[Mutation of the BRAF genes in non-small cell lung cancer]

[Progress in the Treatment of Non-small Cell Lung Cancer with BRAF Inhibitors]

In recent years, targeted drugs occupy a pivotal position in the treatment of non-small cell lung cancer (NSCLC), drugs targeting epidermal growth factor receptor (EGFR) has been widely used in clinical practice, it is of milestone significance. V-raf murine sarcoma viral oncogene homolog B1 (BRAF) inhibitors targeted at BRAF gene have obviously clinical efficacy to specific advantages populations with little side-effect, and be well tolerated. It is discovered recently that drug resistance also exists in BRAF inhibitors like other targeted drugs, the mechanism of drug resistance is being studied. In this paper, a review were performed in the mechanism, clinical application, adverse reactions and the drug resistance of BRAF inhibitors.

[Research status on molecular targeted therapy for squamous-cell lung cancer]

Lung cancer is one of the world's highest morbidity and mortality disease in malignant tumors currently. Squamous-cell lung cancer (SQCLC) is one of the most prevalent subtypes of lung cancer worldwide, after surgery, radiotherapy, chemotherapy and other comprehensive treatment, its 5-year survival rate is still below 15%. The current molecular targeted therapy plays an important role in the treatment of SQCLC, an urgent need to be more in-depth study. SQCLC molecular targeted therapy mainly epidermal growth factor receptor (EGFR), phosphoin-3-kinase catalytic alpha polypeptide (PIK3CA), fibroblast growth factor receptor 1 (FGFR1), discoidin domain receptor 2 (DDR2), phosphatase and tensin homolog deleted on chromosome ten (PTEN), BRAF, MET, insulin-like growth factor 1 receptor (IGF-1R) and other as the target of the drug, some targeted drugs are being developed, and some targeted drugs have entered clinical trials. In recent years, with studies molecular targeted therapy in SQCLC, analysis of the development and trgeted therapy achieved substantial progress in improving the survival rate of SQCLC, and other research to improve the quality of life, make is possible to individualized targeted therapy of SQCLC.

Network understanding of herb medicine via rapid identification of ingredient-target interactions

Today, herb medicines have become the major source for discovery of novel agents in countermining diseases. However, many of them are largely under-explored in pharmacology due to the limitation of current experimental approaches. Therefore, we proposed a computational framework in this study for network understanding of herb pharmacology via rapid identification of putative ingredient-target interactions in human structural proteome level. A marketing anti-cancer herb medicine in China, Yadanzi (Brucea javanica), was chosen for mechanistic study. Total 7,119 ingredient-target interactions were identified for thirteen Yadanzi active ingredients. Among them, about 29.5% were estimated to have better binding affinity than their corresponding marketing drug-target interactions. Further Bioinformatics analyses suggest that simultaneous manipulation of multiple proteins in the MAPK signaling pathway and the phosphorylation process of anti-apoptosis may largely answer for Yadanzi against non-small cell lung cancers. In summary, our strategy provides an efficient however economic solution for systematic understanding of herbs' power.
