Objective:
The study aimed at elucidating the role of FOXD2-AS1 in facilitating the malignant progression of hepatocellular carcinoma (HCC) by regulating TWIST1.
Patients And Methods:
Relative levels of FOXD2-AS1 and TWIST1 in HCC tissues classified by tumor size and tumor node metastasis (TNM) staging were detected by quantitative Real-Time Polymerase Chain Reaction (qRT-PCR). The Kaplan-Meier method was applied to assess the prognostic potential of FOXD2-AS1 in HCC patients, followed by survival rate comparison using a log-rank test. After the knockdown of FOXD2-AS1 in HepG2 cells, the viability and migratory abilities were examined by Cell Counting Kit-8 (CCK-8) and transwell assay, respectively. The subcellular distribution of FOXD2-AS1 was detected. Finally, the involvement of TWIST1 in the regulation of HCC cell functions influenced by FOXD2-AS1 was explored.
Results:
FOXD2-AS1 was upregulated in HCC tissues, especially large tumor size or stage III-IV cases. High levels of FOXD2-AS1 predicted poor prognosis in HCC patients. FOXD2-AS1 was mainly distributed in the nucleus, and knockdown of FOXD2-AS1 weakened proliferative and migratory abilities in HepG2 cells. TWIST1 was upregulated in HCC tissues, which was positively correlated to FOXD2-AS1 level. The overexpression of TWIST1 could reverse the inhibited proliferative and migratory abilities in HepG2 cells with FOXD2-AS1 knockdown.
Conclusions:
FOXD2-AS1 facilitates the progression of HCC by upregulating TWIST1.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
