ARTICLE HIGHLIGHTS
Research background
Long noncoding RNAs, including Lnc524369, have the potential to regulate unknown cellular and molecular mechanisms in the initiation, progression, diagnosis, and prognosis of hepatocellular carcinoma (HCC). However, a critical gap in our knowledge is understanding how nucleus-enriched Lnc524369 promotes liver cancer growth.
Research motivation
To discover specific targets for the diagnosis and treatment of HCC.
Research objectives
To investigate the underlying mechanisms of Lnc524369 in HCC.
Research methods
The expression of Lnc524369, YWHAZ, and RAF1 was determined by qPCR or western blot. CCK-8, migration, and invasion assays were used to investigate Lnc524369 function. Forty-one HCC patients, the Cancer Cell Line Encyclopedia databases, STRING database, Human Protein Atlas database and the TCGA database were used for survival analysis.
Research results
Lnc524369 was significantly upregulated in the nucleus of HCC, which promoted the proliferation, migration, and invasion of liver cancer cells by upregulating YWHAZ and RAF1 expression. Lnc524369 and its downstream target YWHAZ/RAF1 protein could predict the poor overall survival time of HCC patients.
Research conclusions
The Lnc524369-mediated YWHAZ/RAF1 pathway is highly involved in the progression and prognosis of HCC.
Research perspectives
In the future, we will reveal the critical role of Lnc524369, which might enhance the early diagnosis of HCC and facilitate the further development of targeted therapy.
