Objective: To prepare and characterize the polyclonal antibody against KIAA0649 and identify the localization and the functional motif of KIAA0649. Methods: Three polypeptides were synthesized based on the bioinformatics analysis of KIAA0649 protein. New Zealand rabbits were immunized with the mixture of the three KIAA0649 peptides coupled with keyhole limpet hemocyanin ( KLH). The titer of the antisera was detected with ELISA. The antisera were purified with immuno-affinity chromatography when the titer reached 1:10~5. Western blot was performed with the purified antisera on the cell lysates of U2OS cells transfected with either Flag-KIAA0649 or KIAA0649-targeting siRNA. Immunofluorescence was performed with the purified antisera and anti-Flag antibody on the cells transfected with FlagKIAA0649. A series of Flag-K1AA0649 deletion mutants was constructed by PCR cloning. The cellular compartmentation of full-length Flag-KIAA0649 and its deletion mutants were analyzed with immunofluorescence. Results: The results of Western blot and immunofluorescence demonstrated that the antisera from the KIAA0649 polypeptides-immunized rabbits specifically recognized endogenous and exogenous KIAA0649. The full-length Flag-K1AA0649 displayed specific nuclear foci. The Flag-KIAA0649 deletion mutant containing PENF motif showed the same nuclear foci as the full length of Flag-KJAA0649, suggesting that the PENF motif could be the minimum functional motif of KIAA0649. Conclusion: We have obtained anti-KIAA0649 polyclonal antibody which will be useful for further investigation. The PENF motifcould be the minimum functional domain of KIAA0649.

Objective:To analyze the disadvantages of " paper-centric" in science and technology evaluation, explore how to establish a new evaluation model of scientific and technological innovation in academic universities in China on the premise of breaking the " paper-centric" orientation.Methods:Analyze problems and disadvantages of the " paper-centric" orientation in the evaluation of science and technology at academic universities in China, take account into the in-depth interpretation of key policies of breaking away from " paper-centric" in recent years, and finally make proposal for the establishment of evaluation system and mode of scientific and technological innovation in the future.Results:There are many pitfalls in the " paper-centric" orientation in the evaluation of science and technology in academic universities in China, thus, it is urgent to establish a new evaluation mode of scientific and technological innovation.Conclusions:Based on the current domestic and international context, academic universities in China should deploy the strategy of scientific and technological innovation in advance, break the " paper-centric" orientation, and establish a new evaluation system and mode of science and technology that proactively match the national strategy and the development requirement.

Objective:To analyze the intellectual property risk of international cooperative scientific research involving human genetic resources, explore possible risk control measures regarding to intellectual property.Methods:By means of literature review, this paper analyzes the special attributes and strategic position of human genetic resources, reviews the policies and systems involving human genetic resources in international cooperative scientific research, identifies the intellectual property risk points, and puts forward suggestions on risk management and control from the perspective of intellectual property protection.Results:The management of human genetic resources in China is evolving quickly. However, there is still a lack of practical guidelines on intellectual property protection and development, more substantial engagement and contribution of Chinese investigators in the international collaborative research should be promoted, and the perception and awareness of the significance of human genetic resources should be enhanced.Conclusions:In the international cooperative scientific research involving human genetic resources, we should clarify the operating rules at the level of intellectual property protection, improve the substantive participation of Chinese investigators, enhance the strategic awareness and risk awareness of human genetic resources, and provide support at the level of executive management institutions.
