Your epigenome may record the exposures of your life. At our Aging & Cancer Lab seminar, Silvana Maas (Seoane Lab) showed how lifestyle and environmental exposures leave marks on DNA that can be decoded to reconstruct exposures linked to early-onset colorectal cancer. #Aging&CancerLabseminars

Eric J. Chow et al. find that dexrazoxane given with doxorubicin in childhood cancer is linked to improved long-term cardiac function and lower risk of poor left ventricular function in adult survivors. #JournalClub ascopubs.org/doi/10.1200/...

Piotr et al. report that intravenous iron in a mouse cancer model increases tumor iron, promotes tumor growth, and blunts anti-tumor CD8⁺ T cell responses, reducing immunotherapy/chemo efficacy. #JournalClub www.frontiersin.org/journals/onc...

A shared DNA methylation drift occurs with aging and tumorgenesis in the colon. Age-related inflammation and reduced Wnt signaling, which dysregulate iron metabolism and impair TET activity, drive this epigenetic drift. #JournalClub www.nature.com/articles/s43...

Ferritin buffers intracellular iron and protects cells from iron toxicity. Yi et al. show that deleting the ferritin heavy chain (Fth1) impairs normal HSPC function but restricts AML progression and prolongs survival in mice. #JournalClub www.nature.com/articles/s41...

When Ning, Francesca & Marc were selected to speak @senescel.org 2025, they gave it their all, refining every argument and minute. Their talks put our metabolic bottleneck model of aging on the field’s radar. 👏 What do you think drives tissue aging, the cell or its environment? 🤔

Lung cancer reprograms the bone marrow to its advantage. Hedge et al. ( @miriammerad.bsky.social lab) show that tumors trigger an NRF2-driven stress response in myeloid precursors, which then suppress anti-tumor immunity. Blocking NRF2 boosts immunotherapy. #JC 🔗 www.nature.com/articles/s41...

📰 In aging bone marrow, cancerous clones thrive by adapting through mutations. Kang et al. show that giving immune cells the same mutations tilts the balance back—helping them resist exhaustion and fight cancer in this hostile niche. #JournalClub 🔗 www.science.org/doi/10.1126/...

📰Aging disrupts metabolic supply chains, constraining cell renewal. But how do we detect these shortages? In >5000 patients, Tapio et al. show that low ferritin is the best predictor for bone marrow iron. A study with broad implications. hashtag #JournalClub 🔗 ashpublications.org/bloodadvance...

📑Why don’t senescent cells fix their DNA? Daigh et al. (Meyer lab) report that uncoupling mTORC1 from E2F sustains transcription-linked DNA damage in senescence. #JournalClub www.nature.com/articles/s41...

Why do TET2-mutant preleukemic cells outcompete healthy HSCs? Yang et al. show that these cells upregulate MPL (thrombopoietin receptor, TPO-R) signaling, giving a clonal edge; inhibiting this pathway reduces it. #JournalClub www.nature.com/articles/s41...

Why do ring sideroblasts arise in MDS? Often via SF3B1-driven mitochondrial iron buildup. Inokura et al. tested TET2’s role: Tet2-deficient mice show systemic iron overload, and anemia. No classical RS, but intriguing parallels. #JournalClub www.exphem.org/article/S030...

🌱We are delighted to welcome Gloria Ariño from Universidad Europea de Madrid as our third summer intern!🌟 Gloria will explore how aging creates metabolic bottlenecks in the colon and how these shape tumorigenesis. With Gloria, Laura & Aiste, our summer intern dream team is complete!💪

📑Immunotherapy responses differ markedly between MMR-proficient and -deficient colorectal cancers. A scRNA-seq study of 62 patients by ‪@pelkalab.bsky.social‬ et al. (Hacohen lab) reveals key immune–tumor communication differences that may explain this. #JournalClub www.cell.com/cell/fulltex...

🎯 The Aging and Cancer Lab is not afraid of tough battles — in science or laser tag. What connects aging and cancer? Can we stop it? We team up and take aim together at the route causes.. 🔬💥

🌱Excited to welcome Aistė Avižaitė from Lithuania’s @VU_LT to the lab this summer! She’ll be studying how chemotherapy alters metabolism in healthy tissues and how this may drive accelerated aging in childhood cancer survivors. #Aging #Cancer #SummerIntern

200 years ago in Barcelona, your 40s meant preparing for death. Today, you might have 40 more years ahead. But as @sjayolshansky et al. show, most gains came from reducing early death. Further progress depends on tackling aging and its consequences. #JC www.nature.com/articles/s43...

🌱 Welcome aboard, Laura! Joining us this summer from @URV_universitat, Laura Boró García will be exploring how aging and chemotherapy disrupt metabolism and epigenetics in the bone marrow. We’re thrilled to have her with us! 🧬🧪 #Aging #Cancer #SummerIntern

Longer lives in laboratory conditions may compromise survival in the real world. In a large study on genetically diverse mice, Di Francesco et al. in Jackson Labs show that lifespan extension under caloric restriction doesn’t always improve health. #JournalClub www.nature.com/articles/s41...
