Importance of Gene in Eye Development

...n factors. Transcription factors are proteins that bind to DNA and regulate the expression of other genes. The investigators discovered that, in mice, disruption of the SOX2 gene in neural retinal stem cells leads to a kind of abnormal development of the eye called microphtalmia, or small eye. Approximate...

Anti-Sense Drugs and Nanotechnology Offer New Hope In Cancer Fight

...the DNA modified nanoparticles act as sponges that bind to their targets and prevent them from being converted to proteins,’ said Chad Mirkin, lead author of the study. ‘Powerful new cancer drugs will only live up to their potential if they can be efficiently delivered to cancer cells. This study accomp...

The new face of vaccine development

...power to effectively see how the body's antibodies bind to the chains of sugars on the outer coats of bacteria. In cases where antibodies don't bind to the sugars and no immune response is triggered, researchers could chemically alter the sugars so ...

Finnish research: Cysteine Chewing Gum as a cure for cancers of the mouth

...es that a harmless aminoacid l-cysteine is able to bind effectively acetaldehyde and thereby eliminate its toxicity. On this basis professor Salaspuro and professor Martti Marvola, University of Helsinki, started to develop l-cysteine containing and acetaldehyde eliminating preparations that eventually co...

Three-Dimensional Image Of AIDS Virus – BY FSU Researcher

...s and macrophages. ‘Antibodies that effectively bind to either of these spike parts will neutralize the virus to prevent infection,’ said Roux, a member of FSU's biological science faculty since 1978. His biggest surprise: the stalk has legs. ‘Researchers thought the spike stalk was comprised of ...

Genetic Link to Adrenal Tumor Revealed

... For a hormone to affect the cell, it must first bind to a molecule, or receptor, on the cell's surface, analogous to how a key fits into a lock. This action triggers the cell to produce substances known as cyclic nucleotides. These function as 'second messengers,' often stimulating the cell to begin an...

Hunt for Chromosomal Errors Which Cause Genetic Diseases

...rt fragments of DNA, called oligonucleotides, that bind to complementary stretches of DNA within a sample being tested. These microarrays hold more than 100,000 DNA oligonucleotides, which allow researchers to rapidly analyze a person’s whole genome — the entire complement of DNA in a cell nucleus. “The...

New Molecular Treatment Identified To Treat Blood Cell Cancers

... These antibodies have drawbacks, however: They bind to healthy lymphocytes along with malignant ones; in addition, they do not bind to T cells and therefore can't be used to treat T-cell lymphoma. In contrast, LLP2A binds to both B-...

Bioinformatics Made a Boon In Immune Response Study - LIAI Finds

...ne response. By understanding, which epitopes will bind to the MHC molecule and cause an immune attack, scientists can use those epitopes to develop a vaccine to ward off illness – in this case to smallpox. The scientists were able to find 95 percent of the MHC binding epitopes through the computer mode...

Protected Environment v/s Unprotected Affect Hygiene Health Immunity

...tem kicks into action by producing antibodies that bind to the invader and destroy it. Of the many clas... In the wild animals, the autoreactive IgG likely bind to environmental antigens and therefore do not have deleterious effects, Parker said. "However, a...

Brain Cancer Could be Safely Treated with Radioactive Scorpion Venom

... As Jackson discovered, the TM-601 that does not bind to cells in the body is rapidly excreted in the urine. ‘Other tissues will receive some dose,’ he says, ‘but the vast majority of the dose is delivered to the cancer cells.’ To prevent the radioactive compound from being absorbed by the thyroid, whic...

Researchers Find Molecular "Brake" to Cell Death

...rganelle's energy storehouse. These molecules then bind to another protein called Apaf-1 in the cell cytop...uce the size of the nucleotide pool to allow CC to bind to Apaf-1, Tang says. The researchers say this kind of strategy makes sense for the cell, because ...

How Does Leptin Work?

...bolism and other processes. ‘Leptin is known to bind to cell-surface receptors in the hypothalamus and then to activate various other cellular signals including a molecule called STAT3--but the role of STAT3 in mediating leptin's multiple physiological effects was still unknown,’ says Dr. Luciano Rosse...

DNA-bound p53 Tumor Suppressor Protein Structure Determined

...consistently resulted in structures that could not bind to DNA. (Crystallization is a prerequisite for obt...an inactive form of the p53 dimer that's unable to bind DNA in the correct fashion," Marmorstein explains. "We knew there had to be a structural rearrangeme...

Research Finds That Nicotine Hastens The Growth Of Lung Cancer

...ed that nicotine caused a molecule called Raf-1 to bind to a key protein called Rb, which normally suppresses tumors. Chellappan explained that this interference with the Rb protein's function could make the cancer spread faster. He further explained that 8 out of 10 tumors that were examined by his gro...

Gene Responsible For Mammary Gland Function, When Mutated Results in Leukemias

Protein May Offer New Hope For Treatment Of Cystic Fibrosis

...r’. They further explained that these enzymes also bind to a protein, which is responsible for causing cystic fibrosis. The researchers believe their work could have a major impact on treatment of cystic fibrosis, adult-onset diabetes and some forms of childhood cancer. Dr Mehta said, “It has long been ...

A New Approach towards Anti-Cancer Drugs

...mber of protein fragments which has the ability to bind to the MDM2 protein and inhibit its activity as a cancer promoting catalyst. This study is being sponsored by the Cancer Research UK. Prof. John Toy, medical director of this organization said that p53 plays a crucial role in conserving stability ...

Malaria Truths Discovered By Einstein Researchers

...e Bronx Bomber enzyme; a section of DNA that would bind the plasmid to a complementary section of DNA inside P. falciparum; and a marker gene fused with a green fluorescent protein that would light up if the marker gene became functional. The Bronx Bomber transfection technique proved remarkably successfu...

Protein's Role in Triggering Cancer Identified

...UK, we have identified protein fragments which can bind to MDM2, inhibiting its activity. These fragments could be a good template for drugs designed to hinder the role of MDM2 in the p53 destruction pathway. We hope our findings may lead to improved treatments for a broad range of cancer types.' Welcom...
