January 21, 2022

Shan Qi,  Javier Mota,  Siu-Hong Chan,  Johanna Villarreal,  Nan Dai,  Shailee Arya,  Robert A Hromas,  Manjeet K Rao,  Ivan R Corrêa Jr  Yogesh K Gupta  Abstract Methyltransferase like-3 (METTL3) and METTL14 complex transfer a methyl group from S-adenosyl-L-methionine to N6 amino group of adenosine bases in RNA (m6A) and DNA (m6dA). Emerging evidence highlights the role of [...]

Frontiers in Microbiology: Robust Heat Shock Response in Chlamydia Lacking a Typical Heat Shock Sigma Factor (Lai Lab)

January 20, 2022

Yehong Huang1,2†, Wurihan Wurihan2†, Bin Lu1,2†, Yi Zou3, Yuxuan Wang2†, Korri Weldon3, Joseph D. Fondell2†, Zhao Lai3,4, Xiang Wu1*†, and Huizhou Fan2*† Cells reprogram their transcriptome in response to stress, such as heat shock. In free-living bacteria, the transcriptomic reprogramming is mediated by increased DNA-binding activity of heat shock sigma factors and activation of genes normally repressed [...]

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 [...]
