Selective inhibition of cell growth by activin in SNU-16 cells.
Seoul, South Korea. In World J Gastroenterol, 2006
Basal level of inhibin/activin subunits, activin receptors, Smads, and p21(CIP1/WAF1) except for activin betaB mRNAs was observed to have differential expression patterns in the human gastric cancer cell lines, AGS, KATO III, SNU-1, SNU-5, SNU-16, SNU-484, SNU-601, SNU-638, SNU-668, and SNU-719.
Drivers of germ cell maturation.
Melbourne, Australia. In Ann N Y Acad Sci, 2005
We examined the in vivo impact of activin on testis development using two mouse models, the inhba-/- mouse (which lacks the gene encoding the activin A subunit and dies at birth) and BK mice, with inhbb (encoding the activin betaB subunit) replacing inhba (which survive to adulthood and show delayed fertility onset in males).
Asymmetry: molecular, biologic, embryopathic, and clinical perspectives.
Halifax, Canada. In Am J Med Genet, 2001
This overview of asymmetry addresses the following topics: chiral molecules; asymmetric signaling molecules, including N-cadherin, Shh, Fgf8, lefty1, lefty2, nodal, Pitx2, activin betaB, activin receptor IIA, and cSnR; situs abnormalities; asymmetric cell division; laterality in humans and animals; behavioral asymmetry in humans and animals; asymmetric embryopathies, including Tessier-type "clefts"; hemiasymmetries such as hemihyperplasia, hemihypoplasia, and hemiatrophy; asymmetric vascular syndromes, including Klippel-Trenaunay and Sturge-Weber syndromes; plagiocephaly of the synostotic and deformational types; somatic mosaicism, including a discussion of McCune-Albright syndrome, fibrous dysplasia, GNAS1 mutations, and Proteus syndrome.
Studying TGF-beta superfamily signaling by knockouts and knockins.
Houston, United States. In Mol Cell Endocrinol, 2001
We found that activin betaB, expressed in the spatiotemporal pattern of activin betaA, can function as a hypomorphic allele of activin betaA and rescue the craniofacial defects and neonatal lethal phenotype of activin betaA-deficient mice.
