  • Role of Estrogen Receptor Beta and the Isoflavone Genistein
    WCP2018 OR28-3 Oral session White-to-brown adipose differentiation: role of estrogen receptor beta and the isoflavone genistein Alessandra Bitto, Federica Mannino, Natasha Irrera, Giovanni Pallio, Domenica Altavilla, Francesco Squadrito Clinical and experimental medicine, University of Messina, Italy The two types of fat cells in mammals brown and white have different functions. White adipose tissue (WAT) stores excess energy in the form of triglyceride and releases free fatty acids during caloric deficiency. Brown adipose tissue (BAT) on the other hand can dissipate energy through thermogenesis. Genistein can have an effect on energy expenditure UCP (uncoupling protein) expression and protect against the obesogenic effect of a high calorie diet. The effect of genistein in inducing white-to-brown transdifferentiation was investigated in 3T3-L1 cells differentiated into white adipocytes with a specific medium (DMEM 10% calf serum 1% penicillin/streptomycin 500 uM 3isobutyl1 methylxanthine 10ug/ml insulin 250 nM dexmethasone 8 ug/ml biotin and 4 ug/ml pantothenic acid). Fully differentiated white adipocytes were treated after 10 days with different genistein doses (10-50-100-200 uM) for 24-48h or left untreated. Two specific ER-beta and PPAR-gamma receptor inhibitors were also used to understand if genistein effects are mediated by the estrogen or the PPAR receptor. Also a CRISPR/Cas9 approach was used to delete either ER-beta or PPAR-gamma to clarify which receptor is involved in genistein action. Intracellular lipid accumulation was determined by oil-red-O staining after 24 and 48hours of treatment. The expression of UCP1 estrogen receptor alpha and beta PPARalpha and gamma DIO2 (Type II iodothyronine deiodinase) PRDM16 (PR domain containing 16) and CIDEA (cell death inducing DNA fragmentation factor) were evaluated by qPCR after 24 and 48hours of genistein treatment.

  • Letters to the Editor
    LETTERS TO THE EDITOR The closely related rare and severe acute myeloid leukemias carrying EVI1 or PRDM16 rearrangements share singular biological features In a recent issue of Haematologica , Matsuo et al .1 pinpoint the pejorative effect of EVI1 overexpression in 18 acute myeloid leukemias (AML) with MLL rearrangements. However, EVI1 overexpression has also been reported in patients with translocations involving chromosome 3 and the EVI1 gene. 2,3 Because of the poor prognosis associated to these anomalies, it is important to investigate them at an early stage in order to adapt patient management. Indeed, previous reports 4-6 and the 2008 WHO classification 7 indi - cate that EVI1-rearranged (EVI1-r) AML display typical fea - tures, such as absence of thrombopenia, atypical megakary - Figure 1.

However, the genetic defects that drive the biology of these tumors remain largely unknown. In this study, analysis of micro- array gene expression signatures in adult T-ALL demonstrated a high prevalence of early immature leukemias and revealed a close relationship between these tumors and myeloid jem.rupress.org leukemias. Many adult immature T-ALLs harbored mutations in myeloid-specific oncogenes and tumor suppressors including IDH1, IDH2, DNMT3A, FLT3, and NRAS. Moreover, we identifiedETV6 mutations as a novel genetic lesion uniquely present in immature adult T-ALL. Our results demonstrate that early immature adult T-ALL represents a heterogeneous category of leukemias characterized by the presence of overlapping myeloid and T-ALL on May 30, 2015 characteristics, and highlight the potential role of ETV6 mutations in these tumors.

Kaestner2,4 & Katalin Susztak 1,2,4 1234567890():,; Determining the epigenetic program that generates unique cell types in the kidney is critical for understanding cell-type heterogeneity during tissue homeostasis and injury response. Here, we profile open chromatin and gene expression in developing and adult mouse kidneys at single cell resolution. We show critical reliance of gene expression on distal regulatory elements (enhancers). We reveal key cell type-specific transcription factors and major gene- regulatory circuits for kidney cells. Dynamic chromatin and expression changes during nephron progenitor differentiation demonstrates that podocyte commitment occurs early and is associated with sustained Foxl1 expression. Renal tubule cells follow a more complex differentiation, where Hfn4a is associated with proximal and Tfap2b with distal fate. Mapping single nucleotide variants associated with human kidney disease implicates critical cell types, developmental stages, genes, and regulatory mechanisms. The single cell multi-omics atlas reveals key chromatin remodeling events and gene expression dynamics associated with kidney development. 1 Renal, Electrolyte, and Hypertension Division, Department of Medicine, University of Pennsylvania, Perelman School of Medicine, Philadelphia, PA, USA. 2 Institute for Diabetes, Obesity, and Metabolism, University of Pennsylvania, Perelman School of Medicine, Philadelphia, PA, USA.

