Intermolecular duplexes among large nuclear RNAs, and between small nuclear RNA and heterogeneous nuclear RNA, were studied after isolation by a procedure that yielded protein-free RNA without the use...
Changes in nuclear pore complex (NPC) structure are studied following treatments modifying the cisternal calcium levels located between the two lipid bilayers that together form the nuclear envelope. ...
Using sea urchin embryonic and in-vitro-assembled nuclei incubated in sea urchin mitotic extract, I provide evidence for a requirement for functional nuclear pores and a nuclear lamina for nuclear env...
A better understanding of the cellular and molecular events that occur when a nucleus is transferred to the cytoplasm of an oocyte will permit the development of improved procedures for performing nuc...
The molecular mechanisms underlying the nuclear entry of steroid receptors and possible regulation of steroid hormone action during receptor passage across the nuclear envelope have not been elucidate...
Using a proteomic approach, we searched for protein changes dependent on Rho-associated kinase (ROCK) during phorbol-12-myristate-13-acetate (PMA)-induced apoptosis. We found that heterogeneous nuclea...
