Estrogen receptor alpha (ERα) is implicated in the initiation and progression of breast cancer and its transcription depends on the modulation of epigenetic changes at target gene promoters via coregulators. There is a critical need to understand the molecular mechanism(s) by which deregulation of epigenetic changes occurs during breast cancer progression.(More)
Proline-, glutamic acid- and leucine-rich protein-1 (PELP1) is a scaffolding oncogenic protein that functions as a coregulator for a number of nuclear receptors. p53 is an important transcription factor and tumor suppressor that has a critical role in DNA damage response (DDR) including cell cycle arrest, repair or apoptosis. In this study, we found an(More)
A differential protein display screen resulted in the identification of a 27-kDa protein which strongly accumulates during the senescence of Podospora anserina cultures grown under standard conditions. After partial determination of the amino-acid sequence by mass-spectrometry analysis of trypsin-generated fragments, pairs of degenerated primers were(More)
The estrogen receptor (ER) co-regulator proline glutamic acid and leucine-rich protein 1 (PELP1) is a proto-oncogene that modulates epigenetic changes on ER target gene promoters via interactions with lysine-specific histone demethylase 1 (KDM1). In this study, we assessed the therapeutic potential of targeting the PELP1-KDM1 axis in vivo using liposomal(More)
Fistula in ano is a common malady in infancy. However, relatively little literature is devoted to it. Our aim was to describe the natural history and identify predictors of which children will ultimately recur. A retrospective review of patients less than 3 years old undergoing anal fistulotomy was performed between May 2002 and November 2007 at a tertiary(More)
Estrogen receptor (ERα) signaling plays a key role in hormonal cancer progression. ERα is a ligand-dependent transcription factor that modulates gene transcription via recruitment to the target gene chromatin. Emerging evidence suggests that ERα signaling has the potential to contribute to epigenetic changes. Estrogen stimulation is shown to induce several(More)
Proline-, glutamic acid-, and leucine-rich protein 1 (PELP1) is a proto-oncogene that functions as coactivator of the estrogen receptor and is an independent prognostic predictor of shorter survival of breast cancer patients. The dysregulation of PELP1 in breast cancer has been implicated in oncogenesis, metastasis, and therapy resistance. Although several(More)
Drosophila adults, when placed into a novel open-field arena, initially exhibit an elevated level of activity followed by a reduced stable level of spontaneous activity and spend a majority of time near the arena edge, executing motions along the walls. In order to determine the environmental features that are responsible for the initial high activity and(More)
The estrogen receptor (ERa) is implicated in the progression of breast cancer. Hormonal therapies which block ER functions or local and systemic estrogen production are currently used to treat ERa positive breast cancer. Hormonal therapy shows beneficial effects, however, initial or acquired resistance to endocrine therapies frequently occurs, and tumors(More)
Estrogen receptor (ERα) plays an important role in the initiation and progression of breast cancer. Many breast cancer patients respond positively to hormonal therapy; however, initial or acquired resistance to endocrine therapies frequently occurs and tumors recur as metastases. Emerging evidence suggests that ERα action is complex and involves functional(More)
