Liver Int

February 2025

General Practice Ward/International Medical Center Ward, General Practice Medical Center, West China Hospital, Sichuan University, Chengdu, China.

Background And Aims: Cirrhosis is characterised by hyperdynamic circulation, which contributes to cirrhotic cardiomyopathy (CCM). However, the expert consensus on CCM did not initially include cardiac structure because of scant evidence. Therefore, this study investigated the associations of cardiac chamber geometry with mortality and CCM.

Therapeutic effect of fully human anti-Nrp-1 antibody on non-small cell lung cancer in vivo and in vitro.

Cancer Immunol Immunother

January 2025

Public Center of Experimental Technology, The School of Basic Medical Sciences, Southwest Medical University, Luzhou, 646000, Sichuan Province, China.

Although immune checkpoint inhibitors have changed the treatment paradigm for non-small cell lung cancer (NSCLC), not all patients benefit from them. Therefore, there is an urgent need to explore novel immune checkpoint inhibitors. Neuropilin-1 (Nrp-1) is a unique immune checkpoint capable of exerting antitumor effects through CD8 T cells.

Alpha-Glucosidase Inhibitors in Aging and Aging-Related Diseases: Clinical Applications and Relevant Mechanisms.

Aging Dis

January 2025

Department of Endocrinology and Metabolism, Department of Biotherapy, Laboratory of Diabetes and Metabolism Research, State Key Laboratory of Biotherapy and Cancer Center, West China Hospital, Sichuan University, Chengdu, 610041, Sichuan, China.

Aging is a complex and universal process marked by gradual functional declines at the cellular and tissue levels, often leading to a range of aging-related diseases such as diabetes, cardiovascular diseases, and cancer. Delaying the aging process can help prevent, slow down, and alleviate the severity of these various conditions, enhancing overall health and well-being. Alpha-glucosidase inhibitors (AGIs) are a class of widely used antidiabetic drugs that inhibit alpha-glucosidase in the small intestinal mucosa, delaying carbohydrate absorption and reducing postprandial hyperglycemia.

Hydrogels are promising materials for wearable electronics, artificial skins and biomedical engineering, but their limited stretchability, self-recovery and crack resistance restrict their performance in demanding applications. Despite efforts to enhance these properties using micelle cross-links, nanofillers and dynamic interactions, it remains a challenge to fabricate hydrogels that combine high stretchability, self-healing and strong adhesion. Herein, we report a novel hydrogel synthesized the copolymerization of acrylamide (AM), maleic acid (MA) and acrylonitrile (AN), designed to address these limitations.

Anisotropic Nanofluidic Ionic Skin for Pressure-Independent Thermosensing.

ACS Nano

January 2025

College of Polymer Science and Engineering, Sichuan University, State Key Laboratory of Polymer Materials Engineering, Chengdu 610065 Sichuan, China.

Ionic skin can mimic human skin to sense both temperature and pressure simultaneously. However, a significant challenge remains in creating precise ionic skins resistant to external stimuli interference when subjected to pressure. In this study, we present an innovative approach to address this challenge by introducing a highly anisotropic nanofluidic ionic skin (ANIS) composed of carboxylated cellulose nanofibril (CNF)-reinforced poly(vinyl alcohol) (PVA) nanofibrillar network achieved through a straightforward one-step hot drawing method.

Esophageal cancer (ESCA) is a common tumor noted in the digestive tract, which is highly malignant due to unclear early symptoms and poor last‑stage treatment effects; its mortality rate is relatively high. MicroRNA (miR) and signal transducer and activator of transcription 3 (STAT3) are key components of cellular signaling pathways; their interaction forms a complex and intricate information network that controls several types of biological behaviors in the cells. In the tumor cell, these signal transduction pathways are abnormally active, indicating that the STAT3 signaling pathway mediated by miRs is involved in the progression of various cancer types.

Systematic low-grade chronic inflammation and intrinsic mechanisms in polycystic ovary syndrome.

Front Immunol

January 2025

Reproductive Endocrinology and Regulation Laboratory, West China Second University Hospital, Sichuan University, Chengdu, China.

Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder affecting 6-20% of women of childbearing age worldwide. Immune cell imbalance and dysregulation of inflammatory factors can lead to systematic low-grade chronic inflammation (SLCI), which plays a pivotal role in the pathogenesis of PCOS. A significant higher infiltration of immune cells such as macrophages and lymphocytes and pro-inflammatory factors IL-6 and TNF-α has been detected in PCOS organ systems, impacting not only the female reproductive system but also other organs such as the cardiovascular, intestine, liver, thyroid, brain and other organs.

A comprehensive understanding of tumor heterogeneity, tumor microenvironment and the mechanisms of drug resistance is fundamental to advancing breast cancer research. While single-cell RNA sequencing has resolved the issue of "temporal dynamic expression" of genes at the single-cell level, the lack of spatial information still prevents us from gaining a comprehensive understanding of breast cancer. The introduction and application of spatial transcriptomics addresses this limitation.
