    • Based polymer nanoparticles from bee pollen attenuate non-small lung cancer through enhancement of apoptosis and cell cycle arrest in vivo
    Authors: Salim, Elsayed I.; Mahfouz, Magdy E.; Eltonouby, Eman A.;  Advisor: -;  Co-Author: - (2023)

    Bee pollen extract (BPE)-based polymer nanoparticles (BPENP) were fabricated using bovine serum albumin (BSA) and targeted with folic acid and were further characterized. Mice groups are: Group 1 received saline, whereas Groups 2, 3, 4, 5, and 6 received a single dose of urethane, followed by weekly injections of butylated hydroxy-toluene (BHT). After the BHT injection, the mice in Groups 3, 4, 5, and 6 received BPE, Avastin, BPENP, and BPENP + Avastin, respectively. The number and size of tumors were decreased in Group 6 compared to those in the other groups. The ratios of early and late apoptotic cells in Groups 3, 4, 5, and 6 (42.8%, 41.4%, 26.2%, and 45.4%, respectively) were higher than that in the untreated group. The PCNA-labeling indexes (LI)% in tissues and lesions from Gro...
