Background: Kinesin super family 23 (KIF23) is a member of the KIF family, and it plays an important role in mitosis and cytokinesis. Loss of expression can cause mitotic arrest. The Oncomine database is one of the largest oncogene chip databases in the world, and is an integrated data mining platform for cancer gene information. By querying the database, differences in expression between tumor tissue and normal tissue can be determined.
Aim: To study the expression and prognostic significance of KIF23 in gastric cancer (GC).
Methods: We used immunohistochemistry to compare the expression of KIF23 in GC and normal gastric tissues. We mined the data on the expression and prognosis of KIF23 in GC using Oncomine and Kaplan-Meier plotter database.
Results: Compared with normal gastric tissues, KIF23 expression was increased in GC tissues, and correlated with T, N, and tumor-node-metastasis stages. Survival analysis showed that patients with high expression of KIF23 had a poor overall survival. There were five studies in the Oncomine database in which expression of KIF23 was significantly higher in GC tissues than in normal gastric tissues ( < 0.05). Kaplan-Meier plotter database analysis showed that recurrence-free survival, overall survival, distant metastasis free survival, and post progression survival of patients with high expression of KIF23 were lower than those of patients with low expression. Further stratified analysis found that prognostic survival indicators worsened in patients with T2 and T3 poorly differentiated adenocarcinoma with high expression of KIF23.
Conclusion: KIF23 is highly expressed in GC and is associated with a poor prognosis of patients. It may be of great significance in the diagnosis, treatment, and prognostic evaluation of GC.

Background: Bioinformatics analysis of hepatocellular carcinoma (HCC) expression profiles can aid in understanding its molecular mechanisms and identifying new targets for diagnosis and treatment.
Aim: In this study, we analyzed expression profile datasets and miRNA expression profiles related to HCC from the GEO using R software to detect differentially expressed genes (DEGs) and differentially expressed miRNAs (DEmiRs).
Methods And Results: Common DEGs were identified, and a PPI network was constructed using the STRING database and Cytoscape software to identify hub genes.

Our recently created RNA-sequence-based microRNA (miRNA) expression signature in breast cancer clinical specimens revealed that some family members were significantly downregulated in cancer tissues. Based on TCGA database analyses, we observed that among the family members, (the passenger strand derived from pre-) was significantly downregulated in breast cancer (BC) clinical specimens, and its low expression predicted worse prognoses. Ectopic expression assays showed that transfected cancer cells (MDA-MB-157 and MDA-MB-231) had their aggressive phenotypes significantly suppressed, e.

As a process of intracellular degradation and recycling of its own components, abnormal regulation of autophagy has been strongly associated with the development of multiple cancer types, including triple-negative breast cancer. The amino acid sequences of KIF23 and PRC1 proteins were analyzed by bioinformatics method, their three-dimensional structures were predicted, and their interactions with polysaccharides were studied by molecular docking technology. The localization and expression patterns of KIF23 and PRC1 in cells were studied by cell biology techniques.

Objectives: Resistance to apoptosis in esophageal squamous cell carcinoma (ESCC) constitutes a significant impediment to treatment efficacy. Exploring alternative cell death pathways and their regulatory factors beyond apoptosis is crucial for overcoming drug resistance and enhancing therapeutic outcomes in ESCC.
Methods: Mammalian Ste 20-like kinase 1 (MST1) is implicated in regulating various cell deaths, including apoptosis, autophagy, and pyroptosis.
