“…researchers have pinpointed the protein that can lead to genetic changes that cause lung cancer…the production of a protein called FANCD2 is slowed when lung cells are exposed to cigarette smoke. Low levels of FANCD2 leads to DNA damage, triggering cancer. Cigarette smoke curbs the production of ‘caretaker’ proteins, like FANCD2, which normally prevent cancer by fixing damages in DNA and causing faulty cells to commit suicide…”…Although there are probably other proteins involved in this process, we know this is a key one because cells with very high levels of FANCD2 were resistant to the toxic effects of the smoke.”…” Full Slice
