Nitroxyl protects H9C2 cells from H/R-induced damage and inhibits autophagy via PI3K/Akt/mTOR pathway.
PLoS One
January 2025
Precision Laboratory of Vascular Medicine, Shanxi Cardiovascular Hospital Affiliated Shanxi Medical University, Taiyuan, PR China.
Background: Myocardial ischemia-reperfusion injury (MIRI) is an important complication in the treatment of heart failure, and its treatment has not made satisfactory progress. Nitroxyl (HNO) showed protective effects on the heart failure, however, the effect and underlying mechanism of HNO on MIRI remain largely unclear.
Methods: MIRI model in this study was established to induce H9C2 cell injury through hypoxia/reoxygenation (H/R) in vitro.
Bright and Specific Targeting of Metastatic Lymph Nodes in Orthotopic Mouse Models of Gastric Cancer with a Fluorescent Anti-CEA Antibody.
Ann Surg Oncol
January 2025
Department of Surgery, University of California San Diego, La Jolla, CA, USA.
Background: Gastric cancer poses a major diagnostic and therapeutic challenge. Improved visualization of tumor margins and lymph node metastases with tumor-specific fluorescent markers could improve outcomes.
Methods: To establish orthotopic models of gastric cancer, one million cells of the human gastric cancer cell line, MKN45, were suspended in 50 μl of equal parts PBS and Matrigel and injected into the nude mouse stomach with a 29-gauge needle.
Ginkgolide B regulates apoptosis, oxidative stress, and mitochondrial dysfunction in MPP-induced SK-N-SH cells by targeting HDAC4/JNK pathway.

Ginkgolide B (GB) is a bioactive constituent found in Ginkgo biloba leaves that has been long recognized as a protective agent against many neurological disorders. Our study aimed to examine the effect of GB in an in vitro Parkinson's disease (PD) model and to investigate its neuroprotective mechanism as a primary objective. SK-N-SH cells were challenged with 1-methyl-4-phenylpyridinium (MPP) to act as a PD-like model of neuronal damage.

Fluorescence polarization (FP) is a useful technique to study the interactions between carbohydrates and proteins in solution, by using standard equipment and minimal sample consumption. Here, we will review the most recent FP-based approaches in this field, including the study of carbohydrate-lectin, carbohydrate-enzyme and glycosaminoglycan-protein interactions. Advantages and limitations of this methodology will be discussed.

R. China.
A DNA strand-based fluorescent probe was developed for the direct simultaneous detection of small cell lung cancers' tumor markers NSE and ProGRP. The probe offers stability, simplicity, and rapid response, making it highly promising for application in clinical serum samples' diagnosis.
