Peripheral T Cells Ets-1 Maintains IL-7 Receptor Expression In
The Journal of Immunology Ets-1 Maintains IL-7 Receptor Expression in Peripheral T Cells Roland Grenningloh,*,† Tzong-Shyuan Tai,* Nicole Frahm,†,‡,1 Tomoyuki C. Hongo,‡ Adam T. Chicoine,‡ Christian Brander,†,‡,x,{ Daniel E. Kaufmann,†,‡,‖ and I-Cheng Ho*,† The expression of CD127, the IL-7–binding subunit of the IL-7 R, is tightly regulated during the development and activation of T cells and is reduced during chronic viral infection. However, the molecular mechanism regulating the dynamic expression of CD127 is still poorly understood. In this study, we report that the transcription factor Ets-1 is required for maintaining the expression of CD127 in murine peripheral T cells. Ets-1 binds to and activates the CD127 promoter, and its absence leads to reduced CD127 expression, attenuated IL-7 signaling, and impaired IL-7–dependent homeostatic proliferation of T cells. The expression of CD127 and Ets-1 is strongly correlated in human T cells. Both CD127 and Ets-1 expression are decreased in CD8+ T cells during HIV infection. In addition, HIV-associated loss of CD127 is only observed in Ets-1low effector memory and central memory but not in Ets-1high naive CD8+ T cells. Taken together, our data identify Ets-1 as a critical regulator of CD127 expression in T cells. The Journal of Immunology, 2011, 186: 969–976. nterleukin-7 signals are required for T cell development, GABPa or another Ets protein is responsible for maintaining maintaining the naive T cell pool, mounting proper primary CD127 expression in peripheral T cells is unknown.

Dissertation Advisor: Levi Garraway Terence Cheng Wong Integrated and Functional Genomic Approaches to Elucidate Differential Genetic Dependencies in Melanoma ABSTRACT Genomic characterization of human cancers over the past decade has generated comprehensive catalogues of genetic alterations in cancer genomes. Many of these genetic events result in molecular or cellular changes that drive cancer cell phenotypes. In melanoma, a majority of tumors harbor mutations in the BRAF gene, leading to activation of the MAPK pathway and tumor initiation. The development and use of drugs that target the mutant BRAF protein and the MAPK pathway have produced significant clinical benefit in melanoma patients. -

Fibroblast Growth Factor 12 Is Expressed in Spiral and Vestibular
www.nature.com/scientificreports OPEN Fibroblast growth factor 12 is expressed in spiral and vestibular ganglia and necessary for auditory Received: 5 February 2018 Accepted: 26 June 2018 and equilibrium function Published: xx xx xxxx Yukiko Hanada1,2, Yukiko Nakamura1, Yoshiyuki Ozono2, Yusuke Ishida1,3, Yasumitsu Takimoto1,2,4, Manabu Taniguchi5, Kazuya Ohata1,2, Yoshihisa Koyama1, Takao Imai2, Tetsuo Morihana2,6, Makoto Kondo1, Takashi Sato2, Hidenori Inohara2 & Shoichi Shimada1 We investigated fbroblast growth factor 12 (FGF12) as a transcript enriched in the inner ear by searching published cDNA library databases. FGF12 is a fbroblast growth factor homologous factor, a subset of the FGF superfamily. To date, its localisation and function in the inner ear have not been determined. Here, we show that FGF12 mRNA is localised in spiral ganglion neurons (SGNs) and the vestibular ganglion. We also show that FGF12 protein is localised in SGNs, the vestibular ganglion, and nerve fbres extending beneath hair cells. Moreover, we investigated FGF12 function in auditory and vestibular systems using Fgf12-knockout (FGF12-KO) mice generated with CRISPR/Cas9 technology. Our results show that the inner ear morphology of FGF12-KO mice is not signifcantly diferent compared with wild-type mice. However, FGF12-KO mice exhibited an increased hearing threshold, as measured by the auditory brainstem response, as well as defcits in rotarod and balance beam performance tests. These results suggest that FGF12 is necessary for normal auditory and equilibrium function. Hearing loss is a common problem in people of all ages. Te World Health Organization reports that 360 million people worldwide have hearing loss, with 32 million being children1. -
Agonists and Knockdown of Estrogen Receptor Β Differentially Affect
Schüler-Toprak et al. BMC Cancer (2016) 16:951 DOI 10.1186/s12885-016-2973-y RESEARCH ARTICLE Open Access Agonists and knockdown of estrogen receptor β differentially affect invasion of triple-negative breast cancer cells in vitro Susanne Schüler-Toprak1*, Julia Häring1, Elisabeth C. Inwald1, Christoph Moehle2, Olaf Ortmann1 and Oliver Treeck1 Abstract Background: Estrogen receptor β (ERβ) is expressed in the majority of invasive breast cancer cases, irrespective of their subtype, including triple-negative breast cancer (TNBC). Thus, ERβ might be a potential target for therapy of this challenging cancer type. In this in vitro study, we examined the role of ERβ in invasion of two triple-negative breast cancer cell lines. Methods: MDA-MB-231 and HS578T breast cancer cells were treated with the specific ERβ agonists ERB-041, WAY200070, Liquiritigenin and 3β-Adiol. Knockdown of ERβ expression was performed by means of siRNA transfection. Effects on cellular invasion were assessed in vitro by means of a modified Boyden chamber assay. Transcriptome analyses were performed using Affymetrix Human Gene 1.0 ST microarrays. Pathway and gene network analyses were performed by means of Genomatix and Ingenuity Pathway Analysis software. Results: Invasiveness of MBA-MB-231 and HS578T breast cancer cells decreased after treatment with ERβ agonists ERB-041 and WAY200070. Agonists Liquiritigenin and 3β-Adiol only reduced invasion of MDA-MB-231 cells. Knockdown of ERβ expression increased invasiveness of MDA-MB-231 cells about 3-fold. Transcriptome and pathway analyses revealed that ERβ knockdown led to activation of TGFβ signalling and induced expression of a network of genes with functions in extracellular matrix, tumor cell invasion and vitamin D3 metabolism. -
