A novel class of small RNAs in mouse spermatogenic cells.
Small noncoding RNAs, including small interfering RNAs (siRNAs) and micro RNAs (miRNAs) of approximately 21 nucleotides (nt) in length, have emerged as potent regulators of gene expression at both transcriptional and post-transcriptional levels in diverse organisms. Here we report the identification of a novel class of small RNAs in the mouse male germline termed piwi-interacting RNAs (piRNAs)....
متن کاملHsp70 is present in human saliva.
BACKGROUND There is increasing evidence that chaperones are also present outside the cell, exerting cytokine-like effects and influencing immune recognition. Hsp70 has been found to be present in human blood sera. Chaperonins Cpn10 and Cpn60 are present in pancreatic juice, but Hsp70 is not. These observations raise the possibility that molecular chaperones may be present in other secretory flu...
متن کاملA novel protein, amyloid precursor-like protein 2, is present in human brain, cerebrospinal fluid and conditioned media.
A monoclonal antibody, 3B11, was raised to a novel protein, amyloid precursor-like protein 2, which did not recognize amyloid precursor protein. Multiple bands were detected in human brain fractions and cell lysate by Western blotting, indicating the presence of isoforms, 3B11 immunoreactivity was also detected in cerebrospinal fluid and conditioned medium, indicating that the protein is secret...
متن کاملSpermatogenic cells of the prepuberal mouse: isolation and morphological characterization
A procedure is described which permits the isolation from the prepuberal mouse testis of highly purified populations of primitive type A spermatogonia, type A spermatogonia, type B spermatogonia, preleptotene primary spermatocytes, leptotene and zygotene primary spermatocytes, pachytene primary spermatocytes and Sertoli cells. The successful isolation of these prepuberal cell types was accompli...
متن کاملIsolation of plasma membranes from purified mouse spermatogenic cells.
Plasma membranes have been prepared from purified pachytene spermatocytes, round spermatids and residual bodies of the adult mouse testis using procedures modified from other authors'. Isolated membranes have been examined using electron microscopy, lectin binding and enzymic assays. Ultrastructural observation reveals smooth unit-membrane vesicles from 0.4-1.7 micrometer diameter. No contamina...
