To investigate the circuit-level neural mechanisms of behavior, simultaneous imaging of neuronal activity in multiple cortical and subcortical regions is highly desired. Miniature head-mounted microscopes offer the capability of calcium imaging in freely behaving animals. However, implanting multiple microscopes on a mouse brain remains challenging due to space constraints and the cumbersome weight of the ***, we present TINIscope, a Tightly Integrated Neuronal Imaging microscope optimized for electronic and opto-mechanical design. With its compact and lightweight design of 0.43 g, TINIscope enables unprecedented simultaneous imaging of behavior-relevant activity in up to four brain regions in ***-of-concept experiments with TINIscope recorded over 1000 neurons in four hippocampal subregions and revealed concurrent activity patterns spanning across these regions. Moreover, we explored potential multi-modal experimental designs by integrating additional modules for optogenetics, electrical stimulation or local field potential recordings. Overall, TINIscope represents a timely and indispensable tool for studying the brain-wide interregional coordination that underlies unrestrained behaviors.

N6-methyladenosine facilitates mitochondrial fusion of colorectal cancer cells via induction of GSH synthesis and stabilization of OPA1 mRNA

引用

National Science Review 2024年第3期11卷 72-91页

作者： Jiawang Zhou Haisheng Zhang ke Zhong Lijun Tao Yu Lin Guoyou Xie Yonghuang Tan You Wu Yunqing Lu Zhuojia Chen Jiexin Li Xin Deng Qin Peng Zigang Li Hongsheng Wang Guangdong Provincial key Laboratory of New Drug Design and Evaluation School of Pharmaceutical Sciences Sun Yat-sen University Sun Yat-sen University Cancer Center State Key Laboratory of Oncology in South China and Collaborative Innovation Center for Cancer Medicine Department of biomedical Sciences City University of Hong Kong Institute of Systems and Physical biology Shenzhen Bay Laboratory

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.

Unraveling the evolution of oxygen vacancies in TiO/Cu and its role in COhydrogenation

引用

作者： ke Wang Fanxing Zhang Ning Cao Ying bao Mi Yan ke.ing Yan Pengfei Xie State key Laboratory of baiyunobo Rare Earth Resource Researches and Comprehensive Utilization Baotou Research Institute of Rare Earths School of Materials Science and Engineering Zhejiang University Institute of Zhejiang University-Quzhou College of Chemical and biological Engineering Zhejiang University Department of Chemistry Western Washington University Shanxi-Zheda Institute of Advanced Materials and Chemical Engineering

The remarkable contribution of oxygen vacancies has been revealed by the operando spectroscopies for methanol synthesis from CO2hydrogeneration on the reducible metal oxide-supported copper catalysts. However, a challenge remains in the intrinsic understanding of the evolution and advantage of oxygen vacancies for methanol synthesis. Here we prepare the TiO2–x/Cu with different oxygen vacancy densities by adjusting the ball-milling frequency. At the optimal condition, a TiO2–x/Cu with more oxygen vacancies delivers an excellent methanol yield of 26.5 mmol g-1h-1at 300 °C with a selectivity of more than 70%. The combined analysis of experimental characterizations and theoretical calculations reveals that the mutual dispersions of TiO2–xand Cu driven by mechanical energy induce the electron rearrangement in the d orbital of the Ti atom and relax the Ti–O binding at the interface, which facilitates the formation of oxygen vacancies that further reduce the barrier of CO2hydrogenation to*HCOO due to higher nucleophilicity of titanium ions.
