His work has implications for both therapeutic strategies and prognostic assessments in oncology.

Latest Patents

Xi Chen holds a patent titled "Modulation of breast cancer growth by modulation of XBP1 activity." This patent describes a previously unknown function of XBP1 in TNBC. It reveals that XBP1 is preferentially spliced and activated in TNBC, and that its deletion significantly blocks the growth of triple-negative breast tumors. Notably, XBP1 is essential for the self-renewal of breast tumor initiating cells (TICs). Furthermore, genome-wide mapping of the XBP1 transcriptional regulatory network has identified its fundamental role in regulating the response to hypoxia via the transcription factor hypoxia-inducible factor 1α (HIF1α). Importantly, the activation of this pathway carries prognostic implications, as the expression of the XBP1-dependent signature is associated with shorter survival times in human TNBC.

Career Highlights

Xi Chen is affiliated with Cornell University, where he conducts his research. His innovative work has garnered attention in the scientific community, contributing to advancements in cancer treatment and understanding.
