Abstract Bromodomain-containing protein 4 (BRD4) is overexpressed and functionally implicated in various myeloid malignancies. However, the role of BRD4 in normal hematopoiesis remains largely unknown. Here, utilizing an inducible Brd4 knockout mouse model, we find that deletion of Brd4 (Brd4Δ/Δ) in the hematopoietic system impairs hematopoietic stem cell (HSC) self-renewal and differentiation, which associates with cell cycle arrest and [...]Science Reports: Sex-dependent differences in the genomic profile of lingual sensory neurons in naïve and tongue-tumor bearing mice (Chen, Lai)

Tumanov, Zhao Lai, Korri Weldon, Yidong Chen & Shivani Ruparel Abstract Mechanisms of sex-dependent orofacial pain are widely understudied. A significant gap in knowledge exists about the comprehensive regulation of tissue-specific trigeminal sensory neurons in diseased states of both [...]Nucleic Acids Research: TLK1-Mediated RAD54 Phosphorylation Spatio-Temporally Regulates Homologous Recombination Repair (Chen, Sung)

Ishita Ghosh, Youngho Kwon, Aida Badamchi Shabestari, Rupesh Chikhale, Jing Chen, Claudia Wiese, Patrick Sung, Arrigo De Benedetti Abstract Environmental agents like ionizing radiation (IR) and chemotherapeutic drugs can cause severe damage to the DNA, often in the form of double-strand breaks (DSBs). Remaining unrepaired, DSBs can lead to chromosomal rearrangements and cell death. One major error-free pathway to repair DSBs is homologous [...]Bioinformatics Advances: DepLink: an R Shiny app to systematically link genetic and pharmacologic dependencies of cancer (Zheng, Houghton, & Chen Labs)

Tapsya Nayak, Li-Ju Wang, Michael Ning, Gabriela Rubannelsonkumar, Eric Jin, Siyuan Zheng, Peter J Houghton, Yufei Huang, Yu-Chiao Chiu, Yidong Chen Abstract Motivation Large-scale genetic and pharmacologic dependency maps are generated to reveal genetic vulnerabilities and drug sensitivities of cancer. However, user-friendly software is needed to link such maps systematically. Results Here, we present DepLink, a web server to identify genetic and pharmacologic perturbations [...]Nature: Structural Insights into BCDX2 Complex Function in Homologous Recombination (Sung Lab)
