Journal Article
Monoclonal antibodies to surface antigens of small cell carcinoma of the lung
Tetsuro Okabe,Tsutomu Kaizu,Michio Fujisawa,Junichi Watanabe,Kayoko Kojima,Tatsuo Yamashita,Fumimaro Takaku +6 more
TL;DR: Four monoclonal antibodies were chosen that demonstrated reactivities with human small cell carcinoma of the lung and not with apparently normal diploid fibroblasts or lymphoblastoid cells, showing binding to the other types of lung cancer and carcinomas derived from other organs, such as colon, pancreas, or stomach.
Journal ArticleDOI
Recombinant human granulocyte colony-stimulating factor induces granulocytosis in vivo.
TL;DR: It is suggested that G-CSF plays a central role in granulocyte production in vivo and the number of progenitor cells was remarkably increased in the spleen.
Journal ArticleDOI
Transforming genes in human leukemia cells
Hisamaru Hirai,Sumiyoshi Tanaka,Mitsuhiko Azuma,Yumi Anraku,Yukio Kobayashi,Michio Fujisawa,Tetsuro Okabe,Akio Urabe,Fumimaro Takaku +8 more
TL;DR: High-molecular weight DNAs of fresh bone marrow cells from 32 patients with fresh leukemia were assayed for the presence of transmissible activated transforming genes by a DNA-mediated gene transfer technique using NIH/3T3 cells and revealed that activation of N-ras oncogenes is independent of the specific stage of cell differentiation or the leukemia phenotype.
Journal ArticleDOI
Activation of the c-K-ras oncogene in a human pancreas carcinoma
TL;DR: Nucleotide sequence analysis suggests that the T3M-4 c-K-ras oncogene has been activated by a single nucleotide transition from A to C in the second exon, which results in the substitution of histidine for glutamine in coden 61 of the predicted amino acid sequence.
Journal ArticleDOI
Establishment of a human colony-stimulating-factor-producing cell line from an undifferentiated large cell carcinoma of the lung.
TL;DR: Results indicate that the two different types of lung cancers produce CSF, which may have stimulated granulopoiesis in vivo in the patients as well.
