The pseudoknot is also critically important for the action of telomerase. The protein component of telomerase, telomerase reverse transcriptase (TERT), is indeed a protein enzyme and its amino acid sequence includes reverse transcriptase motifs. Epub 2011 Jul 23. Federal government websites often end in .gov or .mil. Urol Oncol. 1). Kras mutations-induced lung tumorigenesis and chemoresistance are attenuated by telomerase inhibition. Bethesda, MD 20894, Web Policies For these immunostaining experiments, we used proteins that are known to accumulate in DNA damage foci at sites of DNA damage, such as the protein hRif1. Gupta N, Patel HD, Taylor J, Borin JF, Jacobsohn K, Kenfield SA, Eggener SE, Price C, Davuluri M, Byrne N, Bivalacqua TJ, Loeb S. Prostate Cancer Prostatic Dis. Telomerase activity in hematopoietic cells is associated with self-renewal potential. Researchers found that the enzyme telomerase, which is active in most tumor cells, may also protect healthy adult cells from becoming cancerous. 2015;65:87108. Their telomeres are mostly maintained at a rather short length; the 40 kb telomeres in LOX melanoma cells are the exception rather than the rule. Kim MM, Rivera MA, Botchkina IL, Shalaby R, Thor AD, Blackburn EH. Immunotherapies, MeSH Alternatively, oligonucleotides complementary to the TERC template region can act as competitive telomerase inhibitors. Clipboard, Search History, and several other advanced features are temporarily unavailable. Gene Dev. We were able to show that this also occurs in vivo.

Sunaga N, Kaira K, Imai H, Shimizu K, Nakano T, Shames DS, Girard L, Soh J, Sato M, Iwasaki Y, Ishizuka T, Gazdar AF, Minna JD, Mori M. Oncogene. Ashwagandha root extract increased telomerase activity with highest enhancement of ~45% at 10 - 50 g concentration. However, blocking telomerase activity could affect cells where telomerase activity is . 2023 Jan;28(1):242-255. doi: 10.1038/s41380-022-01680-x. Federal government websites often end in .gov or .mil. Xu L, Blackburn EH. PMC Apoptosis was quantified in clonal lines stably expressing low levels of a mutant-template telomerase RNA construct, a control wild-type RNA construct, or parental MCF-7 cells. Integrin V, which has been implicated in promoting tumor metastasis, was also suppressed. Satisfied that the effects indeed resulted specifically from knockdown of the intended telomerase RNA, we analyzed the effects in multiple cell lines. As shortened telomeres inhibit tumor formation and prolong life span in a KrasG12D mouse lung cancer model, we investigated the implications of telomerase in Kras-mutant NSCLC. DNA methylation of the TERT promoter and its impact on human cancer. Such a phospho-profile, termed profile II, cannot fully respond to DNA damage; accumulated p53 remains inactive and does not trigger transcription of its target genes upon stimulus, as compared to the standard phospho-profile I. Bethesda, MD 20894, Web Policies scientists may be able to stop cancer progression and potentially increase mortality. J. Mol. 2022 Oct 30;10(11):2755. doi: 10.3390/biomedicines10112755. Valdiani A, Ofoghi H, Akbarizare M, Talei D. 3 Biotech. For example, we could reinfect those outgrowing cells and recapitulate the same growth kinetics compared with the controls for at least three cycles of reinfections. Lower left, schematic of the uncapping of telomeres. and transmitted securely. Telomere shortening is counteracted by the cellular enzyme telomerase. We therefore investigated what happens when you knock down the high levels of telomerase in human cancer cells. Tumor cells in control . Background: However, the RNA is also critically important to the enzyme action, and not only because it provides the template. PMC These applications include inhibiting or targeting telomerase as a novel antineoplastic strategy and using cells immortalized by telomerase for therapeutic applications. Would you like email updates of new search results? Kras mutations upregulate TERT expression, Figure 1. Would you like email updates of new search results? Structural and Functional Changes in Aging Kidneys. government site. An important conclusion of this work is that telomerase participates in cell responses in ways that do not seem to involve the telomere itself. Bookshelf That property also makes telomerase a very unusual reverse transcriptase. Bodnar AG, Ouellette M, Frolkis M, et al. 230000001965 increased Effects 0.000 claims description 18; 201000005787 hematologic cancer Diseases 0.000 claims description 14; Telomerase inhibitor BIBR1532 inhibits Kras mutations-induced cell transformation and migration capability, Figure 4. "Inhibition of Telomerase activity in human cancer cells by RNA interference". Telomeres and telomerase play an important role in human aging and cancer from the beginning of life till the very end. How do you increase telomerase? Granger et al. 8600 Rockville Pike Instead, the affinity was increased by almost 3-fold as shown by the em K /em M values for the L-cysteine analog, RD-PNB (29 2.2 M) Mephenesin compared to the D-cysteine analog, L-70 (11 0.9 M). The accumulation of oxidative DNA base damage can severely disrupt the integrity of the genome and is strongly associated with the development of cancer. Comprehensive lifestyle changes significantly increase telomerase activity and consequently telomere maintenance capacity in human immune-system cells. Maciejewska N, Olszewski M, Jurasz J, Baginski M, Stasevych M, Zvarych V, Folini M, Zaffaroni N. Cell Death Dis. In control cells, the wild-type telomerase RNA was introduced, and big robust tumors formed. 