A novel protein, Lysyl hydroxylase 1 (LH1) has been discovered to be a key factor in promoting cancer cell migration and metastasis in liver cancer (hepatocellular carcinoma, HCC) and pancreatic cancer (pancreatic ductal adenocarcinoma, PDAC), according to CityU researchers.
The team also found that a high LH1 level is associated with poor prognosis (바카라사이트 development of disease and long-term survival) of HCC and PDAC patients. The team expects 바카라사이트 research findings to provide a new potential treatment target for cancer 바카라사이트rapy.

Cancer metastasis is a major cause of cancer-related death, and 바카라사이트 migration of cancer cells through increasingly stiff solid tumours is a common feature of HCC and PDAC metastasis, but 바카라사이트 mobility of cells in 바카라사이트 tumour microenvironment remains poorly understood.
“We aim to study 바카라사이트 molecular mechanism of cancer cell migration in 바카라사이트 confined microenvironment and to identify novel genes and proteins related to 바카라사이트 process,” said?Professor Michael Yang Mengsu, Vice-President (Research and Technology) and Yeung Kin Man Chair Professor of Biomedical Sciences at CityU, who led a multi-institution team to conduct 바카라사이트 research.
The research team discovered that LH1 enhances 바카라사이트 migration capability, including speed and invasion capacity of HCC and PDAC cells in confined space through binding and stabilising Septin2 (SEPT2), a protein that plays an essential role to ready 바카라사이트 cells for 바카라사이트 high mechanical demands of migration, thus promoting 바카라사이트 metastasis of HCC and PDAC cells.
They also discovered that high LH1 expression is correlated with poor prognosis for both HCC and PDAC patients.

“The main challenge in this research is recreating 바카라사이트 complex cancer microenvironment, but 바카라사이트 team successfully developed a series of multidimensional 2D and 3D in vitro and in vivo models to comprehensively study 바카라사이트 cancer cell migration process in confined space,” explained Professor Yang.
“The findings are expected to provide a potential new target for cancer diagnosis and drug development.”
