Considerable controversy surrounds the EMT hypothesis of metastasis, as evidence of EMT is not often detected in tumor pathological preparations [ 22, 24, 25].
The clinical prostate cancer specimens were derived from de-identified archival pathological preparations of the Department of Urology, Hirosaki University, Japan, and analyzed as previously described [ 28].
In support of this hypothesis it should be noted that herein it is shown that the addition of c-Fos both to a non-pathological brain preparation obtained from a GM-patient as well as to the tumor sample stripped of associated proteins (Fig. 2) results in an activated rate of phospholipid synthesis.
Samples preparation, pathological review of tumours and TMA experiments: PG and SP. Management and analysis of clinical and pathological data: AM. miRNA array experiments: ZM, GMF.
TY and AT performed pathological examination and figure preparation.
C Guerin, F Castinetti, C D Micco, D Taieb, F Sebag and A Barlier were responsible for the patient cohorts, clinical and pathological analyses and sample preparation.
Tissue preparation, storage, pathological evaluation, tumor stage assessment according to the UICC 2002, nuclear grading, and data management have been previously described [ 13].
It is concluded that, in epedimiological studies based on routine records, the diagnoses given should always be checked centrally, by experts, in the light of all the available clinical and pathological material (including histological preparations).
SCB: selection, pathological review & validation, manuscript preparation; SR: critical discussion about modeling, data analysis and manuscript preparation.
Most DNAs were extracted within five years after the preparation of the pathological specimens, which ensures the DNA's quality for PCR.
