Clinical significance of insulin-like growth factor-1 receptor expression in stage I non-small-cell lung cancer: immunohistochemical analysis.

Background/aims: The insulin-like growth factor (IGF) system has been implicated in tumor growth, invasion, and metastasis. However, reports on the IGF-1 receptor (IGF-1R) based on radioimmunoassays are conflicting, and its prognostic implications in non-small-cell lung cancer (NSCLC) are still controversial.

Methods: Seventy-one paraffin-embedded tissue sections from stage I NSCLC patients were stained using a mouse monoclonal antibody against human IGF-1R.

Insulin-like growth factor-1 attenuates cisplatin-induced gammaH2AX formation and DNA double-strand breaks repair pathway in non-small cell lung cancer.

Because insulin-like growth factor-1 (IGF-1) counteracts the anti-neoplastic effect of cisplatin that induces DNA damage and cell death through the formation of platinum-DNA adducts, we investigated the effects of IGF-1 on the DNA double-strand breaks (DSBs) repair system induced by cisplatin. NCI-H1299 and H460 non-small cell lung cancer (NSCLC) cells treated with IGF-1 recovered from cisplatin-derived inhibited proliferation and apoptosis. Decreased tail length in comet assay and suppressed phosphorylation of histone H2AX at Ser139 with IGF-1 cotreatment indicates that IGF-1 attenuates cisplatin-induced DNA damage.

Debilitating stresses do not increase blood-brain barrier permeability: Lack of the involvement of corticosteroids.

The involvement of corticosteroids in stress-induced change in blood-brain barrier (BBB) permeability was investigated. Mice were adrenalectomized and administered with pyridostigmine bromide (PB) or Evan's blue, markers of BBB penetration, followed by 18-h cold-restraint stress (CRS). Rats were administered with mifepristone, a corticosteroid receptor blocker, and the markers, followed by 4-h water immersion-restraint stress (WIRS).
