Role and mechanism of protein kinase C-β in inhibiting the proliferation of hepatocellular carcinoma cells
To investigate the potential role of protein kinase C-β(PRKCB/PKC-β) in hepatocellular carcinoma(HCC) and reveal the possible molecular mechanisms underlying the occurrence and development of HCC.
Methods
2
Liver cancer-related data from the TCGA and GEO databases were integrated to analyze the correlation between PRKCB expression and clinical prognosis in HCC. In HCC cell lines,PRKCB was overexpressed or silenced,and its impact on HCC proliferation was assessed using cell proliferation and colony formation assays. Western blotting was used to detect PRKCB expression levels in tumor tissues and adjacent non-tumor tissues from clinical HCC samples,and to investigate the molecular mechanism by which PRKCB affects HCC cell proliferation.
Results
2
PRKCB expression was low in HCC cell lines(
P
<
0.05) and its low expression wa
s associated with poor patient prognosis(
P
<
0.05). Overexpression of PRKCB inhibited HCC proliferation,whereas silencing PRKCB increased the proliferative capacity of HCC cells(
P
<
0.05). Altered PRKCB expression led to significant changes in the phosphorylation levels of ERK,p38,and JNK,thereby affecting the occurrence and development of HCC.
Conclusion
2
PRKCB can inhibit the proliferative capacity of HCC. This effect may be mediated by regulating the MAPK signaling pathway related to the phosphorylation levels of ERK1/2,p38,and JNK.
