Fig. 1From: Unveiling the mechanisms and challenges of cancer drug resistanceCancer cell and drug-resistant cancer cell response to an anti-cancer drug. Chemotherapeutic drugs are effective on cancer cells as they enter into the cells and activate various anti-cancer pathways, leading to DNA damage and cell death. In resistant cells, cancer cells modulate drugs or produce a barrier to them which collectively resulted in decreasing their effectivity on cancer cells.
