Putting the STING back into BH3-mimetic drugs for TP53-mutant blood cancers

Cancer Cell

The study looked at how a protein called TP53 helps fight blood cancers. The study found that a type of drug called BH3-mimetic drugs work better when TP53 is present. The study also found that TP53 is activated in a special way when these drugs are used, which helps the drugs work even better. The study used a special type of drug called a STING agonist to help activate TP53 in this way. The study found that using these drugs together killed blood cancer cells very effectively. The study suggests that this combination of drugs could be used to treat TP53-mutant blood cancers in the clinic.

Glioblastoma evolution and heterogeneity from a 3D whole-tumor perspective

Cell

The study aims to investigate the intratumoral heterogeneity and evolution of glioblastoma using 3D neuronavigation during surgical resection to acquire samples representing the whole tumor mapped by 3D spatial coordinates. The study tests the hypothesis that GBM evolutionary trajectories can be inferred from neurodevelopmental lineage origins and initiating events such as chromothripsis to emergence of genetic subclones and spatially restricted activation of differential tumor and microenvironmental programs in the core, periphery, and contrast-enhancing regions.

Theranostic Bottle-Brush Polymers Tailored for Universal Solid-Tumor Targeting

ACS Nano

The study compares the outcomes observed under different experimental conditions or interventions, specifically focusing on the optimized polymer bearing (oligo(ethylene glycol) methyl ether methacrylate) in the side chains. The results show reduced macrophage uptake, prolonged blood-circulation time (up to 27 h), and exceptionally high accumulation in the tumor compared to the liver, elucidating an immune-evasion-induced tumor-targeting mechanism. The outstanding tumor-targeting ability has been further validated across five distinct tumor models, including orthotopic glioblastoma and pancreatic cancer, demonstrating the universality of the polymeric nanocarrier for tumor-targeting delivery.

Temporal dynamics of the multi-omic response to endurance exercise training

Nature

The MoTrPAC study suggests that endurance training can enhance immune system function, potentially improving the efficacy of immunotherapies used in cancer treatment. It also highlights how exercise-induced changes in metabolic pathways may influence cancer progression and management, particularly in regulating cancer cachexia and inhibiting cancer cell growth. Additionally, the study reveals that exercise upregulates heat shock proteins, which could inform novel approaches to reduce tumor resistance in cancer therapy.

Why is exercise good for you? Scientists are finding answers in our cells

Nature

The paper explores the molecular basis of how exercise impacts health, emphasizing its potential implications for cancer research and treatment. It details how physical activity induces a variety of cellular and molecular responses that can enhance immune function, reduce inflammation, and improve cellular repair, all of which are crucial for cancer prevention and management. Specifically, exercise triggers the release of cytokines like interleukin-6 (IL-6), which, during physical activity, promotes anti-inflammatory effects that could be therapeutic in cancer contexts. Moreover, the study highlights the potential for developing exercise-mimicking drugs that might replicate some of these protective effects in cancer patients who are unable to exercise.

Do cutting-edge CAR-T-cell therapies cause cancer? What the data say

Nature

The FDA has initiated an investigation into CAR-T cell therapies after detecting cases of lymphoma in patients treated with this cancer therapy. Concerns arise from the genetic engineering process used in CAR-T therapy, which involves altering a patient's T cells to target cancer cells but may inadvertently increase cancer risk through insertional mutagenesis. The investigation highlights the need to balance the transformative potential of CAR-T against the risks of secondary malignancies.

Sequential CD7 CAR T-Cell Therapy and Allogeneic HSCT without GVHD Prophylaxis

The New England Journal of Medicine

This study tested a new way to treat patients with a type of cancer called relapsed or refractory hematologic cancers. The treatment involved using a special type of cell called CAR T-cells to fight the cancer, followed by a procedure called haploidentical HSCT. The study found that this approach was safe and effective, with most patients achieving complete remission and some experiencing serious but reversible side effects. The estimated 1-year overall survival was 68% and the estimated 1-year disease-free survival was 54%.

TRBC1-targeting antibody-drug conjugates for the treatment of T cell cancers

Nature

The study compares the outcomes observed under different experimental conditions or interventions, including preclinical studies and the first-in-human clinical trial of anti-TRBC1 CAR T cells. The results show that CAR T cells are lost due to killing by the patient's normal T cells, reducing their efficacy. The study identifies this issue as a significant limitation of the first-in-human clinical trial. The key findings of the study suggest that an antibody-drug conjugate may provide an optimal format for TRBC1 targeting and produce superior responses in patients with T cell cancers.

Atorvastatin for Anthracycline-Associated Cardiac Dysfunction The STOP-CA Randomized Clinical Trial

JAMA

The STOP-CA trial examined the effectiveness of atorvastatin in preventing cardiac dysfunction in patients with lymphoma treated with anthracyclines. Results showed that atorvastatin significantly reduced the risk of a substantial decline in left ventricular ejection fraction (LVEF) compared to placebo over 12 months. This suggests that atorvastatin may be beneficial in managing anthracycline-induced cardiac dysfunction, supporting its use in high-risk cancer patients receiving this type of chemotherapy.

Somalier: rapid relatedness estimation for cancer and germline studies using efficient genome sketches

Genome Medicine

Somalier is a tool that helps researchers figure out if samples from a patient have been mixed up during sequencing. It does this by looking at the genetic information from the samples and comparing them to each other. The study shows that Somalier can accurately measure relatedness in large groups of samples and distinguish pairs of whole-genome and RNA-seq samples from the same individuals. This is important because it can help researchers better understand the genetic changes that occur in tumors and how they relate to the patient's overall health.

CICERO: a versatile method for detecting complex and diverse driver fusions using cancer RNA sequencing data

Genome Biology

The study demonstrates the potential of CICERO to detect driver fusions beyond the canonical exon-to-exon chimeric transcripts. The study identifies previously unreported kinase fusions and a high prevalence of EGFR C-terminal truncation in TCGA glioblastoma RNA-seq, which could have important clinical implications. The study suggests future research directions, such as integrating CICERO with other genomic and clinical data to improve driver fusion detection and develop personalized treatment strategies for cancer patients.

Magnetic Field-Optimized Paramagnetic Nanoprobe for/Switchable Histopathological-Level MRI

ACS Nano

The study creates special nanoparticles that can be used to see inside the body using a MRI machine. These nanoparticles are designed to be sensitive to a chemical called glutathione, which is found in the body. When the nanoparticles are exposed to glutathione, they change color, which can be seen on the MRI machine. The study finds that these nanoparticles work better than traditional nanoparticles because they are more sensitive to glutathione and can show more details of the body on the MRI machine. The study also suggests ways to make these nanoparticles even better in the future.

AI-enabled electrocardiography alert intervention and all-cause mortality: a pragmatic randomized clinical trial

The study demonstrated that an AI-enabled electrocardiogram (ECG) can significantly improve patient outcomes by identifying hospitalized patients at high risk of mortality. Implementation of the AI-ECG alert, which notifies physicians about high-risk patients, was associated with a significant reduction in all-cause and cardiac-specific mortality within 90 days. This approach facilitated more timely and intensive care for patients with high-risk ECGs, underscoring the potential of AI tools in enhancing predictive accuracy and improving clinical interventions in cancer treatment.
