Cervical carcinoma has the highest incidence among gynaecological cancers in developing countries where the human papillomavirus (HPV) vaccine is not yet widely used. Cancer stem cells (CSCs) are the key factors affecting treatment efficacy and cancer prognosis. Aldehyde dehydrogenase 1 (ALDH1) is a marker of CSCs, and its expression is closely related to chemotherapy resistance in cervical carcinoma.

SnoRNAs: The promising targets for anti-tumor therapy.

J Pharm Anal

November 2024

Department of Pharmacology, School of Pharmacy, China Medical University, Shenyang, 110122, China.

In this study, the trastuzumab-functionalized SK-BR-3 cell membrane-wrapped mesoporous silica nanoparticles loaded with pyrotinib (Tra-CM-MSN-PYR) were prepared for targeted therapy of HER2-positive breast cancer. Transmission electron microscopy (TEM) characterization showed that MSN had a spherical morphology with mesoporous channels and that the structure of Tra-CM-MSN was a cell membrane (CM) layer successfully coated on the surface of MSN. A cellular uptake assay demonstrated that FITC-labeled Tra-CM-MSN were taken up by SK-BR-3 breast cancer cells, which illustrated that Tra-CM-MSN had good targeting ability compared with CM-MSN and MSN.
