Principal Component-Based Clinical Aging Clocks Identify Signatures of Healthy Aging and Targets for Clinical Intervention

Clinical Aging Clock Based on Principal Components Reveals Characteristics of Healthy Aging and Targets for Clinical Interventions Background of the Study As the population ages, promoting healthy aging and slowing down biological aging has become an important issue. To accurately predict all-cause mortality and obtain feasible measures to promote ...

A mild increase in nutrient signaling to mTORC1 in mice leads to parenchymal damage, myeloid inflammation, and shortened lifespan

Research on the Impact of Nutritional Signals on the Lifespan of Mice Background and Motivation In recent years, the intensification of global aging has posed unprecedented challenges to medicine, socio-economics, and philosophy. By 2050, the global population aged 65 and above is expected to grow from 5% at the beginning of the 20th century to 17%...

Inhibition of S6K Lowers Age-Related Inflammation and Increases Lifespan Through the Endolysosomal System

Inhibition of S6K Reduces Age-Related Inflammation and Extends Lifespan through the Endosomal-Lysosomal System Research Background and Problem Description As organisms age, chronic low-grade inflammation (inflammaging) and declined immune function (immunosenescence) become important pathological foundations of many diseases in the elderly, such as ...

Plasma Proteomic Profiles Predict Future Dementia in Healthy Adults

Plasma Proteomic Profiles Predict Future Dementia in Healthy Adults

Plasma Proteomics Predicts the Future Risk of Dementia in Healthy Adults Background and Significance Predicting dementia has always been a significant challenge in the medical field. With the development of proteomics, biomarkers in the blood offer new opportunities for predicting the onset of dementia. This study focuses on data from the UK Bioban...

Epithelial−Mesenchymal Transition Induced by Tumor Cell-Intrinsic PD-L1 Signaling Predicts a Poor Response to Immune Checkpoint Inhibitors in PD-L1-High Lung Cancer

Tumor Cell-Intrinsic PD-L1 Signaling Induces Epithelial-Mesenchymal Transition (EMT) Predicting Poor Response to Immune Checkpoint Inhibitors in PD-L1 High-Expressing Lung Cancer Research Background and Motivation In cancer immunotherapy, Programmed Death Ligand-1 (PD-L1) inhibits immune responses by binding to Programmed Death-1 (PD-1) receptors o...

Synergistic Antitumor Activity by Dual Blockade of CCR1 and CXCR2 Expressed on Myeloid Cells within the Tumor Microenvironment

Synergistic Antitumor Activity by Dual Blockade of CCR1 and CXCR2 Expressed on Myeloid Cells within the Tumor Microenvironment

Achieving Synergistic Antitumor Activity by Dual Blocking of CCR1 and CXCR2 Expression in Myeloid Cells Background Introduction Colorectal Cancer (CRC) poses a global health crisis, with its incidence and mortality rates rapidly rising in recent years. Over the past 15 years, the mortality rate of CRC has increased by more than 30%, and it is expec...

Hypoxia- and Postirradiation Reoxygenation-Induced HMHA1/ARHGAP45 Expression Contributes to Cancer Cell Invasion in a HIF-Dependent Manner

Contribution of HMHA1/ARHGAP45 Expression Induced by Hypoxia and Post-Radiation Reoxygenation to Cancer Cell Invasion: An HIF-Dependent Mechanism Background and Motivation Prior studies have extensively demonstrated that cancer cells in solid tumors acquire malignant characteristics such as invasiveness and treatment resistance under hypoxic condit...

Tumour Microenvironment-Mediated Drug Resistance in Neuroblastoma

Background Research Background: Both intrinsic and extrinsic factors in the tumor microenvironment (TME) can lead to treatment resistance. This paper reveals that the Transforming Growth Factor (TGF)-β1 produced within the TME increases drug resistance in neuroblastoma (NB) cells. Drug resistance is the main cause of cancer treatment failure, usual...

Plasma Membrane Damage Limits Replicative Lifespan in Yeast and Induces Premature Senescence in Human Fibroblasts

Scientific Research Report: Plasma Membrane Damage Limits Yeast Replicative Lifespan and Induces Premature Senescence in Human Fibroblasts Background and Research Motivation Plasma Membrane Damage (PMD) is a phenomenon experienced by all cell types in response to environmental disturbances and spontaneous cellular activities. Previous studies have ...

HLA-A+ Tertiary Lymphoid Structures with Reactivated Tumor-Infiltrating Lymphocytes Are Associated with a Positive Immunotherapy Response in Esophageal Squamous Cell Carcinoma

In esophageal squamous cell carcinoma (ESCC), immune checkpoint blockade (ICB) therapy has achieved significant clinical benefits. However, the overall response rate to ICB treatment remains low. This study aims to identify biomarkers for ESCC response to ICB therapy and explore their potential clinical relevance. The authors of the paper come from...
