenomic approach confirmed that SEOCs more closely resemble endometrial endometrioid than endometrioid ovarian cancers. Conclusions: The integrated proteogenomic data show that SEOCs are distinguishable from endometrial endometrioid or endometrioid ovarian cancers. Based on their proteogenomic similarity to endometrial endometrioid cancers, we conclude that most synchronous endometrial and ovarian cancers represent primary endometrial endometrioid cancers that have metastasized to the ovary.
