Predicting Survival Rates in Brain Metastases Patients from Non-Small Cell Lung Cancer Using Radiomic Signatures Associated with Tumor Immune Heterogeneity.

Non-small cell lung cancer (NSCLC) frequently metastasizes to the brain, significantly worsened prognoses. This study aimed to develop an interpretable model for predicting survival in NSCLC patients with brain metastases (BM) integrating radiomic features and RNA sequencing data. 292 samples are collected and analyzed utilizing T1/T2 MRIs.

ETV7 limits the antiviral and antitumor efficacy of CD8 T cells by diverting their fate toward exhaustion.

Terminal exhaustion is a critical barrier to antitumor immunity. By integrating and analyzing single-cell RNA-sequencing and single-cell assay for transposase-accessible chromatin with sequencing data, we found that ETS variant 7 (ETV7) is indispensable for determining CD8 T cell fate in tumors. ETV7 introduction drives T cell differentiation from memory to terminal exhaustion, limiting antiviral and antitumor efficacy in male mice.

Multi-TACs: Targeting Solid Tumors with Multiple Immune Cell Co-engagers.

Multiple immune components in the complex and heterogeneous tumor-immune microenvironment (TIME) work cooperatively to promote or impede cancer immunotherapy. Synergistically co-managing multiple immune cells with single agents for advanced antitumor immunity remains desirable but challenging. This In Focus article introduces a triple orthogonal linker (T-Linker)-based multimodal targeting chimera (Multi-TAC) platform, enabling the single-agent-mediated tumor-targeted co-engagement of multiple immune cell types within TIME for potentiated immunotherapy.

The epitranscriptional factor PCIF1 orchestrates CD8 T cell ferroptosis and activation to control antitumor immunity.

T cell-based immunotherapies have revolutionized cancer treatment, yet durable responses remain elusive. Here we show that PCIF1, an RNA N 2'-O-dimethyladenosine (mA) methyltransferase, negatively regulates CD8 T cell antitumor responses. Whole-body or T cell-specific Pcif1 knockout (KO) reduced tumor growth in mice.

Adaptive fusion of dual-view for grading prostate cancer.

Accurate preoperative grading of prostate cancer is crucial for assisted diagnosis. Multi-parametric magnetic resonance imaging (MRI) is a commonly used non-invasive approach, however, the interpretation of MRI images is still subject to significant subjectivity due to variations in physicians' expertise and experience. To achieve accurate, non-invasive, and efficient grading of prostate cancer, this paper proposes a deep learning method that adaptively fuses dual-view MRI images.

Arginine methylation-dependent TRIM47 stability mediated by CARM1 promotes the metastasis of hepatocellular carcinoma.

The tripartite motif (TRIM) protein family has been shown to play important roles in the occurrence and development of various tumors. However, the biological functions of TRIM47 and its regulatory mechanism in hepatocellular carcinoma (HCC) remain unexplored. Here, we showed that TRIM47 was upregulated in HCC tissues compared with adjacent normal tissues, especially at advanced stages, and associated with poor prognosis in HCC patients.

Multimodal targeting chimeras enable integrated immunotherapy leveraging tumor-immune microenvironment.

Although immunotherapy has revolutionized cancer treatment, its efficacy is affected by multiple factors, particularly those derived from the complexity and heterogeneity of the tumor-immune microenvironment (TIME). Strategies that simultaneously and synergistically engage multiple immune cells in TIME remain highly desirable but challenging. Herein, we report a multimodal and programmable platform that enables the integration of multiple therapeutic modules into single agents for tumor-targeted co-engagement of multiple immune cells within TIME.

SCG2 Mediates HNSCC Progression With CCL2/TGFβ1 M2 Macrophage Infiltration.

Automated electrosynthesis reaction mining with multimodal large language models (MLLMs).

Leveraging the chemical data available in legacy formats such as publications and patents is a significant challenge for the community. Automated reaction mining offers a promising solution to unleash this knowledge into a learnable digital form and therefore help expedite materials and reaction discovery. However, existing reaction mining toolkits are limited to single input modalities (text or images) and cannot effectively integrate heterogeneous data that is scattered across text, tables, and figures.

Repulsive guidance molecules b (RGMb): molecular mechanism, function and role in diseases.

Repulsive guidance molecule b (RGMb), a glycosylphosphatidylinositol-anchored member of the RGM family, is initially identified as a co-receptor of bone morphogenetic protein (BMP) in the nervous system. The expression of RGMb is transcriptionally regulated by dorsal root ganglion 11 (DRG11), which is a transcription factor expressed in embryonic DRG and dorsal horn neurons and plays an important role in the development of sensory circuits. RGMb is involved in important physiological processes such as embryonic development, immune response, intercellular adhesion and tumorigenesis.

Analysis of Indicators for Assessing the Risk of Progression from PACS to APAC and the Degree of Intraocular Pressure Elevation in APAC Using AS-OCT.

Objective: The aim of this study is to quantify anterior chamber parameters to provide potential risk indicators for evaluating the progression of primary angle-closure suspect (PACS) eyes to acute primary angle closure (APAC) and the degree of intraocular pressure elevation in patients with APAC utilizing anterior segment optical coherence tomography (AS-OCT).

Methods: Tomey CASIA2 AS-OCT was used to quantitatively measure various anterior chamber parameters, including anterior chamber depth (ACD), anterior chamber volume (ACV), lens thickness (LT), lens vault (LV), iris-trabecular contact index (ITC), iris thickness (IT), iris volume (IV), iris curvature (IC), iris area (IA), and iris thickness (IT), in APAC eyes (30 eyes) and contralateral PACS eyes (30 eyes) of 30 patients. The differences in these parameters between the two groups and their relationship with intraocular pressure were analyzed.

RAPIDASH: Tag-free enrichment of ribosome-associated proteins reveals composition dynamics in embryonic tissue, cancer cells, and macrophages.

Ribosomes are emerging as direct regulators of gene expression, with ribosome-associated proteins (RAPs) allowing ribosomes to modulate translation. Nevertheless, a lack of technologies to enrich RAPs across sample types has prevented systematic analysis of RAP identities, dynamics, and functions. We have developed a label-free methodology called RAPIDASH to enrich ribosomes and RAPs from any sample.

Enhancing humidity resistance of nickel-rich layered cathode materials by low water-soluble CaF coating.

A low water-solubility but hydrophilic coating of CaF is demonstrated to be effective in mitigating the susceptibility of nickel-rich cathodes to moisture and even water. The ability of the cathode to resist water erosion is not inherently linked to either hydrophobicity or hydrophilicity, but lies in robust chemical bonding within the protective layer exhibiting low water solubility.
