When properly labeled 99mTc-RBCs are injected into a patient, these labeled cells are fairly stable in the circulation thus allowing scintigraphic studies on cardiovascular system. Among various modified techniques published for 99mTc-RBCs labeling, incubation of RBCs with 99mTc pertechnetate then with tin yielded 99mTc-RBCs most stable in the circulation. Average labeling efficiency of 99mTc-RBCs was 66%. After an injection of about 10 mCi 99mTc-RBCs, clear images of the heart chambers and major vessels could be obtained using a gamma camera. Resolution of vascular structures improved significantly when images were taken using gamma camera equipped with pinhole collimator. Radionuclide angiography with 99mTc-RBCs was very useful in detection of abdominal aortic aneurysm, evaluation of mediastinal mass--thoracic aortic aneurysm, and detection of abnormality in a smaller vessel such as carotid artery. Advantages of this procedure are (1) the technique is simple and noninvasive; (2) it has capability of functional evaluation by obtaining flow study; and (3) multiple and repetitive static views can be obtained even several hours after an injection.

ATPase family AAA domain-containing 2 (ATAD2) has been identified as a critical modulator involved in cell proliferation and invasion. The purpose of this study was to explore the expression of ATAD2 in CRC tissues as well as its relationship with degree of malignancy. Data containing three independent investigations from Oncomine database demonstrated that ATAD2 is overexpressed in CRC compared with normal tissue, and similar result was also found in 32 pairs of CRC tissues by qPCR. The protein expression of ATAD2 was examined in six CRC cell lines and 300 CRC specimens. The results showed that high expression of ATAD2 was significantly correlated with tumor size (P < 0.001), serum CEA (P = 0.012), lymph node metastasis (P = 0.018), liver metastasis (P = 0.025), and clinical stage (P = 0.004). Kaplan-Meier method suggested that higher ATAD2 protein expression significantly associated with the overall survival (OS) of CRC patients (P < 0.001) and was an independent predictor of poor OS. Functional studies showed that suppression of ATAD2 expression with siRNA could significantly inhibit the growth in SW480 and HCT116 cells. These results indicated that ATAD2 could serve as a prognostic marker and a therapeutic target for CRC.
