Zusammenfassung: | In recent years, more and more studies have shown that reprogramming lipid metabolism plays an important role in the occurrence and development of hepatocellular carcinoma (HCC). However, there is a lack of systematic exploration of fatty acid (FA) profiles in HCC.
This study aims to systematically investigate the FA profile in HCC and assess the diagnostic potential of stearoyl-CoA desaturase 1 (SCD1) as a biomarker for HCC.
The FA profile in HCC tissues was detected by gas chromatography mass spectrometry. Abnormal FA metabolism was analyzed by qRT-PCR, Western blot. Immunohistochemical and bioinformatics analysis were used to analyze SCD1 expression and function. Receiver operating characteristic curves were used to analyze the diagnostic efficacy of SCD1, and the relationship between SCD1 and immune infiltration in HCC was analyzed by the biological information method.
FAs were found to accumulate in the HCC samples, and abnormal FA metabolism in HCC related to the upregulation of the expression and activity of SCD1. The combination of SCD1 and alpha-fetoprotein produced a greater area under the receiver operating characteristic curve (0.925, P < 0.001) than SCD1 or alpha-fetoprotein alone. It also showed better sensitivity (77.5 %). Besides, high SCD1 expression was found to be related to immune infiltration in HCC.
SCD1 can serve as a reliable biomarker for HCC diagnosis. |
