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.

The team gathered for a nice all you can eat Japanese buffet to welcome our new PDF Chris and to bid farewell to our visiting student Huajian. Thank you Huajian for your hard work and contribution to the lab in the past year. We look forward to welcoming you back soon 🙂
Read about our research work on cancer stem cells – the roots of cancer. Thank you for the feature. Proud to be part of HKU 🙂 and one of the many women in science 🙂 🙂
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.

We welcome Yifei Wang (Research Assistant), Jia-Jian Loh (PhD student), Victoria Gao (PhD student) and Yunong Xie (Lab Intern) to the team! Lunch out on High Street at Sai Ying Pun.
Congrats to our most recent PhD graduate – Dr. Noelia Che! All the best to your new adventures at Oxford 🙂 Come visit us whenever you are back in town!
Stephanie was invited to speak at the NSFC-BHKAEC Joint Symposium on Chemistry for New Frontiers which took place in Hong Kong from 28-31 July 2019. Thank you for the opportunity!
