采用SMART技术和RT-PCR方法，从同一个银环蛇毒腺中克隆到了5 种尚未报道过的心脏毒素类似物全长cDNA序列（MNCTL1-a、MNCTL1-b、MNCTL1-c、MNCTL1-d和MNCTL2）。5种序列中，MNCTL1-b、MNCTL1-c、MNCTL1-d和MNCTL2的长度均为505 bp，包括5′非翻译区32 bp，3′非翻译区212 bp和其余261 bp组成的一个完整开放阅读框；MNCTL1-a 由于3′非翻译区24 bp的缺失，全长cDNA仅为481 bp。

Results (1) The forward and reverse subtracted cDNA libraries of different metastastic potential large cell lung cancer cell lines were successfully constructed;(2) With blue-white colony and dot blot, 307 positive clones in the forward subtracted library and 78 positive clones in the reverse subtracted library were obtained;(3) 55 clones were successfully sequenced in the forward subtracted library. Homolog analysis confirmed 23 differential expression segments, which were similar to the human genes already known, including NME2, NPM1, MT 2A, HSPE1, TAFIA, EPRS, PX19 and EIF3S9 et al;(4) 31 clones were successfully sequenced in the reverse subtracted library. Homolog analysis confirmed 16 differentially expressed segments. 15 of them were similar to the human genes already known, including ANXA2, TUBB, PKN2, GNAS, EEF1A1, SSR2 and RPLPO et al. Only one segment had partial homology to known human genes. This segment was supposed to be the new EST segments which might not have been cloned.

Six different deletion and insertion mutants of BBSV-X were constructed and these were inoculated to Chenopodium amaranticolor. The preliminary results show that the sat-RNA could enhance symptom of BBSV-X and its insertion mutants on Chenopodium amaranticolor, but the pathogenicity of the CP deletion mutants was reduced.

Nucleoprotein is also a major immunogenetic antigen for SARS; however, several tests have shown that N protein had the reactivity with other coronavirus positive sera. It is therefore an advantage of S protein as recombinant target antigen for SARS serum diagnosis compared with recombinant N protein. Moreover, S protein has been shown to be the major antigenic determinant that induces neutralizing antibodies and protective immunity to SARS-CoV, so it is also important in designing SARS genetic engineering vaccine.

SARS-CoV S 蛋白由1255 个氨基酸组成，体外表达如此大的蛋白很困难，而且表达蛋白的可溶性不高；其次，实验已经证实，全长S 蛋白含有大量无关的表位，致使表达的全长S蛋白对SARS 阳性血清的检出率低于S 蛋白片段；另外作为疫苗研究，S 蛋白上大量无关表位作为异体蛋白进入体内，会引发机体的过度免疫反应，这也是SARS-CoV 可能的致病机理之一。
