Abstract

This study was aimed to screen the cell cDNA expression library of multiple myeloma HMy2 (MM HMy2) by using "serological analysis of cDNA expression library (SEREX)" technique. The obtained 30 positive clones were all sequenced, and analyzed by BLAST (basic local alignment search tool). The results indicated that 6 known genes and 12 new MM-associated genes were obtained, part of which sequences were spliced by EST (expressed sequence tag) splicing. 6 known genes such as for ring finger protein 167, KLF10, TPT1 protein, p02 protein, cDNA FLJ46859 fis, DNMT1 methyltrasferase etc. have been demonstrated a certain relationship with other tumor's formation, progress and prognosis. The structures and functions of the new genes preliminarily analyzed and predicted by means of bioinformatics showed that MMSA-3, MMSA-8 and MMSA-11 encoding 215, 160 and 122 amino acid residues respectively had the full open reading frames (ORF). All the new genes might be located at euchromosomes but MMSA-1 at sex chromosome. MMSA-4 was highly similar to the protein controlling the transcription of tumor antigen, MMSA-5 might take part in cell phagocytosis, MMSA-7 might inactivated NF-kappaB, and MMSA-12 might be a lymphocytic cytoplasmic protein.
