Single cell sequencing of adrenocortical tumor tissue utilizing the scFAST-seq method

ABSTRACT: Single-cell RNA sequencing (scRNA-seq) is a technology that allows for the analysis of gene expression at the level of individual cells. In many cases, droplet microfluidics are used for preparing DNA libraries. SeekOne DD scFAST-seq from Beijing SeekGene employs semi-random primers, offering advantages in detecting transcripts, particularly non-polyadenylated transcripts and regions that are distant from the polyadenylated RNA tail. The introduction of new strategies in scRNA-seq represents a promising approach for research, such as studying the properties of adrenocortical tumors. This study aims to investigate the biological properties of adrenocortical tumor samples by SeekOne scFAST-seq methodology.

Effects of FSCN1 inactivation on protein expression in human adrenocortical cancer cells

Project description:Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with a high risk of relapse and metastatisation. The actin-bundling protein fascin (FSCN1) is overexpressed in aggressive ACC and represents a reliable prognostic indicator. FSCN1 has been shown to synergize with the Rho/Rac GEF VAV2 in enhancing the invasion properties of ACC cancer cells. Based on those results, we investigated the effects of FSCN1 inactivation by CRISPR/Cas9 or pharmacological blockade on the invasive properties of ACC cells, both in vitro and in an in vivo metastatic ACC zebrafish model. Moreover, to assess the impact of FSCN1 inactivation on global gene and protein expression in H295R cells, we performed RNA-seq and proteomic profiling of control and FSCN1 knock-out (KO) clones.

CGH analysis of adrenocortical tumors

Project description:Adrenocortical tumors are common; their prevalence may reach up to 5-7% in pathological series. Most of them are benign and hormonally inactive, however, rare hormone-secreting (aldosterone and cortisol) and malignant forms are associated with significant morbidity and mortality. The prognosis of adrenocortical cancer (ACC) is poor with an overall five-year survival below 30 %. In this study, CGH analysis was performed on 4 ACC (adrenocortical carcinoma), 4 IA (hormonally inactive adrenocortical adenoma) and 3 CPA (cortisol producing adrenocortical adenoma) samples. Tissue digestion, labeling, hybridization and data analysis of genomic DNA were performed according to the Agilent Technologies (Santa Clara, CA) protocol version 2.0 for 105 K arrays. As expected, many of the observed aberrations were generally consistent with those of other preciously published data and will provide the basis for determination how genomic diversity impacts biological function and human diseases, such as cancer.

Identification of new TCF21 targets in adrenocortical carcinoma cells

Project description:Transcription factor 21 (TCF21) directly binds and regulates SF1 in tumor and normal adrenocortical cells, and both are involved in the development and steroidogenesis of the adrenal cortex. TCF21 is a tumor suppressor gene and its expression is reduced in malignant tumors. In adrenocortical tumors, it is less expressed in adrenocortical carcinomas (ACC) than in adrenocortical adenomas (ACA) and normal tissue. However, a comprehensive analysis to identify TCF21 targets have not yet been conducted in any type of cancer. In this study, we performed Chromatin Immunoprecipitation and Sequencing (ChIP-Seq) in adrenocortical carcinoma cell line (NCI-H295R) overexpressing TCF21, with the aim of identifying TCF21 new targets. The five most frequently identified sequences corresponded to the PRDM7, CNTNAP2, CACNA1B, PTPRN2 and KCNE1B genes. Validation experiments showed that, in NCI-H295R cells, TCF21 regulates gene expression positively in PRDM7 and negatively in CACNA1B. Recently, it was observed that the N-type calcium channel v2.2 (Cav2.2) encoded by CACNA1B gene is important in Angiotensin II signal transduction for corticosteroid biosynthesis in NCI-H295R adrenocortical carcinoma cells. Indeed, TCF21 inhibits CACNA1B and Cav2.2 expression in NCI-H295R. In addition, in a cohort of 55 adult patients with adrenocortical tumor, CACNA1B expression was higher in ACC than ACA, and was related to poor disease-free survival in ACC patients. These results suggest a mechanism of steroidogenesis control by TCF21 in adrenocortical tumor cells, in addition to the control observed through SF1 inhibition. Importantly, steroid production could impair tumor immunogenicity, contributing to the immune resistance described in adrenal cancer.

Succinate mediates inflammation-induced adrenocortical dysfunction

Project description:Inflammation leads the hypothalamus-pituitary-adrenal (HPA) axis activation and increased production of glucocorticoids, which produced by the adrenal cortex, exert potent anti-inflammatory effects. The use of omics, including proteomics revealed metabolic changes in steroidogenic adrenocortical cells, including downregulation of the tricarboxylic acid (TCA) cycle and oxidative phosphorylation, decreased ATP production and induction of oxidative stress after lipopolysaccharide (LPS)-induced inflammation.

Analysis of circulating microRNAs in adrenocortical tumours

Project description:Differential diagnosis of adrenocortical adenoma and carcinoma is of pivotal clinical relevance, as the prognosis and clinical management of benign and malignant adrenocortical tumours is entirely different. Circulating microRNAs are promising biomarker candidates of malignancy in several tumours. In the present study we investigate circulating microRNAs in adrenocortical tumours and to evaluate their potential applicability as biomarkers of malignancy.
