RH1 (2, 5-diaziridinyl-3-(hydroxymethy)-6-methyl-1, 4-benzoquinone) is a bioreductive anticancer drug. The mechanism underlying its therapeutic properties has not yet been elucidated. In this study, we aimed to determine whether RH1 exerts its anticancer effect via p53-mediated apoptosis and senescence in vitro and in vivo. RH1 displayed dose-dependent biphasic effects in vitro, i.e., it induced apoptosis at higher dose and senescence at lower dose accompanied by marked activation of p53. Thus, ...

Purpose Several clinical trials have combined antiangiogenic agents and radiation therapy (RT), but evidence of its clinical benefit is insufficient. In this study, we rationalized and investigated the combination of vascular endothelial growth factor-Grab (VEGF-Grab), an antiangiogenic drug that inhibits VEGF-A and placental growth factor (PlGF) and radiotherapy for anti-cancer therapy. Methods and Materials To observe for changes in PlGF after radiation, HCT116, HCT15, SW480, BxPC3, and RAW264...

Germline BRCA1 mutations predispose women to breast and ovarian cancer. BRCA1, a large protein with multiple functional domains, interacts with numerous proteins involved in many important biological processes and pathways. However, to date, the role of BRCA1 interactions at specific stages in the progression of mammary tumors, particularly in relation to cell cycle regulation, remains elusive. Here, we demonstrate that BRCA1 interacts with cyclin B1, a crucial cell cycle regulator, and that the...

Neoadjuvant radiotherapy is becoming an important therapeutic option for colorectal cancer (CRC) patients, although complete tumor response is observed only in 20 to 30% patients. However, precise biologic mechanisms underlying resistance to radiotherapy remain to be elucidated. In this study, we established a radiotherapy-resistant CRC patient-derived xenograft (PDX) mouse model, and we discovered that low-density lipoprotein receptor-related protein-1 (LRP-1) is increased in radiotherapy-resis...

Backgrounds Since most patients with castration-resistant prostate cancer (CRPC) develop resistance to its standard therapy docetaxel, many studies have attempted to identify novel combination treatment to meet the large clinical unmet need. In this study, we examined whether histone deacetylase inhibitors (HDACIs) enhanced the effect of docetaxel on AR signaling in CRPC cells harboring AR and its splice variants. Methods HDACIs (vorinostat and CG200745) were tested for their ability to enhance ...

Abstract Bio-nanocapsules (BNCs) consisting of hepatitis B virus surface antigen (HBsAg) L proteins and phospholipids are used as efficient non-viral carriers for liver-specific delivery of genes and drugs. Considering the administration to HB vaccinees and HB patients, endogenous anti-HBsAg immunoglobulins (HBIGs) may reduce the delivery efficacy and prevent repetitive administration. Therefore, low immunogenic BNCs were generated by inserting two point mutations in the HBsAg L protein, which w...
