After years of exploration, scientists have mastered the basic biological features of many sugar molecules, but compared to DNA and protein, not enough for us to understand these molecules, however, due to the complex structure of sugar, in order to build This molecule is very difficult, and the DNA is different from the glycoside is almost impossible for cloning and amplification, and therefore the number is limited. Sugar chips by a small amount and more types of natural or synthetic…Continue

Recently, Professor Lin Yiwen China Taiwan China Pharmaceutical University, suggested that many researchers have attempted to combine the concept of nerve regeneration and nerve recovery into another treatment of neurodegenerative diseases. To solve this problem, we need to know more about how neurons express in a natural environment, because most of the cells are surrounded by brain tissue in an organ or a different hardness range of fat and cartilage.…Continue

Researchers from an evolutionary perspective to understand the development of tumors, the individual cells develop into tumors in the process as a short-term evolution of cellular events. The article points out, multicellular organisms have evolved in order to maintain the multi-cell genetics some restrictions. In theory, the cancer may be the result of such restrictions occur due to the collapse.
Researchers through the complete life cycle of a transplanted tumor to show people,…Continue

Adult stem cells as a type of cells with specific differentiation potential, widespread presence of various tissues and organs of multicellular organisms, and with the maintenance of tissue homeostasis and regeneration functions. In a stable environment, adult stem cells to maintain tissue homeostasis in two ways: one way is asymmetric division, stem cells when each division, one daughter cell remains a stem cell while the other daughter cells differentiate into the state. This approach is…Continue

In addition to the non-reproductive potential of human cell lines, scientists should not even try to human germ cells for gene editing. But the article also acknowledged for germ cell gene editing or explain things like infertility and other basic scientific problems. And edited by a single gene embryonic cells can also help elaborate the key issues early human embryonic development.
However, germ cell gene editing will be accompanied by a number of negative effects can not be…Continue

EHEC can cause more severe symptoms, in addition to diarrhea can also lead to serious complications and sequelae, such as hemorrhagic colitis and hemolytic uremic syndrome, about 3-75% of cases, death. In the survivors, 30% display chronic renal failure, hypertension and nervous system damage. Both pathogenic organisms have two major virulence characteristics areas show the difference: EHEC can generate Shiga toxin, but EPEC can not; EHEC and EPEC settlers settled in the large intestine to…Continue

He calls himself the bug hunter, but the target of his work consists of viruses that can only be found and identified with special methods and instruments. Benjamin Hause, an assistant research professor at the Kansas State Veterinary Diagnostic Laboratory at Kansas State University, recently published an article about one of his discoveries, porcine enterovirus G, which is an important find in the United States.
"We had isolated a virus in cells, but didn't know what it was," Hause…Continue

CTLA-4 gene is located on the long arm of chromosome 2 33 band (2q33), mainly expressed on activated T cells, collaboration and stimulate T cell surface receptor molecule (CD28) with a high degree of homology. CTLA-4 and CD28 are both members of the immunoglobulin superfamily, both with the same ligand CD86 (B7-2) and CD80 (B7-1) combined. In contrast with the function of CD28, CTLA-4 and B7 molecules upon binding inhibition of T cell activation.
CTLA4 and B7 molecules with high…Continue

High expression level, easy operation, short circle, low cost and easy cultivation with high density and large-scale are the advantages of prokaryotic expression system. To complete antibody and glycoprotein biological drugs, the synthesis, secretion ,bio-activation, stability in vivo and immunogenicity of the expression product are often affected by the folding of the peptides , the forming of disulfide bond , the type of glycosylation and whether has glycosylation or not. The product is…Continue
