Single Nuclei RNA Sequencing of Uterine Serous Carcinoma

Project description:Significant racial disparities exist between Black and White patients with uterine serous carcinoma (USC). While the reasons for these disparities are unclear, but several studies have demonstrated significantly distinct rates of driver mutations between racial groups, including TP53. However, limited research has investigated the transcriptional differences of the tumors between these groups, or the composition of the tumor microenvironment (TME) between these groups. Here, we report the findings from the first single nuclei RNA-sequencing experiment conducted on USC tumors. We find that there are significant differences between the tumors of Black and White patients. Tumors exhibited differential expression of specific genes associated with aggressiveness, such as PAX8, and axon guidance and synaptic signaling pathways in Black and White patients. We also demonstrated that differences in T cell and macrophage populations exist between benign and tumor tissues in the TME of USC, as well as between racial groups. Furthermore, we investigated the connection between PAX8 overexpression and immunosuppression in USC through regulation of several cytokines and chemokines. Notably, we show for the first time that PAX8 activity can influence macrophage gene expression and protein secretion. These studies provide a detailed understanding of USC and a basis for using racial information in USC treatment decisions.

Comparative DNA methylome analysis of endometrioid adenocarcinoma, uterine papillary serous carcinoma, and normal endometrium

Project description:Classically, there are two types of endometrial cancer, endometrioid adenocarcinoma (EAC), or Type I; and uterine papillary serous carcinoma (UPSC), or Type II. These two types of cancers exhibit distinct DNA methylation levels in promoters of many genes. In EAC, many tumor suppressor genes were silenced due to DNA hypermethylation at their promoter region. However, promoters of many of these genes remained unmethylated in UPSC. Here, we described complete DNA methylome maps of endometrioid adenocarcinoma, uterine papillary serous carcinoma, and normal endometrium, by applying a combined strategy of methylated DNA immunoprecipitation sequencing (MeDIP-seq) and methylation-sensitive restriction enzyme sequencing (MRE-seq). We took a complementary and orthogonal approach to identify DNA methylation changes unique to the two endometrial cancer subtypes in an unbiased fashion. We generated complete DNA methylome maps for endometrioid adenocarcinoma (EAC, three samples), uterine papillary serous carcinomas (UPSC, three samples), and normal endometrium (pooled samples) by integrating data from methylated DNA immunoprecipitation sequencing (MeDIP-seq) and methylation-sensitive restriction enzyme sequencing (MRE-seq).

Mapping three-dimensional intratumor proteomic heterogeneity in uterine serous carcinoma by multiregion microsampling

Project description:Uterine serous carcinoma (USC) represents only a small proportion of all uterine cancer cases, but patients with this aggressive subtype typically have high rates of chemotherapy resistance, disease recurrence, and constitute a disproportionately high percentage of the deaths. Improving the clinical management of USC is predicated by better characterization of the tumor microenvironment (TME) and the molecular features driving disease pathology. To improve our understanding of intratumoral heterogeneity (ITH) within the USC TME, we investigated proteome and transcriptome alterations in spatially resolved laser microdissection (LMD) enriched cellular subpopulations from nine USC patient tumor tissue specimens. LMD enriched samples were analyzed via liquid chromatography-tandem mass spectrometry (LC-MS/MS), reverse phase protein microarray (RPPA), and targeted RNA-sequencing (RNA-seq).

Human Uterine Serous Carcinoma cells and tumors response to CTX-439

Project description:This study aimed to investigate gene-expression alterations induced by the CDK12 inhibitor CTX-439 in uterine serous carcinoma (USC). USC cell lines (ARK1, ARK2) and patient-derived xenograft (PDX) models (USC1, USC2) were subcutaneously implanted into mice, and treated orally with either CTX-439 (CDK12 inhibitor) or vehicle control. RNA was collected from harvested tumors 6 hours after the final treatment. Differential gene expression analysis revealed significant downregulation of homologous recombination (HR)-related and DNA repair genes in CTX-439-treated groups, highlighting a potential therapeutic mechanism of action for CTX-439 in USC.
