It was found to be overexpressed and to correlate with metastasis in patients with breast carcinoma (112), and was also associated with poor prognosis and chemoresistance in ovarian carcinoma (111). There as many as 22 potential alternative splicing sites in the TERT gene, but the function of many of them is unclear (164168). These two expression patterns appeared to be specific for many cancers, although some cancers exhibited variation between MAE and BAE in differed cell lines (34). Telomere dysfunction: a potential cancer predisposition factor. Cancer Res (2007) 67:194201.
In addition, these proteins are able to regulate TERT expression in tumor and normal cells (104). Nutrients. Moreover, MYC, a transcription activator, bound only to the hypomethylated mutated TERTp, resulting in monoallelic expression (MAE) in heterozygous cells (29). doi:10.3892/or.2014.3203, 112.

Regulatory Mechanisms of Human and Mouse Telomerase Reverse Transcriptase Gene Transcription: Distinct Dependency on c-Myc. Additionally, WT1 inhibited TERT transcription during differentiation. Furthermore, this inhibition of TERT could be possibly independent of other p53 functions, such as those associated with apoptosis (125).

MAD1 is recognized as an important cellular antagonist of c-MYC (117, 118). Incorporation of nucleoside analogues into newly synthesized telomeres impairs POT1 binding, causing telomere dysfunction that elicits a DNA damage response and cell death.

Cloning of human telomerase catalytic subunit (hTERT) gene promoter and identification of proximal core promoter sequences essential for transcriptional activation in immortalized and cancer cells. Aside from synthetic compound, various naturally occurring compounds, such as allicin (from garlic), curcumin (from turmeric), silibinin (from thistle), and epigallocathechin gallate (EGCG, from tea) were found to have telomerase inhibitory properties (202). Human telomerase reverse transcriptase (hTERT) is the most common tumor-associated antigen (TAA) and its activity is upregulated in more than 90% of cancers. This suggests that TERT rearrangement could be a critical step in cancer development. Seven STAT proteins have been identified as STAT 14, 5A, 5B, and 6 (105107). There are many differences between cancer cells and normal cells in noncancerous (benign) or cancerous (malignant) tumors. doi:10.1093/nar/28.13.2557, 138. Additionally, shuttling TERT out of the nucleus may be promoted by oxidative stress, and this mechanism is dependent on phosphorylation of tyrosine 707 by Src kinase. Other major TERT regulation mechanisms (also known as telomere maintenance mechanisms) are: chromosome rearrangements, methylation, miRNA interference, binding of transcription factors, genetic polymorphism, and alternative splicing. It functions by stimulating tumor-reactive CD8+ and CD4+ T-cell immunity specific for TERT (199, 207, 208). Coexpression of telomerase with oncogenes converts normal human cells into cells capable of tumorigenic growth (12, 13). 201. doi:10.1038/6010, 95.

However, development of telomerase inhibitors has been challenging and thus far there are no clinically approved strategies exploiting this cancer target. Using tissue microarrays from 611 breast carcinomas, this study has demonstrated that increased expression levels of Although these two techniques clearly differ in their sensitivity, these observations raise a note of caution in interpreting the results of telomerase assays, hTERT RT-PCR, and immunohistochemistry in tissue sections. Wu KJ, Grandori C, Amacker M, Simon-Vermot N, Polack A, Lingner J, et al. The site is secure.

As much as 1020% of total TERT is localized in mitochondria (176, 179). miRNAs binding to 3UTR generally silences the transcript, thus reducing gene expression.
