Humans are not 'peas in a pod' says a study

...sts of many letters like a regular book. The human genome consists of over 3 billion letters and about 30,000 genes can be compared to pages of a book with around 100,000 letters each. Earlier it was understood that variations between individuals was seen owing to changes in individual letters that altere...

From a Lowly Yeast, Researchers Divine a Clue to Human Disease

...t regulation of individual genes but not the whole genome at once. Using yeast, a small and relatively simple organism, the Wisconsin group developed a method to get a broad view of how Sen1 works and what happens when it doesn't work properly. Normally, Sen1 acts like a molecular stop sign, telling anoth...

Protein ‘Fingerprint’ in Spinal Fluid Could Spot Alzheimer’s Disese

...controls without the disease. “Just as the human genome reflects the array of genes a person possesses, the ‘proteome’ is the vast collection of proteins expressed by those genes,” said Lee. “Essentially we used high-tech methods to contrast the proteomes of Alzheimer’s patients against those of a control...

Study Explains How NSAIDs Halt Cancer Growth

...cular mechanisms that were at work.” Using whole genome microarray analysis, Libermann and first author Luiz Zerbini, PhD, a researcher in the BIDMC Genomics Center and Instructor of Medicine at HMS, examined more than 20,000 genes to identify potential mechanisms for cell death induction. “When we anal...

Researchers Create Genetically-Matched Embryonic Stem Cells for Transplantation

...ugh parthenogenesis may have some regions of their genome that contain duplicated copies of mutant genes that have been linked with malignancies or abnormal tissue growth. “Right now this technique is useful for basic research, but we are hopeful that parthenogenetic cells might prove useful for therapies...

Researchers Make Progress in Studying Genetic Traits of India-born Populations

...in terms of the total number of sites in the human genome that were surveyed. The researchers found that populations from India, and more generally, South Asia, make up one of the major human ancestry groups, with relatively little genetic differentiation among the Indian populations. Although the study ...

‘Nasty’ Bug Mapped Don

...g with 66 researchers from 10 countries mapped the genome of Trichomonas vaginalis and published the genomic sequence in the journal Science. The ‘nasty bug’ Trichomonas is observed to have almost as many genes as the human genome. Carlton is hopeful that the research will help identify ways of diagn...

Understanding Autoimmune Disease

...y technology developed by Young to scan the entire genome of T cells and locate the genes controlled by Foxp3. There were roughly 30 genes found to be directly controlled by Foxp3 and one, called Ptpn22, showed a particularly strong affinity. "This relation was striking because Ptpn22 is strongly associat...

Role of RNA in Checking the Development of Tumors

...roteins. The remaining part – in fact, most of the genome – constituted what was considered to be "junk" DNA with no function. However, latest estimates show that this "junk" DNA produces around half a million varieties of RNA of unknown functions. "There's been a quiet revolution taking place in biology ...
