Cell division cycle 45 (CDC45) is an essential protein required for the initiation of DNA replication. In the present study, the role of CDC45 across 33 cancers was systematically investigated. It was observed that the expression of CDC45 was significantly upregulated in most cancers, exhibiting a marked negative correlation with the overall survival. Next, there was no significant difference in prognosis between the genomically altered and unaltered groups with respect to clinical outcomes. A decreased level of CDC45 at the DNA promoter region was also identified in several cancers. Furthermore, CDC45 expression was associated with the levels of tumor‑infiltrating immune cells in some specific cancer types. In addition, CDC45 was associated with mA methylation, and CDC45 expression was primarily positively correlated with 'writers' and 'readers' in various cancers, particularly HNRNPC, RBM15 and YTHDC1. Gene enrichment analysis was also performed. In addition, the AUC of each cancer with respect to its 1‑, 3‑, and 5‑year survival rates were explored. Finally, CCK‑8 assays, EdU assays and cell cycle analysis were conducted. In conclusion, the present study demonstrated that CDC45 may be a potential biomarker and target for cancer treatment.

PEDV is a highly contagious enteric pathogen that can cause severe diarrhea and death in neonatal pigs. Despite extensive research, the molecular mechanisms of host's response to PEDV infection remain unclear. In this study, differentially expressed genes (DEGs), time-specific coexpression modules, and key regulatory genes associated with PEDV infection were identified.

In spite of being dispensable for catalysis, Dpb2, the second largest subunit of leading strand DNA polymerase (Polymerase ε) is essential for cell survival in budding yeast. Dpb2 physically connects polymerase epsilon with the replicative helicase (CMG,Cdc45-Mcm-GINS) by interacting with its Psf1 subunit. Dpb2-Psf1 interaction has been shown to be critical for incorporating polymerase ε into the replisome.

Purpose: The aim of this study was to elucidate the effect of itaconate (ITA) on experimental autoimmune uveitis (EAU), to explore its potential mechanism, and to identify potential therapeutic targets.
Methods: We established an animal model of EAU by constructing an immune map of mice treated with ITA and exploring the therapeutic mechanism of ITA by single-cell RNA sequencing and flow cytometry.
Results: ITA mitigated ocular inflammation associated with EAU and reversed the pathogenic differentiation linked to Th17 induction by EAU, along with the reactive oxygen species (ROS) and oxidative stress pathways.

Background: Human papillomavirus (HPV)-induced cervical cancer progresses through a series of steps. Despite our limited understanding of the mechanisms driving this progression, identifying the key genes involved could significantly improve early detection and treatment.
Materials And Methods: Two gene expression profiles of GSE9750 and GSE6791, which included cervical cancer HPV-positive and -negative samples, were evaluated using the R limma package with established cut-off criteria of value < 0.

Article Synopsis
- Histone recycling from parental DNA to new strands is crucial for passing down epigenetic information during chromatin replication.
- An experiment showed that disrupting the interaction between Mcm2 and a histone complex affects recycling, but more details about the specific mechanisms involved are still unknown.
- Simulations of yeast DNA replication revealed that histones can be recycled through different pathways and that the binding of RPA influences how much is recycled to each strand, while DNA bending by Pol ε affects where the histones end up.
