Recurrent somatic mutations in the promoter region of telomerase reverse transcriptase (TERT) gene and in the exon 3 of CTNNB1 gene have been recognized as common events in hepatocellular carcinoma (HCC) with variable frequencies depending on etiology and geographical region.
Serum miRNA155 levels and blood and tissue hTERT mRNA were detected by real-time quantitative reverse-transcriptase PCR (RT-qPCR) among liver cirrhosis and HCC patients.
We found recurrent mutations in several genes such as telomerase reverse transcriptase (TERT; 65% of the total 104 HCCs), TP53 (38%), CTNNB1 (30%), AXIN1 (2%), PTEN (2%), and CDKN2A (2%).
In conclusion, these findings showed that combination HSV1-TK/hTERT gene therapy effectively and safely inhibits HCC cell growth in vitro and in vivo and is worthy of development in clinical trials for the treatment of HCC.
To circumvent side effects due to TERT expression in regenerating liver tissue, liver-specific microRNA-regulated ribozymes were constructed by incorporating complementary binding sites for the hepatocyte-selective microRNA-122a (miR-122a), which is down-regulated in HCC.
In our study, we tested a matrix metalloproteinase-2 (MPP2) aCPP in delivering hTERT siRNA into hepatocellular carcinoma cells (SMMC-7721) to silence the hTERT gene.
Telomerase reverse transcriptase (TERT), which encodes the catalytic subunit of telomerase, is highly expressed in a variety of invasive cancers, including HCC.
We aimed to evaluate the occurrence of telomerase reverse transcriptase (TERT) promoter mutations in the transformation of cirrhotic nodules into hepatocellular carcinoma (HCC).
Recently, rare loss-of-function mutations in Apolipoprotein B resulting in very low density lipoproteins hepatic retention and in Telomerase reverse transcriptase influencing cellular senescence have also been linked to HCC in NAFLD.
Furthermore, knockdown of human telomerase reverse transcriptase expression mitigated the hepatitis B virus core protein-enhanced hepatocellular carcinoma cell proliferation and clone formation in vitro.
Because the TERT activity is elevated in most cases of hepatocellular carcinoma (HCC), the current study aims to investigate whether Telomelysin can be used for treatment of HCC.
We also identified recurrent HBV integration events (in ≥ 4 HCCs) that were validated by RNA sequencing (RNA-seq) and Sanger sequencing at the known and putative cancer-related TERT, MLL4 and CCNE1 genes, which showed upregulated gene expression in tumor versus normal tissue.
