Gene Therapy for the Treatment of Brain Tumors

By Thobeka P. In bread wheat Triticum aestivum L. Timely flowering is critical for production, and the flowering window has to be late enough to avoid early season frosts but early enough to avoid late season stresses such as heat and terminal drought. Tailoring flowering time could help reduce preharvest sprouting problems by escaping high temperatures and late season rainfall, which promote preharvest sprouting, hence yield loss. Concisely summarizing available information on flowering time and identifying research gaps could provide direction for future research. This chapter, therefore, discusses: i the progress made in discovering genes involved and the impact of their extensive allelic variation on flowering time, ii the potential benefits of tailoring wheat’s flowering time to improve yield, and iii the benefits of introgressing genes for other complimentary traits, such as semidwarf and preharvest sprouting resistance on advanced lines to achieve higher yield, thus, sustainable food security.

Evidence exists that deregulation of apoptosis is involved in the mechanisms of cancer development, and the somatic mutations of apoptosis-related genes have been reported in human cancers. To explore the possibility that the genetic alterations of Bad might be involved in the development of human cancers, we analyzed the entire coding region and all splice sites of human Bad gene in 47 colon adenocarcinomas. Overall, we detected two somatic missense mutations 4.

Interestingly, both of the Bad mutations were detected in the gene sequences encoding the Bcl-2 homology3 domain of Bad, which has a crucial role in inducing cell death. Transfection study revealed that both of the tumor-derived Bad mutants had decreased apoptosis activities compared with the wild-type Bad, indicating that the Bad mutations reduced the cell death function of Bad.

Co-immunoprecipitation assay revealed that binding of one of the tumor-derived Bad mutants with Bcl-2 and Bcl-X L is reduced.

At age six, 32 percent of the kids had tooth decay and 24 percent of the children had advanced cavities. To see how much genetics might shape the risk of cavities, researchers looked at how often both kids got cavities in pairs of identical twins – who have identical genetic variations – and fraternal twins – who typically share about half of their variations. Worldwide, an estimated 60 to 90 percent of school age children have tooth decay, potentially resulting in pain, infection and hospitalization, researchers note in Pediatrics.

Toothache can also result in school absence, poor nutrition, compromised growth and development, and impaired quality of life for children and parents alike. Childhood cavities are also the strongest predictor of poor oral health in adulthood, the study team writes. In the current study, both twins had cavities in 29 pairs; in another 33 pairs of twins, just one child was affected.

Both kids had advanced cavities in 26 pairs of twins, and another 31 pairs had just one child with advanced cavities. Three environmental factors in particular appeared to impact the risk of cavities: maternal obesity, defects in tooth enamel mineralization, and lack of community water fluoridation. Obese mothers, for example, might be more likely to feed kids unhealthy food that can contribute to cavities. And defects in tooth enamel mineralization that lead to weak enamel that can easily break down and form cavities may start developing in the womb and early childhood.

This may be caused by certain medications taken by women during pregnancy or by children early in life, as well as by poor nutrition and certain diseases in early childhood. Discover Thomson Reuters. Directory of sites. United States.

Fruit Fly Scientists Swatted Down Over ‘Cheap Date’

Their plan is to use a virus, injected into the brain, to turn cells into a factory that makes a weapon to lower the harmful huntingtin protein. Huntingtin lowering can be attempted using many different technologies to achieve a single goal: reduce the levels of mutant huntingtin protein in cells. HD is caused by a mutant version of the gene that we tend to refer to as the HD gene.

The gene is the root cause of HD, but the main mischief maker is the mutant huntingtin protein that the gene is a recipe for.

The love formula in dating sites was all about category-matching: prospective partners were matched according to their self-selected characteristics, keywords and answers to personality questionnaires. In , partners will be matched according to genetic compatibility and psychometric characteristics, processed by sophisticated love algorithms.

Dating sites will be replaced by a complementary offer of centralised and decentralised dating platforms. The centralised platforms will have the added capability of offering precise recommendations. For example, if you liked this blonde girl in Manchester, you will also like this blonde girl in New York. Decentralised, user-owned dating platforms will contain private data that would be too intrusive to be processed by the centralised systems such as the time and location of actual dates.

Behavioural geneticists have known for years that partners in long-term relationships have similar genes. The easiest way to determine how genetically close individuals are is to analyse their saliva samples. The dating ecosystems will combine genetic models with detailed personality testing.

