Immunological biomarkers of response and resistance to treatment with cabozantinib and nivolumab in recurrent endometrial cancer
Journal for Immunotherapy of Cancer. 2025 Feb 25. PMID: 40010771
This work, focused on defining biomarkers of novel immunotherapy treatment, is the first in-depth correlative analysis of an antiangiogenic + checkpoint drug combination in recurrent endometrial cancer. Authors found blood plasma proteins predicting clinical response to combination treatment, with macrophage-related and T cell activation markers associated respectively with poor and improved survival. The implications of the mechanisms unveiled through this study point to developing future treatments that may counteract the negative signals observed while boosting the immunogenicity of the tumor to further improve responses. If confirmed in future studies, the biomarkers defined here would be a potential way to screen for patients more likely to respond to immunotherapy treatment vs. those who may not benefit.

John Mascarenhas, MD; Hannah Levavi, MD, and team welcomed Mark Geyer, MD, from Memorial Sloan Kettering Cancer Center for the first annual Adult Leukemia Program Visiting Professorship at Mount Sinai. Dr. Geyer spent a week in February with the multidisciplinary adult leukemia team—faculty from the leukemia, myeloproliferative neoplasms, and bone marrow transplant teams; Hematology/Oncology fellows; nurses, advanced practice providers and social workers—giving grand rounds and journal club presentations, discussing complex cases and emerging treatments, and addressing common practical challenges in managing acute lymphoblastic leukemia.

Oncofetal reprogramming drives phenotypic plasticity in WNT-dependent colorectal cancer
Nature Genetics. 2025 Feb 10. PMID: 39930084
This study reveals that colorectal cancer (CRC) cells can revert to a fetal-like state, helping them survive and proliferate despite treatment. The phenomenon, called oncofetal reprogramming, enables some tumor cells to diversify their molecular characteristics and behavior, rendering them resistant to current chemotherapies. Findings propose oncofetal reprogramming as a crucial driver of drug-tolerant states in CRC and indicate that success of the current standard of care treatment hinges on effectively targeting this program.

Human-correlated genetic models identify precision therapy for liver cancer
Nature. 2025 Feb 19. PMID: 39972137
In this study, a set of 25 genetically driven immunocompetent in vivo and matched in vitro hepatocellular carcinoma (HCC) models were developed, recapitulating the 4 human subclasses of HCC, and the therapeutic response to therapies was assessed. Dr. Llovet, Director of the Mount Sinai Liver Cancer Program, and team validated the molecular profiles of these preclinical models against human HCC data—they compared the molecular features from 171 patient-derived HCC samples with the 25 experimental HCC models, correlating them into the four subclasses, and demonstrating the clinical relevance of the models developed in the study. The linkage and alignment of the models with patient data will aid in stratifying patients to treatment and identifying novel therapies.

ATRX mutations mediate an immunogenic phenotype and macrophage infiltration in neuroblastoma
Cancer Letters. 2025 Jan 30. PMID: 39892705
This study shows that gene expression and cell-state changes resulting from alterations of ATRX—one of the most frequently mutated genes in high-risk neuroblastoma—associate with a characteristic immune cell infiltration in both in vivo models and patient samples. Findings add to the increasing evidence that ATRX mutant neuroblastoma represents a biologically distinct subgroup of patients and provide insight into the mechanisms underlying the distinct clinical phenotype seen in these patients.

Transcriptional regulatory network analysis identifies GRN as a key regulator bridging chemotherapy and immunotherapy response in small cell lung cancer
Journal of Hematology & Oncology. 2025 Feb 5. PMID: 39910394
In this study, Dr. Watanabe and colleagues performed a comprehensive regulatory network analysis and identified granulin precursor (GRN) as a critical regulator associated with resistance to both chemotherapy and immunotherapy in patients with small cell lung cancer (SCLC). Results highlight GRN as a critical regulator of chemo-resistance and a potential biomarker for immunotherapy resistance in SCLC. Targeted therapeutic strategies for GRN-low patients could improve outcomes, while new approaches are needed for GRN-high patients. Overall, the findings implicate GRN as a bridge between chemotherapy and immunotherapy resistance through GRN-mediated mechanisms.

Metabolic adaptations to acute glucose uptake inhibition converge upon mitochondrial respiration for leukemia cell survival
Cell Communications and Signaling. 2025 Jan 25. PMID: 39863913
This study investigated a potent small molecule inhibitor to Class I glucose transporters, KL-11743, using glycolytic leukemia cell lines and patient-based model systems to provide mechanistic insights into metabolic adaptations. Using a combination of targeted and unbiased metabolomics, real-time bioenergetics analyses, and high-content live-cell imaging in the context of multiple leukemic models, Dr. Chipuk and team dissected the cellular responses to acute glucose uptake inhibition, all of which center on enhanced mitochondrial function. Findings provide insights into the metabolic adaptations and dependencies that arise in leukemic cells under glucose-deprived conditions, presenting potential therapeutic opportunities for clinical interventions.

A PROTAC degrader suppresses oncogenic functions of PTK6, inducing apoptosis of breast cancer cells
Cell Chemical Biology. 2025 Feb 25. PMID: 39541980
Dr. Irie and colleagues report that MS105, a PTK6 PROTAC degrader, induces apoptosis of breast cancer cells by targeting kinase-dependent and independent functions of PTK6. Findings support PTK6 degraders as a preferred approach to targeting PTK6, an oncogene in breast and other cancer types (prostate, gynecological, liver). Ongoing studies are evaluating the in vivo efficacy of MS105.

Sympathetic nerve signaling rewires the tumor microenvironment: a shift in "microenvironmental-ity”
Cancer Metastasis Reviews. 2025 Jan 20. PMID: 39831934
Dr. Kyprianou and colleagues review the current evidence on the multidirectional impacts of sympathetic nerves and both immune and non-immune tumor microenvironment (TME) components, the nature of these communication processes, and how exploring these interactions may inform future therapeutics to impair cancer progression and metastasis. The studies reviewed emphasize the need to map the spatial profiles of multidirectional interactions within the TME, including the distance-dependent effects of sympathetic signaling. Such quantitative insights will be pivotal in developing computational models to predict the molecular and phenotypic changes resulting from combinatorial treatments.
