Project description:RCC cells (786-O) were transfected with VHL. The parental cell line should be compared to the transfectant (+ VHL) under nomoxia as well as under hypoxia conditions. We want to distinct the VHL-mediated gene expression from the hypoxia-mediated and study the influence of both on the cellular metabolism. RNA of VHL-negative 786-O RCC cell line and VHL-transfectants incubated during normoxia and hypoxia conditions were analysed by cDNA microarray.

Project description:Background: Advanced Renal cell carcinoma (RCC) is therapeutically challenging. RCC progression is facilitated by mesenchymal stem/stromal cells (MSCs) that exert remarkable tumor tropism. The specific mechanisms mediating MSCs’ migration to RCC remain unknown. Here, we comprehensively analyzed RCC secretome to identify MSCs attractants. Methods: Conditioned media (CM) were collected from five RCC-derived cell lines (Caki-1, 786-O, A498, KIJ265T, KIJ308T) and non-tumorous control cell line (RPTEC/TERT1) and analyzed using cytokine arrays targeting 274 cytokines in addition to global CM proteomics. MSCs were isolated from bone marrow of patients undergoing standard orthopedic surgeries. RCC CM and the selected recombinant cytokines were used to analyze their influence on MSCs migration and microarray-targeted gene expression. The expression of genes encoding cytokines was evaluated in 100 matched-paired control-RCC tumor samples. Results: When compared with normal cells, CM from advanced RCC cell lines (Caki-1, KIJ265T) were the strongest stimulators of MSCs migration. Targeted analysis of 274 cytokines and global proteomics of RCC CM revealed decreased DPP4 and EGF, as well as increased AREG, FN1, and MMP1, with consistently altered gene expression in RCC cell lines and tumors. AREG and FN1 stimulated, while DPP4 attenuated MSCs migration. RCC CM induced MSCs’ transcriptional reprogramming, stimulating the expression of CD44, PTX3, and RAB27B. RCC cells secreted hyaluronic acid (HA), a CD44 ligand mediating MSCs’ homing to the kidney. AREG emerged as an upregulator of MSCs’ transcription. Conclusions: advanced RCC cells secrete AREG, FN1 and HA to induce MSCs migration, while DPP4 loss prevents its inhibitory effect on MSCs homing. RCC secretome induces MSCs’ transcriptional reprograming to facilitate their migration. The identified components of RCC secretome represent potential therapeutic targets. We used microarrays to determine the effect of the conditioned media (CM) collected from two RCC-derived cell lines (Caki-1, KIJ265T) and non-tumorous control cell line (RPTEC/TERT1) on the transcriptome change in mesenchymal stem/stromal cells (MSCs).

Project description:Introduction/aim: Renal cell cancer (RCC) is the most frequent kidney malignancy. Here, we aimed to analyze RCC secretome to find key molecules involved in tumor microenvironment regulation.
Methods: Conditioned media from five RCC-derived cell lines (Caki-1, KIJ-265T, KIJ-308T, 786-O, and A498) and a non-cancerous proximal tubules (RPTEC) were used for mass spectrometry based proteomic analysis. The results were evaluated using Gene Onthology algorithms.
Results: When compared with RPTEC, CM of Caki-1 and KIJ265T contained 587 and 802 aberrantly expressed proteins, respectively. Remarkably, there were 360 proteins commonly found in CM from Caki-1 and KIJ265T cells, with striking 348 proteins with changes in similar directions. 786-O CM expressed 612, A498 569, and KIJ308T 802 proteins. All cell lines shared 124 aberrantly expressed CM proteins, with 119 proteins with changes in the same direction. Top commonly downregulated proteins included SCIN, CBR4, MUC1, PELP1, LSM1, while top upregulated proteins were BZW2, COLGALT1, EEF1A2, CSDE1, INHBA, and STAT1. GO analysis of cellular components related to the identified proteins revealed that 63 proteins were associated with extracellular exosomes.
Conclusion: Different RCC cell lines secrete proteins, commonly altered when compared with normal kidney proximal tubules. 53% of these proteins are associated with extracellular exosomes.

Project description:To identify target genes of cancer-related microRNAs in human cancer, several cell lines (bladder cancer, prostate cancer, renal cell carcinoma, esophageal squamous cell carcinoma, and head and neck squamous cell carcinoma) were subjected to Agilent whole genome microarrays. Human cancer cell lines (BOY, T24, A498, 786-O, caki-1, LNCap, PC3, TE2, T.Tn, FaDu, SAS, HSC3, and IMC-3) were transfected with miRNAs (miR-375, miR-145, miR-200a, miR-200b, miR-200c, miR-141, miR-429, miR-138, miR-218, miR-874, miR-31, miR-222, miR-1285, and miR-206) or siRNAs (si-FOXA1_1, si-FOXA1_3, and si-TAGLN2). The miRNA-transfected human cancer cell lines were compared to control cell lines.

Project description:In recent years, genome wide RNA expression analysis has become a routine tool that offers a great opportunity to study and understand the key role of genes that contribute to carcinogenesis. Various microarray platforms and statistical approaches are implemented to identify genes that might serve as prognostic bio-markers and used for anti-tumor therapies in future. Metastatic renal cell carcinoma (mRCC) is a serious life-threatening disease. There are few treatment options for metastatic RCC patients. We performed one-color microarray gene expression (4X44K) analysis of metastatic RCC cell line Caki-1 and healthy kidney cell line ASE-5063. 1921 genes were differentially expressed in Caki-1 cell line (1023 up-regulated and 898 down-regulated). Gene set enrichment analysis (GSEA) and Ingenuity Pathway Analysis (IPA) approach was used to analyse these differentially expressed data from Caki-1. The objective of this research is to identify complex biological changes that occur during metastatic development using Caki-1 as a model RCC cell line. Our data suggests that there are multiple de-regulated pathways associated with mccRCC including ILK Signaling, Leukocyte Extravasation Signaling, IGF-1 Signaling, CXCR4 Signaling, and PI3K/AKT Signaling. The IPA upstream analysis predicted top transcriptional regulators which are wither activated or inhibited such as ER, TP53, KDM5B, SPDEF, CDKN1A. The GSEA approach was used to further confirm enriched pathway data following IPA analysis.

Project description:The recent advances in anti-cancer treatments have led to a steady increase in the number of cancer survivors, paradoxically also enhancing the number of HF patients who suffer from the undesired cardiotoxic side effects of these anti-tumor treatments. Therapeutic options to reduce or reverse chemotherapy-induced HF are not available. Circular RNAs exhibit high druggability due to the high stability of their special closed loop structure. Circ-INSR overexpression prevents doxorubicin-induced cardiac dysfunction in preclinical murine and human models. Circ-INSR mimics produced in vitro also reduced cardiomyocyte death under doxorubicin stress, highlighting the potential of Circ-INSR-based RNA therapy for future clinical applications.
