“…It is not likely to be due to a failure in our mutation screening method, as its sensitivity has been previously validated in a larger series of tumor DNA samples originating from pancreatic cancer by the identification of KRAS, P16 and DPC4 gene mutations. 33 As suggested by Lievre et al, 27 these discrepancies could reflect the procedure used for the samples' preservation in the study by Kremer-Tal et al, 17 that might increase the risk for false-positive mutated KLF6, compared with the fresh frozen tissue approach that we used here. Other studies found high frequencies of mutations in ovarian and lung cancer that have finally been proved to be artifact because of formalin-fixation.…”

“…Malheureusement cette recherche n'a pas permis le diagnostic de formes débutantes de cancer du pancréas [4,21]. D'autre part, l'analyse concomitante d'autres altérations géniques dans le suc (P16, DPC4, TP53) n'a pas amélioré ces performances [22]. En revanche, le suivi à long terme des patients porteurs de pancréatite chronique et d'une mutation de l'oncogène Kras (10 % des patients étudiés) détectée dans le suc n'a pas révélé d'apparition ultérieure de cancer du pancréas, confirmant peut être le caractère « multi-étapes » de la carcinogenèse pancréatique.…”

“…Discussion TGF-b is well known for its antiproliferative effects, and the neoplastic cells often lose their sensitivity to TGF-b (de Caestecker et al, 2000) and mutations of Smads also contribute to the TGF-b resistance in esophageal, colorectal and pancreatic cancers (Eppert et al, 1996;Hilgers et al, 2000;Tanaka et al, 2000;Costentin et al, 2002;Salovaara et al, 2002). The present study reveals a frame shift mutation (Arg428Ser) of Smad 2 in C-33A as a result of deletion of 'G' in the L3 loop that determines the specificity of Smad-receptor interaction.…”

“…Mutations of Smad 2 and Smad 4 were reported in several cancers (de Caestecker et al, 2000), including pancreatic cancer (Costentin et al, 2002), colorectal cancer (Miyaki et al, 1999) and juvenile polyposis (Howe et al, 1998). However, except for a single report of Smad 4 alteration in SiHa cells (Lee et al, 2001), no information is available on Smad alterations in cervical cancer.…”
