Takeaways from meta-analysis: indications of combinational treatments for glioblastoma.

Background: Patients with brain cancers are diagnosed based on MRI in the clinical setting while molecular signatures offer potential therapeutic targets. The necessity to re-form molecular and imaging information motivated our meta-analysis to decipher the correlation between the MRI-classified tumor locations, gene expression, and protein signatures in GBM.

Methods: We analyzed spatial and omics data alongside the assessment of post-translational modifications.

Bridging Gaps in Antibody Responses and Animal Welfare: Assessing Blood Collection Methods and Vaginal Immunity in Mice Immunized with Intranasal Gonococcal Vaccines.

Assessing antibody titers and functional responses is essential for evaluating vaccine efficacy, yet the impact of blood collection methods on these immunological assessments remains unclear. Retro-orbital (RO) blood collection is commonly used but significant complications can occur. Increasingly, investigators have adopted alternative blood collection approaches, such as saphenous vein (SV) sampling to improve laboratory animal welfare.

A lightweight network for traffic sign detection via multiple scale context awareness and semantic information guidance.

Traffic sign detection, as a critical branch of object detection, plays an essential role in both assisted driving and autonomous driving technologies. In this paper, we propose MASG-Net, a lightweight detection network designed to improve the accuracy and efficiency of traffic sign detection. First, we introduce a channel attention mechanism into MobileNetV3 to create a novel E-block structure and design E-mobilenet, a lightweight backbone network, to replace the backbone in YOLOv4-tiny, significantly enhancing feature extraction while reducing parameters.

CaMYBA-CaMYC-CaTTG1 complex activates the transcription of anthocyanin synthesis structural genes and regulates anthocyanin accumulation in pepper ( L.) leaves.

Anthocyanins are flavonoid-derived metabolites that contribute to plant and human health. At present, few studies have studied the biosynthesis and accumulation mechanism of anthocyanins in pepper leaves. The role of CaMYBA-CaMYC-CaTTG1 complex in anthocyanin biosynthesis in pepper leaves was studied.

Monochromatic Responsive HOF Heterostructures via VIA-Group-Based Framework Hybridization for Fully-Covert Photonic Barcode.

Luminescent responsive heterostructures with region-domained emission and integrated responsiveness exhibit great potential in information security, but always suffer from the direct exposure of fingerprint information at the initial state, making it easy to decode the hidden confidential information. Herein, the first monochromatic responsive hydrogen-bonded organic framework (HOF) heterostructures are reported based on VIA-group-based framework hybridization toward fully-covert photonic barcodes. Designed HOF blocks with different VIA-group elements are integrated via a configuration-assimilation-based assembly method to generate the intrinsic monochromatic HOF heterostructures.

Muskelin is a substrate adaptor of the highly regulated Drosophila embryonic CTLH E3 ligase.

The maternal-to-zygotic transition (MZT) is a conserved developmental process where the maternally-derived protein and mRNA cache is replaced with newly made zygotic gene products. We have previously shown that in Drosophila the deposited RNA-binding proteins ME31B, Cup, and Trailer Hitch are ubiquitylated by the CTLH E3 ligase and cleared. However, the organization and regulation of the CTLH complex remain poorly understood in flies because Drosophila lacks an identifiable substrate adaptor, and the mechanisms restricting the degradation of ME31B and its cofactors to the MZT are unknown.

Proteogenomic characterization of highly enriched viable leukemic blasts in acute myeloid leukemia: A SWOG report.

Introduction: Acute myeloid leukemia (AML) remains one of the deadliest hematopoietic malignancies. A better understanding of the molecular biology governing AML may lead to improved risk stratification and facilitate the development of novel therapies. Proteins are responsible for much of the biology of cells.

Overexpression of HIF2α Enhances the Angiogenesis-Promoting Effect of hUC-MSC-Derived Extracellular Vesicles by Stimulating miR-146a.

Objective: This study aimed to explore whether excessive HIF2α can amplify the impact of human Umbilical Cord Mesenchymal Stem Cell-derived Extracellular Vesicles (hUC-MSC- EVs) on endothelial cells.

Methods: In this study, we created HIF2α-overexpressing hUC-MSC-EVs and compared their pro-angiogenic effects with control EVs on Human Umbilical Vein Endothelial Cells (HUVECs). MTT assay and Edu staining were used to detect the viability and proliferation ability of HUVECs, and Transwell and Tube Formation Assays were used to detect cell migration and tube formation ability.

