A form of runt disease has been produced in neonatal CF-1 and ICR mice by the repeated injection of 10(9) washed, autoclaved, saline-suspended staphylococci or streptococci. The most severely affected animals showed a marked decrease in lymphoid tissues and resembled grossly and microscopically animals suffering from the classical runt or wasting disease described by others. The timing of the i...

The initial metameric expression of the Drosophila sloppy paired 1 (slp1) gene is controlled by two distinct cis-regulatory DNA elements that interact in a nonadditive manner to integrate inputs from transcription factors encoded by the pair-rule segmentation genes. We performed chromatin immunoprecipitation on reporter genes containing these elements in different embryonic genotypes to investi...

The Runt related transcription factors (RUNX) are recognized as key players in suppressing or promoting tumor growth. RUNX3, a member of this family, is known as a tumor suppressor in many types of cancers, although such a paradigm was challenged by some researchers. The TGF-β pathway governs major upstream signals to activate RUNX3. RUNX3 protein consists of several regions and domains. The Ru...

Two experiments were conducted to examine the effects of prenatal stunting on skeletal muscle and adipose tissue cellularity in swine at 96 and 109 kg live weight. Animals used in Exp. 1 were large (1.56 kg average birth weight) and runt (.97 kg) littermate pigs and pigs with very low birth weight (.79 kg). The pigs with very low birth weight were half sibs to the large and runt littermates. Pi...

The Drosophila CNS contains a variety of glia, including highly specialized glia that reside at the CNS midline and functionally resemble the midline floor plate glia of the vertebrate spinal cord. Both insect and vertebrate midline glia play important roles in ensheathing axons that cross the midline and secreting signals that control a variety of developmental processes. The Drosophila midlin...

One of the possible consequences of the graft-versus-host reaction (GVHR) 1 in animals and man is runt disease or acute graft-versus-host (GVH) disease (GVHD). It is frequently fatal and produces a variety of symptoms, which include atrophy of the skin and the gastrointestinal mucosa and hypoplasia of the hemopoietic and lymphoid tissues manifested by anemia and immunodeficiency, respectively (...
