Ene was initially identified as an immediately-early gene of mouse 3T3 fibroblasts, and was also discovered to be expressed in establishing mouse cartilaginous elements and placental tissues[14]. CTGF was initially identified within the conditioned culture medium of human umbilical vein endothelial cells, and revealed to become induced by transforming development factor in human skin fibroblasts. Nov gene was identified as an aberrantly expressed gene in avian nephroblastomas induced by myeloblastosis-associated viruses. The overexpression of Nov gene was reported relative to human Anti-Mullerian Hormone Receptor Type 2 Proteins Biological Activity Wilsm’s tumors. Taking cues from clinical observations and final results of our laboratory researches, we have hypothesized that solitary significant hepatocellular carcinoma (SLHCC) possesses somewhat better biological behaviors[15]. Moreover, we’ve got preliminarily proved our hypothesis by a IL-1 Receptor Accessory Proteins custom synthesis series of researches[16]. The clinical pathological features of SLHCC have been better than nodular hepatocellular carcinoma (NHCC) as well as the molecular biological study also suggested that SLHCC possessed improved molecular pathological features. Cyr61, CTGF and Nov gene may possibly overexpress in HCCs. In this report, we studied the expressions of Cyr61, CTGF and Nov genes in HCCs and para-cancerous normal liver tissues, to clarify whether or not these genes might play a crucial part inside the recurrence and metastasis of HCCs. Additionally, we examined the expressions of Cyr61, CTGF and Nov genes in SLHCC, NHCC and SHCC and compared their variations. Supplies AND Approaches Sufferers and tissue preparation Thirty-one fresh HCC specimens and corresponding paracancerous liver tissues were obtained by surgical resection athttp://www.wjgnet.com/1007-9327/10/3414.aspZeng ZJ et al. Cyr61, CTGF and Nov in hepatocellular carcinomaXiangya Hospital among March 2002 and March 2003. The individuals with HCC consisted of 26 guys and five girls along with the age of them ranged from 21 to 69 years (mean, 48 years). The individuals had been classified as SHCC (tumor largest diameter five cm for any single tumor nodule or the sum of diameters 5 cm for two tumor nodules), SLHCC (a single tumor nodule and tumor biggest diameter five cm), NHCC (the nodules of tumor 2, only two tumor nodules and the sum of diameters five cm have been excluded). Moreover, we divided 31 specimens into six groups: tumors 5 cm diameter and five cm, grade I-II and grade III-IV, liver cirrhosis and no liver cirrhosis, capsule formation and no capsule formation, microscopic portal vein tumor thrombosis and no microscopic portal vein tumor thrombosis. All specimens were examined below a microscope just after haematoxylin and eosin (HE) staining.Outcomes Expression of Cyr61, CTGF and Nov mRNA in HCC and paracancerous liver tissues The expressions of Cyr61 and CTGF mRNA in HCC tissues have been considerably larger than those in para-cancerous typical liver tissues. The expression of Nov gene was larger than that in para-cancerous standard liver tissues (Table 1). The difference in Nov gene expression involving these two groups did not attain statistical significance. The expressions of Cyr61, CTGF and Nov genes are shown in Figure 1.Table 1 Expression of Cyr61, CTGF and Nov mRNA in HCC and para-cancerous liver tissues (mean D)n HCC 31 Para-cancerousbCyr61 2.34.46 0.48.bCTGF 2.21.34 0.65.bNov 1.56.21 0.89.RNA extraction and RT-PCR Total RNA was isolated making use of Trizol reagent (GIBCO BRL, USA) and cDNA was synthesized from RNA by M-MLV reverse transcriptase (Promega, USA) with oligo-dT primers (Sango Technologies, China).
