Inexpensive, mass-produced genes core of synthetic biology advances at UH

...slow (and tedious) process of genecloning, or gene modification (mutations, deletions, etc). Devices the size of a pager now have greater capabilities thancomputers that once occupied an entire room. Similar advances are beingmade in the emerging field of synthetic biology at the University ofHouston, now allowin...

Breakthrough Microarray-based Technology for the Study of Cancer

...NAS paper, Agilent'sbreakthrough is founded on the modification of its gene-expressionprofiling microarray technology to improve its utility for DNA analysisapplications. This new platform provides high sensitivity, enabling CGHresearchers to reliably identify the single copy deletions inchromosomes that have bee...

Genetically modified natural killer immune cells attack, kill leukemia cells

...hile in remission and then reinfused after genetic modification if the patient suffers a resurgence of the leukemia. "We look forward to seeing this strategy being added to the management of children with ALL," said Chihaya Imai, M.D., the postdoctoral student who did most of the work on this project. ...

New RNA polymerase discovered in plants

...ethylation is a vital process involving a chemical modification in cytosine, one of the four chemical subunits of DNA. Without proper DNA methylation, higher organisms from plants to humans have a host of developmental problems, from dwarfing in plants to tumor development in humans to certain death in mice. Pik...

Variation in women's X chromosomes may explain differences among individuals, between sexes

...y of the female's X chromosome are switched off, a modification known as X inactivation. Originally, scientists had assumed that the inactivation process resulted in complete silencing of the genes on the second X chromosome, Willard said, in order to leave both sexes with the same activity level, or dosage, of ...

Protein helps regulate the genes of embryonic stem cells

... called "eed," is needed for an essential chemical modification of many genes. Embryos cannot survive without the modification. The findings appear in the May 24 issue of the journal Current Biology. The research offers an important contribution to a new wave of thinking in genetics: that not all human disease s...

Putting ecology back into river restoration

... is to do no lasting harm. "For example, a channel modification project should minimise loss of native vegetation during river reconstruction, and should avoid the fish spawning season for construction work," Palmer explains. The final criteria is ecological assessment. According to Palmer: "It is critical that t...

Brain May Be Less Plastic Than Hoped

...ation in these areas might then depend more on the modification of existing patterns of connectivity, be it subcortical, feedback, or other broad area-to-area connections. Of course, that is highly speculative. It is also conceivable—although in our opinion less likely—that in neocortical areas other than the pri...

Sponges as drugs

...ced techniques such as chemical synthesis, genetic modification and sponge cell culture are realised, rearing in the sea remains the most reliable and effective method for obtaining the large quantities of sponge biomass, necessary for developing drugs. However, sea rearing can only be used for the large-scale p...

Biologists determine genetic blueprint of social amoeba

...on appears to lead to loss of genes as well as the modification of copies of old genes. As each new genome is sequenced, we learn more about the history and physiology of the progenitors and gain insight into the function of human genes."

Gene therapy advance treats hemophilia in mouse models

...ts promoter is liver-specific," McCray said. "This modification helps prevent negative side effects. For example, if the gene were expressed in immune cells instead of liver cells, it could lead to a damaging immune response." McCray said the team now is studying additional ways to make the hybrid vector express...
