ob gene造句

• With the ob gene, they may now start piecing it together.
• Leptin is produced by another gene, the OB gene, and is secreted by fat cells.
• When the gene, called the ob gene, is absent or defective, it may result in obesity.
• That one, called the ob gene, influences appetite.
• Researchers found that a mouse with a flawed ob gene becomes grossly obese and eventually develops diabetes and other fatal conditions.
• In two strains of obese mice, the ob gene was found to be defective, suggesting that when it malfunctions, it causes obesity.

• The ob gene produces a hormone, dubbed leptin, that was reported last month to have caused dramatic weight loss in severely obese mice.
• The researchers then used the mouse gene to scan through human DNA, the genetic material, which led them to the human ob gene.
• The researchers found that a minority of their volunteers carried Ob genes that contained up to 10 fewer DNA " letters " than normal.
• Comings intends to explore this addiction theory by seeing if the presence of the short Ob gene also correlates with alcoholism and other substance abuse.
• People who carry two defective Ob genes are extremely rare, however, which means that similar treatment is still unlikely to prove an all-purpose cure for obesity.

• The ob gene instructs fat cells to secrete a hormone called leptin, which travels through the bloodstream and signals the brain when the body has stored enough fat.
• In the new experiments, the scientists isolated the ob gene through elaborate cloning methods, seeking differences in genetic markers between the DNA of fat mice and of normal mice.
• Scientists also reported two weeks ago that a third obesity-linked gene, called tub, has been discovered in mice and, like the ob gene, may have a counterpart in humans.
