Nov 4-6 2019 @ Bad Nauheim, Germany – Stephanie gave a talk at the HKU-CUHK-GIBH-MPI Joint Symposium – New Frontiers in Stem Cell Biology at Max Planck Institute for Heart and Lung Research.
Read all about Steve’s REX1 story in the upcoming issue of Hepatology. In brief, the work describes a critical repressive function of REX1 in maintenance of HCC cells by regulating MKK6 binding and p38 MAPK signaling. REX1 deficiency induced enhancement of p38 MAPK signaling, leading to F-actin reorganization and activation of NRF2-mediated oxidative stress response, which collectively contributed to enhanced stemness and metastatic capabilites of HCC cells.

Our joint publication with Dr Terence Lee’s team is accepted for publication in Hepatology. Congrats to Carmen, Carol and the team!
In brief, our work found SHP2 blockade by SHP099 in combination with sorafenib attenuated the adaptive resistance to sorafenib by impeding RTK-induced reactivation of the MEK/ERK and AKT signalling pathways. SHP099 in combination with sorafenib may represent a novel and safe therapeutic strategy against HCC.

Congrats to Eric and the team on our latest paper published in Hepatology!
Our findings indicate that the PRMT6-ERK-PKM2 regulatory axis is an important determinant of the Warburg effect in HCC, and provide a mechanistic link among tumorigenicity, sorafenib resistance and glucose metabolism.Wong TL, Ng KY, Tan KV, Chan LH, Zhou L, Che N, Hoo RL, Lee TK, Richard S, Lo CM, Man K, Khong PL, Ma S.
