Figure Lengend Snippet: Biochemical structures of Linebacker-1 (LB1) and myricetin and antineoplastic effect of LB1 with/without radiation in human colon and lung cell lines. (A) Myricetin (left) and LB1 (right) showing with a red circle for the OH ion’s replacement by a cloride ion (Cl). (B) Schematic diagram of the treatment design using LB1 for in vitro study. (C) and (D) MTT growth assay using OD value 570 nm, showing the antitumor effect of LB1 in titrated doses for both human colon (HT29) and lung (A549) cancer cell lines, respectively. (E) Bar graph representing the colony count numbers from the clonogenic survival assay after LB1 treatment. (F) Schematic diagram showing the treatment design for in vitro LB1 and radiation treatment. Doses of 0, 25, 50, and 75 µM LB1, along with single radiation fractions of 0, 2, 4, and 6 Gy, were used in the clonogenic survival study. (G) For the clonogenic survival assay, colony counts are shown for A549 cells treated with 0, 2, 4, and 6 Gy of radiation, with or without LB1, at 0, 25, 50, and 75 µM. (H) colony count for A549 and Lewis lung carcinoma (LLC1) cell line , respectively. Graphs are generated from the average of at least 3 study repeats. The SD of the multiple independent repeats is shown, while statistical significance is shown by *** P < .001. Abbreviation : OD = optical density; OH = hydroxide ion; MTT = methyl dimethylthiazol diphenyltetrazolium bromide; RT = radiation therapy.

Article Snippet: A549 cells were cultured in RPMI cell culture media (Gibco), the HT29 cell line was cultured in McCoy’s 5A medium (ATCC), and the LLC1 cell was cultured in Dulbecco’s Modified Eagle Media (Gibco).

Figure Lengend Snippet: Killing effect of recombinant oHSV-1 on colon cancer cells (A–C) CT26 (A), HCT116 (B), and HT29 (C) colon cancer cells were infected with recombinant oncolytic virus at multiplicity of infection (MOI) of 0.5, 1, and 5, respectively. The cell killing rate was detected by cell counting kit-8 (CCK8) assay 48 h after infection. The results showed that the killing effect of the virus on the three colon cancer cells was enhanced in an MOI - dependent manner. (D–F) CT26 (D), HCT116 (E), and HT29 (F) cells were infected with recombinant oncolytic virus at MOI = 1. The killing rate was measured by CCK8 assay at 24, 48, and 72 h after infection, suggesting that the killing effect of the virus on colon cancer cells was significantly enhanced with the prolongation of action time.
