Metabolic reprogramming of tumor cells dynamically reshapes the distribution of nutrients and signals in the tumor microenvironment (TME), affecting intercellular interactions and resulting in metabolic immune suppression. Increased glucose uptake and metabolism are characteristic of many tumors. Meanwhile, the progression of colorectal carcinoma (CRC) relies on lipid metabolism.

January 2024

National Clinical Research Center for Metabolic Diseases, Metabolic Syndrome Research Center, Key Laboratory of Diabetes Immunology, Ministry of Education, and Department of Metabolism and Endocrinology, The Second Xiangya Hospital of Central South University, Changsha, Hunan 410011, China.

Although loneliness and social isolation are proposed as important risk factors for metabolic diseases, their associations with the risk of non-alcoholic fatty liver disease (NAFLD) have not been elucidated. The aims of this study were to determine whether loneliness and social isolation are independently associated with the risk of NAFLD and to explore potential mediators for the observed associations. In this large prospective cohort analysis with 405,073 participants of the UK Biobank, the status of loneliness and social isolation was assessed through self-administrated questionnaires at study recruitment.

January 2025

Key Laboratory for Biorheological Science and Technology of Ministry of Education, State and Local Joint Engineering Laboratory for Vascular Implants, Bioengineering College of Chongqing University, Chongqing University Three Gorges Hospital, Chongqing, 400044, China.

Theranostic applications in atherosclerosis plaque microenvironment-triggered nanoplatforms are significantly compromised by the complex synthesis procedure, non-specific distribution, and limited therapeutic function. Therefore, development of a facile and feasible method to construct a pathology-based stimuli-responsive nanoplatform with satisfactory theranostic performance remains a demanding and highly anticipated goal. Herein, a novel class of multifunctional supra-carbon dots (CDs), denoted as MM@Ce-CDs NPs, by a simple nanoassembly and a subsequent coating with macrophage membrane (MM), is developed for the targeted reactive oxygen species-trigged theranostic and positive regulation of the pathological plaque microenvironment in AS.

Institute of Burn Research, Southwest Hospital, State Key Lab of Trauma and Chemical Poisoning, Army Medical University (Third Military Medical University), Chongqing 400038, China.

Chronic diabetic wounds present significant treatment challenges due to their complex microenvironment, often leading to suboptimal healing outcomes. Hydrogen sulfide (HS), a crucial gaseous signaling molecule, has shown great potential in modulating inflammation, oxidative stress and extracellular matrix remodeling, which are essential for effective wound healing. However, conventional HS delivery systems lack the adaptability required to meet the dynamic demands of different healing stages, thereby limiting their therapeutic efficacy.

Article Synopsis
  • RSA is linked to metabolic imbalances at the maternal-fetal interface, especially concerning essential fatty acids and oxylipins, which may contribute to the risk of spontaneous abortion.
  • Research involved analyzing samples from women experiencing spontaneous abortion and those with normal pregnancies, measuring fatty acid levels and enzyme expressions using advanced techniques like GC-MS and LC-MS.
  • Findings showed that women with recurrent spontaneous abortion had higher omega-6 fatty acid levels in their plasma and chorionic villi but lower levels in the decidua, suggesting a possible dysregulation of fatty acid transport affecting pregnancy outcomes.

Background & Aims: Current prognostic models for patients with hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE) are not extensively validated and widely accepted. We aimed to develop and validate a continuous model incorporating tumor burden and biology for individual survival prediction and risk stratification.

Methods: Overall, 4,377 treatment-naive candidates for whom TACE was recommended, from 39 centers in five countries, were enrolled and divided into training, internal validation, and two external validation datasets.

Acute Myeloid Leukemia (AML) are challenging blood cancers with limited long-term survival rates, necessitating novel therapeutic strategies. This study explored the role of Histone deacetylase (HDAC) inhibitors in enhancing ferroptosis in AML cells by modulating iron metabolism. We demonstrated that HDAC inhibitors (Entinostat and Vorinostat) sensitize AML cells to ferroptosis both in vitro and in vivo.

IGF2-IGF1R signaling inhibition delays the growth of IGF2-high colorectal cancer by modulating MDSCs.

Institute of Cancer, Xinqiao Hospital, Third Military Medical University, Chongqing, 400037, China; Department of Oncology, PLA Rocket Force Characteristic Medical Center, Beijing, 100088, China. Electronic address:

Approximately 22 % of human colorectal cancers (CRC) are characterized by IGF2 overexpression, and the tumor-promoting role of IGF2 has been widely reported. Despite promising preclinical results, IGF2 signaling inhibition therapy has exhibited limited efficacy in treating unselected patients with CRC. Recent evidence suggests that IGF2-high CRC are more sensitive to IGF2 signaling blockade therapy in immune-deficient mice, suggesting that IGF2-high CRC can benefit from IGF2 signaling blockade therapy.

Background: Radical cystectomy (RC) combined with pelvic lymph node dissection (PLND) is the standard treatment for muscle-invasive bladder cancer (MIBC). For metastatic MIBC patients, platinum-based chemotherapy remains the first choice treatment. However, approximately 50% of patients with metastatic MIBC are ineligible for platinum-based adjuvant chemotherapy because of impaired renal function.
