Silk worm Bm1 SINE RNA increases following cellular insults.
The effect of cell stresses upon the expression of the Bm1 short interspersed element (SINE) family in cultured silk worm cells is examined. Primer extension analysis shows that Bm1 repeats are transcribed by RNA polymerase III (Pol III) into cytoplasmic RNAs. Five consecutive T residues, which would normally terminate Pol III transcription, occur within the Bm1 consensus and are included withi...
متن کاملThe effect of incubation time and silk worm cocoon on mobility of zinc and copper in contaminated clay soil
Of the problematic agents in the ecosystem, heavy metals have special importance because they are unabsorbable and have physiologic effects on living beings at low concentrations. This study has investigated the effect of silk worm cocoon on reducing mobility of zinc (Zn) and copper (Cu) for the first time. To this end, 5% cocoon adsorbent was added to the studied soil, which had been contamina...
متن کاملGrowth of Poultry Chicks Fed on Formulated Feed Containing Silk Worm Pupae Meal as Protein Supplement and Commercial Diet
Waste silkworm pupae (SWP) generate vast resources of nutrients for livestock and poultry. In the present investigation, three days old chicks of RIR strain were allocated to five dietary treatments of silk worm pupae meal. The energy budget was prepared from calculated proximate analysis and growth performance of broiler chicks fed with different percentages of silk worm pupae. The result show...
متن کاملIntroducing Worm
In 1963 Sydney Brenner proposed to study the development of multi-cellular organisms using a genetic approach in a simple animal. He settled on a small, transparent nematode, Caenorhabditis elegans, which develops quickly and is anatomically simple with less than a thousand somatic cells. Almost half a century later there are many more researchers studying C. elegans than there are somatic cell...
متن کاملWorm sensation!
Mechanosensation plays a pivotal role in many aspects of pain pathology, yet the mammalian molecular transduction apparatus responsible for this sensory modality remains unknown. In January's edition of Nature Neuroscience, O'Hagan, Chalfie and Goodman [1] have provided direct electrophysiological evidence that somatic mechanotransduction in C. elegans is mediated by a complex of proteins previ...
