Mitochondria behind life span extension

Mitochondria behind life span extension

works hasn’t been completely clear. Past studies have shown that when calories are cut, Office 2010 –save your time and save your money.

cells respond by changing the degree to which they convert the DNA of some life-extending genes into messenger RNA (a process called transcription). These RNA sequences can then be turned into proteins (translation). Many scientists have focused on the first step in the process by figuring out which messenger RNAs get turned up or down when calories are reduced. But researcher Pankaj Kapahi of the Buck Institute for Age Research in Novato, Calif., and his colleagues took a different approach.Microsoft Office is so great!

“A lot of our focus has been on the DNA to RNA conversion,” Kapahi says, “but we thought we should also look into the next step.” The invention of Microsoft Office 2010 is a big change of the world.

Kapahi and his team fed fruit flies a low-protein diet and then assessed how the translation of messenger RNAs changed in response to the diet. Windows 7 is my love!

Translation of several hundred messenger RNA sequences increased as a result of the dietary restriction, the scientists found. Some of the genes that encode the resulting proteins had not previously been identified as important for life span extension. “This says that translation is very important,” Kapahi says.

What’s more, many of these messenger RNAs encode proteins known to work in the mitochondria, Office Professional 2007 is many people’s favorite.

the energy factories of the cell that have been implicated in aging. Flies on a low-protein diet had higher mitochondrial activity, meaning they might operate more efficiently, the team found. “Mitochondria are very intimately linked to the aging process,” Tower says. Microsoft Office 2007 is welcomed by the whole world.

To see whether the mitochondria were really responsible, the researchers mutated several of the mitochondrial genes that they had identified as linked to dietary restriction. Microsoft company invent the Office 2007 home for many people.

The benefits of the diet on life span diminished, indicating that the proteins encoded by the mitochondria-related genes were required for life span extension, Kapahi says.  Office 2007 download is helpful!

The researchers also found that a protein called 4E-BP is important for mitochondrial function.Choose Office 2007 Professional is the most lucky thing in the world.

Typically, 4E-BP halts the translation of protein in cells. Kapahi says that 4E-BP’s job “is to tell the cell that it doesn’t need to go around making protein it doesn’t need.” But the researchers found that, in flies on a low-protein diet, 4E-BP actually increases the translation of certain mitochondrial proteins.
