Scientists detect probable genetic cause of some Parkinson's disease cases

Two new studies strongly suggest that amutation in a recently discovered gene is the most common genetic causeof Parkinson's disease identified to date. The discovery by aninternational research team provides fresh evidence that genetics maycontribute to the development of some cases of Parkinson's disease. Thefindings could lead to the development of a genetic test to detect themutation in...

Found: Missing sequence of the human Y chromosome

Scientists report today in the journal GenomeResearch that they have successfully cloned and characterized apreviously intractable DNA sequence: a 554-kilobase-pair genomicsegment near the centromere of the human Y chromosome. This sequencecontains eight putatively active genes that could be implicated insex-associated height differences and gonadal tumor development. Thispericentrom...

Needling Chromosomes Reveals Cell Division Secret

By impaling individual chromosomes with glassneedles one thousandth the diameter of a human hair, a Duke Universitygraduate student has tested their "stickiness" to one another duringcell division. Her uncanny surgical skills have added a piece to thelarge and intricate puzzle of how one cell divides into two -- aprocess fundamental to all organisms.In the Dec. 14, 2004, issue of Current Bi...

Variation in women's X chromosomes may explain differences among individuals, between sexes

The first comprehensive survey of gene activity in the X chromosomes of women has revealed an unexpected level of variation among individuals, according to new work by researchers at the Duke University Institute for Genome Sciences & Policy (IGSP) and Pennsylvania State University. The results may have important implications for understanding the differences in traits among women and...

Antiretroviral therapy may prevent excess risk of some cancers in people with HIV

In people infected with human immunodeficiency virus (HIV), highly active antiretroviral therapy (HAART) may prevent most excess cases of Kaposi sarcoma and non-Hodgkin lymphoma, according to a new study in the March 16 issue of the Journal of the National Cancer Institute. Studies of people with acquired immunodeficiency syndrome (AIDS) have reported increased risks of several cancers, in...

Analyzing The Side Effects Of Some Common Medications

A new study shows a connection between the use of two of the most common medications -- beta-blockers and diuretics and a reduced risk for // bone fractures. Beta-blockers are commonly used to treat high blood pressure, congestive heart failure, chest pain, and abnormal heart rhythms. Some heart attack patients also receive the drugs to prevent a second attack. Diuretics are used to remov...

Chromosome Ends Trigger DNA Damage Response For Telomere Protection

Chromosomes to predict oral cancer

The DNA content in cells of oral leukoplakia, specifically the number of chromosomes, can be used to predict the risk of oral carcinoma, according to study.// 123 patients were taken up for research for an average of 8.5 years, found that oral leukoplakia with the normal number of chromosomes — 46 — were unlikely to develop into cancer. Of the 103 patients with leukoplakia with normal DNA...
