Journal of Biological Chemistry: The transcription factor Wilms tumor 1 confers resistance in myeloid leukemia cells against the proapoptotic therapeutic agent TRAIL (tumor necrosis factor α-related apoptosis-inducing ligand) by regulating the antiapoptotic protein Bcl-xL

September 21, 2012

Hima Bansal 1, Theresea Seifert, Carlos Bachier, Manjeet Rao, Gail Tomlinson, Swaminathan Padmanabhan Iyer, Sanjay Bansal Abstract Tumor necrosis factor α-related apoptosis-inducing ligand (TRAIL) is considered a promising cancer therapeutic agent due to its ability to induce apoptosis in a variety of cancer cells while sparing normal cells. However, many human tumors including acute myeloid leukemia (AML) are partially or completely resistant […]

Pediatric Blood & Cancer: Clinical, histologic, and genetic features of mesothelioma in a 7-year-old child

September 7, 2012

Aaron Sugalski 1, Mary Davis, Latha Prasannan, Victor Saldivar, Jaclyn Y Hung, Gail E Tomlinson Abstract Malignant mesothelioma (MM) is a highly aggressive malignancy that is extremely rare in children. This case report documents a 7-year-old male without previous asbestos exposure with peritoneal MM that initially responded to chemotherapy with cisplatin and gemcitabine but ultimately metastasized to his chest. He was […]

Journal of Clinical Investigation: ZEB1 drives prometastatic actin cytoskeletal remodeling by downregulating miR-34a expression

August 1, 2012

Young-Ho Ahn,1 Don L. Gibbons,1,2 Deepavali Chakravarti,3 Chad J. Creighton,4 Zain H. Rizvi,1 Henry P. Adams,5 Alexander Pertsemlidis,6 Philip A. Gregory,7,8 Josephine A. Wright,7,8 Gregory J. Goodall,7,8,9 Elsa R. Flores,3 and Jonathan M. Kurie1 Abstract Metastatic cancer is extremely difficult to treat, and the presence of metastases greatly reduces a cancer patient’s likelihood of long-term survival. The ZEB1 transcriptional repressor promotes metastasis through downregulation of microRNAs (miRs) […]

DNA Repair Protocols: Identification of Genes Required for Damage Survival Using a Cell-Based RNAi Screen Against the Drosophila Genome

July 23, 2012

Abstract Exposure to DNA-damaging agents invokes biological responses necessary for damage recovery and cell survival. Despite the presence of intact DNA repair pathways, a lack of certain other biological pathways has been shown to sensitize cells to DNA-damaging agents’ exposure. It is likely that following DNA damage a complex interplay between DNA repair pathways and […]

PLOS One: Androgen-Responsive MicroRNAs in Mouse Sertoli Cells

July 20, 2012

Subbarayalu Panneerdoss, Yao-Fu Chang, Kalyan C. Buddavarapu, Hung-I Harry Chen, Gunapala Shetty, Huizhen Wang, Yidong Chen, T. Rajendra Kumar, Manjeet K. Rao  Abstract Although decades of research have established that androgen is essential for spermatogenesis, androgen’s mechanism of action remains elusive. This is in part because only a few androgen-responsive genes have been definitively identified in the testis. Here, we propose that […]

Pediatric Blood & Cancer: Genetics and epigenetics of hepatoblastoma

July 13, 2012

Gail E Tomlinson 1, Roland Kappler Abstract A number of unique genetic features are observed in hepatoblastoma that has provided insights into the origins of hepatoblastoma. Hallmark cytogenetic changes in hepatoblastoma include the acquisition of additional copies of whole chromosomes and a recurring unbalanced translocation involving 1q. Genetic syndromes are associated with approximately 15% of hepatoblastoma and […]

IEEE: Evaluating Dynamic Effects of Copy Number Alterations on Gene Expression Using a Single Transcription Model

July 13, 2012

Fang-Han Hsu; Erchin Serpedin; Yidong Chen; Edward R. Dougherty Abstract: DNA copy number alterations (CNAs) are known to be related to genetic diseases, including cancer. The unlimited transcription (UT) model, in which transcription occurs permissively with a simple activation probability, has been proposed to investigate the long-term effects of CNAs on gene expression values. The queueing theory was […]

Transnational Cancer Research: Chain-reaction, a model of gene expression dynamics

June 21, 2012

Submitted May 21, 2012. Accepted for publication Jun 21, 2012. doi: 10.3978/j.issn.2218-676X.2012.06.01 One of the fundamental studies of transcription response to stimuli is to model the activation, repression of hundreds of genes, and their regulations. To further complicate the scenario, genes are regulated by multiple transcription factors, operating through different modes (earlier activation or secondary […]
