Mandatory and restrictive health regulations during the corona pandemic caused psychic disorders in many people,which even led to clinically relevant mental disorders.At the same time,there was gradually a polarization of opinions among the population.In order to improve future pandemic management,an integrative understanding of these psychosocial processes therefore seems useful.Here we start theoretically with the mental effects of inconsistencies of the information environment by referring to concepts such as the theory of cognitive dissonance.In a next step,we use the psychodynamic theory to understand the affective-motivational defense mechanisms underlying these cognitive states and processes.However,a broader theoretical framework of psychoanalysis seems to make sense,because self-referential processing also influences the style of thinking.For this reason,we use a more comprehensive psychological systems theoretical framework model to integrate these different perspectives.This integrative view refers in part to basic knowledge of health psychology regarding the resistance of unhealthy ways of thinking and behaviors and the possibilities for interventions for change.We then extend this model to a broader picture that also covers the relationship between men and their environment.This results in the perspective of a multidimensional socioecological theoretical framework,which as a heuristic reference model and related to other ecological approaches could also be helpful for various theoretical questions for public health,and could provide a better public understanding of health issues.In line with this perspective,we hypothesize that with regard to the coronavirus disease 2019 pandemic,the acceptance of public health narratives could be increased if a more consistent picture of the scientific descriptions and explanations of the pandemic-similar to the model proposed-could be provided,which would enable the understanding of the origin,course and countermeasures,and thus could have positive collective psych

Science China(Information Sciences) 2024年第6期67卷 445-447页

作者： Long WANG Feng FU Xingru CHEN center for systems and Control College of EngineeringPeking University center for Multi-Agent Research Institute for Artificial IntelligencePeking University Department of Mathematics Dartmouth College Department of Biomedical Data Science Geisel School of Medicine at Dartmouth School of Science Beijing University of Posts and Telecommunications

Evolutionary game theory (EGT) and artificial intelligence(AI) are two fields that,at first glance,might seem distinct,but they have notable connections and intersections.The former focuses on the evolution of behaviors (or strategies)in a population,where individuals interact with others and update their strategies based on imitation (or social learning).

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

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

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.

Phosphatase and tensin homolog(PTEN)is a multifunctional gene involved in a variety of physiological and pathological processes.Circular RNAs(circRNAs)are generated from back-splicing events during mRNA processing and participate in cell biological processes through binding to RNAs or proteins.However,PTEN-related circRNAs are largely unknown.Here,we report that circPTEN-mitochondria(MT)(hsa_circ_0002934)is a circular RNA encoded by exons 3,4,and 5 of PTEN and is a critical regulator of mitochondrial energy metabolism.CircPTEN-MT is localized to mitochondria and physically associated with leucine-rich pentatricopeptide repeat-containing protein(LRPPRC),which regulates posttranscriptional gene expression in mitochondria.Knocking down circPTEN-MT reduces the interaction of LRPPRC and steroid receptor RNA activator(SRA)stem-loop interacting RNA binding protein(SLIRP)and inhibits the polyadenylation of mitochondrial mRNA,which decreases the mRNA level of the mitochondrial complex I subunit and reduces mitochondrial membrane potential and adenosine triphosphate production.Our data demonstrate that circPTEN-MT is an important regulator of cellular energy metabolism.This study expands our understanding of the role of PTEN,which produces both linear and circular RNAs with different and independent functions.

The limited infiltration and persistence of chimeric antigen receptor(CAR)-T cells is primarily responsible for their treatment deficits in solid tumors. Here, we present a three-dimensional scaffold, inspired by the physiological process of T-cell proliferation in lymph nodes. This scaffold gathers the function of loading,delivery, activation and expansion for CAR-T cells to enhance their therapeutic effects on solid tumors. This porous device is made from poly(lactic-co-glycolic acid) by a microfluidic technique with the modification of T-cell stimulatory signals, including anti-CD3, anti-CD28 antibodies, as well as cytokines. This scaffold fosters a 50-fold CAR-T cell expansion in vitro and a 15-fold cell expansion in vivo. Particularly, it maintains long-lasting expansion of CAR-T cells for up to 30 days in a cervical tumor model and significantly inhibits the tumor growth. This biomimetic delivery strategy provides a versatile platform of cell delivery and activation for CAR-T cells in treating solid tumors.

Signal Transduction and Targeted Therapy 2024年第1期9卷 10-11页

作者： Anna Brichkina Roman Suezov Magdalena Huber Institute of systems Immunology Member of the German Center for Lung Research(DZL)Philipps University of Marburg35043 MarburgGermany

In a recent article published in Cancer Discovery,Guirguis et al.demonstrated that enzymatic inhibitors of the m6 A methyltransferase METTL3 induced a formation of immunostimulatory doublestranded mRNAs(dsRNAs)in cancer cells,which triggered a profound tumor-cell-intrinsic interferon response leading to an enhanced antigen presentation and thereby increased killing of tumor cells by cytotoxic CD8+T-lymphocytes.The inhibition of METTL3 synergized with anti-PD1 immunotherapy,highlighting its potential for improving cancer treatment.
