doi: 10.3892/or.2026.9063
Figure Lengend Snippet: TRIM46 upregulation contributes to DDP resistance in non-small cell lung cancer cells. (A) RT-qPCR (left) and western blot (right) analysis of TRIM46 expression in 16HBE, A549 and A549/DDP cells. (B) RT-qPCR (left) and western blot (right) analysis of TRIM46 expression in A549 cells infected with TRIM46 overexpression lentivirus. (C) Cell apoptosis was measured after transduction with TRIM46-overexpression lentivirus and/or DDP treatment (0, 5 and 10 µM) in A549 cells. (D) Quantitative analysis of cell apoptosis. (E) Representative images of the comet assay showing DNA fragmentation after transduction with TRIM46-overexpression lentivirus and/or DDP treatment (0, 5 and 10 µM) in A549 cells (scale bar, 50 µm; magnification, ×400). (F) Quantification of tail DNA (%) revealing DNA damage after transduction with TRIM46-overexpression lentivirus and/or DDP treatment (0, 5 and 10 µM) in A549 cells. *P<0.05, **P<0.01, ***P<0.001. TRIM46, tripartite motif 46; DDP, cisplatin; RT-qPCR, reverse transcription-quantitative polymerase chain reaction; PI, propidium iodide.
Article Snippet: The shRNA sequences targeting TRIM46 (shTRIM46-1, 5′-GGTGAGGATATGCAGACCT-3′; shTRIM46-2, 5′-GATATGCAGACCTTCACTT-3′; and shTRIM46-3, 5′-AGACCTTCACTTCCATCAT-3′), as well as the shNC (5′-GATACATACTAGATCGACT-3′) vector, were purchased from Shanghai GeneChem Co., Ltd and engineered into the pLKO.1 puro lentiviral vector (Addgene, Inc.).