  • Interplay Between Cofactors and Transcription Factors in Hematopoiesis and Hematological Malignancies
    Signal Transduction and Targeted Therapy www.nature.com/sigtrans REVIEW ARTICLE OPEN Interplay between cofactors and transcription factors in hematopoiesis and hematological malignancies Zi Wang 1,2, Pan Wang2, Yanan Li2, Hongling Peng1, Yu Zhu2, Narla Mohandas3 and Jing Liu2 Hematopoiesis requires finely tuned regulation of gene expression at each stage of development. The regulation of gene transcription involves not only individual transcription factors (TFs) but also transcription complexes (TCs) composed of transcription factor(s) and multisubunit cofactors. In their normal compositions, TCs orchestrate lineage-specific patterns of gene expression and ensure the production of the correct proportions of individual cell lineages during hematopoiesis. The integration of posttranslational and conformational modifications in the chromatin landscape, nucleosomes, histones and interacting components via the cofactor–TF interplay is critical to optimal TF activity. Mutations or translocations of cofactor genes are expected to alter cofactor–TF interactions, which may be causative for the pathogenesis of various hematologic disorders. Blocking TF oncogenic activity in hematologic disorders through targeting cofactors in aberrant complexes has been an exciting therapeutic strategy. In this review, we summarize the current knowledge regarding the models and functions of cofactor–TF interplay in physiological hematopoiesis and highlight their implications in the etiology of hematological malignancies. This review presents a deep insight into the physiological and pathological implications of transcription machinery in the blood system.

Abstract PRDM16 is a member of the PRDM family of transcription co-regulators characterized by a PR domain (positive regulatory domain) that is similar to the SET domain found in lysine histone methyltransferases. Most PRDM proteins also contain one or more zinc finger domains that can confer direct DNA binding, in addition to other domains that mediate binding to additional transcription factors and cofactors. PRDM16 was originally identified from studies of (1;3)(p36;q21)-positive leukaemia’s but has subsequently been implicated in several developmental processes, including differentiation of muscle cell precursors into brown adipocyte fat cells. Such differentiation, regulated in part by the enzyme tyrosine-protein kinase-2 (Tyk2), has gained recent attention as a means to reduce obesity via manipulating the production of TYK2 and/or PRDM16.

  • Variations in Microrna-25 Expression Influence the Severity of Diabetic
    BASIC RESEARCH www.jasn.org Variations in MicroRNA-25 Expression Influence the Severity of Diabetic Kidney Disease † † † Yunshuang Liu,* Hongzhi Li,* Jieting Liu,* Pengfei Han, Xuefeng Li, He Bai,* Chunlei Zhang,* Xuelian Sun,* Yanjie Teng,* Yufei Zhang,* Xiaohuan Yuan,* Yanhui Chu,* and Binghai Zhao* *Heilongjiang Key Laboratory of Anti-Fibrosis Biotherapy, Medical Research Center, Heilongjiang, People’s Republic of China; and †Clinical Laboratory of Hong Qi Hospital, Mudanjiang Medical University, Heilongjiang, People’s Republic of China ABSTRACT Diabetic nephropathy is characterized by persistent albuminuria, progressive decline in GFR, and second- ary hypertension. MicroRNAs are dysregulated in diabetic nephropathy, but identification of the specific microRNAs involved remains incomplete. Here, we show that the peripheral blood from patients with diabetes and the kidneys of animals with type 1 or 2 diabetes have low levels of microRNA-25 (miR-25) compared with those of their nondiabetic counterparts. Furthermore, treatment with high glucose decreased the expression of miR-25 in cultured kidney cells. In db/db mice, systemic administration of an miR-25 agomir repressed glomerular fibrosis and reduced high BP. Notably, knockdown of miR-25 in normal mice by systemic administration of an miR-25 antagomir resulted in increased proteinuria, extracellular matrix accumulation, podocyte foot process effacement, and hypertension with renin-angiotensin system activation. However, excessive miR-25 did not cause kidney dysfunction in wild-type mice. RNA sequencing showed the alteration of miR-25 target genes in antagomir-treated mice, including the Ras-related gene CDC42. In vitro,cotrans- fection with the miR-25 antagomir repressed luciferase activity from a reporter construct containing the CDC42 39 untranslated region.
