Project description:Estrogen receptor alpha plays a critical role in breast cancer and is a major target in endocrine therapy. HIF-1 alpha have been associated with ER alpha and predict a worse outcome. Recent studies indicate that histone demethylase JMJD2B is a HIF-1 alpha target. However, little is known about the biological functions of JMJD2B, especially in breast cancer. To elucidate the mechanism by which JMJD2B reguates gene expression in normoxia and hypoxia, MCF-7 breast cancer cells were depleted forJMJD2B in normoxia and hypoxia. Our results provide insight into JMJD2B regulation of gene expression in breast cancer cells in normoxia and hypoxia. MCF7 cells were subjected to transfection with siRNA controls and two different siRNA oligos against JMJD2B for 24 hours. Cells were treated in normoxia and hypoxia for another 16 hours.

Project description:The Hypoxia-Inducible Factors induce the expression of the histone demethylases JMJD1A (KDM3A) and JMJD2B (KDM4B), linking the hypoxic tumor microenvironment to epigenetic mechanisms that may foster tumor progression. Using transcript profiling, we have identified genes that are regulated by JMJD1A and JMJD2B in both normoxic and hypoxic conditions in SKOV3ip.1 ovarian cancer cells. This dataset includes expression data obtained from exposing ovarian cancer cells to hypoxia in combination with siRNA-mediated knockdown of the hypoxia-inducible histone demethylases JMJD1A and JMJD2B. These data were used to both identify functional overlap between each histone demethylase, as well as identify effectors of tumor growth mediated by JMJD2B (KDM4B) in normoxia and hypoxia.

Project description:The Hypoxia-Inducible Factors induce the expression of the histone demethylases JMJD1A (KDM3A) and JMJD2B (KDM4B), linking the hypoxic tumor microenvironment to epigenetic mechanisms that may foster tumor progression. Using transcript profiling, we have identified genes that are regulated in RCC4 with siRNA-mediated knockdown of JMJD1A and JMJD2B. This dataset includes expression data obtained from renal cell Carcinoma being loss or mutation of the von Hippel-Lindau (VHL) tumor suppressor gene combination with siRNA-mediated knockdown of histone demethylases JMJD1A and JMJD2B.

Project description:In order to identify YBX1-dependent targets that are modulated under hypoxic conditions, we used control and YBX1 knockdown cells grown under normoxia and hypoxia to profile gene expression levels. Control and YBX1-knockdown cells were grown and profiled under hypoxia and normoxia to identify YBX1-dependent hypoxia-induced target transcripts.
