Telomir Pharmaceuticals Reports New Data Showing Telomir-1 Resets Cancer's “Kill-and-Clean” Defense Systems in an Aggressive Prostate Cancer Model, Outperforming Rapamycin and Chemo

About this update from Telomir Pharmaceuticals, Inc.

New findings highlight Telomir-1's impact on CASP8 and GSTP1, two critical genes that regulate cell death and glutathione-based detoxification pathways often disrupted in cancer. MIAMI, FLORIDA / ACCESS Newswire / October 23, 2025 / Telomir Pharmaceuticals, Inc. (NASDAQ:TELO) ("Telomir" or the "Company"), a pre-clinical biotechnology company developing therapies that target the epigenetic roots of cancer, aging, and age-related disease, today reported new preclinical data from an in vivo study in mice bearing human aggressive prostate cancer tumors evaluating DNA-methylation changes in two key defense genes - CASP8 and GSTP1 - following treatment with oral Telomir-1 , Rapamycin, chemotherapy, and combination regimens. Apoptosis ("kill") and detoxification ("clean") pathways are two of the body's fundamental defense systems against cancer initiation and progression, and Telomir-1's observed modulation of these pathways through DNA-methylation control may represent an important area of ongoing scientific evaluation in oncology research. Overview of Findings The study examined DNA methylation , a central epigenetic process that helps determine whether genes are active or silenced. In this model, baseline tumor samples exhibited DNA hypermethylation of CASP8 and GSTP1, a pattern often associated with reduced activity in genes involved in apoptosis and detoxification. Why These Pathways Matter in Cancer Biology Apoptosis and detoxification represent two of the body's most fundamental defense systems against cancer initiation and progression. By addressing both apoptotic and detoxification imbalances through DNA methylation modulation, Telomir-1 may engage two complementary mechanisms commonly disrupted in cancer biology. Rapamycin Comparison At earlier observation points (Day 10), Rapamycin - an mTOR-pathway inhibitor - was associated with an initial reduction in DNA methylation for both genes. This observation aligns with Rapamycin's indirect influence on cellular metabolism and oxidative stress , which can temporarily affect DNA methylating enzyme activity. By Day 21, methylation levels partially rebounded, suggesting that the effect may have been transient and metabolically driven rather than a direct epigenetic reset. Telomir-1 , by contrast, was associated with a progressive and more sustained decrease in methylation through Day 21. Unlike Rapamycin, Telomir-1 is believed to interact with epigenetic regulatory enzymes that add or remove methyl groups from DNA and histones, which may contribute to the durability of its observed effects in this preclinical model. Interpretation Collectively, these preclinical observations indicate that Telomir-1 influenced two complementary cellular pathways - apoptosis and detoxification - through DNA methylation modulation not observed with chemotherapy and more sustained than that seen with Rapamycin. The data suggest Telomir-1 may act at the level of epigenetic enzyme regulation , whereas Rapamycin's effects appear secondary to metabolic signaling. Further studies are planned to clarify these mechanisms and their potential relevance for oncology research. Scientific Perspective "This preclinical work, which supports earlier studies with Telomir-1 on DNA methylation in cancer, helps differentiate the epigenetic modulation observed with Telomir-1 from the indirect metabolic effects of Rapamycin," said Dr. Itzchak Angel, CSA at Telomir. "By evaluating DNA methylation dynamics in apoptosis and detoxification pathways, we are building a scientific framework for understanding how Telomir-1 may help restore epigenetic balance in cancer models. " CEO Perspective "Our goal is to develop medicines that don't just treat what cancer becomes but help reset the biology that lets it begin. Telomir-1 may represent that next frontier.
