...Daniel Carrasco; Falk Weih; Rodrigo Bravo ABSTRACT We have studied the expression of the c- rel proto-oncogene during mouse embryonic development and adult animals using in situ hybridization and immunocytochemical analysis. c- rel transcripts were detected late in development with an expression...

...Naren R. Ramakrishna; Anthony M. C. Brown ABSTRACT The segment polarity gene wingless is the Drosophila ortholog of mouse Wni-1, a proto-oncogene capable of causing transformation of mammary epithelial cells. These two genes presently represent the best studied members of the Wnt gene family...

...Suzanne L. Mansour; Judy M. Goddard; Mario R. Capecchi ABSTRACT We derived mice that carry a targeted insertion of a neo r gene in the int-2 ( Fgf-3 ) proto-oncogene coding sequences. The mutation was found to be recessive and mice that were homozygous for the insertion did not often survive...

...Lino Tessarollo; Lalitha Nagarajan; Luis F. Parada The c-ros proto-oncogene is the vertebrate homologue of the Drosophila sevenless tyrosine kinase receptor. Examination of c-ros mRNA transcripts in the mouse embryo reveals a stringent pattern of expression. Only kidney, intestine and lung exhibit...

...Katya Manova; Karl Nocka; Peter Besmer; Rosemary F. Bachvarova Recently, it has been shown that the c-kit proto-oncogene is encoded at the white spotting ( W) locus in mice. Mutations of this gene cause depletion of germ cells, some hematopoietic cells and melanocytes. In order to define further...

...David G. Wilkinson; Sangita Bhatt; Andrew P. Mcmahon The FGF-related proto-oncogene int-2 is implicated in mouse embryogenesis, since it is expressed in specific tissues during gastrulation and neurulation ( Wilkinson et al . 1988 ). Here, we describe the expression of this gene during subsequent...
