Targeting Transcriptional and Epigenetic Reprogramming in Stromal Cells in Fibrosis and Cancer

Cold Spring Harbor Symposia on Quantitative Biology
Nasun HahRonald M Evans

Abstract

The basis of many human diseases arises from both genetic and epigenetic regulation. Recent advances in the understanding of the mechanisms underlying transcriptional and epigenetic regulation and their prevalence as contributors to a diverse range of human diseases have led us to focus on transcription and epigenetic changes in a variety of human disease conditions. Specifically, our recent studies in liver fibrosis and pancreatic cancer have demonstrated that the epigenetic regulation in hepatic stellate cells (HSCs) and pancreatic stellate cells (PSCs) significantly contributes to the progress in such diseases and presents great therapeutic potential. We show that the vitamin D receptor (VDR) acts as a master genomic suppressor in both HSC and PSC activation. The studies also have demonstrated that the VDR ligand reduces fibrosis and inflammation in a murine liver fibrosis and pancreatitis model. Although our current studies focus on characterizing the roles of VDR and regulatory regions within gene promoters and regulatory enhancers, we have expanded our effort to epigenetic mechanisms as major determinants of gene activation and repression in order to develop potential therapeutics to modulate stroma-associated pathologies...Continue Reading

Cancer Metabolic Reprogramming (Keystone)

Cancer metabolic reprogramming is important for the rapid growth and proliferation of cancer cells. Cancer cells have the ability to change their metabolic demands depending on their environment, regulated by the activation of oncogenes or loss of tumor suppressor genes. Here is the latest research on cancer metabolic reprogramming.

Cancer Epigenetics & Metabolism (Keystone)

Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. The epigenetic changes may or may not provide advantages for the cancer cells. This feed focuses on the relationship between cell metabolism, epigenetics and tumor differentiation.

Cancer Epigenetics and Senescence (Keystone)

Epigenetic changes are present and dysregulated in many cancers, including DNA methylation, non-coding RNA segments and post-translational protein modifications. The epigenetic changes may be involved in regulating senescence in cancer cells. This feed captures the latest research on cancer epigenetics and senescence.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Cancer Genomics (Keystone)

Cancer genomics approaches employ high-throughput technologies to identify the complete catalog of somatic alterations that characterize the genome, transcriptome and epigenome of cohorts of tumor samples. Discover the latest research using such technologies in this feed.
