As water-saturated polymer networks, the easy water loss of hydrogels directly affects their end-use applications. Minimizing the ratio of free water and increasing the ratio of bound water in the gel system has become key to extending the service life. In this work, an ionogel is prepared that effectively regulates the proportion of free water and bound water through the formation of wrinkle angles by the hydrophilic and hydrophobic chains in the gel system and the non-volatile nature of the ionic liquid.

Renal cell carcinoma is the most common type of primary renal cancer, and clear cell carcinoma is the most common subtype, accounting for approximately 70% of all adult renal cell carcinoma cases. At the time of diagnosis, many patients already have metastatic manifestations. Cutaneous metastasis of renal clear cell carcinoma is very rare and usually represents a poor prognosis, mostly affecting the head and neck.

Background: The vascular endothelial growth factor (VEGF) and microvessel density (MVD) have been widely employed as angiogenesis indicators in the diagnosis and treatment of soft tissue sarcomas. While diffusion kurtosis imaging (DKI) and proton magnetic resonance spectroscopy (H-MRS) imaging hold potential in assessing angiogenesis in other tumors, their reliability in correlating with angiogenesis in soft tissue sarcomas remains uncertain, contingent upon accurately acquiring the region of interest (ROI).

Methods: 23 patients with soft tissue sarcomas (STSs) confirmed by pathology were selected, underwent DKI and H-MRS at 3.

Article Synopsis
  • MACC1 is a newly identified factor in lung cancer that promotes the transition of non-cancer stem cells (non-CSCs) to cancer stem cells (CSCs), which play a key role in tumor growth.
  • High levels of MACC1 are found in stemness-enriched lung cancer cells, and reducing MACC1 expression through shRNA effectively halts this transition.
  • The study suggests that MACC1 stabilizes KLF4 mRNA by inhibiting microRNA-25, and understanding this relationship could lead to targeted therapies for cancer stem cells.

Article Synopsis
  • This study investigates the effect of conduction system pacing (CSP) on the occurrence of atrial high-rate episodes (AHREs) in heart failure patients with preserved ejection fraction (HFpEF), comparing it to right ventricular pacing (RVP).
  • Researchers analyzed data from 498 patients who received dual-chamber pacemakers between January 2018 and January 2023, noting both new-onset and progressive AHREs.
  • Findings indicate that CSP is associated with a significantly lower incidence of new-onset AHREs in patients without prior atrial fibrillation compared to RVP, and also showed improvements in various cardiac performance metrics following CSP.

Bladder cancer (BCa) is a heterogeneous malignancy characterized by distinct immune subtypes, primarily due to differences in tumor-infiltrating immune cells and their functional characteristics. Therefore, understanding the tumor immune microenvironment (TIME) landscape in BCa is crucial for prognostic prediction and guiding precision therapy. In this study, we integrated 10 machine learning algorithms to develop an immune-related machine learning signature (IRMLS) and subsequently created a deep learning model to detect the IRMLS subtype based on pathological images.

Elevated uptake of saturated fatty acid palmitic acid (PA) is associated with tumor metastasis; however, the precise mechanisms remain partially understood, hindering the development of therapy for PA-driven tumor metastasis. The Hippo-Yes-associated protein (Hippo/YAP) pathway is implicated in cancer progression. Here it is shown that a high-palm oil diet potentiates tumor metastasis in murine xenografts in part through YAP.

FcRn-dependent IgG accumulation in adipose tissue unmasks obesity pathophysiology.

Cell Metab

December 2024

Department of Pharmacology, School of Basic Medical Sciences, State Key Laboratory of Vascular Homeostasis and Remodeling, Peking University, Beijing, China. Electronic address:

Immunoglobulin G (IgG) is traditionally recognized as a plasma protein that neutralizes antigens for immune defense. However, our research demonstrates that IgG predominantly accumulates in adipose tissue during obesity development, triggering insulin resistance and macrophage infiltration. This accumulation is governed by neonatal Fc receptor (FcRn)-dependent recycling, orchestrated in adipose progenitor cells and macrophages during the early and late stages of diet-induced obesity (DIO), respectively.

In the last decade, advancements in immunotherapy knowledge have highlighted CTLA-4, PD-1, LAG-3, TIM-3, and TIGIT, decisive immune checkpoints exhibiting within the tumor microenvironment (TME), as fundamental objects for cancer immunotherapy. The widespread clinical use of immune checkpoint inhibitors (ICls), employing PD-1/PD-L1 or CTLA-4 antibodies to obstruct crucial checkpoint regulators, is noted in treating B-cell lymphoma patients. Nevertheless, the prolonged advantages of the currently employed treatments against CTLA-4, PD-1, and PD-L1 are uncommon among patients.
