Use of Iontophoresis Technology for Transdermal Delivery of a Minimal mRNA Vaccine as a Potential Melanoma Therapeutic
Biol Pharm Bull. 2023;46(2):301-308. doi: 10.1248/bpb.b22-00746.ABSTRACTmRNA vaccines have attracted considerable attention as a result of the 2019 coronavirus pandemic; however, challenges remain regarding use of mRNA vaccines, including insufficient delivery owing to the high molecular weights and high negative charges associated with mRNA. These characteristics of mRNA vaccines impair intracellular uptake and subsequent protein translation. In the current study, we prepared a minimal mRNA vaccine encoding a tumor associated antigen human gp10025-33 peptide (KVPRNQDWL), as a potential treatment for melanoma. Minimal mRNA...

Cathepsin G-Induced Cell Aggregation of Breast Cancer MCF-7 Decreases Doxorubicin Sensitivity in a Hypoxia-Inducible Factor-Independent Mechanism
Biol Pharm Bull. 2022;45(12):1772-1783. doi: 10.1248/bpb.b22-00447.ABSTRACTSolid tumors habitually harbor regions with insufficient oxygen away from vasculature. Hypoxia is an important factor that confers malignant phenotypes like chemoresistance to tumor cells. We have demonstrated that cathepsin G (CG) stimulates cell aggregation in breast cancer MCF-7 cells by activating insulin-like growth factor-1 signaling. We investigated whether cancer cell aggregates induced by CG acquire hypoxia-dependent chemoresistance. Pimonidazole staining and hypoxia-inducible factor (HIF)-1α and -2α expression indicated that the core of ...

RUNX2 Mediates Renal Cell Carcinoma Invasion through Calpain2
In this study, RUNX2-negative A498 cells and strongly positive ACHN cells were selected as the study subjects. An invasion chamber assay was used to detect the invasive ability of the cells. The expression of each protein was detected by Western blotting or immunofluorescence assays. The invasive ability of A498 cells was enhanced after the expression of RUNX2 protein was upregulated, whereas ACHN cells decreased after the expression of RUNX2 protein was silenced. The expression of calcium-activated neutral protease 2 (Calpain2) and fibronectin (FN) proteins was upregulated in A498 cells overexpressing RUNX2 protein, where...
