The corona-like spikes or peplomers on the surface of the virion under electronic microscope are the most striking features of coronaviruses. The S (spike) protein is the largest structural protein, with 1,255 amino acids, in the viral genome. Its structure can be divided into three regions: a long N-terminal region in the exterior, a characteristic transmembrane (TM) region, and a short C-terminus in the interior of a virion. We detected fifteen substitutions of nucleotides by comparisons with the seventeen published SARS-CoV genome sequences, eight (53.3%) of which are non-synonymous mutations leading to amino acid alternations with predicted physiochemical changes. The possible antigenic determinants of the S protein are predicted, and the result is confirmed by ELISA (enzyme-linked immunosorbent assay) with synthesized peptides. Another profound finding is that three disulfide bonds are defined at the C-terminus with the N-terminus of the E (envelope) protein, based on the typical sequence and positions, thus establishing the structural connection with these two important structural proteins, if confirmed. Phylogenetic analysis reveals several conserved regions that might be potent drug targets.

Objective To investigate the distribution of human papillomavirus ( HPV ) in the diseased areas cut from HPV?positive cervical adenocarcinoma ( ADC ) detected by laser capture microdissection ( LCM ) . Methods Paraffin?embedded specimens diagnosed as ADC between 2005 and 2010 were collected from 9 hospitals in 7 regions across China. HPV genotyping was conducted on paraffin sections using sandwich technique and LCM in order to identify HPV infection in the tumor tissues. HE and p16 immunohistochemistry staining were performed to make histological diagnosis. Results A total of 169 cervical adenocarcinoma cases were recruited, including 94 cases of mucinous adenocarcinoma ( ADC?CX) , 9 cases of adenosquamous carcinoma ( ASC) , 19 cases of minimal deviation adenocarcinoma ( ADC?MIN) , 14 cases of clear cell adenocarcinoma ( ADC?CC) , 8 cases of endometrioid adenocarcinoma ( ADC?ENDO) , 9 cases of serous adenocarcinoma ( ADC?SER ) and 16 cases of adenocarcinoma not otherwise specified (ADC?NOS). Fourteen types of high risk HPV were detected in the whole tissue section (WTS). HPV16 was the most common type, and the second was HPV18 and HPV52, respectively. Compared with WTS, the HPV?positive rate detected by LCM was lower. The HPV positive rates were significantly different among different subtypes of cervical adenocarcinoma ( P<0.001) . After LCM, the HPV positive rate was 50.8% and 66.7% in the single infection and multiple, infection groups respectively (P=0.14). The positive rates of p16 was significantly different among different subtypes of cervical adenocarcinoma ( P<0.001) . p16?positive rate was 73. 9% in the HPV?positive samples after LCM, significantly higher than the 38. 5% of negative samples ( P<0.001) . Conclusions Laser capture dissection technique can more precisely reflect the HPV distribution in cervical adenocarcinomas. The etiological association between HPV infection and cervical adenocarcinoma occurrence is not as close as that reported in the literature.
