Question: Does a cytotoxic phenotype predict clinical outcome in anaplastic large cell lymphomas?
Answer: In primary biopsies of patients with ALCL, the presence of a cytotoxic phenotype is not related to clinical outcome of the disease.
no

Question: Is nitric oxide-dependent renal vasodilatation altered in rat with rHuEpo-induced hypertension?
Answer: The analysis of our results seems to indicate that the endogenous NO system activity was enhanced in rHuEpo-induced hypertension in rats with normal renal function and a resistance to NO was not developed in renal circulation. Further studies seem to be necessary to better clarify the exact mechanisms underlying the development of rHuEpo-induced hypertension.
no

Question: Does the pro-apoptotic K-Ras 4A proto-oncoprotein affect tumorigenesis in the ApcMin/+ mouse small intestine?
Answer: The K-Ras 4A proto-oncoprotein does not exhibit tumour suppressor activity in the small intestine, even though the K-ras 4A/4B ratio is reduced in adenomas lacking K-ras activating mutations.

no
