CONTRIBUTIONS TO SCIENCE
Prostate cancer: As prostate cancer onset and progression involves the mune system we developed a metastatic murine model that recapitulates human prostate cancer, both geneticaly and epigenetically, and metastasizes to bones and brain in the muse.. We demonstrated that in human prostate cancer cells the abundance of cyclin D1 is induced by growth factors and siRNA to cyclin D1 reduced ErbB2-mediated DNA synthesis in LNCaP cells (Cancer Research, 2007; 67(9):4364-4372)., that cyclin D1 restrains EMT and promotes stem cell expanding gene expression in the prostate. This may contribute to its strong prognostic value for poor outcome in biochemical-free recurrence in human prostate cancer (Cancer Research, 2014; Jan 15; 74(2):508-19).
Dach1 and Cancer. Dach1 was initially cloned as a gene governing eye development. Dr. Pestell has led in the field of Dach1 in tumorigenesis. Pestell was the first to show that Dach1 restrains tumor growth, that the abundance of Dach1 is reduced in human cancers and that Dach1 restrains stem cells through reprogramming an Oct/Nanog/EKLF pathway. He was the first to show Dach1 binds to non-canonical TF binding sites (c-Jun, Smad) and bind DNA directly to promote gene expression modules. He showed Dach1 is phosphorylated and acetylated and controls breast cancer epithelial cell growth and migration in vitro and in vivo.
Androgen and Nuclear receptor acetylation. Dr. Pestell was the first to show nuclear receptors including the androgen receptor, are acetylated, that acetylation regulates contact-independent growth, and that this event is rate-limiting in hormone signaling and that acetylation is a general mechanism conserved among diverse nuclear receptors regulating diverse biological processes. Dr. Pestell proved that a single residue acetylated in the nuclear receptor, converted a growth suppressor into a growth activator. There have been >19,300 publications on nuclear receptor acetylation since our original discovery.
Cancer Stem cells. The Pestell lab has defined the requirement for specific target genes in the formation of breast and prostate epithelial cancer stems cells using transgenic or inducible knockout mice (NFκB, p21CIP1, c-jun) and have defined distinct roles for cyclin D1 in polarity vs stem cell function. These transgenic animals have been shared widely with the research community.
Cyclin D1 non canonical functions governing gene expression. Dr. Pestell has been a pioneer in the understanding of cell-cycle control in cancer. He was the first to show that: 1) cyclins are direct transcriptional targets of oncogenic and tumor suppressor signals; 2) cyclin D1 expression is rate-limiting for oncogeneinduced breast tumor and colon growth in vivo; 3) cyclin D1 binds DNA to regulate gene expression and chromosomal instability; 4) cyclins interact with nuclear receptors and tumor suppressors; 5) cyclins regulate mitochondrial metabolism, cellular migration, the non-coding genome and its biogenesis;
