  • One response
A flu vaccine during pregnancy protects the children and women from illness, but does it also have long-term risks? A decade-long follow-up study refutes this.

Nanotechnological development significantly improves the effectiveness of skin cancer treatment

  • One response
The development by researchers at Tel Aviv University, which was tested on animals, doubled the therapeutic effectiveness of the drugs and made it possible to reduce by a third the dose of drugs injected into the body
When the NXF1 protein is in the cells properly (left), the RNA molecules (orange dots) of a particular single-exon gene are exported from the nucleus (marked in purple) into the cell fluid. When NXF1 is silenced (right), RNA molecules are mostly stuck in the nucleus

Export in the slow route

  • No comments
The "export" of RNA from the cell nucleus - a necessary process in the creation of proteins and the existence of life in a cell with a nucleus - was previously considered to be uniform and fast. In a new study, Weizmann Institute of Science scientists revealed that there are at least two pathways for RNA export, and that the cell can inhibit certain RNA molecules in the nucleus, while others go out into the cell fluid in the fast and familiar pathway
