AI Article Synopsis

  • Agaricus blazei Murill (ABM) extract is a dietary supplement, but its effects on chemotherapeutic agents are not well understood.
  • The study tested ABM extract's impact on the effectiveness of several chemotherapy drugs in cervical cancer cells, including both sensitive and drug-resistant strains.
  • Results showed that ABM extract did not inhibit cell growth or change sensitivity to most drugs, but it did decrease sensitivity to doxorubicin in drug-resistant cells.

Article Abstract

Agaricus blazei Murill (ABM; Japanese name: Kawahiratake or Agarikusutake) extract is a widely used dietary supplement. However, limited information is available on the effects of the extract on the effectiveness of the chemotherapeutic agents. In this study, we examined the effects of ABM extract (Kyowa Wellness Co., Ltd.) on sensitivity to chemotherapeutic agents, paclitaxel and doxorubicin as MDR1/P-glycoprotein substrates, and cisplatin and 5-fluorouracil as non-substrates, in human cervical carcinoma HeLa cells, and paclitaxel-resistant and cisplatin-resistant derivatives (HeLa/TXL and HeLa/CDDP, respectively). The extract had no growth inhibitory effects on HeLa and the resistant cells at concentrations ranging from 7.6 × 10(-4) μ g/ml to 8.0 × 10(2)μ g/ml, indicating no remarkable cytotoxic activity in vitro. In the presence of 0.1, 0.5, and 1 μ g/ml of ABM extract, sensitivity to paclitaxel, cisplatin and 5-fluorouracil did not change in HeLa, HeLa/TXL and HeLa/CDDP cells. However, the extract reduced sensitivity to doxorubicin in HeLa/TXL and HeLa/CDDP cells in a concentration-dependent manner. In conclusion, the concomitant use of ABM extract minimally affected sensitivity to various chemotherapeutic agents in HeLa cells and resistant sublines in vitro.

Despite the development of various controlled release systems for antitumor therapies, off-target side effects remain a persistent challenge. In situ therapeutic synthesis from biocompatible substances offers a safer and more precise alternative. This study presents a hypoxia-initiated supramolecular free radical system capable of inducing intracellular polymerization, thereby disrupting the cytoskeleton and organelles within 4T1 cells.

Camptothecin (CPT), a chemotherapeutic agent, demonstrates significant potential in cancer therapy. However, as a drug, CPT molecule suffers from poor water solubility, limited bioavailability, and insufficient immune response. Herein, we construct CPT nanofibers (CNF) with a right-handed chiral property via supramolecular self-assembly, which significantly overcomes the solubility barriers associated with bioavailability and improves tumor immune prognosis.

Drug resistance is a major challenge in cancer therapy that often leads to treatment failure and disease relapse. Despite advancements in chemotherapeutic agents and targeted therapies, cancers often develop drug resistance, making these treatments ineffective. Extracellular vesicles (EVs) have gained attention for their potential applications in drug delivery because of their natural origin, biocompatibility, and ability to cross biological barriers.
