Identification of SEC61β and its autoantibody as biomarkers for colorectal cancer.

Background: To identify novel serological biomarkers for human colorectal cancer (CRC), we analyzed CRC tissues using gel-assisted digestion and isobaric tags with related and absolute quantitation (iTRAQ) labeling mass spectrometry (MS). By comparing pairs of tumor tissues and matched normal tissues, we discovered the SEC61β with expression changes 3.3-fold and a marginal statistical significance (p=0.

Luminescent silver metal chains with unusual mu4-bonded 2,2'-bipyrazine.

An unusual mu4-bridging bonding mode of 2,2'-bipyrazine is observed for the first time in a luminescent coordination polymer [Ag2(bpyz)(NO3)2]n, which comprises of silver chains with alternating strong and weak Ag...
