ABSTRACT

Objective:To analyze the relationship between the expression and prognosis of kinesin family member 4A (KIF4A) in renal clear cell carcinoma and explore its potential mechanism.Methods:Information on the KIF4A gene in renal clear cell carcinoma was retrieved from the UALCAN database, including expression levels, survival analysis, and positive and negative correlation gene data, from which the expression levels, prognostic information, and potential mechanisms of KIF4A in renal clear cell carcinoma were derived.Results:KIF4A is highly expressed in renal clear cell carcinoma, and male patients have a higher expression rate than female patients. The higher the tumor grade and the later the N stage, the more expression ( P<0.05). The survival analysis showed that the expression level and prognosis of KIF4A were negatively correlated ( P<0.05). Cyclin B2 (CCNB2), kinesin family member 23 (KIF23), cell division cycle associated 5 (CDCA5), and KIF4A were significantly positively correlated, whereas DHRS12, crumbs protein homolog 3 (CRB3), β-hydroxybutyrate dehydrogenase 2 (BDH2), and KIF4A were significantly negatively correlated. Conclusions:KIF4A plays an important role in the development of renal clear cell carcinoma and can be used as a potential marker and therapeutic target for the diagnosis and prognosis of renal clear cell carcinoma, including in children.

ABSTRACT

Background: As one of the most common malignant tumors of the digestive tract, esophageal squamous cell carcinoma (ESCC) is an advanced metastatic cancer with an extremely high mortality rate and the highest prevalence rate in China. Spindle- and kinetochore-associated protein 1 (SKA1), an essential member involved in chromosome separation during mitosis, has been indicated as a potential biomarker in the pathogenesis and development of various types of malignant tumors; however, the exact functions of SKA1 in ESCC are still unclear. Patients and Methods: SKA1 expression was explored in stage IIA ESCC and corresponding healthy esophageal mucosa tissues through immunohistochemistry and reverse transcription–quantitative polymerase chain reaction and was further validated using The Cancer Genome Atlas (TCGA) database of the online tool UALCAN. Then, the clinicopathological correlations of SKA1 were analyzed based on the follow-up data. Furthermore, using the online tool LinkedOmics, the correlation test, gene ontology (GO), and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis of SKA1 were analyzed using high-throughput sequencing data of ESCC patients from TCGA dataset. Results: The expression level of SKA1 was markedly upregulated in ESCC tissues. Upregulation of SKA1 significantly correlated with higher pathological T stage (P = 0.003) and poorer overall survival (P = 0.013). GO and pathway enrichment analyses of SKA1 in ESCC revealed that SKA1 was involved in a number of classical cell cycle-related pathways that contribute to special biological processes in tumorigenesis and development of ESCC. Conclusion: The results of this study demonstrate that SKA1 may act as a prognostic biomarker for stage IIA ESCC. Combined with the bioinformatic analysis, SKA1 could potentially serve as a therapeutic target for ESCC. Conclusion: The results coming from the present study demonstrated that SKA1 may act as a prognostic biomarker for stage IIA ESCC. Combined with the bioinformatic analysis, SKA1 could serve as a potential therapeutic target for ESCC

ABSTRACT

Objective To discuss the expression of caspase-7 (CASP7) and its prognostic role in colon cancer. Methods CASP7 expression data was retrieved from Ualcan database, and the survival data of CASP7 down-regulated colon cancer patients was retrieved from Ualcan database and Oncolnc database. Results In colon cancer, the expression of CASP7 was down-regulated and indicated a relatively worse prognosis. The expression of CASP7 was correlated with KRAS and TP53I3. Conclusions CASP7 is down-regulated in colon cancer and indicates a worse prognosis.
