Neuro-Oncology: Activation of WEE1 confers resistance to PI3K inhibition in glioblastoma

January 1, 2018

Shaofang Wu, Shuzhen Wang, Feng Gao, Luyuan Li, Siyuan Zheng, W K Alfred Yung, Dimpy Koul Abstract Background Oncogenic activation of phosphatidylinositol-3 kinase (PI3K) signaling plays a pivotal role in the development of glioblastoma (GBM). However, pharmacological inhibition of PI3K has so far not been therapeutically successful due to adaptive resistance through a rapid rewiring of cancer cell signaling. Here we […]

ACS Journals: Addressing late effects and quality of life essential to improving survivorship care (Aune Lab)

December 14, 2017

Abstract This news section offers Cancer readers timely information on events, public policy analysis, topical issues, and personalities. In this issue, we highlight efforts being made to improve cancer survivorship care and mitigate the late effects of cancer treatment. We also report on the increased risk for endocrine diseases among adolescent and young adult cancer survivors and […]

Genome Biology: The 3′ end of the story: deciphering combinatorial interactions that control mRNA fate.

November 29, 2017

Authors Penalva LOF Sanford JR Precise control of messenger RNA (mRNA) fate—its translation, stability, and localization—is required for accurate eukaryotic gene expression and is of fundamental importance to human health and disease. Initial efforts to determine how the cell controls these processes focused on “who done it?” We now understand that many of the clues […]

Pediatric Blood & Cancer: Evaluation of patritumab with or without erlotinib in combination with standard cytotoxic agents against pediatric sarcoma xenograft models

October 28, 2017

Abhik Bandyopadhyay 1, Edward Favours 1, Doris A Phelps 1, Vanessa Del Pozo 1, Samson Ghilu 1, Dias Kurmashev 1, Joel Michalek 2, Aron Trevino 2, Denis Guttridge 3, Cheryl London 4, Kenji Hirotani 5, Ling Zhang 5, Raushan T Kurmasheva 1, Peter J Houghton 1 Abstract Background: Integrating molecularly targeted agents with cytotoxic drugs used in the curative treatment of pediatric cancers is complex. An evaluation was undertaken with the ERBB3/Her3-specific antibody patritumab (P) either alone or with the ERBB1/epidermal growth factor […]

BMC Genomics: Genome-wide identification of key modulators of gene-gene interaction networks in breast cancer

October 3, 2017

Yu-Chiao Chiu, Li-Ju Wang, Tzu-Hung Hsiao, Eric Y. Chuang & Yidong Chen Abstract Background With the advances in high-throughput gene profiling technologies, a large volume of gene interaction maps has been constructed. A higher-level layer of gene-gene interaction, namely modulate gene interaction, is composed of gene pairs of which interaction strengths are modulated by (i.e., dependent on) the expression level […]

BMC Bioinformatics: XBSeq2: a fast and accurate quantification of differential expression and differential polyadenylation

October 3, 2017

Yuanhang Liu, Ping Wu, Jingqi Zhou, Teresa L. Johnson-Pais, Zhao Lai, Wasim H. Chowdhury, Ronald Rodriguez & Yidong Chen Abstract Background RNA sequencing (RNA-seq) is a high throughput technology that profiles gene expression in a genome-wide manner. RNA-seq has been mainly used for testing differential expression (DE) of transcripts between two conditions and has recently been used for testing differential alternative polyadenylation (APA). […]

JoVE: Genome-wide Analysis of HDAC Inhibitor-mediated Modulation of microRNAs and mRNAs in B Cells Induced to Undergo Class-switch DNA Recombination and Plasma Cell Differentiation

September 20, 2017

Helia N Sanchez 1, Tian Shen 2, Dawn Garcia 3, Zhao Lai 3, Paolo Casali 1, Hong Zan 4 Abstract Antibody responses are accomplished through several critical B cell-intrinsic processes, including somatic hypermutation (SHM), class-switch DNA recombination (CSR), and plasma cell differentiation. In recent years, epigenetic modifications or factors, such as histone deacetylation and microRNAs (miRNAs), have been shown to interact with B-cell genetic programs to […]

Nature Communications: Cross-talk between miR-471-5p and autophagy component proteins regulates LC3-associated phagocytosis (LAP) of apoptotic germ cells

September 19, 2017

Subbarayalu Panneerdoss, Suryavathi Viswanadhapalli, Nourhan Abdelfattah, Benjamin C. Onyeagucha, Santosh Timilsina, Tabrez A. Mohammad, Yidong Chen, Michael Drake, Kristiina Vuori, T. Rajendra Kumar & Manjeet K. Rao Abstract Phagocytic clearance of apoptotic germ cells by Sertoli cells is vital for germ cell development and differentiation. Here, using a tissue-specific miRNA transgenic mouse model, we show that interaction between miR-471-5p and autophagy member proteins regulates the clearance of […]

Oncotarget: Novel post-transcriptional and post-translational regulation of pro-apoptotic protein BOK and anti-apoptotic protein Mcl-1 determine the fate of breast cancer cells to survive or die
