Cellular Oncology: Single-cell RNA profiling identifies diverse cellular responses to EWSR1/FLI1 down regulation in Ewing sarcoma cells (Houghton, Chen, Kitagawa, Ignatius)

January 12, 2022

Roxane Khoogar, Fuyang Li, Yidong Chen, Myron Ignatius, Elizabeth R. Lawlor, Katsumi Kitagawa, Tim H.-M. Huang, Doris A. Phelps & Peter J. Houghton Background The EWSR1/FLI1 gene fusion is the most common rearrangement leading to cell transformation in Ewing sarcoma (ES). Previous studies have indicated that expression at the cellular level is heterogeneous and that levels [...]

Genes & Cancer: EZH2 suppresses endogenous retroviruses and an interferon response in cancers (Shiio Lab)

January 10, 2022

Panneerselvam Jayabal1, Xiuye Ma1 and Yuzuru Shiio1,2,3 ABSTRACT Ewing sarcoma is an aggressive cancer of the bone and soft tissue in children. It is characterized by the chromosomal translocation between EWS and an Ets family transcription factor, most commonly FLI1. We recently reported that Ewing sarcoma depends on the autocrine signaling mediated by a cytokine, NELL2. [...]

PMC: The Role of Hedgehog Pathway in Uterine Leiomyosarcoma (Houghton Lab)

January 7, 2022

Natalia Garcia,1 Mara Ulin,2 Ayman Al-Hendy,3 and Qiwei Yang3 DESCRIPTION The uterine Leiomyosarcoma (LMS) represents 3%-7% of all uterine cancers. This rare tumor has an annual incidence of 0.8 per 100,00 women. Unfortunately, LMS is well known for its poor prognosis due to its high recurrence rate and resistance to the currently available treatment options. These features open the [...]

ASM Journals: GRWD1-WDR5-MLL2 Epigenetic Complex Mediates H3K4me3 Mark and Is Essential for Kaposi’s Sarcoma-Associated Herpesvirus-Induced Cellular Transformation (Lai)

January 5, 2022

Shan Wei, Songjian Lu, Lifan Liang, Xian Wang, Wan Li, Tingting Li, Luping Chen, , Enguo Ju, Xinquan Zhang, Zhao Lai, Yufei Huang, Xinghua Lu, Shou-Jiang Gao  ABSTRACT Infection by Kaposi’s sarcoma-associated herpesvirus (KSHV) is causally associated with numerous cancers. The mechanism of KSHV-induced oncogenesis remains unclear. By performing a CRISPR-Cas9 screening in a model of KSHV-induced cellular transformation of primary cells, we identified epigenetic regulators that were essential for KSHV-induced cellular transformation. Examination of TCGA data sets of the [...]

Briefings in Bioinformatics: Deep learning tackles single-cell analysis—a survey of deep learning for scRNA-seq analysis (Chen Lab)

January 4, 2022

        Mario Flores, Zhentao Liu, Tinghe Zhang, Md Musaddaqui Hasib, Yu-Chiao Chiu, Zhenqing Ye, Karla Paniagua, Sumin Jo, Jianqiu Zhang, Shou-Jiang Gao, Yu-Fang Jin, Yidong Chen, Yufei Huang Abstract Since its selection as the method of the year in 2013, single-cell technologies have become mature enough to provide answers to complex research questions. With the growth of single-cell profiling technologies, there has also [...]
