Using mouse liver cancer models based on somatic genome editing to predict immune checkpoint inhibitor responses

November 28, 2022

Recently, our group has characterized tumors in precision mouse models with different genotypes into cold and hot tumor based on CD8+ T cell-infiltration level. This study provides proof-of-concept evidence to show that hot tumors are responsive to anti-PD-1 treatment while cold tumors are more suitable for combined treatment with anti-PD-1 and sorafenib. Our study might help to guide the design of patient stratification systems for single or combined treatments involving anti-PD-1. This study was recently published in Journal of Hepatology. Congratulations Vincent, David and Dicky on the elegant work!

Genome-Wide CRISPR/Cas9 Library Screening Revealed Dietary Restriction of Glutamine in Combination with Inhibition of Pyruvate Metabolism as Effective Liver Cancer Treatment

October 30, 2022

Recently, our group reported that pyruvate metabolism is crucial to HCC cells' adaptation of glutamine depletion using genome-wide CRISPR/Cas9 knockout library screening. In particular, we found that PDHA, PDHB or PC knockout induced metabolic reprogramming of the TCA cycle which disrupted mitochondrial function and suppressed HCC cell growth under glutamine depletion. In all, we identified pyruvate metabolism as targetable metabolic vulnerabilities for HCC treatment in combination with glutamine-deficient diet. This study was recently published in Advanced Science. Congratulations on the great work, Chunxue!

CFI-402257, a TTK inhibitor, effectively suppresses hepatocellular carcinoma

August 3, 2022

Another recent paper published by our group showed that another cell cycle inhibitor, CFI-402275, which specifically suppressed TTK which is responsible for spindle assembly checkpoint (SAC), caused chromosome mis-segregation and aneuploidy in liver cancer cells. CFI-402275, has different mechanism-of-action from CFI-400945, it also induced the STING-mediated SASPs in liver cancer cells through DNA damage and micronuclei formation. CyTOF study showed that CFI-402275 induced NK and CD8+ T cell recruitment. Combined treatment of CFI-402275 with anti-PD-1 extended the survival of mice with aggressive HCC. The work is published in PNAS. Congratulations to Dr. Cerise Chan!

Polo-like kinase 4 inhibitor CFI-400945 suppresses liver cancer through cell cycle perturbation and eliciting antitumor immunity

August 3, 2022

Our group has recently reported that an orally available and potent PLK4 inhibitor, CFI-400945, suppressed proliferating HCC cells by inhibiting centrosome duplication and promoting endoreplication. In addition to cell cycle inhibition, more interestingly, we found that CFI-400945 induced micronuclei formation, DNA damage, and cytosolic DNA which together induced the cytosolic DNA sensing pathway, the STING pathway, through cytosolic DNA sensor DDX41. STING activated NFKB and IRF3/7-mediated transcription of senescence-associated secretory phenotypes (SASPs) to drive the recruitment of various immune cells. We showed that CFI-400945 worked together with anti-PD-1 and anti-PD-L1 to suppress HCC growth. The work was recently published in Hepatology. Congratulations to Dr. Cerise Chan!

Genome-wide CRISPR-Cas9 knockout library screening identified PTPMT1 in cardiolipin synthesis is crucial to survival in hypoxia in liver cancer

January 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
January 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!

A new publication featured by editorial commentary in Gastroenterology!

August 27, 2020

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.

Welcome back, Lynna!

Congratulations to our mentor, Professor Gregg Semenza, for winning the Nobel Prize!

October 06, 2019

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.

October 14, 2019

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

September 07, 2019

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!

Histone chaperone FACT complex mediates oxidative stress response to promote liver cancer progression. Gut. 2019 Aug 22. pii: gutjnl-2019-318668. doi: 10.1136/gutjnl-2019-318668. [Epub ahead of print]

New metaboblic vulnerability in liver cancer

April 29, 2019

Recently, we found that liver cancer cells rely on the thioredoxin system to counteract oxidative stress. We also demonstrated that auranofin, an inhibitor that targets thioredoxin reductase 1 (TXNRD1) which is commonly used in arthritis, could be repurposed for liver cancer treatment as single treatment or as combined treatment with Sorafenib.

Congratulations to Derek for his new publication!

Induction of Oxidative Stress Through Inhibition of Thioredoxin Reductase 1 Is an Effective Therapeutic Approach for Hepatocellular Carcinoma. Hepatology. 2019 Apr;69(4):1768-1786. doi: 10.1002/hep.30467.

September 10, 2017

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!
