Abstract [en]

Background. Hypoxia-inducible factor (HIF)-2alpha is upregulated in hypoxia or by inactivation of the von Hippel-Lindau (VHL) tumour suppressor gene. In a number of malignancies, increased HIF-2alpha expression may indicate worse prognosis. The aim of this study was to evaluate the prognostic information of HIF-2alpha mRNA expression in renal cell carcinoma (RCC). Material and methods. HIF-2alpha mRNA was quantified by real time polymerase chain reaction (rt-PCR) in tumour tissue samples from 202 patients. Samples from 50 corresponding kidney cortex tissue were analysed as controls. mRNA levels were evaluated in relation to tumour cell type, TNM stage, nuclear grade and disease specific survival. Results. The levels of HIF-2alpha mRNA were significantly higher in 168 clear cell (c)RCC than in 23 papillary (p)RCC (p<0.001) or 11 chromophobe (ch)RCC (p<0.006). Among cRCC there was an inverse correlation between HIF-2alpha mRNA levels and TNM stage I and II-IV tumours (p=0.01), and nuclear grade (p=0.006). After a median follow-up time of 99 months (range 34-247), 106 patients had died of RCC. No correlation of HIF-2alpha mRNA to survival was observed. A multivariate analysis of prognostic factors in cRCC showed that TNM stage alone was an independent predictor of prognosis; HIF-2alpha mRNA levels did not add further prognostic information. Discussion. The results demonstrated that HIF-2alpha mRNA levels were higher in cRCC compared to pRCC and chRCC. Furthermore, HIF-2alpha mRNA levels were inversely related to TNM stage and nuclear grade in cRCC.

Abstract [en]

Transforming growth factor-beta1 (TGF-beta1) inhibits epithelial cell proliferation in the normal prostate. Prostate tumours express high levels of TGF-beta1, and seem to acquire resistance to its anti-proliferative effects with tumour progression. In this study, TGFbeta variations with tumour progression were examined in the Dunning prostatic adenocarcinoma model. Expression of TGF-beta1 and TGFbeta receptor type I and type II (TGFbeta-RI and TGFbeta-RII) in rat dorsolateral prostate (DLP) and Dunning tumour sublines (PAP, AT-1, AT-2, AT-3 and MatLyLu) was examined in vitro and in vivo, using competitive reverse transcription-polymerase chain reaction (RT-PCR), Northern and Western blot, and immunohistochemistry. All tumours expressed elevated levels of TGF-beta1 and TGFbeta-RI mRNA, when compared with the DLP (P < or = 0.05). All tumours except MatLyLu also expressed elevated levels of TGFbeta-RII mRNA (P < or = 0.05). Interestingly, TGFbeta-RII protein levels were very low in the highly metastatic AT-3 and MatLyLu tumours in vivo, when compared with levels in the PAP, AT-1, and AT-2 tumours. This difference was not detected for the AT-1, AT-2, and AT-3 cells in vitro. Immunostaining of TGF-beta1, TGFbeta-RI, and TGFbeta-RII was localised principally in normal and tumour epithelial cells, and occasionally in smooth muscle cells. In conclusion, high expression of TGF-beta1 and TGFbeta-RI and low expression of TGFbeta-RII may contribute to tumour progression and metastasis in the Dunning prostatic adenocarcinoma model.
