Objective·To establish various in vitro screening systems for the discovery of peptide inhibitors targeting the interaction between small ubiquitin-like modifier(SUMO)-activating enzyme subunit 1(SAE1)and subunit 2(SAE2),as well as to evaluate their advantages,disadvantages,and applicability to this research.Methods·The DNA fragments encoding human SAE1 and SAE2 were cloned into vector pET-28a,respectively,to generate protein SAE1 and SAE2.Purified proteins were used to establish screening assays,including isothermal calorimetry(ITC),fluorescence polarization(FP),surface plasmon resonance(SPR)and a fluorescence assay based on the SAE enzyme activity.The inhibitory activity of peptide candidates in different screening systems was examined,and their performance in terms of sensitivity,robustness,throughput and cost was evaluated.Results·The dissociation constant(Kd)of in vitro SAE1 and SAE2 interaction was determined to be 0.96 μmol/L by ITC,and PEPT7 was identified as the most potent peptide.However,the tracer of FP,which was derived from PEPT7,was not up to snuff due to its low affinity with SAE2.In the SPR assay,the Kd value(=1.13 μmol/L)of SAE1 and SAE2 interaction was in line with the results from ITC.The SAE enzyme activity-based screening assay revealed that HP1B,the most effective peptide,inhibited SAE with an half-maximal inhibitory concentration(IC50)of 15.72 μmol/L.The affinity of HP1B for SAE1 was determined to be 34.4 μmol/L by SPR.Conclusion·Several common screening systems for protein-protein interation(PPI)inhibitors are established and compared.Among them,ITC does not allow for high-throughput screening and it is difficult to accurately evaluate the low-affinity polypeptides with insignificant binding heat.The feasibility of FP relies heavily on the strong affinity between a tracer peptide and the protein target,making it unsuitable for the screening and optimization of low-affinity peptides.SPR is highly sensitive but the cost is high.The SAE enzyme activity-based assay stands out because it is a combination of high sensitivity,robustness,throughput and acceptable cost.

Objective To analyze the postoperative effect of probiotics combined with Peitu Shengjin moxibustion and cupping on adenomatous colorectal polyps (ACP).Methods Patients with ACP diagnosed and treated in Zhejiang Provincial Hospital of Traditional Chinese Medicine from August 2021 to May 2022 were recruited as study subjects,and were divided into control group(probiotics) and test group (probiotics combined with Peitu Shengjin moxibustion and cupping).The main outcome measure of this study was the 1-year recurrence rate of ACP.The secondary outcome measures were the treatment efficiency and the traditional Chinese medicine (TCM) syndrome scores at 4 weeks and 1 year after ACP surgery.Results The study finally included 199 patients,with 100 in the control group and 99 in the test group.The 1-year postoperative treatment efficiency of the test group was higher than that of the control group (P=0.012);the recurrence rate was lower than that of the control group (P<0.05).There was no statistically significant difference in the comparison of polyp size and number between the two groups of patients with recurrence (P>0.05).Before treatment,there was no statistically significant difference between the two groups in the comparison of stool habit score,stool nature score,blood in stool score,stool frequency score,abdominal pain score and total score (P>0.05).The stool habit score,stool nature score,stool blood score,stool frequency score,abdominal pain score and total score of the patients in both groups were significantly lower than those of the preoperative period at 4 weeks and 1 year after the operation (P<0.05).Stool habit score,stool nature score,stool blood score,stool frequency score,abdominal pain score and total score were lower in the test group than in the control group at 4 weeks and 1 year postoperatively (P<0.05).Conclusion Probiotics combined with Peitu Shengjin moxibustion and cupping can effectively improve the TCM syndrome scores after ACP surgery and reduce the recurrence rate of ACP.
