CD54âNOTCH1 axis controls tumor initiation and cancer stem cell functions in human prostate cancer

ABSTRACT: Using high sensitive ArrayStar Human, we detected differentially expressed genes and circRNAs, these part of data is the aberrent expressed genes. 12 Male NOD/SCID mice were obtained from the Animal Center of the Chinese Academy of Medical Science (Beijing, China). For xenograft generation, 1Ã10^6 LNCaP cells were subcutaneously injected into the backs of NOD/SCID mice (n=24). When tumors reached a diameter of 5 mm after 3 d, mice were randomly divided into two groups without castration (12 per group). Mice in the treatment group were administered with cisplatin at a dose of 5 mg/kg every 3 d for 30 d. Mice in the control group were treated with vehicle PBS. Tumors were taken out for microarray assay after 30 d.

Expression data from LNCaP cells

Project description:Prostate Cancer Stem Cells (CSCs) are considered one of the main reasons the tumor recurrence after chemotherapy. Here we employed a chemoresistant xenograft prostate cancer model in NOD/SCID mice and found CD54 is a reliable new marker for prostate CSCs. Gene expression profile were utilized to analyze stemness-related genes in cancer stem cells. 12 Male NOD/SCID mice were obtained from the Animal Center of the Chinese Academy of Medical Science (Beijing, China). For xenograft generation, 1Ã106 LNCaP cells were subcutaneously injected into the backs of NOD/SCID mice (n=24). When tumors reached a diameter of 5 mm after 3 d, mice were randomly divided into two groups without castration (12 per group).

Circular RNA cFUT8 acts as an epithelialâmesenchymal transition trigger in liver cancer.

Project description:Using the highly sensitive cricRNA array, we screened 13617 circRNAs abundant in the human liver cancer and Adjacent normal liver tissues, and the function of differentially expressed circRANs were analyzed by bioinformatics. The results revealed that cFUT8 controls epithelialâmesenchymal transition in liver cancer by cFUT8/miR-548c-3p/FUT8 axis. In this study, three cases of liver cancer samples were used to acquire the circRNA expression profiling, and qRT-PCR was employed to confirm the results of circRNA microarrays. The functions of the differentially expressed circRNA were analyzed by bioinformatics methods. Finally, through in vivo and ex vivo experimentsï¼the âcFUT8/miR-548c-3p/FUT8 axisâ was found to control epithelialâmesenchymal transition in liver cancer

Bladder cancer lncRNA expression profiling

Project description:Using the highly sensitive lncRNA array, we screened the lncRNAs abundant in the human bladder cancer and Adjacent normal bladder tissues, and the function of differentially expressed lncRNAs were analyzed by bioinformatics. The Arraystar Human lncRNA Array (8x15K, Arraystar) and whole human mRNA Array (4x44K, Arraystar) and was used to profile differentially expressed lncRNAs and genes in bladder cancer vs. normal tissues following the manufacturerâs instructions. Briefly, extracted RNA template (1mg) was reversely transcribed into cDNA and digested into fragments with endonucleases. These fragments were labeled with DNA labeling reagent and labeled cDNAs were hybridized to the microarray via incubation at 45Â°C and rotated at 60 rpm for 17 h. Following washing and staining, the arrays were scanned using a GeneChip Scanner3000 with GeneChip Operating Software.

A discovery-based proteomics approach identifies protein disulfide isomerase (PDIA1) as a biomarker of β cell stress in type 1 diabetes

Project description:Background: Activation of stress pathways intrinsic to the β cell are thought to both accelerate β cell death and increase β cell immunogenicity in type 1 diabetes (T1D). However, information on the timing and scope of these responses is lacking. Methods: To identify temporal and disease-related changes in islet β cell protein expression, SWATH-MS/MS proteomics analysis was performed on islets collected longitudinally from NOD mice and NOD-SCID mice rendered diabetic through T cell adoptive transfer. Findings: In islets collected from female NOD mice at 10, 12, and 14 weeks of age, we found a time-restricted upregulation of proteins involved in the maintenance of β cell function and stress mitigation, followed by loss of expression of protective proteins that heralded diabetes onset. Pathway analysis identified EIF2 signaling and the unfolded protein response, mTOR signaling, mitochondrial function, and oxidative phosphorylation as commonly modulated pathways in both diabetic NOD mice and NOD-SCID mice rendered acutely diabetic by adoptive transfer, highlighting this core set of pathways in T1D pathogenesis. In immunofluorescence validation studies, β cell expression of protein disulfide isomerase A1 (PDIA1) and 14-3-3b were found to be increased during disease progression in NOD islets, while PDIA1 plasma levels were increased in pre-diabetic NOD mice and in the serum of children with recent-onset T1D compared to age and sex-matched non-diabetic controls. Interpretation: We identified a common and core set of modulated pathways across distinct mouse models of T1D and identified PDIA1 as a potential human biomarker of β cell stress in T1D.

Transcription profiling of pancreata, submandibular, and lacrimal glands from NOD-scid and C57Bl/6-scid mice to study the gene expression patterns of nonobese diabetic mice.

Project description:Prior to the onset of autoimmune destruction, type 1 diabetic patients and an animal model thereof, the nonobese diabetic (NOD) mouse, show morphological and functional abnormalities in target organs, which may act as inciting events for leukocyte infiltration. To better understand these abnormalities, but without the complications associated with inflammatory infiltrates, we examined genes expressed in autoimmune target tissues (pancreas, submandibular glands, and lacrimal glands) of NOD/scid mice and of autoimmune-resistant C57BL6/scid mice. Experiment Overall Design: Pancreata (6 weeks old mice), submandibular (9 and 15 weeks), and lacrimal glands (15 weeks) from individual NOD-scid and B6-scid mice were isolated for RNA extraction and hybridization on Affymetrix microarrays.

Single cell RNA-sequencing analysis of islets from NOD.SCID mice on chow and hydrolyzed casein diets

Project description:Protein source in diet greatly influences the incidence of type-1 diabetes (T1D) in non-obese diabetic (NOD) mouse colonies. NOD mice fed a diet containing hydrolyzed casein (HC) as the sole protein source are protected from T1D. Exposure to HC also reduced beta-cell insulin secretion during glucose challenge suggesting that beneficial changes to beta-cell physiology might protect NOD mice from T1D. We used single cell RNA sequencing (scRNAseq) to contrast the transcriptional profiles of beta-cells and from the pancreatic islets of Langerhans of NOD mice with the scid mutation (scid mice were used to avoid confouding influence of infiltrating leukocytes) fed a 20% HC diet or a standard chow diet.
