Proteolytic cleavage is one of the post-translational modifications and plays important roles in many biological processes, such as apoptosis and tumor cell metastasis. The identification of the cleavage events can improve our understanding of their biological functions in these processes. Although proteomic approaches using N-terminal labeling have resulted in the discovery of many proteolytic cleavages, this strategy has its own inherent drawbacks. Labeling of protein C-termini is an alternative approach. Here, we optimized the labeling procedure in the profiling protein C-termini by enzymatic labeling (ProC-TEL) and improved the labeling efficiency for the positive isolation of protein C-terminal peptides and mass spectrometric identification. We applied this approach to a complex protein mixture from Escherichia coli and identified many C-terminal peptides and internal cleaved peptides from more than 120 proteins. From the identified cleavages, we found several previously known internal proteolytic cleavage sites and many novel ones which may play roles in regulating normal biological processes. This work provides a potential new way, complementary to the N-terminomics, for the identification of proteolytic cleavages in complex biological systems.

Objective To analysis the victim's help-seeking behavior of domestic violence. Methods Using a multi-stage sampling strategy,306 victims of domestic violence were randomly selected and face-to-face interviewed. A self-designed help-seeking questionnaire of domestic violence was administered. Results 33.7%victims felt nowhere to seek help. The three leading helpers they seek were the other family member (34.6%),neighbor and friend( 17.0% ) and community office ( 12.5% ) ,and the community office had highest prevalence of effect (71. 1% ). The prevalence of seeking help from other family member and Women's Federation were highest in urban victims (P＜0.01) ,and seeking help from community office was highest in rural victims (P＜0.01). The three leading helpers were other family member (27.3%) ,community office ( 15.8% ) and neighbor and friend ( 10.9% ) by male victims, and other family member ( 38.0% ), neighbor and friend ( 20.0% ) and community office ( 10.8% ) by female victims. The prevalence of seeking help from neighbor and friend was higher in female than in male ( 20.0% vs 10.9%, x2 = 3. 980, P＜ 0.05 ). Adult victims seek help from other family member were less than children and the elderly (31.6% vs 42.0% and 46.9%, x2 =5.993, P＜0.05),and the elderly seek help from community office were more than adults and children (28.1% vs 12. 1% and 4.0%, x2 =9.930, P＜0.01 ). The victims with higher level of education were with higher prevalence of feeling nowhere to seek help (47.8%). Seeking help from other family member and community office were most in victims with lower level of education( 38.5% and 24.0% ,respectively) and were least in victims with higher level of education ( 17.4% and 0,respectively, P ＜ 0.05, P ＜ 0. 01 ). Conclusion Help-seeking behaviors of victims of domestic violence are varied by geographic settings,age,gender and education levels.

Objective In previous study,we carried out refined mapping of loss of heterzygosity (LOH) on 1q31.1-32.1 and found that a minimal region of frequent deletion was located at DIS413-D1S2622,which indicated that the region could harbor a tumor suppressor gene associated with colorectal carcinoma.This study was to screen for the potential tumor suppressor gene (TSG) on D1S413-D1S2622 in Chinese origin patients with sporadic colorectal cancer.Methods 25 genes located in the D1S413-D1S2622 region were chosen and a microarray-based high throughput screening conducted in 19 sporadic colorectal cancers to identify candidate tumor suppressor genes.The relationship between expression levels of candidate genes and the clinicopathological data was analyzed.Real-time PCR was performed to validate the microarray results.Results According to the microarray-based high throughput screening,we found 4 significantly down-expressed genes,including CSRP1,LMOD1,PPP1R12B and CFHL3.There was no significant association between of CFHL3,CSRP1,LMOD1,PPP1R12B expression and the clinicopathological data.CSRP1 could be a colorectal cancer related tumor suppressor gene.CSRP1 was down-regulated in colorectal cancer.Conclusions CSRP1 might be involved in the progression of colorectal cancer.
