AIM: To investigate whether focal adhesion kinase (FAK) takes part in the intracellular signaling pathway involved in apoptosis of human pulmonary artery smooth muscle cells (HPASMCs). METHODS: Cultured HPASMCs stimulated by fibronection (40 mg/L) were passively transfected with antisense-FAK oligodeoxynucleotides (ODNs). Expression of FAK and caspase-3 proteins was detected by immunoprecipitation and Western blotting. In addition, apoptosis were measured by TUNEL. RESULTS: The protein expression of FAK in HPASMCs decreased and caspase-3 expression upregulated in HPASMCs in antisense-FAK ODNs group. At the same time, antisense-FAK ODNs transfection increased the rate of cell apoptosis. CONCLUSION: These results suggest that FAK may be related with the apoptosis of HPASMCs. Antisense-FAK ODNs inhibit HPASMC proliferation and may facilitate their apoptosis via caspase-3 signaling pathway.

Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is a kind of targeted drug for the treatment of non-small cell lung cancer (NSCLC),but almost all patients develop EGFR-TKI resistance.In Chinese medicine,it is believed that Yang deficiency is the leading cause of tumor,which could end up with the internal formation of cancer toxin and promote the formation of tangible excess pathogens.Clinical and experimental studies have shown that the Chinese medicine treatment based on Yang-warming method can inhibit EGFR-TKI resistance and improve the therapeutic effect of EGFR-TKI.The mechanism may be related to the regulation of miRNA gene and estrogen receptor expression,being against tumor heterogeneity and the regulation of tumor microenvironment.Therefore,Yang deficiency is the key pathogenesis of the EGFR-TKI resistance in NSCLC,and the method reinforcing Yang and suppressing Yin is the basic therapeutic way in Chinese medicine to overcome EGFR-TKI resistance.

To investigate the effect of cigarette smoke extract (CSE) on the role of protein kinase C (PKC) in the proliferation of passively sensitized human airway smooth muscle cells (HASMCs). After synchronization of cultured HASMCs, they were divided into a group A and Group B. The group A was treated with normal human serum and served as controls and the group B was treated with the serum of asthma patients. The group A was further divided into group of A1, A2 and A3 and the group B was sub-divided into the group of B1, B2, B3, B4 and B5. No other agents were added to the group A1 and B1. The cells of group A2 and B2 were stimulated with 5% CSE for 24 h. HASMCs from group A3 and B3 were treated with PKC agonist PMA (10 nmol/L) and CSE (5%) for 24 h. PKC inhibitor Ro-31-8220 (5 micromol/L) was added to the HASMCs of group B4 for 24 h. The cells from group B5 were stimulated with Ro-31-8220 (5 micromol/L) and CSE (5 %) for 24 h. The proliferation of HASMCs isolated from group A and B was examined by cell cycle analysis, MTT colorimetric assay and 3H-TdR incorporation test. The expression of PKC-a in each group was observed by Western blotting and RT-PCR, respectively. The results showed that the percentage of S phase, absorbance (A) value, the rate of 3H-TdR incorporation, the ratios of A value of PKC-alpha mRNA and the A value of PKC-alpha protein in HASMCs from group B1, B2 and B3 were significantly increased compared to those of group A1, A2 and A3 correspondingly and respectively (P< 0.01). The proliferation of HASMCs of group A2 and B2 stimulated with CSE and group A3 and B3 stimulated with CSE and PMA were also significantly enhanced when group A1, A2 and A3 and group B1, B2 and B3 compared to each other (P<0.05, P<0.01, respectively). The percentage of S phase, absorbency (A) value, 3H-TdR incorporation rate, the ratios of A value of PKC-alpha mRNA and the A value of PKC-alpha protein in HASMCs from group B4 treated with Ro-31-8220 and group B5 treated with CSE and Ro-31-8220 were significantly decreased as compared to those of group B1 and B2 correspondingly and respectively (P<0.05, P<0.01). It was concluded that CSE can enhance the passively sensitized HASMC proliferation and the expression of PKC alpha. PKC and its alpha subtype may contribute to this process. Our results suggest cigarette may play an important role in ASMCs proliferation of asthma through PKC signal pathway.
