Upregulated thymic stromal lymphopoietin receptor expression in children with asthma.

Background: Thymic stromal lymphopoietin (TSLP) plays an important role in pathogenesis in patients with asthma. However, the role of thymic stromal lymphopoietin receptor (TSLPR) and correlation with IL-7Rα and clinical severity in asthmatic or nonasthmatic children remain unclear. We investigated TSLPR and IL-7Rα mRΝΑ levels in asthma and nonasthma and assessed TSLPR expression in children who were sensitive to mites.

Decreasing relapse in colorectal cancer patients treated with cetuximab by using the activating KRAS detection chip.

The KRAS oncogene was among the first genetic alterations in colorectal cancer (CRC) to be discovered. Moreover, KRAS somatic mutations might be used for predicting the efficiency of anti-epidermal growth factor receptor therapeutic drugs. Because the KRAS mutations are similar in the primary CRC and/or the CRC metastasis, KRAS mutation testing can be performed on both specimen types.

Detection of activated KRAS from cancer patient peripheral blood using a weighted enzymatic chip array.

Background: The KRAS oncogene was one of the earliest discoveries of genetic alterations in colorectal and lung cancers. Moreover, KRAS somatic mutations might be used for predicting the efficiency of anti-EGFR therapeutic drugs. The purpose of this research was to improve Activating KRAS Detection Chip by using a weighted enzymatic chip array (WEnCA) platform to detect activated KRAS mutations status in the peripheral blood of non-small-cell lung cancer (NSCLC) and colorectal cancer (CRC) patients in Taiwan.
