Abstract:
Objective To test different expression protein markers of the serum from B-cell non-Hodgkin lymphoma(B-cell NHL) between diffuse large B-cell lymphoma(DLBCL) and follicular lymphoma(FL)patients using sudace enhanced laser desorption/ionization-time of flight-mass spectrometry(SELDI-TOF-MS)protein chip technology. Further, to test different expression of the protein markers of B-eell NHL patients after chemical therapy in order to discuss clinical significance. Methods Different expression of protein markers were analysed in serum between 54 B-cell NHL patients and 27 healthy volunteers by using SELDI-TOF-MS WCX-2 pertein chip. Meanwhile different expression of protein markers relative to pathology classification between 23 DLBCL patients and 12 FL patients were screened; and protein markers which affected prognosis of 23 DLBCL patients were screened. Results There were five specific marker proteins in 54 B-cell NHL patients and 27 healthy volunteers. Their relative molecular weights were 7974, 15 938, 3398,8564, and 8692. The protein markers of 7974 and 15 938 were at high level in patients and the protein markers of 3398, 8564 and 8692 were at low level in patients. There were two protein markers which affected the prognosis, with better outcome when the expression of 4795 and 4998 were increased. Conclusion SELDI-TOF-MS protein chip technology is a quick, easy and convenient method, with high-throughput analyzer which can screen several relatively specific protein markers from the serum of patients to diagnose B-cell NHL The relatively specific protein markers can be used to make pathology classification and to judge the prognosis of B-cell NHL, and have better clinical value.
