WebApr 22, 2024 · Cisplatin delivers its attack by entering cancer cells and binding to and damaging DNA, which can lead to cell death. Cells respond to DNA damage by triggering … WebJan 1, 2024 · After cisplatin enters the cells, the chloride ligands are replaced by water molecules. This reaction results in the formation of positively charged platinum complexes that form covalent bonds with nucleophilic sites on guanine bases in a DNA strand using intrastrand and interstrand cross-links and create cisplatin–DNA adducts.
WebTreatment of lung cancer, the most common type of carcinoma, is difficult due to disease progression at the time of diagnosis, causing a high mortality rate. 1 , 32 Cisplatin (DDP), also known as cis‐diaminodichloplatin, is a powerful nonspecific drug blocking the cell cycle. 33 , 34 DDP can enter cells through the passive transport. WebThe present study aimed to examine whether AT-101 could increase the sensitivity of non-small cell lung cancer A549 cells to cisplatin (CDDP) and the underlying mechanisms. We evaluated the efficacy of the sequential treatment with AT-101 and CDDP using both in vitro and in vivo models.
WebThe cells are most sensitive to cisplatin in this phase of the cell cycle. As far as the development of targeted agents is concerned, inhibition of the cell cycle in G1/S phase is likely to result in a protective effect against cisplatin, whereas agents arresting cells in G2/M may exert a synergistic effect. WebIf cisplatin is aquated and acquires a charge outside of the cell, it is likely that it enters the cell via OCT1, an organic cation transporter, or CTR1, a copper (I) transporter. [1] Both OCT1 and CTR1 transport charged species …