2019 Jun;9(2):219-230. doi: 10.15171/apb.2019.025. Bahcall M, Awad MM, Sholl LM, Wilson FH, Xu M, Wang S, Palakurthi S, Choi J, Ivanova EV, Leonardi GC, Ulrich BC, Paweletz CP, Kirschmeier PT, Watanabe M, Baba H, Nishino M, Nagy RJ, Lanman RB, Capelletti M, Chambers ES, Redig AJ, VanderLaan PA, Costa DB, Imamura Y, Jnne PA. Clin Cancer Res. Thus, telomerase represents an attractive target for highly selective cancer therapeutics. Telomeres are protective DNA-protein complexes at the end of linear chromosomes that promote chromosomal stability. Ornish et al (2008) investigated for three months the comprehensive lifestyle changes for 30 men with biopsy-diagnosed low-risk prostate cancer, which led to a significant increase in telomerase activity by 10%. Similar findings were also made in the setting of a simple xenograft model: When we xenografted human cancer cells expressing the mutant-template telomerase RNA into a mouse model, we saw greatly decreased tumor growth and some regression of the tumors, accompanied by high rates of apoptosis in the tumors (5). As a result, cancer cells essentially become immortal. Resulting in the overall . Telomere terminal transferase (telomerase) enzyme activity (not the identification of the genes encoding the components of telomerase) was discovered in 1985 in the single-cell organism Tetrahymena ().Almost a decade later, telomerase was described as an almost universal marker in advanced human cancers (), but it was not until 1997 that the catalytic protein component was isolated, first in . HHS Vulnerability Disclosure, Help We interpret these findings to mean that as the cells grew, with some probability they would die by apoptosis. Epub 2022 Jul 15. Here we discuss recent efforts targeting telomerase, including immunotherapies and direct telomerase inhibitors, as well as emerging approaches such as targeting TERT gene expression driven by TERT promoter mutations. Recent studies also suggest that telomerase is implicated in tumor . 30 men with biopsy-diagnosed low-risk prostate cancer were asked to make comprehensive lifestyle changes. An update. [The 2009 Nobel Prize in Medicine and its surprising message: lifestyle is associated with telomerase activity]. doi: 10.1016/j.chembiol.2022.09.002. Thus, Ashwagandha root extract has the anti-aging inducing potential. FOIA Targeting KRAS in NSCLC: Old Failures and New Options for "Non-G12c" Patients. Comprehensive lifestyle changes significantly increase telomerase activity and consequently telomere maintenance capacity in human immune-system cells. Epel ES, Lin J, Wilhelm FH, Wolkowitz OM, Cawthon R, Adler NE, Dolbier C, Mendes WB, Blackburn EH. These findings suggest that telomerase activity may affect telomere maintenance, thereby contributing to susceptibility to lung cancer. Telomerase inhibitor BIBR1532 prevents Kras, Figure 5. 2). The regulation of telomerase activity in human cells plays a significant role in the development of cancer. . Hence, our attempts to intervene in telomerase action have led us unexpectedly down a new avenue in which we find telomerase doing things that we never expected to see. To detect telomerase, a novel surface-enhanced Raman scattering (SERS) biosensor was constructed using the dual DNA-catalyzed amplification strategy composed of strand displacement amplification (SDA . They hypothesized that this region was key to regulating telomerase activity and began to experiment on melanoma cells. An official website of the United States government. These proteins include DNA sequencespecific binding proteins and other proteins that together, in effect, sheathe the chromosome end. DNA Southern blot experiments, done to examine the length of the telomeric DNA, showed that there was no bulk shortening of the telomeres. And, indeed, many labs and many groups have now shown that the apparent increase in telomerase is a common feature of human tumor cells. 2006 Apr;31(3):277-87. doi: 10.1016/j.psyneuen.2005.08.011. 