Starving advanced prostate cancer cells by pharmacological gluose deprivation with a resveratrol trimer trans-Gnetin H [TGH]

Project description:Prostate cancer is a unique disease from a metabolic perspective. Early stage localized prostate cancer does not typically display increased aerobic glycolysis (the Warburg effect), as seen in other malignancies. However, increasing evidence suggests that advanced prostate cancer exhibits the Warburg effect and displays high glucose uptake. We describe here that trans-gnetin H (TGH), a naturally-occurring resveratrol trimer extracted from Paeonia suffruticosa, displays significant anti-cancer effects in advanced prostate cancer cells in vitro. TGH perturbs energy metabolism by blocking the availability of glucose, inducing unfolded protein response (UPR) and C-MYC pathway downregulation in PC-3 cells. Our studies demonstrate the feasibility of targeting aerobic glucose metabolism in advanced prostate cancer and identify TGH as a potential therapeutic candidate.

C-MYC, a known driver oncogene in prostate cancer, is downregulated in TGH-treated cells. Our studies demonstrate the feasibility of targeting aerobic glucose metabolism in advanced prostate cancer and identify TGH as a potential therapeutic candidate.

Eaf7 identifies a native protein trimer linked to RNA polymerase-coupled nucleosome recycling

Project description:The NuA4 histone acetyltransferase (HAT) complex is required for gene specific regulation, cell cycle progression, and DNA repair. Dissection of the 13-subunit complex reveals that the Eaf7 subunit bridges Eaf5 with Eaf3, a H3K36me3-binding chromodomain protein, and this Eaf5/7/3 trimer is anchored to NuA4 through Eaf5. This subcomplex represents a functional module as deletions of these genes create similar phenotypes and a large portion of the trimer exists in a native form outside the NuA4 complex. Gene-specific and genome-wide location analyses indicate that the Eaf5/7/3 trimer correlates with transcription activity and is enriched over the coding region. In agreement with a role in transcription elongation, the Eaf5/7/3 trimer interacts with phosphorylated RNA polymerase II and helps its progression. In addition, loss of Eaf5/7/3 partially suppresses intragenic cryptic transcription arising in set2 mutant cells, suggesting a role in nucleosome destabilization. Such a function is supported by genetic interactions with the FACT histone chaperone. On the other hand, loss of the trimer leads to an increase of replication-independent histone exchange over the coding region of transcribed genes. Taken together, these results lead to a model where Eaf5/7/3 associates with elongating polymerase and is involved in the disassembly of nucleosomes in front of the polymerase, but also in their recycling in its wake.

Resveratrol action on A549 lung cancer cells

Project description:Resveratrol, a natural phytoestrogen found in red wine and a variety of plants, is reported to have protective effects against lung cancer, however there is very little work directed towards the understanding of the mechanism of action of resveratrol in lung cancer. In this study we used an experimental approach to understand the biological activity and molecular mechanisms of resveratrol in A549 lung cancer cells. Gene expression profiles were compiled using an oligonucleotide microarray to determine altered expression levels in resveratrol treated cells. Keywords: Genetic modification of A549 cells in response to resveratrol

Resveratrol Diet Aging (Heart, Liver, Muscle and Fat Tissue)

Project description:Resveratrol delays age-related deterioration and mimics transcriptional aspects of dietary restriction without extending lifespan A small molecule that safely mimics the ability of dietary restriction (DR) to delay age-related diseases in laboratory animals is greatly sought after. We and others have shown that resveratrol mimics effects of DR in lower organisms. In mice, we find that resveratrol induces gene expression patterns in multiple tissues that parallel those induced by DR and every-other-day feeding. Moreover, resveratrol-fed elderly mice shows a marked reduction in signs of aging including reduced albuminuria, decreased inflammation and apoptosis in the vascular endothelium, increased aortic elasticity, greater motor coordination, reduced cataract formation, and preserved bone mineral density. However, mice fed a standard diet did not live longer when treated with resveratrol beginning at mid-life. Our findings indicate that resveratrol treatment has a range of beneficial effects in mice but does not increase the longevity of ad libitum-fed animals when started mid-life.

Genome-wide analysis of Mtb-infected THP1 cells in response to resveratrol treatment

Project description:Analysis of resveratrol-treated cells at gene expression level. The hypothesis tested in the present study was that resveratrol can improve Mycobacterium tuberculosis (Mtb) treatment. Results provide important information of the host response to Mtb infection when given resveratrol, such as resveratrol-mediated modulation of inflammatory pathways induced upon infection.
