| 1 | The genetic equidistance result:misreading by the molecular clock and neutral theory and reinterpretation nearly half of a century later显示文摘In 1963,Margoliash discovered the unexpected genetic equidistance result after comparing cytochrome c sequences from different species.This finding,together with the hemoglobin analyses of Zuckerkandl and Pauling in 1962,directly inspired the ad hoc molecular clock hypothesis.Unfortunately,however,many biologists have since mistakenly viewed the molecular clock as a genuine reality,which in turn inspired Kimura,King,and Jukes to propose the neutral theory of molecular evolution.Many years of studies have found numerous contradictions to the theory,and few today believe in a universal constant clock.What is being neglected,however,is that the failure of the molecular clock hypothesis has left the original equidistance result an unsolved mystery.In recent years,we fortuitously rediscovered the equidistance result,which remains unknown to nearly all researchers.Incorporating the proven virtues of existing evolutionary theories and introducing the novel concept of maximum genetic diversity,we proposed a more complete hypothesis of evolutionary genetics and reinterpreted the equidistance result and other major evolutionary phenomena.The hypothesis may rewrite molecular phylogeny and population genetics and solve major biomedical problems that challenge the existing framework of evolutionary biology. | HU TaoBo LONG MengPing YUAN DeJian ZHU ZhuBing HUANG YiMin HUANG Shi | 2013 | Science China(Life Sciences)2013，56，3： | 2 |

| 3 | Mechanism and effect of stress granule formation in cancer and its potential roles in breast cancer therapy显示文摘Stress granules are non-membranous cytoplasmic foci induced by various stress conditions.It is a protective strategy used by cells to suppress overall translation during stress.In cancer cells,it was thought that the formation of stress granules could protect them from apoptosis and induces resistance towards anti-cancer drugs or radiation treatment which makes the stress granules a potential target for cancer treatment.However,most of our understanding of stress granules are still in the stage of molecular and cell biology,and a transitional gap for its actual effect on clinical settings remains.In this review,we summarize the mechanism and effect of stress granules formation in cancer and try to illuminate its potential applications in cancer therapy,using breast cancer as an example. | Taobo Hu Wei Hou Enhua Xiao Mengping Long | 2022 | Genes & Diseases2022，9，3： | 1 |
| 4 | Genetic abnormalities assist in pathological diagnosis and EBVpositive cell density impact survival in Chinese angioimmunoblastic T-cell lymphoma patients显示文摘Objective:To explore the application of genetic abnormalities in the diagnosis of angioimmunoblastic T-cell lymphoma(AITL)and the reliable pathological prognostic factors.Methods:This study included 53 AITL cases,which were reviewed for morphological patterns,immunophenotypes,presence of Hodgkin and Reed-Sternberg(HRS)-like cells,and co-occurrence of B cell proliferation.The Epstein-Barr virus(EBV)-positive cells in tissues were counted,and cases were classified into“EBV encoded RNA(EBER)high-density”group if>50/HPF.Targeted exome sequencing was performed.Results:Mutation data can assist AITL diagnosis:1)with considerable HRS-like cells(20 cases):RHOA mutated in 14 cases(IDH2 co-mutated in 3 cases,4 cases with rare RHOA mutation),TET2 was mutated in 5 cases(1 case comutated with DNMT3A),and DNMT3A mutated in 1 case;2)accompanied with B cell lymphoma(7 cases):RHOA mutated in 4 cases(1 case had IDH2 mutation),TET2 mutated in 2 cases and DNMT3A mutated in 1 case;3)mimic peripheral T cell lymphoma,not otherwise specified(5 cases):RHOA mutated in 2 cases(IDH2 co-mutated in 1 case),TET2 mutated in 3 cases,and DNMT3A mutated in 1 case;4)pattern 1(1 case),RHOA and TET2 co-mutated.Besides RHOAG17V(30/35),rare variant included RHOAK18N,RHOAR68H,RHOAC83Y,RHOAD120G and RHOAG17del,IDH2R172 co-mutated with IDH2M397V in one case.There were recurrent mutations of FAT3,PCLO and PIEZO1 and genes of epigenetic remodeling,T-cell activation,APC and PI3K/AKT pathway.EBER high-density independently indicated adverse overall survival and progression-free survival(P=0.046 and P=0.008,KaplanMeier/log-rank).Conclusions:Over half AITL cases might be confused in diagnosis for certain conditions without mutation data.Targeted exome sequencing with a comprehensive panel is crucial to detect both hot-spot and rare mutation variants for RHOA and IDH2 and other recurrent mutated genes in addition to TET2 and DNMT3A.EBER highdensity independently indicated adverse survival. | Yunfei Shi Haojie Wang Yanfei Liu Mengping Long Ning Ding Lan Mi Yumei Lai Lixin Zhou Xinting Diao Xianghong Li Weiping Liu Jun Zhu | 2023 | Chinese Journal of Cancer Research2023，35，5： | 0 |
