Lung cancer is one of the most common causes of cancer-related death worldwide in men and women, and, despite the recent remarkable scientific advances, drug treatment is still unsatisfactory. Polycomb protein
chromobox homolog 7
(
CBX7
) is involved in several biological processes, including development and cancer progression, indeed the lack of
CBX7
protein correlates with a highly malignant phenotype and a poor prognosis. However, its role in lung cancer still remains unknown. Since
CBX7
is drastically downregulated in human lung carcinomas, we investigated whether restoration of
CBX7
expression could affect growth property of lung cancer cells and modulate their sensitivity to treatment with irinotecan and etoposide, two chemoterapy drugs most commonly used in lung cancer therapy. Here, we demonstrate that restoration of
CBX7
in two human lung carcinoma cell lines (A549 and H1299), in which this protein is not detectable, leads to a decreased proliferation (at least in part through a downregulation of phosphorylated ERK and phosphorylated p38) and an increased apoptotic cell death after drug exposure (at least in part through the downregulation of
Bcl-2
, phosphorylated Akt, and phosphorylated JNK). Taken together, these results suggest that the retention of
CBX7
expression may play a role in the modulation of chemosensitivity of lung cancer patients to the treatment with irinotecan and etoposide.