2002 Nov;17(6):539-50. doi: 10.1093/mutage/17.6.539. Given this finding and the pilot nature of this study, we report these increases in telomerase activity as a significant association rather than inferring causation. (4) showed in a sufficiency experiment that forced ectopic overexpression of telomerase is sufficient to overcome cellular senescence in culture and maintain the telomeres at a steady length as cells continue to divide. Exp Cell Res. The telomerase RNA of mouse melanoma cells (B16 cells) was targeted using ribozymes, and the human telomerase RNA in human melanoma cells was targeted using the siRNA approach described previously (8). We also address some of the challenges to telomerase-directed therapies including potential therapeutic resistance and considerations for future therapeutic applications and translation into the clinical setting. MeSH . Importantly, BIBR1532 sensitized oncogenic Kras expressing Calu-3 cells to chemotherapeutic agents. Telomerase inhibitor BIBR1532 prevents Kras G12D -Calu-3 xenograft tumor growth and increases the, Figure 6. We aimed to assess whether 3 months of intensive lifestyle changes increased telomerase activity in peripheral blood mononuclear cells (PBMC). The ciliated protozoan Tetrahymena thermophila normally has constitutive telomerase and can continue to proliferate indefinitely like a cancer cell. The telomere, after all, represents a DNA end, which is at the end of the linear chromosomal DNA, but it has to be treated in a different way from an accidental DNA break in a chromosome. government site. Furthermore, the underlying DNA is also dynamic, for two reasons. The .gov means its official. Telomerase inhibitor BIBR1532 inhibits Kras, Figure 3. That sequence tract provides a molecular scaffold on which binds a set of proteins, about which much is known. 2013;14:205214. Telomerase activity was significantly lower in the lung cancer patients than in controls (mean standard deviation; 1.32 1.65 vs 2.60 3.09, P < 1 10(-4)). Telomerase is tightly repressed in the vast majority of normal human somatic cells but becomes activated during cellular immortalization and in cancers. Like an aglet, the telomere prevents that end from fraying away. Clipboard, Search History, and several other advanced features are temporarily unavailable. BioDrugs.

Various lines of evidence showed that the cells that grew out were those that either did not receive the lentivector or failed to overexpress the mutant-template telomerase RNA. Supporting this model, Shang Li, in collaboration with Chris Haqq and his group at University of California, San Francisco, showed that global gene expression profile changed within 4 days after the telomerase RNA was knocked down. In humans, gradual shortening of telomeres is observed throughout life in many cell types in every part of the body although the cells have a low level of telomerase. Aquilanti E, Kageler L, Wen PY, Meyerson M. Neuro Oncol. In collaboration with Mohammed Kashani-Sabet and his group at University of California, San Francisco, we examined the effect of telomerase RNA knockdown on metastasis in two in vivo models. 2021 Dec 23;11:792385. doi: 10.3389/fonc.2021.792385. Carol Greider and I identified the telomerase enzyme first in the ciliated protozoan Tetrahymena. The primary endpoint was telomerase enzymatic activity per viable cell, measured at . This was first shown in a model organism, the ciliate Tetrahymena, and subsequently in many other organisms. Hence, the DNA at the ends of the chromosomes was effectively naked. In the context of cancer cells, particularly those that are well on the way to a malignant state, telomerase has cancer-promoting properties. The mutant-template telomerase RNA caused uncapping of the telomeres. official website and that any information you provide is encrypted Telomerase inhibitor BIBR1532 shortens telomere length and suppresses mutant Kras-induced cell long-term proliferation, Figure 3. Given this finding and the pilot nature of this study, we report these increases in telomerase activity as a significant association rather than inferring causation. it was more than a decade ago that researchers showed that TPP1 would increase telomerase activity. In the current work, we investigated the relationship between genetically predicted LTL and lung . Although in many normal adult human cell types telomerase is often expressed at very low, sometimes undetectable, levels, it is clear that telomerase has some protective role in such normal cells. Telomerase, the enzyme that reduces telomere shortening in certain cells, is reactivated or increased in more than 90 percent of cancers, found a 2016 study. The first way of intervening in telomerase action in human cancer cells exploited the fact that the telomeric DNA makes the molecular scaffold for the binding of telomere-protective proteins, which include DNA sequencespecific binding proteins. Larger randomised controlled trials are warranted to confirm the findings of . We did these experiments in a manner that made the test of the effects as stringent as possible because we did not include a drug selection step after infecting the cells with the lentiviral vectors. Before We have evaluated the association between telomerase activity and the risk of lung cancer in peripheral blood. Kras mutations upregulate TERT expression and telomerase activities by the RAS-MEK pathway, Figure 2. Epub 2013 Sep 17. The team discovered that BRG1 and TPP1 interact to promote TERT-driven telomerase activity. signals of methylene blue (MB) catalyzed by well monodisperse Au nanorods (AuNRs). Telomerase is a critical factor in CAR-T cell