Spindle component 25 predicts the prognosis and the immunotherapy response of cancers: a pan-cancer analysis.

Spindle component 25 (SPC25) is one of the four proteins that make up the nuclear division cycle 80 (NDC80) complex, the other three components being Ndc80p, Nuf2p, and spindle component 24. Deregulation of the components of this complex can lead to uncontrolled proliferation and reduced apoptosis. However, the prognostic and immunotherapeutic value of SPC25 in pan-cancer remains unclear. Data from the UCSC Xena, TIMER2.0, and TCGA were analyzed to investigate the overall differential expression of SPC25 across multiple cancer types. The survival prognosis, clinical features, and genetic changes of SPC25 were also evaluated. Finally, the relationship between SPC25 and immunotherapy response was further explored through Gene Set Enrichment Analysis, tumor microenvironment, and immune cell infiltration. The transcription and protein expression of SPC25 were significantly increased in most cancer types and had prognostic value for the survival of certain cancer patients such as ACC, CESC, KIRC, KIRP, LIHC, LUAD, MESO, STAD, THYM, and UCEC. In some cancer types, SPC25 expression was also markedly correlated with the TMB, MSI, and clinical characteristics. Gene Set Enrichment Analysis showed that SPC25 was significantly associated with immune-related pathways. In addition, it was also confirmed that the expression level of SPC25 was strongly correlated with immune cell infiltration, immune checkpoint genes, immune regulatory genes, Ferroptosis-related genes, Cuproptosis-related genes, and lactate metabolism-related genes. This study comprehensively explored the potential value of SPC25 as a prognostic and immunotherapeutic marker for pan-cancer, providing new direction and evidence for cancer therapy.

The relationship between maternal periodontal disease and preterm low birth weight / 口腔疾病防治

@# Preterm low birth weight newborns are prone to complications during growth and development, such as growth retardation and infectious diseases, and the mortality rate of high-risk infants is higher than that of healthy newborns. Epidemiological data show that periodontal disease in pregnant women is correlated with preterm low birth weight. Periodontal disease in pregnant women is one of the risk factors for adverse pregnancy outcomes, such as  preterm   low birth weight. This paper addresses the correlation between maternal periodontal disease and  preterm  low birth weight, the influence of periodontal treatment on the incidence of preterm  low birth weight, and premature birth caused by maternal periodontal disease. The mechanism of infant weight is reviewed. The results of this review show that the current studies confirm the correlation between maternal periodontal disease and  preterm low birth weight. However, the causal relationship between maternal periodontal disease and preterm  low birth weight is not fully elucidated, and the specific mechanism and approach are not clear. A possible mechanism is that periodontal pathogens in pregnant women pass through the placental barrier to influence pregnancy outcomes. Therefore, more in-depth research is needed on the specific mechanism, approach, intervention and treatment based on the relationship between these two factors.
