Previous studies have indicated that centromere protein K (CENPK) is upregulated in several cancers and related to tumorigenesis. Nevertheless, the potential function of CENPK in gastric cancer (GC) remains unknown. Here, we investigated the function of CENPK on oncogenicity and explored its underlying mechanisms in GC. Our results showed that CENPK was dramatically overexpressed in GC and was associated with poor prognosis through bioinformatics analysis. We demonstrated that CENPK is upregulated in GC tissues and cell lines. Moreover, knockdown of CENPK significantly inhibited proliferation in vitro and attenuated the growth of implanted GCs in vivo. In addition, CENPK silencing induced G1 phase cell cycle arrest and facilitated apoptosis of GC cells. KEGG pathway analysis indicated that the PI3K-AKT signalling pathway was considerably enriched. Knockdown of CENPK decreased the expression of PI3K, p-Akt (Ser437) and p-GSK3β (Ser9) in GC cells, and increased the expression of PTEN. In conclusion, this study indicated that CENPK was overexpressed in GC and may promote gastric carcinogenesis through the PTEN-PI3K-AKT signalling pathway. Thus, CENPK may be a potential target for cancer therapeutics in GC.

Centromere protein K (CENPK) is a newly identified malignancy-related gene that exhibits differential expression in various cancers and plays a crucial role in carcinogenesis. However, it remains uncertain whether CENPK is involved in clear cell renal cell carcinoma (ccRCC). This work aimed to unveil the expression, clinical significance, biological functions, and regulatory mechanisms of CENPK in ccRCC.

Background: The cell cycle gene centromere protein K () is upregulated in various cancers; however, the clinical value and mechanism of in prostate cancer (PCa) and castration-resistant prostate cancer (CRPC) remain unclear.
Methods: The expression of in PCa was analyzed in both patients with PCa and cell lines using immunohistochemistry (IHC), real-time quantitative reverse transcription PCR (qRT-PCR), Western blot and bioinformatics analyses. Knockdown of in PCa cells was achieved by transfecting siRNAs and assessed using qRT-PCR and Western blotting.

Background: Identification of functional genes or biomarkers may be helpful for developing new treatment strategies in lung adenocarcinoma (LUAD). The centromere protein K (CENPK) gene has been discovered to be overexpressed and could influence tumor progression in several tumor types. However, its role in LUAD has never been revealed.
