Ribosomopathies encompass a spectrum of disorders arising from impaired ribosome biogenesis and reduced functionality.Mutation or dysexpression of the genes that disturb any finely regulated steps of ribosome biogenesis can result in different types of ribosomopathies in clinic,collectively known as ribosomopathy genes.Emerging data suggest that ribosomopathy patients exhibit a significantly heightened susceptibility to cancer.Abnormal ribosome biogenesis and dysregulation of some ribo-somopathy genes have also been found to be intimately associated with cancer development.The cor-relation between ribosome biogenesis or ribosomopathy and the development of malignancies has been well established.This work aims to review the recent advances in the research of ribosomopathy genes among human cancers and meanwhile,to excavate the potential role of these genes,which have not or rarely been reported in cancer,in the disease development across cancers.We plan to establish a theoretical framework between the ribosomopathy gene and cancer development,to further facilitate the potential of these genes as diagnostic biomarker as well as pharmaceutical targets for cancer treatment.

Abstract: Objective By analyzing the monitoring results of rodents in Hainan Province in 2022, the species composition, distribution, seasonal fluctuation, and density of rodents were understood and mastered, and the correlation between rodent density and meteorological factors in Haikou was explored, so as to provide a scientific basis for vector control and prevention and control of rodent-borne infectious diseases. Methods Using the night cage method, according to the "2022 Hainan Province Rodent Monitoring Implementation Plan”, monitoring was conducted in 17 cities and counties every two months starting from January. Excel 2021 software was used to sort out the monitoring data and draw the chart, and SPSS 26.0 was used for statistical analysis. Spearman correlation analysis was used for the correlation between rodent density and meteorological factors. Results In 2022, the overall rodent density in Hainan Province was 4.32% (1 166/27 008). Brown rat (Rattus norvegicus) was the dominant species, accounting for 72.21% (842/1 166) of the total captures. In terms of area, the highest rodent density was 27.27% (367/1 346) in Changjiang County, followed by Haikou, Wanning, and Sanya, with rodent densities of 8.59% (155/1 804), 6.55% (77/1 176), and 5.11% (81/1 586), respectively. Different habitat types had different rodent densities, with the highest in rural residential areas at 4.49% (402/8 962); key industries (dining, food manufacturing and sales, construction sites, slaughtering, brewing, etc.) had a density of 4.41% (404/9 153); and urban residential areas had a density of 4.05% (360/8 893). In terms of seasonal fluctuation, the overall rodent density showed a downward trend after reaching its peak in May. The peak rodent density in rural residential areas was in July (5.73%), there was no distinct peak period in urban residential areas, and the peak period for key industries occurred in May (6.87%). Spearman correlation analysis showed that the rodent density in Haikou was positively correlated with average temperature and accumulated sunshine time (r=0.90, 0.9; P<0.05). Conclusions The density of rodents in Hainan Island is relatively high. Cities and counties need to compare annual monitoring data to reasonably assess the risk and formulate appropriate control measures according to the actual local situation.

Deubiquitinating enzymes (DUBs) or deubiquitinases facilitate the escape of multiple proteins from ubiquitin‒proteasome degradation and are critical for regulating protein expression levels in vivo. Therefore, dissecting the underlying mechanism of DUB recognition is needed to advance the development of drugs related to DUB signaling pathways. To data, extensive studies on the ubiquitin chain specificity of DUBs have been reported, but substrate protein recognition is still not clearly understood. As a breakthrough, the scaffolding role may be significant to substrate protein selectivity. From this perspective, we systematically characterized the scaffolding proteins and complexes contributing to DUB substrate selectivity. Furthermore, we proposed a deubiquitination complex platform (DCP) as a potentially generic mechanism for DUB substrate recognition based on known examples, which might fill the gaps in the understanding of DUB substrate specificity.

Synthetic lethality is a proven effective antitumor strategy that has attracted great attention. Large-scale screening has revealed many synthetic lethal genetic phenotypes, and relevant small-molecule drugs have also been implemented in clinical practice. Increasing evidence suggests that CDKs, constituting a kinase family predominantly involved in cell cycle control, are synthetic lethal factors when combined with certain oncogenes, such as

