Amyotrophic lateral sclerosis(ALS)is a progressive neurodegenerative disorder characterized by the degeneration of motor neurons in the brain and spinal cord,leading to muscle weakness,paralysis,and ultimately death(Cleveland and Rothstein,2001).Frontotemporal lobar degeneration(FTLD)is a neurodegenerative disease affecting the frontal and temporal lobes of the brain,leading to changes in behavior,personality,and language(Van Langenhove et al.,2012).Both ALS and FTLD are classified as proteinopathies in which abnormal protein aggregation and accumulation in neurons contribute to the disease *** in sarcoma(FUS)is a DNA/RNA-binding protein involved in various cellular processes,including transcriptional regulation,RNA splicing,and DNA *** in the FUS gene have been linked to familial ALS,highlighting the importance of FUS in the disease pathogenesis(Vance et al.,2009).In ALS and FTLD,aberrant post-translational modifications(PTMs)of FUS,such as phosphorylation,acetylation,and methylation,have been implicated in the promotion of FUS aggregation and neurotoxicity(Choi et al.,2023).Therefore,understanding the regulatory mechanisms of FUS PTMs is crucial for developing targeted therapies against these diseases.

Background Because limited comparative data are available,we decided to compare 2-year major clinical outcomes between beta-blockers (BB) with angiotensin converting enzyme inhibitors (ACEI) and BB with angiotensin receptor blockers (ARB) therapy in patients with non-ST-segment elevation myocardial infarction (NSTEMI) after percutaneous coronary intervention (PCI) with drug-eluting stents (DES).Methods A total 11,288 NSTEMI patients who underwent PCI with DES were enrolled and they were divided into two groups,the BB with ACEI group (n = 7600) and the BB with ARB group (n = 3688).The major clinical endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death,recurrent myocardial infarction (re-MI),total revascularization [target lesion revascularization (TLR),target vessel revascularization (TVR),non-TVR] rate during the 2-year follow-up *** After propensity score-matched (PSM) analysis,two PSM groups (3317 pairs,n = 6634,C-statistic = 0.695) were *** the cumulative incidences of all-cause death,cardiac death,TLR,and non-TVR were similar between the two groups,MACE (HR = 0.832,95% CI: 0.704?0.982,P = 0.030),total revascularization rate (HR = 0.767,95% CI: 0.598?0.984,P = 0.037),and TVR rate (HR = 0.646,95% CI: 0.470?0.888,P = 0.007) were significantly lower in the BB with ACEI group after *** In this study,we suggest that the combination of BB with ACEI may be beneficial for reducing the cumulative incidences of MACE,total revascularization rate,and TVR rather than the BB with ARB after PCI with DES in NSTEMI patients.

AIM: To develop a Fok-I nested polymerase chain reaction(PCR)-restriction fragment length polymorphism analysis(PRA) method for the detection of hepatitis B virus X region(HBx) V5 M ***: Nested PCR was applied into DNAs from 198 chronic patients at 2 different stages [121 patients with hepatocellular carcinoma(HCC) and 77 carrier patients]. To identify V5 M mutants, digestion of nested PCR amplicons by the restriction enzyme Fok-I(GGA TGN9↓) was done. For size comparison, the enzymetreated products were analyzed by electrophoresis on 2.5% agarose gels, stained with ethidium bromide, and visualized on a UV ***: The assay enabled the identification of 69 patients(sensitivity of 34.8%; 46 HCC patients and 23 carrier patients). Our data also showed that V5 M prevalence in HCC patients was significantly higher than in carrier patients(47.8%, 22/46 patients vs 0%, 0/23 patients, P < 0.001), suggesting that HBx Ag V5 M mutation may play a pivotal role in HCC generation in chronic patients with genotype C ***: The Fok-I nested PRA developed in this study is a reliable and cost-effective method to detect HBx Ag V5 M mutation in chronic patients with genotype C2 infection.

AIM： To investigate alternative or subordinate pathways involved in colorectal tumorigenesis and tumor growth, possibly determining at-risk populations and predicting responses to treatment. METHODS： Using microarray gene-expression analysis, we analyzed patterns of gene expression relative to canonical molecular changes and clinicopathological features in 84 sporadic colorectal cancer patients, standardized by tumor location. Subsets of differentially expressed genes were confirmed by real-time reverse-transcript polymerase chain reaction （RT-PCR）. RESULTS： The largest number of genes identified as being differentially expressed was by tumor location, and the next largest number by lymphovascular or neural invasion of tumor cells and by mismatch repair （NMR） defects. Amongst biological processes, the immune response was significantly implicated in entire molecular changes observed during colorectal tumorigenesis （P 〈 0.001）. Amongst 47 differentially expressed genes, seven （PISD, NIBP, BAI2, STOML1, MRPL21, MRPL16, and MKKS） were newly found to correlate with tumorigenesis and tumor growth. Most location-associated molecular changes had distinct effects on gene expression, but the effects of the latter were sometimes contradictory. CONCLUSION： We show that several differentially expressed genes were associated with canonical molecular changes in sporadic colorectal cancers, possibly constituting alternative or subordinate pathways of tumorigenesis. As tumor location was the dominant factor influencing differential gene expression, location-specific analysis may identify location-associated pathways and enhance the accuracy of class prediction.