Differentiated Intra-Ligand Charge Transfer Boosting Multicolor Responsive MOF Heterostructures as Robust Anti-Counterfeiting Labels.

Metal-organic framework (MOF) heterostructures with hybrid architectures and abundant functional sites possess great potential applications in advanced information security, yet still suffer from the harsh stimuli mechanisms with restrained emission control. Herein, the differentiated design strategy on intra-ligand charge transfer is first reported to realize smart-responsive multicolor MOF heterostructures as robust anticounterfeiting labels. Designed similar MOF blocks with the differentiated intra-ligand charge transfer are integrated via time-dependent epitaxial growth to form multicolor MOF heterostructures.

Muskelin acts as a substrate receptor of the highly regulated CTLH E3 ligase during the maternal-to-zygotic transition.

The maternal-to-zygotic transition (MZT) is a conserved developmental process where the maternally-derived protein and mRNA cache is replaced with newly made zygotic gene products. We have previously shown that in the deposited RNA-binding proteins ME31B, Cup, and Trailer Hitch (TRAL) are ubiquitylated by the CTLH E3 ligase and cleared. However, the organization and regulation of the CTLH complex remain poorly understood in flies.

Characterization of an expanded set of assays for immunomodulatory proteins using targeted mass spectrometry.

Immunotherapies are revolutionizing cancer care, but many patients do not achieve durable responses and immune-related adverse events are difficult to predict. Quantifying the hundreds of proteins involved in cancer immunity has the potential to provide biomarkers to monitor and predict tumor response. We previously developed robust, multiplexed quantitative assays for immunomodulatory proteins using targeted mass spectrometry, providing measurements that can be performed reproducibly and harmonized across laboratories.

Bilateral keratitis associated with afatinib therapy.

This case discussed a significant ocular side effect, bilateral keratitis, which could be induced by afatinib, an irreversible epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI). We explored the disease progression of a 52-year-old, stage IV nasopharyngeal carcinoma male patient, who was under afatinib treatment and had experienced progressive bilateral eye dryness and tenderness on increasing afatinib from 40 mg every other day to 40 mg daily. Clinical examination noted bilateral visual acuity reduction, diffuse superficial punctate keratopathy in the right eye, and a central epithelial defect in the left eye.

RNA and phosphoprotein profiles of TP53- and PTEN-knockouts in MCF10A at baseline and responding to DNA damage.

A wealth of proteogenomic data has been generated using cancer samples to deepen our understanding of the mechanisms of cancer and how biological networks are altered in association with somatic mutation of tumor suppressor genes, such as TP53 and PTEN. To generate functional signatures of TP53 or PTEN loss, we profiled the RNA and phosphoproteomes of the MCF10A epithelial cell line, along with its congenic TP53- or PTEN-knockout derivatives, upon perturbation with the monofunctional DNA alkylating agent methyl methanesulfonate (MMS) vs. mock treatment.

A multiplexed assay for quantifying immunomodulatory proteins supports correlative studies in immunotherapy clinical trials.

Introduction: Immunotherapy is an effective treatment for a subset of cancer patients, and expanding the benefits of immunotherapy to all cancer patients will require predictive biomarkers of response and immune-related adverse events (irAEs). To support correlative studies in immunotherapy clinical trials, we are developing highly validated assays for quantifying immunomodulatory proteins in human biospecimens.

Methods: Here, we developed a panel of novel monoclonal antibodies and incorporated them into a novel, multiplexed, immuno-multiple reaction monitoring mass spectrometry (MRM-MS)-based proteomic assay targeting 49 proteotypic peptides representing 43 immunomodulatory proteins.

Internal Standard Triggered-Parallel Reaction Monitoring Mass Spectrometry Enables Multiplexed Quantification of Candidate Biomarkers in Plasma.

Despite advances in proteomic technologies, clinical translation of plasma biomarkers remains low, partly due to a major bottleneck between the discovery of candidate biomarkers and costly clinical validation studies. Due to a dearth of multiplexable assays, generally only a few candidate biomarkers are tested, and the validation success rate is accordingly low. Previously, mass spectrometry-based approaches have been used to fill this gap but feature poor quantitative performance and were generally limited to hundreds of proteins.
