Department of Bone and Soft Tissue Tumor Surgery, Cancer Hospital of Dalian University of Technology,Cancer Hospital of China Medical University, Liaoning Cancer Hospital & Institute, Shenyang, Liaoning Province, China.

Osteosarcoma (OS) is a prevalent primary malignant bone tumor, typically managed through a combination of neoadjuvant chemotherapy and surgical interventions. Recent advancements in early detection and the use of novel chemotherapeutic agents have significantly improved the 5-year survival rate of OS patients. However, some patients fail to achieve the desired treatment outcomes despite undergoing intensive chemotherapy and surgicals procedures, with chemotherapy resistance emerging as a critical factor contributing to therapeutic failure in OS.

Non-small cell lung cancer (NSCLC) is the predominant form of lung cancer and poses a significant public health challenge. Early detection is crucial for improving patient outcomes, with serum biomarkers such as carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCAg), and cytokeratin fragment 19 (CYFRA 21-1) playing a critical role in early screening and pathological classification of NSCLC. However, due to being mainly based on corresponding antibody binding reactions, existing detection technologies for these serum biomarkers have shortcomings such as complex operations, high false positive rates, and high costs.

Oral Lactoferrin-Responsive Formulation Anchoring around Inflammatory Bowel Region for IBD Therapy.

Adv Healthc Mater

December 2024

Department of Oncology, The Second Affiliated Hospital, Medical School of Xi'an Jiaotong University, Xi'an, Shaanxi, 710061, China.

Oral formulation is the ideal treatment method for inflammatory bowel disease (IBD) therapy, but the mucosal damage and diarrhea symptoms impede the drug retention around the inflammatory region, severely limiting IBD therapeutic efficacy. To address this, an oral astaxanthin (Ast) precise delivery formulation is developed with the selective Ast anchoring around the inflammatory region by the novel lactoferrin (LF)-responsive flocculation. This formulation also heightens the apparent solubility of Ast with the minimized edible safety risks for the edible raw materials.

Cancer Hospital of China Medical University, Liaoning Cancer Hospital and Institute, Cancer Hospital of Dalian University of Technology, Faculty of Medicine, Dalian University of Technology, Shenyang 110042, Liaoning, China.

Stem cell therapy is a novel approach for treating various severe and intractable diseases, including autoimmune disorders, organ transplants, tumors, and neurodegenerative diseases. Nevertheless, the extensive utilization of stem cells is constrained by potential tumorigenicity, challenges in precise differentiation, rejection concerns, and ethical considerations. Extracellular vesicles possess the ability to carry diverse bioactive factors from stem cells and deliver them to specific target cells or tissues.

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.

Pro-viral Insertion site for the Moloney Murine Leukemia virus 1 (PIM-1) is widely involved in various biological processes and diseases, which is based on its structure and functional sites. However, the relationship between active sites and function of PIM-1 kinase remains unclear due to the lack of effective study approaches in live cells. Herein, to visualize the effect of different active sites in PIM-1 protein on its function activity and relation with PI3K/Akt/mTOR pathway, three mutant probes of EPHY which was developed previously based on fluorescence resonance energy transfer (FRET) technology to detect PIM-1 kinase activity in living cells were further constructed and transfected into cells followed by treating with PIM-1 inhibitors, ATP and PI3K inhibitor, respectively.
