- 1990
The ret proto-oncogene expresses four major mRNA species of different lengths in human malignant cell lines and rat tissues. We isolated ret proto-oncogene cDNA clones from a cDNA library of a human… Expand
Detection of the PTC/retTPC oncogene in human thyroid cancers.

- 1 July 1992
We have investigated the PTC/retTPC oncogene, an activated form of ret proto-oncogene with a specific rearrangement, in thyroid malignancies. Southern analysis was used to screen 36 thyroid papillary… Expand
Human ret proto-oncogene mapped to chromosome 10q11.2.

- 1 December 1989
Using cosmid clones derived from human ret protooncogene as probes, we determined its chromosome localization by fluorescence in situ hybridization. Two overlapping clones, cret-1 and -2, which were… Expand
Outside-to-Inside Signal Through the Membrane TNF-α Induces E-Selectin (CD62E) Expression on Activated Human CD4+ T Cells1

The membrane TNF-α is known to serve as a precursor of the soluble form of TNF-α. Although it has been reported the biological functions of the membrane TNF-α as a ligand, the outside-to-inside… Expand
Expression of proto-ret mRNA in embryonic and adult rat tissues.

- 30 June 1988
The expression of proto-ret mRNA in adult and embryonic rat tissues were studied. Very low levels of proto-ret transcripts were found in adult rat tissues such as brain, thymus and testis. The sizes… Expand
Expression of the ret proto-oncogene in human neuroblastoma cell lines and its increase during neuronal differentiation induced by retinoic acid.

- Biology, Medicine
- Oncogene
- 1 December 1991
Previously we observed specific expression of the ret proto-oncogene (proto-ret) in human neuroblastoma cell lines. A neuronal subline and non-neuronal sublines were isolated from the SK-N-SH cell… Expand
Identification and analysis of the ret proto-oncogene promoter region in neuroblastoma cell lines and medullary thyroid carcinomas from MEN2A patients.

- 1 June 1992
The human ret proto-oncogene (proto-ret), encoding a receptor tyrosine kinase, is highly expressed in neuroblastomas, medullary thyroid carcinomas (MTCs) and pheochromocytomas, which are all tumors… Expand
Presence of Aberrant Transcripts of ret Proto‐oncogene in a Human Papillary Thyroid Carcinoma Cell Line

- Japanese journal of cancer research : Gann
- 1 December 1989
In a papillary thyroid carcinoma cell line, TPC‐1, we found transcripts hybridizing to ret proto‐oncogene (proto‐ret) cDNA probes. The transcripts hybridized to the probes encoding the kinase domain… Expand
Nakahara memorial lecture. New classes of tumor promoters: teleocidin, aplysiatoxin, and palytoxin.

- Chemistry, Medicine
- Princess Takamatsu symposia
- 1983
Teleocidin and aplysiatoxin, which are structurally different from 12-O-tetradecanoylphorbol-13-acetate (TPA), were found to be potent tumor promoters in two-step mouse skin carcinogenesis. The class… Expand
Structure of the c-Ki-ras gene in a rat fibrosarcoma induced by 1,8-dinitropyrene.

- 1 April 1986
Restriction enzyme maps were made of the region around exons 1 and 2 of activated c-Ki-ras of a fibrosarcoma (1,8-DNP2) induced in a rat by 1,8-dinitropyrene. Nucleotide sequence analysis revealed… Expand
