Recent studies indicate that BTB/POZ domain-containing protein 7 (BTBD7) regulates EMT-associated proteins in human malignancies and however, the role of BTBD7 in lung cancer have not been identified. In present study, we examined BTBD7 expression status and its association with unfavorable clinical features in non-small-cell lung cancer (NSCLC).

Objective: To investigate if the interaction between TGF-beta1/Smad pathway and ERK pathway in vascular smooth muscle cells exists.
Methods: The rat arota was removed. The primary VSMC were isolated and cultured in vitro, then the VSMC were divided into four groups: (1) control group, (2) (TGF-beta1 group, (3) ERK blocking agent group, (4) TGF-beta1 + ERK blocking agent group.
