Genome-wide CRISPR-Cas9 knockout library screening identified PTPMT1 in cardiolipin synthesis is crucial to survival in hypoxia in liver cancer
Jan 26, 2021
Hypoxia, oxygen deprivation, is an important feature in solid tumors, especially liver cancer. Hypoxia is associated with tumor aggressiveness and therapy resistance. We performed genome-wide CRISPR-Cas9 library screening and identified PTPMT1, an important enzyme for cardiolipin (CL) synthesis, as a novel therapeutic target for survival of liver cancer cells under hypoxia. CL makes up the mitochondrial membrane where it stabilizes ETC complexes to prevent electron leakage and excessive ROS accumulation under hypoxia. Inhibition of PTPMT1 greatly induced oxidative stress and suppressed growth of not only liver cancer, but also other solid tumors.
This study was driven by our MPhil graduate Macus and Dr. Larry Wei in collaboration with Dr. Jack Wong's team. The study was recently published in Cell Reports. Congratulations Macus and Larry, amazing work!
Dr. KP Stephen Chang Gold Medal 2019/2020
Jan 11, 2021
Congratulations to Derek for being selected as the recipient of the Dr. KP Stephen Chang Gold Medal (Best PhD Thesis Award) from the Faculty of Medicine, HKU. His thesis title is "Adaptive and Constitutive Activations of Antioxidant-producing Metabolic Pathways in Hepatocellullar Carcinoma". In the past 4 years, he has discovered the major molecular mechanisms that lead to the metabolic alterations in the folate cycle and malate metabolism, generating NADPH which stabilizes antioxidant thioredoxin to allow liver cancer cells to overcome oxidative stress challenge. His work has led to the identification of novel therapeutic strategies that might potentially impede liver cancer progression.
We are very proud of you, Derek!
Tomorrow's Scientists Exploration Camp of the Hong Kong Laureate Forum
The inaugural Hong Kong Laureate Forum will take place on 15-20 Nov 2021. The forum has invited Shaw Laureates and renowned scientists to share their research and their journey in scientific explorations with 200 young scientists around the globe. This is going to be an exciting program with seminars, group discussions, workshops, and poster sessions.
To kick off, Tomorrow's Scientists Exploration Camp of the Hong Kong Laureate Forum has started on 5 Jan 2021. Due to COVID-19, our program was launched online. In this program, Carmen and Sean (Assistant Professor of Mathematics at Hong Kong Baptist University) have shared their experience with 60 local undergraduate students who are keen to pursue science and who will be selected to join the inaugural Hong Kong Laureate Forum. The participants have been very active with many questions. Due to the time constraint, we were not able to answer all questions. But, don't hesitate to contact us if you have more questions or doubts about your choice and directions.
We thank the council of the Hong Kong Laureate Forum for inviting us to be part of this meaningful event. It will be an exciting program. Stay tuned.

A new publication featured by editorial commentary in Gastroenterology!
Our latest work by David has been accepted for publication in Gastroenterology and was chosen as a featured article for editorial commentary!
Immune checkpoint inhibitor, PD-1 inhibitor, is only effective in a small percentage of liver cancer patients. Our work has uncovered a resistant mechanism to anti-PD-1 treatment. Using CyTOF, we found that another immune checkpoint, TIGIT, was induced by anti-PD-1 treatment. Liver cancer cells express PVRL1 which stabilizes PVR, the ligand for TIGIT to keep T cells exhausted even in the presence of anti-PD-1 treatment. We found that anti-TIGIT could sensitize tumors to anti-PD-1 treatment, providing the mechanistic rationale for combination therapies.

Congratulations to our mentor, Professor Gregg Semenza, for winning the Nobel Prize!
Professor Gregg Semenza is one of recipients of the Nobel Prize in Physiology or Medicine 2019 for his groundbreaking discovery of the oxygen sensing and adaptation system in mammalian cells. Oxygen is the most essential element in life. Professor Semenza discovered the key protein in the oxygen sensing system, hypoxia-inducible factor 1 (HIF-1), which enables cells to survive in low oxygen environment. His discovery has broad implications in the physiology and pathology of diseases including stroke and cancer.
Genome wide CRISPR-Cas9 KO screening identified an important metabolic pathway responsible for Sorafenib resistance.
Sorafenib is a standard therapy for advanced liver cancer patients. However, most patients develop resistance towards Sorafenib. Using the CRISPR-Cas9 knockout library screening platform, we identified that the serine synthesis pathway (SSP) as the major metabolic pathway that enables liver cancer cells to survive under Sorafenib treatment. PHGDH is the first committed enzyme of the SSP pathway that diverts glycolytic metabolites into the SSP. PHGDH inhibitor greatly sensitizes liver cancer cells to Sorafenib treatment and inhibits liver cancer growth in mice.
This joint work with Dr. Jack Wong's team has been recently published in Nature Communications. Congratulations to Larry for his publication!
Carmen has been elected as a member of the Hong Kong Young Academy of Sciences (YASHK).

FACT, histone chaperone, is responsible for NRF2-mediated transcription elongation
Our joint publication with Dr. Jack Wong's epigenetics lab has been accepted by GUT. NRF2 is known to be a transcription factor and the major regulator that helps cells to overcome oxidative stress by initiating transcription of a repertoire of antioxidant genes. How NRF2 activates this adaptive response in an expeditious manner to ensure liver cancer cells survive high oxidative stress?
In this work, we identified a histone chaperone, the FACT complex, is responsible for NRF2-mediated transcription elongation of antioxidant genes. NRF2 initiates transcription when liver cancer cells encounter oxidative stress. The FACT complex is stabilized by oxidative stress and is further induced by NRF2. With the FACT complex, nucleosome could be reassembled and disassembled quickly to allow RNA polymerase to pass through chromatin during elongation to accelerate antioxidant gene transcription. Excitingly, a FACT inhibitor, curaxin, is able to reverse the event and suppress liver cancer growth in our mouse model.
Congratulations to Jialing for her exciting finding being accepted for publication!

Carmen is going to give an oral presentation about the link of metabolic rewiring of cancer cells and immune components in liver cancer on September 15th, 2017.
Our paper integrating the knowledge of cancer metabolism and immunity is published in Nature Communications. Congratulations to David!
In this study, we found that hypoxic liver cancer cells express an ectoenzyme, ENTPD2, which converts extracellular ATP to AMP, thereby favoring the accumulation of myeloid-derived suppressor cells in the tumor microenvironment of liver cancer. This population of myeloid cells inhibit T cells, enabling the cancer cells to bypass immune surveillance. Excitingly, we found that ENTPD2 inhibitor improved the efficiency of anti-PD1 and anti-CTLA4 by unleashing T cells to combat HCC.
Our paper is published in JCI this month. Congratulations to Derek!
In this study, we identified folate cycle as a new metabolic vulnerability in liver cancer.
