Article Synopsis
  • Gelatin hydrogels, like GelMA gels, are popular in tissue engineering for their degradability and ability to support cell adhesion but struggle with mechanical performance due to a single network structure.
  • A new hydrogel is created using a phototriggered reaction, resulting in a phase-separated structure that enhances interfacial bonding and improves mechanical strength compared to traditional GelMA gels.
  • This innovative hydrogel maintains gelatin's beneficial properties and broadens its usage potential in advanced biomedical applications, particularly in 3D printing and other biofabrication technologies.

Article Synopsis
  • Existing methods to study the antitumor effects of artemisinin (ART) are insufficient, as they often overlook the interaction between free Fe(II) and heme as activators of ART.
  • A new drug delivery system using transferrin-modified hollow mesoporous silica nanoparticles is introduced, which incorporates a functional ART derivative, glucose oxidase, and perfluoropentane to enhance the effectiveness of Fe(II)-ART-mediated chemodynamic therapy (CDT).
  • This innovative approach combines starvation therapy and Fenton reaction to efficiently provide Fe(II) to ART, targeting mitochondria and improving its anticancer effectiveness, thereby showing promise for future cancer treatments.

Tenascin C (TNC), a rich glycoprotein of the extracellular matrix, exhibits a pro-atherosclerosis or anti-atherosclerosis effect depending on its location. TNC, especially its C domain/isoform (TNC-C), is strongly overexpressed in atherosclerotic plaque active areas but virtually undetectable in most normal adult tissues, suggesting that TNC is a promising delivery vector target for atherosclerosis-targeted drugs. Many delivery vectors were investigated by recognizing TNC-C, including G11, G11-iRGD, TN11, PL1, and PL3.

The glucose transporter 1 (GLUT1) protein is involved in the basal-level absorption of glucose in tumor cells. Inhibiting GLUT1 decreases tumor cell proliferation and induces tumor cell damage. Natural GLUT1 inhibitors have been studied only to a small extent, and the structures of known natural GLUT1 inhibitors are limited to a few classes of natural products.

Context: Osteoporosis (OP) is a common complication for patients who have liver cirrhosis or cholestatic liver disease or who have received a liver transplantation. Osteoporotic fractures are serious clinical consequences of OP, and they often occur in the spine, hip, and wrist; have a high disability and mortality rate; cause a serious, social, medical burden; and threaten people's health.

Objective: The study intended to explore the correlation between different degrees of liver fibrosis and bone mineral density (BMD) of the lumbar spine and hip as well as the factors influencing those differences.

The association between acrylamide (AA) and the development of cancer has been extensively discussed but the results remained controversial, especially in population studies. Large prospective epidemiological studies on the relationship of AA exposure with cancer mortality were still lacking. Therefore, we aimed to assess the association between AA biomarkers and cancer mortality in adult population from National Health and Nutrition Examination Survey (NHANES) 2003-2014.

With the development of redox-related therapy modalities in cancer therapy, photodynamic therapy (PDT) has gradually become the most widely used type in the clinic. However, the hypoxic tumor microenvironment restricted the curative effect of PDT. Here, a strategic hypoxia relief nanodrug delivery system (SHRN) with a synergetic strategy was designed to alleviate tumor hypoxia on the basis of PDT.

With the development of precision medicine, visual and traceable treatments are highly desirable for cancer therapy. However, researchers and clinicians remain confused regarding where the drug distributes and location of the tumor, when the drug is released and when to irradiate the tumor, and how the drug presents antitumor activity, all of which hinders assessment of the cancer patient's condition and formulation of a follow-up treatment scheme for clinicians. Here, a supramolecular self-assembly theranostic nanosystem (MWNs) was designed for enhanced reactive oxygen species (ROS)-mediated cell apoptosis guided by dual-modality tumor imaging.

: Integration of several monotherapies into a single nanosystem can produce remarkable synergistic antitumor effects compared with separate delivery of combination therapies. We developed near-infrared (NIR) light-triggered nanoparticles that induce a domino effect for multimodal tumor therapy. : The designed intelligent phototriggered nanoparticles (IPNs) were composed of a copper sulfide-loaded upconversion nanoparticle core, a thermosensitive and photosensitive enaminitrile molecule (EM) organogel shell loaded with anticancer drugs, and a cancer cell membrane coating.

On-demand therapy following effective tumor detection would considerably reduce the side effects of traditional chemotherapy. DT-diaphorase (DTD), whose level is strongly elevated in various tumors, is a cytosolic flavoenzyme that promotes intracellular reactive oxygen species (ROS) generation via the redox cycling of hydroquinones. Incorporation of the DTD-responsive substrate to the structures of the probe and prodrug may facilitate the tumor detection and therapy.

Lysine-specific histone demethylase 1 (LSD1) was the first histone demethylase identified in epigenetics and has recently emerged as an attractive therapeutic target for treating tumors. To date, almost all reported LSD1 inhibitors have been chemosynthesized; however, natural products possess pharmacological and biological activity and can be sources for drug development. Here, we established a target separation countercurrent chromatography technique to isolate LSD1 inhibitors from zedoary turmeric oil.

Background: The ABRA C-terminal like (ABRACL) protein belongs to a novel family of low-molecular weight proteins that increase actin dynamics and cell motility. It is involved in various diseases including cancer; however, its role in gastric cancer is unclear. In this study, the expression of ABRACL in gastric cancer and its relationships with patients' clinicopathological features and survival are examined.

Previously, certain experiments have suggested that density-regulated re-initiation and release factor () could serve important roles in cancer, however, to the best of our knowledge, a comprehensive analysis of and its association with cancer patient survival is lacking. The aim of the current study was to investigate the expression of in multiple tumour types and to evaluate the effects of on survival in malignancies. Sample expression profiles were downloaded from the Gene Expression Omnibus database.