Objective:To analyze the clinical characteristics of patients suffering from acute ischemic stroke (AIS) complicated with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods:Data of patients with AIS who visited the Second Affiliated Hospital of Soochow University from January 2015 to June 2020 and underwent polysomnography monitoring (PSG) in the sleep center were collected retrospectively. Patients were divided into OSAHS group and AIS only group. Demographic information of patients, general clinical data, hematological indicators of glucose and lipid metabolism and inflammatory markers, PSG parameters and neurological function scores were collected, including the National Institutes of Health Stroke Scale (NIHSS) on admission and the modified Rankin Scale (mRS) on discharge. We compared the differences between the two groups. In addition, OSAHS group were divided into good prognosis and poor prognosis subgroups according to mRS score. The differences between the two subgroups were compared.Results:A total of 112 AIS patients combined with OSAHS and 89 AIS only patients were included. The proportion of non-rapid eye movement stages 1+2 [(N1+N2) %], arousal index, the oxygen desaturation index (ODI), percentage of total sleep time with oxygen saturation<90% (TS90) in the OSAHS group were higher than those in the AIS only group, while N3%, lowest nocturnal oxygen saturation (LSaO 2) were lower (all P<0.05). There was no statistical difference in the distribution of cerebral apoplexy lesions (cortex, subcortical, brainstem, cerebellum) between the two groups, but the proportion of patients with multifocal cerebral apoplexy in the OSAHS group was higher ( P=0.032). There was no statistical difference in NIHSS score on admission between the two groups, but the neutrophil/lymphocyte ratio (NLR) score ( P=0.004) and mRS score on discharge ( P=0.010) of the OSAHS group were significantly higher than those in the AIS only group. There were 74 patients in the good prognosis group and 38 in the poor prognosis group. The analysis showed that the NIHSS and NLR scores of the poor prognosis group were higher than the good prognosis group, admission NIHSS score was a risk factor for poor prognosis, all P<0.01. Conclusions:AIS patients complicated with OSAHS are characterized by disordered sleep structure, more severe nocturnal hypoxia, higher risk of developing multiple lesions, poor neurological function recovery at discharge, and high inflammatory index of NLR. Among them, patients with poor prognosis have poorer sleep efficiency, and high admission NIHSS score is a risk factor for poor prognosis.

The membrane protein claudin-3 (CLDN3) is critical for the formation and maintenance of tight junction and its high expression has been implicated in dictating malignant progression in various cancers. However, the post-translational modification of CLDN3 and its biological function remains poorly understood. Here, we report that CLDN3 is positively correlated with ovarian cancer progression both and Of interest, CLDN3 undergoes -palmitoylation on three juxtamembrane cysteine residues, which contribute to the accurate plasma membrane localization and protein stability of CLDN3 Moreover, the deprivation of -palmitoylation in CLDN3 significantly abolishes its tumorigenic promotion effect in ovarian cancer cells. By utilizing the co-immunoprecipitation assay, we further identify ZDHHC12 as a CLDN3-targating palmitoyltransferase from 23 ZDHHC family proteins. Furthermore, the knockdown of ZDHHC12 also significantly inhibits CLDN3 accurate membrane localization, protein stability and ovarian cancer cells tumorigenesis Thus, our work reveals -palmitoylation as a novel regulatory mechanism that modulates CLDN3 function, which implies that targeting ZDHHC12-mediated CLDN3 -palmitoylation might be a potential strategy for ovarian cancer therapy.

Objective:
To investigate whether diffusion tensor imaging (DTI) and motor evoked potentials (MEP) can be used as biomarkers to assess the degree of motor dysfunction of stroke survivors.
Methods:
Sixty partially-paralyzed stroke survivors were given Fugl-Meyer assessments (FMAs) and MEP tests and assessed using DTI seeking any correlations among the results. The receiver operating characteristics curves (ROCs) were prepared to determine the tests′ efficacy in assessing severe motor dysfunction.
Results:
① Asymmetry in the fractional anisotropy (aFA) of the peduncles cerebra as measured by DTI was negatively correlated with the FMA scores of the upper and lower limbs on the affected side. The aFA values of the posterior limb of the internal capsule (PLIC) were negatively correlated with the FMA scores of the affected upper limb, but not with the FMA scores of the affected lower limbs. The abnormalities in central motor conduction time and motor threshold, which are MEP parameters, were negatively correlated with the FMA scores of the affected limbs. ② The ROCs showed that the aFA value of the PLIC was the best indicator for assessing severe upper limb motor dysfunction, with a cut-off value of 0.167 giving the best discrimination. MEP waveform loss could also be used. It has high sensitivity but low specificity. ③ A combination of DTI and MEP can improve specificity in assessing severe motor dysfunction in the upper limbs.
Conclusion
DTI and MEP can both be used to evaluate motor dysfunction in stroke survivors. They have high clinical value for assessing severe motor dysfunction of the upper limbs.
