Somatic retinoblastoma 1 () loss is prevalent across different cancer types and is enriched in treatment-refractory tumors, such as castration-resistant prostate cancer (CRPC) and small-cell lung cancer, but cannot be considered as a direct druggable target. In this study, we revealed that the close proximity of nudix hydrolase 15 () and may result in their common somatic codeletion or epigenomic cosilencing in different cancer types and subsequent significant positive correlations of their expressions at the bulk transcriptional and single-cell levels. With clinical CRPC samples, co-loss of and were commonly observed (14 out of 21).

Background: Non-small cell lung cancer (NSCLC) remains one of the most prevalent malignancies. A series of differentially expressed genes (DEGs) have been identified in tumor samples and play critical roles in modulating the characteristics of tumor cells. However, some DEGs are specifically expressed in the tumor microenvironment (TME) cells.

Low-dimensional magnetic materials have garnered significant interest due to their unique physical properties and potential applications. Nevertheless, the synthesis of one-dimensional (1D) magnetic materials presents challenges, and the properties of these 1D materials at the single-chain limit have not been well investigated. We here explore experimentally and theoretically 1D CrX (X= Cl, Br, I) magnetic single chains residing within carbon nanotubes.

Nonhuman primates, particularly rhesus macaques, have served as crucial animal models for investigating complex brain functions. While previous studies have explored neural activity features in macaques, the gyro-sulcal functional dissociation characteristics are largely unknown. In this study, we employ a deep learning model named one-dimensional convolutional neural network to differentiate resting state functional magnetic resonance imaging signals between gyri and sulci in macaque brains, and further investigate the frequency-specific dissociations between gyri and sulci inferred from the power spectral density of resting state functional magnetic resonance imaging.

Background: In laparoscopic gastrectomy, liver retraction is an important procedure to obtain a sufficient operative view to ensure the quality of surgery. However, postoperative liver dysfunction is frequently encountered after liver retraction. This study aims to explore the effect of a modified liver retraction method (MLR) we designed on the postoperative liver function of patients receiving laparoscopic radical gastrectomy.

The gut microbiota crucially regulates the efficacy of immune checkpoint inhibitor (ICI) based immunotherapy, but the underlying mechanisms remain unclear at the single-cell resolution. Using single-cell RNA sequencing and subsequent validations, we investigate gut microbiota-ICI synergy by profiling the tumor microenvironment (TME) and elucidating critical cellular interactions in mouse models. Our findings reveal that intact gut microbiota combined with ICIs may synergistically increase the proportions of CD8, CD4, and γδ T cells, reduce glycolysis metabolism, and reverse exhausted CD8 T cells into memory/effector CD8 T cells, enhancing antitumor response.

Genomic prediction is a powerful approach that predicts phenotypic traits from genotypic information, enabling the acceleration of trait improvement in plant breeding. Traditional genomic prediction methods have primarily relied on linear mixed models, such as Genomic Best Linear Unbiased Prediction (GBLUP), and conventional machine learning methods like Support Vector Regression (SVR). Traditional methods are limited in handling high-dimensional data and nonlinear relationships.

Therapeutic tumor vaccines, which activate self-T cells to eliminate tumors, hold tremendous promise in future cancer immunotherapy with high specificity and low side effects. To effectively activate T cell, dendritic cells (DCs) need simultaneously provide three indispensable signals to naive T cells, including MHC-antigen signal, costimulation signal and cytokine stimulation. However, current marketed therapeutic tumor vaccines still suffer from lacking the ability to activate three stimulation signals at the same time, which resulted to the low response rate and unsatisfied therapeutic efficiency.

GOx-mediated glucose depletion offers an alternative noninvasive strategy for tumor therapy, but its lower catalytic activity limits its clinical application. Herein, we designed a temperature-sensitive nano-GOx (NG) that was constructed by gold nanorods chemically modified with GOx (AuNRs-GOx) and coated with temperature-sensitive lipids. The chemical linkage could maintain the natural conformation of GOx, ensuring that NG exerted powerful catalytic activity within the tumor and initiated antitumor immune response through moderate starvation and mild photothermal therapy (mPTT) to coregulating dendritic cells (DCs) and tumor-associated macrophages (TAMs).

Mutations in isocitrate dehydrogenase (IDH) 1 or 2 are identified in various cancers. Accumulated ()-2-hydroxyglutarate (2-HG) caused by mutant IDHs leads to blockage of cell differentiation, thereby inducing malignant transformation. Herein we describe the medicinal chemistry efforts that discovered novel mutant IDH inhibitor HMPL-306 (ranosidenib) via structure-activity relationship studies and pharmacokinetic optimization from internal hit compound .

Ordering has been extensively studied in many visualization applications, such as axis and matrix reordering, for the simple reason that the order will greatly impact the perceived pattern of data. Many quality metrics concerning data pattern, perception, and aesthetics are proposed, and respective optimization algorithms are developed. However, the optimization problems related to ordering are often difficult to solve (e.

Maturity date considerably influences fruit marketing period and commercial value and it is of particular importance in apple due to its association with fruit firmness that determines storage and shelf life, but the underlying mechanism remains unclear. In this study, we report a 61-bp fragment duplication in the MdNAC18.1 promoter that underpins maturity date variation in apple.

Tumor cells transmit various immunosuppressive signals and induce a dysfunctional state in T cells, which essentially leads to immune escape and tumor progression. However, developing effective strategies to counteract the domestication of T cells by tumor cells remains a challenge. Here, we prepared pH-responsive lipid nanoparticles (NL/PLDs) co-loaded with PCSK9 shRNA, lonidamine (LND), and low-dose doxorubicin (DOX).

Article Synopsis
  • A new machine learning method, called SU-VAE, allows scientists to separate brain connectome data shared between humans and macaques from species-specific traits.
  • This method was validated by linking unique human features to cognitive abilities, while shared features aligned more with sensorimotor skills.
  • The results suggest that human-specific brain traits may make networks more efficient and are associated with certain genes related to axon guidance.

Bud endodormancy in deciduous fruit trees is an adaptive trait evolved by selection for the capacity to survive unfavorable environmental conditions. Deciduous trees require a certain amount of winter chill named chilling requirement (CR) to promote bud endodormancy release. In recent decades, global warming has endangered the chill accumulation in deciduous fruit trees.

Peach (), a significant economic fruit tree in the Rosaceae family, is extensively cultivated in temperate and subtropical regions due to its abundant genetic diversity, robust adaptability, and high nutritional value. Originating from China over 4000 years ago, peaches were introduced to Persia through the Silk Road during the Han Dynasty and gradually spread to India, Greece, Rome, Egypt, Europe, and America. Currently grown in more than 80 countries worldwide, the expansion of peach cultivation in Egypt is mainly due to the development and utilization of peach varieties with low chilling requirements.
