Project description:Cordycepin, a 3-deoxyadenosine, a traditional Chinese medicine. Studies have demonstrated that cordycepin could modulate multiple signaling pathways to induce cancer cell death. This study aims to determine the genes regulated by Cordycepin and clarify the possible molecular mechanism underlying their action.

Project description:The purpose of this study was to identify differentially-expressed genes between WT MA-10 mouse tumor Leydig cells and MA-10 cells in which the steroidogenic acute regulatory protein (STAR) is knocked out.

Project description:To study the potential tumorigenic effect of two activating mutations of hLHR identified in patients, we generated in vitro cell model using mouse Leydig MA-10 cells. The two mutations, Asp578His and Asp578Gly, were stably transfected to MA-10 cell to create MA-10-Asp578His and MA-10-Asp578Gly line. The profile of expressed genes in cells expressing the mutated hLHR was compared with that of control cells using cDNA microarrays with NIA mouse clone sets. Keywords: Genetic modification analysis

Project description:Cordycepin (3â deoxyadenosine) is a biologically active compound that, when incorporated during RNA synthesis in vitro, provokes chain termination due to the absence of a 3â hydroxyl moiety. We were interested in the effects mediated by this drug in vivo and analysed its impact on RNA metabolism of yeast. Our results support the view that cordycepin-triphosphate (CoTP) is the toxic component that is limiting cell growth through inhibition of RNA synthesis. Unexpectedly, cordycepin treatment modulated 3â end heterogeneity of ACT1 and ASC1 mRNAs and rapidly induced extended transcripts derived from CYH2 and NEL025c loci. Moreover, cordycepin ameliorated the growth defects of poly(A) polymerase mutants and the pap1-1 mutation neutralized the effects of the drug on gene expression. Our observations are consistent with an epistatic relationship between poly(A) polymerase function and cordycepin action and suggest that a major mode of cordycepin activity reduces 3â end formation efficiency independently of its potential to terminate RNA chain elongation. Finally, chemical-genetic profiling revealed genome-wide pathways linked to cordycepin activity and identified novel genes involved in poly(A) homeostasis. Keywords: response to drug treatment Each experiment was performed as triplicate. We analyzed RNA obtained from wild-type cells, from wild-type cells treated with 40 microgram/ml cordycepin for 1 hour, from pap1-1 mutant cells grown at permissive temperature (25°C) and from pap1-1 mutant cells grown at permissive temperature (25°C) treated with 40 microgram/ml cordycepin for 1 hour.

Project description:To perform high-throughput, transcriptome-wide analysis on RAW 264.7 cells treated with cordycepin with and without bacterial lipopolysaccharide (LPS) to investigate cordycepin's anti-inflammatory properties and determine whether particular classes of RNAs were sensitive to cordycepin.

Project description:Cordycepin (3’ deoxyadenosine) is a biologically active compound that, when incorporated during RNA synthesis in vitro, provokes chain termination due to the absence of a 3’ hydroxyl moiety. We were interested in the effects mediated by this drug in vivo and analysed its impact on RNA metabolism of yeast. Our results support the view that cordycepin-triphosphate (CoTP) is the toxic component that is limiting cell growth through inhibition of RNA synthesis.

Project description:Cordycepin was widely considered as a direct tumor-suppressive drug, however, and as of now few studies have been presented to investigate the effect of cordycepin therapy to the tumor microenvironment (TME). In our study, we demonstrated that cordycepin would decrease the function of M1-like macrophage in TME, and also contribute to macrophage polarization (M2-macrophage). Herein, we tried to establish a combined therapeutic strategy of cordycepin and anti-CD47 antibody. Using single cell RNA sequencing, we improved that the combined treatment would significantly increase the effect of cordycepin, which would reactivate macrophages and reverse macrophage polarization. And then, the combined treatment would regulate the proportion of CD8+T cells to increase the PFS for digestive tract malignancy patients. Finally, Flow cytometry was used to validate the change of percentage for TAM and TIL. Our finding suggests the combined treatment of cordycepin and anti-CD47 mAb could significantly increase tumor suppression, which could increase M1-macrophage and decrease M2-macrophage. The PFS for digestive tract malignancy patients would be increased though regulation of CD8+T cells.

Project description:The mitochondrial translocator protein (TSPO) has been shown to bind cholesterol with high affinity and is involved in mediating its availability for steroidogenesis. We recently reported that targeted Tspo gene deletion in MA-10 mouse tumor Leydig cells resulted in reduced cAMP-stimulated steroid formation and significant reduction in the mitochondrial membrane potential (ΔΨm) compared to control cells. We hypothesized that ΔΨm reduction in the absence of TSPO probably reflects the dysregulation and/or maintenance failure of some basic mitochondrial function(s). To explore the consequences of TSPO depletion via CRISPR-Cas9-mediated deletion (indel) mutation in MA-10 cells, we assessed the transcriptome changes in TSPO-mutant versus wild-type (Wt) cells using RNA-seq. Gene expression profiles were validated using real-time PCR. We report herein that there are significant changes in nuclear gene expression in Tspo mutant versus Wt cells. The identified transcriptome changes were mapped to several signaling pathways including the regulation of membrane potential, calcium signaling, extracellular matrix, and phagocytosis. This is a retrograde signaling pathway from the mitochondria to the nucleus and is probably the result of changes in expression of several transcription factors, including key members of the NF-κB pathway. In conclusion, TSPO regulates nuclear gene expression through intracellular signaling. This is the first evidence of a compensatory response to the loss of TSPO with transcriptome changes at the cellular level.
