Immunohistochemistry (ABC method) and in situ hybridization (DNA-RNA) were used to detect c-myc and p53 gene expression in tissues of human HCC and nearby non-tumorous liver (NT) from 23 patients. The results showed that the positive rates of P62c-myc were 87% (20/23) in HCC and 91% (21/23) in NT. The positive rates of P53 protein were 39% (9/23) in HCC as well as in NT. The positive rates of c-myc and p53 mRNA were 70% (16/23) and 56% (13/23) in HCC and NT respectively. The expression of c-myc and p53 at protein level was significantly correlated with that at mRNA level. These observations suggest a close association of c-myc and p53 gene overexpression with hepatocarcinogenesis. Immunohistochemistry (ABC method) on section of paraffin embedded tissue is a reliable method for detecting c-myc and p53 gene expression in HCC.

D006528	Carcinoma, Hepatocellular	A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.

D012333	RNA, Messenger	RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

D016259	Genes, myc	Family of retrovirus-associated DNA sequences (myc) originally isolated from an avian myelocytomatosis virus. The proto-oncogene myc (c-myc) codes for a nuclear protein which is involved in nucleic acid metabolism and in mediating the cellular response to growth factors. Truncation of the first exon, which appears to regulate c-myc expression, is crucial for tumorigenicity. The human c-myc gene is located at 8q24 on the long arm of chromosome 8.
