Many of you have seen the rubber wristbands that adorn the celebrity wrists at the moment but do you really exactly what they indicate that? There are certain shavers that are worn for breast cancer and certain for general cancer and sometimes even ones for little ones with cancerous. There are an unlimited amount of bracelets purchase your for a variety of triggers. That is why however called awareness bracelets. This month is cancer wristbands month and traditionally supported by companies producing items several sell however in pink. There are so many events organised this month in aid of Cancer Research and many of them involve people wearing pink, either a pink bra for The Moon Walk or a little pink bows. It is great to support a charity prefer that and much better if they even make the right pink that. Create an instinctive make up look with a bronzer and employ a deep pink wwjd wristbands lipstick.

BEIJING - Chinese scientists have identified the crucial factor that activates gene expression in human embryos, bringing them a step closer to explaining the mystery of human development at a very early embryonic stage, according to a paper published on the website of the scientific journal, Cell.

Human life starts from a fertilized egg. However, in the first two days after fertilization, almost no genes are expressed in human embryos. Previously scientists did not know how genomes become active and start gene expression in early embryos.

"What activates gene expression? The puzzle has been troubling scientists around the world for a long time. We were the first to find it," said Liu Jiang, senior author of the paper.

During human growth, different genes must be expressed at the right time and right place. The genetic code stored in DNA is "interpreted" by gene expression, which gives rise to all the particular features of an individual.

A team from Beijing Institute of Genomics, Chinese Academy of Sciences (CAS), led by Liu, together with a group from Center for Reproductive Medicine, Shandong University, under Chen Zijiang, and a group from Guangzhou Medical University under Liu Jianqiao, found that Oct-4, a transcriptional factor, plays a crucial role in activating zygotic genome expression.

In the first two days, a human zygote will grow into eight cells after three cell divisions. Once the embryo has eight cells, it will generate a sufficient amount of Oct-4, which will directly bind with DNA and switch on the gene expression, Liu said.

The research also found genome activation follows a particular sequence. "The older genes usually start expression at early embryonic stages, and younger ones at later stages," Liu said.

Humans have more than 20,000 genes, a reflection of a long chain of evolution. Some genes originated at the beginning of life on Earth, and are thus very old genes. Some originated in mammals, and are young ones. Some originated only in humans, and are deemed the youngest.

"We found that the expression of older genes usually occur at earlier embryonic stages, as these genes, shared by more life species, are needed during earlier development," Liu said.

But how human genome differentiates between old and young genes is still unclear and needs further study.

The study also found that transposons, a class of DNA elements, are very active in early human embryos, which might be a trigger of evolution.

"These transposons can jump from one position to another in a genome, and introduce DNA mutations. Since they are only active in early embryos, but not in differentiated tissues, the mutations caused by their mobility are more likely to be passed to the germ line, and then to the next generations," Liu said.

"As DNA mutations drive evolution, we believe that these active transposons have a big impact on human evolution," he said.

Before this study, the major hurdle in this research was the limited number of human embryos for experiment. Similar research would normally consume millions of animal embryos, but acquiring so many human embryos was neither possible nor ethical.

"We optimized the experiment methods so that the research could perform the assay with a very small number of human embryos," Liu said.

According to the paper, the scientists used just 50 to 100 cells, all derived from in vitro fertilization with written consent from donor couples.
