The immunohistochemical staining method Methods: was used to detect the expression of Hsp90AB1 in HCC tissue chip. Bioinformatics analysis technology was used to analyze the HCC related gene chip GSE54238; the expression of gene in normal liver tissues and Hsp90AB1 HCC tissues were analyzed using the database GEPIA, and the survival analysis of HCC patients based on the expression difference of Hsp90AB1 was performed. qRT-PCR was used to detect the expression of Hsp90AB1 gene in normal liver cell lines and liver cancer cell lines. Immunohistochemical experiment showed that Results: Hsp90AB1 was up-regulated in HCC tissues compared with normal liver tissues ( <
