New technique reveals drug resistance in breast cancer tumors
...mixture onto fingernail-sized gene chips. The mRNA binds
to its complementary probe on the chip. Afterward, scientists shine a special light on the chip. They can tell by the intensity of light how much messenger RNA -- and hence, copies of each gene -- is present on the chip. Thus, the researchers obtain ...
UT Southwestern Nobelists find protein structure that may help fight high cholesterol
...ke substances that clog arteries. The LDL receptor binds
LDL in the liver and clears it from the blood by pulling cholesterol inside the cells, where it is metabolized to replenish hormones, the cell membrane, vitamin D and other products. "This research will help scientists understand the mechanics of how...

'Knot' to be undone, researchers discover unusual protein structure
...now the protein's function. They speculate that it binds
to RNA, a chemical cousin of the genetic material DNA, and helps process this molecule. The PSI, currently in its pilot phase, expects to move into production phase by the end of 2005. By the end of the pilot phase, each center will aim to produce 1...
Versatile immunosuppressant drug may have new role in radiotherapy for cancer

to a receptor protein (FKBP12) and the rapamycin/FKB12 complex then binds
to mTOR and prevents interaction of mTOR with target proteins in this signalling pathway. "It's alre...

Purdue corrals new Trojan horse to replace wayward genes in mice
...rus G," Sanders said. "It has a protein shell that binds
to just about any kind of cell, which is terrific if you want lots of options for gene therapy. The trouble is, the proteins are toxic to most cells as well, which is, of course, not so good." When the team of Beverly Davidson and Paul McCray at the ...
RRF recycles form, not exact function
...slation? According to Kaji and his colleagues, RRF binds
to different locations within the ribosomal complex at different times. It seems that, if the ribosome is the protein factory, the RRF is the foreman, moving from location to location to 'supervise' the end of the assembly line. When the new protein ...
Revealed: How a master protein remodels chromosomes to orchestrate gene expression
...B1 does not bind to exposed DNA bases; instead, it binds
along the minor groove of double-stranded DNA, where there are well mixed As, Ts, and Cs (cystosine bases) on one strand. While some other proteins, which occur in many cell types, also bind to BURs, SATB1 is cell-type specific; it is found principal...
New insight into fragile X syndrome: Scientists identify possible link to RNAi
...led fragile X mental retardation protein (FMRP) -- binds
to RNA and is thought to regulate the expression of specific genes during neural development, but the mode of FMRP action in cells is yet to be defined. This work provides some important clues. Using Drosophila as a model organism, Drs. Siomi and Ha...
