Int J Biol Macromol

December 2024

College of pharmacy, Xinxiang Medical University, 453003, Xinxiang, PR China; Pingyuan Laboratory, 453007, Xinxiang, Henan, PR China. Electronic address:

Effective delivery of sufficient doxorubicin (DOX) molecules in tumors is hindered by the complex biological barriers. Herein, a DOX-loaded sodium alginate-based injectable hydrogel (DOX@MHB-conj-SA) was designed by the Michael addition reactions between the sulfydryl in cross-linkers and the double bonds in a derivative of sodium alginate. The DOX@MHB-conj-SA was administrated to CT26 tumor-bearing mice via peritumoral injection for locoregional treatment of colorectal cancer by inducing apoptosis and pyroptosis.

Hidradenocarcinoma (HAC) is a rare neoplasm that typically occurs in the head and neck region but seldom affects the chest wall. Histopathology and immunohistochemistry remain essential for diagnosing HAC, although their clinical utility in determining metastasis can be limited. Given the pathological rarity and histopathological heterogeneity of HAC, we report a case demonstrating the utility of positron emission tomography/computed tomography (PET/CT) combined with immunohistochemical examination for the accurate diagnosis and staging of HAC.

Background: Mice play a crucial role in studying the mechanisms of general anesthesia. However, identifying reliable EEG markers for different depths of anesthesia induced by multifarious agents remains a significant challenge. Spindle activity, typically observed during NREM sleep, reflects synchronized thalamocortical activity and is characterized by a frequency range of 7-15 Hz and a duration of 0.

Pre-existing of pulmonary tuberculosis (PTB) poses increased lung cancer risk, yet the molecular mechanisms remain inadequately understood. This study sought to elucidate the potential mechanisms by performing comprehensive analyses of differentially expressed genes (DEGs) in peripheral blood mononuclear cells (PBMCs) from patients with PTB, lung adenocarcinoma (LUAD), and lung squamous cell carcinoma (LUSC). Microarray assays were employed to analyze the DEGs in PBMCs of these patients.

Background: The spleen, as the body's largest peripheral immune organ and a crucial source of circulating monocytes, plays a significant role in the acute inflammatory response of spleen-derived macrophages to diseases. Therefore, studying the impact and mechanism of X-ray irradiation on spleen-derived macrophages' inflammatory responses is of great importance.

Method: Extracted and identified mice splenic macrophages were divided into four groups: control group, LPS and ATP co-stimulated non-irradiated group, LPS and ATP co-stimulated group irradiated after 6 h, and LPS and ATP co-stimulated group irradiated after 12 h In the LPS and ATP co-stimulated groups, LPS (1μg/ml) and ATP (5mmol/L) were added to establish an inflammatory model in mice splenic macrophages.

January 2025

Department of General Surgery, Affiliated Hospital of Zunyi Medical University, Zunyi, China; Department of Thyroid and Breast Surgery, Affiliated Hospital of Zunyi Medical University, Zunyi, China. Electronic address:

Breast cancer is the most prevalent malignant tumour among women. Approximately 70 % of patients are hormone receptor (HR)-positive and undergo endocrine therapy as the main form of treatment; however, the efficacy of this type of therapy is limited by some factors, such as drug resistance and complex tumour microenvironments. Using network pharmacology and molecular docking, this study examined how CDK4/6 inhibitors enhance the effects of immunotherapy for HR-positive breast cancer, focusing on their effects on the tumour microenvironment (TME) and immune cell activity.

Metabolic dysfunction-associated steatotic liver disease (MASLD) causes cellular senescence due to oxidative stress, endoplasmic reticulum stress, and ectopic fat deposition in the liver. Recently, dasatinib, an antitumor agent, and quercetin, a dietary supplement, were combined as a senolytic drug to eliminate senescent cells. Thus, this study aimed to examine the effects of dasatinib and quercetin administration on removing senescent cells and their therapeutic effects on MASLD in a medaka MASLD model.

Background: To explore the mechanism of hyperbaric oxygen (HBO) intervention on acute lung injury secondary to snake venom poisoning and provide more toxicological and clinical evidence for venom poisoning.

Methods: Male Kunming mice (n = 96) were randomly divided into four groups: the control group which was not given any interventional treatments, venom group in which each mouse was injected with venom (1 mg/kg) through the tail vein, antivenom group in which each mouse was injected with anti- venom immediately after the model was successfully established, and HBO+antivenom group in which each mouse was given HBO treatment at 1 h, 5 h, 11 h and 23 h following the injection of antivenom. Lung tissues of mice were obtained and processed for the detection of the lung coefficient, the levels of inflammatory factors such as interleukin (IL)-6, IL-10 and IL-17, and the protein expression of retinoic acid receptor (RAR)-related orphan receptor gamma (RORγt) and forkhead box P3 (FOXP3).

Aldosterone-producing adenoma (APA) is a leading cause of primary aldosteronism (PA), a condition marked by excessive aldosterone secretion. CYP11B2, the aldosterone synthase, plays a critical role in aldosterone biosynthesis and the development of APA. Despite its significance, encoding regulatory mechanisms governing CYP11B2, particularly its degradation, remain poorly understood.

STING-Activating Polymers Boost Lymphatic Delivery of mRNA Vaccine to Potentiate Cancer Immunotherapy.

Adv Mater

December 2024

Department of Diagnostic Radiology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore, 119074, Singapore.

The unprecedented success of mRNA vaccines against COVID-19 has inspired scientists to develop mRNA vaccines for cancer immunotherapy. However, using nucleoside modified mRNA as vaccine, though evading innate immune toxicity, diminishes its therapeutic efficacy for cancers. Here, we report a polyvalent stimulator of interferon genes (STING) activating polymer (termed as PD) to bolster the immunogenicity of mRNA vaccine.
