... L-Arginyl-L-tyrosine (retro-isomer of KTP, Ret-KTP) was purchased from Bachem Feinchemikalien AG (Switzerland).
NTRK fusion oncogenes in pediatric papillary thyroid carcinoma in northeast United States.
Bologna, Italy. In Cancer, Feb 2016
Six of 27 PTCs (22%) had ret proto-oncogene (RET) fusions (RET/PTC1, n = 5; RET/PTC3, n = 1); 2 tumors measured >2 cm and diffusely involved the thyroid, and 5 had lymphatic invasion, with vascular invasion in 2. Thirteen PTCs had the B-Raf proto-oncogene, serine/threonine kinase (BRAF) valine-to-glutamic acid mutation at position 600 (BRAF(V) (600E) ) (13 of 27 tumors; 48%), 11 measured <2 cm, and 6 had lymphatic invasion (46%), with vascular invasion in 3. Fusion oncogene tumors, compared with BRAF(V) (600E) PTCs, were associated with large size (mean, 2.2 cm vs 1.5 cm, respectively; P = .05),
Lenvatinib: Role in thyroid cancer and other solid tumors.
Houston, United States. In Cancer Treat Rev, Jan 2016
Lenvatinib targets vascular endothelial growth factor receptors 1-3 (VEGFR1-3), fibroblast growth factor receptors 1-4 (FGFR-1-4), RET, c-kit, and platelet-derived growth factor receptor α (PDGFRα).
Mechanical induction of the tumorigenic β-catenin pathway by tumour growth pressure.
Paris, France. In Nature, Aug 2015
In the early stage of mouse colon tumour development in the Notch(+)Apc(+/1638N) mouse model, we observed mechanistic pressure stress in the non-tumorous epithelial cells caused by hyper-proliferative adjacent crypts overexpressing active Notch, which is associated with increased Ret and β-catenin signalling.
Lenvatinib versus placebo in radioiodine-refractory thyroid cancer.
Aş Şanamayn, Syria. In N Engl J Med, Mar 2015
BACKGROUND: Lenvatinib, an oral inhibitor of vascular endothelial growth factor receptors 1, 2, and 3, fibroblast growth factor receptors 1 through 4, platelet-derived growth factor receptor α, RET, and KIT, showed clinical activity in a phase 2 study involving patients with differentiated thyroid cancer that was refractory to radioiodine (iodine-131).
Anchored multiplex PCR for targeted next-generation sequencing.
Boston, United States. In Nat Med, 2014
On the basis of our experience with performing AMP on 986 clinical FFPE samples, we show its potential as both a robust clinical assay and a powerful discovery tool, which we used to identify new therapeutically important gene fusions: ARHGEF2-NTRK1 and CHTOP-NTRK1 in glioblastoma, MSN-ROS1, TRIM4-BRAF, VAMP2-NRG1, TPM3-NTRK1 and RUFY2-RET in lung cancer, FGFR2-CREB5 in cholangiocarcinoma and PPL-NTRK1 in thyroid carcinoma.
