Purpose: Triple-negative breast cancer (TNBC), the most aggressive subtype of breast cancer, is associated with high invasiveness, high metastatic occurrence and poor prognosis. Protein tyrosine kinase 7 (PTK7) plays an important role in multiple cancers. However, the role of PTK7 in TNBC has not been well addressed.

Background: Epidermal growth factor receptor (EGFR), c-Met, and human epidermal growth factor receptor 2 (HER2) are overexpressed in a variety of human cancers, and may serve as biomarkers for disease prognosis. We examined whether high expression of these molecular markers correlates with poor disease prognosis in esophageal squamous cell cancer (ESCC).

Materials And Methods: Expression of EGFR, c-Met, and HER2 protein was detected by immunohistochemistry (IHC) in 180 paraffin-embedded tissue samples from stage IIB-IIIC ESCC patients.

Objective: It is still unclear whether the clinicopathological and outcome characteristics of vascular invasion (VI) (+) papillary thyroid carcinoma (PTC) differ from VI (-) PTC. This study aims to establish distinguishing features of patients with VI (+) and VI (-) PTC and to investigate the biological and clinical aggressiveness of the disease in these patient groups.

Design: A matched-case comparative study.

Human epidermal growth factor receptor 2 (HER2/neu or HER2) has long been recognized as an attractive therapeutic target for breast cancer. The YVMA in-frame insertion at the residue G776 (G776(YVMA)) of HER2 kinase domain is a frequently observed mutation that can largely shift drug sensitivity in targeted therapy of HER2-positive breast cancer. Here, the molecular mechanism and biological significance of tyrosine kinase inhibitor (TKI) response to HER2 G776(YVMA) insertion were investigated in detail.

Esophageal squamous cell carcinoma (ESCC) is the eighth most frequent neoplasm in China. However, the expression levels of human epidermal growth factor receptor 2 (HER2) and multidrug resistance protein 1 (MRP1) in patients with ESCC remain to be determined. In the present study, 829 ESCC cases were evaluated using immunohistochemistry.

Alterations of the epidermal growth factor receptor (EGFR), including overexpression or gene mutations, contribute to the malignant transformation of human epithelial cells. The aim of this study was to assess EGFR overexpression or gene amplification in esophageal squamous cell carcinoma (ESCC) tissue samples and investigate their correlations with biological behaviors. Tissue specimens from 56 patients with surgically resected ESCC were obtained for immunohistochemical analysis of EGFR expression and fluorescence hybridization analysis of amplification.

ATM and γH2AX play a vital role in the detection of DNA double-strand breaks (DSB) and DNA damage response (DDR). This study aims to investigate ATM and γH2AX expression in thyroid cancer and discuss possible relationship between thyroid function tests and DNA damage. The expression of ATM and γH2AX was detected by immunohistochemistry in 30 cases of benign nodular goiter, 110 cases of well differentiated thyroid cancer, 22 cases of poorly differentiated thyroid cancer, and 21 cases of anaplastic thyroid cancer.

Using the whole-cell patch-clamp technique, delayed outward currents were recorded in rat brain microvascular endothelial cells(RBMECs), which were nearly completely inhibited by extracellular TEA-Cl at a concentration of 20 mmol/L. Whole-cell currents were elicited by 2 100 ms depolarizing voltage pulses applied every 7 s between -100 mV to +90 mV, with 10 mV increment, from a holding potential of -100 mV. The currents were similar with delayed rectified K(+) currents (IKv)which were inhibited in a concentration-dependent manner by both application of TEA-Cl, with an IC(50) approximately 2.