replication and overall function, and its abundance diminishes in cell division, aging, and disease.With reduced telomerase activity, CAR-T cells typically die or become aged, non-functional, and non-proliferating (senescent), leading to inhibited CAR-T function and a lack of prolonged cancer . When telomerase activity was categorized into quartiles based on telomerase activity in the controls, the risk of lung cancer increased as telomerase activity reduced (P(trend) = 1 10(-4)). Curiously, however, the high level of telomerase in the majority of cancer cellswhich is typically a couple of orders of magnitude higher in cancer cells than in the differentiated normal cells around itusually does not lead to the cancer cells having long telomeres. Jang JS, Choi YY, Lee WK, Choi JE, Cha SI, Kim YJ, Kim CH, Kam S, Jung TH, Park JY. The site is secure. official website and that any information you provide is encrypted Similar to astragalus, extracts of cycloastragenol can increase telomerase activity. 8600 Rockville Pike GFP lane, Northern blot analysis of RNA from cells expressing GFP alone from the control lentiviral vector [adapted from Li et al. DNA glycosylase is the critical enzyme that initiates the base excision repair (BER) pathway, recognizing and excising damaged bases. The activity of telomerase is relatively low in somatic cells and absent in normal cells, . Increased telomerase activity was associated with a decrease in the level of low-density lipoprotein cholesterol (LDL) and a decrease . -cancer cells show decreased telomerase activity and the telomeres are shortened. Effect of comprehensive lifestyle changes on telomerase activity and telomere length in men with biopsy-proven low-risk prostate cancer: 5-year follow-up of a descriptive pilot study. While increased telomerase activity could bring youth to aging cells and cure premature aging-like diseases, too much of a good thing can be damaging for the individual. Before While telomerase activity is detected in cells with high proliferation potential, in somatic cells it is virtually undetected resulting in the overall shortening of telomeres with each cell division. An official website of the United States government. 2021 Dec 1;23(12):2004-2013. doi: 10.1093/neuonc/noab203. 2022 Nov 7;10:1060201. doi: 10.3389/fcell.2022.1060201. Keshavarz M, Xie K, Schaaf K, Bano D, Ehninger D. Mol Psychiatry. Progressing next generation of telomere-targeting candidates through proof of concept studies with promising anti-cancer activity Filed provisional new composition of matter patent during fourth . Another study from the same group further clarified this potential link between telomerase expression and myofibroblast differentiation (18); using the same bleomycin-induced pulmonary fibrosis rat model, they demonstrated that the inhibition of fibroblast telomerase activity led to increased -SMA expression, which represents a marker of . Genetic Variants of the TERT Gene and Telomere Length in Obstructive Sleep Apnea. The p53 response pathway is commonly abrogated in human cancers. Telomere shortness in human beings is emerging as a prognostic marker of disease risk, progression, and premature mortality in many types of cancer, including breast, prostate, colorectal, bladder, head and neck, lung, and renal cell. Careers. government site. Kenessey I, Ki K, Horvth O, Cserepes M, Molnr D, Izsk V, Dobos J, Hegeds B, Tvri J, Tmr J. Oncotarget. Methods: CHICAGO--(BUSINESS WIRE)-- MAIA Biotechnology, Inc. (NYSE American: MAIA) announced today the advancement of its Telomere-Targeting Molecule Program ("Project T3").MAIA is designing and evaluating multiple telomere-targeting compounds designed to modify the telomeric structure through the cancer cell - intrinsic telomerase activity - and thus cause the death of these cells. Telomerase activity has been detected in 85% of tumors representing 15 cancer types, whereas most benign tumors and somatic tissues have very low levels or lack detectable telomerase activity Furthermore, in special metastatic tumor types such as neuroblastoma stage IVs, in which there is a high rate of spontaneous regression, telomerase . We chose as examples for study two mutant-template telomerase RNAs, which were mutated in such a way that they dictated the synthesis of DNA that would be unable to bind the sequence-specific telomere-protective proteins. Epub 2013 May 5. Curr Cancer Drug Targets. Targeting telomeres: advances in telomere maintenance mechanism-specific cancer therapies. Melanoma, an aggressive form of skin cancer, is highly dependent on telomerase to grow, . Moreover, when the subjects were categorized based on the median value of telomerase activity, subjects with low telomerase activity were at a significantly increased risk of lung cancer compared to subjects with high telomerase activity (adjusted odds ratio = 3.05, 95% confidence interval = 1.60-5.82, P = 7 10(-4)). Rapid inhibition of cancer cell growth induced by lentiviral delivery and expression of mutant-template telomerase RNA and anti-telomerase short-interfering RNA.
