In recent years, as the infectious diseases caused by pathogens such as novel coronavirus and mpox (formerly called monkeypox) spread globally, the significance of identification, preservation, and sharing of pathogenic resources become prominent. Along with the rapid development of biorepositories, it is imperative to evaluate their operation in a scientific manner. By using the literature review and modified Delphi method, this study develops a benchmarking tool for the comprehensive evaluation of the operation of biorepositories for pathogenic resources. The effective response rates of both rounds of expert surveys were 100 %. The authority coefficients (Cr) were 0.82 and 0.85, respectively, manifesting the reliability of consultation results. In the second-round survey, the Kendall’s coefficient of concordance (Kendall’s W) of all indicators ranged from 0.09 to 0.31 (P < 0.001), the comprehensive score ranged from 4.02 to 4.94, the standard deviation ranged from 0.21 to 0.77, and the coefficient of variation (CV) ranged from 0.04 to 0.22, indicating that the expert opinions reached consensus. The final benchmarking tool was composed of 4 primary indicators, 12 secondary indicators, and 65 tertiary indicators. The weights of the four primary indicators allocated through the ranksum ratio method, namely organizational structure, management requirements, biobanking capacity, and sharing capacity, were 30.50 %, 30.08 %, 25.45 %, and 13.97 %, respectively. The benchmarking tool established in this study provides references for the comprehensive evaluation of the operation and puts forward advice for the sustainable development of biorepositories for pathogenic resources.

Mitochondria undergo fission and fusion that are critical for cell survival and cancer development, while the regulatory factors for mitochondrial dynamics remain elusive. Herein we found that RNA m6A accelerated mitochondria fusion of colorectal cancer（CRC） cells. Metabolomics analysis and function studies indicated that m6A triggered the generation of glutathione（GSH） via the upregulation of RRM2B——a p53-inducible ribonucleotide reductase subunit with anti-reactive oxygen species potential. This in turn resulted in the mitochondria fusion of CRC cells. Mechanistically, m6A methylation of A1240 at 3 UTR of RRM2B increased its m RNA stability via binding with IGF2BP2. Similarly, m6A methylation of A2212 at the coding sequence（CDS） of OPA1——an essential GTPase protein for mitochondrial inner membrane fusion——also increased m RNA stability and triggered mitochondria fusion. Targeting m6A through the methyltransferase inhibitor STM2457 or the dm6ACRISPR system significantly suppressed mitochondria fusion. In vivo and clinical data confirmed the positive roles of the m6A/mitochondrial dynamics in tumor growth and CRC progression. Collectively, m6A promoted mitochondria fusion via induction of GSH synthesis and OPA1 expression, which facilitated cancer cell growth and CRC development.
