Cancer remains one of the most significant public health challenges worldwide. A widely recognized hallmark cancer is ability to sustain proliferative signaling, which closely tied various cell cycle processes. Centromere Protein (CENPA), a variant standard histone H3, crucial for selective chromosome segregation during cycle. Despite its importance, comprehensive pan-cancer bioinformatic analysis CENPA has not yet been conducted. Data on genomes, transcriptomes, and clinical information were retrieved from publicly accessible databases. We analyzed CENPA's genetic alterations, mRNA expression, functional enrichment, association with stemness, mutations, expression across populations cellular locations, link cycle, impact survival, relationship immune microenvironment. Additionally, prognostic model glioma patients was developed demonstrate potential as biomarker. Furthermore, drugs targeting in cells identified predicted using drug sensitivity correlations protein-ligand docking. exhibited low levels gene mutation cancers. It found be overexpressed nearly all types TCGA, relative normal controls, predominantly located nucleus malignant cells. showed strong particularly biomarker G2 phase. also emerged valuable diagnostic multiple types. In glioma, demonstrated reliable when used alongside other factors. linked Drugs such CD-437, 3-Cl-AHPC, Trametinib, BI-2536, GSK461364 target serves cancers, offering both value.

Background UCK2 (Uridine-Cytidine Kinase 2) is a promising prognostic marker for malignant tumors, but its association with immune infiltration and cancer stemness in pan-cancer remains to be fully understood. we find that gene closed related RNA scores (RNAss) DNA (DNAss), which measured the tumor stemness. We also discover an between expression cells by CIBERSORT algorithm, ESTIMATE algorithm ssGSEA especially, T cell, monocytes, mast cells, macrophages. This study aims shed light on role possible mechanism of pan-cancer.

Abstract Cancer is a complex disease characterized by genetic and molecular diversity, often involving dysregulation of critical cellular pathways. Recent advances in pan-cancer research have highlighted the importance shared oncogenic mechanisms across different cancer types, providing new avenues for therapeutic exploration. Protein kinases, particularly those involved phagocytosis, play pivotal roles homeostasis immune response. This study systematically examines alterations expression profiles protein kinases associated with phagocytosis various using data from The Genome Atlas (TCGA) other publicly available resources. We analyzed single nucleotide variations (SNVs), copy number (CNVs), methylation patterns, mRNA to identify recurring their associations survival outcomes. Our findings reveal that MET MERTK are most frequently mutated genes, missense mutations dominating cancers. CNV analysis shows significant correlations cancers like UCEC, KIRP, KIRC, while indicates cancer-specific regulatory patterns affecting gene expression. Differential highlights distinct cancer-type-specific profiles, genes BTK displaying variation. Crosstalk pathway further reveals involvement these key cancer-related pathways, such as epithelial-mesenchymal transition (EMT) apoptosis. Drug sensitivity identifies potential targets, correlating significantly cell line responsiveness specific compounds. These underscore phagocytotic kinome biology suggest strategies targeting enhance response improve treatment

Bladder cancer is a significant health concern worldwide, necessitating effective diagnostic and monitoring strategies. Biomarkers play crucial role in the early detection, prognosis, treatment of this disease. This review explores current landscape bladder biomarkers, including FDA-approved molecular biomarkers emerging ones. such as BTA stat, TRAK, NMP22, have been instrumental diagnosing cancer. These are derived from urinary samples particularly useful due to their sensitivity specificity. As we move forward, should continue seek ways optimize our processes outcomes, these markers remain seriously challenged detection limited For instance, sensitivities stat tumor varied between 40-72%, while its specificities vary 29-96%. In same way, 70% 80% specificity recorded for 11-85.7% 77-100% documented NMP22 BladderChek. The given variations, especially low diagnosis at an stage call invention better systems. Moreover, different sample collection handling procedures applied laboratories further contribute inconsistent results obtained. Extracellular vesicles (EVs) exosomes, which carry vast number proteins, being considered potential biomarkers. Although show promise, challenges non-standardized isolation techniques lack reproducibility across studies. discovery new ongoing. UBC