Genes influence every aspect of human physiology, development, and adaptation. Obesity is no exception. A study found that consumption of fried food could interact with genes related to obesity, underscoring the importance of reducing fried food consumption in individuals genetically predisposed to obesity. Rapid advances in molecular biology and the success of the Human Genome Project have intensified the search.

This work has illuminated several genetic factors that are responsible for very rare, single-gene forms of obesity.

It is logical to think that genetic factors may underlie many traits already used by matching sites – like personality and empathy – which many assume could promote initial chemistry and long-term potential in specific couples. So it is perhaps not surprising that there are now websites that combine genetic testing and matchmaking. But does matching intimate partners on the basis of specific genes have any scientific foundation?

Studies have shown that genetically identical twins, raised separately, rate the overall quality of their marriages similarly, suggesting some enduring genetic contribution to marital life. However, the specific genes that are relevant to marriage, and why, remain a mystery. As such, predicting marital compatibility on the basis of specific combinations of genetic profiles rests on tenuous scientific footing.

Currently, researchers are just beginning to identify the genes that may be associated with marital bliss and through what processes. As a scientist and clinical psychologist , I have a longstanding interest in identifying the factors that contribute to a happy marriage , such as how couples manage conflict.

My interest in exploring genetic determinants, however, developed more recently. Genes are segments of DNA that encode a particular trait. Differences in genotype correspond to observable differences within that trait across individuals.

Gene therapy carries the promise of cures for many diseases and for types of medical treatment that didn’t seem possible until recently. With its potential to eliminate and prevent hereditary diseases such as cystic fibrosis and hemophilia and its use as a possible cure for heart disease, AIDS , and cancer , gene therapy is a potential medical miracle-worker.

But what about gene therapy for children? There’s a fair amount of risk involved, so thus far only seriously ill kids or those with illnesses that can’t be cured by standard medical treatments have been involved in clinical trials using gene therapy. As those studies continue, gene therapy may soon offer hope for children with serious illnesses that don’t respond to conventional therapies.

Malignant brain tumors are responsible for a significant amount of deaths in children and adults. Even with advances in surgery, radiation therapy, and chemotherapy, many patients diagnosed with a malignant brain tumor survive only months to weeks. In an attempt to improve the prognosis for these patients, researchers have developed a new approach to brain tumor therapy.

This approach makes use of DNA technology to transfer genes sensitive to therapy into the cells of the tumor. Infections with the herpes simplex virus can cause cold sores in the area of the mouth.

Individuals who have, or are at risk for, various genetic disorders face many challenges concerning disclosures of genetic information in dating situations. At times, these individuals feared and experienced rejection, and hence delayed, avoided, or opposed disclosure, or disclosed indirectly or inadvertently. This paper, the first to explore several key aspects of disclosures of genetic information in dating, thus suggests needs for public and professional education, and future research in this area.

Yet, little attention has been given to disclosures of genetic information in these contexts—what challenges patients face, and how they approach these. We recently conducted an in-depth qualitative study, exploring the research questions of what issues individuals who had or were at risk of a genetic disease faced, and how they viewed and addressed these—including issues of understandings, privacy, and disclosures of genetic information.

We explored disclosure to various groups of individuals e.

Some cod species have a newly minted gene involved in preventing freezing. In the depths of winter, water temperatures in the ice-covered Arctic Ocean can sink below zero. A protein in its blood and tissues binds to tiny ice crystals and stops them from growing. Where codfish got this talent was a puzzle that evolutionary biologist Helle Tessand Baalsrud wanted to solve. She and her team at the University of Oslo searched the genomes of the Atlantic cod Gadus morhua and several of its closest relatives, thinking they would track down the cousins of the antifreeze gene.

None showed up. Baalsrud, who at the time was a new parent, worried that her lack of sleep was causing her to miss something obvious.

The protein encoded by this gene is a member of the BCL-2 family. BCL-2 family members are known to be regulators of programmed cell death. This protein positively regulates cell apoptosis by forming heterodimers with BCL-xL B-cell lymphoma-extra large and BCL-2, and reversing their death repressor activity. Proapoptotic activity of this protein is regulated through its phosphorylation. Protein kinases AKT and MAP kinase, as well as protein phosphatase calcineurin were found to be involved in the regulation of this protein.

Alternative splicing of this gene results in two transcript variants which encode the same isoform. Gene Ontology GO annotations related to this gene include protein heterodimerization activity and lipid binding. Genes Participants. Jump to section.
