Remote control for human growth hormone gene expression

...er. By carefully analyzing the 14,000 base pairs separating the hGH gene and its locus control region, co-authors Yugong Ho, PhD, an Instructor of Genetics at Penn and a Cooke/Liebhaber lab member, and Felice Elefant, PhD, Assistant Professor at Drexel University and former member of the Cooke/Liebhaber lab, ...

Researchers identify human DNA on the fast track

...egion's 118 bases changed in the 310 million years separating the evolutionary lineages of the chicken and the chimp. Incredibly, since the human lineage separated from that of the chimp, 18 of the 118 nucleotides have changed. This region "stood out," said Pollard. But what does it do? To find out, Pollard be...

New Queen's study offers environmentally friendly solution to oil industry needs

... shape.In contrast, the current technique used for separating proteins, gel electrophoresis, is time-consuming and less predictable. Pore sizes in the gels vary, and the process itself is not well understood by scientists. "No one has been able to measure the gel pore sizes accurately," said Jongyoon Han, the ...

"If you tried to harvest some native grass seed with a combine, it would plug in 30 seconds," Arbuckle said. Nationally, more than 100 economically significant native grass...

High-tech research shows cocaine changes proteins and brain function

...pressed at a given time) between the two groups by separating all of the proteins and then using high-throughput mass spectrometry which allowed the accurate identifcation of thousands of proteins simultaneously, Hemby said. The unbiased nature of the technology enables the determination of novel proteins and p...

Genes offer researchers a 'crystal ball' to help them prevent, diagnose and treat cancer

... to Perner, fusion can occur when the piece of DNA separating the genes breaks off and the genes merge (a process described as "fusion through deletion"), or if parts of each gene break off and switch positions ("translocation"). They found that TMPRSS2-ERG fusion through deletion was more common in the tumo...

UCLA researchers unravel a mystery about DNA

In the Dec. 12 issue of the weekly Journal of the American Chemical Society, the researchers report invention of a method for mass-producing identical copies of SWCNTs. It starts with a "seed" SWCNT of the desired type. The seed is us...

Chromium picolinate shows greater benefits in diabetes care than other forms of chromium

...ll types of chromium at widely varying doses. But separating out chromium picolinate, which yields highly consistent results in research studies, compared to other chromium supplements shows that at doses between 200--1000 mcg it is a superior nutritional adjunct to diabetes treatments."

Virtual duck bills demonstrate species coexistence

...ioned." "Foraging ducks are faced with the cost of separating food particles from detritus particles like sand and silt" said Gurd. "To do this, they alter the position of the upper and lower bill while they are feeding. This alters the size of the gap between the lamellae on the upper and lower bill, which all...

Notorious cancer gene may work by destroying messenger

...the two were bound together, capturing both. After separating the two, the investigators identified the enzyme as Src, which is a member of a large family of molecules called tyrosine kinases. These molecules act like switches that turn other molecules on and off, including PMR1. That's the real excitement a...
